Best Tax Return Software in Germany [2026] - Live In Germany

In 2026, there are at least seven solid tax return software options available in Germany, and the best ones now support English well enough that filing your Steuererklärung (annual tax return) no longer requires a law degree or a very patient German colleague.

When I moved to Wolfsburg in 2022 and filed that year’s return, I spent an embarrassing amount of time staring at forms before finally committing to one of these tools properly. It made a real difference. Not just in time saved, but in the refund I actually received.

Germany’s tax system involves terminology and deductions that genuinely confuse native speakers, so the language barrier for expats is a real obstacle. According to the Bundeszentralamt für Steuern (Federal Central Tax Office), over 15 million electronic tax returns were submitted in Germany in 2024, and that number keeps climbing as people abandon paper forms and expensive Steuerberater (tax advisors) for straightforward cases. The tools have improved fast enough to justify that shift.

The platforms worth your attention in 2026 include WISO Steuer, Smartsteuer, Taxfix, Sorted, SteuerGo, Elster, and a few others. Some have built English-language interfaces from the ground up. Others have added them more recently. Newer platforms like Taxfix and Sorted have specifically designed their products around the international resident experience, handling things like partial-year residency, foreign income, and double taxation agreements under German Doppelbesteuerungsabkommen (double taxation treaty) rules.

This guide breaks down every major option honestly. No software paid for placement here. I looked at English support, ease of use for both employees and Freiberufler (freelancers), pricing, and how each tool handles the specific situations expats actually face. If you have been wondering whether WISO Steuer has a usable English version, or what the difference between Taxfix and Smartsteuer actually is in practice, you will find a straight answer below.

How Do You Actually Get Your Taxes Back in Germany?

Germany runs on a pay-as-you-earn system. Your employer deducts Lohnsteuer (income tax) from your gross salary every month before a single euro hits your account. The problem is that those deductions are based on broad assumptions. They take into account your Steuerklasse (tax class), whether you have children, and a handful of other variables. By the time December rolls around, there’s a very real chance the Finanzamt (German tax office) has taken more than it was actually owed. Filing a Steuererklärung (annual tax return) is how you claim that difference back.

The numbers make a compelling case for bothering. According to Destatis, the average tax refund in Germany in 2026 sits at around €1,095 per return filed. Most people who file receive a refund rather than a bill, which makes the whole exercise well worth your time even if German paperwork feels like a second job at first.

There are four main ways to submit your Steuererklärung, and they differ significantly in cost, language support, and how much guidance you actually get.

Tax return software or an app is the most popular route for employed expats. Tools like WISO Steuer, Smartsteuer, and Taxfix walk you through the entire process step by step, often in English or simplified German. If you’re comparing the best tax return app Germany offers, or wondering whether WISO Steuer’s English support is sufficient for your situation, this is where that question gets answered. The rest of this guide covers exactly that comparison.

A Steuerberater (licensed tax advisor) handles everything for you. It’s the most thorough option and the most expensive, typically running between €150 and €500 depending on the complexity of your finances.

A Lohnsteuerhilfeverein (non-profit income tax assistance association) charges a modest annual membership fee, usually scaled to your income, and a volunteer advisor prepares your return. The scope is limited though. Lohnsteuerhilfevereins can only assist employees and pensioners, not freelancers or self-employed residents.

ELSTER, the official free portal run by the German tax authorities, lets you file directly without any subscription. It’s reliable and costs nothing, but it’s entirely in German, offers zero guidance, and assumes you already know what you’re doing. Most expats find it more trouble than it’s worth unless they’re genuinely comfortable navigating German bureaucracy on their own.

How To File Your German Tax Return

There are four realistic ways to file your Steuererklärung (German tax return) in Germany, and the right choice depends entirely on your situation.

Tax software is the most popular route for expats, which is exactly why this article exists. These tools, whether desktop programs or browser-based apps, walk you through every field step by step and submit your return electronically to the Finanzamt (German tax authority). The best tax return software in Germany typically costs between €15 and €40 for a full tax year. According to Destatis, the average German tax refund in 2026 sits at around €1,095, so even the priciest option on this list pays for itself many times over.

The second option is a Lohnsteuerhilfeverein (non-profit tax assistance association). Membership fees are income-based and usually reasonable. The catch is a legal one: these associations can only assist employees with straightforward employment income. Freelance income, rental income, or anything more complex puts you outside their permitted scope.

A Steuerberater (certified tax advisor) is the third path and genuinely the right call if you are self-employed, running a business, or dealing with cross-border income. Fees typically start at €300 for a basic return and climb from there. For complicated situations the expertise is worth every euro. For a Kleinunternehmer (small business owner under Germany’s simplified VAT threshold) with clean, simple finances, though, a good tax app will almost always be the more cost-effective choice.

Then there is Elster, the official free option. It is the government’s own filing portal, operated by the Bayerisches Landesamt für Steuern (Bavarian State Office for Taxation) on behalf of all German tax authorities, and it handles everything from simple employee returns to complex business filings. The honest downside is that Elster is German-only and assumes you already understand how German tax law works. For experienced filers who just want to skip the software fee, it is perfectly functional. For everyone else, the learning curve is steep enough that one of the dedicated tax apps in this article will save you real time and frustration.

The table below gives you a quick comparison so you can match your situation to the right filing method before reading further.

The German tax year runs from January 1 to December 31, and your return covers the previous calendar year. If you are filing voluntarily as an employee, you have four years to claim a refund, which means in 2026 you can still submit returns going back to 2022. If you are self-employed or otherwise required to file, the standard deadline is July 31 of the following year, though a Steuerberater can usually get you an extension to the end of February the year after that.

Before you open any software, gather your documents. The most important one is your Lohnsteuerbescheinigung, the annual wage and tax statement your employer sends you by the end of February. It summarises exactly what you earned and what taxes were already withheld during the year. You will also want your Steuernummer (tax number) or your Steuerliche Identifikationsnummer (the permanent 11-digit ID issued at birth or registration). If you have moved, changed jobs, paid church tax, contributed to private insurance, or had any investments, pull those statements together too.

Once you are inside a tax app, the process typically follows the same logical flow regardless of which tool you choose. You start with your personal situation, marital status, whether you have children, and whether you are registered in Germany for the full year or only part of it. From there you enter your income data, usually by typing figures directly from your Lohnsteuerbescheinigung. Then come the deductions: work-related expenses (Werbungskosten), special expenses (Sonderausgaben) like pension contributions or donations, and extraordinary burdens (außergewöhnliche Belastungen) if they apply to you. The software calculates your result in real time as you work through each section, so you can see whether you are heading for a refund or a back-payment before you commit to anything.

When everything looks right, you submit directly to the Finanzamt through the app’s built-in Elster interface. Every major tax app in Germany routes submissions through Elster in the background, so you get the polish of a consumer product with the official government submission channel underneath. You will receive a confirmation number, and a few weeks later your Steuerbescheid (tax assessment notice) arrives by post. Check it carefully when it does. You have one month to file an objection (Einspruch) if something looks wrong, and mistakes on the Finanzamt’s side are not unheard of.

What Documents Must You Submit to the German Tax Authority?

The short answer is: nothing upfront. When you file digitally through tax software or an online platform, no physical paperwork gets sent to the Finanzamt alongside your return. No payslips, no receipts, no invoices. The submission is entirely electronic.

That said, “nothing upfront” does not mean “nothing at all.” The Finanzamt reserves the right to request supporting documents after reviewing your return, and when that letter arrives, you want everything already organised. Under the Abgabenordnung (German Fiscal Code), taxpayers must generally retain relevant records for up to ten years depending on the expense type, so keeping a dedicated folder, digital or physical, is genuinely useful.

For most employed expats, the documents worth having ready before you start filing are:

• Lohnsteuerbescheinigung (annual wage tax certificate): your employer sends this digitally to the Finanzamt, but you receive a copy too. It is the single most important document you will need.
• Receipts for Werbungskosten (work-related deductible expenses), such as home office costs, professional training fees, or your commuting distance
• Contribution statements from your Krankenversicherung (statutory or private health insurance) provider
• Spendenquittung (charitable donation receipts) if you plan to claim deductions
• Your IBAN for the refund transfer
• Rental income statements if applicable
• Childcare or school fee confirmations if claiming family-related deductions

Before any of this matters, you need your Steuernummer (tax identification number assigned by your local Finanzamt upon Anmeldung, or address registration). This is distinct from your Steuer-ID, which is a permanent national identifier issued automatically. Most tax software will ask for both. If you have never received a Steuernummer, you can apply through the official ELSTER portal, though allow several business days for it to arrive by post.

One practical detail that often surprises people: the Finanzamt can retrieve your Lohnsteuerbescheinigung data directly from your employer’s records. Several tax platforms that connect through the ELSTER interface can prefill this information automatically, which cuts down on manual entry and reduces the risk of transcription errors. According to the Bundeszentralamt für Steuern (Federal Central Tax Office), over 14 million tax returns were submitted electronically via ELSTER in 2024, a figure that reflects just how normalised digital filing has become in Germany.

The process is less paper-heavy than many expats expect. What matters is that the documents exist, are accurate, and are within reach if the Finanzamt comes back with questions.

Five of Germany’s Best Tax Return Software (English Interface)

If your German stops somewhere around “Guten Morgen” and “Danke schön,” you are genuinely not alone. The good news is that several solid tools now offer a full or near-full English interface for filing your Steuererklärung (annual income tax return). The options below are worth your time in 2026.

Taxfix

Taxfix is probably the most foreigner-friendly option available right now. The app walks you through your return in plain English using a simple interview format. You answer questions, and it builds the return behind the scenes. It handles employment income, Kindergeld (child benefit) situations, and standard deductions well. Where it falls short is anything involving freelance income or rental properties, so if your situation is more complex than a standard employee filing, you will hit its ceiling quickly. Pricing in 2026 sits at €39.99 per return for standard filers.

Wundertax

Wundertax is another English-first option that tends to be popular among expats in their first or second year in Germany. The interface is clean, the guidance is genuinely helpful, and it covers common expat scenarios well. That includes partial-year residence, Doppelbesteuerungsabkommen (double taxation agreement) situations, and Kirchensteuer (church tax) questions. It is web-based rather than app-based, which some people actually prefer when sitting down to tackle something as consequential as their taxes. A single return costs €34.99 in 2026.

WISO Steuer

WISO Steuer is the heaviest hitter on this list. It is the best-selling tax software in Germany, and for good reason. The depth of coverage is unmatched at its price point. It handles rental income, investment income (Kapitalerträge), self-employment, and deductions under § 9 EStG, which is the section of the German Income Tax Act covering work-related expenses. The English interface is solid without being quite as polished as Taxfix or Wundertax, so there is a slightly steeper learning curve. That said, once you are past the setup, the power it gives you is worth the effort. A 2026 licence costs around €29.99 for the app version, with a web version also available.

Smartsteuer

Smartsteuer runs on a flat fee of €34.99 per year in 2026, regardless of how many returns you file. That makes it excellent value for couples filing jointly. The English guidance is solid for most standard situations, and the interface is modern and browser-based. It is not the best choice for highly complex returns, but for employed expats with some additional deductions to claim, it punches above its weight.

SteuerGo

SteuerGo rounds out the list as a pay-per-return option at €39.99 in 2026. The English interface is clean and the question-based flow is easy to follow. It covers the typical expat filing scenarios and integrates directly with ELSTER, which is the official German tax authority’s electronic submission system, for secure submission. According to the Bundeszentralamt für Steuern (Federal Central Tax Office), ELSTER-connected tools like SteuerGo submit returns directly to your Finanzamt (local tax office), cutting out any manual steps.

SteuerGo

SteuerGo occupies an interesting position in the German tax software market. It is not the most feature-packed option available, but it does one thing better than almost anyone else: it lets you see your estimated refund before you pay a single euro. For anyone filing a Steuererklärung (annual income tax return) for the first time in Germany, that alone removes most of the anxiety from the process.

The workflow is genuinely straightforward. You work through a guided questionnaire written in plain language rather than the dense bureaucratic phrasing you would find on an actual Finanzamt form. Once you reach the end, SteuerGo calculates your estimated refund and shows it to you upfront. Only at that point do you decide whether to pay and submit. The 2026 price is 34.95 EUR as a one-time fee per tax year, with no subscription attached.

What genuinely sets SteuerGo apart from many competitors is language support. The full interface runs in English, which matters enormously if your German is still a work in progress. It also supports Polish, Hungarian, and several other European languages. That reflects the actual reality of who files taxes in Germany. According to Destatis, more than 13 million people living in Germany held foreign citizenship in 2025, and a significant share of them have tax filing obligations that German-only software simply does not serve.

SteuerGo also handles the post-submission phase, which most tools ignore entirely. When your Steuerbescheid (tax assessment notice) arrives from the Finanzamt, SteuerGo can cross-check it automatically for errors. If something looks wrong, it provides templates and guidance for filing an Einspruch (formal objection against the assessment). Tax assessment mistakes do happen, and having structured help to catch and challenge them is more valuable than it sounds.

The software runs entirely in your browser with no installation required, and data from previous years carries over automatically. It covers employees, pensioners, families with children, and people with rental income from real estate. It will not suit someone with complex freelance income across multiple income streams, but for the majority of employed expats it covers everything relevant.

WunderTax – GermanTaxes

WunderTax launched in 2015 with a clear goal: help students in Germany file their Steuererklärung (annual income tax return) online without needing to understand the full bureaucratic machinery behind it. Within a year the platform had expanded well beyond students. Today it serves employees, self-employed individuals, civil servants, soldiers, and police officers. That’s a broader scope than most people expect from a tool that started with such a narrow focus.

What genuinely sets WunderTax apart in a crowded field of German tax software is its English interface. This isn’t a rough translation bolted on as an afterthought. The entire interview-style process runs in English from start to finish, including the guidance notes and tax tips. For expats still building their German or simply unwilling to gamble on tax terminology in a second language, that matters enormously. According to Destatis, over 13 million people living in Germany in 2026 have a migration background and are employed subject to social insurance contributions. A large portion of them are exactly the kind of users WunderTax is built to serve.

The workflow is practical and low-friction. No account is required to get started, a live refund calculator runs in the background as you answer each question, and the whole process is designed to take around 17 minutes. You only pay once you actually submit your return. That removes the risk of paying upfront before you know whether the result justifies the cost. No prior year’s tax data is needed either, which makes WunderTax a particularly solid option if you’re filing a German Steuererklärung for the very first time.

Pricing starts at €34.95, though Live in Germany readers get an exclusive €5 discount. For a tool with a genuinely functional English interface and a guided process that doesn’t assume you already understand German tax law, that’s a fair price. Comparable Steuerberater appointments in Germany can cost €150 or more for a basic return, according to the Steuerberaterkammer (Chamber of Tax Advisors). WunderTax sits well below that threshold and handles most standard expat scenarios without any German required.

TaxFix

TaxFix has become one of the most downloaded tax apps in Germany, with over 5 million downloads to date. The reason it caught on so quickly is pretty obvious once you actually use it. The whole experience is built around a guided question-and-answer flow: you answer roughly 70 questions about your financial situation, and the app assembles your Steuererklärung (annual tax return) from those responses. Most people finish in under 30 minutes, which is genuinely impressive given how dense German tax law can be.

For expats still building their German tax vocabulary, the full English interface is the real selling point. Most German tax software defaults to legal terminology that can feel impenetrable if you are not already comfortable with terms like Werbungskosten (work-related deductible expenses) or Sonderausgaben (special deductible expenditures). TaxFix sidesteps that barrier entirely by running the whole interface and customer support in English. The app also lets you photograph your Lohnsteuerbescheinigung (annual wage tax certificate issued by your employer) and imports the figures automatically, which cuts out a surprising amount of manual entry.

Pricing is transparent. You can calculate your estimated refund for free before committing to anything, and payment only kicks in when you actually submit. In 2026, that is €39.99 for a single return and €59.99 for married couples or registered civil partnerships filing jointly. Submission goes through the official ELSTER interface, the same secure government channel used by every compliant tax software in Germany, so your data is not taking some unofficial shortcut to the Finanzamt (local tax office).

Where TaxFix has limits is worth knowing upfront. It is designed for employees, students, Rentner (pensioners), trainees, and civil servants with straightforward income. If you are self-employed, work as a Freiberufler (registered freelancer), earn income from rental property, or receive a private pension, you will run into a wall fairly quickly. Those situations require software with access to additional forms that TaxFix simply does not support.

For a salaried expat with a clean income picture, though, TaxFix is hard to beat on ease of use. The ELSTER-certified submission, English support, and free refund preview make it a strong default choice for anyone who just wants to get the return done without a German tax dictionary open in another tab.

Taxando

Taxando sits in an interesting middle ground in the German tax software market. It is not as feature-rich as WISO Steuer or as polished as Taxfix, but it does something most competitors do not bother with: genuine multilingual support from day one. The app runs in German, English, Polish, Russian, Italian, Bulgarian, and Romanian. For expats filing their Steuererklärung (annual tax return) for the first time and still finding their feet with the language, that is a meaningful advantage, not a marketing footnote.

The free-to-calculate model is fairly common now, but Taxando applies it honestly. You work through your entire return, see your estimated refund, and only pay when you are ready to submit. The standard plan costs 33.80 EUR and covers straightforward employment income. Step up to the premium plan at 99 EUR and you get something that actually justifies the price jump. A qualified Steuerberater (certified tax advisor) reviews your return before it goes to the Finanzamt, and you can ask questions directly. That is a real human, not an automated checklist. For anyone with a situation that falls slightly outside the obvious, having trained eyes on the numbers before submission is genuinely reassuring.

The standard plan does have real limitations worth knowing upfront. Freelancers, the Selbstständige (self-employed), and anyone with rental income, Kapitaleinkünfte (investment income), or cryptocurrency gains will not find support there. Those situations require the premium tier or a different tool entirely. Students can technically use the standard plan, though Taxando does not position itself specifically toward them the way some other apps do.

One feature worth flagging for expats specifically is international income declaration. Germany operates under a worldwide taxation principle, meaning income earned outside Germany during the tax year must generally be declared here. According to the Bundeszentralamt für Steuern (Federal Central Tax Office), taxpayers with foreign income are subject to this obligation regardless of where the income was originally taxed. Not all basic-tier apps handle this properly. Taxando supports it, though only through the premium plan.

The platform runs entirely in the browser, so there is nothing to install and it works across devices. That is fairly standard in 2026, but it still beats dealing with software that only runs on Windows.

SmartSteuer

SmartSteuer launched in 2010 and has grown into one of the more trusted names in German online tax filing. It’s now part of Lexware, a German accounting software company operating since 1989, which gives it a solid institutional backbone. The platform runs entirely in the browser, so there’s nothing to install and no compatibility headaches to worry about.

What genuinely sets SmartSteuer apart from several competitors is its language support. The interface can be translated into around 100 languages via Google Translate, and English customer service is available at no extra cost. For expats who can navigate German bureaucracy reasonably well but still want an English safety net when things get confusing, that combination is genuinely practical. If you’ve ever tried to decode a Steuerbescheid (tax assessment notice from the Finanzamt) using only your phone’s camera translate function, you’ll understand why having real English-language support on standby matters.

The pricing is straightforward. In 2026, SmartSteuer costs €39.99 for up to five Steuererklärungen (tax returns) filed within the same calendar year. That flat fee means you can handle returns for other household members without paying separately for each one, which makes it particularly good value for couples where both partners are employed. You only pay once your return is actually submitted, so there’s no risk of paying upfront and then deciding the software doesn’t suit your situation.

The workflow is question-based, walking you through each section rather than presenting you with a blank form and expecting you to know what goes where. Previous year data carries over automatically, and SmartSteuer runs an automatic data check before submission to catch obvious errors. A free refund estimate is available before you commit to anything. Once submitted, your return is sent securely to the Finanzamt via ELSTER, the official electronic tax submission system operated by the Bayerisches Landesamt für Steuern on behalf of all German tax authorities.

One feature worth highlighting is the Einspruch (formal objection) support. If the Finanzamt sends back a Steuerbescheid you disagree with, SmartSteuer provides letter templates and guidance for filing a challenge. Most casual filers never think about that until they’re staring at a disappointing assessment and wondering what to do next. Having structured support for that process built into the same platform you used to file is a practical convenience.

SmartSteuer sits at a slightly higher price point than entry-level options like Aldi Talk’s SteuerSparErklärung, but the English support and multi-return flat fee justify the difference for most expat households.

Three Best Tax Return Software In Germany With A German Interface

If you have even a working knowledge of German, tax software built around a German interface is genuinely worth considering. These tools are engineered specifically around the Einkommensteuergesetz (German Income Tax Act), which means they handle edge cases, life-event deductions, and complex Werbungskosten (work-related expense) categories that English-language tools sometimes flatten or skip entirely. The depth of guidance on offer is simply hard to replicate in a translated version.

“German interface” does not automatically mean “impossible for non-native speakers,” though. The better tools use plain, step-by-step language, and if you can already navigate a Nettolohn (take-home pay) slip or handle your Anmeldung (official address registration) without help, you can likely manage. The learning curve is real, but so is the payoff.

According to Destatis, Germany processed over 38 million individual income tax returns in 2024, with the majority filed through dedicated Steuersoftware (tax software) rather than paper forms or the free ELSTER portal run by the Finanzverwaltung (German tax authority). That alone tells you how embedded these tools are in everyday German life. The three options below represent the most widely used and consistently reliable German-interface choices available in 2026 for anyone comfortable navigating in German.

TaxMan

TaxMan is produced by Lexware, a German accounting software company that has been around since 1989. That kind of track record matters in a country where the tax code changes every year and fly-by-night software solutions quietly disappear between filing seasons. The product reflects that experience: it is thorough, well-structured, and genuinely built for the German Steuererklärung (annual income tax return) rather than adapted from something generic.

The most immediately obvious thing about TaxMan is that it is desktop software. You download it, install it, and everything stays on your local machine. For expats used to browser-based tools, that might feel dated. For anyone who prefers their Steueridentifikationsnummer (tax identification number), bank details, and investment data to stay off a third-party server, it is actually a meaningful advantage. Not every privacy-conscious decision is a trade-off.

Where TaxMan genuinely earns its place is in handling complexity. Standard employee with one income source and a few Werbungskosten (deductible work-related expenses)? Any decent tool handles that. But if you have Selbstständigkeit (freelance or self-employment income), Kapitaleinkünfte (capital gains from investments), or rental income from a property, TaxMan covers all of it without pushing you toward a more expensive tier. That breadth is the real selling point. According to Destatis, in 2026 around 16.2 million taxpayers in Germany file with desktop tax software, and TaxMan has held a consistent position in that category for well over a decade.

The software guides you through each section step by step, with built-in checklists and explanatory notes that are more detailed than most competitors offer. A live refund estimate updates as you fill in figures, so you can see the impact of each entry in real time. Data from the previous year transfers directly, which saves a noticeable amount of time for anyone filing annually. There is also a receipt manager built into the software itself, letting you upload and organise supporting documents alongside your return rather than hunting through folders when the Finanzamt (local tax office) asks a question.

Customer support is included at no extra cost, which is worth flagging because some tools charge separately for it. TaxMan also provides free templates for filing an Einspruch (formal objection) against your Steuerbescheid (tax assessment notice), which is useful if the Finanzamt comes back with a figure that does not look right. One licence covers up to five tax returns, so households with multiple filers get reasonable value from a single purchase.

The honest limitation is language. The interface is entirely in German, with no English option. For expats still working through the language, that creates real friction, and the detailed guidance that makes TaxMan useful for complex situations only helps if you can read it. It is a strong tool for anyone with intermediate German or the patience to work through it with a dictionary open.

Wiso Steuer

Wiso Steuer is probably the most fully-featured tax software available in Germany right now. Developed by Buhl Data, a German company building financial software since the early 1990s, it has the kind of depth that newer competitors simply haven’t had time to develop. According to Buhl Data’s own published figures, over 2.8 million returns are submitted through the platform each year, which says a lot about how broadly it’s trusted across different types of filers.

What genuinely sets Wiso apart from lighter tools is the range of life situations it covers without breaking a sweat. Employees, students, pensioners, couples filing a gemeinsame Veranlagung (joint assessment), homeowners, investors, and the self-employed can all use it without hitting a ceiling. If you have Nebeneinkünfte (secondary income) alongside your regular salary, whether that’s rental income, freelance earnings, or capital gains from a Depot (securities account), Wiso handles it. That breadth matters more than people realise, because tax situations tend to get more complicated over time. You really don’t want to discover mid-filing that your current software can’t process your new rental income or your first year of self-employment alongside employment.

The software guides you through each field with contextual help text keyed to the relevant paragraphs of the Einkommensteuergesetz (EStG, Germany’s income tax law). The structure follows the logic of the actual Steuererklärung (income tax return), so it isn’t arbitrary, even if it can feel dense at first. Wiso also pulls data directly from ELSTER (the official German tax portal) where available, which reduces manual entry errors on pre-filled figures like your Lohnsteuerbescheinigung (employer’s annual wage tax certificate).

One limitation worth naming directly: Wiso Steuer is a German-language product. There is no official English interface, and if you’ve been searching “Wiso Steuer English” hoping to find a localised version, that doesn’t exist as of 2026. The contextual guidance helps, and intermediate German speakers usually navigate it fine. But if you’re still building your language skills, a tool like Taxfix or Sorted will serve you better for now. German tax terminology is specific enough that even a B1 reading level can leave you uncertain about whether you’re filling something in correctly.

Pricing for the 2026 tax year sits at around €39.99 for the download version, with the online version priced slightly differently depending on your subscription tier. According to Wiso’s own published user data, the average refund processed through the platform exceeds €1,000 per submission. That figure isn’t surprising given how much a properly filed Steuererklärung can recover across Werbungskosten (income-related expenses), Sonderausgaben (special deductions), and Vorsorgeaufwendungen (pension and insurance contributions). The software is thorough enough that it actively prompts you for deductions you might have overlooked, which is where a lot of that refund value comes from.

For expats specifically, Wiso handles the filing requirements for unbeschränkte Steuerpflicht (unlimited tax liability, which applies once you’re a resident in Germany) and can manage cross-border income situations with some configuration. It isn’t marketed as an expat tool the way some newer apps are, but its depth means it covers most scenarios that come up in an international worker’s life once you’re comfortable enough in German to use it.

ELSTER

ELSTER (Elektronische Steuererklärung, meaning “electronic tax declaration”) is the official free platform run by Germany’s Finanzverwaltung (tax administration authority). It has been the backbone of online tax filing in Germany for decades, and it remains the only completely cost-free way to submit your Steuererklärung (annual tax return) digitally. According to the Bundeszentralamt für Steuern, over 16 million tax returns were submitted through ELSTER in 2024, so it clearly has a serious user base.

The zero cost is the headline advantage. For someone who already understands German tax law, knows which Steuerformulare (tax forms) apply to their situation, and is comfortable working entirely in German, ELSTER does exactly what it promises. There are no subscription fees, no upsells, and your data stays within the official government infrastructure rather than passing through any third-party servers.

The problems start when you move outside that narrow profile. ELSTER runs exclusively in German with no English interface planned for 2026, and more importantly, it offers no guided workflow. You are expected to arrive knowing what deductions you are entitled to under § 9 EStG (the German Income Tax Act covering income-related expenses) and which forms cover your specific circumstances. The platform will not prompt you toward anything you have not already thought of yourself. For expats with foreign income, freelance arrangements, or rental property, that gap in guidance can quietly cost more than any paid software subscription would have.

Registration adds another layer of friction. Your first login requires a certificate-based activation code sent by post, a process that typically takes two weeks from request to receipt. If you are trying to file close to the July 31st deadline without a tax advisor, that postal delay alone can create real pressure.

For most expats comparing tax return options in 2026, ELSTER works well as a backup or for genuinely simple cases, a salaried employee with one income source, no foreign assets, and solid German skills. For anyone else, the paid tools covered in this guide will almost certainly recover their cost through deductions ELSTER would never have flagged.

Conclusion

Picking the right tax software genuinely makes a difference to how much you get back and how much time you waste getting there. Germany’s tax system is one of the more complex ones in Europe, and the wrong tool really can leave money on the table. According to the German Federal Central Tax Office (Bundeszentralamt für Steuern), the average refund for employees who filed a Steuererklärung (annual income tax return) in 2026 was around €1,095. That is not a number worth ignoring.

For most expats with straightforward employment income, Taxfix remains the most intuitive option. The interview-style flow means you are never staring at a blank form trying to remember what Anlage N (the attachment for employment income) actually covers. If your situation is more complex, with freelance income, property, or investment portfolios, WISO Steuer gives you the depth you need without requiring a Steuerberater (tax advisor). It is worth adding that WISO Steuer’s English-language support for the core workflow is genuinely usable, not a help page run through Google Translate. Smartsteuer sits comfortably in between: solid English guidance, no desktop software required, and a price point that makes sense if you only file once a year.

There is no single best tax app in Germany for everyone. The right tool for a salaried employee in Lower Saxony looks completely different from the right tool for a freelance designer splitting invoices across two clients and a home office deduction. What the tools in this article share is that any of them will outperform filing manually through Elster, especially when German bureaucratic vocabulary is still not second nature.

When I filed my first Wolfsburg-based return in 2022, the biggest win was not finding the perfect software. It was simply starting early enough that I had time to dig out my Lohnsteuerbescheinigung (annual wage tax certificate from your employer) without panic. That document alone unlocks most of what the software needs from you.

My practical final tip: do not wait until the Abgabefrist (filing deadline) arrives. For voluntary filers, that deadline is 31 July of the following year. If a Steuerberater is handling your return, it extends to 28 February. Start in March while your documents are still organised, run through your chosen software once, and you will likely be done in a single afternoon with money on its way back to your account.
