Tax Returns in Germany: Who Files, Deadlines, Elster, and Tax Refunds

A tax return in Germany—Steuererklärung—is not required for every employee, but it is mandatory in many situations. Even if there is no legal obligation, people often file a tax return voluntarily to claim a refund of overpaid taxes after moving, changing jobs, incurring significant expenses, or having capital gains tax withheld incorrectly.

This guide explains when the Finanzamt expects your tax return, what documents you’ll need, how to file your return via Elster, what to do after receiving your Steuerbescheid, and why it’s best not to miss the deadlines.

What Is an Einkommensteuererklärung?

For individuals, this usually refers to the income tax return—Einkommensteuererklärung. In it, the taxpayer reports income for the calendar year, taxes already withheld, and expenses that can reduce the tax base.

People who live in Germany or have their habitual residence here generally become tax residents of Germany. After registering at their place of residence () and obtaining a residence permit (), immigrants are often required to comply with German tax regulations. Income from abroad may also be relevant: the specific procedure depends on residency status, the type of income, and any double taxation agreement with another country.

Income tax in Germany is progressive. No income tax is levied on income up to the Grundfreibetrag. For 2026, the basic tax-free allowance is 12,348 euros per person; for 2025, it is 12,096 euros. If income exceeds this amount, the tax rate increases on a sliding scale.

What Types of Income Should Be Reported on the Tax Return

Various categories of income can be reported on the tax return:

employment and withheld Lohnsteuer;
business activities;
self-employed professionals, such as doctors, lawyers, engineers, or journalists;
capital gains: interest, dividends, ETFs, and securities;
real estate rentals;
pensions and certain types of payments;
certain income from the sale of property;
Foreign income, if it is relevant for taxation or the progressive tax rate.

Not all income automatically results in an additional tax payment. Some tax is already withheld by your employer or bank. You need to file a tax return so that the Finanzamt can compare the withheld amounts with your actual annual situation.

Who Is Required to File a Tax Return

An employee is often not required to file a tax return if they have only one regular job and their employer withheld taxes correctly. However, the obligation arises in the following typical cases:

You had additional income or payments that affect your tax rate, such as benefits, compensation, or foreign income;
the person worked for several employers at the same time;
The spouses used tax classes III/V or IV/IV with a factor;
Individual tax-free allowances (Freibeträge) have already been taken into account in the calculation of your salary;
Did you receive severance pay upon termination of employment or termination of a contract?
You changed employers during the year, and your new employer did not take your previous employer’s information into account;
you have income from self-employment, a business, rent, or other sources;
The Finanzamt has specifically requested your tax return.

A “Minijob” does not in itself always create an obligation to file a tax return if it is taxed under separate rules. However, it’s best to check combinations of income on a case-by-case basis.

When It’s Advantageous to File a Tax Return Voluntarily

A voluntary tax return is called an Antragsveranlagung. It is often filed by employees who are not required to file a return but wish to claim a tax refund.

This may be helpful if, during the year, you:

commuting expenses, professional training, a home office, or moving expenses;
medical, family, or other special expenses;
periods of unemployment, study, parental leave, or moving to Germany;
working only part of the year;
Excessive tax withheld by the bank on capital investments;
donations or expenses for household services.

A tax refund is especially common in the year of relocation. Your employer withholds tax from your German salary, but your total annual income may turn out to be lower than what was assumed in the monthly calculations. For more details: taxes in Germany in the year of relocation.

A voluntary tax return can usually be filed within four years after the end of the tax year.

Payroll Tax: Lohnsteuer

Income tax is called Lohnsteuer. The employer calculates it based on the employee’s information and transfers it to the Finanzamt with each paycheck. The pay stub—, Lohnabrechnung, Entgeltabrechnung, or Gehaltsabrechnung—shows how much has been withheld for taxes and social security contributions.

At the end of the year, your employer issues or sends you electronically a Lohnsteuerbescheinigung. You’ll need this document for your tax return: it lists your annual salary, withheld Lohnsteuer, church tax (if applicable), Solidaritätszuschlag, and social security contributions. For more details: Lohnsteuerbescheinigung.

Capital Income and Anlage KAP

Interest, dividends, and many types of income from securities are usually taxed through the bank: Abgeltungsteuer is withheld. In this case, the Sparer-Pauschbetrag applies—1,000 euros per person or 2,000 euros for married couples filing jointly.

To prevent the bank from withholding tax up to this amount, you must submit a Freistellungsauftrag. If you did not submit one, if the limit was allocated incorrectly, or if your personal tax rate is below 25%, you can request a recalculation via your tax return and the Anlage KAP form.

If you incurred losses from the sale of securities, it’s also important to report them correctly. The Finanzamt or your bank can carry forward such losses to offset future income of the same type.

How to File a Tax Return

Via Elster

The official method for electronic filing is Elster. To register, you need access to your personal data and a confirmation sent according to the established procedure. After registering, the taxpayer receives an electronic certificate or another means of login, which is used to sign and submit the tax return.

Through Elster, you can fill out your tax return online, upload available tax data, and submit your return without a paper signature. Detailed instructions: Elster step-by-step guide:.

Entrepreneurs, the self-employed, and many individuals with business income are generally required to file their tax returns electronically.

Using tax software

Commercial tax software helps you fill out the forms by asking questions in plain language. This is convenient if your situation is standard and you understand German tax terminology. However, the taxpayer remains responsible for the accuracy of the information provided.

Through a Tax Advisor (Steuerberater) or Income Tax Assistance Association (Lohnsteuerhilfeverein)

A Steuerberater or Fachanwalt für Steuerrecht can be helpful if you have foreign income, own a business, rent property, are in a dispute with the Finanzamt, are moving, have investments, or face the risk of having to pay additional taxes.

If your tax return involves only rental income and standard deductions, you can contact a Lohnsteuerhilfeverein. These associations assist employees and retirees within the scope permitted by law in exchange for a membership fee.

The cost of a tax advisor depends on your income, the scope of work, and fee schedules. A fixed price found online may be inaccurate, so it’s best to confirm the price before work begins.

On Paper

Paper forms are still an option, though not for all cases, and are gradually becoming less common. If paper filing is permitted, the forms must be signed and sent to the Finanzamt in your place of residence. For a joint tax return filed by spouses—Zusammenveranlagung—both spouses must sign.

Which forms are most common?

The set of supporting documents depends on your income and expenses. Commonly required documents include:

the main Einkommensteuererklärung form;
Anlage N for employees;
Anlage Vorsorgeaufwand for insurance and pension expenses;
Anlage Kind for expenses and information regarding children;
Anlage KAP for capital gains;
Anlage V for rental property;
Annexes for the self-employed, entrepreneurs, and foreign income.

Tax software and Elster usually prompt you on which sections are required, but it’s best to consult a specialist for complex cases.

What Documents to Gather

For your tax return, it’s helpful to prepare the following in advance:

Lohnsteuerbescheinigung and your most recent pay stubs;
Tax ID and, if applicable, tax number;
bank statements showing interest, dividends, and withholding tax;
lease agreements and statements of real estate expenses;
receipts for vocational training, work tools, and moving expenses;
proof of commuting to work;
statements regarding benefits, sick leave, parental leave, or unemployment;
documents related to foreign income;
Receipts and invoices for expenses claimed as deductions.

Usually, you don’t have to submit all the documents at once. You can keep them on file and provide them upon request by the Finanzamt. If you’re claiming a large or unusual amount, be prepared to explain how you arrived at that figure.

Filing Deadlines

For mandatory tax returns, the standard deadline for self-filing is July 31 of the year following the tax year. For example, the tax return for 2025 is usually filed by July 31, 2026.

If a tax return is prepared by a tax advisor (Steuerberater) or a wage tax assistance association (Lohnsteuerhilfeverein), the deadline is usually longer. Following pandemic-related extensions, deadlines have gradually returned to normal, so for a specific tax year, it’s best to check the date on the Finanzamt website, via Elster, or with your advisor.

A voluntary tax return can usually be filed by the end of the fourth year following the tax year in question. For example, for the year 2025, the deadline is December 31, 2029.

What Happens After You File

The Finanzamt reviews the tax return and requests additional documents if necessary. A deadline for responding is usually specified in the letter; if you can’t meet it, you can request an extension.

After the review, you’ll receive a Steuerbescheid—a tax assessment notice. It specifies:

what income and expenses are taken into account;
which deductions are disallowed;
how much tax has already been withheld;
whether you’ll receive a refund or owe additional tax;
By what date must you pay if there is a Nachzahlung?

If you’re due a refund, the money will be transferred to the account you specified. If you owe additional tax, the payment deadline is specified in the decision.

How to File an Einspruch

If the Steuerbescheid appears to be incorrect, you can file an Einspruch. The deadline is usually one month after receiving the decision. In your appeal, you must specify exactly what you disagree with and attach supporting documents or arguments.

Important: Filing an Einspruch (appeal) does not automatically waive the obligation to pay the specified additional amount by the due date. If you wish to suspend enforcement, this requires a separate request—Aussetzung der Vollziehung.

Moving Away from Germany

If a person leaves Germany in the middle of the year, their tax obligations for that year do not automatically disappear. It is often necessary to file a tax return for the period during which they were a German tax resident and to report income that affects their tax rate or tax liability.

Before leaving the country, you must file a deregistration () and a change of address (). It’s also helpful to notify the Finanzamt of your new address and clarify whether the tax return for the year of your departure will be your last.

What Are the Consequences of Missing the Deadline?

If filing a tax return is mandatory and you fail to file it on time, the Finanzamt may:

send a reminder about the filing and set a new deadline;
impose a Verspätungszuschlag—a late-filing penalty;
impose penalties or interest in cases provided for by law;
assess your income yourself and issue a Steuerbescheid based on that assessment;
take enforcement measures if the taxpayer ignores the requirements.

For a late mandatory tax return, the Verspätungszuschlag is often calculated as 0.25% of the tax amount for each month or part thereof that the return is late, with a minimum of 25 euros per month; however, the specific calculation depends on the situation and the law.

Criminal Risks

Intentionally failing to file a tax return or concealing income can escalate from an administrative offense to Steuerhinterziehung—tax evasion. This may result in fines and, in severe cases, imprisonment.

Threshold amounts and consequences depend on the circumstances, case law, and the taxpayer’s conduct. Therefore, in cases of missed tax returns, foreign income, or significant underpayment, it is best not to rely solely on the advice in this article but to consult a tax advisor (Steuerberater) or a tax lawyer.

Quick Checklist

Check whether you are required to file a tax return.
Gather your Lohnsteuerbescheinigung, Steuer-ID, bank statements, and receipts for expenses.
Decide whether to file on your own via Elster or to consult a specialist.
Check the deadline for your specific tax year.
Keep your receipts and documents, even if you don’t submit them right away.
After receiving your Steuerbescheid, compare it with your tax return.
If there is an error, don’t miss the deadline for filing an Einspruch.

FAQ

Do you need to file a tax return every year after your first voluntary filing?

No, filing voluntarily does not, in and of itself, make filing a tax return an annual obligation. The obligation arises from specific circumstances: income, tax brackets, Finanzamt requirements, and other factors.

Is it possible to receive an additional payment instead of a refund?

Yes. This can happen if too little tax was withheld during the year or if the person was actually required to file a tax return. In simple cases involving a voluntary return, you can assess the risk in advance using Elster or tax software.

Do I need to include all receipts?

Usually not. Documents are kept on file and sent to the Finanzamt upon request. However, claimed expenses must be verifiable.

Where can you find official information?

To file, use Elster and the tax administration websites for your state. For complex cases—especially those involving foreign income, business activities, rental income, investments, and missed deadlines—it’s safer to seek personalized advice.
