Tax return in Germany: the basics every employee should know

Filing a tax return in Germany sounds daunting, but for most employees it is a manageable annual task that often ends with a refund. Your employer already withholds income tax each month, and the return, called Einkommensteuererklärung or simply Steuererklärung, lets the tax office settle the exact amount for the year.

This guide explains who must file, the deadlines, the main forms and the deductions employees most often claim. It is general information, not tax advice. Rules change regularly, so check the current guidance from the tax authorities or ask a tax adviser for your situation.

Do I have to file a tax return in Germany?

Many employees with a single job and no other income are not required to file, because tax is already withheld from their salary. However, the law lists several situations in which filing is mandatory. Self-employed people and freelancers generally have to file every year.

• You are married and use the tax class combination III/V, or IV with a factor
• You had more than one employer at the same time, including a job taxed in class VI
• You received wage-replacement benefits above a small threshold, such as unemployment benefit, parental allowance or sickness benefit
• You had other income without tax withheld above a small threshold, such as rental income
• An allowance was entered for withholding purposes, with some exceptions
• The tax office asks you to file

Tax return deadline in Germany

If you are required to file and do it yourself, the standard deadline is 31 July of the following year. If a tax adviser or an income tax help association (Lohnsteuerhilfeverein) prepares your return, the deadline is generally extended to the end of February of the second following year. When a deadline falls on a weekend or public holiday, it moves to the next working day.

Missing a mandatory deadline can lead to a late-filing surcharge and, in some cases, interest. If you need more time, ask the tax office for an extension before the deadline and give a reason.

For many employees, the German tax return is an annual task that ends with a refund.

Voluntary tax returns: up to four years back

If you are not obliged to file, you can still submit a return voluntarily, and many employees should. You generally have four years from the end of the tax year to do so. That means you can still claim a refund for several past years in one go.

A voluntary return can usually be withdrawn if the assessment turns out worse than expected. That makes it low-risk for people who are unsure whether a refund is likely.

Which forms do employees need?

The German tax return is made of a main form and annexes (Anlagen). You only fill in the ones that apply to you. Most people file electronically through the tax administration's official online portal, which pre-fills data the tax office already has, such as your wage tax certificate and many insurance contributions.

• Main form (Hauptvordruck): personal details, bank account, special expenses
• Anlage N: employment income and work-related expenses
• Anlage Vorsorgeaufwand: health, care, pension and other insurance contributions
• Anlage Kind: one per child, for child allowances and childcare costs
• Anlage Haushaltsnahe Aufwendungen: household services and tradespeople's labour costs
• Anlage KAP: investment income, if you want to claim back tax or were not fully taxed
• Anlage Sonderausgaben and Anlage Außergewöhnliche Belastungen for other deductions

Common tax deductions for employees in Germany

Work-related expenses (Werbungskosten) are the most important deductions for employees. The tax office automatically applies a flat allowance for them, so itemising only helps when your real costs are higher. The commuting allowance alone often pushes people over the flat amount.

• Commuting: a flat amount per kilometre of the one-way distance for each day you travel to work
• Working from home: a daily flat rate for days worked at home, up to an annual cap
• Work equipment: computers, tools, work clothing and professional literature
• Training and further education related to your job
• Job application costs and some moving costs for work
• Account maintenance fees, often accepted as a small flat amount
• Household services and tradespeople: a share of labour costs, paid by bank transfer
• Donations, church tax and certain insurance premiums as special expenses
• Medical costs above a personal threshold as extraordinary expenses

Documents to gather before you start

Collecting paperwork throughout the year makes filing much quicker. Keep a folder, paper or digital, and drop receipts in as they arrive. You usually do not need to send receipts with the return, but you must keep them and provide them if the tax office asks.

• Your tax ID (Steuer-ID) and, if you have filed before, your tax number (Steuernummer)
• Your annual wage tax certificate from your employer
• Certificates for benefits such as unemployment benefit or parental allowance
• Receipts and invoices for work-related costs
• Invoices for household services and tradespeople, with proof of bank payment
• Donation receipts and childcare invoices
• Annual statements from banks and brokers, if relevant

After you file: the tax assessment

The tax office checks your return and sends a tax assessment notice (Steuerbescheid). It shows the tax due for the year, what was already paid and whether you get a refund or must pay more. Refunds are transferred to the bank account you provided.

Compare the assessment with your return. If the office rejected something you believe is correct, you can file an objection (Einspruch) within one month of the notice being delivered. An objection is free and can be submitted in writing or electronically. Explain which point you dispute and include supporting documents.

Frequently asked questions

The basics of a tax return in Germany come down to a few habits: know whether you must file, note the deadline, keep receipts during the year and claim the deductions that apply to you. Check your assessment carefully and object within a month if something is wrong. For anything complex, a tax adviser or income tax help association is money well spent.
