What should you do if you forgot to file your tax return?

What happens if you submit your tax return late in Germany?


1. First step: clarify your status – were you obliged to file or not?

Situation Is it considered a real delay?
You were not obliged to file (voluntary filing) No problem – you have 4 years to file
You were legally obliged to file Yes – it is a delay and you must act quickly

1. File your tax return as soon as possible

Even if you have missed the official deadline, you should submit your tax return as soon as possible, for example via:

  • the official online portal ELSTER (free),

  • a tax advisor or a Lohnsteuerhilfeverein (wage tax assistance association),

  • or tax software / apps (e.g. Taxfix, WISO, Smartsteuer etc.).

Do not wait for a warning letter from the Finanzamt –
take the initiative and file voluntarily.


2. Possible consequences of filing late

Consequence When does it apply?
Verspätungszuschlag (late filing penalty) Penalty of up to 10 % of the tax due or at least €25 per month started
Schätzung der Steuer (estimated assessment) The Finanzamt may estimate your tax without your return – usually to your disadvantage
Zinsen (interest on arrears) 0.5 % per month on additional tax, starting 15 months after the end of the tax year
Mahnung / Zahlungsaufforderung (reminder / payment demand) Official reminder plus possible extra fees if you do not pay after an estimated assessment

3. Can you avoid or reduce penalties?

Yes, often partially or even completely, especially if:

  • you file your tax return before the Finanzamt sends an official reminder,

  • or you explain the delay in a short letter attached to your return
    (e.g. illness, moving house, family issues).

In such cases the Finanzamt can, at its discretion,
waive or reduce the late filing penalty.


Sample cover letter explaining the delay (in German)

You can attach this to your tax return – just replace the brackets:

Sehr geehrte Damen und Herren,

ich reiche hiermit verspätet meine Einkommensteuererklärung für das Jahr [xxxx] ein.

Der Grund für die Verzögerung war [z. B. Krankheit, Umzug, familiäre Umstände].

Ich bitte darum, von einem Verspätungszuschlag abzusehen.

Mit freundlichen Grüßen
[Ihr Name]
[Ihre Anschrift]
[Datum]


4. Maximum period for late filing

Type of filing Latest possible filing date
Obligatory filing (Pflichtveranlagung) Up to 3 years, but with increasing penalties and interest
Voluntary filing (Freiwillige Veranlagung) Up to 4 years after the end of the tax year

Example:

  • Tax return for 2020
    → voluntary filing still possible until 31 December 2024.
