A letter from the Finanzamt — what now?

You open the mailbox, pull out an official envelope, and there it is at the top: Finanzamt. Take a breath. Most letters from the German tax office are less scary than they look. But almost all of them carry a deadline. Here's how to handle yours.

What kind of letter is this?

The Finanzamt writes to you for a handful of reasons. Usually one of these five:

The type is in the subject line, top left. Something like "Bescheid für 2024 über Einkommensteuer" or just "Mahnung".

How the letter is typically structured

Every Finanzamt letter has more or less the same fields. Once you recognise them, you don't need a translator:

Steuernummer
Your personal number at the tax office, top right. Format: 12/345/67890. Not the same as the Steuer-ID (which has 11 digits).
Date, top right
This drives the deadline. The letter is officially considered delivered three days after this date — even if you only pull it out of the mailbox a week later.
Festsetzung
The result. A positive amount means you typically need to pay. A negative amount or "zu Ihren Gunsten" means you get a refund.
Fälligkeit
The due date — when the money has to land in the tax office's account. Usually a month for back-payments.
IBAN / bank details
The account to pay into (only on back-payments). Always use your Steuernummer as the reference — otherwise the payment vanishes into the void.
Rechtsbehelfsbelehrung
The fine-print paragraph at the bottom. It tells you that you have one month to file an objection.

Typical next steps to consider

Five steps. Work through them and the letter is sorted:

  1. Write the deadline down. Letter date + 3 days + 1 month. Pop it into your phone calendar with a reminder a week before.
  2. Check the details. Right name, right address, right tax number? Does the amount match what you expected? Have all your deductions been counted?
  3. Decide: agree or not? If it all looks right, just pay (or wait for the refund). If something is missing, wrong, or just feels off — file an objection.
  4. File an Einspruch (objection), if needed. It's informal. One sentence is enough: "Hiermit lege ich Einspruch gegen den Bescheid vom [date] ein, Steuernummer [...]." By letter, fax, or via ELSTER. The full justification can come within the next two weeks.
  5. Pay, or ask for time. If you owe money and have it: transfer it, done. If you can't manage it right now, write a short informal letter asking for Stundung (deferment) or Ratenzahlung (instalments). The tax office almost always says yes if you ask early.

The 3-day rule. Finanzamt letters are considered delivered in many cases around three days after the date at the top. Doesn't matter when you actually read it. Your objection period starts from that fictional delivery date. If you were on holiday for two weeks and only opened the letter when you got back, you've already lost two weeks of your window.

What can typically happen if there is no response

Ignoring it is the expensive option. What happens depends on the type of letter:

When is a Steuerberater worth it?

For a simple objection or a normal reminder, you don't need one. When it does make sense:

An initial consultation costs €100–200. Usually cheaper than signing something wrong.

Frequently asked questions

What happens if I just ignore a Finanzamt letter?

A tax assessment becomes final after one month, even if it's wrong. An unpaid back-payment gets a 1% surcharge per month, then enforcement — meaning bailiffs or account garnishment. An ignored information request leads the tax office to estimate your income, and you pay tax on the estimate.

How much time do I have to file an objection?

One month from delivery. Delivery means in many cases around three days after the date at the top of the letter. So if the letter is dated 5 March, it counts as delivered on 8 March, and your deadline is 8 April.

Do I need a tax advisor to file an objection?

No. An Einspruch is informal. One sentence — "Hiermit lege ich Einspruch gegen den Bescheid vom [date] ein, Steuernummer [...]" — is enough. You can send the full justification within two weeks.

I can't read the letter in German. What now?

Take a photo with the Postera app. You will typically get an English summary with the key points: deadline, amount, what to do.

How do I tell a tax assessment from a reminder?

Check the subject line, top left. "Bescheid über …" is a tax assessment (the first letter, with an objection window). "Mahnung" or "Zahlungserinnerung" means the debt is already overdue. You can't object to a Mahnung — only pay or apply for deferment.
