How to Appeal a German Tax Assessment (Einspruch)

Your German tax assessment (Steuerbescheid) is wrong – work-related expenses cut, a receipt overlooked, a transposed digit in your income. The good news: you are not stuck with it. The Einspruch (objection) is informal, involves no fee, and succeeds in most situations. You just need to know the deadline, pick the right route, and avoid a few traps.

In short: You have one month from delivery to object (§ 355 AO). The Einspruch is informal and carries no fee – by letter, fax, or through ELSTER (Germany’s official online tax-filing portal). A justification is not required immediately. But note: the Finanzamt (German tax office) reviews the entire assessment and may change it to your disadvantage (Verböserung, § 367 (2) AO) – though you can withdraw the objection if that happens.

When an appeal is worth it

Not every assessment that hurts is wrong. An objection makes sense when one of these applies:

• A concrete error: the Finanzamt cut costs, failed to record receipts, or miscalculated. The most common and most promising situation.
• Missing proof you now have: you can submit receipts that were not available when you filed.
• Pending model proceedings (Musterverfahren): a legal question that also affects you is before the Federal Fiscal Court (Bundesfinanzhof) or the Federal Constitutional Court. Your objection can then be paused (§ 363 AO) until those proceedings are decided, and you benefit automatically.

Before you object, read the assessment carefully. Our guide on how to check your German tax assessment shows you which lines and explanations matter.

The deadline: one month, but from when exactly?

The objection deadline is one month from delivery of the assessment (§ 355 (1) AO). The key question is when an assessment counts as “delivered”:

• Four-day rule (§ 122 (2) AO): a posted assessment is deemed delivered on the fourth day after the date printed on it – regardless of when it actually arrived.
• Weekend shift (§ 108 (3) AO): if that fourth day is a Saturday, Sunday or public holiday, it moves to the next working day. The same applies to the end of the deadline.

Worked example: the assessment is dated Tuesday, 3 March 2026. Four days later would be Saturday, 7 March, so the assessment is deemed delivered on Monday, 9 March 2026. The one-month deadline ends at the close of 9 April 2026. Your objection must have reached the Finanzamt by then – not just been sent.

Important: if you miss the deadline, the assessment becomes final (bestandskräftig) and can only be corrected in narrow exceptions. So file a deadline-preserving objection and submit the reasons later, rather than letting the deadline pass.

How to appeal a German tax assessment: filing the Einspruch

An objection needs no special form, no lawyer, and no fee. You have three routes:

1. Through ELSTER – electronically, with confirmation of receipt. The cleanest option, because delivery is documented.
2. By letter or fax – to the Finanzamt that issued the assessment. For tight deadlines, use a traceable method.
3. In person – declared and recorded at the Finanzamt (zur Niederschrift).

A phone call is not enough: the objection must be in writing or electronic. Include:

• your name and tax number (Steuernummer) – at the top of the assessment
• the name of the assessment and its date (e.g. “income tax assessment 2025 dated 3 March 2026”)
• the clear statement: “I hereby file an objection.”
• optionally the reasons – or a note that you will submit them
• your signature (for a letter)

Sample wording

“Dear Sir or Madam, I hereby file an objection (Einspruch) against the income tax assessment 2025 dated 3 March 2026 (tax number …). I will submit the reasons within two weeks. Kind regards …”

That is enough to meet the deadline. The substance – for example proof of cut work-related expenses – can follow calmly.

Paying while the objection is pending: suspension of execution

A common misunderstanding: filing an objection does not delay payment. The objection has no suspensive effect – the back-payment (Nachzahlung) stays due on its date.

To delay payment, you must separately apply for a suspension of execution (Aussetzung der Vollziehung, AdV) under § 361 AO. The Finanzamt grants it when there are serious doubts about the assessment’s legality. Beware: if the AdV is granted and you ultimately lose, interest of 0.5% per month applies – 6% per year (§ 237 in conjunction with § 238 AO). So apply for AdV only when your objection has good prospects.

The risk of a worse result – and how to avoid it

The point many people miss: an objection opens the entire assessment for review. The Finanzamt may change it not only in your favour but also against you. This is called Verböserung (§ 367 (2) AO).

Example: you object over €300 of donations the office refused. During the review, it notices it had wrongly accepted €800 of work-related expenses. On balance, you could end up worse off than before.

The safeguard: the Finanzamt must expressly warn you before a worse result and give you a chance to respond. At that point you can withdraw your objection (§ 362 AO) – the original assessment then stands, and the threatened worsening does not take effect.

Einspruch or simple amendment request?

If you only want to correct one clear point and want to avoid the Verböserung risk, there is an alternative: the simple amendment request (schlichter Änderungsantrag) under § 172 (1) sentence 1 no. 2 (a) AO. It has the same one-month deadline.

Feature	Einspruch (§ 347 AO)	Amendment request (§ 172 AO)
Deadline	1 month from delivery	1 month from delivery
Scope of review	whole assessment	only the named point
Worse result possible	yes	no
Pause for model proceedings	yes (§ 363 AO)	no
Cost	none	none

Rule of thumb: a clearly limited transposed digit can be fixed with a low-risk amendment request. For several disputed points or pending model proceedings, the objection is the right route.

What happens after you file

Once your objection arrives, the Finanzamt reviews again. There are two outcomes:

• Abhilfe (remedy): the Finanzamt agrees fully or partly and issues an amended assessment. Most well-founded objections end here.
• Einspruchsentscheidung (objection ruling): if the office holds its view, it issues a formal ruling with reasons and instructions on further remedies. That ends the out-of-court stage.

Against a rejecting ruling, you can file a lawsuit at the tax court (Finanzgericht) within one month (§ 47 FGO). Unlike the objection, a lawsuit carries court fees and possibly advisor costs. For most disputes, the objection therefore stays the decisive, low-risk tool. More on typical disputed costs is on our pages for employees and for freelancers.

A worked example

Lena is employed and claimed €2,400 of work-related expenses: €900 training, €700 equipment, €800 commuting. The assessment only grants the employee lump sum of €1,230. The explanations say: “training costs could not be considered for lack of proof.”

Lena objects and submits the invoice and payment record for the training. The Finanzamt remedies and accepts the full €2,400. The extra €1,170 lowers her taxable income; at a marginal rate of about 30%, that means roughly €350 more refund – for one informal letter.

How Restio helps

An appeal rarely fails on the law – it fails on the deadline and the wording. That is exactly where Restio steps in:
