Trade Tax Return Germany 2026: Guide, Deadlines & Form GewSt 1 A

Once you register a business in Germany, there is no way around the trade tax return (Gewerbesteuererklärung). For sole proprietors, partnerships and every UG or GmbH it is an annual obligation – regardless of whether any trade tax is actually due. This guide shows who has to file, which deadlines apply in 2026 and how to complete form GewSt 1 A correctly.

The trade tax return is the basis on which the tax office sets your trade tax assessment amount (Gewerbesteuermessbetrag). Your municipality then multiplies this amount by its local multiplier (Hebesatz) – and that produces the tax you actually pay. You file the return with the tax office, but the assessment of the final amount comes from the municipality.

Two authorities and a stack of forms? At its core it is a single form – the GewSt 1 A annex – plus a couple of extra annexes if your business operates in more than one municipality. If your bookkeeping is clean, the return is usually done faster than most people fear.

Who Has to File a Trade Tax Return?

Trade tax – and therefore the obligation to file – applies to every standing commercial business in Germany. Specifically:

• Sole proprietors with a business registration
• Partnerships such as GbR, OHG and KG
• Corporations – UG (limited liability) and GmbH by legal form

Exempt are pure freelancers under § 18 EStG (e.g. doctors, lawyers, designers, developers), farmers and pure asset management. Whether you count as a freelancer or a trader is not always obvious – more on that in our guide to the business registration in Germany.

Important for GmbH and UG: there is no exemption threshold here. Sole proprietors and partnerships, by contrast, keep the first €24,500 of trade income tax-free each year. If your trade income is below that, you pay no trade tax – but as a trader you must still file the return once the tax office asks you to.

Deadlines for the 2026 Trade Tax Return

The trade tax return follows the same deadlines as the other annual tax returns:

• Without a tax advisor: for the 2025 year by 31 July 2026 at the latest.
• With a tax advisor: extended to the end of February 2027 (the last day of February in the year after next).

File late and you risk a late-filing penalty of at least €25 per month started. If you can foresee that you won't be ready in time, apply for a deadline extension with the tax office before the deadline passes.

What Documents You Need

The trade tax return is built entirely on your profit determination. You'll need:

• your profit – as an EÜR (sole proprietors/partnerships) or from the balance sheet (GmbH/UG)
• schedules for add-backs under § 8 GewStG (interest, rent, lease payments, licences)
• supporting documents for deductions under § 9 GewStG (e.g. business real estate)
• any carried-forward trade loss from prior years

The cleaner your ongoing bookkeeping, the faster you complete the annex. AI-powered bookkeeping assigns receipts to the right accounts automatically – the basis for an error-free return.

Step by Step Through Form GewSt 1 A

The central return is form GewSt 1 A. Complete it in this order:

1. General information – business, tax office, municipality, assessment period.
2. Profit from the trade business – taken from the EÜR or balance sheet.
3. Add-backs (§ 8 GewStG) – 25% of certain financing components, to the extent they exceed the €200,000 allowance.
4. Deductions (§ 9 GewStG) – including 1.2% of the assessed value of your own business real estate.
5. Trade loss – offset of a carried-forward loss from prior years.
6. Apportionment – only for permanent establishments in several municipalities; this additionally requires form GewSt 1 D.

Filing is done electronically and authenticated via ELSTER – paper submission is no longer permitted for traders.

Calculating Trade Tax: Assessment Amount and Multiplier

The calculation runs in three stages:

1. Determine the trade income (profit + add-backs − deductions), round down to the nearest €100, and for individuals subtract the €24,500 allowance.
2. Multiply the result by the assessment rate of 3.5% → this is the trade tax assessment amount.
3. Multiply the assessment amount by the municipal multiplier (Hebesatz) → the trade tax due.

Multipliers vary widely: Berlin is at 410%, Hamburg at 470%, Munich at 490%, and the statutory minimum is 200%. Example for a GmbH: €60,000 trade income × 3.5% = €2,100 assessment amount; at a 410% multiplier that gives €8,610 in trade tax. How the prepayments arise is explained in Trade Tax for GmbH and UG.

Credit Against Income Tax (§ 35 EStG)

Sole proprietors and partners in partnerships don't pay trade tax twice: under § 35 EStG, 4.0 times the trade tax assessment amount is credited against income tax – but no more than the trade tax actually paid. In municipalities with a multiplier up to around 400%, this effectively neutralises the trade tax entirely.

For GmbH and UG this credit does not apply – here trade tax remains a genuine extra burden alongside corporate income tax. For the other returns a corporation has to file, see the GmbH tax return.

Common Mistakes

• Forgetting add-backs: interest, rent and lease payments are often left out – the tax office recalculates them later.
• Not filing despite a loss: the obligation exists regardless of the result.
• Applying the allowance incorrectly: the €24,500 applies only to individuals, never to a UG/GmbH.
• Missing the deadline: the late-filing penalty is applied automatically.

Conclusion

The trade tax return is mandatory for every trader – from sole proprietor to GmbH. With a clean profit determination, correctly recorded add-backs and electronic filing via ELSTER, it is well manageable. Norman keeps your bookkeeping running all year and prepares your tax returns automatically – so the assessment amount, deadlines and annexes are no longer a source of stress at year-end.
