Income tax return for Amazon and eBay sellers with VAT GPT

As an Amazon or eBay seller using the EÜR, you file the main form, the Anlage G for trade income and the Anlage EÜR for your profit. In VAT GPT you fill in the main form and the Anlage G in the menu "Income Tax" and create the EÜR on the "Taxes" page; with VAT GPT Pro you send both through ELSTER.

Only VAT GPT sends all three returns itself. Of the tools we compare, according to the providers' own pages (checked 3 November 2026), only VAT GPT submits the OSS return itself to the BZSt, plus the VAT advance return and the annual VAT return via ELSTER to the tax office, calculated from your Amazon and eBay reports. You do not have to go into Mein ELSTER or the BZStOnline portal yourself. With the others, you upload the OSS file in the BZStOnline portal yourself, or a tax adviser or the provider's service files it for you. Sending needs Pro. OSS software compared

In brief

Forms: main form, Anlage G and Anlage EÜR (ELSTER form ESt 1 A).
Where: in the menu "Income Tax", where you choose "Tradesperson" as your type of income.
Sending: "Preview report" and "Submit to Finanzamt" are Pro functions; you send the EÜR on the "Taxes" page in the "Profit & Loss Statement (Anlage EÜR)" area through "Review & Submit".

What are the steps in VAT GPT?

Create the EÜR: You upload reports under "Income & OSS" and invoices under "Expenses". How the EÜR arises from them is in Amazon EÜR: booking income and expenses correctly.
Open the wizard: In the menu "Income Tax" the income tax return asks "Which types of income apply to you?". You choose "Tradesperson".
Fill in the Anlage G: VAT GPT tells you there: enter your income from trade or business here. You enter the profit and check it against your EÜR. The fields are explained in Filling in the Anlage G.
Enter the trade tax base amount: For the tax reduction under section 35 EStG the Anlage G has the fields for the trade tax base amount and the municipality's multiplier (in percent). You take the base amount from your trade tax assessment notice.
Send: "Preview report" shows you the return, "Submit to Finanzamt" transmits it through ELSTER. You send the Anlage EÜR on the "Taxes" page in the "Profit & Loss Statement (Anlage EÜR)" area through "Review & Submit".

What do you enter and check yourself?

Personal details: name, tax number and tax office.
Profit in the Anlage G: It comes from your EÜR; you enter it and compare both figures.
Other income: for example wages, if you are employed. You choose the types of income that apply to you.
Special expenses and provisions: according to your documents.
Trade tax base amount: from your assessment notice.

What this means for you: you enter personal details, the profit from your EÜR and your other income yourself, and VAT GPT shows the fields.

By when do you file, and what applies to prepayments?

Without a tax adviser the deadline is seven months after the end of the calendar year (section 149 (2) AO). For 2026 that would be July 31, 2027, a Saturday; the deadline then ends on Monday, August 2, 2027 (section 108 (3) AO). All deadlines and the consequences of filing late are in Income tax return for the self-employed: deadline and filing.

Income tax prepayments are due on March 10, June 10, September 10 and December 10 (section 37 (1) EStG). The tax office sets them by notice. How to adjust them to your expected profit is in Adjust your income tax prepayments.

You transmit the return electronically if you have income from trade or business, with the statutory exceptions (section 25 (4) EStG).

What this means for you: file by 2 August 2027 for 2026 without a tax adviser, and watch the four prepayment dates.

Frequently asked questions

How do trade tax and income tax connect? For income from trade or business, income tax can be reduced by four times the trade tax base amount (section 35 EStG). The conditions and limits are in the statute; the Anlage G has its own fields for it.

Do I send the EÜR separately? Yes. The EÜR is transmitted electronically in the officially prescribed data format; on application the tax authority can waive this to avoid undue hardship (section 60 (4) EStDV). In VAT GPT you send it on the "Taxes" page in the "Profit & Loss Statement (Anlage EÜR)" area through "Review & Submit".

Can I create the 2026 return in 2026? The return covers the past calendar year. In 2026 you work on 2025.
