Guides for online sellers
How do I file the advance VAT return?
You file the advance VAT return (Umsatzsteuervoranmeldung, UStVA) electronically and authenticated, for example in the Mein ELSTER portal. You register once, open "Formulare und Leistungen", choose the return and the calendar year, enter net amounts in whole euros and send. Filing and payment are due on the 10th day after the end of the reporting period at the latest.

You transmit the advance VAT return (Umsatzsteuer-Voranmeldung, UStVA) electronically via the official interface, by the 10th day after each month or quarter ends; the prepayment is due the same day. If that day is a Saturday, Sunday or public holiday, the deadline ends on the next working day. A permanent deadline extension (Dauerfristverlängerung) adds one month.

Have you started a trade or a freelance activity and need a tax number (Steuernummer)? You apply for it with the tax registration questionnaire (Fragebogen zur steuerlichen Erfassung). Since 1 January 2021 you must transmit it electronically to your tax office (Finanzamt), unprompted and within one month after you start. The tax number comes by post.

The EÜR is how you work out your profit: business income minus business expenses. You transmit it as the Anlage EÜR to the tax office (Finanzamt), for example in ELSTER, together with your income tax return. The deadline is in principle 31 July of the following year; for 2026 it is Monday, 2 August 2027 (31 July is a Saturday).

The OSS return is due every quarter: by 30 April, 31 July, 31 October and 31 January. Return and payment must have reached the Federal Central Tax Office (Bundeszentralamt für Steuern, BZSt) by then; you submit it only electronically in the BZStOnline Portal. This applies once your distance sales to other EU countries together exceed €10,000 net in the previous year or in the current year.

Do you sell on eBay as a business? Small business owners (Kleinunternehmer; previous year up to €25,000, current year up to €100,000) show no VAT and usually file no advance return. Otherwise you file quarterly or monthly by the 10th. Above €10,000 of sales to private customers in other EU countries, the destination country's VAT applies, usually via the OSS.
