How does VAT filing frequency work in Germany?
The filing frequency depends on your previous year VAT liability: monthly if over EUR 7,500, quarterly if between EUR 1,000 and EUR 7,500, and annual if under EUR 1,000. In the first two years of business, monthly filing (monatliche Umsatzsteuer-Voranmeldung) is mandatory regardless of amount.
What is the Umsatzsteuer-Voranmeldung?
The Umsatzsteuer-Voranmeldung (USt-VA) is a periodic VAT return filed via ELSTER. It reports your output VAT (charged to customers) and input VAT (paid on purchases). The difference is either paid to or refunded by the Finanzamt. The return is due by the 10th of the following month (with possible Dauerfristverlängerung giving an extra month).
Can I switch between Kleinunternehmer and regular VAT?
You can voluntarily opt out of Kleinunternehmerregelung at any time, but you are then bound to regular VAT for 5 calendar years. After the binding period, you can return to Kleinunternehmer status if you meet the thresholds. Switching should be carefully considered based on your client base and input VAT situation.

When you must register, the process, and the Kleinunternehmerregelung option
When must you register for VAT?
All businesses must register with the Finanzamt when starting operations. If your turnover was above €22,000 last year or will exceed €50,000 this year, you must charge VAT. Below these thresholds, you can choose the Kleinunternehmerregelung and skip VAT. Registration happens through the Fragebogen zur steuerlichen Erfassung within 4 weeks of starting.
How do you register?
Complete the Fragebogen zur steuerlichen Erfassung via ELSTER (the Finanzamt online portal). The form asks about your business type, expected turnover, bank details, and whether you want to use the Kleinunternehmerregelung. The Finanzamt assigns your Steuernummer within 2-4 weeks. For an EU VAT number (USt-IdNr), apply separately at the BZSt.
What obligations come with VAT registration?
Once VAT-registered, you must: charge VAT on all invoices, file regular Umsatzsteuervoranmeldungen (monthly or quarterly), pay collected VAT to the Finanzamt, keep all invoices for 10 years, and file an annual Umsatzsteuerjahreserklärung. In your first two business years, monthly filing is mandatory regardless of turnover.
What is the Dauerfristverlängerung?
The Dauerfristverlängerung gives you one extra month to file your VAT return. Instead of filing by the 10th of the following month, you file by the 10th of the month after that. To get it, apply once at the Finanzamt and pay a Sondervorauszahlung of 1/11 of the previous year VAT. This is very common and highly recommended to avoid rushed filings.
Should you voluntarily register for VAT or use the Kleinunternehmerregelung?
Register voluntarily if: you sell mainly to businesses (they reclaim your VAT), you have high purchase costs (you can reclaim Vorsteuer), or you want to appear more professional. Use Kleinunternehmer if: you sell mainly to private consumers, have low expenses, and value simplicity. Once you opt for regular VAT, you are bound for 5 years.
What happens if you charge VAT without being registered?
If you show VAT on an invoice, you owe it to the Finanzamt even if you are not registered or using the Kleinunternehmerregelung — this is the Steuerschuldnerschaft nach §14c UStG. Your customer can claim the Vorsteuer, but you must pay the tax. This is a common and costly mistake. Always verify your VAT status before issuing invoices.
