Kleinunternehmer checker

Enter net revenue and check whether you can use the Kleinunternehmer rule under § 19 UStG — with threshold check and invoice note.

Enter all revenue net — without VAT, as on your invoice before VAT.

Optional — for a full-year projection (YTD + remaining).

General information only — not legal or tax advice. Tax and e-invoice rules can change; the applicable laws control (e.g. § 19 UStG, § 14 UStG). Confirm with a tax advisor or lawyer if unsure.

Kleinunternehmer rule under § 19 UStG — thresholds since 2025

The Kleinunternehmer rule lets many self-employed people invoice without VAT — if statutory revenue thresholds are met. Since the 2024 Annual Tax Act, limits are net and the current-year fallbeil is stricter.

Two thresholds from year two

  1. Prior-year revenue may be at most 25.000,00 € net.
  2. Current year may be at most 100.000,00 € net (fallbeil — exceeding ends the rule immediately).

In the founding year there is no prior-year revenue. What matters is that founding-year revenue does not exceed 25.000,00 € net.

Example: prior year €18,000, current year €30,000 expected

  • Prior year: 18.000,00 € — under 25.000,00 € ✓
  • YTD 12.000,00 € + remaining 18.000,00 € = 30.000,00 € — under 100.000,00 € ✓
  • Result: Kleinunternehmer rule likely available.

Invoice note: “Gemäß § 19 UStG wird keine Umsatzsteuer berechnet.”

FAQ

Which revenue thresholds apply for Kleinunternehmer since 2025?
Under the 2024 Annual Tax Act (net): founding year at most €25,000. From year two, prior-year revenue at most €25,000 and current-year revenue at most €100,000 (fallbeil threshold).
What does the €100,000 fallbeil mean?
If current-calendar-year net revenue exceeds €100,000, Kleinunternehmer status ends immediately. The excess is subject to regular VAT — not only from the next year.
Should I enter net or gross revenue?
Thresholds use net revenue — without VAT shown. Enter the amounts you invoice before VAT.
What note belongs on a Kleinunternehmer invoice?
Typically: “Gemäß § 19 UStG wird keine Umsatzsteuer berechnet.” Without this note the tax office may assess VAT even if you qualify.
What happens if I exceed the threshold?
Exceeding €100,000 in the current year: regular VAT on the excess immediately. Prior-year revenue above €25,000 net: usually no Kleinunternehmer rule in the current year.
