Frequently Asked Questions
What VAT rate should I use as a German Kleinunternehmer?
If you qualify under §19 UStG, you are exempt from charging VAT — set the tax rate to 0 and add the note "Kein Ausweis von Umsatzsteuer, da Kleinunternehmer gemäß §19 UStG" to your invoice. Once your annual revenue exceeds €22,000 the exemption lapses and you must charge the standard 19% (or 7% for reduced-rate goods and services).
Is the discount applied before or after tax?
Before tax. The calculator subtracts your discount from the subtotal first, then applies the tax rate to the reduced amount. This is standard EU practice: VAT is charged on the actual consideration received, not the list price.
What if my client is subject to reverse-charge VAT for B2B EU cross-border work?
Set the tax rate to 0. Under the EU reverse-charge mechanism (§13b UStG in Germany), you issue a net invoice and your client accounts for VAT in their own country. Add the mandatory note "Steuerschuldnerschaft des Leistungsempfängers" to the invoice.
Can I calculate multiple line items at once?
This calculator handles one hours-based line item at a time. For multi-line invoices, run it once per line item and sum the totals manually, or use a full invoicing tool that accepts mixed rate types in a single document.
