§ 13b reverse-charge invoice: the required sentence and a subcontractor template
The sentence that must appear verbatim
§ 14a Abs. 5 UStG does not ask for a paraphrase, it asks for this wording. Put it clearly below the invoice total — a clause buried in body text is not enough.
Steuerschuldnerschaft des Leistungsempfängers (§ 13b Abs. 2 Nr. 4 i. V. m. Abs. 5 UStG). Die Umsatzsteuer schuldet der Leistungsempfänger.
The same paragraph carries the second half of the rule: for these invoices the separate VAT statement is not applied. So there is no VAT line, no 19 %, and no “0 % VAT” row either — the amount is simply not stated. Show VAT anyway and you owe the excess under § 14c Abs. 1 UStG, even though you never had to remit it in the first place.
The real test: not the job, but the recipient
This is the mistake that gets expensive. § 13b Abs. 2 Nr. 4 UStG does describe the service — construction work including supplies of work and other services connected with land that serve the creation, repair, maintenance, alteration or removal of structures. But whether the tax liability actually shifts is decided by Abs. 5, and that looks at your client: he must himself be a business that persistently provides such construction services.
- A main contractor hiring you as subcontractor: § 13b applies — he persistently provides construction services himself.
- A private client building a house: § 13b does not apply. You invoice with VAT.
- A company renovating its own office once: § 13b does not apply — it does not provide construction services, it commissions them.
- Planning and structural engineering: expressly excluded, even on the same project.
None of this is proven by gut feeling but on paper: the tax office issues the recipient certificate USt 1 TG, valid for up to 3 years. Ask to see it before the first invoice and keep a copy on file. The risk is asymmetric: leave VAT off wrongly and you owe it — and collecting it from the client afterwards rarely works.
Template: subcontractor to main contractor
Everything else stays an ordinary invoice under § 14 UStG — sequential number, service period, addresses, a customary description of the work. The only differences are the missing tax line and the note at the end.

Die Umsatzsteuer schuldet der Leistungsempfänger.For purely domestic cases the recipient VAT ID is not a mandatory item under § 14 Abs. 4 UStG — it is here anyway because, in a dispute, it evidences that you supplied a business acting as such. For intra-EU services it is mandatory regardless. More in the reverse-charge guide, which also covers the Austrian variant.
