Claire Buys from a German Autohaus: Understanding the VAT Margin Scheme Invoice

Why the invoice looked unusual

The Autohaus had originally bought Claire's C-Class from a private individual, meaning it could not reclaim input VAT on that purchase. To avoid taxing the full resale price twice, German (and EU-wide) VAT law lets dealers in this situation use the differenzbesteuerung, the margin scheme — known in Spain as REBU (Régimen Especial de Bienes Usados). Under this scheme, VAT is calculated only on the dealer's margin (selling price minus buying price), and that VAT is embedded within the final price rather than itemised as a separate line. This is why Claire's invoice showed a single all-in price with a note referencing the margin scheme rather than a conventional VAT breakdown.

Why this still counts as a professional sale for Spanish purposes

What determines ITP versus VAT in Spain is not whether VAT appears as a separate line item, but whether the seller is a VAT-registered professional dealer acting as such. A margin-scheme sale from a registered Autohaus is unambiguously a professional sale, so ITP does not apply to Claire's purchase, even though the invoice does not show a conventional itemised IVA figure. The invoice needed to state clearly that it was issued under the margin scheme (in Germany, referencing §25a UStG, or in Spain the equivalent REBU wording), which is the documentation Hacienda expects to see if the ITP-exempt status of the sale is ever questioned.

What Claire actually paid

The car was priced at 22,500 EUR all-in under the margin scheme. No ITP applied, saving Claire what would otherwise have been 900 to 1,800 EUR (4-8%) had this been treated as a private sale. IEDMT still applied, as it does regardless of seller type, based on the C-Class's CO2 figure of 156 g/km, placing it in the 4.75% band, calculated against a Hacienda table value of 20,500 EUR: 974 EUR. Add ITV (65 EUR), Certificate of Conformity (already held), and DGT registration and plates (120 EUR). Total tax and admin cost: 1,159 EUR, well below what an equivalent private-sale purchase would have cost once ITP was added.

The documentation Claire kept for her own protection

• The original Autohaus invoice with the margin-scheme reference clearly stated.
• The dealer's German business registration (Gewerbeanmeldung) and VAT ID, to demonstrate professional status if ever asked.
• A written confirmation from the dealer, in case the invoice wording alone was considered ambiguous by a Spanish gestor.
• The full purchase and payment trail showing the price paid matched the invoice exactly.

The mistake this avoids

Buyers who see a margin-scheme invoice with no itemised VAT sometimes assume, incorrectly, that it must have been a private sale and volunteer to pay ITP anyway out of caution, or conversely get flagged by a gestor unfamiliar with the scheme who assumes the same thing. Either way, the fix is the same: keep clear proof the seller is a VAT-registered professional business, regardless of how the VAT itself is presented on the invoice.

Frequently asked questions

Does the margin scheme change the IEDMT calculation?

No — IEDMT is calculated against the Hacienda table value and the car's CO2 figure, independent of how VAT was structured on the purchase invoice.

What if the gestor insists on treating it as a private sale?

Provide the dealer's VAT ID, business registration and the invoice's margin-scheme reference; this is standard, recognised documentation and a competent gestor experienced with EU imports should accept it without difficulty.

Is the margin scheme common among German used-car dealers?

Yes, it is the standard treatment whenever a dealer buys stock from private sellers and cannot reclaim input VAT on that purchase, which describes a large share of the used-car trade.
