Margin Taxation Invoice – Requirements, Template & Common Mistakes

The invoice with margin taxation is a central document in the used car trade – and at the same time a frequent source of errors. Unlike standard taxation, invoices under §25a UStG are subject to special regulations: the VAT must not be shown separately, and a specific reference to margin taxation is mandatory. Errors in invoicing can quickly lead to a tax liability under §14c UStG – even if the buyer has no input tax deduction.

In this guide, you will learn which mandatory details must appear on an invoice with margin taxation, which details are expressly prohibited, and what a correct invoice looks like in practice. Additionally, we will show you the most common mistakes and how to avoid them with the right software.

Legal basis: §25a para. 4 UStG and the invoicing requirements

The legal requirements for an invoice with margin taxation arise from the interplay of several provisions of the VAT Act. The central provision is §25a para. 4 UStG, which contains a clear prohibition:

§25a para. 4 UStG: „If the tax is calculated on the agreed consideration under margin taxation, it must be calculated for the tax period in which the consideration was received. The tax must not be shown separately on the invoice.“

In addition, the general invoicing requirements of §14 para. 4 UStG apply, adapted for the specifics of margin taxation. Section 25a.1 para. 9 UStAE (VAT Application Decree) specifies that the invoice must contain a reference to the application of the special regulation.

Additionally, the EU VAT System Directive (Art. 226 No. 14 VAT System Directive) is relevant: according to this, the invoice must contain a reference to the applied special regulation. In Germany, this is typically fulfilled by the notation „margin taxation pursuant to §25a UStG“.

Mandatory details on the invoice with margin taxation

A margin taxation invoice must contain certain details to comply with both the general invoicing requirements and the special requirements of §25a UStG. Below you will find an overview of all mandatory details.

General mandatory details pursuant to §14 para. 4 UStG

• Full name and address of the supplying entrepreneur (dealer)
• Full name and address of the recipient (buyer)
• Tax number or VAT identification number of the dealer
• Invoice date (date of issue)
• Sequential, uniquely assigned invoice number
• Quantity and type of goods delivered – for vehicle sales: make, model, VIN, first registration, mileage
• Date of delivery or service (may coincide with invoice date)
• Total amount (gross selling price)

Special mandatory details for margin taxation

In addition to the general details, the invoice must contain a clear reference to the application of margin taxation. The tax authorities accept various wordings:

• „Margin taxation pursuant to §25a UStG“
• „Used goods / special regulation – margin taxation pursuant to §25a UStG“
• „Margin taxation pursuant to §25a UStG – VAT is not shown separately“

Recommendation: Always use the detailed version: „Margin taxation pursuant to §25a UStG – VAT is included in the invoice amount but is not shown separately.“ This wording is legally unambiguous and avoids queries during tax audits.

What must NOT appear on the invoice

Equally important as the mandatory details is knowing what must absolutely not appear on an invoice with margin taxation. Incorrect details can have serious tax consequences.

Consequence of incorrect tax disclosure: §14c UStG

If VAT is shown separately on an invoice with margin taxation – whether accidentally or intentionally – §14c para. 1 UStG applies. The consequence is severe:

• The dealer owes the disclosed tax amount to the tax office – in addition to the margin tax on the difference.
• The buyer nevertheless has no input tax deduction, as margin taxation was applied.
• A correction is possible (§14c para. 1 sentence 2 UStG in conjunction with §17 para. 1 UStG), but requires a corrected invoice to the buyer and repayment of the incorrectly disclosed amount.

Practical example: A car dealer sells a used car for 10,500 € with margin taxation but accidentally discloses „incl. 19 % VAT = 1,676.47 €“ on the invoice. Result: they owe the tax office an additional 1,676.47 € under §14c UStG – in addition to the margin tax of 399.16 € already due on the margin.

Difference: Invoice with margin taxation vs. standard taxation

To better understand the specifics of a margin taxation invoice, a direct comparison with a regular invoice is helpful. The following differences are crucial:

Sample invoice with margin taxation – template

The following template shows what a correct invoice with margin taxation should look like in the used car trade. All mandatory details are included, and the tax disclosure is deliberately omitted.

Important: Note that the invoice shows no net amount, no tax rate, and no tax amount. Only the gross total amount is disclosed. The reference to margin taxation is placed at the end of the invoice as a mandatory detail.

Common mistakes on invoices with margin taxation

In our practice, we consistently see the same mistakes on margin taxation invoices. Each one can lead to back payments and penalties during a tax audit.

Mistake 1: Separate VAT disclosure

The most common and most serious mistake: the invoice shows a line such as „plus 19 % VAT“ or a separate VAT amount. This immediately triggers a tax liability under §14c UStG – in addition to the margin tax.

Mistake 2: Missing reference to margin taxation

Without the reference „margin taxation pursuant to §25a UStG“, the invoice is formally defective. This can lead the tax authorities during an audit to question the application of margin taxation and impose retroactive taxation on the full selling price.

Mistake 3: Stating „0 % VAT“ or „VAT-exempt“

Some dealers note „0 % VAT“ or „VAT-exempt delivery“ on the invoice. This is incorrect. The delivery is not tax-exempt – the tax is included in the margin but is not shown. The correct wording refers exclusively to §25a UStG.

Mistake 4: Net-gross breakdown

A breakdown into „net amount“ and „gross amount“ suggests to the reader that VAT was calculated separately. Even if no specific tax amount is mentioned, this presentation can be problematic. State only the total amount.

Mistake 5: Mixing standard and margin taxation on one invoice

If both margin-taxed and standard-taxed items appear on one invoice, a clear separation must be recognizable. In practice, it is recommended to create separate invoices for margin-taxed and standard-taxed transactions. Learn more about correct accounting in our article on booking margin taxation.

Mistake 6: Missing or incomplete vehicle data

Especially in the automotive trade, a precise description of the vehicle (make, model, VIN, mileage, first registration) is essential. Missing details can complicate the assignment of the transaction and cause problems during audits.

E-invoicing and margin taxation from 2025

With the e-invoicing mandate that has been in effect since January 1, 2025 for domestic B2B transactions, new requirements also arise for margin taxation. Invoices must be issued in a structured electronic format (XRechnung or ZUGFeRD).

Special considerations for e-invoices with margin taxation

• In the XML format, the tax exemption code VATEX-EU-AE (reverse charge / special regulation) must be used to identify margin taxation.
• The tax rate is stated as 0 % in the structured data set – this is correct in the XML context and does not correspond to the prohibited disclosure on the visual invoice.
• An additional free-text reference to §25a UStG is also required in the e-invoice.
• The transition periods for small businesses and companies with annual revenue below 800,000 € apply until the end of 2027.

Detailed information on implementation can be found on our page about e-invoicing for car dealers.
