Invoice corrections and cancellation invoices explained

If an invoice has not yet been sent to the customer, you can simply correct the draft. Once it has been sent, do not overwrite or delete the original. Create a traceable document that refers clearly to it. The right method depends on whether an invoice detail was wrong, the price changed later, or the supply was cancelled completely.

The key distinction under German law is this: an invoice correction (Rechnungskorrektur) fixes missing or incorrect information. A cancellation invoice (Stornorechnung) reverses the original invoice in full, normally by using opposite signs. If the supply still stands, a new correct invoice follows. Incorrect or unauthorised VAT requires additional steps.

Rule of thumb: retain the original, create a new correction document, identify the original invoice unambiguously, inform the customer, and adjust the accounting entry or payment accordingly.

Invoice correction, cancellation invoice, or price adjustment?

• Correction under section 31(5) UStDV: required information is missing or incorrect, but the underlying transaction remains valid—for example, an incorrect address, supply date, description, or calculation.
• Cancellation invoice: a new document reverses the entire original invoice with negative amounts. If the supply remains billable, issue a new invoice afterwards.
• Change in the taxable amount under section 17 UStG: a discount, return, price reduction, or cancellation changes the consideration after the event. Output VAT and input VAT may need adjustment in the period in which the change occurs.
• Incorrect or unauthorised VAT under section 14c UStG: showing too much VAT or VAT without entitlement cannot be repaired by quietly editing a PDF. The issuer may owe the amount shown until an effective correction is made.

The substance of the transaction matters more than the heading printed on the document.

Which method fits which error?

• Not sent yet: correct the draft and send only the correct version.
• One required detail is missing or wrong: a correction document may be sufficient if it refers specifically and unambiguously to the original.
• Amount, VAT rate, or the whole calculation is wrong: a full cancellation invoice followed by a new invoice is often the clearest route.
• The supply is cancelled completely: reverse the invoice, refund or offset the payment, and review the tax entries.
• The price is reduced later: document the price reduction and apply section 17 UStG where relevant.
• VAT was shown without entitlement: involve a tax adviser, especially under the German VAT exemption scheme for small businesses (Kleinunternehmerregelung).

A typo that does not affect required information, the parties, the supply, the consideration, or VAT may be less serious. The customer’s copy and your records should still agree.

How to make a targeted invoice correction

Section 31(5) UStDV permits the issuer to transmit only the missing or incorrect information. Together with the original invoice, the correction must remain clear and verifiable.

A useful correction document includes:

• “Correction to invoice …” or similarly clear wording;
• the number and date of the original invoice;
• the issuer’s name and address;
• the correction date;
• the old and corrected information, or an unmistakable description of the change;
• traceable net, VAT, and gross amounts where figures change;
• confirmation that the other parts of the original remain unchanged.

The German VAT Application Decree states that a separate new invoice number is not required for a targeted correction document. A full replacement invoice should have its own unique number and refer clearly to the cancelled original. The customer cannot make a legally effective correction unilaterally; the issuer normally makes it.

How to issue a full cancellation invoice

A cancellation invoice mirrors the original. Line items, net amount, VAT, and gross amount appear with opposite signs so that the original accounting entry is neutralised.

1. Preserve the original invoice and prevent silent changes.
2. Create a new accounting document with its own number and the current issue date.
3. State the original invoice number, original date, and reason for cancellation.
4. Copy all affected items with opposite signs.
5. Confirm that net, VAT, and gross totals offset the original exactly.
6. Send the cancellation invoice to the customer.
7. If the supply remains valid, issue a new correct invoice.
8. Match the payment, refund, or offset to both the original and the cancellation.

Do not delete the original or reuse its number. Keep the original, cancellation, and replacement linked.

VAT cases that need special care

If an invoice shows more VAT than was legally due, section 14c(1) UStG generally makes the issuer liable for the excess. The correction must be made towards the customer; an internal edit alone is not enough.

If VAT was shown although the issuer was not entitled to show it, section 14c(2) UStG applies. The risk to tax revenue must be removed, and the statute provides for a separate written application and approval by the tax office before the tax liability can be corrected. This can affect a small business using the Kleinunternehmerregelung and belongs with a tax adviser.

If a VAT return has already been filed, clarify the correct tax period for the invoice correction, price adjustment, or cancellation. Never backdate a document.

Do not use credit note automatically as a synonym for a cancellation invoice. In German VAT law, Gutschrift primarily means self-billing: an invoice issued by the customer for the supplier under a prior agreement. A commercial credit or cancellation document is different.

Correcting e-invoices in 2026

Since 1 January 2025, German businesses generally need to be able to receive e-invoices. Transitional rules apply to issuing them. Until the end of 2026, a transaction completed by then can generally still be invoiced on paper or, with the recipient’s consent, in another electronic format.

Where an e-invoice is already mandatory for the transaction, the Federal Ministry of Finance states that the correction must also be an e-invoice using an appropriate correction type. XRechnung and ZUGFeRD are common structured formats. The correction data must refer specifically and unambiguously to the original e-invoice.

Do not retain only a PDF view. Keep the structured original data, the correction, and any replacement invoice available, readable, and machine-processable.

A practical seven-step workflow

1. Classify the issue: wrong required detail, changed price, cancelled supply, or incorrect VAT?
2. Preserve the original: never overwrite, delete, or reissue a sent invoice under the same number.
3. Choose the document: targeted correction, full cancellation invoice, or price-adjustment document.
4. Create the link: state the original number and date.
5. Validate the content: parties, supply date, description, net, VAT rate, VAT amount, and gross.
6. Send and account for it: the customer receives the document; update the unpaid invoice, payment, refund, and VAT records.
7. Retain the chain: keep the original, correction, replacement, and relevant communication linked.

In Motorica, you can cancel an invoice from the invoice overview and record the reason. Then check the generated document, payment, and any new invoice. The software supports the workflow but does not replace individual tax advice.

Checklist before sending

• Is this a wrong detail, a partial price change, or a full cancellation?
• Does the original remain unchanged in the records?
• Does the new document identify the original number and date?
• Is the correction or cancellation reason clear?
• Are net, VAT rate, VAT amount, and gross mathematically correct?
• Do cancellation amounts have the right signs?
• Is a new invoice needed because the supply still stands?
• Are payment, refund, or offset matched correctly?
• Was the document actually sent to the customer?
• Are structured e-invoice data and correction retained?
• Is a tax adviser involved for section 14c UStG or already reported VAT?

Common mistakes and better solutions

• Overwriting the original: create a separate correction document instead.
• Using one invoice number for two full invoices: give the replacement a new unique number and link it to the cancellation.
• Cancelling only internally: send the correction to the customer and document delivery.
• Issuing a negative document without a reference: add the original number, date, and reason.
• Calling every negative document a credit note: use the correct term—cancellation invoice, invoice correction, or price reduction.
• Saving only the e-invoice PDF: retain the structured source and correction data.
• Assuming foreign-language invoices are prohibited: there is no blanket German-only rule, but the tax authority may request a German translation under section 87 AO.

Frequently asked questions

Can I simply edit an invoice after sending it?

No. Retain the version sent and create a new correction document that can be linked to it unambiguously.

Does an invoice correction need a new invoice number?

A targeted correction document does not necessarily need a new invoice number if it clearly identifies the original. A full replacement invoice should have its own unique number.

Must I always cancel and reissue?

No. A correction document can be enough for individual missing or incorrect details. Cancellation plus a new invoice is often clearer where the totals or the entire invoice are wrong.

What if the customer has already paid?

The correction does not alter the payment automatically. Record whether you refund, collect the difference, or offset it against a new invoice.

How long must I retain the original and correction?

Businesses must generally retain issued and received invoices for eight years, starting at the end of the calendar year in which the invoice was issued. Other records or special cases can have different periods.

Must an invoice be in German?

There is no general rule requiring every invoice to be issued only in German. The tax authority may, however, request a translation and, in justified cases, a qualified translation.

Conclusion

A proper correction preserves the complete history: original, correction or cancellation, any replacement invoice, and payment. A targeted correction may be enough for a single required detail. A full cancellation invoice with opposite amounts is clearer when the whole invoice must be reversed. VAT errors, filed returns, and e-invoices require extra care.
