Book NowMost e-invoice mistakes are straightforward to fix, but the correct treatment depends on what changed. In Germany, a wrong VAT amount or missing invoice information may require a formal correction that clearly refers to the original invoice. A later discount, rebate or price reduction is different and may instead require an adjustment under §17 UStG.
This article focuses on B2B e-invoicing in Germany. B2G invoices are subject to separate requirements and processes and are therefore outside its scope. For B2B transactions, finance and tax teams need to distinguish between correcting an invoice error and adjusting the taxable amount. They also need to apply the correct invoice format as Germany’s mandatory e-invoicing requirements phase in through 2028.
An e-invoice correction in Germany is required when an invoice omits required information or states it incorrectly. Under the BMF guidance only the missing or incorrect information needs to be supplemented or corrected, not the whole invoice.
Common examples include:
• Missing invoice information: A required invoice field was omitted from the original document.
• Incorrect invoice information: A customer name, address, invoice date or other required detail was stated incorrectly.
• Incorrect VAT information: The VAT rate or VAT amount was incorrectly stated.
• Incorrect description of goods or services: The structured invoice data does not correctly describe the goods or services supplied.
• Invoice information affected by a change in the underlying transaction: A change to the scope or substance of the transaction generally requires the affected invoice information to be corrected rather than being treated only as a change in the taxable amount.
This last distinction is particularly important where the description of the supply is affected. The BMF treats a change in the scope or content of a service, such as a relevant change in measurements for construction work, as more than a change in the taxable amount. It generally requires a correction of the invoice, at least regarding the description of the service.
A later change in the taxable amount does not mean the original invoice was incorrect. Under §17 UStG, such a change can require the supplier to adjust the VAT due and the recipient to adjust the related input VAT, depending on the circumstances.
Typical examples are a later discount, rebate or price reduction that changes the taxable amount without changing the underlying supply. The current German VAT Application Decree identifies discounts and price reductions as cases where a separate invoice correction is not required.
Correcting an e-invoice requires identifying what went wrong and determining the appropriate treatment. The process has four steps: identify the error, link the correction to the original invoice, state the corrected information, and issue the correction in the format required for the transaction.
Start by identifying the exact information that is missing or incorrect. Check the invoice against the underlying transaction, the applicable VAT treatment and the required invoice information. Then establish why the amount or content changed:
A correction must specifically and unambiguously refer to the original invoice. This is normally met when the correction document includes the sequential number of the original invoice, which lets the recipient and the accounting records establish which invoice is being corrected.
A new invoice number is not required merely because a correction is being issued. What matters is that the correction document clearly identifies the original invoice.
The correction should identify the missing or incorrect information and provide the correct information. It can address individual invoice items without recreating every element of the original invoice. If only the VAT amount is wrong, for example, the correction should make the VAT correction clear while retaining the link to the original.
A separate transmission containing only the corrected data is not enough where a formal correction is required. The correction must be a document that meets the applicable requirements and refers to the original invoice. It is generally made by the invoice issuer.
Where an e-invoice is required for the underlying transaction, the correction must also be issued in the prescribed e-invoice form using the appropriate invoice type. Transmitting the missing or incorrect information in another form is not sufficient in that case.
Under §14 UStG, an e-invoice is a structured electronic invoice issued, transmitted and received in a format that enables electronic processing. Compliant formats include XRechnung and ZUGFeRD profiles that conform to EN 16931, where the applicable legal and technical requirements are met.
The table below sets the four situations side by side. One term needs particular care: Gutschrift. Before using a commercial credit document or calling a later price adjustment a “Gutschrift,” note that under German VAT rules a Gutschrift is an invoice issued by the recipient of the supply under a self-billing arrangement. It is not another name for a correction of an earlier invoice.
| Situation | What happened? | What to do |
| Incorrect invoice information | Required information on the invoice is missing or wrong. | Correct the missing or incorrect information. |
| Incorrect VAT information | The VAT rate, VAT amount or other VAT details are wrong. | Correct the relevant VAT information. |
| Discount or bonus after invoicing | A discount or bonus is granted after the original invoice, reducing the taxable amount. | Apply §17 UStG where the taxable amount is reduced. |
| Change in the supply | The scope or substance of the goods or services supplied changed. | Check and correct the affected invoice information, including the description where necessary. |
The following example illustrates how a business can correct an incorrect VAT amount while clearly linking the correction to the original invoice and maintaining a traceable invoice record.
Because the VAT amount on the original invoice is incorrect, the correction should identify INV-2026-0158 and replace €180 with the correct VAT amount of €190
The correction document specifically identifies INV-2026-0158 and states the corrected VAT amount. The original and corrected records can therefore be connected throughout the accounting process. The BMF guidance confirms that a correction document does not require a new invoice number solely because it is a correction.
Note: Illustrative example, not an official BMF template.
The required format is determined by the e-invoicing requirements applicable to the original transaction, including any transition provisions in force at that time. Within Germany’s e-invoicing requirements, the transition framework allows businesses to continue issuing other invoice formats during 2026 and, under specific conditions, through 2027.
From 1 January 2025 through 31 December 2026, invoice issuers can generally use a paper invoice or another permitted invoice format instead of an e-invoice. An electronic format such as a PDF can be used where the applicable consent requirement is met.
This means a correction does not automatically have to use an e-invoice where the transaction is still covered by the transition framework. The UStAE says so expressly: where no e-invoice obligation applies under the transition provision, the correction can also be made without an e-invoice.
The transition period changes the format requirement. It does not remove the requirement to correct incorrect invoice information.
For businesses with previous-year turnover of up to €800,000, the transition allowing other invoice formats continues through 31 December 2027. A separate transition provision also allows certain EDI-based invoicing procedures to continue until 31 December 2027.
The €800,000 threshold applies only to issuance, not receipt. Finance and ERP workflows should therefore determine the applicable issuance requirement for each transaction rather than using the threshold to determine whether the business must receive e-invoices.
After the transition periods expire, e-invoice issuance becomes mandatory for applicable domestic B2B transactions, subject to statutory exceptions. For these transactions, a correction must follow the structured e-invoice requirements.
The current BMF FAQ confirms the 2026 transition, the extended 2027 transition for issuers meeting the €800,000 previous-year turnover condition and the subsequent mandatory use of e-invoices.
A correction should not be treated as an isolated document-generation task. Finance and tax teams should maintain a traceable relationship between the original invoice, the correction and the related accounting entries.
The correction record should remain linked to the original invoice throughout the accounting workflow. At a minimum, the audit trail should make it possible to identify:
• The original invoice.
• The information that was incorrect or missing.
• The corrected information.
• The reason for the correction.
• The date and document used to make the correction.
The original invoice should not disappear from the accounting history when a correction is issued. The purpose is to establish what was originally issued and what was later corrected.
Businesses must retain invoices for the statutory retention period. Under §14b UStG, invoices must generally be retained for 8 years, with the retention period beginning at the end of the calendar year in which the invoice was issued.
For structured e-invoices, retain the invoice data in a form that continues to meet the applicable requirements throughout the retention period. This is particularly relevant where data moves between an ERP system, an e-invoicing application and accounting records.
The correction should be reflected in the relevant accounting records, with the original amount distinguishable from the corrected amount. Where the correction affects VAT, update the VAT records consistently with the corrected invoice.
Applying the right treatment prevents the same adjustment from being recorded twice: once as an invoice correction and again as a separate taxable-amount adjustment.
Correcting an e-invoice in Germany starts with identifying what changed. Missing or incorrect invoice information requires a correction linked to the original invoice, while later changes to the taxable amount may instead fall under §17 UStG.
Finance teams should check the reason for the change, use the required invoice format, link the correction to the original invoice and maintain a clear audit trail. Doing this consistently helps keep invoicing accurate and traceable while keeping the business prepared as Germany’s e-invoicing requirements move toward full mandatory use in 2028.
No, not when the correction must be issued as an e-invoice. During the transition period, other formats may be permitted where the applicable conditions are met.
Yes. The correction must specifically and unambiguously refer to the original invoice, such as by using its invoice number.
Not automatically. A later discount or rebate may instead be treated as a change in the taxable amount under §17 UStG.
Yes. Individual invoice positions can be corrected in a subsequent e-invoice if the correction clearly refers to the original invoice.
No, not automatically. The key requirement is that the correction can be specifically and unambiguously linked to the original invoice.
