E-invoice in Germany 2026: obligation, PDF and deadlines 2025–2028
In 2026, regular PDF may still work temporarily, but it's not a German e-invoice. Find out when your company must receive structured invoices, when to issue them, and whether a DE VAT number alone makes any difference.
Four principles that organize the topic
An e-invoice contains data that the system can automatically read and process.
The company may be obligated to collect earlier than to issue.
A German VAT number alone does not imply a registered office or permanent establishment in Germany.
Exhibitors can still use paper and – with the recipient’s consent – PDF.
PDF ≠ e-invoice
The method of sending the document or its appearance is not decisive. What matters is its structured format, consistent with technical requirements.
Standard electronic invoice
- PDF, scan or photo,
- data read mainly visually,
- in 2026, temporarily possible with the recipient's consent.
E-invoice
- data in a machine structure,
- automatic accounting and validation,
- e.g. XRechnung or the appropriate ZUGFeRD.
The required VAT data must be included in the structured section. A visualization or attachment may supplement it, but not replace it.
Official explanations: BMF - FAQ on e-invoices and § 14 UStG.
From collection in 2025 to full principle in 2028
Companies subject to the German rule must be technically ready to receive e-invoices. A simple email inbox may suffice.
Any issuer can still use paper. PDF and other unstructured formats require the recipient's consent.
This is made easier for exhibitors whose turnover in the previous year did not exceed EUR 800,000. A special transition is also underway for EDI.
In domestic B2B transactions covered by the obligation, the invoice should be issued as an e-invoice, unless an exception applies.
Basis for transitional periods: § 27 UStG.
First, check the transaction and status of both parties
The rule applies primarily to domestic B2B transactions where the issuer and recipient are established in Germany.
Usually in the range
- B2B delivery or service taxable in Germany,
- both parties have their registered office, management board or participating Betriebsstätte in Germany,
- the statutory exception does not apply.
The most important exceptions
- small invoices up to EUR 250,
- travel tickets,
- selected exempt benefits indicated in § 4 UStG.
B2G may require XRechnung, a collection channel, and an ordering ID. This guide focuses on e-invoicing in B2B relationships.
VAT number DE ≠ establishment in Germany
Registration for German VAT does not, in itself, establish a registered office or permanent establishment. The actual structure of the company must be investigated.
Storage of goods may trigger VAT obligations, but for e-invoicing obligations, the existence of a participating fixed establishment is still examined. See also VAT registration in Germany.
XRechnung, ZUGFeRD or EDI?
| Format | What's included | Status | The most important note |
|---|---|---|---|
| Document image | Other electronic invoice | It is not an e-invoice; in 2026 it requires the recipient's consent. | |
| XRechnung | Structured XML | E-invoice | Machine format without the necessary visual layer. |
| ZUGFeRD ≥ 2.0.1 | PDF/A‑3 + embedded XML | E-invoice in the appropriate profile | MINIMUM and BASIC‑WL profiles do not meet the requirement. |
| EDI | Agreed data exchange | Possible after meeting the requirements | Content must match the required data; a specific transition works. |

The process from inbox to accounting
E-mail may be sufficient. The parties may also agree on a portal, EDI, or other secure transmission method.
Maintain the original structure and link the document to the contractor and transaction.
First the format and schema, then tax, business and accounting data.
Ensure readability, integrity, access and audit trail throughout the retention period.
1. Technical validation
Does the file have the correct format, schema, version and complete set of required fields?
2. Content validation
Are the parties, VAT ID, dates, amounts, rates and transaction description correct?
During the transitional period, the recipient's consent is required for plain PDF or other unstructured electronic formats.
Archiving, proofreading and gutschrift
The period is counted from the end of the calendar year in which the invoice was issued. The original file must remain available.
If the original transaction is subject to e-invoicing, the correction of the invoice data should also maintain the correct structure.
The name of the process does not exclude the obligation. What matters is the parties, the transaction, and the statutory scope.
Basis for storage: § 14b UStG. The detailed elements of a standard invoice are the subject of a separate guide.
Common Mistakes - and Quick Fixes
The file looks like an invoice, but has no structured data.
What to do: Use compliant XML or a hybrid.The company is waiting for its own obligation to issue.
What to do: Prepare your channel and accountability now.The tax number is treated as a permanent place of residence.
What to do: Investigate the facility's resources and participation.Correct XML contains incorrect VAT ID or amounts.
What to do: add content control.The company deletes the structure after generating the preview.
What to do: Keep the original data file.The key information is only in the visualization.
What to do: Place them in a structure.E-invoice implementation checklist

Check the scope of the obligation before changing the invoicing process
We will analyze the company's status in Germany, transaction types, transition periods, and required document flow – without implementing a tool that the company does not need.
Frequently asked questions about e-invoicing in Germany
Is PDF an e-invoice in Germany?
No. A standard PDF is a different electronic invoice because it does not contain the required structure for automated processing. It may be used temporarily in 2026 with the recipient's consent.
Will e-invoices be required in 2026?
Not in every situation. All issuers can benefit from the transitional rules until the end of 2026. However, the collection obligation, which applies from 2025 for companies covered by the German rule, must be examined separately.
Does the DE VAT number itself trigger the obligation to issue e-invoices?
No. A German VAT number does not automatically establish a registered office or permanent establishment. What matters is the actual structure and involvement of the German branch in the transaction.
Can a company outside Germany voluntarily send e-invoices?
Yes, if the recipient can handle it and the format meets the requirements. Voluntary use can simplify collaboration, even if a given transaction is not legally required.
How can I receive e-invoices?
There is no single mandatory portal. In the basic scenario, an email inbox is sufficient. Parties can agree on a portal, EDI, API, or other secure channel.
Is ZUGFeRD always consistent?
Not every profile. The BMF generally recognizes ZUGFeRD from version 2.0.1, with the exception of the MINIMUM and BASIC‑WL profiles. Data required for tax purposes must be included in the structured part.
How long should e-invoices be stored in Germany?
As a rule, this is eight years from the end of the calendar year in which the invoice was issued. The original structured part must be retained and its accessibility and integrity must be ensured.
E-invoice is a change of process, not just file format
In 2026, regular PDF remains a transitional solution, not an e-invoice.
A DE VAT number alone does not mean that a company is established in Germany.
The most secure process combines receipt, two-step validation and structure archiving.
More on general obligations: VAT in Germany. It is worth assessing the scope of the e-invoicing obligation separately from VAT registration and declaration.
