Germany's issuing obligation starts in January

Since 1 January 2025 a business established in Germany has had to be able to receive an electronic invoice for domestic business-to-business supplies. The obligation to issue one arrives later and in two steps: from 1 January 2027 where the issuer's turnover in the preceding year exceeded EUR 800,000, and from 1 January 2028 for everyone else, with a separate transitional allowance for EDI arrangements running to the end of 2027. The finance ministry's administrative guidance sets out how the rules are applied. The unsettled part, for many groups, is the threshold question itself, because it is asked of each taxable person separately. This perspective is general information, not legal advice.

The obligation

Receiving was 2025. Issuing is 2027.

The German reform separated the two halves of an invoice. The receiving half has been live since 1 January 2025: a business established in Germany must be able to take delivery of an electronic invoice in a structured format that meets the European standard EN 16931. The finance ministry has been unusually pragmatic about what that requires, confirming that providing an email address is enough to satisfy the receiving obligation.

The issuing half was deferred, and the deferral is what most groups are living inside now. Through the end of 2026, any issuer may still send a paper invoice, or another electronic format such as a PDF where the recipient agrees to it. The distinction matters, because a PDF is an other format, permitted for now by consent, and consent stops being available once the issuing obligation applies to that entity.

The calendar

Last year's turnover decides the date

The general transitional rule runs to 31 December 2026. A second transitional rule extends that latitude to 31 December 2027 where the issuer's turnover in the preceding year did not exceed EUR 800,000. Read forward, that produces two start dates: 1 January 2027 for issuers above the threshold, and 1 January 2028 for those at or below it. A separate rule allows an EDI procedure that does not itself meet the e-invoice requirements to continue until the end of 2027.

Several categories sit outside the obligation altogether, including small-amount invoices up to EUR 250, travel tickets, supplies exempt under the relevant provisions of the VAT Act, supplies made by businesses under the small-business regime, and supplies to recipients who are not taxable persons. Useful as those are, they are entity-level and transaction-level facts that somebody has to establish and record, one German company at a time.

One group, several taxable persons

A German structure has no single German answer

A group with German holding companies, property vehicles and a management company gets a different answer for each of them. The threshold looks at the turnover of the issuer in the preceding year, so it is tested per taxable person. A management company charging fees across the structure may sit well above EUR 800,000 while the GmbH holding a single building sits far below it, and the two therefore start issuing structured invoices a year apart.

Two complications follow. Where a VAT group exists, the identity of the taxable person is not obvious from the company register, and that has to be settled before anyone assumes the threshold is measured on a subsidiary's own turnover. And the turnover figures that decide the answer for 2027 are 2026 figures, being earned now and confirmed by an accountant months after the date they determine. Nobody outside the group can see the figure, so nobody outside the group will tell you which side of the line an entity landed on.

The threshold test

An entity attribute, reviewed every year

The finance system cannot answer this on its own. It holds transactions, and the question is about a governed list of legal entities and their attributes. What is needed against each German entity is a small set of recorded facts: whether it is established in Germany for these purposes, whether it belongs to a VAT group and which entity is the taxable person, its prior-year turnover against the EUR 800,000 threshold, whether it issues invoices at all and through whom, and the date its issuing obligation therefore begins.

Those facts move, so the work is a review and never a project. Once the 2026 figures are final, every German entity's start date is confirmed or shifted, and the ones that cross the threshold for the first time acquire a deadline they did not have the year before. A new acquisition arrives with an unanswered version of the same list. Recording who established each answer, and when, is what keeps the next round a review and stops it becoming a fresh investigation. It also settles the awkward question that arises when an obligation is missed, which is rarely what the rule said and almost always who was supposed to be watching it.

In Alethia

The entity register carries the attribute and the date

An e-invoicing start date is a compliance obligation attached to a specific German entity. The turnover position and the VAT group status are attributes of that entity, the access point or service agreement is a document filed against it, and the audit trail records who established each answer and when. So the group can put the question the way it actually arises: show every German entity, its issuing start date, and the evidence behind the threshold answer. Alethia computes no turnover, issues no invoices and files nothing with a tax administration. What it takes out of the year is the meeting where finance and tax each arrive with a different list.

Questions

The German e-invoicing timetable, answered

Does every German business have to start issuing e-invoices on 1 January 2027?

No. That date applies where the issuer's turnover in the preceding year exceeded EUR 800,000. Below the threshold the transitional rule runs a further year, so the obligation begins on 1 January 2028. The threshold is tested on the issuer, which means the same group can have entities on both dates.

Our German entities issue almost nothing. Is there anything to do before 2027?

The receiving obligation has applied since 1 January 2025 regardless of turnover, and it is the half that is easy to fail without noticing. A dormant or lightly trading entity still needs a route by which a supplier's structured invoice reaches somebody who reads it.

Is a PDF invoice acceptable?

Under the transitional rules a PDF is an other electronic format that may be used where the recipient agrees. It is not an electronic invoice for the purpose of the obligation, so it stops being an option for that entity once its issuing date arrives.

Two start dates, and only you can tell which entity gets which

Record, for each German entity, its VAT group position, its prior-year turnover against EUR 800,000 and the resulting start date, then revisit the list when the accounts are finalised.
