EC Sales List (Zusammenfassende Meldung) from invoice data

What belongs in the EC Sales List

The EC Sales List (Zusammenfassende Meldung, ZM) is a separate EU B2B report under § 18a UStG. It is not the same as the OSS procedure for certain cross-border B2C sales.

The ZM mainly covers:

• L: intra-community supplies of goods under § 6a UStG,
• D: supplies in an intra-community triangular transaction under § 25b UStG,
• S: certain services under § 3a Abs. 2 UStG where the business recipient owes the tax in the other EU member state.

Rechnungskit does not take this classification from a freely editable report form. It is already made in the VAT matrix on the invoice line. That keeps invoice, VAT ID, date of supply, type of sale and the later report run linked to each other.

How a report run works

1. Classify the sale. The VAT matrix detects intra-community supplies, triangular transactions and certain EU B2B services where the recipient owes the tax. Only lines relevant for the ZM are taken over.
2. Determine the reporting period. Rechnungskit checks the 50,000 euro limit for goods and triangular transactions in the current and the four previous quarters and shows the required monthly or quarterly period.
3. Lock the report. Amounts are totaled per VAT ID and type of sale, carried over in whole euros and archived immutably as an ELSTER-compatible CSV together with the source and the frequency decision.
4. Document the filing. You import the file into Mein ELSTER and then mark the report as filed. The ELSTER or BZSt confirmation is archived with a checksum; errors found later start their own correction workflow.

Automatic frequency check instead of a calendar note

For supplies of goods and triangular transactions the calendar month is the general rule (§ 18a Abs. 1 UStG). If the sum of taxable amounts stays at no more than 50,000 euros in the current and in each of the four previous calendar quarters, you can report quarterly. If the limit is exceeded in the current quarter, Rechnungskit applies the statutory transition logic and shows the required monthly periods.

Services are generally reported quarterly. If you already have to report L or D sales monthly, the quarterly S lines appear in the last month of the quarter (§ 18a Abs. 2 UStG). A voluntary monthly S report is recorded as a documented decision of your tax advisor.

The regular filing deadline is the 25th day after the end of the reporting period. Each deadline is shown right in the ZM workspace.

ELSTER import file with a traceable source

Before locking, Rechnungskit shows two levels:

1. the report lines totaled by VAT ID and type of sale, and
2. the source details per invoice and correction document.

Only then is the CSV created for the EC Sales List import in Mein ELSTER. Rechnungskit uses the official record format, maps the L, S and D codes and splits files automatically when there are more than 1,500 report lines. You can also download a review CSV at the level of individual documents.

Note: Rechnungskit does not submit the report itself. You or your tax advisor import the file into Mein ELSTER, review it there and send it with authentication.

Locking, confirmation and correction

When locking, Rechnungskit archives the report data, the frequency decision and the generated import files with SHA-256 checksums. After submission you mark the run as filed and upload the ELSTER or BZSt confirmation. That keeps visible what was generated, what was submitted and what was actually confirmed.

If an error is found later, a separate correction workflow starts. § 18a Abs. 10 UStG requires the correction within one month of becoming aware of the error. Rechnungskit documents when the error was discovered, shows the deadline and creates a correction file that fully replaces changed totals and reports dropped lines with zero.

For intra-community supplies this matters most, because under § 4 Nr. 1 Buchst. b UStG a missing or wrong ZM can put the VAT exemption of the affected supply at risk.
