What does UBL-SR-49 mean? Value tax point date shall occur maximum once
Why did my invoice fail UBL-SR-49?
The Value added tax point date (BT-7) is the date on which VAT becomes chargeable, carried as cac:InvoicePeriod/cbc:... (TaxPointDate at document level). EN 16931 allows the VAT point date to occur at most once. A single tax point date keeps the VAT chargeability moment unambiguous for the whole invoice.
Official rule text
Value tax point date shall occur maximum once
Common causes
- cbc:TaxPointDate is emitted more than once at document level.
- A period/date block was duplicated during template generation.
- Both a tax point date and a redundant copy were written from different source fields.
How do I fix it?
Keep a single value, e.g. one <cbc:TaxPointDate>2026-07-31</cbc:TaxPointDate> at the document level, and remove any duplicate.
