VAT_RATE_NOT_ACCEPTED_ON_DATE

When it happens

A line carries a temporary VAT rate on an operation outside its period: 5 % is accepted only on operations dated from 2022-07-01 to 2024-09-30, and 2 % and 7.5 % from 2024-10-01 to 2024-12-31. The date judged is the invoice's operation_date, or its issue date when it has none.

How to fix it

Send the operation_date of the rate's period, or the rate in force. GET /v1/tax-types publishes each rate with its valid_from / valid_until.

Retry

Not as is: the same request fails the same way. Fix the cause described above, then send the request again, under a new Idempotency-Key if the body changed.
