Modelo 349 of Bizkaia: Resumen recapitulativo de operaciones con sujetos pasivos de la UE

Who files it

Exceptions and special cases

All its deadlines

Each row is a deadline from the official calendar: the last day to file. When that day falls on a Saturday, Sunday or public holiday, the calendar already moves it to the next working day.

* Date worked out with the deadline rule, because the official calendar for that year has not been published yet. Check it when it comes out.

Every deadline of the year, month by month: the 2026 tax calendar for Bizkaia.

The same obligation with other tax authorities

What is declared here with form 349 goes on a different form, with different deadlines, at other tax authorities. Which one applies to you depends on where you are taxed, not on where you live.

Official links

Where it is filed, its instructions and, if there is one, the file format for importing it. All on the website of the Hacienda Foral de Bizkaia (Bizkaia’s own tax authority).
