GIPUZKOA: The campaign for Societies begins shortly

What is the deadline to submit my self-assessment?

Within 25 calendar days following the 6 months after the end of the tax period. For self-assessment purposes, the period considered is from 1-1-2025 to 31-12-2025; if your company's period ended on December 31, you will be able to submit the self-assessment from July 1 to July 27 (July 25 and 26 are Saturday and Sunday, respectively). After this period, if the result is payable and you have opted for direct debit, the payment will be made on July 28.

How do I need to submit it?

√   Online

This is the method of submission that should be used in general, and it is done through the help program available on the "Zergabidea" platform:

• It can be accessed through the portal https://zergabidea.gipuzkoa.eus , or through the Tax Office website https://www.gipuzkoa.eus/es/web/ogasuna .
• If your company applies state, Alava, or Biscayan regulations, and also pays taxes in Gipuzkoa, you must create a file using the programs approved by the respective Administrations, and then transmit it:

 

Applicable regulations for the company	File transmission
Alava or Biscayan	You need to "import data" in "Zergabidea" and use the "society converters" option.
State	The file is transmitted through "Zergabidea" without the need to use a converter.

 

√ On paper

  You will have to submit the self-assessment on paper if your company is taxed in Gipuzkoa based on the volume of operations, but is subject to Navarre regulations.

Our professionals will inform you about all the details of this campaign.
