Major Updates to the 2025 Income Tax Return

This year, the Bizkaia Tax Authority, through Order 108/2025, introduces several changes to streamline the tax return process:

🔹 Automatic confirmation of refund-eligible tax drafts: If the Provincial Council of Bizkaia generates a tax draft showing a refund, and the taxpayer neither modifies nor confirms it before June 30, the return will be considered automatically filed. However, explicit submission will still be required in the following cases:

  • If the taxpayer explicitly submitted their return in the previous campaign.

  • If the refund amount exceeds €300, except for taxpayers over 65 years old.

🔹 Unification of the Wealth Tax and the Temporary Solidarity Tax on Large Fortunes: Starting this year, both tax declarations must be filed together when applicable.

🔹 Discontinuation of the Wealth Tax assistance program: This tax return must now be submitted exclusively through a web application, which will allow for the automatic integration of taxpayers’ fiscal data.
