Spain's tax filing season begins: key deductions to watch
Spain's tax authorities are set to launch the 2026 tax filing season, giving taxpayers just over three months to take advantage of various deductions to lower their tax bills for 2025. As the deadline approaches, several key areas will be under closer scrutiny, including the wealthy and self-employed.
Wealthy individuals face higher tax rates
Starting this year, individuals with patrimonies exceeding €300,000 will face a 1% increase in their tax rate, up from 14% to 15%. This affects assets such as cryptocurrencies, real estate, and other high-value holdings.

Self-employed face greater scrutiny
Autonomous workers, who often have more gray areas when it comes to justifying business expenses, will also be under the microscope. This includes the first year that the Spanish tax authority, AEAT, will consider regularizing social security contributions as a factor in determining deductions.

Local and state deductions crucial
Taxpayers should also be aware of various local and state deductions available, which can significantly reduce their tax liability. However, it's essential to ensure that all claimed deductions are properly justified, as any discrepancies could lead to audits or penalties.
With the tax filing season now underway, taxpayers would do well to review their eligible deductions, as well as any changes to tax laws or regulations that may impact their filings. The Spanish tax authorities are cracking down on non-compliance, so accuracy and transparency are key to avoiding any unwanted attention from the taxman.
