Deductions and Tax Benefits

Tax Return in Spain 2026

Filing your tax return in Spain is a legal obligation for all taxpayers, whether residents or non-residents. This process is governed by the Personal Income Tax (IRPF), which applies to income earned during the fiscal year. Understanding your responsibilities, deadlines, and available deductions is essential to ensure compliance and avoid penalties. Below is a comprehensive guide to the Spanish tax return process for 2026.

Who Must File a Tax Return in Spain?

The obligation to file depends primarily on income levels and the number of payers:

  • Single payer: taxpayers earning more than €22,000 annually from one source must file.
  • Multiple payers: the threshold drops to €14,000 annually if income comes from multiple sources.
  • Other income: capital gains, investment income, and rental income may also require filing.

Exemptions

Individuals whose annual income from non-employment sources does not exceed €1,000 are exempt. Likewise, those receiving only exempt income, such as certain pension plans, are not required to file.

Residents vs Non-Residents: Key Differences

Residency status significantly impacts tax obligations:

  • Residents: anyone spending more than 183 days per year in Spain or having their main economic interests in Spain is considered a resident. Residents must declare worldwide income.
  • Non-residents: only income earned within Spain is taxable.
    • EU residents: Taxed at 19%.
    • Non-EU residents: Taxed at 24%.

Important Deadlines for 2026

The Spanish tax year runs from January 1 to December 31. For 2026:

  • Campaign start: April 1, 2026
  • Deadline for filing: June 30, 2026
  • Deadline for direct debit payments: June 25, 2026

Missing these dates can result in penalties, so mark your calendar.
