Understanding the “extra reducción autonómica” in your IRPF can significantly lower your tax bill—especially if you live in Andalusia.
Each Spanish autonomous community offers its own tax reductions on top of the national ones, and many taxpayers miss out simply because they don’t know they exist.

This guide explains what the regional reductions are, how they work, and what you can claim—starting with Andalusia, the region with some of the most extensive tax benefits.

What Is the Extra Regional Reduction (Reducción Autonómica) in Modelo 100?

Spain’s income tax (IRPF) has two components:

• State portion
• Regional (autonómica) portion

Each autonomous community can introduce its own deductions and reductions, which apply only if you are a tax resident in that region. These reductions directly lower the regional part of your tax bill.

Andalusia: The Region With the Most Extensive Extra Reductions

Andalusia offers a wide range of regional deductions covering family, housing, education, disability, rural residency, environmental contributions, and more.

Below are the most relevant categories.

Family‑Related Reductions

• €200 per child born, adopted, or in foster care
• €600 for international adoptions
• Double deduction if you live in a municipality with depopulation risk (under 3,000 inhabitants)
• €200 for large families (€400 for special category)
• €100 for single‑parent families (+€100 per dependent over 75)

Disability‑Related Reductions

• Deductions for taxpayers with disabilities
• Deductions for dependents or spouses with disabilities
• Deductions for expenses related to disability assistance

Housing‑Related Reductions

• 6% deduction for investment in protected habitual housing for young people
  • Income limits apply (€25,000 individual / €30,000 joint)
• 15% deduction for rent on habitual residence
  • Up to €1,200 (€1,500 if disabled)
  • Available to taxpayers under 35, over 65, or victims of domestic violence/terrorism

Education & Training

• Deductions for language learning and digital skills
• Deductions for school‑related expenses

Health & Lifestyle Deductions (New and Highly Relevant)

15% Gym Membership Deduction (up to €100)

Andalusia allows a 15% deduction on gym or sports center membership fees, capped at €100 per year. This applies to expenses aimed at improving physical health and preventing sedentary lifestyles.

€100 Deduction for Coeliac Disease

Taxpayers diagnosed with coeliac disease can claim a €100 annual deduction to compensate for the higher cost of gluten‑free products.

These two deductions are among the most practical and easiest to apply, yet many taxpayers overlook them.
