How to pay less in Renta 2025? State and regional tax deductions in Spain

Spain's Renta 2025 tax return (the income tax campaign that opens in April 2026) is not just an administrative formality — it is also your annual opportunity to reduce your tax bill by applying every deduction the law allows. Those deductions fall into two broad categories: state-level deductions, which apply uniformly across mainland Spain, and regional deductions (deducciones autonómicas), which each autonomous community regulates independently and which can generate significant additional savings depending on where you live.

This guide covers both categories in full for tax year 2025. For each deduction you will find a plain-language explanation of who it is for, what it covers and a direct link to the official AEAT Practical Guide so you can check the technical details. If you want to understand the underlying tax framework first, the articles on what IRPF is and how it works and income tax concepts in Spain are a good starting point.

How tax deductions work in Spain

Before diving into the list, a quick reminder of the mechanics. Spanish income tax is calculated by applying progressive rates to your taxable base, which produces the cuota íntegra (gross tax liability). Deductions are then subtracted directly from that liability — not from the taxable base — which makes them particularly powerful: every euro of deduction means one euro less in tax paid.

State deductions are governed by the national IRPF Law and apply equally to all contributors in the common territory (the Basque Country and Navarre have separate foral regimes). Regional deductions are approved by each autonomous community and apply only to the portion of the tax that corresponds to the regional rate. This means deductions at both levels can sometimes stack: the same circumstance — renting your home, for example — can give rise to both a transitional state deduction and a regional deduction at the same time.

State deductions in Renta 2025

The AEAT consolidates all state-level deductions in Chapter 16 of the Practical Guide to IRPF 2025. Here is a summary of each one.

Primary residence investment deduction: transitional regime

The general deduction for investment in a primary residence (vivienda habitual) was abolished in 2013, but it survives under a transitional regime for contributors who had acquired or commenced payments on their main home before 1 January 2013. If you meet that threshold, you can continue applying the deduction even though you have kept paying the mortgage after that date.

The official guide covers the transitional regime in detail, including the general conditions and the different modalities (acquisition, construction, extension, and renovation). If you have a mortgage that predates 2013, this remains one of the most valuable deductions to review every year.

Investment in newly or recently incorporated companies

This deduction is designed to encourage capital flows into startups and young companies. Business angels and early-stage investors who subscribe shares or holdings in a newly or recently created entity may benefit from it, provided both the investor and the company satisfy specific requirements.

The official guide sets out the deduction's scope, the maximum base, the applicable percentage, the requirements on the company, the conditions the contributor must meet, and the joint ceiling that applies alongside other deductions. It is particularly relevant for anyone active in Spain's start-up ecosystem.

Business investment incentives — direct assessment regime

This block applies to contributors who run economic activities under the direct assessment regime (estimación directa, normal or simplified). Through this route, the IRPF borrows the investment incentives from the Corporate Income Tax framework with appropriate adaptations.

The official guide distinguishes between the general regime and special regimes, investment in new tangible fixed assets or real estate investments tied to the business, the special regime for business investments in the Canary Islands, and the special fiscal regime of the Illes Balears. Self-employed contributors in direct assessment who have made significant capital investments should review this chapter carefully.

Business investment incentives — objective assessment regime

This block applies to contributors with economic activities taxed under the objective assessment regime (estimación objetiva, commonly known as módulos). The law states that investment incentives under this regime only apply when expressly established by regulation. For tax year 2025, the AEAT confirms that no such regulatory provision has been made, meaning this block generates no practical deductions for contributors in módulos this year.

Deductions for donations and other contributions

If you make charitable donations, this is one of the most important deduction blocks to review. It covers donations to entities governed by Law 49/2002 (foundations, declared public-utility associations, international development NGOs and similar bodies), donations to entities outside that special regime, and contributions to political parties, federations, coalitions and electoral groupings.

The deduction percentage varies by the nature of the recipient, and Law 49/2002 entities benefit from an additional incentive when the donor gives recurrently over multiple years. The official guide covers the common requirements and the maximum limit expressed as a proportion of the taxable base.

Deduction for income obtained in Ceuta or Melilla

Contributors who obtain certain types of income in the autonomous cities of Ceuta or Melilla are entitled to a specific state deduction, designed to compensate for their geographic remoteness and economic conditions. The official guide explains the different modalities depending on what type of income is involved, defines which income qualifies as obtained in those cities, and sets out the applicable maximum limit.

Deduction for habitual residence on the island of La Palma in 2025

This deduction applies to contributors whose habitual and effective residence is on the island of La Palma in the Canary Islands. The measure, introduced in the aftermath of the 2021 volcanic eruption and its lasting economic and social consequences, has been extended to cover tax year 2025. It follows the same logic as the Ceuta and Melilla deduction, adapted to the specific context of La Palma as an island territory that has suffered extraordinary damage.

Deduction for actions to protect and promote Spanish and World Heritage

This deduction covers certain investments or expenditure connected with Spanish Historical Heritage and UNESCO World Heritage. The qualifying scenarios listed in the official guide include the acquisition of certain goods forming part of the Spanish Historical Heritage, activities of conservation, repair, restoration, dissemination and exhibition of protected assets, and the rehabilitation, maintenance and improvement of protected buildings and their surroundings.

It has a narrower scope than housing or donation deductions, but is highly relevant for people involved in the management, conservation or acquisition of heritage-listed assets.

Rental of main residence deduction: transitional regime

The general state deduction for renting a main residence was abolished in 2015, but it remains in force under a transitional regime for contributors who were already entitled to it before that year and met the conditions then in effect. The official guide details who can still apply it in 2025, how it is calculated, the amount of the deduction, the deduction base and the maximum base.

This transitional state block coexists with regional rental deductions, which are entirely separate. If you have been renting under a contract predating 2015 and met the income and age requirements at the time, it is worth verifying whether you can still benefit.

Deductions for energy efficiency improvement works in homes

This state block covers three types of energy renovation works. The first applies to works that reduce the demand for heating and cooling in the home. The second covers works that reduce consumption of non-renewable primary energy. The third, with the broadest scope, addresses energy rehabilitation works in predominantly residential buildings.

Each line has its own deduction percentage, maximum base and documentary requirements — energy performance certificates play a central role in proving the improvement achieved. If you carried out qualifying works in 2025, you can find detailed guidance in the dedicated article on energy efficiency deductions in Renta 2025.

Deductions for the acquisition of electric vehicles and charging points

Two temporary state deductions coexist in this block: one for the purchase of certain new electric vehicles and one for the installation of charging infrastructure. Both apply a 15 % rate to the eligible base, with different ceilings — up to €20,000 for the vehicle and up to €4,000 for the charging point.

The official guide sets out the applicable percentage, maximum base, validity period and technical requirements for each. If you bought an electric car or installed a home charger in 2025, the article on the electric vehicle and charging point deduction in Renta 2025 covers every detail (currently available in Spanish).

Deduction for family units with members resident in the EU or EEA

This deduction is designed for family units in which one or more members have their tax residence in another EU Member State or in a country of the European Economic Area. The rationale is to ensure such families are not placed at a fiscal disadvantage because their members live in different countries.

The official guide defines the eligible cases, sets out the necessary conditions and explains how the deduction is calculated. It is a narrow deduction rather than a mass-market measure, but it is relevant for anyone in a cross-border family situation within the European space.

Regional deductions in Renta 2025 by autonomous community

On top of the state deductions, each contributor can apply those approved by their autonomous community of residence. The AEAT publishes a consolidated guide covering all of them at the Autonomous Community Deductions Guide for IRPF 2025. Below you will find a summary for each community with a link to its official section.

Frequently asked questions about tax deductions in Renta 2025

What is the difference between state and regional tax deductions in Spain?

State deductions are set by the national IRPF Law and apply equally across mainland Spain regardless of where you live — the pre-2013 mortgage deduction, the electric vehicle deduction and the energy renovation deductions are all examples. Regional deductions (deducciones autonómicas), by contrast, are approved by each autonomous community and only benefit contributors who are tax-resident in that territory. Both types are subtracted directly from the cuota íntegra (gross tax liability), not from the taxable base, and they are fully compatible with each other as long as each set of requirements is met independently.

How do I know which tax deductions I am entitled to in Spain?

Start from your personal and family situation: do you have children, are you a homeowner or renter, have you made charitable donations, purchased an electric vehicle, carried out energy renovation works, or care for a disabled or dependent family member? With that profile clear, review the state deductions in Chapter 16 of the AEAT's Practical Guide to IRPF 2025, then consult the regional deductions guide for your autonomous community. The draft tax return (borrador) may automatically include some figures, but regional deductions in particular are not always pre-populated, so a manual check is always advisable.

Where are regional deductions entered in the Spanish tax return?

Regional deductions have their own dedicated sections in the tax return, separate from the state-level ones. In Renta Web, look for the Deducciones autonómicas (regional deductions) section, where the application shows the deductions available for your community of residence. If a deduction does not appear automatically — common with deductions that require additional supporting documents such as school expenses or nursery receipts — you will need to enter it manually in the appropriate field. The AEAT's regional deductions guide indicates the exact box number for each deduction in each community.

What expenses are tax-deductible in Renta 2025?

Several large categories of expenditure attract deductions in the 2025 campaign. At state level, the main deductible items include mortgage payments on pre-2013 loans, energy renovation works in the home, electric vehicle or charging-point purchases, donations to foundations and NGOs, and investment in startups. At regional level, the most commonly deductible expenses include main-residence rental, school and nursery costs, specific healthcare expenses, donations to regional heritage, sustainable vehicle purchases and certain housing improvement works. In all cases, keep invoices and supporting documents safe, as the AEAT can request them.

Which Spanish autonomous community has the most tax deductions?

There is no single answer, because the "best" community depends on the profile of each taxpayer. A family with young children may find the most value in communities with generous nursery and birth deductions. A young renter will benefit more in regions with broad main-residence rental deductions. Someone who has made energy renovations or bought an electric vehicle needs to compare the regional add-ons to the state deductions. In terms of catalogue breadth, communities such as Asturias, the Valencian Community, the Canary Islands and Madrid have particularly long lists, but what matters is not the number of deductions available — it is how many apply to your specific circumstances.

Conclusion

Tax deductions in the Spanish IRPF are a genuine and accessible lever for reducing your fiscal bill. They require no special application process beyond correctly declaring them in your return, but they do demand knowing which ones apply to you and keeping adequate documentation.

State deductions apply across Spain and range from the classical pre-2013 mortgage to the newer electric vehicle, energy renovation, and start-up investment deductions. Regional deductions add a further layer that depends directly on where you live: in some autonomous communities the catalogue is very extensive and can translate into meaningful savings on housing, education, family expenses or donations.

To avoid leaving money on the table, the approach is straightforward: first review which state deductions match your situation, then consult the AEAT guide for your autonomous community to identify the regional deductions available to you.
