Autonomous Community Rankings by Net Salary

For a gross salary of €35,000, the highest net salaries are found in Madrid, La Rioja, Murcia, Cantabria, Canary Islands. At the other end sit Andalusia, Balearic Islands, Castilla-La Mancha, Catalonia. The gap between first and last is €476 per year at this level, but it grows at higher incomes, reaching €1,754 at €80,000 and €3,798 at €120,000. These figures apply the official 2026 regional scales with the state personal minimum; a few communities raise that minimum slightly.

Foral Regimes: Basque Country and Navarra

The Basque Country and Navarra operate entirely separate tax systems under historic agreements (Concierto Económico and Convenio Económico). These foral regimes have their own IRPF brackets, deductions, and allowances. Generally, the Basque provinces offer more favorable treatment for middle-income earners through wider brackets and higher personal allowances, although top marginal rates can be similar to or even higher than the common regime. Navarra sits somewhere in between, with its own unique deductions for housing and family.

Practical Example: Madrid vs. Catalonia

Consider a single worker with no children earning €45,000 gross per year. In Madrid, the combined state and regional rate tops out at 45% for the highest bracket, compared with 50% in Catalonia. After applying all brackets and the personal minimum, the Madrid worker pays €773 less in IRPF over the year. Additionally, Madrid fully rebates its regional wealth tax, while Catalonia applies one above €500,000 in assets. For high earners or those with significant savings, the cumulative difference can be substantial over a career.

Complete Regional Comparison at €40,000 Gross Salary

The following table shows the annual IRPF bill and resulting net salary for a single worker with no dependents earning €40,000 gross in each of Spain's 15 common-regime communities (the foral regimes are excluded). Social Security deductions of €2,600 and the €2,000 work-expense allowance are already factored in, leaving a taxable base of €35,400:

At €40,000 gross, the difference between Madrid (the lowest-taxed community) and Catalonia (the highest at this level) is €697 per year. The gap widens at higher salaries: €1,754 at €80,000 gross and €3,798 at €120,000.

The Foral Regimes Explained: Basque Country and Navarre

The Basque Country (comprising the provinces of Bizkaia, Gipuzkoa, and Araba/Alava) and Navarre operate under special fiscal agreements with the Spanish state that predate the Constitution. These are not simply different regional rates layered onto the state system; they are entirely independent tax systems with their own legislation, brackets, deductions, and administration.

Basque Country (Concierto Economico)

Each of the three Basque provinces has its own tax authority (Hacienda Foral) and sets its own IRPF rates. The brackets tend to be wider than the common regime, which benefits middle-income earners. For example, Bizkaia uses a structure where the first €17,360 is taxed at 23%, the next segment up to €32,960 at 28%, the portion from €32,960 to €48,960 at 35%, and income above €48,960 at rates climbing to 49%. The personal minimum allowances are generally higher than in the common regime, and there are additional deductions for housing purchases that are no longer available in most other communities. However, the top marginal rate can actually be slightly higher than in Madrid.

Navarre (Convenio Economico)

Navarre operates its own complete tax system with its own bracket structure. The rates are generally competitive for middle incomes, with a top marginal rate of around 49% for income above €300,000. Navarre offers distinctive deductions such as generous housing purchase deductions, childcare deductions that are more favorable than the common regime, and specific incentives for investment in local businesses. The personal minimum in Navarre is also structured differently, using a fixed reduction from the tax base rather than applying the minimum at the lowest bracket rate.

Regional Deductions That Vary by Community

Beyond the different bracket rates, each autonomous community offers its own catalogue of tax deductions that can materially affect your final tax bill. Here are some of the most impactful deductions that vary by region:

• Rental housing deduction: Available in Madrid (20% of rent up to €1,000), Andalusia (15% up to €600), Catalonia (10% for young or low-income tenants), and several other communities. Not available at all in some regions.
• Childcare and school expenses: Madrid offers deductions for nursery school (20% of expenses), school uniforms, and school supplies. Catalonia allows a deduction for children in childcare. Valencia has deductions for textbook purchases and language instruction.
• Home purchase or renovation: While the state-level deduction was eliminated for purchases after 2013, several communities (Basque Country, Navarre, some others) maintain their own home-purchase deductions that can reduce IRPF by up to €1,530 per year.
• Energy efficiency improvements: Several regions offer deductions for installing solar panels, improving insulation, or purchasing electric vehicles. These can range from 10% to 50% of the investment, depending on the community.
• Donations and investments: Many communities incentivize donations to local charities, cultural institutions, or investments in regional businesses with deductions ranging from 15% to 30% of the amount donated or invested.

The Fiscal Harmonization Debate

The growing gap between regional tax rates has fueled an ongoing political debate about fiscal harmonization. Proponents of harmonization argue that the current system creates unfair competition between regions, with wealthier communities like Madrid able to offer lower rates because they already have a larger tax base and higher property values. They contend that this "fiscal dumping" drains tax revenue from less wealthy regions and undermines public services.

Opponents of harmonization, particularly in Madrid and the Basque Country, argue that fiscal autonomy is a constitutional right and that tax competition encourages efficiency in public spending. Madrid's regional government maintains that its lower rates attract businesses and workers, generating more overall revenue despite the lower percentage. The Basque Country and Navarre argue that their foral systems are protected by historical rights recognized in the Constitution and are not subject to harmonization.

As of 2026, no harmonization legislation has been passed at the national level, though the debate continues in every election cycle. For expats, this means that choosing where to register your tax residence remains a legitimate and impactful financial decision.

Practical Advice for Choosing Where to Register

Your tax residence is determined by where you actually live for the majority of the year (more than 183 days), not where your employer is based. However, if you have flexibility in where to establish residence, consider the following:

• Run the numbers at your salary level: The regional differences are minimal at low salaries but substantial at high incomes. If you earn over €60,000, the choice of community can affect your net salary by €1,000-€3,000 per year.
• Factor in the cost of living: Madrid may have the lowest IRPF, but it also has the highest housing costs. A lower IRPF bill may be offset by higher rent or mortgage payments. Andalusia and Valencia offer lower living costs that can compensate for slightly higher taxes.
• Consider regional deductions: If you are renting, have young children, or plan to buy property, certain communities offer deductions that could be more valuable than a slightly lower marginal rate.
• Think about Wealth Tax: If you have significant assets, Madrid's complete bonification of the Wealth Tax (effectively eliminating it) can be worth thousands of euros per year. Most other communities apply Wealth Tax on net assets above €700,000.
• Do not game the system: The tax authority (AEAT) actively investigates cases where taxpayers claim residence in a low-tax community while actually living elsewhere. False declarations carry severe penalties, including surcharges and potential criminal prosecution.

Impact at Higher Salary Levels

The regional differences become far more pronounced at higher income levels. For a worker earning €80,000 gross per year, the gap between the most and least favourable community is €1,754. At €120,000 it reaches €3,798, and at €200,000 it is €9,702 a year, close to €97,023 over a ten-year period. These are substantial sums that can affect major financial decisions such as retirement savings, property purchases, or investment strategies. For high earners, it is worth consulting a tax advisor who can model the specific numbers for your situation.
