What actually changes from one autonomous community to another?

Key rules

• National rules: Immigration, residence and work permits, and most labour law are the same in every region.
• Regional rules: Health services, schools, housing policy, language of teaching and part of income tax are set or run by your community.
• Basque Country and Navarre: These two have their own tax regime, so the common regional tax comparisons do not apply to them.

The short answer

Health, education, some taxes, housing policy and language are devolved or shared between the national government and the autonomous communities. Immigration and most labour law are national. Your residence permit and work rules are the same wherever you live. Your daily life (doctor, school, tax bill) can differ a lot.

What is the same everywhere

• Immigration and residence. Visas, residence permits, work permits, nationality and asylum are all national. Region does not change what you qualify for.
• Most labour law. The State writes the rules on contracts and employment. Communities mostly run services, such as public employment services and some inspection work.
• Social Security and pensions. These are national.
• Courts and general tax law. These are national too.

What changes by region

Housing policy. Urban planning and housing are largely regional. Local support schemes, planning rules and public works vary, so ask your community and town hall.

Health. The State sets a common basket of services that every community must provide. Communities run the services and may add extras from their own funds, such as more dental care, vaccines or wider access to assisted reproduction. Your tarjeta sanitaria is issued by your community's health service once you register at your local health centre with your padrón registration and Social Security number. It can be used in other communities. Prescription co-payments are set nationally, but some communities, such as Galicia and the Basque Country, add their own income-based caps or exemptions. Waiting times differ widely between communities.

Schools. The State sets the minimum curriculum. It takes 50% of school hours in communities with a co-official language and 60% in those without one. Communities set the rest, plus the calendar and admission rules. Admission criteria are broadly similar (siblings, home proximity, family income, disability), but each community sets its own points and school zones. This applies to public and state-subsidised schools. Private schools have more freedom.

Language. Catalonia, the Basque Country, Galicia, Valencia, the Balearics and part of Navarre have a co-official language used in teaching. The models differ. Catalonia uses Catalan as the main language, with a court-ordered minimum share of Spanish. The Basque Country has models A, B and D. Galicia sets minimum shares by decree. Spanish is always taught. Getting schooling mainly in Spanish where the regional language leads can require court action in some places.

Taxes. Income tax (IRPF) is split between the State and the community. Each community sets its own scale and deductions for its share, which is about half. Top combined rates run from roughly 43-45% in places like Madrid to about 50% in Catalonia, and about 50-54% in places like Valencia, Asturias and Cantabria. Regional deductions can cover births, rent for young people, large families and disability. Communities also manage inheritance, gift and wealth taxes and transfer tax, with their own rules. The Basque Country and Navarre have their own tax regime.

How to use this

Treat the national rules as fixed, then compare the regional ones that affect you most: the school if you have children, the health service if you have ongoing care, and the tax if you have high income or assets. The decision, checklist and FAQ below help you with these.

Choosing between options

How should regional income tax weigh in on where you settle?

• Treat tax as a deciding factor: Your income is high, since the combined top rate runs from roughly 43-45% in places such as Madrid to 50-54% in places such as Catalonia, Valencia, Asturias and Cantabria.

• Treat tax as a minor factor: Your income is modest or housing, schools, health services or language matter more to you, since regional differences then change your tax bill little.

• Look at deductions first: You have a newborn, a large family, a disability or are a young renter, since regional deductions can matter more than the rate.

You are taxed by the region where you spent the most days in the tax year, and that region's tax rules apply for the whole year.

Regional income tax rates are approximate and change often. Check the current scales with the tax agency before deciding.

Checklist

• Treat immigration, residence and work permits as national: check them with the national authorities, whichever region you choose.

• Look up your community's Statute of Autonomy, or its regional government website, to see which powers it has taken on for housing, social services, tourism and language.

• Ask your community's education department for its admission points system and school zones before choosing where to live.

• Check whether your community has a co-official language and which language model its public and state-subsidised schools use.

• Check your community's regional income tax scale and deductions, such as births, young renters, large families and disability.

• Find out whether your community has its own tax rules for wealth, inheritance and gift tax, or whether the Basque Country or Navarre regime applies.

Frequently asked questions

Does my health card work if I move to another region?

Yes, the national system lets you use a card from one community in another. Each community issues its own card, though, so you register at your local health centre with your padrón certificate and Social Security number.

Why do some regions cover extra health services?

Every community must offer the same common basket of services.

Will my child be taught in Spanish or the regional language?

In communities with a co-official language, your child will usually be taught largely in the regional language, with Spanish taught as a subject. The model differs by region, and schooling mainly in Spanish may only be possible through a court case in some places.

Does my income tax really change by region?

Yes, because each common-regime community sets its own scale and deductions for its share, so the top combined rates can differ by several points. The Basque Country and Navarre run a separate system.
