How are income taxes calculated in Spain?

Income tax in Spain is calculated based on a progressive tax system, where the tax rate increases as the taxable income increases. This system applies to both residents and non-residents, although the specific rates and allowances may differ. Here’s a general overview of how income taxes are calculated for residents:

For Residents:

Residents of Spain are taxed on their worldwide income, which includes employment income, income from self-employment, capital gains, and income from property, among others.

General Tax Base: This includes most types of income, such as employment income, self-employment income, and pension income.
Savings Tax Base: This includes income from savings and investments, such as interest, dividends, and capital gains from the sale of assets.

The tax rates are progressive, with different bands applying to different portions of income. As of my last update, the general tax rates for state taxes range from about 19% to 45%, with additional regional variations that can change the overall rates slightly, as Spain’s autonomous communities have the authority to adjust the state tax rates within their jurisdiction.

For the savings income (capital gains and investment income), the tax rates are also progressive but usually have fewer bands, starting at 19% and going up to 26% for higher amounts of investment income.

Tax Allowances and Deductions:

Personal Allowance: Residents receive a basic personal allowance that reduces taxable income, which can be higher for individuals over 65 or 75 years of age.
Deductions for Family Situations: Additional allowances may be available for taxpayers with children, dependents with disabilities, or those paying alimony.
Other Deductions: Taxpayers can also deduct certain expenses, such as contributions to pension plans, home purchase interest (under specific conditions and subject to change), and educational expenses, among others.

Dual Tax Rates:

Spain uses a dual income tax system, where general income and savings income are taxed at different rates. Each type of income is aggregated within its category, and then each category is taxed according to its own scale.

Non-Residents:

Non-residents are taxed only on their Spanish-source income. The non-resident tax rate is generally flat, with a standard rate of 24% for employment income, though this rate can vary for EU/EEA residents, who might be taxed at a lower rate on certain types of income.

Filing Tax Returns:

Residents and non-residents with tax obligations must file an annual income tax return. The tax year in Spain is the calendar year, with tax returns generally due by the end of June for the previous year's income.

It's important to note that tax laws and rates can change, and there may be specific rules and conditions that apply to individual situations. Therefore, consulting a tax professional or the Spanish Tax Agency (Agencia Tributaria) for personalized advice and the latest information is advisable.
