I just moved to Spain not long ago and recently received my annual interest statement from the bank. That’s when I realized that in Spain, you even have to pay tax on the interest earned from your savings! I always thought putting money in the bank was the end of it, but I was wrong. I’ve done some research and wanted to share what I’ve learned, especially for fellow newcomers. Hopefully, this can help you avoid some pitfalls.
What is Savings Income Tax?
Simply put, ‘capital gains’ that are not part of your salary—such as interest from bank deposits, returns from investment products, stock dividends, profits from selling property, etc.—are subject to personal income tax, commonly known as RENTA. This portion of the tax is categorized as ‘savings income’ (rentas del ahorro) in your personal income tax return. Banks automatically report your interest income to the tax authorities each year, so it’s impossible to overlook.
How are the tax rates calculated?
Spain’s savings income tax is progressive, meaning the more you earn, the higher the tax rate. These rates, which apply to income from things like bank deposits in Spain, may be adjusted slightly each year, but the overall structure remains similar. Here is the current tax table for reference:
| Savings Income Bracket | Tax Rate |
| €0 to €6,000 | 19% |
| €6,000.01 to €50,000 | 21% |
| €50,000.01 to €200,000 | 23% |
| Over €200,000 | 26% |
For example, if your total annual income from bank interest and other investments is €7,000, the tax you owe would be calculated as follows: (€6,000 * 19%) + (€1,000 * 21%) = €1,140 + €210 = €1,350. It’s quite painful straightforward, isn’t it?

Do I need to file a tax return myself?
This is a key point. In most cases, if you only have a small amount of interest from bank deposits, the bank will have already withheld 19% tax when paying you the interest. You can check your bank statement for an item called ‘Retención IRPF’ or similar. However, this doesn’t mean you can ignore it. When you file your annual personal income tax return (RENTA) between April and the end of June, you need to include this income and the amount already withheld. The tax agency will then calculate your final tax liability based on your total income, and you’ll either receive a refund or have to pay the difference.
In Spain, tax matters should not be taken lightly. Although the tax on bank interest might not be a large amount, understanding the rules and filing on time is crucial for a worry-free life here.
