What to watch out for
Revolving credit cards in Spain can charge up to 27% APR — often classed as usury
The Supreme Court has declared several revolving credit cards usurious at APRs more than double the legal rate. In 2026 the legal rate is 3.75%; a card with APR above ~25% may be declared null, forcing the bank to refund all interest charged. The revolving card calculator shows your debt's real cost and payoff timeline.
Pension plan contributions are capped at €1,500/year for individual plans in 2026
The IRPF deduction limit for individual pension plans is €1,500/year since 2022. Company pension plans (planes de empresa) have an additional limit of €8,500/year. The actual saving depends on your marginal rate: at 37%, each €1,000 of contributions saves you €370 in IRPF.
Spanish Treasury Bills are taxed at savings base rates, not your general IRPF rate
Returns from Treasury Bills and Bonds are taxed at the savings base: 19–28%, not at your general marginal rate.

In 2026, 12-month Treasury Bills yield approximately [VERIFY]%; check the Tesoro website for the current rate.
The FIRE number is 25× your annual spending — start calculating early

Is it better to use funds or ETFs for tax efficiency in Spain?
Spanish investment funds benefit from tax deferral on transfers: you can switch between funds without triggering a taxable event until you redeem. ETFs are taxed each time you sell. For long-term investors who regularly rebalance, Spanish domiciled funds are typically more tax-efficient. ETFs have lower costs but generate tax each time you sell.
How much will I save in IRPF by contributing to a pension plan in Spain?
The saving depends on your marginal rate. Contributing the maximum €1,500/year: at 19%, you save €285; at 30%, €450; at 45%, €675. Remember the tax is deferred — when you withdraw from the plan in retirement, it is taxed as employment income, typically at a lower rate than during your working years.
What is the difference between TIN and TAE (APR) in Spain?
TIN (Tipo de Interés Nominal) is the agreed interest rate without fees or charges. TAE (Tasa Anual Equivalente, equivalent to APR) includes interest, fees, and the compounding frequency, giving the true comparable cost. Spanish law requires all financial advertising to display the TAE. The TIN-to-TAE converter makes the exact calculation.
