ETF vs mutual fund taxes in Spain
Why a Spanish resident can switch between mutual funds without paying tax, why ETFs usually cannot, and the savings tax bands that apply when you sell.
Gains are taxed when you sell
For a Spanish tax resident, gains on funds and ETFs go in the savings part of personal income tax (IRPF). Dividends paid by distributing funds are taxed in the year you receive them. Accumulating funds reinvest income, so you pay nothing until you sell.
Savings tax bands (from 2025)
19% up to 6,000 EUR; 21% from 6,000 to 50,000 EUR; 23% from 50,000 to 200,000 EUR; 27% from 200,000 to 300,000 EUR; 30% above 300,000 EUR. Banks and fund managers usually withhold 19% on gains and dividends in advance, and the difference is settled in your annual return.
Fund switches (traspasos)
Moving money from one mutual fund to another without cashing out defers the tax: the gain is only taxed when you finally sell (article 94 of the IRPF law). This applies to funds registered with the CNMV, and to foreign funds marketed in Spain with at least 500 investors, when the switch is done through the managers.
ETFs
Listed ETFs are excluded from the switch regime, so selling one ETF to buy another is a taxable sale. Gains on ETFs traded on Spanish exchanges have no withholding when sold. Foreign-domiciled ETFs (for example Irish UCITS) are also taxed on sale and their income can carry foreign withholding.
In short
Long-term investors who expect to rebalance or change provider often prefer index mutual funds for the tax-free switch. ETFs can be cheaper and trade during the day, but each change is a taxable event. Check your own situation with the AEAT or an adviser.
