If you live in Spain, choosing between index funds in Spain and ETFs is not just a question of fees. Spanish tax law gives ordinary investment funds a special advantage that ETFs do not have: you can move your money from one fund to another without paying tax on the gain. That single rule shapes how most Spanish passive investors build their portfolio.
In short
- Index funds can be switched with a traspaso: no tax until you finally sell.
- ETFs cannot use traspasos. Every sale is a taxable event.
- Gains are taxed in the savings base at 19% to 30% in 2026.
- With more than €50,000 at a foreign broker, you must file the informative Modelo 720.
What a traspaso is
A traspaso is a direct transfer from one investment fund to another. Under the Spanish income tax law (article 94 of the LIRPF), the gain on the old fund is not taxed at that moment. Instead, it carries over to the new fund with the original purchase value and date. You only pay tax when you finally sell and take the money out.
For a long-term investor, this matters a lot. You can change provider, move from a world fund to a cheaper one, or rebalance between equities and bonds without handing part of your gains to Hacienda each time. The tax is deferred, not cancelled, but deferral lets the full amount keep compounding.
There are conditions. The fund must be a UCITS fund domiciled in the EU and registered with the CNMV for sale in Spain, and the money must go directly from one fund to the other. If the cash passes through your bank account, the deferral is lost.
Why ETFs do not get the same treatment
ETFs are also investment funds, but Spanish rules exclude them from the traspaso regime in both directions. If you sell an ETF to buy another one, you pay tax on the gain in that year’s tax return. The same happens if you want to move from an ETF to an index fund.
This does not make ETFs a bad choice. If you plan to buy one global ETF and hold it for decades, you may never need to switch. But if you expect to rebalance or change products, index funds give you flexibility that ETFs cannot. For the basics of both products, see index investing for Europeans.
Index funds in Spain vs ETFs at a glance

Popular global index funds in Spain
Most Spanish investors build their core with a fund that tracks the developed world or the whole world. Two common examples, available through Spanish platforms such as MyInvestor, are:
- Fidelity MSCI World Index Fund P-Acc-EUR (IE00BYX5NX33): about 0.12% a year, developed markets only.
- Vanguard Global Stock Index Fund Investor EUR Acc (IE00B03HCZ61): about 0.18% a year, developed markets only.
Both accumulate their dividends, which suits Spanish tax rules, because you are not taxed on income you never receive. To add emerging markets, many investors combine a world fund with a small emerging markets index fund. Always check the fund’s current costs in its KID before buying.
How gains are taxed in 2026
Gains from selling funds or ETFs, together with dividends and interest, go into the base del ahorro. In 2026 the rates are:
| Savings income | Rate |
|---|---|
| Up to €6,000 | 19% |
| €6,000 to €50,000 | 21% |
| €50,000 to €200,000 | 23% |
| €200,000 to €300,000 | 27% |
| Above €300,000 | 30% |
When you redeem a Spanish-registered fund with a gain, the fund company withholds 19% as an advance payment. You then settle the final amount in your annual return. Losses can be offset against gains of the same year, and a remaining loss can be carried forward for four years.
Navarra and the Basque Country apply their own savings scales, so check the rates if you live there.
Selling at a loss and buying back
Spain has an anti-avoidance rule for losses. For listed securities such as ETFs, if you sell at a loss and buy the same product within two months, you cannot use that loss until you sell the new shares. For ordinary investment funds, official positions on the two-month rule have been inconsistent, so the cautious approach is to wait longer before buying the same fund back. If loss harvesting is part of your plan, ask a tax adviser first.
Modelo 720: holding money abroad
If you use a foreign broker or bank, such as a German or Irish one, you must file the informative Modelo 720 when the value of your securities held abroad exceeds €50,000 at the end of the year. It is a declaration, not a tax: it tells Hacienda what you hold. You still report gains and dividends in your normal income tax return.
Funds bought through a Spanish platform are generally reported by the Spanish entity, which is one reason many investors keep their index funds at home and only use foreign brokers for ETFs.
A simple setup for Spanish residents
- Keep an emergency fund in a savings account or deposit first.
- Open an account with a Spanish platform that offers low-cost index funds.
- Pick one global equity index fund, or a world fund plus a small emerging markets fund.
- Set up an automatic monthly contribution.
- Use traspasos, not sales, whenever you want to change funds.
If you would rather use ETFs, the logic of the best all-world ETFs still applies; just accept that switching later will cost tax. For how other countries compare, read how ETFs are taxed in Europe.
