Funds versus ETFs: why Spanish tax treatment differs

Key rules

• Traspaso: Only qualifying Spanish funds allow a tax-free switch, and only if the money never passes through your hands.
• ETFs and foreign funds: Every sale and switch is taxable, even between UCITS funds.
• US ETFs: European brokers usually block retail purchases because of the missing PRIIPs KID.

The short answer

Only qualifying Spanish funds let you switch investments without paying tax at the time. Selling an ETF or a foreign fund and buying another is taxed every time. US-domiciled ETFs are usually not available to you at all through a European broker.

How the tax-free switch works

A switch between Spanish funds is called a traspaso. You pay no tax when you move. The gain or loss is deferred, and the original cost and purchase date carry over to the new fund. Tax is due only when you finally sell and take the money out.

The traspaso works only if:

• You are the holder of the units.
• Both funds are Spanish-registered collective investment funds, mainly UCITS-type funds and qualifying SICAVs.
• The money goes straight from one fund to the other. If it lands in your bank account first, you have made a taxable sale.

It also covers buying a fund unit with money from selling another qualifying fund.

What is taxed on every switch

Selling one ETF and buying another is a taxable sale. So is switching between foreign-domiciled funds, even if they are UCITS funds. The gain or loss counts as a capital gain or loss in the savings base of your income tax return, and you must declare it.

Foreign-domiciled funds held outside Spain may also need a Modelo 720 declaration above the thresholds. The threshold and how to file are covered in the tax pages.

A change since 2025 extends deferral to switches between Spanish-regulated ETFs, under conditions. Check with your broker or a tax adviser that your specific products qualify before you rely on it.

Why US ETFs are usually blocked

US-domiciled ETFs generally lack the PRIIPs Key Information Document (KID) that European retail investors must receive. So EU brokers usually block you from buying them. Their UCITS equivalents, often domiciled in Ireland or Luxembourg, are available. Some brokers outside the EU still sell US ETFs, and professionally classified clients can sometimes buy them. Policies differ by broker, so ask before you open an account.

How to choose

• If you expect to rebalance often and want to defer tax, Spanish funds are the tidy option.
• If you prefer ETFs, accept that each switch triggers tax, and keep records of costs and dates.
• If you want a US ETF, look for the UCITS version of the same index.

How the vehicles compare

Switching between funds is where they differ most. A Spanish fund lets you move your money to another fund without paying tax at that moment. An ETF or foreign fund does not.

Conditions for deferral

• You must be the holder of the units.
• The money must go straight from one eligible fund to another. It must never pass through your hands.
• The deferral also applies if you use the proceeds of a sale to subscribe to a fund.
• It does not cover ETFs traded on an exchange, or foreign-domiciled funds (even UCITS ones), except in certain cases.

Check with your fund provider whether the 2025 extension covers the specific ETF you hold.

Insurance policies and foreign tax shelters

Tax treatment on withholding, deferral and reporting for insurance policies and foreign tax shelters depends on the product. Before you buy one, ask a Spanish tax adviser how it is taxed for a Spanish resident.

Frequently asked questions

Does the tax-free traspaso work if the money passes through my bank account?

No, the traspaso only works if the money goes straight from one eligible fund into another without passing through your hands. You must also be the holder of the units, and both funds must be Spanish-registered. The same deferral applies when you subscribe to a fund unit with money from a sale.

Can I switch between Spanish-regulated ETFs without paying tax?

Since 2025, switches between Spanish-regulated ETFs can also be deferred, but only under conditions. Check with your broker that your specific products qualify before you switch. ETFs bought on an exchange in the usual way still trigger tax on a sale.

Can I buy a US-domiciled ETF through my European broker?

Usually no, because EU brokers generally block retail purchases of US-domiciled ETFs. Issuers do not publish the key information document (KID) that retail clients must receive. Look for an equivalent UCITS ETF, often Irish or Luxembourg-domiciled, instead.

Is a UCITS fund from another country treated like a Spanish fund for traspaso?

No, a foreign-domiciled fund does not get the traspaso deferral even if it is a UCITS. Switching out of it is a taxable sale, and the gain or loss goes in your savings income. You may also need to report it as a foreign asset.
