The 3% Retention in Spain: Modelo 211 for Non Resident Sellers

Why the buyer pays it, and not you

This is the part that catches almost everyone off guard. Capital gains tax on a Spanish property sale is, in principle, the seller's responsibility. But Spain has a practical problem with non resident sellers: once the money lands and the seller leaves, chasing them for tax owed becomes difficult, expensive, and often pointless. So the law shifts the job of collecting a first slice of that tax to someone Spain can actually reach, the buyer, who is usually still in the country, dealing with a notary, and easy to hold accountable.

At completion, the buyer does not pay you the full price and then trust you to sort out the tax later. They calculate 3% of the total agreed price, keep it back, and pay it directly to the tax authorities on your behalf using Modelo 211. You receive the remaining 97%. Think of Marieke and Tom, a Dutch couple selling their apartment near Alicante for 220,000 euros. At the notary, the buyer transfers 213,400 euros to their account and pays the remaining 6,600 euros straight to the Agencia Tributaria. Marieke and Tom never touch that 6,600 euros, and they do not need to, because it was never meant to be theirs to keep. It is an advance on tax they may or may not actually owe.

Not an extra tax. A deposit against what you actually owe

The single most important thing to understand about the 3% is what it is not. It is not a final tax, and it is not calculated on your profit. It is calculated on the entire sale price, gross, regardless of whether you made a fortune on the property or barely broke even. Spain calls this a payment on account, an advance against whatever your real capital gains liability turns out to be once it is properly calculated.

That real liability is worked out differently, and later. Your actual capital gains tax is based on your gain, the sale price minus your documented acquisition cost, the purchase taxes you paid when you originally bought the property, any proven improvement costs, and your selling costs such as agency and legal fees. Once that gain is calculated, it is taxed at 19% if you are a tax resident of the EU or the EEA, or 24% if you are not. That gap between 19% and 24% matters more than people expect, and it means two sellers with an identical gain can end up owing genuinely different amounts depending on where they live.

How Modelo 211 actually works behind the scenes

The mechanics sit almost entirely on the buyer's side, which is part of why sellers rarely understand them. Within one month of completion, the date you sign at the notary, the buyer is required to file Modelo 211 and pay the 3% they withheld directly to the Agencia Tributaria. In practice, this is usually handled by the buyer's notary or legal advisor as part of closing the sale, not something the buyer does personally from a tax office queue.

Once it is filed and paid, the buyer must give you a stamped copy of Modelo 211. This is not a courtesy. It is your proof that the withholding actually happened and actually reached the tax authorities, and you will need it later to claim credit for that amount against your own capital gains tax. If that stamped copy does not turn up at completion, ask for it. Without it, reclaiming your share of that 3% becomes far more complicated than it needs to be.

If you made little profit, or none at all, you still lose the 3% first

Because the withholding is calculated on the gross price rather than on any profit, it applies even to sellers who made barely any gain, or who are actually selling at a loss. This surprises people constantly, and it is worth sitting with for a moment, because it feels deeply unfair on the surface.

Take Klaus, a German retiree who bought a finca near Ronda for 300,000 euros back in 2007, right before the market turned. In 2026 he finally sells it for 280,000 euros, a loss of 20,000 euros in nominal terms. He has made no gain at all, and technically owes zero capital gains tax. Yet the buyer still withholds 3% of 280,000 euros, which is 8,400 euros, and pays it to the Agencia Tributaria, exactly as the law requires. Klaus does not get that money back automatically. He has to go and claim it.

Getting the money back, or paying the difference, through Modelo 210

This is where the seller finally does their own paperwork. You file Modelo 210 to declare your real capital gain, the true sale price minus your costs, and to work out what you genuinely owe. Whatever the Agencia Tributaria already collected through the buyer's Modelo 211 is treated as a credit against that final number.

If the 3% withheld turns out to be more than you actually owe, which is common when there is little gain, no gain, or an outright loss, you claim a refund of the difference through that same Modelo 210 filing. Klaus, from the example above, would file Modelo 210 showing a loss, and reclaim the full 8,400 euros that was withheld, since he owes nothing.

If the 3% withheld is less than what you owe, you pay the balance alongside the same filing. Picture Sarah, a British seller who is not an EU or EEA tax resident since Brexit, selling a townhouse in Mallorca she bought for 250,000 euros and now sells for 300,000 euros, a gain of 50,000 euros. At her 24% rate, she owes 12,000 euros in capital gains tax. The buyer withheld only 9,000 euros, 3% of the 300,000 euro price, so Sarah owes the Agencia Tributaria a further 3,000 euros when she files her Modelo 210.

Now compare that with Anke, a German seller and therefore an EU tax resident, who bought an apartment in Torrevieja for 180,000 euros in 2015 and sells it in 2026 for 210,000 euros, a gain of 30,000 euros. At her 19% rate, Anke owes 5,700 euros. The buyer withheld 6,300 euros, 3% of the 210,000 euro price, so Anke is due a refund of 600 euros once her Modelo 210 is processed. Whether you end up owed money or owing more depends entirely on your own numbers, your residency, and how large your real gain actually is, so it is worth working through your own figures before you assume either outcome.

Budgeting for completion day, because your proceeds will be lighter than the headline price

The practical lesson here is simple, and it matters more than the legal explanation. Whatever the sale price on your contract says, do not plan your finances around receiving that full amount at completion. You will receive 97% of it in your account, and the remaining 3% goes straight to the tax authorities before you ever see it. If you are relying on the full proceeds to fund a purchase elsewhere, cover moving costs, or simply pay off a debt, build that 3% gap into your planning from the start, not after you are standing at the notary wondering where the rest of your money went.

The second lesson is just as important. Even if you expect a refund because your real gain is small or nonexistent, that money is not lost, but it is also not instantly available. It sits with the Agencia Tributaria until you file Modelo 210 and the refund is processed, so treat it as money you will get back in time, not money you can spend the week after completion.

What happens if the buyer does not withhold

Occasionally a buyer, usually through inexperience rather than intent, fails to withhold and pay the 3% correctly. When that happens, Spanish tax law does not simply let the debt disappear. It can attach the unpaid amount to the property itself, a concept known as affeccion real, meaning the tax authorities can pursue the property to recover what is owed, even from a future owner who had nothing to do with the original sale.

This is exactly why experienced notaries and careful buyers treat Modelo 211 as non negotiable rather than optional paperwork. A buyer who skips it is not just risking a penalty for themselves, they are leaving a cloud over the property they just bought, which is the last thing anyone wants hanging over a purchase they plan to keep or resell later. If you are selling, it is worth confirming your buyer, or their notary, actually files and pays on time, and that you receive your stamped copy as proof.
