Selling as a non-resident: the 3 % retention and the plusvalía

Every buying guide tells you what a purchase in Spain costs. Far fewer people explain what happens on the other side of the table — and for a non-resident seller in Costa Adeje or Corralejo, the selling side has its own arithmetic, run by two taxes that behave nothing like each other. One takes 3 % of your price before you ever see it. The other lands, by law, on your buyer — and both reward the seller who arrives at the notary with a complete paper file.

This piece is the mirror of our guide to buying property: same table, opposite chair. Here is how the money actually moves when a non-resident sells, what the deadlines are, and where refunds are won and lost.

The 3 % that never reaches you

When the seller of a Spanish property is a non-resident without a permanent establishment, the law makes the buyer do something counter-intuitive: keep back 3 % of the agreed price and pay it to the tax office — not as a cost of their own, but on account of your tax as the seller. The buyer files it with form (modelo) 211 within one month of the deed, and hands you a copy of the filing: guard that copy, because your refund claim will be built on it.

Two features make this mechanism impossible to shrug off:

• It is not optional, and it is not negotiable. The only way out is not being in its scope at all — a seller who is actually a Spanish tax resident and proves it with an AEAT residence certificate is not retained.
• The property itself answers for it. If the retention is not paid in, the transferred property remains liable for the lesser of the retention and the tax due, and the land registrar notes that charge in the margin of the registration. That is why no well-advised buyer will ever skip the 3 % — and why a seller should not expect to talk them out of it.

Modelo 210: settling the real bill

The 3 % is a prepayment, not the tax. The real tax is calculated on your actual capital gain, declared by you — the seller — on form 210, within three months counted from the end of the buyer's one-month window (in practice, about four months from the deed).

The arithmetic is classical:

• Transfer value: the price, minus the costs and taxes of the sale that you bore (agency commission, legal fees, the plusvalía if you contractually assumed it).
• Acquisition value: what you paid when you bought, plus the taxes and costs of that purchase (ITP or VAT, notary, registry) plus documented improvements — invoiced works, not redecorating.
• The difference is taxed at 19 % for non-resident individuals.

Then the 3 % meets the 19 %:

• Gain large → the retention falls short and the 210 shows a top-up to pay.
• Gain small → the retention overshoots and the 210 becomes a refund claim.
• No gain at all — you sold at or below your acquisition value — and the whole 3 % comes back. Selling at a loss does not spare you the paperwork; it is precisely the paperwork that gets your money returned.

Getting the refund — and not waiting longer than you must

Refunds are real, but they are reviewed, not rubber-stamped, and the review is a documents game. The claims that come back fastest are the ones filed complete on day one: both deeds, the invoices behind every cost you deducted, the buyer's 211 copy, and proof of a bank account for the payment — keeping a Spanish account open until the refund lands spares a surprising amount of friction, and if you claim under a tax treaty, a certificate of tax residence from your home authority belongs in the file. Expect the Administration to take months rather than weeks; expect a requerimiento (a demand for more papers) if anything is missing, and answer it within its deadline or the clock restarts against you.

One planning note while the file is open: the sale usually ends your other Spanish tax story too — the imputed-income or rental filings of your ownership years should be up to date, because a refund review looks at the whole picture.

The plusvalía after the 2021 reform

The second tax is municipal: the IIVTNU, universally called plusvalía, charged by the town hall on the increase in the value of the urban land (not the building) while you owned it.

Its modern shape dates from late 2021, when the Constitutional Court struck down the old calculation method and a royal decree-law rebuilt it. Two rules matter to a seller today:

• You choose between two methods: an objective calculation (coefficients set by the town hall, by holding period, applied to the land's cadastral value) or the real method (the actual land gain derived from your two deeds). You are entitled to whichever is lower — run both before anyone files.
• No increase, no tax. If your deeds show the land value did not rise, the transaction is simply not taxed — but that result must be declared and proven, not assumed.

Deadlines are municipal, but the general rule for sales is a declaration within 30 working days of the transfer — short enough that it should be organised before the notary appointment, not after.

When the seller is non-resident, the buyer steps in

Here is the twist most foreign sellers have never heard: for the plusvalía, when the seller is a non-resident, the law designates the buyer as substitute taxpayer. The town hall addresses the bill to the buyer, and the buyer — not you — must file and pay it.

In practice, buyers protect themselves: the estimated plusvalía is calculated before completion and retained from the price or settled at the notary's table, with the deed recording who bears what. Handled well, this is routine; handled vaguely, it is the classic post-completion dispute. As a seller, insist that the deed states the exact figure withheld and the method used — and remember that being the substitute's economic burden does not stop you from arguing the no-increase rule if the numbers support it.

The paperwork that decides the arithmetic

Every euro in this story is proven, not asserted. The file that a well-run non-resident sale carries to the notary:

• Your acquisition deed and the invoices for its taxes and costs — they raise your acquisition value and shrink the taxed gain.
• Invoices for improvement works — licensed, invoiced works count; a folder of receipts from a reform without paperwork does not.
• The selling costs — agency, lawyers, energy certificate — with invoices in your name.
• Cadastral and IBI receipts — the land's cadastral value drives the objective plusvalía method.
• Your residence status, documented — if you are in fact a Spanish tax resident, the AEAT certificate removes the 3 % retention entirely; if you are not, a home-country residence certificate supports any treaty claim.
• Narrow exemptions exist around the edges — for instance for certain EU/EEA residents reinvesting the proceeds of what was once their main home — but they are condition-heavy: have your case checked before you count on one.

A seller's five-point check

• Reconstruct your acquisition file early — deed, taxes, invoices. Weeks before listing, not the night before completion.
• Model the two taxes in advance: 19 % on the documented gain, and both plusvalía methods — so the notary-day retentions hold no surprises.
• Agree the plusvalía mechanics in writing — who retains what, under which method, stated in the deed.
• Keep the buyer's 211 copy and a live bank account for the refund.
• Diary the 210 window — three months after the buyer's month. Miss it and the refund path turns uphill.

In a non-resident sale, the price is what you agree. What you keep is what the paperwork proves.

Common questions

Is the 3 % retention the tax I owe on the sale?

No — it is a prepayment taken from your price on account of the real tax, which is 19 % of your actual gain, declared on form 210. Depending on the numbers, you will either top up the difference or claim part or all of the 3 % back.

I am selling at a loss. Do I get the 3 % back — and what about the plusvalía?

Yes, on both fronts, but each has its own proof. The 3 % comes back through a form 210 refund claim built on your two deeds and cost invoices. The plusvalía disappears only if the deeds show no increase in land value — a result that must be declared to the town hall, not assumed.

Who pays the plusvalía when the seller is non-resident?

Legally, the buyer, as substitute taxpayer — the town hall bills them. Economically, it is settled between the parties, usually by retaining the estimated amount from the price at completion. Make the deed say exactly what was withheld and why.

What are the deadlines, in one breath?

The buyer files the 3 % (form 211) within one month of the deed. You file form 210 within the following three months. The plusvalía declaration is generally due within 30 working days of the transfer. All three are shorter than they feel from abroad — organise them before completion.

The buyer never paid in the 3 %. What happens?

The law's answer is drastic: the property itself remains liable for the lesser of the retention and your tax, with a marginal note at the land registry — which is the buyer's problem and their lawyer's nightmare. Your own duty to file the 210 stands regardless, so do not let their omission become your default.
