Plusvalía municipal is the seller's second tax, and the one people remember last. Its full name is Impuesto sobre el Incremento de Valor de los Terrenos de Naturaleza Urbana: a tax on the increase in the value of the land under the property. Not of the flat — of the land, the share of it that belongs to your flat. It is paid to the town hall, has nothing to do with the tax on your gain, and is calculated on its own rules.
The thing worth knowing before the sale: there are two methods of calculation, and the law lets you take whichever produces the lower figure. On the same flat the difference between them can be several times over. Nobody will calculate both for you unless you ask.
Two methods: objective and real
The objective method does not look at your transaction at all. It takes the cadastral value of the land — not of the whole property — at the date of sale, and multiplies it by a coefficient that depends on how many years you owned it. For 2026 the coefficients run from roughly 0.13 to 0.20 and are approved annually. The rate is then applied to that base: in Barcelona, 30%.
The real method looks precisely at your transaction: the difference between the sale price and the purchase price, of which it takes the proportion that the land represents in the cadastral value of the property. The same 30% then applies.
| Objective method | Real method | |
|---|---|---|
| The base | Cadastral land value × coefficient for years of ownership | Difference in prices × the land's share of cadastral value |
| Depends on your sale | no | yes |
| Better when | the property rose a lot in value | it rose little or not at all |
| Rate in Barcelona | 30% | 30% |
There is no trick in this: both are calculated, and the lower one is paid. The trick is that both have to be calculated by you — or by your gestor — and not by the town hall.
If the property did not rise in value, there is no tax
That follows directly from the Constitutional Court's 2021 ruling: the tax is levied on an increase in value, and where there was no increase there is no tax. Sell for the same sum or less than you paid, and there is nothing to pay.
But the exemption does not operate by itself. It has to be claimed and proved: the purchase deed and the sale deed, both produced to the town hall. Without that the town hall will calculate on the objective method, which is indifferent to your transaction, and issue an assessment.
The deadline: 30 working days
In Barcelona you have 30 working days from the date of the notarial deed to file and pay. Working days: Saturdays, Sundays and public holidays drop out, while the whole of August counts.
It is filed with the Institut Municipal d'Hisenda, in person or through the town hall's electronic office. Outside Barcelona the period is the same — 30 working days on a sale — but each town hall sets its own rules and rates: in the Maresme or on the Costa Brava it will be the town hall of the municipality the property stands in.
Filing late attracts a surcharge of between 5% and 20%, depending on how late.
A non-resident seller: the buyer pays
A separate rule, and one that is rarely written about in English. Under the local taxation act the taxpayer on plusvalía is the seller — but where the seller is not resident in Spain, the buyer becomes the taxpayer. The law calls this the "substitute taxpayer" (sustituto del contribuyente): the town hall collects from the party who remains in the country.
It still comes out of your money. The same law entitles the buyer to recover what they paid from you, and in practice the sum is simply deducted from the price on the day of signing. What changes is not really who bears it, but the order of events — and who ends up holding the proof of payment.
What that means in practice:
- The buyer knows about it, or will learn it from their lawyer before the deposit, and will certainly factor the sum into the negotiation.
- The parties can agree who bears the cost economically and write that into the deposit contract (arras). The buyer remains the one answerable to the town hall regardless.
- It is sensible to have the figure calculated before you agree a price, not after. Otherwise the buyer will calculate it — and deduct it from your price, rounded in their favour.
An example, to see the gap
The figures are illustrative and exist only to show how far apart the two methods can fall. A flat in the Eixample: bought in 2016 for €400,000, sold in 2026 for €460,000. The cadastral value of the land is €90,000, and land accounts for 55% of the property's cadastral value.
| Method | Calculation | Tax |
|---|---|---|
| Objective | €90,000 × the coefficient for 10 years of ownership, then 30% | around €4,000 |
| Real | (€460,000 − €400,000) × 55% = €33,000, then 30% | €9,900 |
Here the objective method is cheaper. But a different price history — a purchase at the 2007 peak and a sale with a modest rise, for instance — turns the picture over. Which is why both have to be calculated, rather than whichever is quoted first.
Frequently asked questions
Who pays plusvalía on a sale?
As a general rule, the seller. But where the seller is not resident in Spain, the buyer pays it as the "substitute taxpayer". Who bears the cost economically is usually settled between the parties in the deposit contract.
How much is it in money?
Anywhere from a couple of thousand to several tens of thousands of euros, depending on the cadastral value of the land, the length of ownership and the difference in prices. The exact figure for a particular property is calculated by a gestor, and it is worth having before you go to market.
I am selling for less than I paid. Definitely nothing to pay?
There will be no tax, but the return still has to be filed, with both deeds attached. The town hall does not read silence in your favour.
Can I pay later?
The deadline in Barcelona is 30 working days from the notarial deed. After that a surcharge of 5% to 20% applies. The town hall does grant instalments in some cases, but that is a separate application.
Is this the same as the 19% tax on the gain?
No. They are two different taxes: plusvalía is municipal, on the increase in land value, and paid to the town hall; the tax on the gain is a state tax, 19% for a non-resident, paid to the Agencia Tributaria. Both are payable.
And if the property is not in Barcelona?
The mechanics are the same, but each town hall sets its own rate and coefficients. In the Maresme or on the Costa Brava the calculation follows that municipality's rules — and the filing deadline should be checked there too.
The two taxes, together with the commission and the cost of the documents, decide what you actually end up with. I calculate that figure before the property goes to market, not after a buyer has been found: how a sale runs, and what is needed from you, is set out step by step. The easiest place to start is the price — send me the address and the floor area and I will reply within one or two working hours.
