What it is, for anyone meeting it for the first time
Spain taxes the sale of a property twice, at two different levels of government, and the two have nothing to do with each other. The state taxes your capital gain through income tax — through form 210 if you are not resident here. Separately, the town hall taxes the increase in the value of the land under the building. Its formal name is the tax on the increase in urban land value; everyone calls it the plusvalía.
Two things follow from that definition. It taxes land, not bricks: a flat on the eighth floor still carries a share of the plot beneath it, and that share is what is taxed. And it taxes an increase: if there was no increase, there is nothing to tax.
The figures come from the cadastre, the national property register that assigns every building and plot an administrative value for tax purposes. Your annual council rates bill — the IBI, which every owner in Spain receives once a year — shows that cadastral value split between land and building. That split is the number this whole tax turns on, and it is why the first document we ask for is the IBI receipt.
The two methods, since the law was rewritten
Judgment 182/2021 of the Constitutional Court annulled the calculation method that had been applied for decades, and Royal Decree-Law 26/2021 replaced it with two alternatives. Since then:
| Method | How it is worked out | When it wins |
|---|---|---|
| Objective | Cadastral value of the land × a coefficient set by the number of years you owned it | Where the real gain was large |
| Real | (Sale price − purchase price) × the proportion the land represents in the cadastral value | Where the gain was small or nil |
The law lets the taxpayer apply whichever method produces the lower result. Where a town hall has issued an assessment on the objective method without comparing, you can ask for it to be corrected. Running both calculations takes five minutes and routinely saves several hundred euros.
No increase in land value, no tax
Where the land has not gone up in value, the taxable event does not arise at all. Proving it is usually a matter of putting two documents side by side:
- The two deeds. If the sale price does not exceed the purchase price, there is nothing to pay.
- In an inheritance, the comparison is made against the value declared for inheritance tax purposes, which is why that figure should never be chosen carelessly.
- The acquisition figure can often be increased by the costs and taxes you bore on buying, although town halls take different views on this and the case law runs both ways. It is worth arguing and not worth assuming.
- If you have already paid and there was no gain, you apply for a refund of tax wrongly paid. The window is four years.
Who pays it, and by when
| Transaction | Who is liable | Deadline |
|---|---|---|
| Sale | The seller | 30 working days |
| Sale where the seller is not resident in Spain | The buyer, as substitute taxpayer | 30 working days |
| Gift | The person receiving | 30 working days |
| Inheritance | The heirs | Six months, extendable to twelve |
Each town hall has its own by-law, its own rate — up to 30 % — and its own reliefs, which for the family home passing on death can be very large indeed. That is why the first document we read is not the statute but the by-law of the particular municipality. Two identical flats in neighbouring towns can produce bills that differ by a factor of three.
Where the seller does not live in Spain, the buyer is substitute taxpayer: you are on the hook for the payment even though the tax is economically the seller's. It is the second obligation buyers inherit without knowing, alongside the 3 % withholding on form 211. Both are worth settling in the deposit contract, in writing, long before the notary's office.
Inheritances, gifts and the cases people forget
The tax is not confined to sales. It arises on any transfer of urban land, which includes inheritances and lifetime gifts. On a gift it is the recipient who pays, and it is a cost that is regularly left out when families compare giving in life with leaving by will — occasionally it changes the answer. On an inheritance the deadline is six months from the death, with a further six available if you ask inside the first five months, and the reliefs for a main home passed to a spouse or children are often the difference between a large bill and almost none.
Your case, in two minutes
Your plusvalía: your map of obligations
The form for this service asks only what matters here. At the end you have your map of obligations, the deadlines running against you and a fixed price.
What your plusvalía costs
| Work | Price |
|---|---|
| Both calculations, the choice between them and the filing | 210 € |
| Each additional property in the same transaction | 104 € |
| From the third liable person onwards, each | 40 € |
| Refund claim where too much was paid | from 290 € |
| Appeal against a municipal assessment | Fixed quote |
Taxes included. With the two deeds and the latest IBI receipt we have enough to tell you what each method produces.
Our method with your plusvalía
We read the municipal by-law first, because the rate, the coefficients and the reliefs all come from it. We then run both calculations, show you the two figures before anything is filed, and file on the basis that produces the lower result. Where a town hall has already issued an assessment, we look at whether it compared the methods at all, and if it did not, that is usually the ground on which it is challenged.
What we need to work it out
Four documents settle almost every case. The deed by which you acquired the property, which gives the purchase price and the date. The deed of sale, gift or the inheritance documentation, which gives the transfer value and the date the tax falls due. The latest council rates bill, which carries the cadastral value and, crucially, the split between land and building. And the identification details of everyone liable, because each owner has their own share and their own bill.
Where the property was inherited, the value declared for inheritance tax replaces the purchase price, which is why those two files should never be handled in isolation from each other. And where works were carried out, keep the invoices: whether they can be added to the acquisition figure is argued, but they cannot be argued at all without documents.
The part that is decided before completion
In a sale between a resident seller and a resident buyer, this tax is the seller's and the timetable is straightforward. In every other configuration it is worth settling in writing in advance: who pays it, who files it, and what happens if the figure turns out to be larger than expected. A non-resident seller and a buyer who has not been told about the substitution rule is the combination that produces the complaints, and it is entirely preventable at the deposit contract stage.
Questions we are asked about your plusvalía
Is this the same as the capital gain on my income tax return? No. They are two different taxes on the same transaction: one municipal, on the land, and one national, on your gain. Both are payable and each has its own deadline.
I inherited five months ago. Am I in time? The deadline on death is six months, and a further six months can be requested inside that first period. Ask for it now: it costs nothing and it avoids a surcharge.
The town hall has assessed me. Can I argue? Yes. There is a one-month window for a request for reconsideration, and if the assessment used the objective method without comparing it with the real one, that is normally the ground.
I sold at a loss and they are still claiming. You answer with the two deeds. Where there is no increase in land value there is no taxable event and nothing to pay.
Is it payable on a gift from parents to children? Yes, and the recipient pays it. It belongs in the comparison alongside inheritance and gift tax.
