Plusvalía Municipal: The Tax Sellers Pay (and Buyers Should Check)

What is plusvalía municipal?

Plusvalía municipal is a local tax on the increase in the cadastral value of urban land when ownership changes. The Spanish name is the Impuesto sobre el Incremento de Valor de los Terrenos de Naturaleza Urbana, often shortened to IIVTNU. It is collected by the ayuntamiento where the property sits, separate from the Agencia Tributaria's capital gains tax on the profit from the sale. The tax follows the land, so a penthouse and a villa on the same plot share one land value in the cadastre, and a long hold in a town where cadastral values rose quickly produces a larger bill than a short hold where values were flat.

Who pays plusvalía when a property is sold?

The seller pays plusvalía by default. Contracts sometimes shift it to the buyer, which is legal if both parties agree in writing, but that is unusual on the Costa del Sol resale market and should never be accidental. Non-resident sellers still owe the town hall even when the buyer withholds 3% for state capital gains tax, because plusvalía is a municipal charge with its own form and deadline. The full state tax picture, including the 19% flat rate for non-residents and the 3% retention, is in our capital gains tax guide, and the step-by-step sale timeline is in our selling property in Spain guide.

How is plusvalía calculated after the 2021 reform?

Real Decreto-ley 26/2021 rewrote the base so sellers are not taxed on paper land gains that did not exist in the real sale. You now compare two figures and pay tax on the lower one, at a rate set by your town hall up to a legal maximum of 30%.

• Objective method: multiply the land's current cadastral value by a coefficient that depends on how many years you owned the land, then apply the municipal tax rate.
• Real method: take the actual gain on the land between purchase and sale, using the land's share of the total cadastral value to split the price, then apply the same municipal rate.
• If the real land gain is zero or negative, no plusvalía is charged, but you must still file the declaration so the town hall records the transfer.
• The plusvalía you pay as seller is deductible when calculating state capital gains tax, because it is a documented cost of the sale.

Since Real Decreto-ley 26/2021 the plusvalía base is the lower of an objective coefficient calculation or the real land gain, at a municipal rate legally capped at 30%, and transfers with no land gain are not taxedSource: Real Decreto-ley 26/2021, BOE · October 2026 · View market data →

Where do you find the land's cadastral value?

The land value is not the asking price on our listings and it is not the price on the escritura. It is the valor catastral del suelo on your IBI receipt, split from the value of the construction. If the receipt only shows a combined cadastral value, your gestor can pull the land split from the cadastre. That administrative value usually sits far below market medians on the Costa del Sol, which is why plusvalía bills often surprise sellers who priced their home against live asking data rather than the cadastre.

Costa del Sol active resale inventory: 7,858 listings, coast median asking €655,500 at €4,737/m²; Estepona median €614,500 across 888 listings and Marbella town median €850,000 across 441 listingsSource: Hometailor market data · October 2026 · View market data →

A worked example on a typical apartment hold

Take an apartment bought in 2014 where the land cadastral value was €80,000 and rose to €110,000 by 2026, with 12 full years of ownership. The ayuntamiento applies a 25% tax rate for this illustration. Under the objective method the base might be roughly €18,000 after the statutory coefficient on €110,000, producing tax of about €4,500. If the real land gain method gives only €6,000 because the overall sale price barely moved, the seller pays tax on €6,000 instead, about €1,500 at 25%. Your gestor runs both methods with the town hall's published coefficients before you accept an offer.

When must plusvalía be declared?

Every inter vivos transfer must be declared to the town hall within 30 working days of completion, whether tax is due or not. Missing the window triggers surcharges and interest set by local law. Most Costa del Sol ayuntamientos accept an online self-assessment with the nota simple and the deed reference, but the exact form name varies by municipality, so the gestor who handled your purchase is usually the fastest route again on the way out.

What should buyers check before they sign?

Buyers care because a seller who cannot pay an unexpected plusvalía bill can delay completion, and because some private contracts try to pass the tax across. Before arras, ask whether a recent cadastral revision landed during the seller's ownership, whether the land value on the IBI rose sharply, and whether the sale price is below the seller's purchase price so the real method may zero the tax. None of that replaces a gestor's calculation, but it surfaces the question early.

How plusvalía fits the rest of the exit bill

Plusvalía is one line in a stack that includes agency commission, notary costs, state capital gains tax and, for non-residents, the 3% retention. The ownership cost map, from purchase taxes through annual Modelo 210 filings, is in our guide to the costs of owning property in Spain. Planning the exit at purchase, with clean invoices and honest deeds, keeps every line predictable.
