Last legally reviewed: 25 September 2026. This guide concerns the Impuesto sobre el Incremento de Valor de los Terrenos de Naturaleza Urbana (IIVTNU), commonly called plusvalía municipal. It is a municipal tax on an increase in the value of urban land revealed by a transfer—not a tax on the whole sale price, nor the same return as Spain’s non-resident income tax. If you sell a flat, the land component matters; a transaction with no increase under the statutory test is not subject to IIVTNU.[1]
Who is liable if the seller lives abroad?
On a sale for consideration, the seller is the IIVTNU taxpayer.[1] When that seller is an individual not resident in Spain, the buyer is the statutory substitute taxpayer under Article 106(2) of the Local Treasury Law.[1] This is not an optional arrangement that only applies if the contract says so.[1] The provision is expressly framed around a non-resident natural person; do not extend that substitute rule automatically to a non-resident corporate seller.[1]
The parties should agree in writing how the cost will be settled between them and coordinate the town-hall submission. A private price adjustment is not itself a tax filing or proof of payment. Do not confuse this municipal substitute-taxpayer rule with the purchaser’s separate state-tax withholding on a non-resident property sale.[1][2]
What if the land did not rise in value?
Article 104(5) provides non-liability when the statutory comparison shows no increase in the land’s value.[1] It is not automatic merely because the owner made an overall loss or because the flat’s sale price was lower.[1] To claim it, declare the transfer and provide the acquisition and disposal deeds or other titles to the municipality.[1]
For each acquisition and disposal value, use the higher of the title value and any value assessed by the tax authority; do not subtract transaction expenses or taxes for this municipal comparison.[1] For a property combining land and building, apply the ratio of the land’s cadastral value to the total cadastral value at the tax accrual date to both the acquisition and disposal figures.[1] Inherited or gifted acquisitions need the statutory inheritance/gift-tax value rule.[1] Ask the relevant municipality what documents and route it requires; do not assume a zero-gain case needs no declaration.[1]
How is the taxable base calculated if there is an increase?
The standard or objective method uses the land’s cadastral value at the time of transfer, subject to applicable statutory and local adjustments, multiplied by the municipality’s coefficient for the generation period.[1] The base concerns at most 20 years of increase; the statutory table also addresses periods shorter than a year.[1] Municipalities approve their coefficients within the legal maxima, which can change, so an old article’s fixed coefficient range is not a safe current calculator.[1]
If, at the taxable person’s request and under the Article 104(5) comparison procedure, the actual statutory increase in the land value is lower than that objective base, Article 107(5) uses the lower increase as the taxable base.[1] This is a comparison of bases, not of the purchase/sale price difference with the calculated tax bill.[1] It does not allow blanket deductions for notary fees, IBI or other transaction costs in the IIVTNU land-value test.[1] The municipality sets the applicable tax rate, capped by statute at 30%; check its current ordinance for its rate, coefficients, reductions, bonifications and documentary requirements.[1]
A calculation illustration, not a quote
Suppose the verified land-value increase under Article 104(5) were €8,000 and the correctly computed objective base €12,000. On a duly supported request, €8,000 would be the Article 107(5) base; the local rate and any applicable lawful relief would then determine the tax. These are hypothetical inputs—not a TaxJoin client case or a prediction of your bill. If the statutory comparison instead shows no increase, the Article 104(5) non-liability route is different from choosing the lower base.[1]
When and where must it be reported?
For a sale between living persons, Article 110 sets 30 working days from accrual for the declaration to the relevant town hall; the tax accrues on the transfer date.[1] The ordinance determines the content of the declaration.[1] The municipality may choose a self-assessment system, in which payment of the resulting amount is due within the statutory period, or may issue a municipal assessment instead.[1] Do not describe every town hall’s process as self-assessment, and do not treat the notary’s notification to the town hall as a replacement for the parties’ own obligations.[1]
Before completion, identify the municipality where the land is situated and obtain its currently effective fiscal ordinance and official IIVTNU filing/payment instructions. Check its form, evidence, electronic-identification and representation requirements, any applicable local relief and how its working-day calendar is counted. This draft does not prescribe a nationwide “Form 600” for IIVTNU or promise that every municipality accepts an international transfer. Keep a dated filing and payment receipt.[1]
Is this the same as Form 210 or the buyer’s 3% withholding?
No. IIVTNU is handled through the municipality; Form 210 is the state non-resident income-tax return for the gain on a Spanish property disposal. AEAT states that the buyer, whether resident or not, generally withholds 3% of the agreed consideration and pays it using Form 211 within one month of transfer, giving the non-resident seller a copy. That withholding is credited against the seller’s eventual state-tax liability; an excess can be refundable.[2]
AEAT’s Form 210 instructions say a non-resident seller declares the property-transfer income and credits the buyer’s withholding.[3] For such disposals, Form 210 is submitted within three months after one month has elapsed from the transfer date, regardless of the return’s result.[3] This is a distinct clock from the municipal 30-working-day declaration.[1][3] A loss for Form 210 purposes does not by itself prove absence of an IIVTNU land-value increase under the different statutory calculation.[1][3]
Practical questions
Can the buyer pay the municipal tax and deduct it from my proceeds?
For a sale by a non-resident individual, the buyer is already the statutory IIVTNU substitute taxpayer, regardless of a clause. Document any commercial reimbursement or deduction from the agreed proceeds clearly, but do not present a contractual clause or a deduction on a completion statement as a substitute for declaring and settling the tax with the municipality. Separately identify any Form 211 withholding; it is not an IIVTNU payment.[1][2]
Can I submit or pay from outside Spain?
Consult the relevant town hall’s live electronic procedure and, if needed, ask how an authorised representative may file. Available identification, representation and payment channels are municipality-specific; this article does not promise remote submission or a particular transfer method.[1]
What if I missed the deadline or dispute an assessment?
Act promptly, preserve the deeds, cadastral breakdown, notifications and filing receipts, and obtain advice on the procedure and notice in that municipality. Do not rely on a universal surcharge timetable or a universal appeals forum from the old Spanish post; those claims are intentionally withheld pending a case-specific legal and procedural check.[1]
Next step
Prepare the purchase and sale titles, the cadastral land and total values at transfer, and the town hall’s current ordinance. Compare non-liability, the objective base and—where supported—the lower actual land-increase base before filing. Handle the separate Form 210 and purchaser’s Form 211 evidence on their own deadlines. If you need tailored help, ask TaxJoin to confirm the scope of its service before relying on it for municipal filing.[1][2][3]
