Municipal Plusvalía in 2026: How to Calculate and When It Is Exempt

# Municipal Plusvalía in 2026: How to Calculate and When It Is Exempt

The municipal plusvalía (Impuesto sobre el Incremento de Valor de los Terrenos de Naturaleza Urbana, IIVTNU) is one of the taxes that generates the most surprises when selling, inheriting, or donating an urban property. In 2026, the tax is mandatorily liquidated in the municipality where the property is located, and its amount can vary between a few hundred euros and several thousand euros depending on the cadastral value of the land and the years of ownership. The good news: there are legal exemptions that can reduce or completely eliminate the tax, and since the 2021 reform, you have the right to choose the most favorable calculation method.

What is the municipal plusvalía and who pays it

The IIVTNU taxes the increase in value that the urban land experiences from when the transferor acquired the property until it transfers it. It does not tax the value of the construction, only the value of the land. The taxpayer — who pays — varies depending on the type of transaction:

• Sale: the seller pays.
• Inheritance or donation: the heir or donee (who receives) pays.
• Dation in payment: in certain cases, it may fall on the financial institution.

The deadline to liquidate or self-liquidate the tax is 30 business days from the transfer in sales and donations, and 6 months, extendable to 1 year in inheritances (according to article 110 of the Real Decreto Legislativo 2/2004, Texto Refundido de la Ley Reguladora de las Haciendas Locales, TRLRHL).

The two calculation methods in 2026

After the Constitutional Court's October 2021 ruling and the Real Decreto-ley 26/2021 that reformed the IIVTNU, the taxpayer can choose the method that is most beneficial. The municipalities are obligated to accept the one you choose.

Objective method (coefficients on the cadastral value of the land)

A coefficient approved by the State is applied based on the number of years of ownership of the property, multiplied by the cadastral value of the land at the time of the transfer. The maximum coefficients are set annually by the Ministry of Finance through the Budget Law or equivalent norm; municipalities can apply coefficients equal or lower.

Formula:

Taxable base = Cadastral value of the land × Coefficient according to years of ownership

On this taxable base, the municipal tax rate is applied, which cannot exceed 30% (article 108 TRLRHL).

Real method (actual plusvalía obtained)

It is calculated as the difference between the sale price and the purchase price, applying the proportion that the land represents over the total value of the property according to the cadastral value.

Formula:

Real gain = (Sale price − Purchase price) × (% cadastral value of the land / total cadastral value of the property)

This method is especially useful when the property was bought a few years ago and the real appreciation is modest.

Practical example with the objective method

Imagine you sell an apartment in Madrid with a cadastral value of the land of 80,000 € and you have been the owner for 12 years. Suppose the municipality applies the maximum state coefficient for this range (check the current coefficients in the State Budget Law for 2026 or on your municipality's electronic portal).

If the applicable coefficient were, for illustration, 0.14 (indicative data; verify the exact coefficient in your municipality):

• Taxable base: 80,000 € × 0.14 = 11,200 €
• Municipal tax rate (example: 28%): 11,200 € × 0.28 = 3,136 € of tax

This amount may be reduced or eliminated if any of the exemptions we explain below apply.

Practical example with the real method

Suppose you bought that same apartment 5 years ago for 180,000 € and sell it for 200,000 €. The total cadastral value is 100,000 €, of which 60,000 € correspond to the land (60%).

• Real gain: 200,000 − 180,000 = 20,000 €
• Proportion of the land: 20,000 € × 60% = 12,000 € of taxable base
• Tax (rate 28%): 12,000 € × 0.28 = 3,360 €

In this case, the objective method would be more favorable if the coefficient for 5 years generated a base lower than 12,000 €. Always compare both methods before liquidating, as the savings can be significant.

When there is no plusvalía: exemption due to loss of value

Since the 2021 reform, if the land has not gained value between the purchase and sale, there is no taxable event and no municipal plusvalía is paid. To prove the non-existence of an increase, the taxpayer must provide the purchase and sale deeds before the municipality. If the transfer value is equal or lower than the purchase value, the liquidation is zero (article 104.5 TRLRHL, as amended by the RDL 26/2021).

This situation was especially relevant during the 2008-2013 real estate crisis, but it remains applicable in areas with stagnant markets or in operations with losses.

Legal exemptions of the municipal plusvalía in 2026

Beyond the absence of value increase, the law recognizes explicit exemptions. The most relevant ones are:

• Transfers for profit due to death in favor of the spouse, ascendants or descendants: municipalities can establish a bonus of up to 95% of the tax in inheritances (article 108.4 TRLRHL). It is not automatic: it depends on whether your municipality has approved it in its fiscal ordinance. Check your municipality's ordinance.
• Dation in payment of the habitual home: full exemption when the mortgage debtor delivers the habitual home to the bank to cancel the debt and does not have other sufficient assets (article 105.1.c TRLRHL).
• Transfers between spouses or in favor of children by court order of divorce or annulment of marriage: exempt according to article 105.1.b TRLRHL.
• Properties of public domain or affected to public utility purposes: exempt by their own nature.
• Physically disabled individuals: some municipalities approve additional bonuses in their ordinances. Check in your municipality.

The municipal plusvalía in inheritances: practical keys

In inheritances, the heir is the one who must liquidate the tax. The 6-month deadline (extendable to 1 year upon request) is counted from the date of the deceased's death. If the heir does not liquidate within the deadline, the municipality can initiate a verification procedure and impose surcharges and delay interest.

Key points to consider:

1. The cadastral value of the land taken is the current one at the time of the transfer (date of death), not the original acquisition value.
2. If the inherited property is sold later, the tenure period for a future plusvalía is computed from the date of acquisition by the deceased, not from the inheritance.
3. The 95% bonus in inheritances in favor of direct descendants does not exist in all municipalities: it is optional. Cities like Madrid or Barcelona apply it with specific conditions; check the local fiscal ordinance.

How to self-liquidate or declare the municipal plusvalía

The management of the tax corresponds to the municipality where the property is located, not the AEAT. The usual procedure is:

1. Access the municipality's electronic portal or present yourself at the municipal tax office.
2. Submit the transfer deed and, if you opt for the real method, also the acquisition deeds.
3. Complete the self-liquidation form or request that the municipality perform the liquidation.
4. Pay the resulting tax within the indicated deadline.

Some municipalities allow full electronic submission. Others require physical presence or postal notification. Check the specific procedure on your municipality's website.

Common errors to avoid

• Not comparing the two calculation methods: many taxpayers pay more because they liquidate using the objective method without checking if the real method is more favorable.
• Confusing the municipal plusvalía with the capital gain of IRPF: they are different taxes. The capital gain is taxed in the income tax declaration before the AEAT; the municipal plusvalía is paid to the municipality. Both can arise from the same transaction.
• Not requesting the bonus in inheritances: if your municipality has approved it, you must request it explicitly; it is not applied automatically.
• Missing the deadline in inheritances: the surcharge for late submission can reach up to 20% plus delay interest (article 27 General Tax Law).

Municipal plusvalía and habitual home: is there an exemption in IRPF?

It is important not to confuse two distinct figures. The exemption due to reinvestment in a habitual home that regulates IRPF (article 38 Law 35/2006 of IRPF) affects the capital gain declared in the income, not the municipal plusvalía. Selling the habitual home and reinvesting in another does not exempt you from paying the municipal plusvalía to the municipality. They are independent taxes with different regulations and managers.

Tools to calculate your plusvalía

Before liquidating, use the municipal plusvalía calculator available on your municipality's electronic portal (most large municipalities offer it for free). You can also use orientative calculators on specialized portals, although the final result is always determined by the competent municipality.

If you have doubts about which method suits you or if any exemption applies, consult a tax advisor or the tax service of your municipality before self-liquidating.
