What is municipal capital gains tax?

The municipal capital gains tax, officially known as the Tax on the Increase in the Value of Urban Land (IIVTNU), is a local tax levied on the increase in value of urban land when ownership is transferred.

It is important to understand that this tax is not levied on the value of the structures (buildings or homes), but solely on urban land. Local governments are responsible for collecting it, and the regulations may vary slightly from one municipality to another.

The legal basis for the municipal capital gains tax is found in the Local Finance Act (LRHL). Its purpose is to tax the profit a property owner realizes simply due to the passage of time, as it is assumed that urban land increases in value over the years.

Each local government has the authority to administer this tax, set the tax rate—which is generally between 29% and 30%—determine the applicable annual increase percentages, and establish tax credits or exemptions (for example, for primary residences in some cases).

Properties subject to the municipal capital gains tax include urban land (including building lots and land zoned for development), as well as homes, commercial premises, and garages, provided the land is classified as urban. However, this does not apply to rural land or land not zoned for development.

When does the obligation to pay it arise?

Taxable events

The municipal capital gains tax applies in certain situations, such as the sale of a property, when an urban property is transferred in exchange for a price. In this case, the tax is payable by the seller, although in practice it is often negotiated that the buyer assume this obligation.

It also applies in the case of a gift; if land or a home is given as a gift, the donee—that is, the person receiving the property—is responsible for the payment.

This also applies to inheritances, where heirs or legatees must pay the tax upon receiving property through inheritance, as well as to transfers for consideration, such as exchanges or awards in legal proceedings.

Some local governments grant exemptions in cases such as transfers to spouses or children involving primary residences, donations to nonprofit organizations, or inheritances of small estates (in some municipalities).

Taxpayers

Who is responsible for paying the tax is determined on a case-by-case basis. In the case of a sale, it is the seller, although it is sometimes agreed that the buyer will pay it. In the case of gifts, it is the donee (the person receiving the property). And in the case of inheritances, it is theheir or legatee.

For sales and donations, payment must be made within 30 business days of the transfer of ownership. For sales, the payment period is 6 months, and may be extended up to 1 year under certain conditions.

How is the municipal capital gains tax calculated?

Current methods for calculating municipal capital gains tax

The calculation may vary by municipality, but generally follows two methods. The objective method is based on the assessed value of the land and the time elapsed since the last transfer. On the other hand, the actual method may be applied if the actual increase in value is less than the calculated amount (following a claim).

Elements of Calculus

To calculate the amount of this tax, the following factors are taken into account: the assessed value of the land (excluding any structures), the number of years of ownership (with the assumption that the longer the ownership period, the greater the capital gain—up to a maximum of 20 years), and the tax rate, which is set by each local government and generally ranges from 29% to 30%.

Example of how to calculate municipal capital gains tax

Assuming that the assessed value of the land is €100,000, the period of ownership is 10 years, and the annual increase rate is 3.5% (which varies by municipality), the calculation would be:

  1. Total increase: 3.5% × 10 years = 35%
  2. Taxable income: €100,000 × 35% = €35,000
  3. Tax due: €35,000 × 30% (tax rate) = €10,500

How to Claim a Wrongfully Charged Capital Gains Tax: Step by Step

If you think you've overpaid, you can file a claim. This process, while it can be tedious, often allows you to recover significant amounts of money.

Who is eligible to file a claim?

A claim may be filed by the taxpayer who paid the tax, the affected heirs or donees, or their legal representatives (with a power of attorney).

Procedure and deadlines

An administrative claim may be filed within four years of the payment. A written claim must be submitted to the relevant city council, including supporting evidence such as an expert appraisal, valuation report, etc. If there is no response or if the response is negative, the matter may be taken to court by filing an administrative appeal within two months.

Required documents

You must submit proof of tax payment, the deed of sale, gift, or inheritance, an appraisal report (if using the actual cost method to demonstrate that there was no increase in value), and an up-to-date cadastral certificate.

You may file a claim if the property was sold for less than the purchase price, resulting in an actual loss; if the city government made an incorrect calculation (such as an error in the number of years of ownership or the assessed value); or if there was an applicable exemption that was not taken into account.

What happens if you don't pay?

Failure to pay the municipal property tax can result in serious consequences, such as penalties and surcharges. The surcharge is 5% if payment is made within three months of the due date, and 10% to 20% if the delay is longer. Late payment interest is calculated at the statutory rate.

Enforcement measures may be taken, such as the seizure of bank accounts or assets, inclusion on the list of delinquent debtors (RAI), or even enforcement proceedings by the city council.

Some city councils allow residents to negotiate payment plans (in installments) or offer discounts for early payment in some cases.

Tips for property owners, heirs, and donees

Check the assessed value of the land

You should request a cadastral certificate to ensure that the land value is correctly recorded. If the value is too high, you can request a review.

Use the actual cost method if there were losses

If the property was sold for less than the purchase price, you can use the actual cost method (rather than the target cost method) to reduce the taxable base. To do so, you will need an appraisal report demonstrating that no gain was realized.

Check exemptions and tax credits

Some local governments offer tax breaks ranging from 50% to 100% for primary residences, inheritances of small estates, and gifts to immediate family members.

Consult with an expert

An administrative manager or tax attorney can help optimize your tax calculation, file an appeal if there were errors, and negotiate payment terms with the city government.

Keep in mind the statute of limitations

The city council has four years to demand payment; if it is not notified within that period, payment may be avoided.
