Valor de Referencia Spain

How much tax does the Valor de Referencia cost you?

The property transfer tax (Impuesto sobre Transmisiones Patrimoniales, ITP for short) in Spain isn't calculated on the price you actually pay, but on the higher of two values: the notarised purchase price and the Valor de Referencia, the cadastral reference value. If the reference value is higher, you end up paying tax on money that never changed hands. In the Balearic Islands, the rate starts at 8% and reaches 13% at the top bracket — so the gap between the two values can add a double-digit percentage to your bill. The calculator above shows you both amounts for your case and the difference between them.

Anyone who nonetheless declares only the purchase price risks more than just a back payment: the fine for the minor offence is 50% of the unpaid tax. Anyone who corrects the mistake themselves, on the other hand, only pays a late-payment surcharge — and no fine.

How it's calculated

For decades, the agreed purchase price was the basis. Anyone who notarised a lower price saved on tax; the authority was allowed to apply a higher value, but had to justify and prove it on a case-by-case basis. With Ley 11/2021, the legislator reversed this burden of proof: the cadastral office now sets the reference value in advance and publicly, it applies as given, and anyone who considers it too high must now prove that themselves. Anyone who buys a property in Mallorca is therefore no longer dealing with a retrospective estimate, but with a figure that is fixed in advance — and that can be looked up beforehand.

The rule is set out in Article 10, paragraph 2 of the Spanish property transfer tax law (Texto Refundido, Real Decreto Legislativo 1/1993), as amended by Ley 11/2021. It is short:

For real estate, the value is the Valor de Referencia set by the cadastre on the date the tax arises. However, if the value declared by the parties, the agreed price, or both, is higher than the reference value, the higher of these values applies as the tax base.

From this, the whole calculation follows in three steps:

1. Determine the tax base. The higher of the purchase price and the reference value. If both are equal, there is no higher one — the purchase price stands.
2. Apply the rate. The progressive Balearic scale is applied to the tax base. It works like an income tax table: each bracket is taxed at its own rate, not the whole amount at the top rate. You'll find the full scale and all the reductions in the calculator for property transfer tax (ITP) in Mallorca.
3. Work out the difference. The tax on the tax base minus the tax on the purchase price. That's the amount the reference value costs you.

The expensive special case: the reference value can wipe out a tax reduction

This is where most calculations fall short — and why a simple rate difference is misleading. The Balearic tax reductions (the reduced rate for a main home, the rate for under-36s, the full exemption for under-30s) are all tied to a value threshold per island.This limit is measured against the tax base, not against the purchase price.

This follows from the underlying logic: the law and the Balearic tax authority speak of a limit for the value of the property, and what counts as the value is precisely defined by Article 10 cited above — the higher of the reference value and the purchase price. There is no official worked example so far in which the two values diverge; the published examples from the ATIB (Agència Tributària de les Illes Balears, the Balearic tax authority) deal with cases in which the declared value and the tax base match. If your case hinges on this limit, that's the point at which getting advice pays off.

If your purchase price sits just below the limit and the reference value just above it, you lose the tax relief entirely. What was a surcharge of a few percent on a few thousand euros then becomes a five-figure sum. Set up a buyer profile with tax relief in the calculator above and push the reference value above the limit — the calculator will tell you which limit was crossed and what it costs.

Three cases that show the difference

Below the calculator are three worked-through cases. They aren't hard-coded but are recalculated from the registered tax rates every time the page loads — so they can't go out of date, even while the text stays the same.

• The standard case. Purchase price below the reference value, no tax relief. Here the reference value costs exactly the rate difference on the excess amount: unpleasant, but manageable.
• The expensive case. A young buyer on Menorca, whose purchase price is below the value limit and whose reference value is above it. The tax relief is lost, and the additional tax is a multiple of the rate difference.
• The harmless case. The purchase price is above the reference value. In this case, the reference value changes nothing — and on Mallorca, in good locations, this is the more frequent outcome, because market prices there exceed the cadastral values.

Valor de Referencia and Valor Catastral: two figures, two purposes

Many buyers confuse the two. That's understandable, since both come from the land registry (Dirección General del Catastro, or Catastro for short — the Spanish authority that records and assesses land and buildings). However, they serve different purposes.

For your ongoing property tax, the Valor Catastral therefore remains decisive. For the purchase, inheritance or gifting of a property, the Valor de Referencia has applied since 2022.

Where to look up the reference value

The official point of reference is the online portal of the Spanish land registry authority. For this you need the Referencia Catastral — the twenty-digit reference number under which the property is registered in the Catastro. You can find it:

1. in the estate agent's listing or purchase offer,
2. in the seller's current IBI notice,
3. on the land registry extract (Nota Simple),
4. on major property portals, often directly on the listing.

How to obtain the number and what else the Catastro extract reveals is explained in the guide on the Catastro in Spain. The reference value is reassessed annually: if several months and a change of year lie between reservation and notarisation, it's worth taking a second look shortly before the notary appointment.

Special cases

There is no reference value for the property

Not every property has a certified reference value. Typical examples are newly built buildings not yet fully recorded in the Catastro, undeveloped plots in remote locations, and properties with unclear cadastral records following an unreported renovation.

In that case, not automatically the purchase price. Article 10 paragraph 2 explicitly names, for this case, the highest value out of declared value, agreed price and market value — and the authority may still determine the market value itself. The difference to the reference value is practical in nature: you only find out the figure after the purchase, not beforehand.

New build from the developer: no issue at first, then it is one

When purchasing a newly built property directly from the developer, no property transfer tax is due, but instead VAT (IVA) applies. Its assessment basis is the agreed price; the reference value plays no role for IVAno role.

For the stamp duty (Actos Jurídicos Documentados, AJD for short), which additionally applies when buying a new build, this does not hold, however. Article 30 paragraph 1 of the Property Transfer Tax Act explicitly stipulates that the value of a property may not be set lower there either than under Article 10 — meaning not below the reference value. Anyone calculating a new-build purchase in Mallorca should factor this in; and upon a later resale, the reference value is once again the decisive figure anyway.

Inheritance and gift

For inheritances and gifts of property too, the reference value applies as the minimum value of the assessment basis, provided it exceeds the declared value. This becomes especially noticeable when parents transfer a property to their children at a symbolic price: the tax is calculated on at least the reference value, regardless of what the contract states. Allowances and rates for the Balearics can be found in the guide on inheritance and gift tax in the Balearics.

Upon sale

For the seller, the reference value is relevant in two respects. The municipal capital gains tax (Plusvalía Municipal) continues to be derived from the Valor Catastral, not from the reference value. Regarding the capital gain for income tax purposes, however, it is disputed whether a higher reference value applied at purchase also counts as the acquisition value and thereby reduces the later gain. This question has not been conclusively resolved — seek individual advice on this. The overview can be found in the guide on taxes when selling property in Spain.

The reference value is too high — what then?

The law stipulates that the reference value may not exceed market prices. In locations with a thin data basis or strongly fluctuating prices, this nevertheless occurs. The Constitutional Court unanimously declared the system constitutional in February 2026, while explicitly leaving open that the value can be challenged in individual cases with any admissible means of evidence.

The path taken matters: Article 10 paragraph 3 only allows the reference value to be challenged in two constellations — via an appeal against the tax assessment (liquidación) or via an application to correct one's own self-assessment (autoliquidación). It doesn't work as a precaution, without a concrete tax case. In both cases, the tax administration obtains a binding opinion from the Land Registry Office.

In practice, this means: pay first, dispute afterwards. Anyone who transfers less to apply pressure produces a back payment plus surcharge instead of a clean legal remedy. Proof is usually provided by a counter-appraisal from a licensed expert — more on this in the guide to Tasación, property valuation in Spain.

Deadlines and forms

The property transfer tax is self-calculated and self-declared. The responsible authority in the Balearics is the ATIB, and the form is the Modelo 600.

• One month from the day of notarisation to declare and pay. Not thirty working days, and normally no extension of the deadline.
• If you notice the mistake later, you submit a supplementary self-assessment (declaración complementaria). The surcharge is 1% plus the same rate for each additional full month, capped at twelve months; after that it is 15% plus default interest. Within the first twelve months, no interest accrues.
• The decisive advantage of voluntary disclosure: Anyone who corrects it themselves under this rule commits no administrative offence. The fine is waived entirely, not just partially.
• If the authority reports first, it's too late by then. It then sets the difference by official notice, and the fine is added on top. It can be reduced if you agree to the additional assessment and pay on time without appeal — the calculator above works out both reductions.
• The authority has four years. The limitation period runs from the end of the declaration deadline. A purchase from last year is therefore not a closed matter. The ten-year period one occasionally reads about concerns loss and deduction carryforwards and plays no role in property purchases.

The most common mistakes

1. No check before the notary appointment. Many buyers only find out from the official notice that the reference value was above the purchase price. The lookup takes less than ten minutes and only needs the Referencia Catastral.
2. The value threshold measured against the purchase price. Anyone claiming a benefit is checking the threshold against the wrong value — it applies to the tax base. This is the most expensive individual mistake on this page.
3. Purchase price "bid up" to the reference value. That doesn't help: for tax purposes, the higher value counts anyway. It only increases the price you actually pay.
4. Appeal missed. The legal remedy against the assessment notice has a deadline. Anyone who lets it lapse loses the route — and indeed the only one that Article 10 paragraph 3 opens up at all.
5. Confusion with the cadastral value. The figure on the IBI assessment notice is not the reference value.
6. Gift without review. Family transfers are often carried out without a prior tax review. If the reference value is significantly above the value applied, it becomes expensive.

Checklist before notarisation

• Referencia Catastral obtained (listing, Nota Simple or IBI assessment notice)
• Valor de Referencia checked and compared with the purchase price
• Checked whether a certified reference value exists at all
• Tax calculated on the higher value, not on the purchase price
• In the case of reductions: value threshold checked against the assessment basis reviewed
• If the reference value seems clearly too high: counter-appraisal obtained
• one-month deadline for the Modelo 600 noted in the calendar

In brief

The reference value has been the reality of property purchases in Spain since 2022, and the logic is simple: the purchase price and the reference value are compared, and the higher one determines the tax. In Mallorca, market prices in good locations are often above the cadastral values — in that case, the reference value changes nothing. Where it is higher, it costs you, and where it tips a reduction, it costs a lot.

The good news: you find out beforehand. A lookup using the Referencia Catastral takes minutes, and the calculator above tells you what the difference means for your case. If the reference value turns out unreasonably high, there is an orderly way to challenge it — via the tax assessment, not by simply paying less.
