How much tax do you pay when buying at auction?

Generally ITP, between 6 and 11 per cent depending on the region, or VAT if the transferor is a business. The tax authority may calculate it on the Cadastre reference value, not only on the winning bid.

Do you inherit the debts of a flat bought at auction?

Charges prior and senior to the one being enforced survive and are assumed by whoever wins the property. Later ones are usually cancelled. That is why you must review the Land Registry extract before bidding.

How much can the real cost exceed the winning bid?

It depends on the case, but between taxes, processing fees and possible charges, the real cost usually sits 10 to 15 per cent above the award price, and more if the property carries debt.

Costs, taxes and charges when buying at a judicial auction

What you really pay when buying a flat at auction: transfer tax or VAT, registry and notary fees, and the charges you inherit. With a worked example to estimate the real cost.

The winning bid is not the real cost

The most expensive mistake when entering an auction is confusing what you bid with what the property actually costs you. On top of the award price come taxes, processing fees and, above all, any charges the asset carries. Before deciding how much to bid, it pays to have the total estimated cost, not just the starting one.

Taxes: transfer tax or VAT

Buying a property at auction is generally taxed under the Transfer Tax (ITP), a tax ceded to the autonomous regions. The rate varies by where the property sits, usually between 6 and 11 per cent of the value. If the transferor is a business or professional and the deal is subject to VAT, that tax applies instead of ITP. The specific rule depends on the case, so confirm it before bidding.

Watch the taxable base

The tax authority may assess ITP on the Cadastre reference value, not only on what you paid. If you win well below that value, the tax can be calculated on a base higher than your award price. It is one of the costs that most surprises those who buy cheap.

Registry and notary fees

To register the property in your name you need the award decree and its entry in the Land Registry, which has a fee. Depending on the procedure, there may also be notary and agency fees if you delegate the paperwork. These are minor amounts next to the tax, but worth budgeting for.

Charges: what really decides the deal

A property at auction may carry prior registered charges: an earlier mortgage, attachments, homeowners' association debts or tax-related ones such as council tax. The general rule is that charges ranking after the one being enforced are cancelled on award, but prior and senior ones survive and are assumed by whoever wins the asset. If you bid without reviewing them, you can end up paying the award and, on top, a debt that was already on the property.

The source to check this is the Land Registry extract, which lists the registered charges and their rank. Cross-checking the auction information with that extract before bidding is the step that prevents the most losses.

Illustrative worked example

You win a flat for 80,000 euros in a region with 8 per cent ITP. If the tax authority assesses on the reference value, say 90,000 euros, the ITP would be 7,200 euros. Add around 600 euros of registry and agency fees and, say, 1,500 euros of association debt the flat carries. The real cost is around 89,300 euros, not the 80,000 of the bid. It is an illustrative example: every deal is different.

How to estimate the total cost before bidding

Request the registry extract and locate the prior charges and their rank.
Calculate the tax (ITP or VAT) on the correct base, not only on your price.
Add registry, notary and agency fees.
Add debts the property inherits, such as association fees or unpaid council tax.
Compare that total cost with your real valuation of the property today.
