Yes: within certain limits, your home can be liable for tax debts run up by the previous owner, even though you had nothing to do with them. The mechanism is called tax affection, and it means certain taxes are secured against the property itself, so the debt travels with the house rather than only with the person. The good news is that the risk is limited, it can be checked before you sign, and three or four documents will neutralise it.
What exactly is tax affection?
It is a legal guarantee the tax authorities hold over the asset. When a sale or an inheritance leaves taxes that were not correctly settled, the property becomes liable for that debt. In practice this takes the form of an entry in the Land Registry, the so-called marginal affection note, which warns any future buyer that the guarantee exists.
The most common case is not a defaulting seller but a valuation issue: if the tax office considers the property was declared below its reference value, it issues a supplementary transfer tax assessment. If that assessment goes unpaid, the property is liable.
Which debts follow the property and which do not?
This is the table worth having in front of you before signing, because not every seller debt is inherited:
| Item | Follows the property? | Limit or term |
|---|---|---|
| Council tax (IBI) and municipal charges | Yes, the property is liable | Non-time-barred years, generally four |
| Supplementary transfer or inheritance tax | Yes, via an affection note | The note lapses after five years |
| Community of owners fees | Yes, the flat is liable | Current year plus the three previous ones |
| Seller's mortgage | Yes, unless cancelled at the Registry | Until the registry entry is cancelled |
| Municipal capital gains tax | Paid by the seller, with one exception | If the seller is non-resident, the buyer is liable |
| Electricity, water, internet | No, these are personal debts of the account holder | No effect on the property |
| Fines and other seller debts | No | Unless already registered as a seizure |
Two rows deserve special attention. The community one, because the amount can be substantial if there was a special levy nobody paid. And municipal capital gains tax: when the seller is not resident in Spain, the law makes the buyer responsible for paying it, something particularly common on the Costa del Sol.
How long does the risk last?
The affection note is valid for five years from its date; once that period passes it lapses and no longer secures anything. As a general rule, moreover, tax debts become time-barred after four years, a period that restarts each time the authorities take a step formally notified to the taxpayer.
In practice this means the real risk is concentrated in the first years after the previous sale. If the home you are looking at changed hands eight years ago and the marginal note has already lapsed, that front is closed.
Can they seize your home overnight?
No. Before anyone touches the property there has to be a procedure with formal notification of the debt, a voluntary payment window and an enforcement stage. Seizure is the last link in the chain, not the first, and at every stage there is scope to make representations, pay or appeal.
It is also worth knowing that if you end up paying a debt that belonged to the seller, you retain the right to claim it back from them. It is a dispute you would rather avoid, but the money is not lost by definition.
What should you check before signing?
- A Land Registry extract updated to the day of signing: this is where mortgages, seizures and any live affection notes appear.
- The latest paid council tax receipts and a certificate from the town hall confirming municipal taxes are up to date.
- A certificate from the property administrator confirming fees are up to date and listing any approved but unpaid special levies.
- The cadastral reference and the property's reference value, to anticipate whether the declared price might trigger a supplementary assessment.
- If the seller is non-resident, plan for the 3% retention of the price that the buyer must pay to the tax office on account of the seller's tax.
All of these documents are requested before signing, not after, and their cost is trivial compared with that of an unpleasant surprise. The notary checks the registry position at the moment of the deed, but does not vet community or municipal debts: that is the buyer's job, and their advisor's.
Does anything change if you buy on the Costa del Sol?
What changes is the relative weight of two risks. The first is municipal capital gains tax with a non-resident seller, which here is an everyday scenario: in Marbella, Estepona, Mijas or Benahavís a significant share of sellers are tax-resident outside Spain, and in that case the buyer becomes the party liable to the town hall.
The second is the supplementary transfer tax assessment. In Andalusia the general transfer tax rate is 7%, so a €50,000 valuation gap on the declared price translates into roughly €3,500 in additional tax, plus interest. Comparing the price with the reference value before signing the deed stops being a technicality and becomes a budget item.
Conclusion
Tax affection frightens people more through unfamiliarity than through its actual reach. It is not a hidden trap: it is recorded at the Registry, it has an expiry date, it is limited to specific taxes and it requires a procedure with formal warnings before anything serious happens. A well-prepared purchase, with a same-day registry extract, municipal and community certificates and a look at the reference value, reduces the risk to virtually nil.

Frequently asked questions
Can the tax office claim unpaid council tax from the previous owner?
Yes. Council tax is a debt secured against the property itself, so the town hall can pursue the home for any years not yet time-barred, generally the last four. That is why you should ask the seller for paid receipts and a municipal certificate confirming payments are up to date.
How many years of community fees does the buyer take on?
The current year plus the three previous calendar years, under the Horizontal Property Act. This is why you should never sign without the administrator's certificate, which must also disclose any approved and unpaid special levies.
What is the marginal affection note at the Land Registry?
It is the entry warning that the property is liable for a tax arising from the transfer, usually transfer or inheritance tax. It appears on the registry extract, shows the date and lapses after five years. If you see a live one, clarify its origin before signing.
Who pays municipal capital gains tax if the seller lives outside Spain?
The buyer, whom the law designates as substitute taxpayer when the seller is not resident in Spain. The buyer can later reclaim the amount from the seller, but as far as the town hall is concerned the buyer is liable. On the Costa del Sol this is a very common situation and should be dealt with in the contract.
What is the 3% retention when buying from a non-resident?
When the seller is not tax-resident in Spain, the buyer must withhold 3% of the price and pay it to the tax office on account of the seller's tax. It is not an extra cost for the buyer, but a portion of the price paid to the authorities instead of to the seller.
