If you’re a British owner preparing to sell a property in Spain, there is a good chance your paperwork is not yet in order. In our experience advising British sellers, the overwhelming majority arrive at the point of sale missing at least one of four key documents or confirmations.
None of these gaps are fatal, but each one can slow down a sale, spook out a buyer’s lawyer, or reduce your profit expectations.
1. The Energy Performance Certificate (CEE)
As in the UK, to sell your house in Spain, you need a valid energy performance certificate.
The Spanish certificate must be obtained by a local qualified technical architect, who needs to visit and assess the property in person. The assessment itself does not usually take many days once it is booked, but it does require access to the property, and on overseas sales the owner is not always available, or easily reachable, to arrange that visit at short notice.
This is one of the most common sources of delay we see in cross-border sales, and it is entirely avoidable if you arrange the visit early rather than once you have a buyer waiting.
You must have it in place before advertising the property, as the energy rating must be shown in the property listings.
2. The Habitability Certificate or First Occupation Licence
This is the document that causes the most confusion among British sellers, and it is worth being precise about why. The underlying legal requirement, that a dwelling must meet certain minimum habitability conditions before it can lawfully be transferred or occupied, applies across the whole of Spain. What differs is not whether the law exists, but which specific document evidence compliance in each region, and how strictly it is enforced in practice.
Here is the point we think is most important for a seller to understand correctly, and where estate agents sometimes might give misleading comfort. In some areas, local practice has relaxed to the point where notaries or registrars do not routinely demand the certificate to complete a resale transaction, particularly for older properties where regularising the document would be burdensome. An estate agent may tell you, accurately, that “it is not asked for” in a given area. However, the fact that a notary or registrar does not insist on the certificate does not mean a buyer’s own lawyer will take the same relaxed view. It is entirely reasonable, and increasingly common, for a buyer’s legal representatives to request the habitability certificate or equivalent as part of their own due diligence, regardless of local administrative practice, precisely because it is the document that evidences the property meets minimum habitability standards, that there will be no unnecessary complications when changing the utilities onto the new owners and definitely something to have in place if the buyer is using a mortgage. Our advice is not to rely on the fact that it is not formally requested in your area. If you can obtain it, you should, because doing so demonstrates transparency to the buyer and removes a point of friction, or a renegotiation lever, later in the transaction.
3. IBI
IBI is something similar to the UK Council Tax, a recurring annual property tax. If you have owned your Spanish property for a while, you are probably already paying it by direct debit from your bank account each year, and it may feel like a formality you don’t need to think about until completion.
What genuinely matters to your bottom line is not simply the proof of payment, but the cadastral information contained on the actual council’s receipt: a breakdown between the land value and the construction value, which does not appear on your bank statements or direct debit confirmations. This information, along with the title deed, feeds directly into two separate calculations you will need to get right well before you accept an offer: your Spanish capital gains exposure on the sale, and the municipal tax on the increase in urban land value known as plusvalía municipal, both of which are typically calculated by reference to, or require as a starting input, the property’s official cadastral values.
4. The annual non resident tax filing you should have made every year
This is the area where we see the most misunderstandings, because it involves two separate, linked obligations that many non resident sellers are unaware of until the sale is already underway.
The obligation you should already have been meeting, every year you owned the property, is an annual non resident tax filing. Many British owners who have used their Spanish property purely as a holiday home, and have never rented it out, are unaware that they were still required to file this annual return declaring imputed income from the property, in addition to paying IBI. This is the filing obligation that should have been met every single year of ownership, well before any sale is contemplated. What happens if this obligation has not been met is linked to another tax, the capital gains tax on sale.
The 3% withholding sale is a different mechanism, and it is where an unfiled annual tax history causes real problems. When a non resident seller transfers a property in Spain, the buyer is legally obliged to withhold and pay to the Spanish tax authorities 3% of the agreed price, as a payment on account of the seller’s tax liability on the gain made since the property was bought and up to the point of sale.
This 3% is only ever a payment on account of the capital gains tax actually due on the sale, which is 19% of the gain.
If the 3% withheld exceeds the capital gains tax due, the seller is entitled to a refund of the difference.
If the tax due on your gain is higher than the 3% withheld, you will need to pay the balance.
You may have heard from an estate agent that you can simply claim the 3% back. In practice, that depends on two things: whether the tax due on your gain is less than the amount withheld, and whether your annual tax filings are up to date. If your filing history is incomplete, the Spanish tax authorities may delay the refund, or offset it against what you owe, until those years are regularised. Although the authorities can generally only look back for four years, discovering an unfiled history at this stage is an unwelcome, and entirely avoidable, surprise for a seller expecting a clean refund shortly after completion.
The Practical Takeaway
None of these four issues is a reason not to sell. But each is a reason not to wait until you have an accepted offer to find out where you stand.
If you are planning to sell a Spanish property and are not sure where your paperwork or your non resident tax filings stand, we can review your position, drawing on both Spanish and English law experience, and put a plan in place before you go to market.
