Rental year 2026: we are getting it ready now. The Form 210 for rent received in 2026 is filed from 1 to 20 April 2027 (to 15 April if you pay by direct debit): since the 2026 tax year it is no longer January, which is what Order HAC/623/2026 changed. What takes the time is not the form, it is the paperwork behind it: platform statements, contracts, cost invoices and your certificate of residence. We collect it over the winter and file on the first day the window opens.
Selling a flat in Spain when you are not tax resident here is not one transaction but three: the signing, the 3 % the buyer withholds and pays in, and your own return, which comes months later. Each has its deadline and its form, and the three are chained together: if the second goes wrong, the third gets complicated. This guide walks through the whole timetable and warns you about what tends to surface from the past once the rug of the escritura, the notarial deed of sale, is lifted.
The timetable at a glance
| Moment | Who acts | What they do |
|---|---|---|
| Before signing | Seller | Gathers the purchase deed, costs, the certificate of debts to the comunidad de propietarios (the owners' association), the latest IBI property tax bill and the certificate of tax residence |
| Day of signing | Buyer | Withholds 3 % of the price and gives the seller proof that it will be paid in |
| One month from signing | Buyer | Pays the 3 % in on Modelo 211 |
| Three months more | Seller | Files their Modelo 210 declaring the gain and subtracting the 3 % already paid in |
| In parallel | Depends on the case | The municipal plusvalía tax at the town hall |
Four months from signing to the seller's 210: one month for the buyer and three for you from the end of that first month. It is a comfortable deadline if you start in time, and a very short one if you find out in the third month that half the paperwork for a purchase twenty years ago is missing.
Step 1: the 3 % the buyer withholds
Article 25.2 of the consolidated text of the Non-Resident Income Tax Act (the TRLIRNR, which governs the IRNR) requires the buyer to withhold and pay in 3 % of the agreed price when the seller is a non-resident without a permanent establishment. It is not a tax: it is a payment on account of the seller's tax.
- The buyer does it, and is liable if they do not: the property remains charged with payment of the debt.
- It is paid in on Modelo 211 within one month of the sale.
- The seller needs the copy of the 211 to subtract it on their 210. Without that paper, the deduction cannot be claimed easily.
It is the document most often lost in these transactions. The buyer already has their home and the seller is in another country: chasing it from abroad, with the 210 deadline running, is awkward. The sensible course is to provide in the arras contract (the deposit agreement signed before completion) how and when the copy will be handed over, and to check the payment before the deadline expires. We develop this in how to provide for it before signing, and the mechanics of the form in how Modelo 211 is filled in.
Step 2: the gain, which is hardly ever what you think
The gain is calculated under the rules of Spanish personal income tax (the IRPF): transfer value minus acquisition value. The transfer value is the price less the expenses and taxes inherent in the sale borne by the seller. The acquisition value is the price paid at the time plus the costs and taxes of that purchase, plus improvements, and minus depreciation if the property was let.
| Item | Adds or subtracts |
|---|---|
| Sale price | Starting point |
| Agency commission, municipal plusvalía paid by the seller, certificates | Subtracted from the transfer value |
| Purchase price | Base of the acquisition value |
| ITP transfer tax or non-deductible VAT, notary, registry and gestoría on the purchase | Added |
| Documented improvement works | Added; repairs are not |
| Depreciation for the years of letting | Subtracted, and the minimum is counted even if it was not deducted |
The two items that cause the most arguments have their own guides: improvement or repair and the depreciation that is subtracted even if you never deducted it. The full calculation, with examples, is in how the gain is really calculated.
Step 3: your Modelo 210
The capital gain of a non-resident without a permanent establishment is declared on Modelo 210, at the rate set by article 25 of the consolidated text (currently 19 % for gains from the sale of assets) and subtracting the 3 % already paid in by the buyer. Three possible results follow.
| Result | What it means | What has to be done |
|---|---|---|
| Payable | The 3 % fell short of the tax due | Pay the difference on time |
| Refundable | The 3 % exceeded the tax due, or there was a loss | Claim the refund, giving a bank account. It is the most common result in sales with a small gain |
| Zero | No gain and no withholding to recover | Declare it anyway |
A refund is the typical case of someone who bought at a high price and sold without much of a gain: the 3 % is calculated on the price, not on the gain, so it can comfortably exceed the tax owed. How it is claimed and how long it takes is in how to recover the 3 % withheld, and the full timetable, with its nuances, in the complete timetable of a sale.
If the flat belongs to a married couple, there is no joint return: there are two Modelo 210s, one for each owner and for their percentage, each with their share of the 3 %. The same happens with the 211: the buyer must break the withholding down for each non-resident seller. Filing a single form for the total is a mistake that means redoing the whole thing.
The municipal plusvalía, and who pays it
The tax on the increase in value of urban land (the plusvalía municipal) is, by law, the seller's. But when the seller is a non-resident, the local finance legislation makes the buyer a substitute for the taxpayer: the buyer is the one liable to the town hall, although they may pass the cost on to the seller. It is worth making this clear in the contract, because in practice it is deducted from the price, sometimes by an estimated amount that then turns out not to match.
The two methods of calculation and the cases in which nothing has to be paid are in the two methods, compared with an example and when there is no increase in value. It is a figure that can move several thousand euros and that is almost never calculated before signing.
What surfaces from the past
This is the part nobody expects. A sale opens the door to a review of earlier years, because the tax authorities suddenly see how long you have owned the property and what you have declared in that time.
| Previous situation | What the obligation was | What to do |
|---|---|---|
| The flat stood empty or at your disposal | Annual Modelo 210 for imputed income from property | Review the years not yet time-barred: see imputed income |
| The flat was let | Modelo 210 for the rental income, at the frequency that applies | See the rental Modelo 210 and check what is missing |
| Nothing was ever declared | Both, depending on the use | Put it right before the sale, not afterwards |
The order matters a great deal: correcting voluntarily, before any request, falls within the surcharge regime; doing it after the letter arrives falls within the penalty regime. The difference is explained in surcharge, interest and penalty, and how far back it goes in the four-year limitation period.
Two situations with their own rule
- Residents of the European Union, Iceland, Norway or Liechtenstein selling what was their main home in Spain. The seventh additional provision of the consolidated text allows the gain to be taken out of tax when it is reinvested in another main home, by reference to the IRPF conditions. It is a real and little-known route, and its conditions are the ones we explain in the four conditions.
- People over 65. The IRPF exemption on the sale of a main home is designed for taxpayers of that tax and does not simply carry over to non-resident income tax. It is a point to be analysed case by case, and we are not going to state here that it applies, because it depends on the particular situation.
The certificate of tax residence
It is the document that holds everything else up: it shows the Spanish tax authorities that you are tax resident in another state and, when it is issued for treaty purposes, allows the double tax treaty's rules to be applied. It is valid for a limited time and it is worth requesting in advance, because some foreign tax administrations take weeks. The two kinds of certificate and what each one is for are in the ordinary certificate and the treaty certificate.
The checklist for the week before signing
- Purchase deed and invoices for the costs at the time.
- Evidence of the improvement works, with invoice and bank payment.
- History of lettings and of the 210s filed, if there were any.
- A current certificate of tax residence.
- A written agreement with the buyer about the 211 and about the municipal plusvalía.
- A bank account for any refund, with its ownership clear.
We are tax lawyers and we handle non-resident sales from start to finish: the calculation beforehand, the 210, checking that the 211 was paid in, and correcting whatever comes up from the past if needed. We do not guarantee the outcome of a review or how long the tax authorities take to refund, because that is not in our hands. Tell us about the transaction in the non-resident form, or first read the page on non-resident property tax and the one on having sold a property.
