If you strip everything back, there is one part of selling a Spanish property that consistently causes confusion for non-residents.
It is not finding a buyer. It is not the sale itself.
It is this: How does the 3% retention link to Capital Gains Tax, and what actually happens after completion?
If you are a non-resident selling property in Spain in 2026, you will pay a flat 19% Capital Gains Tax on your profit. To ensure this is paid, the Spanish Tax Authority requires the buyer to withhold 3% of your total sale price at completion (via a form called Modelo 211). You then have four months to file your final tax return (Modelo 210) to either pay the remaining balance or reclaim your overpayment.
Before diving into the percentages and forms, we need to clarify exactly what the Spanish Tax Authority is targeting.
Capital gains tax is applied strictly to the profit on your property.
Not the sale price. Not the amount you receive at completion. The gain.
Most sellers naturally focus on the final sale price. But the tax sits squarely on the difference between what you bought it for and what you sold it for, and that is where expectations often shift.
There is a major misconception that constantly alarms our British and American clients. Many believe they must pay 24% tax simply because they reside outside the EU.
While it is true that general non-resident income (such as rental yield) is taxed at 24% for non-EU citizens, the capital gains rate on a property transfer is entirely different.
The Capital Gains Tax on property in Spain for non-residents is fixed at 19% for everyone, regardless of whether you live in London, New York, or Berlin.

This is the part that almost every non-resident notices because it directly affects the funds you receive on the day of the sale. We see the same questions on almost every transaction:
“Why is 3% being taken?” “Is that the tax?” “Do I get it back?”
At completion, the buyer is legally obligated to withhold 3% of the agreed purchase price. They do not keep this money. They must pay it directly to the Spanish Tax Authority within one month using Modelo 211.
The reaction we see most often is, “So I have just paid 3% tax?”
Not exactly. The 3% retention is not your final Capital Gains Tax bill. It is a prepayment held by the government to ensure you settle your final liabilities before leaving the Spanish system.
"Many of our private clients panic when they see 3% of their sale price diverted at the notary.
Do not worry; this is standard procedure. If you are managing the sale from abroad, you do not even need to be in the room when this happens.
Our sister firm, PCC Legal, routinely acts as Power of Attorney for our clients, handling the retention and the subsequent reclaim completely on your behalf."
On paper, the calculation looks straightforward:
Sale Price minus Purchase Price minus Allowable Costs = Taxable Gain
In reality, the “Allowable Costs” are where sellers start asking questions. You can deduct several expenses to lower your taxable gain, including:
General maintenance, cosmetic upgrades, and replacement furniture cannot be deducted.
"This is where sellers lose thousands of Euros.
You can deduct the cost of major structural renovations to lower your tax bill, but the Spanish Tax Authority will only accept official VAT (IVA) invoices.
A handwritten receipt from a local builder will simply not be accepted. Always keep your official paperwork from day one."
Here is how the 19% tax and the 3% retention work together in a real world scenario.
In this example, the non-resident seller bought a property for €350,000, spent €40,000 on legal fees, taxes, and structural renovations, and is now selling it for €500,000.
Step | Description | Amount |
1 | Final Sale Price | €500,000 |
2 | Original Purchase Price | – €350,000 |
3 | Total Allowable Costs (Taxes, Notary, Renovations) | – €40,000 |
4 | Total Taxable Gain (Profit) | €110,000 |
5 | Capital Gains Tax Due (19% of the Gain) | €20,900 |
6 | 3% Retention (Withheld at Notary) | – €15,000 |
7 | Final Balance to Pay (Via Modelo 210) | €5,900 |
Note: If your total Capital Gains Tax (Step 5) was lower than the 3% retention (Step 6), the final balance would be the amount you reclaim from the Spanish Tax Authority.
Many non-residents sell their property, settle their 19% Capital Gains Tax, and assume they are finished.
They are then completely blindsided by a second bill.
This is the Plusvalía Municipal. It is a local town hall tax based strictly on the increase in the value of the land during the time you owned the property, regardless of what the bricks and mortar are worth.
Fortunately, the team at PCC Legal can calculate this for you in advance so there are no hidden shocks, and this payment can even be used as a deductible expense against your main Capital Gains Tax.
Completion feels like the end of the process. From a tax perspective, it isn’t.
Once the buyer submits your 3% retention, you have a four-month window from the date of the sale to file Modelo 210. This is your official tax return where your final position is actually determined.
There are two outcomes:
You must set realistic expectations regarding reclaims. The process requires a formal submission, and it typically takes between 6 to 12 months for a refund to hit your bank account. It does not change what you owe, but it does affect your cash flow after the sale.

A primary concern for our clients is paying tax twice.
Thanks to Double Taxation Agreements between Spain and countries like the UK and the USA, you are protected.
Generally, the tax you pay in Spain can be used as a foreign tax credit against your liabilities with HMRC or the IRS.
However, navigating cross-border tax requires meticulous planning.

No.
While Brexit changed the rules regarding rental income tax and residency, the Capital Gains Tax rate on property transfers remains at a flat 19% for UK citizens, exactly as it is for EU citizens.
If you sell your property for less than you bought it for (after calculating allowable costs), you do not owe Capital Gains Tax. However, the 3% retention will still be taken at the notary, and you must file Modelo 210 to claim your full refund.
The “reinvestment exemption“, which allows you to roll your profit into a new primary residence to avoid tax, is strictly for EU and EEA residents. Non-EU residents, including UK and US expats, cannot claim this specific exemption.
Once your legal representative files Modelo 210, processing times vary depending on the local tax office. In our experience on the Costa del Sol, it typically takes between 6 and 12 months for the Spanish Tax Authority to issue the refund.
Capital Gains Tax on property in Spain for non-residents is not complicated once you see the full sequence. The key to a stress-free sale is understanding that the 3% retention is the beginning of the tax process, not the conclusion.
At PCC Property, we believe you should never be surprised by the numbers on completion day.
