What Spanish form 211 is: the 3% the buyer withholds

The short answer

Form 211 is the self-assessment with which the buyer of a property situated in Spain pays in 3% of the price when the seller is a Non-Resident Income Tax payer without a permanent establishment³, and the Spanish tax agency publishes it under exactly that name⁸. It is not a tax on the purchase: article 25.2 of the consolidated act calls it, in so many words, a payment «as a payment on account of the corresponding tax» owed by the seller¹. The buyer has one month from the deed.

The buyer is the one liable, and that has consequences

The sentence in article 25.2 leaves no room: «the acquirer shall be obliged to withhold and pay in 3 per cent, or to make the corresponding payment on account, of the agreed consideration»¹. It is not an errand for the seller nor something the notary settles. The person liable is the one buying, and what answers for it if nothing is done is the property they have just bought.

That last part is literal. The same paragraph ends by saying that, if the withholding has not been paid in, «the transferred property shall answer for the payment» of the corresponding amount¹, and article 14.5 of the regulation supplies the mechanism: the land registrar «shall record this by a note in the margin of the relevant entry, stating the sum for which the property answers»². So the charge does not live in a file at the tax office but in the Land Registry, shows up on a nota simple, and stays there until it lapses or the receipt is produced.

The 3% is not the tax, and there is a point where they cross

This is the misunderstanding that moves the most money. The 3% is computed on the price. The seller's tax is computed on the gain, at the 19% set by letter f) of paragraph 1 of the same article 25¹. It is worth underlining that this letter, unlike letter a), draws no line between residents of the European Union and everyone else: 19% is the capital-gain rate for any non-resident, wherever they live.

Because they are two different bases, the two figures meet at exactly one point, and that point is arithmetic:

3% of the price = 19% of the gain, so gain = 3 ÷ 19 of the price = 15.7895% of the price.

Below that gain, the withholding overshoots and the seller is refunded. Above it, it falls short and the seller pays the difference. On 300,000 euros the point sits at 47,368 euros of gain: anyone who made less than that has a refund waiting, and anyone who made more has a payment pending. No further data is needed to know which side you are on.

The last row is the one that surprises people: selling at a loss does not remove the withholding, it removes the tax. Article 14.2 of the regulation admits only two exceptions and none of them is having lost money², so the 3% is withheld anyway and recovered in full.

Two clocks that chain

Article 14.3 of the regulation gives the buyer one month from the date of the transfer, and it must be filed «before the Delegation or Administration of the State Tax Administration Agency in whose territorial area the property is located»², not where the buyer lives.

Article 14.4 gives the seller three further months, and the wording matters: they run «from the end of the period established for paying in the withholding»². The two periods do not run together, they chain, so in practice the seller has four months from the deed.

A month runs date to date. Article 30.4 of Act 39/2015 says the period «shall end on the same day... in the month or year of expiry», and that «if the month of expiry has no day equivalent to the one on which the count begins, the period shall be deemed to expire on the last day of the month»⁷. So a deed of 16 March falls due on 16 April, and one of 31 January falls due on 28 February. And if that last day is a Saturday, Sunday or public holiday, paragraph 5 extends it to the next working day⁷.

The chaining only changes the answer at a month end, but it does change it: a deed of 31 March 2026 closes the buyer's month on 30 April, and three months from there is 30 July and not the 31st.

And the two rules should not be confused. What the seller chains to is the NATURAL end of the buyer's month, not the date the paragraph 5 extension may have moved it to. A deed of 31 January 2026 closes that month on 28 February, a Saturday, so the buyer has until Monday 2 March; the seller, by contrast, counts their three months from 28 February and falls due on 28 May. Both dates are right, and they do not start from the same day.

And form 210 is filed even when it is a refund

This is the sentence that changes the practical advice, and it is in article 5 of the Order itself. Self-assessments for income arising from property transfers are filed, says its letter a), «regardless of the result of the self-assessment», within that three-month period⁴.

Compare that with what the same Order lays down for every other refund on the same form 210: article 5.c).3 allows four years counted from the end of the period for declaring and paying in the withholding, and does not even allow filing before 1 February of the following year⁴. Same form, same tax, and two orders of magnitude of difference depending on the type of income. A seller who waits for «whenever it is due» is applying the wrong deadline.

Only two ways out, and neither is a treaty

Article 14.2 of the regulation lists exactly two cases in which the acquirer has no obligation to withhold²:

1. The transferor evidencing liability to Spanish personal or corporation tax by a certificate issued by the competent body of the tax administration. It is not enough for the seller to say so, nor to produce a foreign certificate of residence: the certificate is issued by the Spanish administration.
2. Contributing the property to the incorporation or capital increase of a company resident in Spanish territory. Article 25.2 excludes it from its own side in the same words.

A double-tax treaty is not on the list, and that is not an oversight: a gain arising from property situated in Spain is taxed in Spain under every treaty Spain has signed. And the seventh additional provision makes the same point from the opposite angle. A resident of the European Union or the European Economic Area can exclude the gain by reinvesting in a new main home, but its paragraph 3 says that «the withholding obligation laid down in paragraph 2 of article 25 shall also apply, as shall that of filing the return»⁵. The exemption does not stop the withholding. All the same paragraph allows is that, where the reinvestment has already taken place before form 210 falls due, it may be taken into account in determining the debt.

The property answers, but for the lesser of two amounts

Almost every page about this procedure cites the charge and stops there. The cap is in the same sentence. Both article 25.2 and article 14.5 of the regulation say, in identical words, that the property answers for the payment of «the lesser of that withholding or payment on account and the corresponding tax»¹².

That has two consequences worth understanding before signing:

• On a sale at a loss, the property answers for zero, however many thousands were never paid in. The corresponding tax is zero, and zero is the lesser of the two.
• On a sale with a large gain, the charge stops at the 3%. It does not climb to the whole tax: the withholding is the lesser of the two and it sets the ceiling.

A piece of paper the buyer has to hand over

The form consists of three copies, and the third is called «copy for the non-resident transferor»³. Article 8.4 of the Order says the acquirer, once the payment has been made, «shall hand a copy to the transferor, who will use it to evidence the payment on account when filing the self-assessment for the income arising from the transfer of the property»³.

It is an administrative detail with a large effect: the seller's refund depends on a document held by the buyer. It is worth asking for it at the notary's office or agreeing its delivery in writing, because once the deal closes the parties usually lose sight of each other.

The same purchase loads the buyer under three different acts

And two of them draw the line in different places, which produces the result fewest people expect.

Article 106.2 of the consolidated Local Finances Act makes the acquirer the «substitute taxpayer» where the taxpayer «is a natural person not resident in Spain»⁶. So buying from a non-resident company means withholding the 3% and not becoming the plusvalía substitute; buying from a non-resident individual means both at once.

And the bases do not coincide. The 3% is computed on «the agreed consideration», meaning the price alone, while the transfer tax on that same deed is computed on the greater of the Catastro reference value and the price. The two figures commonly differ, and both are correct: each is the base of its own tax.

A worked example with real numbers

A buyer acquires a flat on 16 March 2026 for 300,000 euros from a non-resident individual who had bought it for 250,000, with 3,000 euros of costs and taxes back then and 9,000 on this sale.

1. The withholding. 3% of 300,000 = 9,000 euros. The buyer hands 291,000 to the seller and files form 211 before 16 April 2026, at the tax office for the area where the property is.
2. The seller's actual tax. Acquisition value 250,000 + 3,000 = 253,000. Transfer value 300,000 − 9,000 = 291,000. Gain 38,000 euros, and at 19% the tax is 7,220.
3. The difference. 9,000 withheld against 7,220 of tax: the seller is refunded 1,780 euros, claimed on form 210 before 16 July 2026, four months after the deed, and filed even though it is a refund.
4. Had the buyer paid in nothing. The property would answer for 7,220 and not 9,000, because the law takes the lesser of the two.
5. And one more charge. Because the seller is a non-resident individual, that same buyer is the substitute taxpayer for the municipal plusvalía before the town hall.

The break-even gain on this deal was 47,368 euros. The actual gain was 38,000, below it, and that is why there was a refund: it was knowable before doing any arithmetic at all.
