Aisha bought a flat in Benalmádena on 15 December 2025 for €195,000 from a seller who lives in Utrecht. At the notary's office she handed a provisión de fondos, a payment on account for costs, to the estate agency's gestoría (the administrative agency that files forms for clients) so that it would file Modelo 211. The gestoría filed it on time, but it calculated the 3 % on the cadastral value, €120,000, instead of the price: it paid in €3,600 when €5,850 was due. €2,250 is missing. Aisha found out in September 2026, when the seller's adviser asked her for an explanation. Before Hacienda, the tax authorities, the person liable is her. Before the gestoría, she has a contract and a payment on account to explain.
Before Hacienda, the withholder is whoever buys
Article 25.2 of the Non-Residents Income Tax Act places the obligation to withhold and pay in the 3 % on the acquirer. Not on the notary, nor on the estate agency, nor on the gestoría that fills in the form. Entrusting the procedure to a professional is perfectly normal and the reasonable thing to do, but it does not transfer the obligation: if Modelo 211 goes wrong, the Agencia Tributaria, the Spanish tax agency, turns to Aisha. What Aisha has against the gestoría is a contractual relationship, and that is argued in the civil courts, not in the tax file. The full framework of the form is on the page on Modelo 211.
Typical mistakes in a Modelo 211 and where they show up
| Mistake | When it is noticed | How it is corrected |
|---|---|---|
| Wrong base: cadastral or reference value instead of the price | When the seller files his Modelo 210 and the figures do not match | A supplementary Modelo 211 for the difference, with a surcharge if the deadline has passed |
| Withholding on the whole price when only one co-owner was non-resident | When the resident co-owner claims what was deducted | An application to rectify Modelo 211 and a refund of the excess paid in |
| Modelo 211 filed outside the month | When the surcharge assessment is notified | Pay the surcharge; what is open to argument is who bears it |
| Seller's copy not handed over | When the seller cannot ask for his refund | Find the receipt and send it |
| Seller's NIE or details entered wrongly | When the tax authorities cannot match Modelo 211 with the seller's Modelo 210 | Rectification of the identifying details |
Correcting Aisha's case, with numbers
- Correct withholding: 195,000 × 3 % = €5,850.
- Paid in by the gestoría: 120,000 × 3 % = €3,600.
- Difference: €2,250, paid in with a supplementary Modelo 211 identifying the same transaction and the same period.
- Delay: the deadline ended on 15 January 2026. Filing on 30 September, eight full months have elapsed, from 16 January to 15 September.
- Article 27 surcharge (the recargo for filing late unprompted): 1 % + 8 points = 9 % on the difference: 2,250 × 9 % = €202.50.
- With the 25 % reduction for paying the surcharge assessment within its period: €151.88.
Because she puts it right herself before any request from the tax office, there is no penalty. If she waited for Hacienda to match her Modelo 211 against the seller's Modelo 210, the story would be different: there would no longer be a surcharge, and the unpaid part of a withholding never gives rise to a minor infringement. We explain it in surcharge versus penalty.
Where the missing €2,250 is
This is the question almost nobody asks. If Aisha deducted the €5,850 from the price and gave it to the gestoría as a payment on account, and the gestoría only paid in €3,600, the difference has not evaporated: it is in the gestoría's account, in Aisha's or, if the calculation was wrong from the escritura (the deed of sale) onwards, in the seller's. Before talking about damages, the path of the money has to be rebuilt with the supporting documents:
- Escritura: how much was paid to the seller and how much was withheld.
- Receipt for the payment on account: how much the gestoría received and for what.
- Modelo 211 receipt with its NRC, the bank's payment reference: how much reached the Treasury.
- The gestoría's final statement: whether it returned any surplus.
If the gestoría holds the difference, the first step is not a claim for damages: it is the return of a payment on account not applied to its purpose.
What can be claimed from the gestoría and what cannot
| Item | Is it recoverable damage? | Why |
|---|---|---|
| The €2,250 of withholding | Not as damage | Aisha had to pay it in anyway. If the gestoría holds it, it is claimed as a payment on account not applied |
| Surcharge of €202.50 or €151.88 | Yes, in principle | It would not exist without the calculation error |
| Fees for filing the supplementary return | Yes, in principle | It is the cost of undoing the error |
| A penalty, if one came | Arguable and case-dependent | It depends on what was entrusted and on what the client provided |
The "in principle" is not a formula: whether it succeeds depends on what the engagement says, on the instructions given and on whether the client provided the right data. If the price appeared correctly in the documents the gestoría received, its position is hard to defend.
How the claim is documented
- The engagement letter or quote showing that the gestoría took on Modelo 211.
- Emails or messages with the data it was given, especially the price.
- The Modelo 211 as filed, with its secure verification code, which shows who filed it and on what base.
- The supplementary return and the surcharge assessment, which fix the loss.
- A written demand to the gestoría asking for an explanation, the return of anything not applied, payment of the loss and the details of its professional liability insurance.
If the gestoría belongs to a professional association, the association usually has a complaints service. The substantive route, if there is no agreement, is a civil claim for breach of the engagement, and the usual thing is for its insurer to respond. We cannot tell you in advance that you will be paid: we can leave you with the file put together so that the conversation is about documents and not about recollections.
When the mistake runs the other way: too much was paid in
The opposite also happens. A gestoría that withholds 3 % on the whole price when one of the two sellers was resident pays in too much, and the one who loses the money is the resident seller, who had it deducted for no reason. Here there is neither surcharge nor penalty: what is called for is an application to rectify the self-assessment so that Hacienda refunds what was unduly paid in, with interest, and it can be made as long as four years have not passed. The buyer files it, the money comes back and is handed to the person it was withheld from. The cost to the client is the fees for the correction and the waiting time, and those are indeed the measure of the loss against whoever made the mistake.
Do not wait until the claim is resolved to file the supplementary return. Each month adds a point of surcharge, and if a request arrives in the meantime, the loss you would be claiming grows and also becomes arguable. File, pay and keep every receipt: they are the exact measure of the damage.
Aisha also has one last duty towards the seller: handing him the receipt for the supplementary return, because with it he can rectify his Modelo 210 and adjust whatever applies to him. If you are in a similar situation and want us to review the Modelo 211 that was filed, the Modelo 211 withholding form lets us ask you for just what we need. And if the doubt is about the calculation, how Modelo 211 is filled in sets out what goes in each box.
