Chloé is French and has lived in Málaga since 2019. On 3 June 2026 her father, who lives in Lyon, transferred €60,000 to her for the deposit on a flat. Nobody told her about Modelo 651, the gift tax return. She found out in September, when the notary's office handling the purchase asked her to show where the money came from. The deadline for declaring the gift ended in mid-July. The surcharge for filing now is small. What is really at stake is something else: whether the delay, or the way the gift was made, costs her the tax relief her autonomous community (her Spanish region) provides between parents and children.
Who had to file, where and by when
In the Impuesto sobre Sucesiones y Donaciones, the inheritance and gift tax governed by Ley 29/1987, the taxpayer on a gift is the donee: the person who receives, not the person who gives. Chloé is resident in Spain, so she is taxed here on what she receives, wherever the money comes from. The autonomous community with competence over a gift of money is the one where the donee has her habitual residence, measured by the days spent there in the previous five years: Andalucía. The allocation is explained in the table of competences for the ISD (the Spanish initials of the tax).
The deadline is thirty working days from the day after the gift. Working days exclude Saturdays, Sundays and public holidays, so it is not the same as a month. Counting from 4 June 2026, the thirtieth working day falls around 15 July, subject to checking local holidays. With gifts there is no extension of the kind that exists for inheritances. The detail of the count is in deadlines and extension in the ISD.
Two risks of very different size
| Risk | What it depends on | Order of magnitude |
|---|---|---|
| Surcharge for filing late | Full months of delay, under article 27 of the Ley General Tributaria, Spain's General Tax Act | A small percentage of the resulting tax |
| Losing the regional relief | The requirements set by the community's law for the reduction or rebate between parents and children | It can be almost the whole tax |
| A penalty if Hacienda moves first | A requerimiento, a formal request from the tax authorities, arriving before filing | From 50 % of the tax upwards, with its reductions |
The first row is the one that frightens people and the one that matters least. The second is the one that has to be read in the community's legislation before filling anything in.
The figure, with two scenarios
We do not give relief percentages here, because they change by community and by year and have to be read in the law in force on the day of the gift. But the mechanism can be seen with two assumed tax figures. Let us imagine that, once the scale and the reductions are applied, Chloé's tax would be €7,400 with no regional relief at all, and €150 if the relief applies.
- End of the period: around 15 July 2026.
- Filing: on 25 September. Full months from the day after the end of the period: two (at 15 August and at 15 September).
- Surcharge: the recargo, the surcharge for filing late unprompted, of 1 % + 2 points = 3 %.
- Scenario A, relief applied: tax of €150, surcharge of €4.50, which comes down to €3.38 with the 25 % reduction.
- Scenario B, relief lost: tax of €7,400, surcharge of €222, €166.50 reduced. Total: €7,566.50.
The difference between the two scenarios is more than €7,000, and almost none of it is surcharge. It is all the relief.
What has to be read in the community's law
Communities usually make their gift relief conditional on formal requirements. Some that appear often, and which have to be checked in the specific legislation:
- That the gift is formalised in a public deed before a notary. A bank transfer, like Chloé's, is not a deed.
- That, for gifts of money, the origin and destination of the funds are proved through banking records.
- That the money is put to a specific purpose, such as buying the main home, within a set period.
- That the relief is applied in a self-assessment filed on time. Not all communities require it, but if yours does, the delay is what decides it.
If the requirement is the deed, it can sometimes be executed afterwards, acknowledging the gift already made; whether that late deed is valid for the relief is a question that has to be answered with the regional legislation in hand. We deal with it in more detail in international gifts and relief.
Spain taxing the gift to Chloé does not prevent France from having something to say about the same gift, because the donor lives there. We do not give opinions on French law: if the donor has an adviser in France, the reasonable course is for that adviser to look at it, and we coordinate with whoever the donor appoints on whatever has to be proved in Spain.
Why the notary asked, and why that matters
Chloé found out because the notary's office asked her about the source of the funds. That was no coincidence: significant inflows of money and home purchases generate information that reaches the tax authorities, and article 4 of Ley 29/1987 allows a gratuitous transfer to be presumed when the wealth of one family member goes down and that of another goes up. If the letter from Hacienda (the tax authorities) arrives before the return, the surcharge disappears and penalty proceedings are opened. What counts as a letter for these purposes is explained in what counts as a prior request.
Several transfers, several deadlines
Had Chloé's father sent the money in three transfers of €20,000, in June, July and August, there would not be one gift but three, each with its own date and its own thirty-working-day period. They could be declared together at the time of putting things right, but each would carry its own delay and its own surcharge percentage, and the three would be added together to calculate the rate, because the law adds up gifts from the same donor to the same donee over three years. Splitting the transfer does not lower the tax and multiplies the deadlines to watch.
The papers worth gathering
For a gift of money from abroad, you will normally need identification of donor and donee, proof of the relationship, which for a father and daughter is usually the libro de familia (the Spanish family record book) or its foreign equivalent, translated, and the bank records of the sending and the receipt. Depending on the administration, a Spanish identification number for the donor may also be requested. If the father does not have one, it is worth finding out early, because obtaining it from France takes time and the surcharge keeps adding months.
The order we would follow in this case
- Fix the exact date of the gift from the transfer statement: that is when the tax falls due.
- Confirm the competent community by counting the days of residence over the previous five years.
- Read the requirements for the relief in the regional law in force in June 2026 and check which are met.
- Decide whether a deed acknowledging the gift is called for before filing.
- File Modelo 651 with the real date, even if the tax comes out low: the return is filed all the same.
- Keep the carta de pago, the payment receipt: the notary's office handling the purchase is going to ask for it.
If you are in a similar situation, the inheritance and gift form is the way for us to look at it before you file. And the page on inheritances and gifts covers the rest of the tax.
