How to Declare a Lottery Prize Shared in a Pool to the Tax Office
Why do you need to declare a prize won as a group?
Quick answer: For a lottery prize shared in a syndicate (peña) to be taxed by share, you must show the paying bank who takes part and in what percentage, with each person’s name and ID. Each participant pays tax on their share, but the €40,000 exemption applies per ticket or bet and is divided among everyone: the total tax is the same as if one person claimed it, but the claimant avoids later having to justify a gift.

Example: tenth winning the Christmas El Gordo (€400,000) shared equally
| Participants | Each receives | Exemption per person | Tax per person | Net per person |
|---|---|---|---|---|
| 1 | €400,000 | €40,000 | €72,000 | €328,000 |
| 2 | €200,000 | €20,000 | €36,000 | €164,000 |
| 4 | €100,000 | €10,000 | €18,000 | €82,000 |
| 10 | €40,000 | €4,000 | €7,200 | €32,800 |
When a group of people shares a winning ticket, the tax authorities need to know how much of the prize belongs to each participant, since the special lottery prize tax is calculated individually on the amount each person receives, not on the total prize.
The key document: the prize-split agreement
To officially split a prize among several people, it is necessary to sign a document before a notary, or submit one to the paying entity, stating the name, ID number and percentage or amount corresponding to each member of the group. This step is essential so each person is taxed only on their own share.
How is each participant taxed?
Once the prize is split, each participant is taxed on their share, but the €40,000 exemption applies per ticket or bet, not per person: it is divided in proportion to each person’s share. For example, if four people share a tenth winning the Christmas El Gordo (€400,000) equally, each receives €100,000, gets a €10,000 exemption and pays 20% of €90,000, i.e. €18,000.
Recommendations for lottery pools
- Put in writing, before the draw, who is part of the pool and in what proportion
- Keep proof of each participant's contribution
- Bring all the documentation to the paying entity before claiming the prize
- Consult a tax advisor if the prize is a large amount
Conclusion
Correctly declaring a prize shared within a group avoids future problems with the tax authorities and ensures each participant is taxed only on their actual share. Getting organised from the start is the best way to enjoy the prize without surprises.
Frequently asked questions
Is the €40,000 exemption per person on a shared prize?
No. The exemption applies per ticket or bet and is divided in proportion to each person’s share. If four people share a tenth, each gets €10,000 tax-free.
What documents are needed to split a syndicate prize?
A document with each participant’s name, ID and percentage, presented to the paying bank when claiming. Ideally it should be put in writing before the draw.
What happens if one person claims the whole syndicate prize?
They are taxed on the total and, if they then share the money without having proved co-ownership, the tax authority could treat those payments as gifts subject to gift tax.
Do I have to include the prize in my income tax return?
No, if the bank has already withheld the 20%: the special tax is settled at payment and the prize is not added to your taxable income.
How can I prove a ticket was shared?
With the split document, proof of each contribution (transfers, Bizum, messages) and, if shares were bought, each participant’s share slips or receipts.
