**By filing a Modelo 210 for the sale: each seller, within three months after the buyer's one-month window.** When the tax on your gain is less than the 3% withheld, the tax office refunds the difference; after a loss, all of it. Without the return, the money stays with the tax office.

**Example:** a sale in mid-March. The buyer pays the 3% by mid-April, and your return is due between mid-April and mid-July.

- The refund goes to an account in your own name, in Spain or abroad.
- You need the receipt number of the buyer's Modelo 211.
- Non-resident tax rules set no deadline for the refund; six months after your filing window ends, the tax office owes you interest if the delay is its own.
- If your tax is more than the 3%, you pay the difference with the return, by transfer, card or at a Spanish bank: there is no direct debit after a sale.
