A floor clause refund for non-residents in Spain needs a case-specific review. Spain’s Tax Agency states that, for personal income tax (IRPF), the repayment of amounts previously paid under a floor clause, together with corresponding compensatory interest, is not included in the IRPF tax base. That IRPF guidance does not, by itself, decide every non-resident income tax (IRNR) case. Separate the payments and review how the property and earlier returns were treated.
First, separate the amounts in the settlement
A bank statement may show one total, while the supporting agreement distinguishes several items: repayment of excess mortgage interest, compensatory interest, legal costs or other adjustments. Obtain the bank’s calculation, settlement agreement or court decision and identify the amount, date and form of each payment. If the refund reduced the outstanding loan rather than arriving in cash, record that too.
Do not label the whole transfer as taxable income—or assume it is all tax-free—without checking what each item represents and which tax rules apply to you. The legal basis, payment date and history of the loan can matter.
What the official floor-clause guidance says
The AEAT’s current IRPF guidance describes the repayment of amounts previously paid because of a floor clause, together with the corresponding compensatory interest, as outside the IRPF tax base. It also discusses situations where the returned amounts had affected earlier deductions or deductible expenses. This is specifically IRPF guidance. A non-resident should not automatically apply its adjustment mechanism to IRNR or assume it resolves the treatment of every settlement component.
Check the applicable IRNR rules and the tax treaty between Spain and your country of residence for the relevant year. The character of the payment, the recipient, the use of the property and the treaty wording may affect the analysis. Where the official guidance is written for IRPF, treat it as context—not as a substitute for checking IRNR.
Review the property and earlier Form 210 returns
If the property was rented in Spain, review the relevant rental periods and any financing costs claimed in earlier Form 210 returns. For a separate overview of declaring rental income, see our Form 210 rental income guide. Ask whether the refunded amount changes an expense or tax calculation previously reported under the rules that applied to that taxpayer and period. Do not copy the IRPF correction steps without confirming that they apply to the non-resident’s facts and filing history.
If the property was not rented, or the loan costs were never used in a Spanish tax calculation, the review may be different. In either case, keep a clear timeline linking the mortgage, property use, refund and previous filings. That helps distinguish a correction of an earlier calculation from a potentially separate item that needs its own tax analysis.
Does a refund mean you must file Form 210?
Not automatically. Receiving money from a bank does not, on its own, answer whether a new Form 210 is required. First establish whether any component is taxable under IRNR, whether a past return needs review, and whether a treaty changes the result. Then check the current AEAT rules for filing obligations, deadlines and any correction or refund procedure.
Keep the mortgage agreement, payment history, bank settlement, any court or arbitration decision, rental records, prior tax returns, and evidence of tax residence. These documents help an adviser distinguish the amounts and apply the rules for the correct period.
