Capital gain on Spanish property sale is taxed differently for residents (progressive Spanish rates on worldwide gain) and non-residents (flat non-resident rate on Spanish-located gain). Non-residents face a 3% retention at sale, reconciled in the next filing.

Frequently asked questions
Is the 3% retention refundable if my actual CGT is lower?
Yes — the retention is a pre-payment. File Modelo 210 after sale and reclaim the excess. Costaluz handles this reclamation.
Does plusvalía municipal always apply?
Post-Constitutional-Court ruling, plusvalía is only due if there’s a real gain in value. Where there’s a loss, plusvalía should not apply — but some ayuntamientos still try to charge.
Can I deduct renovation costs from the gain?
Only if they qualify as improvements (not maintenance) and are properly invoiced. Documentation matters: invoice + payment trace + contractor’s tax ID.
Does the Spain–UK DTT change how UK residents are taxed on Spanish property gains?
Generally the Spanish tax right is preserved (property in Spain → Spain taxes first); UK gives credit against UK CGT. The interaction depends on residency timing and specific property type.
What does Costaluz charge for sale conveyancing + CGT filing?
Flat fee covering sale, Modelo 210, plusvalía review, and 3% retention reclaim. Email marialuisa@costaluzlawyers.es.
