Selling Your Costa Blanca Property as a Non-Resident: the 3% Retention, Taxes and Real Timelines
By Sunset Homes · 9 min read · Updated 2026
On completion day, the buyer will withhold 3% of the price and pay it straight to the Spanish tax office on account of your gain. On a 300,000 € sale, that’s 9,000 € you won’t see at the notary. It’s legal, it’s mandatory for every non-resident seller — and knowing it in advance is the difference between a well-planned sale and a completion full of surprises. Here’s everything to have clear before you list.
At a glance
- 3% retention withheld at completion (form 211) — refundable if your actual gain is smaller.
- Capital gains: 19% on the profit for non-residents.
- Plusvalía municipal: varies by town hall and years of ownership.
- Realistic Costa Blanca selling time: 3–6 months at a market-correct price.
The seller’s three taxes
1. Capital gains (IRNR): 19% on the difference between what you paid (plus invoiced costs and improvements) and what you sell for. Keep every renovation invoice — each documented euro shrinks the taxable base.
2. The 3% retention: not an extra tax, an advance. If your real gain produces a smaller bill than the amount withheld, the Agencia Tributaria refunds the difference once you file form 210 in time. Sold at a loss? The full 3% comes back. Refunds take months — plan for it.
3. Plusvalía municipal: taxes the increase in land value since you bought. Since the 2021 reform you can choose the more favourable calculation method, and a genuine loss means no tax at all. Have your lawyer calculate it before accepting any offer.
The paperwork that speeds up — or stalls — your sale
Foreign buyers, who will be most of your viewings on the Costa Blanca, buy with a lawyer, and that lawyer will ask for: the title deed, the latest IBI receipt, the energy certificate, a community certificate of no debts, and the habitation certificate or second-occupation licence depending on the town. Having the dossier ready before listing cuts weeks off the process. It’s the exact mirror of the due diligence you went through as a buyer.
Pricing: where the months are won or lost
A home listed 10% above market doesn’t sell for more — it goes stale. It sits on the portals for weeks, buyers notice, and the offers come in lower than if it had been priced right on day one. With current international demand — see the market report — a correctly valued property with a complete dossier sells in 3–6 months. Ask for a valuation built on real comparables from your area, not a flattering number designed to win your listing.
Will your buyer be foreign? Almost certainly. Working with an agency that sells in their language and understands their process — post-Brexit UK buyers included — multiplies your qualified viewings.
