You’ve found the apartment. You love the area. Now the question that every serious British buyer on the Costa del Sol eventually faces: is this a holiday home, or are we actually moving?
It feels like a lifestyle question. It is also a significant financial one. The same €380,000 property on the Costa del Sol costs materially different amounts to own depending on which side of the 183-day line you sit on — and the wrong assumption at the outset can mean unexpected tax bills, the wrong mortgage structure, or a healthcare situation you did not plan for.
This guide runs the real numbers for both scenarios, side by side, so you can make the decision with clear eyes.
The 183-Day Line: What Triggers Spanish Tax Residency
Spain classes you as a tax resident if you spend more than 183 days in Spain in a calendar year, or if your main economic interests are based in Spain. Cross that line and you are taxed in Spain on your worldwide income — not just your Spanish income.
Stay below it and you are a non-resident. You still have Spanish tax obligations (primarily Form 210 on your property), but your UK income stays with HMRC.
This is the fork. Everything else — tax rates, healthcare, mortgage terms, annual running costs — flows from which side of it you are on.
The Tax Picture: Non-Resident vs Resident
As a non-resident (holiday home)
Your main ongoing Spanish tax obligation is Form 210, the non-resident property tax return. Even if you do not rent the property out, you owe imputed income tax each year — HMRC assumes you are earning a notional “income” from having the property available to you.
The calculation: 1.1% of the cadastral value (the figure on your IBI bill) × 24% (the non-EU/non-EEA rate for UK owners post-Brexit). On a €380,000 apartment with a typical cadastral value of €160,000, that works out to roughly €422 per year.
If you do rent the property out, you pay 24% tax on gross rental income with no expense deductions — unlike EU/EEA owners who pay 19% on net income. A property earning €15,000 per year in rent would generate a Spanish tax bill of €3,600/year before any UK reporting obligations.
Form 210 must be filed quarterly if you are receiving rental income, or annually (by 31 December) for imputed income. Most owners pay a gestor €400–600/year to handle this.
As a tax resident (permanent move)
Become resident and your worldwide income is taxed in Spain under IRPF (Spain’s income tax). The rates are progressive:
| Spanish taxable income | Rate |
|---|---|
| Up to €12,450 | 19% |
| €12,451 – €20,200 | 24% |
| €20,201 – €35,200 | 30% |
| €35,201 – €60,000 | 37% |
| €60,001 – €300,000 | 45% |
| Above €300,000 | 47% |
Your UK pension, rental income, ISA returns and any other income all become declarable. The UK-Spain double tax treaty prevents double taxation, but the gap between UK and Spanish marginal rates can bite higher earners.
One significant upside: if you qualify for Spain’s Beckham Law (the Régimen Especial de Impatriados — available to people who move to Spain for work under a new employment contract or as self-employed with qualifying income), you pay a flat 24% on all Spanish income up to €600,000 for six years. This can be substantially cheaper than IRPF for higher earners. Full Beckham Law guide here.
For retirees moving permanently, the tax picture requires careful modelling with a dual-qualified tax adviser before you commit. Modelo 720 (a declaration of overseas assets worth over €50,000) is also required annually by 31 March — missing it carries heavy penalties.
Annual Running Costs: Same Property, Different Bills
The property costs that don’t change with residency status:
- IBI (local property tax): €400–800/year on a €380,000 apartment in most Costa del Sol municipalities
- Community fees: €1,200–4,800/year depending on complex (pool, garden, concierge, parking)
- Buildings insurance: €300–600/year
- Utilities (even when the property is empty, standing charges apply): €400–700/year
What changes depending on residency:
| Cost | Non-resident | Resident |
|---|---|---|
| Form 210 / IRPF prep | €400–600/year (gestor) | €600–1,200/year (gestor or asesor) |
| Form 210 imputed tax | €350–650/year | N/A (property income declared in IRPF instead) |
| Health insurance | GHIC card (visitors) or private | Private required for NLV/DNV; public after 1 year residency |
| Modelo 720 | Not required | Required if overseas assets >€50k |

Healthcare: The Biggest Practical Difference
This is where the two scenarios diverge most sharply in day-to-day terms.
Holiday home owners rely on the GHIC card (Global Health Insurance Card — the post-Brexit replacement for the EHIC) for emergency treatment when visiting Spain. The GHIC covers urgent and necessary medical treatment at the same cost as Spanish nationals, but it is not health insurance — you cannot use it for planned treatment, repatriation, or anything beyond the immediate need.
If you spend months in Spain on a tourist entry, you are relying on private travel insurance for anything serious. A good annual multi-trip travel policy costs £200–600/year, but it typically limits stays per trip to 30–60 days.
Permanent residents have two routes:
1. Private health insurance — required as a condition of the Non-Lucrative Visa (NLV) and the Digital Nomad Visa. Costs £100–250/month per person depending on age and insurer (Sanitas, Adeslas, Asisa, DKV are the main providers). Coverage is comprehensive and allows you to access excellent private hospitals like Quirón Marbella or Vithas Xanit directly.
2. Spanish public healthcare — once you have been resident and contributing to the Spanish social security system for 12 months (through work or, for pensioners, via the S1 form from the UK’s DWP), you can register with a Spanish GP. UK state pensioners with an S1 form can access Spanish public healthcare immediately upon registration.
For everything you need to know about which route applies to your situation, see our Costa del Sol healthcare guide for British residents.
Mortgage Terms: Non-Resident vs Resident
If you are buying with a mortgage, your residency status affects what you can borrow.
Non-resident mortgages: Spanish lenders typically lend up to 60–70% LTV for non-residents. On a €380,000 purchase, that means a minimum deposit of €114,000–€152,000 (before buying costs). Rates are comparable to resident mortgages — typically 3.2–4.1% variable or 3.5–4.5% fixed over 20–25 years — but the lower LTV means you need more cash upfront.
Resident mortgages: Up to 80% LTV is standard, and some lenders go to 85% for residents who meet income criteria. The same €380,000 purchase would require a minimum deposit of €57,000–€76,000 before costs.
This matters most if you are near the limit of what you can put down. Cash buyers are unaffected.
Capital Gains When You Sell: The Exit Picture
When you eventually sell, the Spanish tax treatment is the same regardless of residency: you pay 19% CGT (IRNR for non-residents, IRPF CGT rate for residents) on the taxable gain.
The key difference is the 3% withholding rule. When a non-resident sells Spanish property, the buyer is legally required to withhold 3% of the sale price and pay it directly to the Spanish tax authority. If your actual CGT is less than 3% of the sale price — which is common when selling a property after significant price appreciation — you reclaim the difference.
For residents, there is no 3% withholding. You declare the gain in your annual IRPF and pay at the end of the tax year.
Both scenarios require UK reporting too: HMRC requires CGT reporting within 60 days of completion on a UK return. The UK-Spain double tax treaty provides relief to prevent you paying CGT in both countries on the same gain.

The Five-Year Numbers: Holiday Home vs Permanent Move
Assumptions: €380,000 apartment, bought for cash, medium-spec gated development in Estepona, IBI €540/year, community fees €2,400/year, not rented out.
| Cost | 5-year holiday home total | 5-year permanent move total |
|---|---|---|
| IBI | €2,700 | €2,700 |
| Community fees | €12,000 | €12,000 |
| Buildings insurance | €2,250 | €2,250 |
| Utilities (standing + use) | €4,500 | €8,000 |
| Gestor / tax adviser | €2,750 | €5,000 |
| Form 210 imputed tax | €2,110 | — |
| IRPF on UK income (est.)* | — | Varies — model with adviser |
| Health insurance | £1,500 travel insurance | €12,000 private insurance |
| Total (property costs only) | ~€26,310 | ~€29,950+ |
*IRPF impact on UK income is the largest variable and must be modelled individually.
The property-level running costs are similar. The real financial delta comes from the income tax impact on your existing UK income streams — pensions, rental income, investment returns. For many retirees, this makes careful planning essential before crossing the 183-day line.
If you are thinking about the permanent move in retirement specifically, the retiring to Spain financial checklist covers the full picture including NLV income thresholds, Modelo 720, and how to handle UK state pension and private pension taxation.
For context on day-to-day living costs — groceries, eating out, transport — the Costa del Sol vs UK cost of living comparison shows typical monthly budgets for both sides of the move.
Which Is Right for You?
A holiday home makes sense if:
- You want to keep your UK life as the primary base
- You will spend fewer than 183 days per year in Spain
- Your income sources are UK-based and you want to keep HMRC as your primary tax authority
- You plan to rent the property out for significant periods (though note the 24% gross rental tax rate)
Permanent residency makes sense if:
- You are retiring and Spain will genuinely become your main home
- You qualify for the Beckham Law or have income that falls into lower Spanish tax brackets
- You want full access to the Spanish healthcare system
- You plan to spend more than half the year in Spain regardless
Get professional advice before the 183-day clock starts. The tax implications of crossing the residency threshold mid-year can be complex, and the planning is much easier done before the move than after.
