The change in status
While you're a tax resident in Spain, your rental income goes through personal income tax with the well-known 60% reduction on net housing income and with deductible costs (mortgage, property tax, community fees, repairs, depreciation). As soon as you stop being a tax resident and move to Thailand, you fall under a different tax: the IRNR (Non-Resident Income Tax), filed with form 210.
The 24% that hurts
Here's the detail that changes the decision for a lot of people. The IRNR rate depends on where you live:
| Resident in… | Rate | Deducts costs? |
|---|---|---|
| Spain (income tax) | Progressive | Yes + 60% reduction |
| EU / EEA | 19% | Yes, on the net amount |
| Thailand (outside EU/EEA) | 24% | No: on the gross amount |
Since Thailand is outside the EU and the EEA, you're taxed at 24% on the gross rental income: no deducting the mortgage, property tax, community fees or repairs. A €1,000/month rental means €240 of tax a month, whatever your mortgage looks like. It's the fine print that turns "I'll keep the property rented" into a very different sum.
An example with numbers
| Property rented for €12,000/year | Resident in Spain | Resident in Thailand |
|---|---|---|
| Taxable base | Net after costs and 60% reduction | €12,000 (gross) |
| Rate | Marginal income tax rate | 24% |
| Approximate tax | Low (reduced base) | ≈ €2,880/year |
The figures are illustrative — your marginal rate and your costs drive the real number — but the message is clear: the same property, the same tenant, a very different tax bill depending on where you live.
And in Thailand, again?
You don't pay twice on the same income: the 1997 double taxation treaty means real estate income is taxed where the property is (Spain), and Thailand takes that into account if the income reaches the country. The net result depends on your overall income mix.
The practical side of form 210
- Form 210 is filed per rental payment; staying on top of it avoids surprises piling up.
- If you sell the property as a non-resident, the capital gain is also taxed in Spain, and the buyer withholds an amount on account.
- The IRNR has its own deadlines and boxes; a mistake on the filing gets expensive.

Frequently asked questions
How is my rental income taxed?
Through the IRNR (form 210). Living in Thailand, outside the EU/EEA, the rate is 24% on the gross income, with no deductions and no 60% reduction.
Why can't I deduct costs?
The cost deduction and the 60% reduction are reserved for EU/EEA residents. A resident of Thailand falls outside that, so you're taxed on the gross amount.
Do I also declare it in Thailand?
The income you remit enters the Thai system, but the 1997 treaty avoids double taxation: what you've paid in Spain is taken into account.
