Rental income from Thai property is taxable in Thailand regardless of where the owner lives. The mechanics are well-defined: a 30% standard deduction off gross rent (or actual expenses), Thailand’s progressive personal income tax brackets, mid-year and annual filings. The complications come at the edges — non-resident owners face a flat 15% withholding default that’s usually worse than filing properly, and short-stay rentals can trigger VAT registration alongside the Hotel Act exposure.
This article covers the full tax treatment for foreign property owners earning rental income from Phuket and other Thai property.
The base — what counts as rental income
Thai-source rental income includes:
- Long-term residential leases (1+ year tenants)
- Short-term rentals (Airbnb), Booking.com, daily/weekly
- Furnished and unfurnished
- Direct-to-tenant or via property management
- Rent paid in THB or in any other currency (converted to THB at receipt)
The taxable income is the gross rent received. Returnable security deposits are not income. Pre-paid rent is income in the year received. Tenant-paid utilities billed at cost are usually not income (verify with your accountant); markups are.
Thai-source rental income is always taxable in Thailand — including for non-resident owners, owners abroad most of the year, and owners who never visit Thailand. The property is in Thailand; the rent is Thai-source.
The 30% standard deduction
Thai personal income tax law gives landlords a choice between:
Option 1 — 30% standard deduction. Automatic, no documentation required. Covers maintenance, repairs, depreciation, property management fees, insurance, and other holding costs. Apply to gross rent; the remaining 70% is the deemed net rental income.
Option 2 — Actual documented expenses. Track actual costs with receipts: management fees, CAM, sinking fund contributions (annualized), utility deductions, property tax, insurance, maintenance, advertising, depreciation. The total deductible amount is the actual deduction.
For most foreign owners, the 30% standard is simpler and often higher than actual costs would be. Only switch to actuals if you have reason to believe your real costs exceed 30% — e.g., significant renovation work, major management fees, or specific high-cost circumstances.
Progressive PIT brackets
After the deduction, the net rental income is added to the landlord’s total Thai-assessable income and run through Thailand’s progressive personal income tax brackets:
| Net assessable income | Marginal rate |
|---|---|
| 0–150,000 THB | 0% |
| 150,001–300,000 | 5% |
| 300,001–500,000 | 10% |
| 500,001–750,000 | 15% |
| 750,001–1,000,000 | 20% |
| 1,000,001–2,000,000 | 25% |
| 2,000,001–5,000,000 | 30% |
| 5,000,001+ | 35% |
The first THB 150,000 of net assessable income is exempt. Personal allowances (THB 60,000 personal, plus dependents) further reduce the taxable base.
For most foreign owners renting one property, the rental income falls in the 5%–15% marginal bracket — and after the 30% deduction and the 150k exemption, the effective tax rate is typically 5%–10% of gross rent.
The two filings — PND.94 and PND.90
Thai personal income tax requires two filings for landlords:
PND.94 — half-year return, due 30 September of the current year. Reports income earned January–June. Tax paid is a prepayment of the annual obligation.
PND.90 — full-year return, due 31 March of the following year. Reports total income (full year) including the half-year reported on PND.94. Final tax owed is calculated; PND.94 prepayment is credited; balance is paid (or refund claimed).
Both filings are made at the local Revenue Department office, online via the e-Filing system, or through a tax agent. Foreign owners typically use a tax agent — fees THB 5,000–15,000 per filing for routine returns.
Tenant withholding — the 5% complication
When a Thai company tenant pays rent to an individual landlord, the tenant must withhold 5% of the rent and remit it to the Revenue Department. The tenant gives the landlord a withholding certificate. The landlord credits this withholding against their final tax owed on PND.90.
This applies only when the tenant is a Thai juristic person — not when the tenant is an individual. For foreign owners renting to individuals (typical for residential), no tenant withholding applies.
For owners renting to corporates (serviced-apartment-style, business tenants), the 5% appears in your Thai bank account as net rent, and you reclaim through PND.90 filing.
Non-resident landlord — the flat 15% default
If a foreign landlord has no Thai tax filing, the law applies a default flat 15% withholding tax on Thai-source rental income. This is high — for most landlords, it’s more tax than the proper PND.90 calculation would produce.
The fix: get a Thai Tax ID and file PND.90 normally. The Tax ID is issued by the Revenue Department; the application takes a day or two. Once you have a TIN, you can file PND.94 and PND.90 like a resident landlord, claim the 30% deduction, run through progressive brackets, and pay the actual (lower) tax.
The mechanics for a non-resident filer are essentially the same as for a resident, except:
- You file as a non-resident, which limits some allowances
- You don’t claim Thai-resident-specific tax credits
- You may need to file even if your Thai-source income is below the resident filing threshold
For owners spending less than 180 days/year in Thailand: file as non-resident. For owners spending 183+ days: file as resident (which has its own implications — see “Tax residency” below).
Tax residency — the 180-day question
Thailand treats you as a tax resident if you spend 183 or more days in Thailand in a calendar year. Tax residents are taxed on:
- Worldwide income to the extent remitted to Thailand (the remittance rules changed sharply in 2024 — see below)
- All Thai-source income
Non-residents are taxed only on Thai-source income.
For property owners specifically, rental income is Thai-source regardless of residency. The 183-day question affects how your other income (foreign salary, dividends, capital gains) is treated, not your rental income.
The 2024 change: Revenue Department Order Por. 161/2566 (effective 1 January 2024) closed the long-standing loophole where foreign income remitted to Thailand was tax-free if brought in after the calendar year it was earned. From 2024, any foreign income remitted by a Thai tax resident is taxable regardless of when earned. LTR visa holders are exempt from this remittance tax — see Thailand LTR visa for property buyers — qualifying with a USD 500k investment.
Foreign owners filing Thai rental income should also note that Thai banks report account balances and income to the owner’s home tax authority under the OECD Common Reporting Standard and (for US persons) FATCA — see Thailand property and CRS / FATCA reporting for foreign owners for the practical implications of declaring Thai rental income that’s already reported abroad.
VAT — the 1.8M THB threshold
Pure residential rental (lease of immovable property) is exempt from VAT. Long-term tenants paying rent for a residence trigger no VAT.
VAT becomes mandatory when the rental activity is treated as hotel or serviced-apartment business — typically when:
- Rental terms are short-term (under 30 days, daily/weekly)
- Services are provided alongside (cleaning, breakfast, concierge, daily towel/linen change)
- The property is operated hotel-style
When the activity counts as VAT-able and gross revenue exceeds THB 1.8 million per year, VAT registration is mandatory. The 7% VAT then applies to all rental revenue from that point. The owner can claim input VAT on certain expenses.
The 1.8M threshold is per owner, across all properties. For owners with multiple short-term-rental units exceeding the threshold, registration is unavoidable.
For Phuket short-term rental investors: the VAT threshold combines with the Hotel Act exposure. Operating short-term rentals above 1.8M revenue without VAT registration adds tax-fraud exposure on top of the unlicensed-hotel exposure.
Old House and Land Tax — abolished
Thailand previously had a House and Land Tax (12.5% of annual rental value). This was abolished by the Land and Building Tax Act 2019 — replaced by the Land and Building Tax which is much lower (~0.02% of appraised value for most foreign-owned condos) and applies to ownership rather than rental income.
Some older online sources still reference the 12.5% rate. It does not exist anymore. Don’t double-count.
Worked examples
Example 1 — Resident foreign owner, 1 property, 800k THB annual rent
- Gross rent: 800,000
- 30% standard deduction: -240,000
- Deemed net rental: 560,000
- Personal allowance (single): -60,000
- Net assessable income: 500,000
- PIT calculation:
- 0–150,000 at 0% = 0
- 150,001–300,000 at 5% = 7,500
- 300,001–500,000 at 10% = 20,000
- Total: 27,500
- Effective tax on rental: ~3.4% of gross rent
Example 2 — Non-resident foreign owner, 1 property, 800k THB annual rent, no Thai filing
- Gross rent: 800,000
- Flat 15% WHT: 120,000
- Effective tax: 15% of gross
The non-filer pays nearly 5x more tax than the proper-filer in this example. The case for filing is strong.
Example 3 — Resident foreign owner, 2 properties, total 2.5M THB rent, 1.8M of which is short-term
- Gross rent: 2,500,000
- 30% standard deduction: -750,000
- Net rental: 1,750,000
- Personal allowance: -60,000
- Net assessable income: 1,690,000
- PIT calculation:
- 0–150k at 0%, 150–300k at 5%, 300–500k at 10%, 500–750k at 15%, 750k–1M at 20%, 1M–1.69M at 25%
- Total: ~258,000
- VAT exposure: short-term portion (1.8M) at threshold — VAT registration may be required, adds 7% on the short-term portion = ~126,000
- Combined effective tax: ~15% of gross including VAT
The short-term-rental portion drives much of the complexity in the higher-revenue case. Long-term rental keeps tax simpler.
Common foreign-owner mistakes
1. Not filing at all. Hoping the Revenue Department won’t notice. The Department is increasingly cross-referencing rental listings with tax filings; non-filers face back-tax assessments with penalties.
2. Filing only annually (PND.90) without the half-year (PND.94). PND.94 is required for landlords with significant rental income. Skipping it triggers penalties.
3. Treating short-term as long-term for tax purposes. The Revenue Department audits rental classifications. Daily/weekly bookings are short-term and trigger different VAT and Hotel Act analysis.
4. Claiming both the 30% standard deduction and actual expenses. It’s one or the other. Pick the higher one.
5. Not getting a Thai Tax ID. The TIN application is straightforward and unlocks proper filing. Operating without one defaults to the 15% flat rate.
6. Not declaring at the home country. Many foreign owners must also report Thai rental income to their home tax authority (US, UK, Australia, etc.). Tax treaties often provide credits for Thai tax paid, but the obligation to declare typically remains.
What this means for buyers in 2026
Three rules:
-
Get a Thai Tax ID and file PND.94/PND.90 properly. The 5–10% effective tax under proper filing is much better than the 15% flat WHT for non-filers.
-
Use the 30% standard deduction unless you have specific reasons not to. Simpler, usually higher than actual costs.
-
Track short-term vs long-term rental separately. Different tax treatment, different VAT exposure, different Hotel Act exposure. Mixing them in your records creates audit problems.
