Rental Income Tax in Thailand: What Every Foreign Landlord Pays in 2026

A foreign investor renting out a condo in Phuket for 50,000 baht per month hands between 5% and 35% of that income to the Thai government. The exact figure depends on total annual income, tax residency status, and whether a tax return is filed. Most international landlords overpay simply because they never submit an annual declaration and quietly accept withholding tax as a final settlement.

Thailand taxes rental income under a progressive Personal Income Tax (PIT) scale. The first 150,000 baht of annual income is fully exempt. Rates then climb from 5% to 35%. The complication: when income is paid to a non-resident, the management company or tenant is legally required to deduct withholding tax at source on every payment. This mechanism is the single biggest source of confusion for foreign property owners.

Quick Answer

• Thailand applies a progressive PIT scale: 0% on income up to 150,000 baht, rising to 35% above 5 million baht
• Withholding tax on rental income for individuals is 5% of each payment at source
• Thai tax residency applies to anyone present in the country for 180 days or more in a calendar year
• Rental income can be declared with a flat 30% expense deduction - no receipts required
• A double taxation agreement (DTA) between Thailand and Russia has been in force since 1999
• The PND 90 tax return deadline for foreign individuals is 31 March of the following year

Scenarios and Options

Scenario 1: Non-Resident Renting Through a Management Company

This is the most common arrangement for foreign investors. The management company deducts 5% withholding tax from every rental payment and remits it directly to the Revenue Department. The investor receives the net amount.

The hidden issue: if annual rental income is below 500,000 baht, the effective PIT rate after allowable deductions can be well below 5%. But reclaiming the overpaid amount requires filing a PND 90 return. Most non-residents skip this step and forfeit real money each year.

Worked example. A Phuket condo generates 40,000 baht per month (480,000 baht per year). The management company withholds 5%, which equals 24,000 baht annually. On declaration: subtract the 30% flat expense deduction (144,000 baht) and the 60,000 baht personal allowance. Taxable base: 276,000 baht. The first 150,000 baht is tax-free. The remaining 126,000 baht at 5% produces a tax bill of 6,300 baht. The overpayment is 17,700 baht - nearly three months of management fees returned to the investor.

Scenario 2: Tax Resident Filing Independently

Investors who spend more than 180 days per year in Thailand become tax residents. This unlocks the full deduction schedule and lower effective rates on lower income bands. However, since the Revenue Department Ruling Por. 161/2566 took effect (2024 income year onwards), Thai tax residents must also declare foreign-source income remitted to Thailand within the same calendar year.

When renting independently to a corporate tenant, withholding tax still applies. If the tenant is an individual (a tourist or expat), no automatic deduction occurs. The landlord must calculate and pay PIT directly.

Scenario 3: Renting Through a Thai Company (Thai Co., Ltd.)

Some investors incorporate a Thai limited company to hold and lease property. Corporate Income Tax (CIT) is 20% of net profit. Small companies with annual income below 300,000 baht pay 0%; income from 300,001 to 3 million baht is taxed at 15%.

The offsetting cost: dividends paid to a foreign shareholder attract 10% withholding tax. Combined taxation at company level and shareholder level can erode the advantage for most small portfolios.

Main Risks and Mistakes

1. Ignoring the annual tax return. Withholding tax deducted at source is an advance payment, not a final settlement. Without submitting form PND 90, overpaid tax cannot be reclaimed. Industry estimates suggest more than 70% of foreign landlords never file, losing between 10,000 and 50,000 baht each year.

2. Confusing withholding tax with PIT. Withholding tax is a collection mechanism. The amount withheld is credited against the final PIT liability. If the PIT owed is less than what was withheld, the Revenue Department issues a refund of the difference.

3. Overlooking the 30% flat deduction. Individual landlords may deduct 30% of gross rental income without any supporting receipts. This covers implied maintenance, depreciation, and utilities. Many investors calculate tax on the full rental amount and overpay accordingly.

4. Not applying the double taxation agreement. The Thailand-Russia DTA (signed 1999) specifies that income from immovable property is taxed in the country where the property is located (Article 6). Tax paid in Thailand can be credited against Russian personal income tax obligations. A Certificate of Tax Residence issued by the Thai Revenue Department is required to make the credit claim.

5. Operating without a Thai Tax ID. Any person earning income in Thailand must register for a Tax Identification Number (TIN). Registration requires one visit to the local Revenue Department office with a passport and rental agreement or title deed copy.

6. Choosing a management company without transparent reporting. Some operators do not issue a withholding tax certificate (Form 50 Tawi). Without this document, the investor cannot prove that tax was deducted and cannot file a return.

FAQ

What tax does a foreign national pay on rental income in Thailand? Progressive Personal Income Tax at rates from 0% to 35%. When a management company collects rent on your behalf, an advance 5% withholding tax is deducted from each payment.

How does the Thailand-Russia double taxation agreement work in practice? Tax paid to Thailand is credited against Russian personal income tax under the 1999 DTA. You need a Thai Certificate of Tax Residence and proof of payment (Form 50 Tawi) to support the credit claim.

Is it better to rent as an individual or through a Thai company? For one or two properties with annual income below 2-3 million baht, an individual structure is more efficient: the 30% flat deduction, 60,000 baht personal allowance, and simple administration give a lower effective rate. A company structure becomes worthwhile for portfolios of three or more properties generating above 5 million baht annually.

Does income from Airbnb listings need to be declared in Thailand? Yes. Short-term rental income through platforms such as Airbnb, Booking.com, or Agoda is taxed on the same terms as long-term rental income.
