Rental Income Tax for Property Owners in Thailand

You bought a condo in Bangkok as an investment. You rent it out for 40,000 baht per month. The revenue looks good on paper. Then you realize you’re not sure what you actually owe in taxes.

Thailand taxes rental income, but not the way most Western countries do. There’s personal income tax. There’s withholding tax. There’s property tax. There are deductions you might not know about. And foreign property owners face additional complications.

The basics: progressive tax rates, a generous standard deduction, and annual filing by March 31. The details matter more than you’d think.

How Thailand Taxes Rental Income

Rental income in Thailand is treated as personal income, subject to progressive tax rates. If you’re earning rental revenue, you’re required to report it and pay tax on it.

Basic framework:

Rental income is taxable personal income
Tax is calculated on net income (gross rent minus allowable deductions)
You file annually with your personal income tax return
Rates follow Thailand’s progressive personal income tax scale

This means your rental income is taxed together with any other income you earn in Thailand, not as a separate category with different rates.

Thailand’s Progressive Personal Income Tax Rates (2026)

Thailand uses a progressive tax system. The more you earn, the higher the rate on income above each threshold.

Net Annual Income	Tax Rate
Up to ฿150,000	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%
Over ฿5,000,000	35%

These rates apply to your total taxable income, including rental income. If you’re already earning other income in Thailand, your rental revenue gets added on top and taxed at your marginal rate.

Example:

You earn ฿600,000 per year from other sources and ฿480,000 in rental income (฿40,000/month × 12). Your total taxable income is ฿1,080,000 before deductions.

Without deductions, you’d pay progressive tax on the total amount, with the highest portion taxed at 25%.

The 30% Standard Deduction for Rental Properties

Thailand allows property owners to deduct expenses from gross rental income before calculating tax. This matters.

You have two options:

Option 1: Claim actual expenses

Deduct real costs — repairs, maintenance, property management fees, condo fees, loan interest. You’ll need receipts and documentation for everything.

Option 2: Take the 30% standard deduction

Thailand allows a flat 30% deduction on gross rental income. No documentation required. Much simpler.

Most landlords take the standard deduction because it’s easier and often more favorable than tracking actual costs.

How it works:

Gross annual rent: ฿480,000 Standard deduction (30%): ฿144,000 Net taxable income from rent: ฿336,000

This net amount gets added to your other income and taxed at your marginal rate.

Withholding Tax: What Foreign Owners Need to Know

If you’re a foreign property owner (non-Thai national), there’s an additional layer: withholding tax.

When you sell or transfer property:

Thailand requires a 1% withholding tax on the appraised value (or sale price, whichever is higher) at the time of transfer. This is collected at the Land Office when ownership changes hands.

But for rental income, withholding tax typically doesn’t apply unless you’re renting through a property management company that withholds tax on your behalf.

Thai tax residents:

Personal income tax applies to worldwide income, though Thailand generally only enforces this on income remitted to Thailand. Rental income from Thai properties is taxable regardless of where you live.

Non-residents:

You’re taxed on Thai-source income, including rental income from properties in Thailand. The same progressive rates apply, but certain deductions available to residents don’t apply to you.

Foreign owners who don’t live in Thailand full-time should consult a Thai accountant or tax lawyer. Residency status determines your specific obligations.

Property Tax (Land and Building Tax)

Separate from income tax, Thailand has an annual property tax called the Land and Building Tax. This applies to property ownership, not rental income.

Rates for residential rental properties:

First ฿50 million of assessed value: 0.02%
Above ฿50 million: up to 0.1%

Example:

Condo assessed value: ฿5,000,000 Annual property tax: ฿5,000,000 × 0.02% = ฿1,000

This is separate from income tax. You pay it annually, usually through your condo building’s management.

Owner-occupied residential properties get more favorable rates. Rental properties don’t.

Condo Common Area Fees: Deductible or Not?

Condo common area fees (monthly maintenance paid to building management) are not deductible if you take the 30% standard deduction.

If you itemize actual expenses instead, you can deduct common area fees. But you’ll need to track and document all other expenses too.

For most landlords, the 30% standard deduction is more valuable, even if monthly condo fees run high.

Filing Requirements and Deadlines

You must report rental income on your annual personal income tax return.

Key deadlines:

Tax year: January 1 to December 31
Filing deadline: March 31 of the following year

How to file:

Complete the PND 90 or PND 91 form (personal income tax return)
Report gross rental income
Apply the 30% standard deduction (or itemize expenses)
Calculate tax based on total net income
Submit to the Revenue Department

You can file online through the Thai Revenue Department’s e-filing system or in person at a Revenue Department office.

If withholding tax was already paid:

Credit it against your final tax liability when you file. If withholding exceeded what you owe, you can request a refund. Refunds can take months.

What Happens If You Don’t Report Rental Income

Thailand takes tax compliance seriously. If you fail to report rental income, you risk:

Back taxes owed (with interest)
Penalties up to 100% of unpaid tax
Potential criminal charges for tax evasion (rare, but possible)

The Revenue Department can audit you going back multiple years. If you’ve been collecting rent without reporting it, the accumulated liability adds up fast.

Common mistake:

Foreign owners who don’t live in Thailand often assume they’re exempt from Thai tax on rental income. They’re not. Own property in Thailand and collect rent? You owe Thai income tax on that revenue, regardless of where you live.

How to Calculate Your Actual Tax Liability

Let’s walk through a full example.

Scenario:

You own a Bangkok condo that rents for ฿35,000/month (฿420,000/year). You have no other Thai income.

Step 1: Calculate net taxable income

Gross rent: ฿420,000 Standard deduction (30%): ฿126,000 Net rental income: ฿294,000

Step 2: Apply personal exemptions

Thailand allows a personal exemption of ฿60,000 for residents. Non-residents don’t get this, but if you’re a Thai tax resident:

Net rental income: ฿294,000 Personal exemption: ฿60,000 Taxable income: ฿234,000

Step 3: Calculate tax using progressive rates

First ฿150,000: 0% = ฿0
Next ฿84,000 (฿234,000 - ฿150,000): 5% = ฿4,200

Total tax owed: ฿4,200

Effective tax rate: roughly 1.4% of gross rent (or about 1.8% of net rent after the standard deduction).

Should You Hire a Tax Advisor?

Straightforward rental income from one or two condos? You can probably handle filing yourself or through basic accounting services.

Get professional help if:

You’re a foreign owner with complex residency status
You own multiple properties across different types (condo, house, commercial)
You’re itemizing expenses instead of taking the standard deduction
You’re earning other income in Thailand that puts you in a higher bracket
You have past unreported income and need to get compliant

Thai tax law gets complicated around residency and foreign ownership. A qualified accountant will help you structure things correctly and avoid costly mistakes.

The Bottom Line

Thailand taxes rental income as personal income using progressive rates. The 30% standard deduction cuts your taxable base significantly, keeping the effective tax rate reasonable for most landlords.

Collecting rent in Thailand? You’re required to report it and pay tax on it. The process isn’t complicated. Ignoring it is expensive.

Calculate your net rental income, understand your marginal tax rate, and file by March 31.
