Tax on rental income in Thailand is a mandatory part of the calculations for any owner who plans to earn income from their property on Phuket. The Thai Revenue Code explicitly stipulates that income from leasing real estate is subject to taxation regardless of the lease term and the nationality of the owner.
The good news is that the actual tax burden is significantly lower than it seems at first glance. The system provides deductions, benefits for non-residents, and a progressive scale under which a small rental income is taxed at a minimal rate or not taxed at all. Concrete figures below will help understand the structure.
Income Tax in Thailand: Key Concepts
In the context of real estate, it is important to distinguish between two different taxes: corporate income tax and personal income tax. For most foreign owners of apartments and villas on Phuket, it is the Personal Income Tax (PIT) that is relevant.
The standard corporate income tax rate in Thailand is 20%. For small and medium-sized enterprises with a turnover of up to 30 million baht, reduced rates apply: profit up to 300,000 baht — 0%, from 300,001 to 3,000,000 baht — 15%, over 3,000,001 baht — 20%. These rates apply if the property is registered under a Thai company — one of the legal ownership structures for foreigners.
Tax on Rental Income: How It Is Calculated for Individuals
When renting out a condo or villa as an individual, the progressive Personal Income Tax scale applies. An important feature of the calculation is that the tax is levied not on the entire rental income, but only 70% of the received amount — 30% is automatically deducted as standard expenses, from which the tax-free allowance is additionally subtracted.
The current progressive personal income tax rates in Thailand:
| Annual Income (baht) | 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 5,000,001 | 35% |

Important Distinction: Resident or Non-Resident
The status of a Thai tax resident is determined by the number of days spent in the country. If the owner stays in Thailand for more than 180 days a year — they are considered a tax resident, can obtain a TAX ID, and pay tax according to the progressive scale above. With a small rental income, this is more advantageous than the fixed rate.
If a foreign non-resident does not live in Thailand for more than 180 days a year and does not have a TAX ID — a fixed Withholding Tax (advance tax withheld at source) of 15% of income applies. The management company or tenant withholds this tax upon payment and remits it to the tax authority — the owner receives income already net of tax, without needing to file a tax return themselves.
Tax on Condo in Thailand: Property Ownership Tax
In addition to the tax on rental income, Thailand has an annual property tax — the Land and Buildings Tax. For properties that the owner uses for personal residence and where they are registered in the house book (Tabien Baan), a substantial 90% discount applies — and in most cases, the tax turns out to be minimal.
For properties rented out or used for commercial purposes, the Land and Buildings Tax rates are higher. The specific amount depends on the appraised value of the property according to the Land Department — which is usually lower than the market value, reducing the overall tax burden.
Practical Calculation: How Much Does an Owner Actually Pay
Let’s consider a simplified example for a non-resident renting out an apartment worth 3 million baht with a 10% annual yield. Gross rental income — 300,000 baht per year. At the Withholding Tax rate of 15%, the tax would be 45,000 baht, net income — 255,000 baht. Effective tax burden — 15% of income, without the need to file a return.
For a resident with a TAX ID with the same income of 300,000 baht, after applying the 30% deduction, the taxable base would be 210,000 baht. Of this, the first 150,000 baht — 0%, the remaining 60,000 baht — 5%, total tax ~3,000 baht. This is significantly more profitable than the fixed 15% for non-residents with small amounts of income.
Taxes on Purchase and Sale of Real Estate in Thailand
In addition to annual taxes, one-time fees are paid in real estate transactions in Thailand. Their structure depends on the type of property, the period of ownership, and the seller’s status.
- Transfer Fee: 2% of the appraised value, usually split equally between buyer and seller.
- Stamp Duty: 0.5% — applies instead of Specific Business Tax when owning the property for more than 5 years.
- Specific Business Tax (SBT): 3.3% — upon sale of a property owned for less than 5 years, or if the seller is a company.
- Withholding Tax on sale: calculated on a progressive scale based on the appraised value and the period of ownership.
Frequently Asked Questions
Do I need to pay tax on rental income in Thailand if I am a non-resident?
Yes. The Thai Revenue Code requires tax to be paid on rental income regardless of the owner’s nationality. For non-residents, the standard Withholding Tax is 15% of income, which is withheld by the management company or tenant upon payment.
What is the income tax rate in Thailand for a foreign company?
The standard corporate tax rate is 20% of net profit. For SMEs with turnover up to 30 million baht, reduced rates apply: 0% up to 300,000 baht profit, 15% from 300,001 to 3,000,000 baht, 20% above.
What is more profitable: paying 15% as a non-resident or obtaining a TAX ID?
With a small rental income (up to 500,000 baht per year), obtaining a TAX ID and paying tax on a progressive scale is generally more profitable than the fixed 15%. With high income, the difference may be reversed. The decision depends on the specific amount of income.
How much is the annual tax on a condo in Thailand?
The Land and Buildings Tax for rental properties is calculated from the appraised value according to the Land Department — usually lower than the market value. For properties used for personal residence with registration in Tabien Baan, a 90% discount applies, and the tax in many cases tends to be close to zero.
Who pays the tax — the owner or the management company?
When working through a management company, the 15% Withholding Tax is withheld and remitted to the tax authority by the management company itself. The owner receives the net amount. If the property is rented out directly without a management company — the tax obligation falls on the owner, who must file a tax return and pay the tax themselves.
