Moving to Thailand opens up new opportunities for many foreigners, whether it’s buying property, starting a business, or working under contract. An important aspect of life in a new country is its tax system, especially if you plan on long-term residence, property ownership, or commercial activity. Understanding the tax structure will help you avoid unpleasant surprises and manage your finances wisely. This article provides a detailed overview of the key taxes foreigners encounter in Thailand.
1. Taxes on Real Estate in Thailand
Important changes to Thai tax legislation were introduced in 2020. It is crucial to be aware of these for anyone acquiring (or planning to acquire) property or land in the Kingdom.
Tax liabilities differ depending on the ownership structure—leasehold (long-term lease) or freehold (full ownership). Let’s examine the main types of property taxes:
| Tax Type | Rate | Paid By | Description |
|---|---|---|---|
| Property Transfer Fee | 2% | Buyer/Seller (shared) | Paid upon the legal transfer of ownership rights at the Land Department (Freehold). |
| Leasehold Registration Fee | 1% | Buyer/Seller (shared) | For registering a long-term lease agreement at the Land Department. |
| Stamp Duty | 0.1% – 0.5% | Seller | 0.1% for leasehold, 0.5% for freehold (if Specific Business Tax is not applicable). |
| Specific Business Tax (SBT) | 3.3% | Seller | Applies if the seller is a company or an individual selling property held for less than 5 years. |
| Withholding Tax (on sale) | Progressive / 1% | Buyer (withheld from seller) | Calculated on an estimated personal income tax scale for individuals, or a flat 1% for corporate sellers. |
1.1. Taxes When Buying Property
When purchasing property, foreigners must account for the Transfer Fee and Stamp Duty. For example, the transfer fee for freehold is 2% of the official appraised value, while for leasehold registration it is 1%. These fees are typically split 50/50 between buyer and seller by mutual agreement, but the buyer is responsible for settling their share upon registration.
1.2. Taxes on Property Ownership (Annual Property Tax)
Taxes on owning property depend on whether it’s used for personal residence or rental/commercial purposes. The annual Land and Building Tax rates vary based on the property’s officially appraised value and its use.
| Property Category | Approximate Tax Rate |
|---|---|
| Owner-occupied primary residence (appraised value ≤ 50M THB) | 0% (Exempt) |
| Secondary residential property / Primary residence (value > 50M THB) | 0.02% – 0.10% (progressive) |
| Agricultural Land | 0.01% – 0.10% |
| Commercial / Industrial Land & Buildings | 0.30% – 0.70% |
1.3. Taxes When Selling Property
When selling property, the seller faces several potential taxes:
- Transfer Fee & Stamp Duty: As outlined in the overview table.
- Specific Business Tax (SBT): A 3.3% tax applies if the property is sold within 5 years of acquisition.
- Withholding Tax: The buyer is legally required to withhold tax from the transaction payment. For individual sellers, this is calculated using a progressive tax scale based on government appraisal and years of ownership. For corporate sellers, a flat 1% withholding rate applies.
1.4. Taxes on Rental Income
Foreigners renting out property in Thailand are required to pay income tax on their rental earnings:
- Tax Residents: Rental income is added to total taxable income and taxed under the progressive Personal Income Tax scale (5%–35%). Tax residents are allowed to claim standard expense deductions.
- Non-Residents: Rental income earned by non-residents is subject to a flat 15% withholding tax on gross rental payments, typically remitted by the management company or tenant.
