Annual Property Tax in Thailand: Rates, Calculations, and What Foreign Owners Pay in 2026
Thailand introduced a full annual land and buildings tax in 2020, ending decades of near-zero property holding costs. For foreign condominium owners and expat investors, the shift raised an obvious question: how much does owning property here actually cost each year? The short answer is: still very little compared to most of Asia, but the category of use matters enormously.
This article breaks down the exact rates, realistic payment scenarios, and the most common mistakes foreign buyers make when calculating their annual tax bill in 2026.
Quick Answer
- The Land and Building Tax Act (B.E. 2562) has been in force since 2020. Tax is assessed annually on the Treasury Department appraised value of land and/or buildings - not the market purchase price.
- For a primary residence with the owner registered in the household registration book (tabien baan), the first 50 million baht of appraised value is fully exempt.
- For residential property that is not a primary residence, the rate starts at 0.02% on values up to 50 million baht.
- Commercial and rental property is taxed at 0.3% to 0.7% depending on appraised value.
- Vacant land is taxed progressively, starting at 0.3% and rising every three years to a ceiling of 3%.
- Payment is due to the local authority (Tessaban or OrBorTor) by end of April each year.
- From 2026, full statutory rates are expected to apply without the discount relief that was in place from 2020 to 2025.
Scenarios and Options
Scenario 1 - Condominium for Personal Use
A foreign buyer holds a freehold condo appraised at 8 million baht by the Treasury Department. If the owner is registered in the tabien baan as a primary resident, the first 50 million baht is exempt, resulting in a tax bill of 0 baht per year.
In practice, most foreigners cannot register in the household book without a Thai ID card or permanent residence permit. Without tabien baan registration, the unit is treated as a secondary residence, and the 0.02% rate applies. On 8 million baht, that equals 1,600 baht per year (approximately 45 USD). Still negligible by any international standard.
Scenario 2 - Condominium Used for Rental Income
A unit appraised at 12 million baht is placed with a property management company and rented out short- or long-term. This use is classified as commercial. The applicable rate is 0.3%.
Calculation: 12,000,000 x 0.003 = 36,000 baht per year (approximately 1,000 USD). This is a meaningful holding cost and should be factored into net yield projections.
Scenario 3 - Villa Held Through a Thai Company
A Thai-registered company holds land and a villa with a combined appraised value of 25 million baht, rented to guests. The commercial rate of 0.3% applies to the total appraised value.
Tax: 25,000,000 x 0.003 = 75,000 baht per year. The liability falls on the legal owner (the company), not the tenant or nominee director.
Scenario 4 - Vacant Land Held Speculatively
A plot appraised at 10 million baht sits undeveloped. In year one, the rate is 0.3%, giving a tax bill of 30,000 baht. If the land remains unused, the rate increases by 0.3 percentage points every three years, eventually reaching the statutory cap of 3% - equivalent to 300,000 baht per year on the same plot. This escalating structure is a deliberate government policy to discourage land banking.
Comparison Table: Tax Rates by Use Category
| Parameter | Primary Residence (with tabien baan) | Secondary Residence / No tabien baan | Commercial or Rental Use | Vacant Land |
|---|---|---|---|---|
| Rate up to 50M baht | 0% (exempt) then 0.02% | 0.02% | 0.3% | 0.3% (escalating) |
| Rate 50M - 75M baht | 0.03% | 0.03% | 0.4% | 0.4% |
| Rate 75M - 100M baht | 0.05% | 0.05% | 0.5% | 0.5% |
| Rate above 100M baht | 0.1% | 0.1% | 0.7% | up to 3% |
| Example: 10M baht asset | 0 baht | 2,000 baht | 30,000 baht | 30,000 baht (rising) |
| Payment deadline | April | April | April | April |
| Who pays | Registered owner | Registered owner | Registered owner | Registered owner |
Rates are based on the Land and Building Tax Act B.E. 2562. Discount relief of 90% applied from 2020 to 2023, reduced discounts applied in 2024-2025. Full rates are expected from 2026 onward, subject to any cabinet extension.
How Appraised Value Is Determined
The Treasury Department sets the official appraised value used as the tax base. Revaluations occur every four years. The current cycle runs from 2023 to 2026.
For condominiums, the appraised value is typically 30% to 50% below the market purchase price. A unit bought for 10 million baht may carry a Treasury valuation of 5 to 7 million baht, directly reducing the tax base. For land in high-demand locations - Bang Tao, Laguna, and Rawai in Phuket, or Sukhumvit and Silom in Bangkok - appraised values are closer to market rates. Owners can check the current valuation at pvd.treasury.go.th.
How to Pay: A Practical Checklist
- Receive your tax notice from the local authority (typically issued in February or March)
- Verify the use category and appraised value stated in the notice
- If you dispute the valuation, submit an objection within 30 days of receiving the notice
- Pay by end of April via bank transfer, in person at the municipal office, or through the municipality's payment app
- Retain the payment receipt - it will be required documentation when selling the property
Main Risks and Mistakes
1. Misclassifying rental use. If you rent your condo through Airbnb or any platform, the local authority can reclassify the unit as commercial. The rate jumps from 0.02% to 0.3% - a 15x increase. Ensure your declared use category matches actual use.
2. Missing tax notices while abroad. Municipalities send notices in February and March. If the owner is overseas and notices go unread, a penalty of 1% per month accrues on the unpaid amount. Appoint a local contact or property manager to monitor correspondence.
3. Assuming the primary residence exemption applies. The 50 million baht exemption requires tabien baan registration. Most foreigners - including long-term expats on retirement or work visas - cannot access this. Budget for the 0.02% secondary residence rate as your baseline.
4. Forgetting about vacant land held in a company. Undeveloped land owned by a Thai company triggers the escalating vacant-land rate. What starts as a manageable cost can become a significant liability within six to nine years of non-development.
5. Conflating property tax with rental income tax. The annual land and buildings tax is a local-authority levy. Tax on rental income is a separate national-level obligation paid to the Revenue Department. Neither offsets the other, and both apply simultaneously if you earn rental income.
FAQ
Do foreigners pay higher rates than Thai nationals? No. The Land and Building Tax Act does not distinguish between Thai citizens and foreign nationals, residents and non-residents. The rate depends solely on use category and appraised value.
Is there a minimum value before tax is charged? For primary residences with tabien baan, the first 50 million baht is fully exempt. For all other categories, tax is calculated from the first baht of appraised value with no minimum threshold.
Do I pay annual tax on an off-plan purchase? No. The annual tax is assessed only after ownership is registered with the Land Department and a Chanote title deed is issued in your name. Pre-transfer, no annual property tax applies.
Does a double tax treaty (DTT) cover this property tax? No. DTTs typically cover income taxes. The Thailand land and buildings tax is a property holding tax and cannot be offset against income tax liabilities in your home country.
What happens if I don't pay? A penalty of 1% per month applies to unpaid amounts. Prolonged non-payment can result in the local authority placing a lien on the property, though enforcement against foreign condo owners has been rare in practice.
How does the annual tax relate to one-time transfer fees? They are entirely separate. At purchase, you pay a transfer fee (2% of appraised value) and potentially stamp duty (0.5%). The annual property tax is an ongoing holding cost unrelated to the transaction.
Can I deduct the annual property tax from rental income for Thai tax purposes? Yes. When filing a Thai personal income tax return (PND 90 or PND 91), the annual land and buildings tax paid on a rental property can be included as a deductible expense, reducing your net taxable rental income.
Will the tax discount continue in 2026? The government applied a 90% discount in 2020 to 2023 and reduced discounts through 2025. Market consensus is that full statutory rates apply from 2026 onward, though the cabinet retains the authority to extend relief. Budget for full rates to be conservative.
For a typical Phuket condominium valued between 5 and 15 million baht, the annual tax bill ranges from roughly 1,000 to 45,000 baht depending on how the unit is used - a minor line item for most individual investors. For a portfolio of properties or a villa with land, the cumulative figure becomes material and belongs in any serious net yield calculation.
