Thailand Land and Building Tax: What Foreign Property Owners Actually Pay

One of the underappreciated costs of holding property in Thailand is the annual Land and Building Tax. It is not a large number for most foreign buyers compared to what they'd pay in the UK, Australia, or Singapore — but the difference between the standard rate and the residential exemption available to foreign owners is significant, and most buyers are not told about it until after they've already missed the registration that would have lowered their bill.

This post covers how the tax works, how it is calculated, and how foreign nationals can access the primary exemption.

The Legal Basis

Thailand replaced its old house and land tax system with the Land and Building Tax Act B.E. 2562 (2019), which came into full effect in the 2020-2021 assessment cycle and has been running through the current 2023-2026 cycle. The tax is levied annually by the local municipality (Amphur or Tessaban) based on the property's Treasury Department appraised value and its registered use classification.

The appraised value used for Land and Building Tax calculations is set by the Treasury Department and updated every four years. It is typically lower than actual market value — in some areas, significantly so. The tax base is this appraised value, not what you paid for the property.

Use Classification: This Is What Determines Your Rate

The Land and Building Tax uses tiered rates based on how the property is classified. The four primary classifications are:

Agricultural land: 0.01% to 0.10% (not relevant for most foreign buyers)

Residential property — primary residence: The most favourable rate. For a property registered as your primary domicile and where your name appears in the official house registration book, the first 10 million THB of appraised value on a condominium is entirely exempt. Only the value above that threshold is taxed, and only at 0.02%.

For landed residential property (not a condominium), the exemption is different: the first 50 million THB of combined land and structure appraised value is fully exempt. Again, only the excess above that figure is taxed at the minimal rate.

Residential property — second home, holiday property, or rental asset: Properties not registered as the owner's primary residence are taxed on a progressive scale starting at 0.02% (for appraised values up to 50 million THB) and scaling up to 0.10% for values between 50 and 75 million THB, and 0.15% for values over 75 million THB.

For a foreign-owned condominium in Bangkok priced around 5 million THB with an appraised value of approximately 3.5 million THB (typical appraisal-to-market discount), this translates to roughly 700 THB per year (about $20 USD) at the second-home rate. The tax is genuinely small at this end of the market.

Commercial or operational use: If the property is used for a commercial purpose — short-term daily or weekly rental, Airbnb-style operation, or any business activity — the rate starts at 0.30% of appraised value. For a property with a 5 million THB appraised value, this is 15,000 THB per year (~$430 USD).

Vacant or unimproved land: Land left entirely vacant is subject to a base rate of 0.30%, and this base rate escalates by 0.3 percentage points every three years of continued vacancy, up to a maximum of 3.0%. This punitive structure was designed to discourage land banking and idle real estate in Thailand.

The Yellow Tabien Baan: How Foreign Owners Access the Residential Exemption

The primary tax relief mechanism for foreign property owners is the Yellow Tabien Baan, officially called the Thor Ror 13. This is the house registration document specifically designated for non-Thai residents. When a foreign national's name is registered in the Yellow Tabien Baan at the property address, the property is classified as their primary residential domicile for tax purposes.

With this registration in place, the tax exemption on the first 10 million THB of appraised value for condominiums applies. For a typical foreign-owned condominium in Bangkok, Chiang Mai, or Phuket with an appraised value below 10 million THB, this means the annual Land and Building Tax is effectively zero.

The registration is done at the local Amphur (district office) with your passport, your condominium title deed (Or Chor 2), and in some districts, a completed application form. The process is not complicated, but it requires you to go in person.

Important: the Yellow Tabien Baan also has implications for tax residency under the Revenue Department's rules and for qualifying for the Specific Business Tax exemption when you eventually sell (more on that below). It is not purely a Land and Building Tax mechanism — consult your property lawyer about the broader implications before registering, particularly if you split time between Thailand and another country.

The Specific Business Tax Exemption Connection

If you sell your property within five years of purchase, the seller (you) is subject to a Specific Business Tax of 3.3% of the appraised value or sale price, whichever is higher. This is the primary anti-speculation tax in Thailand's property system.

There is an exemption: if the property was registered as your primary residence for at least one continuous year immediately preceding the sale — evidenced by the Yellow Tabien Baan — the SBT does not apply even if you are selling before the five-year threshold.

For a foreign owner who buys a condominium, plans to live in it, and might sell within five years due to a job change or relocation, registering the Yellow Tabien Baan early and maintaining it for 12 months before any anticipated sale can save the equivalent of 3.3% of the property value in tax.

Transfer Taxes at Point of Sale (Not Annual)

To be clear about what is and is not the annual Land and Building Tax: the taxes paid at the Land Office on transfer day are separate. They include:

• Transfer fee: 2% of the appraised value, conventionally split between buyer and seller though fully negotiable in the contract
• Specific Business Tax (SBT): 3.3% of the higher of appraised or sale price, paid by the seller if selling within five years without the primary residence exemption
• Stamp Duty: 0.5% (applies only if SBT is not triggered)
• Withholding Tax: A complex calculation based on the number of years of ownership, applied against the appraised value using a progressive income tax formula. The seller's burden and calculated separately for each transaction.

The Land and Building Tax is the ongoing annual holding cost, assessed by the municipality. It is distinct from the one-time transaction taxes above.

The 2026 Tax Residency Changes

A separate but related development for foreign nationals residing in Thailand: beginning January 1, 2024, the Revenue Department changed its interpretation of rules applying to tax residents (defined as those in Thailand for 180 days or more per calendar year). All foreign-sourced income remitted into Thailand — including funds used to pay property installments — is now taxable income for Thai tax residents.

A relief measure proposed for the 2026 tax year would exempt foreign-sourced income earned from 2024 onward if remitted within the same year it is earned or the immediately following year. Remittances outside this window may be taxed at progressive rates up to 35%.

If you are using offshore savings to fund property purchases while living in Thailand, the timing and structuring of your remittances now has direct tax implications. This intersects with — but is separate from — the Land and Building Tax.

The full picture of annual holding costs, transaction taxes at purchase and sale, and the interactions between residency status and your tax position in Thailand is covered in detail in the Buying Property in Thailand — Foreigner's Complete Toolkit, along with worked calculation examples and a checklist of the registration steps to access the residential tax exemption.

What This Means in Practice

For most foreign owners of a single condominium purchased as a primary or secondary residence, the annual Land and Building Tax is small — often negligible after the residential exemption. The more significant tax consideration in Thai property is the transaction tax structure at the point of sale, where the SBT and withholding tax calculations can materially affect your net proceeds.

The practical steps for foreign buyers:

1. Register the Yellow Tabien Baan at your local Amphur after completing the title transfer — it locks in the residential classification and the primary-residence exemption on Land and Building Tax
2. Maintain the registration for at least 12 months before any anticipated sale within the five-year SBT window
3. Keep the annual tax assessment notice from the municipality to track when payments are due (typically payable by April 30 of the relevant year)
4. If the property is used for short-term rental, register it correctly as commercial use — misclassifying a commercial rental as residential creates liability for back taxes and penalties
