What is Real Estate Specific Business Tax in Thailand?
Fact-checked by a REMAX Thailand Real Estate Expert
The Definition
Specific Business Tax (SBT) is a 3.3% tax (3% base rate plus 10% local tax) levied on the higher of the sale price or appraised value when immovable property is sold in a commercial or profitable manner in Thailand. It applies to transfers of properties owned less than 5 years, unless exemptions apply, and is paid at the Land Department during title transfer. The seller is primarily liable, though it can be negotiated.
The Thai Legal Context
Governed by Chapter 5 of the Thai Revenue Code, SBT is administered by the Revenue Department and collected at the Department of Lands. Western buyers might expect property sales taxes to be based solely on capital gains, but Thailand treats short-term sales (under 5 years) as business activity, imposing a flat 3.3% regardless of profit. It applies equally to foreigners and Thais. However, Thais and permanent residents can register property as a primary residence in the blue house book (Thor.Ror.14) for potential exemption, while foreigners use the yellow book (Thor.Ror.13) and face stricter scrutiny.
Benefits & Risks
Advantages
- Encourages long-term holding (5+ years) by replacing the 3.3% SBT with a cheaper 0.5% stamp duty.
- Primary residence registration can exempt qualifying owners, rewarding genuine homeowners.
Risks & Disadvantages
- The high 3.3% rate is based on appraised value (not profit), hitting low-gain sales hard.
- Adds to layered taxes (e.g., withholding tax), significantly raising total seller transaction costs.
Showcase: How It Works
Let’s look at a real-world scenario to understand how Real Estate Specific Business Tax is applied during a property transaction.
The Scenario
- A seller flips a 6.4 million THB condo in Bangkok owned for 3 years.
- The property's appraised value is 6 million THB, so the higher sale price is used.
- Because it was owned for under 5 years, the 3.3% SBT applies instead of the 0.5% stamp duty.
The Result
Using the higher sale price of 6.4 million THB, the tax is calculated as 6,400,000 THB × 3.3%. This amount is paid by the seller at the Land Department alongside other transfer fees.
Outcome:Total SBT liability: 211,200 THB
Frequently Asked Questions
Who pays SBT in a property sale?
The seller is legally liable, but it is commonly negotiated. 50/50 splits are standard in buyer-favorable markets.
Does owning a property over 5 years always avoid SBT?
Yes, it usually shifts to a 0.5% stamp duty unless the Revenue Department deems the sale highly commercial (e.g., frequent flips).
Can foreigners claim SBT exemptions?
It is limited. Yellow house book registration does not grant full primary residence status like the Thai blue book, but holding the property for 5 years still exempts the owner from SBT.
Related Terms
Why It Matters
Ignoring SBT can inflate transaction costs by 3.3% of the property value, turning profitable sales into losses for short-term owners. Buyers and sellers must verify applicability upfront to negotiate effectively and avoid delays at the Land Office.
💡 REMAX Pro Tip
Always request the seller's Tabien Baan (house registration) 2 weeks pre-contract. If it's verified as a primary residence for over 1 year, push for a stamp duty exemption to save 2.8% compared to the SBT rate.
