These determine whether Specific Business Tax or stamp duty applies, and how withholding tax is calculated.

Agent Commission

No fixed law sets this — 3% of the sale price is the most common market convention in Thailand, typically paid by the seller.

Who actually pays what is negotiable and varies by contract — the split above reflects common market convention, not a legal requirement. SBT/stamp duty and withholding tax are technically the seller's tax obligations; agent commission is customarily paid by the seller; the 2% transfer fee is most commonly split 50/50 between buyer and seller.

Estimates only, for planning purposes — not tax, legal or financial advice. Standard rates: transfer fee 2%, Specific Business Tax 3.3% (properties held under 5 years), stamp duty 0.5% (properties held 5+ years — SBT and stamp duty are not both charged), withholding tax 1% flat for juristic sellers or a progressive calculation for individual sellers based on years owned and the Revenue Department's PIT brackets. A temporary transfer-fee reduction (2% to 0.01%) applied to homes/condos up to ฿7 million for Thai national buyers from 22 April 2025 to 30 June 2026 and is not reflected in this calculator's default 2% rate — that promotion window has closed as of this writing and did not extend to foreign buyers in the first place. Exemptions (inherited property, primary residences held as such, BOI-promoted structures and others) can change these figures significantly. Confirm exact numbers with the Land Office and a Thai accountant before any transaction. BAANLYY and One Life Ventures Co., Ltd. are not tax advisors.

01

The four costs this calculator covers

Thai property transfers can involve up to four separate charges: the transfer fee (2% of the Land Department's appraised value or the contract price, whichever is higher — a flat registration fee regardless of seller status); either Specific Business Tax (3.3%, if the seller has owned the property under 5 years) or stamp duty (0.5%, if owned 5 years or more — never both on the same transaction); and withholding tax, which is a flat 1% for a juristic (company) seller but a genuinely complex progressive calculation for an individual seller based on years owned and Thailand's personal income tax brackets. Agent commission, commonly around 3%, is a separate market-convention cost, not a government fee.

02

Why the seller's ownership period matters so much

Two of the four costs above swing directly on how long the seller has owned the property. Under 5 years triggers the higher 3.3% Specific Business Tax instead of the lower 0.5% stamp duty — a meaningful difference on a multi-million-baht property. And for an individual seller, the withholding-tax deduction table is far more generous to longer ownership (92% deduction at 1 year owned, falling to 50% at 8+ years), which — combined with the progressive tax-rate mechanics — usually means a proportionally lower withholding tax the longer the property has been held. Toggle the "years owned" field in the calculator above to see both effects at once.

A note on the 2025–2026 transfer-fee reduction

Thailand ran a temporary transfer-fee reduction — from the standard 2% down to just 0.01% — for homes and condos valued up to ฿7 million, effective 22 April 2025 through 30 June 2026. That window has now closed as of this writing, and even while it was active, it applied to Thai national buyers only, not foreign buyers. This calculator uses the standard 2% rate throughout for that reason; always check the Land Department directly for any current promotion before assuming a reduced rate applies to your transaction.

Frequently asked

What are the main government costs to transfer property in Thailand?Four possible charges: a 2% transfer fee (Land Department, on the higher of appraised or contract value), Specific Business Tax at 3.3% if the seller has owned the property under 5 years, stamp duty at 0.5% instead of SBT if owned 5+ years (SBT and stamp duty are never both charged on the same transfer), and withholding tax — a flat 1% for a juristic (company) seller, or a progressive calculation based on years owned and the Revenue Department's personal income tax brackets for an individual seller. Combined, these typically run 2.5% to over 6% of the appraised value depending on the seller's holding period and status.
Is the 0.01% reduced transfer fee still available in 2026?That temporary reduction (from the standard 2% down to 0.01%) applied to homes and condos valued up to ฿7 million, and ran from 22 April 2025 to 30 June 2026 — a window that has now closed as of this writing (July 2026). It also only ever applied to Thai national buyers, not foreigners. This calculator defaults to the standard 2% rate; always confirm current promotions directly with the Land Department before assuming a reduced rate applies.
How is withholding tax calculated for an individual seller?The Land Office applies a deduction (ranging from 92% for 1 year owned down to 50% for 8+ years owned) to the appraised value, divides the remainder by the number of years owned (capped at 10), applies Thailand's progressive personal income tax rates (0–35%) to that annual figure, then multiplies the result by the number of years owned. It is more favourable to longer-held properties per year of ownership, but the calculation is genuinely complex — this calculator automates the standard method, but always have a Thai accountant confirm the exact figure.
Who normally pays each cost — buyer or seller?It's negotiable and set by contract, not law, but common market convention in Thailand is: the 2% transfer fee is often split 50/50 between buyer and seller; Specific Business Tax or stamp duty and withholding tax are technically the seller's tax obligations and customarily paid by the seller; agent commission (commonly around 3%) is also customarily paid by the seller. None of this is fixed — negotiate and document the agreed split in the sale and purchase agreement.
Does this calculator account for exemptions?No — it shows the standard-case calculation. Real exemptions and reductions exist (inherited property, a seller's registered primary residence held for the required period, BOI-promoted structures, and others) that can significantly reduce SBT or withholding tax. This tool is a planning estimate, not a substitute for a Land Office or Thai accountant confirming your specific transaction's actual liability.
