Direct answer
Withholding tax on some Thai property sales is a Revenue Department topic that depends on the seller’s status, the tax base used for the transaction, and current statutory schedules. The approved source set for this article does not include a page that publishes a complete property-sale withholding rate table, so this guide explains the confirmation process and provides only a clearly labeled hypothetical example. Confirm the calculation with the Revenue Department and counsel before transfer.
Key takeaways
- 1.Do not copy withholding percentages from unofficial blogs.
- 2.Seller type and tax base drive the correct schedule—ask counsel.
- 3.Withholding often interacts with other transfer charges settled around Land Office registration.
- 4.Hypothetical math below is illustrative only.
- 5.Needs Thai tax review before transactional reliance.
Important terms
Withholding tax — Tax collected at source on certain payments or registrations, credited or applied under income-tax rules as advised by a tax professional.
Tax base — The amount to which a rate is applied (for example official appraisal vs contract price)—the correct base is a legal question.
SBT — Separate specific-business-tax regime for certain immovable-property sales. (rd-sbt; rd-section-91)
Detailed answer: confirm before you calculate
This site’s approved source list for the present article includes Revenue Department materials on SBT and Section 91, and the Department of Lands homepage, but not a complete official English withholding schedule for every property-sale scenario. Therefore:
- Identify seller type (individual, company, other).
- Ask counsel which withholding rule applies on those facts.
- Confirm the tax base the Land Office / Revenue officers will use.
- Obtain a written estimate before transfer day. (dol-home)
- Keep receipts for filing and SPA reimbursement claims.
Do not treat SBT’s published 0.1% real-estate table rate as a withholding-tax rate—they are different concepts. (rd-sbt)
Step-by-step
- Send SPA draft and seller profile to a Thai tax-capable adviser.
- Request the official computation worksheet used at transfer.
- Cross-check whether SBT under Royal Decree categories also applies (separate analysis).
- Align SPA language on who funds the withholding economically.
- Pay and archive the official receipt.
Comparison table
| Item | Safe approach | Unsafe approach |
|---|---|---|
| Rate | Confirm with Revenue Department / counsel | Copy a blog percentage |
| Base | Ask which value officers will use | Assume contract price always |
| Interaction with SBT | Analyse separately | Blend rates into one invented number |
Hypothetical example
HYPOTHETICAL example with assumed rates — confirm with Revenue Department / counsel. Not an official computation.
- Assumed tax base: 4,000,000 THB
- Assumed withholding rate for this illustration: 1% (assumed only)
- Assumed withholding: 4,000,000 x 0.01 = 40,000 THB
This shows the multiplication pattern only. Your real rate, base, and exemptions may differ—or withholding may be computed on a progressive schedule for some sellers.
Risks
- Under-withholding blocking transfer.
- Over-reliance on outdated personal experience from a prior deal.
- Ignoring corporate vs individual seller differences.
- Confusing SBT with income withholding.
Checklist
- Seller profile documented
- Counsel/tax adviser confirms applicable rule
- Official estimate obtained
- SPA states economic bearer of withholding
- Receipt retained
FAQ
Why will this page not state “the” withholding rate?
Because a complete approved-source rate table for all property-sale withholdings is not in the cited set for this article. Inventing one would violate the site’s source rules.
Is withholding the same as SBT?
No. SBT is a distinct regime described in Revenue Department SBT materials.
When is it usually paid?
Often in connection with registration formalities—confirm local practice with counsel and the Land Office.
