Thailand real estate terms G
Letter G covers government assessment value and developer guarantee periods. Both appear in due diligence reports, Land Office transfer worksheets, and off-plan sale contracts. Foreign buyers in Bangkok, Phuket, and Chiang Mai encounter these terms when calculating taxes and reviewing new-build warranties.

Terms starting with G
Government assessment value
The Land Office maintains a government appraisal schedule updated periodically by the Revenue Department. This assessed value is the basis for withholding tax calculations when an individual Thai seller transfers property. It is not necessarily the price you pay the developer or resale owner.
At transfer, the Department of Lands compares three figures: government assessment value, registered sale price, and actual market consideration. Under-declaring registered value to reduce the 2% transfer fee triggers Revenue Department scrutiny. Your lawyer prepares a tax worksheet before registration day.
Guarantee period
Developers of new condominiums and house projects typically warrant structural defects for one to five years after handover. The guarantee period must appear in the sale and purchase agreement in Thai and English. Fit-out, appliances, and common-area finishes may carry shorter warranties.
Foreign off-plan buyers should inspect the unit before final payment, document defects in writing, and confirm the juristic person will coordinate repairs. Guarantee claims after handover require following notification timelines in the SPA. See our letter O glossary page for off-plan purchase context.
How assessment value affects transfer tax
Expats often focus on negotiated price but Land Office registration involves multiple valuation bases. The table below shows how each figure is used in a typical Bangkok condo resale.
| Value type | Typical use at transfer |
|---|---|
| Government assessment | Withholding tax brackets for individual sellers and stamp duty calculations. |
| Registered sale price | Transfer fee at 2% and specific business tax when applicable. |
| Market price | What buyer and seller actually agree; must not be understated at Land Office. |
Guarantee period checklist for expat buyers
Before signing an off-plan SPA or accepting handover on a new build, verify these points with independent counsel. Developer sales teams optimise for closing. Your lawyer verifies whether warranty language is enforceable.
- Structural warranty duration stated in Thai and English sale and purchase agreement
- Defect notification procedure and developer response timeline
- Whether common-area defects fall under juristic person or developer responsibility
- Penalty clause if developer fails to remedy within guarantee window
- Handover inspection report signed before final payment tranche
Legal context for foreign buyers
Government assessment value and guarantee periods sit at the intersection of tax law and contract law. Foreign condominium buyers remit funds from abroad and register freehold title at Land Office. Tax worksheets use official appraisal schedules regardless of nationality. Developer guarantees bind the seller entity named in the SPA, not the marketing brand.
If you purchase leasehold villa property instead of condo freehold, guarantee and tax rules differ. Lease registration and superficies structures are covered in our letter L and letter S glossary pages.
Common mistakes foreigners make
- Assuming the sale price alone determines all transfer taxes. Withholding tax for individual sellers uses government assessment value brackets.
- Accepting a verbal guarantee period from sales staff without written SPA clause in both languages.
- Under-declaring registered value to save transfer fee. Revenue Department can reassess and impose penalties.
- Skipping handover inspection because the unit looks finished. Latent structural defects discovered after guarantee expiry are costly.
- Confusing developer marketing warranty with statutory guarantee under Thai contract law.
Frequently asked questions
General answers for expats reading letter G terms in sale contracts and Land Office forms. This is orientation, not tax or legal advice for your specific transaction.
Q:What is government assessment value in Thailand?
It is the official appraisal value the Land Office and Revenue Department use for certain tax calculations. It is updated periodically and may differ from the price you negotiate with the seller. Your lawyer compares assessment value, registered value, and market price before transfer day.
Q:Does assessment value affect my transfer fee as a buyer?
Transfer fee at 2% is calculated on registered value declared at Land Office, not directly on assessment value. However, all three figures appear in due diligence and Revenue Department may challenge under-declared registered value.
Q:How long is a developer guarantee period?
New condominium and house projects typically offer one to five years for structural defects. Fit-out and appliance warranties may be shorter. Verify exact duration, scope, and claim procedure in the sale and purchase agreement before paying off-plan deposits.
Q:Can I claim guarantee repairs after handover?
Yes, if defects fall within the written guarantee scope and you follow notification timelines in the SPA. Document defects with photos and written notice to developer and juristic person. Keep copies for dispute resolution.
Q:Where do I see assessment value before buying?
Your property lawyer requests the current government appraisal from Land Office during title search. It appears on transfer calculation worksheets prepared for registration day.
Q:Is guarantee period the same as latent defect liability?
Contractual guarantee is what the developer promises in the SPA. Statutory latent defect rules under the Civil and Commercial Code may provide additional remedies in some cases. A licensed lawyer explains how both apply to your purchase.
Q:Do resale condos include developer guarantee?
Original developer guarantee may still apply if within the period and transferable to subsequent owners. Resale purchases need written confirmation of remaining warranty and any prior claims. Second-hand units often rely on buyer inspection instead.
