The Definition
In Thailand, the Treasury Floor Value refers to the official land appraisal value set by the Treasury Department, serving as the minimum assessed value for properties updated every 4 years. It acts as a floor because taxes like transfer fees, Specific Business Tax (SBT), and stamp duty are computed from the higher of this appraised value or the registered sale price.
The Treasury Department conducts appraisals every 4 years, while the Land Department assesses buildings and enforces transfers under Land Code Section 104, mandating true market value disclosure. The Revenue Department uses this baseline for taxes like SBT (3.3%), withholding tax (1%), transfer fees (2%), and stamp duty (0.5%). While the floor applies identically to foreigners and Thais, foreigners remitting funds must navigate extra Anti-Money Laundering Office (AMLO) scrutiny if bank transfers significantly exceed this typically undervalued floor.
Let’s look at a real-world scenario to understand how Treasury Floor Value is applied during a property transaction.
The transfer fee (2%), SBT (3.3%), and stamp duty (0.5%) are computed using the higher registered market value over the 1.2M THB floor.
Access the Treasury Department website or Land Office portal by entering the province, tambon, and plot details.
No, the registered value cannot go below it, and must reflect true market price to avoid Land Code violations.
Yes, it covers both land and structures, adjusted appropriately by the Land Department.
Ignoring the Treasury Floor Value can lead to rejected titles, massive fines, or AMLO freezes on foreign funds. Align declarations with market reality against this low floor to safeguard investments.
Always verify the latest Treasury Floor Value via the official app or Land Office portal before offers, then budget taxes on the higher of floor or sale price.
