Thailand has no general net-wealth tax and no gift or estate tax on most transfers below significant thresholds. Instead, Thailand levies an inheritance tax on inheritances exceeding THB 100 million per beneficiary (10% rate generally, 5% for direct ascendants/descendants), and a land and building tax (an annual property-holding tax, not a wealth tax on total net worth) assessed on the appraised value of land and buildings. Proposals for a broader wealth tax have been discussed periodically by Thai policymakers but none had been enacted as of mid-2026.
Foreign residents with significant assets should understand that Thailand's tax burden on holding wealth is comparatively light versus many Western countries — there is no annual net-worth tax — but inheritance and property-holding taxes still apply and matter for estate planning.
Key Facts
No general net-wealth tax on individuals' total assets exists in Thailand.
Inheritance tax applies only to the portion of inheritance exceeding THB 100 million per beneficiary: 5% for ascendants/descendants (parents, children), 10% for others.
Gifts between parents and children, or between spouses, are exempt up to THB 20 million per year; gifts to others are exempt up to THB 10 million per year, with tax above those thresholds at 5%.
The annual Land and Building Tax (not a wealth tax per se) taxes the appraised value of real estate holdings at rates from 0.01% to 0.7% depending on use (agricultural, residential, commercial/other).
No wealth tax has been enacted in Thailand as of mid-2026 despite periodic policy discussion.
