Tax exemption up to 200,000 baht for solar rooftop systems
Thailand's Revenue Department has issued rules for a personal income tax exemption on expenses for purchasing and installing solar rooftop systems. Eligible individuals can deduct up to 200,000 baht for one system, provided the contract and grid connection occur between March 3, 2026, and December 31, 2028.
What this means for you
- Foreign residents in Thailand who are personal income taxpayers and own a residential house can deduct up to 200,000 baht for one solar rooftop system.
- The deduction applies only if the purchase and installation contract is signed and grid connection is approved between March 3, 2026, and December 31, 2028.
- You must obtain an e-tax invoice from the seller and be listed as the electricity account holder with the Metropolitan Electricity Authority or Provincial Electricity Authority.
