Thai tax rules change often, and errors are expensive
Thailand taxes companies at a standard corporate rate of 20%, applies 7% VAT and uses withholding tax on many payments, including payments abroad. Rules on foreign income, transfer pricing and tax treaties have tightened in recent years, and penalties and surcharges add up quickly.
We look at your situation as a whole (company, shareholders and people) and give you written advice you can act on.

Frequently asked questions
When does a company have to register for VAT in Thailand?
When its taxable turnover exceeds THB 1.8 million a year, within 30 days of reaching that threshold. Some businesses register voluntarily earlier.
Does my Thai company need transfer pricing documentation?
Companies with revenue of THB 200 million or more must file a transfer pricing disclosure form with their annual tax return, and may be asked for full documentation. Smaller groups still need arm's length prices on related-party transactions.
Can you handle a Revenue Department audit?
Yes. We review the case, prepare the answers and documents, and represent you in the discussions with the tax officers.
