Why monthly reporting matters
Foreign-invested Thai companies are required to keep books in Thai using TFRS, and mistakes accumulate quickly. Our bilingual monthly close gives management a clear view in English while ensuring every filing to the Revenue Department and DBD is compliant.
Tax planning for BOI groups
BOI-promoted entities enjoy tax holidays but often share expenses with non-BOI affiliates. Careful cost allocation prevents the Revenue Department from disallowing deductions during annual audits. We build BOI-safe transfer pricing files each year.
Frequently asked questions
Can you support BOI companies?
Yes. Our team files BOI Annual Reports, tracks tax privileges under Section 31/34, and reconciles imported machinery duty exemptions.
Do you file in English?
Filings to the Revenue Department are in Thai as required by law, but every management report and payslip is available in English or Chinese.
How do you handle e-Tax Invoice?
We enable e-Tax Invoice or e-Receipt on the RD portal, integrate it with Xero or Express, and sign each invoice with a CA-issued digital certificate.
Can you audit dormant companies?
Yes. Even a dormant Thai company must file an annual audit and DBD statements. We offer a discounted dormant-company package.
Do you cover cross-border WHT treaties?
Yes. We apply Thailand's double-tax treaties (typically reducing WHT from 15% to 5-10%) and prepare Form RO.22 for foreign investors.
