Accounting and tax for foreign-owned businesses operating in Thailand
A Thai-registered company keeps its books in Thai and in baht, files under the Revenue Code, and has its statements audited by a licensed CPA each year — regardless of who owns it. We work both directions: full compliance on the Thai side, and reporting your overseas head office can actually read.
International desk
Foreign-owned businesses in Thailand, handled in your own language
Prepare records to Thai requirements and agree the communication language before engagement. If a parent company needs English reporting or consolidation data, specify the format, reporting period and required adjustments when defining the scope.
Foreign-owned companies & FBL
Shareholding review under the Foreign Business Act, statements structured for an FBL application, and bank capital certification.
BOI-promoted operations
Segregate promoted (tax-exempt) income from ordinary income, report to promotion-certificate conditions, and prepare the annual BOI submission.
Expatriate personal tax
Check Thai tax residence using the 180-day calendar-year threshold, the appropriate PND.90/91 form, treaty conditions and the treatment of remitted foreign income.
Work permit ↔ accounting alignment
Reconcile capital, staffing, payroll and PND.1 records. Visa, work-permit and investment-promotion conditions can differ and must be checked for the application category.
Profit & dividend repatriation
10% dividend withholding, reduced treaty rates where available, and the documentation your bank requires for outbound transfers.
Transfer pricing with the parent
Disclosure Form and transfer-pricing documentation for groups above the revenue threshold, with defensible economic analysis.
Questions foreign-owned companies ask us
Any company registered in Thailand follows the Accounting Act B.E. 2543 and the financial reporting standards issued by TFAC; non-publicly accountable entities may apply TFRS for NPAEs. Books must be kept in Thai and in baht — records in another language require a Thai translation alongside.
Yes. The entity must appoint a qualified bookkeeper registered with the DBD, and a limited company's annual financial statements must be audited and opined on by a Thai licensed CPA every accounting period.
Promoted and non-promoted income and expenses must be segregated so exempt profit can be computed per the promotion certificate, and operating results must be reported to the BOI on the schedule set out in that certificate.
Spending 180 days or more in Thailand in a tax year makes you a Thai tax resident, taxable on Thai-source income and on foreign income brought into Thailand under Revenue Department rules. A double tax agreement may relieve the overlap.
The set filed with the DBD and Revenue Department must be in Thai, but we produce a parallel English set with reconciling workpapers so your parent company and its auditors can consolidate directly.
No. Documents move through our cloud workspace or by post, and every filing goes through RD e-Filing and the online social security portal, so we serve companies located in any Thai province.
