Emerhub keeps your Thai company compliant with the Revenue Department: monthly withholding and VAT filings, bookkeeping, audited financial statements, and the annual return, all handled by a local team in Bangkok. Clean books and on-time filings, without building a finance department.
Thailand isn't a once-a-year filing. Withholding and VAT returns are due every month, and most foreign companies find the ongoing workload, not the tax itself, is the hard part to keep up with.
Running Thai accounting yourself means monthly withholding returns (PND 1, 3, and 53), the monthly VAT return, and social security, plus the half-year and annual corporate returns, each with the Revenue Department on a strict calendar.
Every payment to a supplier or employee may carry withholding, and each one needs the right form and a certificate issued. A missed filing means a 1.5% monthly surcharge and penalties.
A Bangkok accounting team handles every monthly, half-year, and annual filing with the Revenue Department, keeps your books to Thai accounting standards (TFRS), and classifies and issues withholding correctly.
You get clean, audit-ready books and on-time filings every month, without hiring in Bangkok, and someone to handle the audit if it comes.

What companies ask most often before handing over their books in Thailand.
Monthly withholding and VAT filings, bookkeeping, financial statements and audit coordination, the half-year and annual corporate returns, and tax advisory. We can run your entire Thai finance function, or just the parts you need. The scope and monthly fee are set during onboarding, once we've seen your transaction volume and structure.
Monthly. Withholding returns (PND 1, 3, and 53) are due by the 7th of the following month, and the VAT return (PP 30) by the 15th, with e-filing extensions of about a week on each. On top of that, corporations file a half-year return (PND 51) and an annual return (PND 50) within 150 days of the fiscal year-end. We handle the full cycle.
VAT is currently 7%, reduced from the statutory rate of 10%. The reduction has been extended repeatedly and is in place through 30 September 2026, subject to further extension. Registration is required once turnover passes 1.8 million baht a year, and returns are filed monthly. We handle registration and the monthly PP 30 filings.
When your company pays for services, salaries, rent, and many other items, it must withhold a percentage, remit it to the Revenue Department, and issue a withholding certificate to the payee. The rate and form depend on the payment type and whether the recipient is an individual or a company. Getting the classification right each month is the most common compliance pitfall, and it's a core part of what we manage.
Yes. Every Thai limited company must have its annual financial statements audited by a licensed Thai auditor and filed with the Revenue Department and the Department of Business Development (DBD), regardless of size or activity. We keep your books to audit-ready standard through the year and coordinate the audit so the filing is straightforward.
The standard corporate income tax rate is 20%. Qualifying SMEs, with paid-up capital up to 5 million baht and annual revenue up to 30 million baht, pay progressive rates: 0% on the first 300,000 baht of net profit, 15% on the next band up to 3 million, and 20% above that. We confirm what applies to your company and build it into your filings.
