Thai Corporate Compliance: The Annual Filing Checklist for Foreign-Owned Companies

Audited accounts, corporate income tax, VAT, social security, and shareholder meetings — the recurring obligations that catch new operators off guard. None of these pause because the company is foreign-owned, dormant, or still ramping up.

The annual cycle, in order

Monthly VAT (by the 15th if registered), monthly withholding tax, monthly social security, annual financial statements and audit, corporate income tax within 150 days of fiscal year-end, and an annual shareholder meeting within four months of year-end. Each deadline has a penalty. None of them wait for the accountant to chase you.

Why foreign directors miss this

Local bookkeepers typically file what they are given. They do not always track overseas shareholder signatures, auditor–DBD coordination, or the fact that a dormant year still requires an audit and a meeting. The gap is accountability, not a missing form.

What you still have to provide

Bank statements, sales and expense records, and directors or shareholders available to sign. Everything else — chasing the auditor, minutes, Revenue Department filings, confirmation receipts — can be coordinated as one workstream.

Dormant is not exempt

No revenue does not mean no filings. A company that exists has statutory duties. If you are winding down, that is a separate process. If you are pausing, keep the compliance calendar running.

Common questions

Is this the same as bookkeeping?
No. Bookkeeping produces the numbers. Compliance coordination makes sure audit, tax, social security, and meetings actually happen on time, with one person accountable for the cycle.
What is the first deadline after incorporation?
It depends on VAT registration, payroll, and your fiscal year. We map the first twelve months at setup so the first surprise is not a penalty notice.
Can our home-country accountant handle this?
They can contribute numbers. Thai statutory filings still need a Thai auditor and local process knowledge. Treat overseas finance as an input, not the owner of the Thai cycle.
