Dormant company in Thailand: what still has to be filed?
Everything annual: audited financial statements to the DBD after an AGM, the PND 50 tax return, the PND 51 half-year estimate, and the บอจ.5 shareholder list, plus every monthly return the company is still registered for, VAT above all. Dormant means the business stopped; the obligations only stop when the company is formally dissolved and its liquidation completed.

The annual set, which never switches off
- The audit. Zero revenue does not exempt you; it just makes the audit cheap, roughly 4,000 to 7,000 baht at published rates.
- The AGM, within 4 months of year end, to approve the audited statements, and the บอจ.5 shareholder list within 14 days of it.
- The financial statements to the DBD, with ส.บช.3, within 1 month of the AGM. Missing it fines the company and the director personally.
- [PND 50](/documents/pnd-50) within 150 days of year end. The Revenue Department’s FAQ is explicit that the return is due even with no income, and keeps being due until dissolution is registered and liquidation is complete.
- PND 51, the half-year estimate, in the middle of each accounting year.
The monthly set, if you are still registered for it
Registrations outlive activity. A VAT-registered company files PP 30 every month including nil months, with fines per missed return, until it formally deregisters, and deregistering from VAT has its own conditions. A company still registered as an employer keeps its social security filings until the employer registration is ended. Each of these is small on its own; together they are why a shelved company still needs an accountant on a small retainer.
Keep it or close it: the actual decision
A dormant company costs a predictable few tens of thousands of baht a year in audit, filings and a minimal bookkeeping retainer. That is worth paying if the company holds something, a licence, a lease, a bank history, or a planned restart. It is money down a hole if the business is simply over.
Closing properly, dissolution and liquidation through the DBD and a final tax clearance, is a real procedure with real cost, but it is paid once. If the company has no future, get quotes for closing it and compare that one-off number against the annual carry. Three or four dormant years usually pay for the closure.
