Does a Thai company with zero revenue still need an audit?
Yes. Every Thai limited company must have its financial statements audited and signed by a licensed auditor every year, and the Accounting Act makes no exception for a company that did not trade. The only audit exemption in the law is for small registered partnerships, never for companies, so a dormant company carries a small audit fee for every year it stays on the register.

Where the obligation comes from
Section 11 of the Accounting Act B.E. 2543 requires financial statements to be examined and opined on by a licensed auditor, ผู้สอบบัญชีรับอนุญาต. The test is whether the company exists, not whether it earned anything: a company that sat idle all year still closes its books, still produces a balance sheet, and still needs a CPA to sign it.
The tax side says the same thing. The Revenue Department’s own FAQ on PND 50 states that a company must prepare financial statements and file the return even with no business income, and that a company which has stopped operating keeps filing until the dissolution is registered and the liquidation is complete.
The one real exemption, and why it is not you
The Accounting Act lets a ministerial regulation exempt small registered partnerships from the audit. In practice the thresholds are the ones the Revenue Department repeats for tax auditors: registered capital of 5 million baht or less, total assets of 30 million or less, and total revenue of 30 million or less. A partnership inside all three can have its accounts certified by a tax auditor (TA) rather than a CPA.
What zero revenue changes is the price
An audit of a company with no activity, often called งบเปล่า, blank accounts, is the cheapest audit there is: firms publish prices of roughly 4,000 to 7,000 baht a year for it. What audits cost, by revenue band has the published figures and who they come from.
Skipping it is not a saving. Filing statements that were never audited is its own offence under the Act, with a fine of up to 20,000 baht, and not filing at all exposes the company and its director to the DBD’s late filing fines plus a fine of up to 50,000 baht for the underlying offence.
If the company has genuinely finished its life, the clean exit is to dissolve and liquidate it, after which the annual cycle actually stops. What still has to be filed while it is dormant walks through the full list, and closing the company properly is a service worth pricing against years of dormant filings.
