What does a statutory audit cost in Thailand?
A dormant company is audited for about 4,000 to 7,000 baht a year, and a trading company is priced by revenue, typically 10,000 to 30,000 baht up to 30 million baht of turnover. Every Thai company must be audited by a licensed CPA whatever its size, including one that made a loss and one that did not trade at all.

Dormant, no activity
4,000 to 7,000 / year
Sometimes called งบเปล่า, blank accounts. Still legally required.
Under 10 million baht revenue
10,000 to 22,000 / year
The band most SMEs sit in. Priced off turnover, not effort.
10 to 50 million baht revenue
22,000 to 50,000 / year

The audit is not optional, and it is not the bookkeeping
Every Thai limited company files audited financial statements every year, signed by a CPA licensed in Thailand. That holds if you made a loss, and it holds if the company never traded. The auditor must be independent of whoever kept the books, so your bookkeeper cannot audit their own work.
This catches people out because the monthly accounting fee almost never includes it. Check whether your bookkeeping quote covers the audit, and if it does, ask who signs.
The spread on identical work is the real finding
At roughly one million baht of revenue, published fees in our sample run from 6,000 to 15,000 baht for the same statutory audit. That is not a difference in scope. It is a difference in what each firm thinks the market will pay, and it is the clearest case on this whole site for getting more than one quote.
What moves an audit fee
- Annual revenue, which is what almost every published table is banded on.
- Whether the books are already clean. An auditor asked to fix the bookkeeping first will charge for it.
- Foreign shareholding and any group or IFRS reporting pack on top of the Thai statutory accounts.
- How late you are. Several firms publish a rush surcharge, one of them 20 to 30 percent.

How we got these numbers
We read the public pages of 41 firms that publish something for this category, out of more than two hundred researched. No firm was contacted, no enquiry form was submitted, and nobody posed as a customer, which is the thing our own terms forbid customers to do to providers. Prices were taken only from a firm’s own domain, never from a directory or a comparison site, and never converted between currencies.
Published prices move, and a page can go stale between our reviews. This is a guide to what the market prints, not a quote, and not accounting or legal advice for your company. Found one that has changed? Tell us and we will fix it.
