Every Thai limited company needs an annual audit, however small. After your fiscal year end, one team manages the whole sequence: books closed, auditor engaged, AGM held, financial statements filed with the Department of Business Development (DBD), and the PND 50 tax return submitted, with every deadline met.

Who this is for
Every Thai limited company needs an annual audit. Our support makes the biggest difference in these situations.
Thai limited companies (บริษัทจำกัด) of any size, including dormant ones
The audit is mandatory under the Accounting Act: even a company with no revenue must file audited statements with the DBD every year. A dormant company that skips two years faces accumulated fines and a backlog that costs far more to clear than staying current.
Foreign-led SMEs with THB 5–50 million revenue and 5–30 staff, in their first full year
New companies often underestimate the post-year-end deadlines and discover the audit requirement in month 5, too late to engage an auditor, complete fieldwork, hold the AGM, and file by the May deadline.
Subsidiaries of foreign groups with THB 20–100 million revenue
The audited Thai statements must reconcile with the parent's IFRS reporting pack, and the signed audit must arrive in time for the group close (usually February–March for a December year end). A late Thai audit delays the whole group.
Companies with BOI promotion
The BOI relies on audited statements to check that the investment plan is carried out, that promoted and non-promoted activities are kept separate, and that tax holidays still apply. A qualified opinion or a late filing can trigger a BOI compliance review.
Companies preparing to raise funds, sell, or exit
Investors and buyers expect 2–3 years of clean audited financial statements. Gaps, qualified opinions, or late filings lead to price discounts or failed deals.

There is no exemption for size or revenue. Even dormant companies must file audited statements with the DBD every year, and missed filings bring fines for the company and its directors.
For a December year end: AGM by 30 April, Bor.Or.Jor.5 within 14 days of it, DBD filing within 1 month of it, and PND 50 within 150 days of year end. We remind you of each step well in advance.
Clients on a Plizz monthly bookkeeping package pay no extra fee for audit preparation: schedules, working papers, and CPA hand-off are part of the monthly fee.
We have worked with our partner CPA firm for years. Because the books arrive clean and in a format the auditor knows, audits are usually faster and cheaper than when an auditor starts from raw books.
Common Questions
Answers to the most common questions before and during engagement.

The annual audit goes smoothest when bookkeeping, financial reporting, and tax filing sit with the same team, because the deadlines depend on each other.
Clean monthly books cut audit time, audit fees, and the risk of a qualified opinion; audit preparation is included in every Plizz bookkeeping package. Monthly packages start from THB 14,900/month.
The audit reviews the financial statements that reporting produces. Statements prepared to Thai Financial Reporting Standards for Non-Publicly Accountable Entities (TFRS for NPAEs, revised 2022) need less audit fieldwork.
PND 50 must reconcile with the audited statements and be filed within 150 days of year end. Our tax team follows the audit schedule and prepares PND 50 in parallel, so there is no rush in May.
DBD e-Filing account setup, registration of digital signatories, and Bor.Or.Jor.5 shareholder list updates filed alongside the annual audit, all in the same engagement.
