Thailand Statutory Filing Service

The flat fee covers all applicable monthly filings (PND1, PND3, PND53, PND54, PP30, PP36, SSO) and all applicable annual filings (PND51, PND50, PND1 Kor, DBD financial statement and shareholders' list submission) for one company. Not every filing applies to every company — a non-VAT-registered company doesn't file PP30, for example. During onboarding we identify exactly which forms your company is required to submit and the fee covers that specific scope. Government fees, penalties for late filings caused by late data submission, and additional services (tax advisory, auditor liaison) are not included.

After onboarding, we provide a structured monthly data template specific to your company's filing obligations. Typically this covers: total salary and tax withheld per employee (for PND1), total payments to Thai individuals and companies with applicable withholding rates (PND3/53), total output and input VAT for the month (PP30), and SSO contribution confirmation. We don't need raw transaction data or accounting system access — just the filing-ready figures. For the annual corporate income tax return (PND50) your team provides the tax computation; we prepare and submit the form.

We file on the data we receive — we cannot file before we have it. If data arrives after the statutory deadline, the filing will be late and government penalties will apply automatically. Revenue Department surcharges are 1.5% per month on underpaid tax plus THB 100–500 per late form. SSO late contributions attract a 2% per month surcharge. These penalties are not within our control and are not covered by the service fee. To help prevent this, we send deadline reminders in advance of each cut-off date and keep the data requirements as simple as possible.

No. The service covers submitting the PND50 and PND51 forms to the Revenue Department — it does not include preparing the corporate income tax computation. Your overseas accounting team produces the computation and provides us with the final figures. If your team needs support with the Thai tax computation specifically, this is available as a separate advisory service — contact us and we can arrange an appropriate engagement.

Yes — submission of audited financial statements to the DBD and the post-AGM shareholders' list (Bor Or Jor 5) are both included. The financial statements must be audited by a Thai-licensed auditor and approved at the AGM before we can submit them. The service does not include organising the AGM, preparing AGM documentation, or liaising with your auditor — those are handled separately through our corporate secretarial service if needed.

This service works well for companies that have a competent accounting team outside Thailand — a regional finance function, group controller, or overseas accounting firm — who handles the bookkeeping and tax computations but cannot legally submit Thai government filings themselves. It also works for companies with a Thai accountant who handles the accounts but prefers to outsource the government portal submissions to a dedicated compliance team. It is not suitable for companies that need bookkeeping, accounting records, or tax advice included — for those, our full accounting and tax service is more appropriate.
