THE RULES WE WORK TO

What Thai law requires of a limited company's books

Four obligations sit behind every year-end close. We build the monthly books around them so the annual filings are a formality.

  1. Accounting Act B.E. 2543

    A Thai limited company has a legal duty to keep accounts (section 8) and to prepare financial statements for every accounting period (section 11).

    Source: Accounting Act B.E. 2543 (English text)

  2. CPA audit every year

    A limited company's financial statements must be audited and signed off by an authorized auditor (CPA) under section 11. The Act's audit exemption applies only to small Thai registered partnerships below thresholds set by ministerial regulation, not to limited companies.

    Source: Accounting Act B.E. 2543 (English text)

  3. PND.50 within 150 days

    The annual corporate income tax return (PND.50), with the audited accounts, is due within 150 days of the last day of the accounting period under Revenue Code sections 68 and 69.

    Source: Revenue Department: Revenue Code sections 68 and 69

  4. Financial statements to the DBD

    Once shareholders approve the audited financial statements at the AGM, the company submits them to the Department of Business Development within one month (section 11).

Deadlines shift when they fall on a weekend or public holiday. Settlr Global's platform tracks the exact date for your fiscal year and files ahead of the deadline, not on it.

SWITCHING PROVIDERS

Moving your books to Settlr Global, without a gap in filings

Most SMEs switch accountants mid fiscal year, worried about losing continuity. Here is exactly how the handover works so no filing is ever missed in the transition.

  1. Share access and historical records

    You grant read access to your current bookkeeping file (or export it) plus the last 12 months of filed PND and PP.30 returns, bank statements, and the latest audited financials.

  2. Settlr Global reconciles the opening balance

    Our team rebuilds the trial balance from your existing records and reconciles it against bank statements and prior filings before touching anything new.

  3. We confirm filing status with the Revenue Department

    We verify there are no outstanding filings, penalties, or open queries on your tax ID before assuming responsibility for the next filing cycle.

  4. Your next deadline is covered on our calendar

    Whichever filing is next due (PND.1, PP.30, or PND.50), it goes onto the Settlr Global platform calendar immediately, with the current provider's numbers as the baseline.

  5. Old provider is notified and offboarded

    We coordinate a clean handover date with your outgoing accountant so there is no double-filing, no missed month, and no ambiguity about who owned which filing.

Typical handover takes 1 to 2 weeks and can start at any point in your fiscal year.

Numbers you can defend

How we keep your accounting and tax operation steady – so audits, board meetings, and Revenue Department reviews are non-events.

  • Audit-ready records

    Every entry traced to a source document. When the auditors arrive, the package is already prepared and the supporting files are linked, not scattered.

  • Real-time numbers

    Books are closed within five business days of period end. You see this month's revenue and margin while it still matters, not after the next quarter is half over.

  • Zero missed filings

    Every PP.30, PND.50, PND.51, PND.3, and PND.53 tracked against statutory due dates. Penalties and surcharges never land on your desk.

Questions

Before you file

What is the corporate income tax rate in Thailand?

The standard corporate income tax rate is 20 percent of net profit. Qualifying SMEs pay 0 percent on the first 300,000 THB, 15 percent up to 3 million THB, and 20 percent above that. BOI promoted companies can receive corporate income tax holidays of up to 13 years depending on activity.

When do I need to register for VAT in Thailand?

VAT registration is mandatory once annual revenue exceeds 1.8 million THB. The standard VAT rate is 7 percent, and registered companies file the PP.30 return monthly by the 15th of the following month (23rd if e filed). Settlr Global handles registration and every monthly filing.
