Compliance context
Built around documents and deadlines
A company does not file every form by default. PND 1, PND 3, PND 53, PND 54, PP30 and corporate income tax returns apply to different facts, so the current Revenue Department rules and filing calendar are checked before action.
Review company activity, tax registrations and prior filing history.
Map applicable returns to employees, vendors, VAT and cross-border payments.
Set document owners, monthly cut-offs and a question-resolution process.
Prepare filing information, resolve exceptions and obtain approval where required.
Track submission receipts, payments and issues for the next period.

FAQ
Questions before starting
Which monthly tax returns does a Thai company file?
It depends on payroll, payments to individuals or companies, VAT registration and cross-border transactions. The company profile should be reviewed before assigning forms.
Are PND 1, PND 3 and PND 53 the same?
No. They cover different withholding-tax situations and recipient types. Payment evidence and recipient status must be checked before selecting a return.
Is PP30 included in monthly tax filing?
PP30 is the monthly VAT return for a VAT-registered business. VAT records and filing are included only when they are part of the confirmed scope.
Can you review late or missing filings?
Yes. The first step is to reconcile prior returns, receipts, payments and source documents before confirming corrective work.
