FAQ
Questions before starting
Does every Thai company use the same financial year?
No. Work should follow the company’s registered accounting period and prior filings, not an assumed calendar or government fiscal year.
Does every company need the same audit workflow?
No. Auditor involvement and filing documents depend on the entity type and current legal requirements, so they are confirmed before scope is agreed.
When is PND 50 filed?
The Revenue Department states that the annual corporate income tax return is filed within 150 days from the closing date of the accounting period. The current filing method and company facts still need confirmation.
Can incomplete or late annual records be fixed?
Usually the next step can be mapped after reviewing the ledger, prior submissions, missing documents, audit status and open deadlines.
