Q333086.With a tight travel date, what contingency plan suits filing the annual corporate income tax return?
A juristic person files the half-year corporate income tax return (PND.51) within two months of the end of the first six months, and the annual return (PND.50) with audited financial statements within 150 days of the accounting-period end, under the Revenue Code. If a loan, licence renewal or visa application depends on the figures, allow lead time to close the books and obtain certified copies. Watch out: withholding at the wrong rate or remitting late triggers the 1.5% monthly surcharge and an amended return. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th).
