Q333182.When the receiving authority changes its form, what must filing the annual corporate income tax return adapt?
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.
