Every entry below is the rule as South Africa publishes it. It is a reference, not a calendar: where a deadline runs from something only you know, this page says so instead of showing a date.
This is the rule as published by the registry, checked against the primary source on the date shown. It is not your filing date. Where a deadline runs from incorporation, from a fiscal year the company itself elects, or from an event only you know about, no date can be derived here at all — the figure you see is the formula, not the answer. Extensions, transitional regimes and entity-specific exemptions are not reflected. Confirm with the registry before you rely on a date.
A South African company's financial year is not fixed by statute: the company sets its own financial year end and the Commission records it. The Companies and Intellectual Property Commission states the limits in its own words — a company «may not choose a financial year end that will result in the total financial year being more than 15 months» and «may only change its financial year-end once during a particular financial year»; the new year end must fall later than the date on which the notice is filed, the current year end must not already have passed, and shortening a financial year carries no minimum length. The change is filed as «Company financial year end (CoR25)». The consequence matters more than the rule. Two of the duties below cannot be dated on this page at all until the company's own financial year end is supplied: the company income tax return is counted twelve months from that date, and the second provisional tax period falls on that date itself. Three duties do not run on this clock. The annual return, and the beneficial ownership and financial statement filings that travel with it, run from the anniversary of incorporation and do not move when the financial year end changes; the value added tax return runs on a tax period that the South African Revenue Service allocates.
