A March–February year, handled properly, and no e-invoicing mandate to block anything.
South Africa is among the lower-effort markets on this list for a specific reason: SARS VAT201 and EMP201 are periodic forms rather than a real-time clearance mandate, so there is no e-invoicing integration standing between a contractor and using the system. The financial year runs from 1 March, which Rebota resolves per company — including the February year-end in a leap year, which is the kind of detail that quietly breaks systems with April–March assumed in twenty places. The remaining gap is the return itself, which your accountant prepares from data Rebota holds in full.
This page is the intersection. The country page covers currency, financial year and statutory position in detail; the sector page covers what is built, the turnover bands it suits, and what is missing regardless of country.
