Small Business Tax Calculator
Small Business Corporation (SBC) Tax Calculator
Check if your company qualifies as a Small Business Corporation and see what the reduced SBC rates could save you.
How it works: A qualifying SBC pays tax on a sliding scale instead of the flat 27% company rate. To qualify, all shareholders must be individuals, gross income must be R20 million or less, and it cannot be a personal service provider or hold shares in other companies.
