The trade-off
A salary is an expense for the company, so it saves company tax at 27%, but you pay PAYE on it at up to 45%, plus UIF. A dividend is paid from profit after company tax, and 20% dividends tax is withheld, so profit paid out as a dividend carries about 41.6% in total.
Where the balance usually falls
A small salary is almost always worth taking: under 65, the first R99,000 a year carries no PAYE at all, and every rand of it saves company tax. Above that, it depends on your PAYE bracket. This calculator compares all dividends, your mix and all salary, so you can see which leaves you more.
What it assumes
The company pays out all its profit after tax as a dividend in the same year, you have no other income, and you’re under 65 with no medical aid or retirement contributions. Real life is rarely that tidy, so treat the answer as a starting point for a conversation with your accountant.
