Contractor vs Employee: Why Your Tax Is So Different

"Should I go permanent or contract?" is one of the most common money questions in South African working life, and tax is a big part of the answer. The headline rate is the same — independent contractors pay income tax on the same sliding scale as employees — but almost everything around it differs, and those differences catch people out.

As an employee, your tax life is largely automatic. Your employer calculates PAYE, deducts it monthly, and pays it over to SARS. UIF comes off too, and your employer adds their share. You get an IRP5 at tax time and your annual return is usually straightforward. The money you see in your account is genuinely yours.

As an independent contractor, much more lands on you. Depending on how you're engaged, tax may not be deducted before you're paid — meaning the full amount hits your account and you are responsible for setting aside and paying the tax yourself, usually twice a year as a provisional taxpayer. This is where contractors get into trouble: that money in the account feels like income, but a large chunk of it belongs to SARS, and spending it before provisional tax is due is a painful, common mistake. A rough rule of thumb is to park 25–35% of contractor income aside, depending on your earnings level, though your real figure depends on your bracket.

Contractors generally don't have UIF deducted, and aren't covered by it — so the safety net that employees have isn't there. On the other side of the ledger, genuine contractors can often deduct legitimate business expenses against their income, which employees usually can't. Whether you're a "genuine" independent contractor in SARS's eyes depends on the substance of the working relationship, not just what the contract calls you — and getting that classification wrong has consequences, so it's worth proper advice if you're unsure.

The practical takeaway: a contract rate and a salary of the same headline number are not equivalent. The contractor figure has to cover tax you'll pay yourself, the absence of UIF and benefits, and your own provision for leave and gaps between contracts. When comparing an offer, compare take-home after all of that, not the gross numbers.

This is general information, not tax advice. To compare employee and contractor take-home pay on the same salary, use the calculator and switch modes.
