How is a second job taxed in South Africa?

A second job is not taxed at a special rate. The problem is that each employer works out PAYE as if their salary is your only income, so each applies the tax rebate and the low brackets in full. Add the two jobs together and your real tax is higher than the two PAYE amounts combined, which is why people with two jobs so often owe SARS a lump sum on assessment.

Nothing is going wrong with the deductions themselves. Each employer is doing exactly what the PAYE system tells it to do with the slice of income it can see. The shortfall appears only when SARS adds your incomes together at year end.

Why the shortfall happens

PAYE is designed around a single employer who can see your whole salary. That employer applies the primary rebate once and runs your income up through the brackets in order. With two employers, neither can see the other, so:

• each one subtracts the full primary rebate, and the rebate gets counted twice; and
• each one taxes its salary starting from the bottom bracket, when in reality your second salary stacks on top of the first and is taxed at your higher marginal rate.

Both effects pull the combined PAYE below your true liability, and the difference becomes payable once SARS assesses your combined income.

A worked example

Take someone with two jobs in the 2026 year of assessment: Job A pays R180,000 and Job B pays R120,000. Both are taxed under the 2026 SARS table, which charges 18% up to R237,100, then R42,678 plus 26% on the slice above R237,100.

Each employer withholds as if its salary stands alone:

• Job A: R180,000 x 18% = R32,400, less the primary rebate R17,235 = R15,165
• Job B: R120,000 x 18% = R21,600, less the primary rebate R17,235 = R4,365
• Total PAYE withheld across the year = R15,165 + R4,365 = R19,530

Now SARS adds the jobs together. Your taxable income is R300,000, which reaches the second bracket:

• R300,000 less R237,100 = R62,900
• R62,900 x 26% = R16,354
• R42,678 + R16,354 = R59,032
• Less the primary rebate of R17,235 (applied once) = R41,797 tax for the year

Your real tax is R41,797 but only R19,530 was withheld, so you owe R22,267 on assessment. The rebate was double-counted by R17,235, and part of the second salary that each employer taxed at 18% should have been taxed at 26%.

How to avoid the year-end bill

You cannot stop two employers from each applying the standard tables, but you can ask one of them to deduct more. SARS lets you request that an employer withhold PAYE at a higher percentage so that the combined deductions track your real liability. You give the employer a higher fixed percentage to apply, based on your total expected income.

Where the second income is a pension or annuity rather than a salary, the fund can apply a fixed-rate directive from SARS for the same reason. The aim in both cases is to move some of the year-end shortfall into monthly PAYE so that less is left to settle on assessment.

If you do nothing, set the expected shortfall aside yourself, because the amount owing is real tax you were always going to pay rather than an extra charge for holding two jobs.

Work out your real combined tax

The fix starts with knowing your true liability. Our Basic income tax and PAYE calculator applies the 2026 SARS table and rebate to your combined income, so you can see the shortfall before SARS does. Our guide on how a bonus is taxed covers the same marginal-rate logic for extra pay, our explainer on how PAYE is calculated shows the single-employer mechanics this breaks, and if your second income is freelance rather than a salary, see who counts as a provisional taxpayer.
