What Is PAYE in South Africa? (Pay As You Earn Explained)

🕑 3 min read  ·  FinCalcHub Editorial

How PAYE Works

1. Your employer calculates your projected annual income
2. They apply the SARS tax brackets to find your annual tax liability
3. They subtract your primary rebate (R17,235 in 2024/25)
4. They divide by 12 to get your monthly PAYE deduction
5. That amount is deducted from your gross salary and paid to SARS by the 7th of the following month

PAYE Calculation Example: R25,000/month Salary

What Reduces Your PAYE?

• Medical aid tax credits — R364/month for main member, R364 for first dependant, R246 for each additional
• Retirement Annuity contributions — deductible up to 27.5% of income, reducing your taxable income before PAYE is calculated
• Pension fund contributions — also deductible, same limits as RA (combined 27.5%)

PAYE vs Provisional Tax

PAYE applies to employees. If you earn additional income outside your salary (rental income, freelance work, investments), you may need to register as a provisional taxpayer and make two advance payments to SARS per year. Check with a tax practitioner if your additional income exceeds R30,000/year.

What If My PAYE Is Wrong?

SARS reconciles everything when you file your annual tax return (or via auto-assessment). If too much was deducted, you get a refund. If too little, you owe the difference. Common causes of underpayment: multiple employers in one tax year, bonus payments not taxed correctly, or untaxed investment income.

Worked Example: R45,000/month With Bonus and RA

Take a 35-year-old earning R45,000 a month (R540,000 annual base) who receives a R45,000 bonus in December and contributes R2,500 a month to a retirement annuity. The RA deduction of R30,000 a year reduces taxable income from R585,000 (salary plus bonus) to R555,000. That figure lands in the 31% bracket (R370,501 to R512,800 paid R77,362 plus 31% on amounts above R370,500).

Annual tax before rebates works out to R77,362 plus 31% of R184,500, which is R57,195 — giving a gross tax of R134,557. Subtract the primary rebate of R17,235 and the worker's R8,736 annual medical credit (assuming member-plus-one cover), and net tax is R108,586 for the year, or R9,049 a month after the bonus is "spread" across 12 months by the payroll system.

Standard PAYE deducted from each ordinary payslip (excluding the bonus month) is about R8,673 — slightly less than the eventual liability — because most payroll systems apply the year-to-date method that levels out the spike when the bonus pays. UIF deducts another R177.12 (1% on the first R17,712 of remuneration). Net take-home in an ordinary month is roughly R36,150 from a R45,000 gross — which means roughly 80c of every rand makes it through after PAYE and UIF.

Common PAYE Mistakes

• Treating the medical credit as a deduction — the R364/R364/R246 amounts are tax credits subtracted from PAYE owed, not from income. Some employers' payroll systems still get this wrong on manual setups, which inflates the deduction by a factor of three or four for medium earners.
• Switching jobs mid-year and assuming PAYE will balance out — both employers apply the rebate as if you only worked for them, so you can end up under-taxed and owe SARS at year-end. Always update your new employer with year-to-date earnings or request your previous IRP5.
• Not flagging RA contributions paid privately — payroll only knows about contributions deducted from your salary. If you set up a private RA debit order with Sanlam or Allan Gray, you must claim that deduction yourself on your eFiling return, because no PAYE adjustment was made during the year.
• Confusing PAYE with SITE — SITE (Standard Income Tax on Employees) was abolished in 2013. Anyone still using older payslip software with SITE columns is on outdated calculations. Modern SARS uses PAYE only, with provisional tax for non-salaried income.
• Assuming a thirteenth-cheque is "tax-free" — annual bonuses are taxed at the marginal rate. SARS only allows tax-free amounts on specific items like retrenchment severance (first R550,000 tax-free at lower rates), uniform allowances, and certain relocation costs.

FAQ

Why is my December PAYE so much higher than usual? The bonus or 13th cheque is taxed at your marginal rate. If your December gross is twice your usual amount, the additional amount sits at the highest bracket reached for the year. Many payroll systems use "annual spread" to smooth this — if yours does not, the spike is normal but recoverable when you file.

Who issues my IRP5 and when? Your employer issues an IRP5 by the end of May each year for the tax year that ended on 28 February. SARS auto-populates eFiling with the data, so if your IRP5 numbers do not match what payroll deducted, raise it with HR before submitting your return.

Can I claim home-office expenses if I work from home? Only if you have a dedicated office space used exclusively for work and your employer requires you to work from home more than half the year. The expense is calculated as a percentage of total home-running costs (rent, electricity, rates) based on the office's square meterage relative to the whole home.

What happens if my employer does not pay over my PAYE to SARS? SARS still credits you with the PAYE shown on your IRP5 — the employer is the one who faces penalties and prosecution for not paying it across. Always keep payslips as evidence of what was deducted in case the employer fails to issue an IRP5 or files incorrectly.

Sources and Methodology

PAYE calculations follow the SARS Employer Annual Reconciliation Guide and the published Income Tax Act Schedule 4 rules for the deduction of employees' tax. Rebate amounts and bracket thresholds come from the SARS "Rates of Tax" page for the 2025/26 year of assessment. UIF deductions follow the Unemployment Insurance Contributions Act limits as gazetted by the Department of Labour. Worked examples mirror the SARS PAYE deduction tables to the nearest rand.

Actionable Next Steps

1. Pull your last three payslips and verify the PAYE line matches a manual calculation using the SARS brackets.
2. Confirm with your employer that your tax reference number on the payslip is correct — mismatches cause IRP5 lookup failures at year-end.
3. If you have a private RA, ensure the certificate is uploaded against your eFiling profile before tax season opens.
4. Check your medical aid main-member and dependant count on payroll matches reality.
5. If you started a new job during the tax year, request a "tax directive" from SARS if your two combined incomes pushed you into a higher bracket.
6. Use the Take-Home Pay Calculator to model a salary increase and see exactly how much of it survives PAYE.
