South Africa Tax Guide 2024/25: Income Tax, Rebates & Thresholds

🕑 8 min read  ·  FinCalcHub Editorial

South Africa uses a progressive income tax system administered by SARS (South African Revenue Service). This guide covers everything you need to calculate your personal income tax liability for the 2024/25 tax year (1 March 2024 – 28 February 2025).

2024/25 SARS Income Tax Brackets

Taxable Income	Rate
R1 – R237,100	18%
R237,101 – R370,500	R42,678 + 26% of amount over R237,100
R370,501 – R512,800	R77,362 + 31% of amount over R370,500
R512,801 – R673,000	R121,475 + 36% of amount over R512,800
R673,001 – R857,900	R179,147 + 39% of amount over R673,000
R857,901 – R1,817,000	R251,258 + 41% of amount over R857,900
R1,817,001+	R644,489 + 45% of amount over R1,817,000

Tax Rebates (Deducted After Tax is Calculated)

Rebate	Amount	Who qualifies
Primary rebate	R17,235	All taxpayers
Secondary rebate	R9,444	Age 65–74
Tertiary rebate	R3,145	Age 75+

Tax Thresholds (Below This = No Tax)

Age	Tax threshold
Under 65	R95,750
65–74	R148,217
75+	R165,689

Worked Example: R480,000 Annual Income

1. Tax on R370,500: R77,362
2. Tax on remaining R109,500 at 31%: R33,945
3. Gross tax: R77,362 + R33,945 = R111,307
4. Less primary rebate: −R17,235
5. Tax payable: R94,072 (effective rate: ~19.6%)

Medical Tax Credits

Medical scheme contributions qualify for a tax credit (not a deduction):

Members	Monthly credit
Main member	R364
First dependant	R364
Each additional dependant	R246

A main member + 1 dependant gets R728/month = R8,736/year off their tax bill.

Retirement Annuity Deduction

RA contributions are tax-deductible up to 27.5% of the greater of taxable income or remuneration, capped at R350,000/year. Contributing R3,000/month to an RA on a R480,000 salary saves approximately R11,160/year in tax (at 31% marginal rate).

UIF (Unemployment Insurance Fund)

Both employee and employer contribute 1% of remuneration each, capped at the monthly income threshold. The employee contributes 1% of gross monthly income (on income up to R17,712/month). This is a mandatory deduction from payslips.

Key SARS Dates

• Tax year: 1 March – 28/29 February
• Auto-assessment: July/August (SARS uses employer and third-party data)
• eFiling returns: July – November for non-provisional taxpayers
• Provisional tax: First payment August, second February

Worked Example: R720,000 Salary With Medical Aid and RA

Consider a 38-year-old earning R720,000 a year, contributing R36,000 to a retirement annuity and belonging to a medical scheme with one dependant. The RA contribution is fully deductible (R36,000 is below the 27.5% cap of R198,000), so taxable income drops to R684,000. That falls in the R673,001–R857,900 bracket, so tax is R179,147 plus 39% of R11,000, which equals R183,437 before rebates.

From that gross tax figure, subtract the primary rebate of R17,235 and the annual medical tax credit of R8,736 (R728 a month for member plus first dependant). Net annual income tax is R157,466, an effective rate of about 21.9% on the full R720,000. UIF deducts another 1% of monthly remuneration up to the R17,712 ceiling, adding R2,125 a year. Take-home after tax and UIF lands at roughly R560,409 — that is R46,701 a month.

Without the RA contribution, taxable income would have stayed at R720,000 and income tax would have climbed by roughly R14,040 (R36,000 × 39% marginal rate). The R36,000 RA effectively cost the taxpayer R21,960 in after-tax money while building R36,000 in pension savings — that is the headline benefit of the deduction at the higher SARS bands.

Common Mistakes With SA Personal Tax

• Treating rebates as deductions — the primary rebate of R17,235 is subtracted from your calculated tax, not from your income. People who mistakenly subtract it from gross income before applying the brackets vastly overstate their refund expectation.
• Forgetting the RA cap works on the higher of taxable income or remuneration — provisional taxpayers with investment income often miscalculate the 27.5% deduction by using the wrong base. SARS lets you choose whichever number is larger, and the cap of R350,000 only bites at very high incomes.
• Claiming medical expenses without exceeding the threshold — out-of-pocket medical costs are only deductible to the extent they exceed 7.5% of taxable income (or different rules for over-65s and disability). Most working-age taxpayers see no benefit from these claims because their unreimbursed costs sit below the floor.
• Missing the August provisional tax payment — anyone with non-PAYE income above the threshold (rental, freelance, dividends from a private company) is a provisional taxpayer. SARS imposes a 10% penalty plus interest if the August IRP6 submission underestimates by more than the prescribed margin.
• Assuming auto-assessment is final — SARS auto-assessments use employer and third-party data only. If you have RA contributions paid privately, travel claims, home-office expenses, or solar tax credits, you must "edit and submit" the return to claim them — accepting the auto-assessment as-is forfeits those deductions.

FAQ

What is the tax-free threshold for under-65s? R95,750. This is the income level at which the primary rebate of R17,235 exactly cancels out the 18% tax on the first R95,750 of earnings (R95,750 × 18% = R17,235). Anyone earning below this pays zero income tax.

Does the 13th cheque get taxed differently? No — a 13th cheque (annual bonus) is taxed at your marginal rate as ordinary income. SARS allows employers to spread the PAYE deduction across the year ("annual spread") so the December paycheque is not hit with disproportionate tax in a single month.

Are foreign earnings taxed in South Africa? Yes. South Africa uses a residence-based system. Tax residents must declare worldwide income. The "foreign employment income exemption" exempts the first R1.25 million of foreign salary if you spent more than 183 days outside SA over a 12-month period with at least 60 continuous days abroad.

How does the solar tax credit work? Individuals can claim 25% of the cost of new solar PV panels (panels only, not inverters or batteries), capped at R15,000. The credit applies to panels installed and brought into use between 1 March 2023 and 29 February 2024 — it was a once-off incentive, not an ongoing relief.

Sources and Methodology

Brackets, rebates, thresholds, and medical tax credits are taken directly from the SARS website ("Rates of Tax for Individuals") and the National Treasury Budget Review for 2024/25 and 2025/26. The retirement annuity deduction rules follow Section 11F of the Income Tax Act as amended in the 2016 retirement reform. UIF contribution ceilings reflect the most recent Department of Labour gazette. Worked examples apply the published bands without rounding intermediate steps so the answers match a SARS PAYE deduction lookup table to the nearest rand.

Actionable Next Steps

1. Log in to SARS eFiling and verify that your tax reference number, banking details, and IRP5 data from your employer are correct.
2. If you contribute to a retirement annuity privately (not through payroll), make sure your tax certificate is issued — without it the deduction cannot be claimed.
3. Check whether your medical scheme issued an IT3(f) certificate showing the months covered and number of dependants.
4. If you have rental income or freelance work above R30,000 a year, register as a provisional taxpayer to avoid penalties.
5. Use our Take-Home Pay Calculator to compare current take-home with the impact of increasing your RA by R1,000 a month.
6. File your annual return between July and November — earlier submission usually means a faster refund.

Provisional tax and the self-employed

If you earn income from sources outside a single employer — freelance work, rental income, business profits, significant dividends — SARS expects you to register as a provisional taxpayer and pay tax in two instalments each year (end August and end February), with an optional third top-up by end September. Provisional tax is not an additional tax; it is the same income tax paid in advance based on estimated annual taxable income, which avoids one large bill at year-end. The penalties for under-estimation are real: if your second-period estimate is below 80% (or 90% for higher earners) of actual taxable income, SARS levies a 20% under-estimation penalty plus interest. The practical approach is to recalculate the estimate each February using the eight months of bank data you already have, rather than relying on the prior year's number. SARS publishes the IRP6 form and a guide at sars.gov.za/types-of-tax/provisional-tax/.
