Quick Answer: How is income tax calculated in South Africa 2026/2027?

South African income tax is calculated by applying the SARS 2026/2027 progressive tax brackets (18%–45%) to your taxable income, then subtracting your age-based rebate (R17,820 to R29,824) and medical aid tax credits. The result is your annual income tax payable. Divide by 12 for your monthly PAYE amount.

How South African Income Tax Works

South Africa uses a progressive income tax system — meaning different portions of your income are taxed at different rates. As your income increases, higher portions are taxed at higher rates. However, only the income in each bracket is taxed at that bracket’s rate — not your entire income.

Your final tax liability is calculated in this order: gross tax from brackets → minus rebates → minus medical aid credits → equals net tax payable. Allowable deductions (pension, RA, travel) reduce your taxable income before the brackets are applied.

SARS collects income tax from employees monthly through the PAYE system. Your employer deducts PAYE from your salary and pays it directly to SARS. At year-end, you file an ITR12 return to reconcile your total tax. Read our guide on PAYE calculators South Africa 2026 for monthly calculations.

2026/2027 SARS Income Tax Brackets

These are the official SARS tax brackets for the 2026/2027 tax year (1 March 2026 — 28 February 2027):

Taxable Income (Annual)	Marginal Rate	Base Tax	Tax on Excess
R0 – R245,100	18%	R0	18% of taxable income
R245,101 – R383,100	26%	R44,118	+ 26% above R245,100
R383,101 – R530,200	31%	R79,998	+ 31% above R383,100
R530,201 – R695,800	36%	R125,599	+ 36% above R530,200
R695,801 – R887,000	39%	R185,215	+ 39% above R695,800
R887,001 – R1,878,600	41%	R259,783	+ 41% above R887,000
R1,878,601 and above	45%	R666,339	+ 45% above R1,878,600

Important: These rates apply to your taxable income — not your gross salary. Allowable deductions like pension fund and RA contributions reduce your taxable income before these brackets are applied.

Step-by-Step Income Tax Calculation Method

Here is exactly how SARS calculates your annual income tax — the same method used by employers for monthly PAYE:

Step 1 — Determine gross income

Start with your total annual gross income from all sources — salary, rental income, freelance income, investment returns, and any other taxable receipts.

Step 2 — Subtract allowable deductions

Deduct pension fund and RA contributions (up to 27.5% of income, max R430,000/year). This gives you your taxable income — the amount on which tax is calculated.

Step 3 — Find your tax bracket

Locate your taxable income in the 2026/2027 SARS tax table above. Take the base tax for your bracket and add the marginal rate applied to the excess above the bracket threshold.

Step 4 — Subtract your rebate

Deduct the primary rebate (R17,820). If aged 65–74, also deduct R9,765. If 75+, also deduct an additional R3,249. Rebates directly reduce your tax bill — not your taxable income.

Step 5 — Subtract medical aid credits

Deduct R376/month × 12 for yourself, R376/month × 12 for your first dependant, and R254/month × 12 for each additional dependant. These credits reduce tax payable further.

Step 6 — Result is your annual income tax

The remaining amount is your annual income tax payable. Divide by 12 for your monthly PAYE deduction. The difference between PAYE paid and actual tax owed is your refund or balance due.

Tax Rebates and Tax Thresholds 2026/2027

Tax rebates are fixed amounts that reduce your final tax bill — they are NOT deductions from income. Every South African taxpayer receives a primary rebate:

Rebate	Annual Amount	Cumulative Total	Who Qualifies
Primary Rebate	R17,820	R17,820	All taxpayers
Secondary Rebate	R9,765	R26,679	Age 65 – 74
Tertiary Rebate	R3,249	R29,824	Age 75 and older

Age Group	Tax-Free Threshold (Annual)	Monthly Equivalent
Under 65	R99,000	R8,250/month
65 – 74 years	R153,250	R12,771/month
75 years and older	R171,300	R14,275/month

Medical Aid Tax Credits 2026/2027

Medical aid tax credits (MTC) reduce your tax payable — not your taxable income. They are applied after rebates:

Medical Aid Member	Monthly Credit	Annual Credit
Principal member (yourself)	R376	R4,512
First dependant	R376	R4,512
Each additional dependant	R254	R3,048

For example, a family of 4 (yourself + 3 dependants) would have annual MTC of: R4,368 + R4,368 + R2,952 + R2,952 = R14,640/year — directly reducing your tax bill.

Key Deductions That Reduce Your Taxable Income

Pension Fund / RA

Maximum 27.5% of taxable income or remuneration — whichever is greater — capped at R430,000/year. Unused deductions carry forward to future years.

Travel Allowance

Business km × SARS approved rate for your vehicle value. Requires a logbook. 80% of travel allowance is included in taxable income — the logbook deduction offsets this.

Home Office

Proportional home expenses for a dedicated workspace — calculated as (office m² ÷ total m²) × qualifying annual costs. Employer must permit home working in writing.

Section 18A Donations

Donations to SARS-approved PBOs — deductible up to 10% of taxable income. Requires a valid Section 18A receipt from the organisation.

Worked Calculation Examples — 2026/2027

Example 1 — R25,000/month salary, under 65, no medical aid, no RA

Annual income	R300,000
Gross tax: R44,118 + 26% × (R300,000 − R245,100)	R44,118 + R14,274 = R58,392
Less primary rebate	− R17,820
Annual tax payable	R41,157
Monthly PAYE	R3,430/month
Monthly take-home	R21,570/month

Example 2 — R55,000/month salary, under 65, 2 medical aid members, R5,000/month RA

Annual gross income	R660,000
Less RA deduction (R5,000 × 12)	− R60,000
Taxable income	R600,000
Gross tax: R125,599 + 36% × (R600,000 − R530,200)	R125,599 + R25,128 = R150,729
Less primary rebate	− R17,820
Less medical aid credits (2 × R376 × 12)	− R9,024
Annual tax payable	R124,758
Monthly PAYE	R10,397/month
Monthly take-home (after PAYE + UIF)	R43,878/month

Example 3 — R15,000/month salary, under 65, no medical aid, no RA

Annual income	R180,000
Gross tax: R180,000 × 18%	R32,400
Less primary rebate	− R17,820
Annual tax payable	R15,165
Monthly PAYE	R1,264/month
Monthly take-home	R13,586/month

Marginal vs Effective Tax Rate — What Is the Difference?

Many South Africans confuse their marginal tax rate with their effective tax rate. Here is the key difference:

Concept	Definition	Example (R420,000 income)
Marginal Rate	The rate applied to your last rand of income	31% (falls in R383,101–R530,200 bracket)
Effective Rate	Total tax ÷ total income — your average rate	Approximately 18–20% after rebates
Why it matters	Marginal rate is used for decisions about extra income	Every extra rand earned at R420k is taxed at 31%

Understanding your marginal rate is essential for decisions like whether to invest in an RA — since every rand contributed saves tax at your marginal rate. Use our income tax calculator to see both your marginal and effective rates.

Frequently Asked Questions — Income Tax Calculation South Africa 2026

How much tax do I pay on R300,000 per year in South Africa 2026? +

On R300,000 annual income (under 65, no deductions, no medical aid): Gross tax = R44,118 + 26% × (R300,000 − R245,100) = R58,392. Less primary rebate R17,820 = R41,157 annual tax. Monthly PAYE = R3,430. Monthly take-home ≈ R21,570 after PAYE and UIF.

What is the tax-free threshold in South Africa for 2026/2027? +

For 2026/2027: R99,000/year (R8,250/month) for taxpayers under 65. R153,250/year for those aged 65–74. R171,300/year for those 75 and older. If your income is below these thresholds, you pay no income tax and your employer should not deduct PAYE.

Does my retirement annuity contribution reduce my tax? +

Yes — significantly. RA contributions are deductible up to 27.5% of your taxable income or remuneration (whichever is higher), capped at R430,000/year. The deduction reduces your taxable income before the tax brackets are applied — saving tax at your marginal rate. For a taxpayer in the 31% bracket, every R1,000 contributed to an RA saves R310 in tax.

How are medical aid tax credits different from a deduction? +

A deduction reduces your taxable income (the amount on which tax is calculated). A tax credit directly reduces your tax bill rand-for-rand. Medical aid tax credits (R376 + R376 + R254 per dependant per month) are credits — meaning they reduce your final tax payable directly, regardless of your marginal tax rate. This makes them more valuable for lower-income earners than deductions would be.

What is the highest income tax rate in South Africa 2026? +

The highest marginal income tax rate in South Africa for 2026/2027 is 45% — applied to taxable income above R1,878,600 per year. However, due to the progressive system and rebates, the effective (average) tax rate for someone earning R1,878,600 is approximately 33–35% — not 45%.

How do I calculate income tax if I have two jobs? +

If you have two employers, you must declare both IRP5 incomes on your annual ITR12 return. SARS adds both incomes together and calculates your tax on the combined total. Each employer deducts PAYE based only on the salary they pay — meaning the combined PAYE may be less than the tax owed on total income. This often results in a tax debt when you file your annual return.

Is rental income taxed differently in South Africa? +

No — rental income is taxed at the same progressive rates as salary income. It is added to your other income and taxed at your marginal rate. However, you can deduct allowable expenses against rental income — bond interest, rates and taxes, insurance, agent fees, and wear and tear on appliances. The net rental income (income minus expenses) is added to your taxable income.

How do tax brackets work in South Africa — am I taxed at 31% on all my income? +

No — South Africa uses a progressive system. If you earn R420,000/year, you are NOT taxed at 31% on the full R420,000. The first R245,100 is taxed at 18%, the next R138,000 (to R383,100) at 26%, and only the remaining R36,900 at 31%. This is why your effective tax rate is always lower than your marginal rate.

What changed in the 2026/2027 tax brackets compared to 2025/2026? +

For 2026/2027, SARS adjusted the tax brackets upward for inflation relief — meaning bracket thresholds increased, resulting in slightly less tax on the same income. The rebates also increased: primary rebate R17,820, secondary R9,765, tertiary R3,249. Medical aid credits increased to R376 for the first two members and R254 for additional dependants.

How do I reduce my income tax legally in South Africa? +

The most effective legal tax-reduction strategies in South Africa include: maximising your RA/pension contribution (saves tax at your marginal rate), ensuring medical aid is in your name to claim credits, keeping a travel logbook if you receive a travel allowance, claiming home office expenses if permitted by your employer, making donations to Section 18A organisations, and investing via a Tax-Free Savings Account (TFSA) for investment income. Use our income tax calculator to see the impact of each strategy.
