How progressive tax brackets work — the most common misconception corrected

You do NOT pay your bracket rate on your entire income.

This is the most common misunderstanding about South African income tax. Each rand of income is only taxed at the rate of the bracket it falls into — not at the rate of your highest bracket.

Think of it like steps. The first R245,100 of anyone's income is taxed at 18% — even if they earn R5 million. The 45% rate only applies to the portion of income above R1,878,600. Every taxpayer pays the same rate on the same slice of income.

Example: R400,000 annual taxable income

Someone earning R400,000 is technically "in the 31% bracket" (R383,101–R530,200).

But they do NOT pay 31% on R400,000. Here is how the tax is actually calculated:

Portion of income Rate Tax
First R245,100 18% R44,118
Next R138,000 (R245,101–R383,100) 26% R35,880
Remaining R16,900 (R383,101–R400,000) 31% R5,239
Total before rebates R85,237
Less: Primary rebate (R17,820)
Income tax payable R67,417
Effective tax rate 16.9%

Notice: the effective rate (16.9%) is far lower than the marginal rate (31%). The "31% bracket" describes only the rate on the last slice of income.

  • Marginal tax rate — the rate that applies to your last (highest) rand of income; the rate of the bracket your top income falls into
  • Effective tax rate — your total tax as a percentage of your total income; always lower than your marginal rate
  • Tax rebate — a flat rand amount deducted directly from your calculated tax (not from your income)

How much income tax do you pay? — Worked examples

The following examples calculate annual income tax using the 2026/2027 brackets, primary rebate (R17,820), and no other deductions.

Example 1: R15,000/month (R180,000/year) — entry-level salary
Step Calculation Amount
Annual taxable income R15,000 × 12 R180,000
Tax on R180,000 18% × R180,000 R32,400
Less: Primary rebate (R17,820)
Annual income tax R14,580
Monthly tax (PAYE) R14,580 ÷ 12 R1,215/month
Effective tax rate R14,580 ÷ R180,000 8.1%
Example 2: R30,000/month (R360,000/year) — middle income
Step Calculation Amount
Annual taxable income R30,000 × 12 R360,000
Tax on first R245,100 18% × R245,100 R44,118
Tax on R114,900 (R245,101–R360,000) 26% × R114,900 R29,874
Total before rebate R73,992
Less: Primary rebate (R17,820)
Annual income tax R56,172
Monthly tax (PAYE) R56,172 ÷ 12 R4,681/month
Effective tax rate R56,172 ÷ R360,000 15.6%
Example 3: R50,000/month (R600,000/year) — upper-middle income
Step Calculation Amount
Annual taxable income R50,000 × 12 R600,000
Tax on first R245,100 18% R44,118
Tax on R138,000 (to R383,100) 26% R35,880
Tax on R147,100 (to R530,200) 31% R45,601
Tax on R69,800 (to R600,000) 36% R25,128
Total before rebate R150,727
Less: Primary rebate (R17,820)
Annual income tax R132,907
Monthly tax (PAYE) R132,907 ÷ 12 R11,076/month
Effective tax rate R132,907 ÷ R600,000 22.2%
Example 4: R100,000/month (R1,200,000/year) — high income
Step Calculation Amount
Annual taxable income R100,000 × 12 R1,200,000
Tax on first R245,100 18% R44,118
Tax on next R138,000 26% R35,880
Tax on next R147,100 31% R45,601
Tax on next R165,600 36% R59,616
Tax on next R191,200 39% R74,568
Tax on next R312,900 (to R1,200,000) 41% R128,289
Total before rebate R388,072
Less: Primary rebate (R17,820)
Annual income tax R370,252
Monthly tax (PAYE) R370,252 ÷ 12 R30,854/month
Effective tax rate R370,252 ÷ R1,200,000 30.9%
These examples assume no retirement fund contributions, no medical aid, and no other deductions. Your actual PAYE will differ if you contribute to a pension/RA fund or have a medical aid — both of which reduce taxable income and therefore reduce tax. Use our calculator for a personalised estimate.

Medical scheme fees tax credit — reduces your tax directly

Beyond the age rebates, taxpayers with a medical aid can also claim the medical scheme fees tax credit (Section 6A), which reduces your actual tax liability — not your taxable income.

2026/2027 monthly medical credit:

Beneficiaries Monthly credit
Taxpayer (member) R376
First additional dependant R376
Each further dependant R254
Source: SARS Budget 2026 FAQ — sars.gov.za
How it works: If you pay for yourself and one dependant on medical aid, you receive R376 × 2 = R752/month credit = R9,024/year deducted directly from your income tax bill.
Using the R30,000/month example (R360,000/year taxable income):
  • Income tax before medical credit: R56,172
  • Medical credit (self + 1 dependant): R9,024/year
  • Income tax after medical credit: R47,148 (effective rate drops to 13.1%)

How 2026/2027 brackets compare to 2025/2026

The tax rates themselves are unchanged — 18% through 45% across seven brackets. What changed is that all bracket thresholds, rebates, and tax-free thresholds increased by 3.4% to partially compensate for inflation — the first such adjustment since the 2023/24 tax year.
Taxable income bracket 2025/2026 rate 2026/2027 rate Change

Bracket creep: The 3.4% bracket adjustment is a partial inflation relief. If your salary increased by more than 3.4% in 2026, the excess increase pushes a larger portion of your income into higher brackets — a phenomenon called bracket creep. Average South African salary increases in 2026 were 5–6%, meaning most employees experienced some bracket creep despite the adjustment. (Source: SARS Budget 2026 FAQ)

Your marginal rate is NOT your effective rate. Even if you are "in the 36% bracket", your effective tax rate will be significantly lower — because the 36% rate only applies to the portion of income within that bracket, not your full salary.

Frequently Asked Questions

For the 2026/2027 tax year (1 March 2026 – 28 February 2027), South Africa has seven income tax brackets: 18% on taxable income up to R245,100; 26% on R245,101–R383,100; 31% on R383,101–R530,200; 36% on R530,201–R695,800; 39% on R695,801–R887,000; 41% on R887,001–R1,878,600; and 45% on income above R1,878,600. All bracket thresholds were adjusted 3.4% for inflation — the first adjustment since 2023/24.
For the 2026/2027 tax year, you pay zero income tax if your annual taxable income is below: R99,000 (if under 65); R153,250 (if aged 65 to 74); R171,300 (if aged 75 or older). These thresholds exist because the primary rebate (R17,820) exactly offsets the 18% tax on income up to R99,000.
No. South Africa uses a progressive tax system — you only pay each rate on the portion of income that falls within that bracket. For example, if you earn R400,000 per year, you pay 18% on the first R245,100, 26% on the next R138,000, and 31% only on the remaining R16,900 — not 31% on the full R400,000. Your effective tax rate is always lower than your bracket rate.
The primary rebate for 2026/2027 is R17,820 — increased from R17,235 in 2025/2026. The primary rebate applies to all individual taxpayers under 65 and is deducted directly from your calculated income tax (not from your taxable income). The secondary rebate (age 65–74) is R9,765 and the tertiary rebate (age 75+) is R3,249.
The tax rates themselves (18%–45%) are unchanged. All seven bracket thresholds were increased by 3.4% for inflation — the first inflationary adjustment since the 2023/24 tax year. This means taxpayers who received salary increases of up to 3.4% will not be pushed into higher brackets. Rebates and tax-free thresholds also increased by 3.4%, resulting in approximately R585 per year in additional relief for taxpayers under 65.
The maximum marginal income tax rate in South Africa is 45%, which applies to taxable income above R1,878,600 per year (R156,550/month) for the 2026/2027 tax year. However, even at this income level, the effective tax rate is lower than 45% — because all income below the bracket threshold is taxed at lower rates.
