Understanding PAYE in South Africa
PAYE (Pay As You Earn) is the mechanism SARS uses to collect income tax from salaried employees on a monthly basis. Rather than requiring you to pay a large lump sum at the end of the tax year, your employer calculates and deducts your income tax each month, then pays it directly to SARS on your behalf. This system ensures that most salaried South Africans never face a surprise tax bill at year-end.
Understanding exactly how your PAYE is calculated helps you make better financial decisions, from evaluating job offers to planning for bonuses and salary increases. This comprehensive guide explains every component of the PAYE calculation using the official SARS 2027 tax year tables effective from 1 March 2026 to 28 February 2027.
How PAYE is calculated step-by-step
Your monthly PAYE deduction follows a specific sequence defined by SARS. Here's the exact calculation your payroll department performs each month:
Step 1: Determine your annual taxable income
Your monthly salary is multiplied by 12 to get your annual gross income. If you entered an annual figure, that number is used directly. This becomes your starting point for the tax calculation.
Step 2: Apply SARS tax brackets
Your annual income is then applied against South Africa's progressive tax brackets. For the 2027 tax year, the brackets are:
- First R245,100: 18%
- R245,101 – R383,100: 26%
- R383,101 – R530,200: 31%
- R530,201 – R695,800: 36%
- R695,801 – R887,000: 39%
- R887,001 – R1,878,600: 41%
- Above R1,878,600: 45%
Step 3: Subtract rebates
After calculating the raw tax amount from the brackets, SARS subtracts rebates directly from your tax bill. These are fixed rand amounts, not percentages:
- Primary rebate: R17,820 for all taxpayers under 65
- Secondary rebate: Additional R9,765 for ages 65-74
- Tertiary rebate: Additional R3,249 for ages 75+
The primary rebate of R17,820 creates the tax-free threshold. Since 18% of R99,000 equals R17,820, anyone earning under R99,000 annually pays zero income tax.
Step 4: Subtract medical aid credits
If you're on a registered medical aid scheme, SARS provides tax credits that reduce your PAYE directly:
- R376 per month for the main member (taxpayer)
- R376 per month for the first dependent
- R254 per month for each additional dependent
For a family of four on medical aid, this equals R1,360 per month (R16,320 per year) in direct tax savings.
Step 5: Divide by 12 for monthly PAYE
The final annual tax amount is divided by 12 to determine your monthly PAYE deduction. This is the amount that appears on your payslip each month.
Calculating PAYE on R30,000 per month
Let's walk through a realistic scenario: monthly salary of R30,000 (R360,000 annually), under 65, with medical aid for yourself and one dependent.
Tax calculation:
- Annual salary: R360,000
- Tax on R360,000 = R44,118 + 26% of (R360,000 - R245,100) = R44,118 + R29,874 = R73,992
- Less primary rebate: R17,820
- Less medical credit (2 members × R376 × 12): R9,024
- Annual PAYE: R47,148
- Monthly PAYE: R3,929
Your effective tax rate is 13.1% of your gross salary. You pay R3,929 per month in income tax to SARS.
Common PAYE amounts by salary level
The table below shows monthly PAYE calculations for common salary levels in South Africa. These figures assume a single taxpayer under 65 with no medical aid contributions.
| Monthly Salary | Annual Salary | Monthly PAYE | Effective Rate |
|---|---|---|---|
| R8,250 | R99,000 | R0 | 0% |
| R10,000 | R120,000 | R315 | 3.2% |
| R15,000 | R180,000 | R1,215 | 8.1% |
| R20,000 | R240,000 | R2,115 | 10.6% |
| R25,000 | R300,000 | R3,381 | 13.5% |
| R30,000 | R360,000 | R4,330 | 14.4% |
| R40,000 | R480,000 | R6,003 | 15.0% |
| R50,000 | R600,000 | R8,058 | 16.1% |
| R65,000 | R780,000 | R11,627 | 17.9% |
| R85,000 | R1,020,000 | R16,456 | 19.4% |
| R100,000 | R1,200,000 | R20,018 | 20.0% |
Note: These figures assume no medical aid contributions. Adding medical aid credits would reduce these PAYE amounts.
Why your PAYE is not simply "your bracket rate times salary"
One of the most common misconceptions about South African tax is that if you fall into, say, the 26% bracket, all your income is taxed at 26%. This is completely wrong and leads to significant misunderstanding about how raises and bonuses affect your take-home pay.
In reality, South Africa uses a progressive tax system where only the portion of income within each bracket is taxed at that rate. If you earn R400,000 per year:
- The first R245,100 is taxed at 18% = R44,118
- The next R138,000 (R245,101 to R383,100) is taxed at 26% = R35,880
- The final R16,900 (R383,101 to R400,000) is taxed at 31% = R5,239
- Total tax before rebates: R85,237
This is why moving into a higher tax bracket does not reduce your overall take-home pay the way people sometimes fear. You only pay the higher rate on the income above the threshold, not on your entire salary.
The critical role of rebates in reducing your tax bill
After the bracket calculation produces a theoretical tax amount, SARS rebates are subtracted directly — not as a percentage reduction, but as a fixed rand amount that everyone in that age category receives. This is why very low earners often pay no tax at all: their theoretical tax liability falls below the rebate amount entirely.
| Age Category | 2027 Tax Year Rebate | Combined Total |
|---|---|---|
| Under 65 | R17,820 | R17,820 |
| 65 to 74 | R9,765 additional | R27,585 |
| 75 and over | R3,249 additional | R30,834 |
The primary rebate of R17,820 is what creates the tax-free threshold of R99,000. Since 18% of R99,000 equals R17,820, the rebate exactly cancels out the tax on the first R99,000 of income.
Why medical aid changes your PAYE
Medical aid contributions generate a monthly tax credit that reduces your PAYE directly. This is separate from any pre-tax deduction structure your employer might use. The medical aid tax credit is one of the more overlooked ways medical aid membership affects your actual take-home pay beyond the visible premium deduction.
For the 2027 tax year, the credits are:
- Main member: R376 per month (R4,512 per year)
- First dependent: R376 per month (R4,512 per year)
- Each additional dependent: R254 per month (R3,048 per year)
A family of four on medical aid receives R1,360 per month (R16,320 per year) in direct tax savings. This credit is applied after the rebate calculation and reduces your final PAYE amount.
Strategies to legally reduce your PAYE
While you cannot avoid paying tax entirely, there are several legal strategies to reduce your PAYE burden:
Contribute to a Retirement Annuity
Contributions up to 27.5% of your income (capped at R430,000/year) reduce your taxable income before PAYE is calculated. This is the most powerful tax reduction strategy available.
Join or Upgrade Medical Aid
Each medical aid member qualifies for R376/month tax credit. For a family of four, this saves R1,360/month directly off your PAYE bill.
Claim Allowable Deductions
Home office expenses, professional body fees, work-related travel, and donations to registered PBOs all reduce your taxable income when you file your tax return.
Time Bonus Payments Strategically
If close to a bracket threshold, ask your employer to defer your bonus to the next tax year (after 1 March) to stay in a lower bracket.
Understanding your effective tax rate
Your effective tax rate is the percentage of your gross salary that goes to income tax. It's calculated as: (Annual PAYE ÷ Annual Gross Salary) × 100.
Due to rebates and the progressive nature of the tax system, your effective rate is always lower than your marginal rate (the rate on your top rand of income). For example, someone earning R480,000 per year has a marginal rate of 31% but an effective rate of only 15.0%.
This distinction is crucial when evaluating job offers or salary increases. A R50,000 raise when you're in the 31% bracket doesn't mean you lose 31% of the raise to tax — you only lose 31% of that specific R50,000, while your existing salary continues to be taxed at the lower rates that applied to it.
Why your payslip PAYE might differ from this calculator
This calculator provides an accurate estimate based on standard SARS rules, but your actual payslip PAYE might differ slightly for several reasons:
- Retirement annuity contributions: If you contribute to an RA or company pension fund, this reduces your taxable income and therefore your PAYE.
- Travel allowance: Only 80% of a travel allowance is taxable, which affects the calculation.
- Employer medical aid contributions: If your employer pays part of your medical aid, this affects the credit calculation.
- Timing differences: If you started work mid-month or had unpaid leave, your payroll system annualizes differently.
- Tax directives: For large bonuses or lump sums, SARS may issue a specific tax directive with different rates.

Frequently asked questions
How is PAYE calculated in South Africa?
PAYE is calculated by applying the SARS tax brackets to your annual income, subtracting the primary rebate of R17,820 and any medical aid credits, then dividing by 12 for the monthly amount. Your employer performs this calculation automatically each month.
How much is PAYE on R30,000 per month?
On R30,000 per month (R360,000 per year), PAYE is approximately R4,330 per month after the primary rebate, based on the SARS 2027 tax year. This assumes no medical aid credits. With medical aid for yourself and one dependent, it would be approximately R3,929 per month.
What is the difference between PAYE and income tax?
There is no difference — PAYE (Pay As You Earn) is simply the mechanism SARS uses to collect income tax monthly from salaried employees. It's the same tax, just collected differently than for freelancers or business owners who pay provisional tax.
Does PAYE include UIF?
No. PAYE is income tax only. UIF (Unemployment Insurance Fund) is a separate 1% deduction capped at R177.12 per month. Your payslip shows both as separate line items.
Can I reduce my PAYE legally?
Yes. Contributing to a retirement annuity (up to 27.5% of income, max R430,000/year) reduces your taxable income. Joining a medical aid gives you R376/month tax credit per member. Both strategies legally reduce your PAYE.
Why is my PAYE higher than I expected?
Common reasons include: you're in a higher tax bracket than you realized, you don't have medical aid credits reducing your tax, you received a bonus that was taxed at your marginal rate, or you have additional income sources that increased your total taxable income.
What happens if my employer deducts too much PAYE?
If your employer over-deducts PAYE, you'll receive a refund when you file your annual tax return with SARS. The refund is typically paid within 21-45 business days of submitting your return.
How do age rebates work?
South Africa provides additional tax rebates for older taxpayers: R9,765 extra for ages 65-74, and R3,249 extra for ages 75+. These are added to the standard R17,820 primary rebate and reduce your tax bill directly.
