Commission Tax South Africa 2026: PAYE, UIF, SDL

Commission Tax South Africa 2026: What Every Payroll Manager Gets Wrong

Commission taxation in South Africa confuses almost everyone — sales managers, reps, and even some payroll administrators. The rules aren't complex once you understand the mechanics, but the variability of commission income creates genuine complexity that catches companies out at year-end reconciliation.

This guide covers how PAYE, UIF, and SDL apply to commission income for the 2026 tax year (1 March 2025 – 28 February 2026), with a worked example so you can see the numbers in action.

How PAYE on Commission Actually Works

The most important thing to understand: PAYE is calculated on a cumulative basis across the tax year. SARS doesn't want you to apply a flat monthly rate — you're supposed to project the year's earnings and calculate tax accordingly each month.

Here's the process your payroll system should follow each month:

1. Add up all remuneration received so far in the tax year (including all previous months' salary and commission)
2. Add the current month's earnings (salary + commission)
3. Project this cumulative figure to an annualised amount
4. Apply the tax tables to get annual tax liability
5. Subtract tax already paid in prior months
6. The remainder is the current month's PAYE deduction

This cumulative approach means a rep who earns very little commission in April and May, then a large commission in June, will have a big PAYE deduction in June — the system is "catching up" on the lower deductions from the earlier months.

The Variability Problem

Because commission fluctuates month to month, reps often experience:

• Low PAYE months: When commission is small, the projected annual income looks modest, and PAYE is low
• High PAYE months: A big commission month triggers a large catch-up deduction
• Year-end surprises: If cumulative PAYE deductions don't match actual tax liability, the rep either owes SARS or receives a refund at assessment

This isn't a mistake — it's how the system is designed. The cumulative method ensures that, by year-end, the total PAYE deducted approximates the actual annual tax liability.

SARS 2025/2026 Tax Brackets

For the tax year ending 28 February 2026:

The primary rebate is R17,235 per year, and the tax threshold (under 65) is R95,750 per year — meaning no tax is payable on income below this level.

Worked Example: R15,000 Salary + R20,000 Commission

Let's work through a single month. Assume:

• Monthly salary: R15,000
• Commission earned this month: R20,000
• Total gross this month: R35,000
• This is month 6 of the tax year, and previous months averaged R18,000 gross

Step 1: Year-to-date gross earnings Months 1–5 at R18,000 each = R90,000 Month 6: R35,000 YTD total = R125,000

Step 2: Annualise R125,000 ÷ 6 × 12 = R250,000 projected annual income

Step 3: Calculate annual tax on R250,000

• Tax on R237,100 at 18% = R42,678
• Tax on R12,900 (R250,000 – R237,100) at 26% = R3,354
• Gross annual tax = R46,032
• Less primary rebate: R17,235
• Net annual tax = R28,797

Step 4: Monthly tax = R28,797 ÷ 12 = R2,400

Step 5: Calculate tax already paid If months 1–5 averaged R18,000 gross (annualised R216,000 — below the R237,100 bracket), PAYE was modest, say approximately R600/month × 5 = R3,000 paid so far.

Step 6: PAYE for month 6 Tax payable to date (6 months): R28,797 ÷ 12 × 6 = R14,399 Less tax already paid: R3,000 PAYE deduction month 6: R11,399

That's a significant deduction on a R35,000 gross month — and exactly why reps with variable commission often feel the PAYE on a big month seems disproportionate.

UIF on Commission Income

Yes, UIF applies to commission income. The Unemployment Insurance Fund contribution is:

• Employee: 1% of gross remuneration
• Employer: 1% of gross remuneration
• Monthly ceiling: Contributions are capped at the monthly UIF ceiling (approximately R17,712/month as of 2024 — confirm the current figure with the Department of Employment and Labour)

For our example rep earning R35,000 in month 6:

• Employee UIF: R177.12 (at the ceiling)
• Employer UIF: R177.12

Commission is included in "remuneration" for UIF purposes. If the rep earns no commission in a particular month, UIF is calculated only on the base salary.

SDL: Skills Development Levy

SDL is an employer-only obligation — the rep does not contribute. The rate is 1% of total monthly leviable payroll.

For companies with an annual payroll below R500,000, SDL is exempt. Above this threshold, it applies to all employees.

SDL is calculated on total leviable payroll, which includes salary and commission. So in a month where your entire sales team earns high commissions, your SDL liability increases proportionally.

IRP5 Source Codes: Why 3606 Matters

At year-end, commission income must be reported on the IRP5 under source code 3606 (commission and bonus income). Base salary is reported under 3601.

Why does this matter?

• SARS uses source codes to cross-reference income types
• A rep submitting their ITR12 needs the codes to match what SARS expects
• Incorrectly coding commission as salary (3601) can trigger SARS queries and delays
• For reps who also do tax directive applications, the source code affects how the directive is calculated

Ensure your payroll system correctly separates salary from commission on every payslip and on the IRP5 at year-end.

The Self-Employed vs Employed Rep Distinction

Some companies pay reps as independent contractors (self-employed) rather than employees. The tax treatment differs significantly:

Employed rep (PAYE):

• Employer deducts PAYE monthly
• UIF and SDL apply
• IRP5 issued at year-end
• Rep may need to submit an ITR12 but PAYE is already withheld

Independent contractor (not PAYE):

• No PAYE deduction — rep must register for provisional tax
• No UIF (contractor is not "employed")
• Contractor submits IRP6 (provisional tax returns) twice a year
• Commissioner may reclassify contractor as employee if the arrangement looks like employment — SARS has specific tests for this

If your rep works exclusively for your company, uses your equipment, and works set hours, SARS may view them as an employee regardless of what the contract says. This is a compliance risk worth reviewing with your tax advisor.

Tax Directive Applications

Reps with highly variable income can apply to SARS for a tax directive — an instruction to the employer specifying an alternative PAYE rate. This is useful when the standard cumulative method consistently produces over-deductions or under-deductions.

The rep applies on eFiling (form IRP3(a)) and SARS issues a directive specifying a fixed percentage to use. The employer applies this rate instead of the standard tables.

Year-End Reconciliation

At tax year-end, the employer submits an EMP501 reconciliation to SARS. This reconciles:

• Total PAYE deducted across the year
• PAYE declared on monthly EMP201 returns
• IRP5 values for each employee

Where there are discrepancies — often caused by commission volatility or corrections to commission calculations mid-year — the reconciliation must be adjusted. Errors here cause SARS assessments against the company.

Common reconciliation problems caused by commission:

• Commission paid in the wrong month (shifted by a day into the next EMP201 period)
• Commission reversed and re-paid (creates negative values in one period)
• Commission paid as "advance" before it's earned (timing mismatches)

What Happens If Commission Isn't Run Through Payroll

A common mistake: paying commission as a separate EFT outside the payroll system — perhaps as a "bonus" or "incentive" through the business account.

The consequences:

• PAYE is not deducted — the company becomes liable for the unpaid PAYE
• No UIF or SDL contributions
• No IRP5 reporting — SARS won't see the income on the rep's record
• The rep may face a large assessment when they submit their ITR12 and declare the income

SARS has access to banking data through third-party data submissions. Undeclared commission payments are increasingly likely to be identified during automated reconciliation.

The Bottom Line

Commission taxation in South Africa is manageable if your payroll processes are set up correctly. The key principles:

1. PAYE uses the cumulative method — variable income means variable monthly deductions
2. UIF applies to commission, capped at the monthly ceiling
3. SDL is an employer obligation on total payroll including commission
4. Use IRP5 source code 3606 for commission income
5. Run all commission through payroll — never pay it as an off-payroll EFT
6. Consider tax directives for reps with highly variable earnings

Getting the mechanics right from the start saves significant remediation work at year-end — and keeps both the company and your reps on the right side of SARS.
