1. The Short Answer

Your payslip shows one month: what you earned, what was deducted and what reached your bank account. Your IRP5 is the tax certificate your employer issues after the tax year ends (the year runs 1 March to 28 February). It adds up the whole year under numbered source codes, and SARS uses it to assess your tax return.

If the IRP5 is wrong, your assessment is wrong. Ten minutes checking it against your last payslip of the year is the cheapest tax check you can do.

2. The Lines on Your Payslip

Earnings

Deductions

Employer contributions

Many payslips also list what the employer paid: its UIF share, the Skills Development Levy (1% of payroll, paid by employers with a payroll above R500,000 a year) and its pension and medical contributions. SDL and the employer's UIF are not taken from your pay.

3. Worked Example: a R35,000 Salary

Ayanda is 34 and earns R35,000 a month. She contributes 7.5% to her employer's pension fund and pays R4,000 a month for medical aid for herself and her partner. Here is her 2026/2027 payslip, using SARS's annualised method:

LineMonthlyHow it is worked out
Basic salaryR35,000.00
Pension fund (7.5%)−R2,625.007.5% × R35,000
PAYE−R4,569.00See below
UIF (1%, capped)−R177.121% × R17,712
Medical aid−R4,000.00
Net payR23,628.88

The PAYE works like this:

  1. Annual salary: R35,000 × 12 = R420,000
  2. Less pension contributions: R2,625 × 12 = R31,500, leaving taxable income of R388,500
  3. Tax on R388,500 from the 2026/2027 table: R79,998 + 31% of the amount above R383,100 = R81,672
  4. Less the primary rebate of R17,820 = R63,852 a year, or R5,321 a month
  5. Less the medical scheme fees credit for two people: R376 + R376 = R752 a month
  6. PAYE: R5,321 − R752 = R4,569

Payroll systems round slightly differently, so your own payslip may differ by a few rand. Our PAYE calculator runs the same steps on your numbers.

4. What the IRP5 Is

The IRP5 (or IT3(a) if no tax was deducted) is issued by every employer you worked for during the tax year. Each employer submits its copy to SARS, which is how SARS can pre-populate your return and auto-assess many taxpayers. In the 2026 filing season, SARS ran auto-assessments from 1 to 12 July 2026; the deadline for non-provisional taxpayers who were not auto-assessed was 23 October 2026, and provisional taxpayers have until 22 January 2027.

You can download your IRP5 from eFiling or the SARS MobiApp, or ask your employer's payroll department for a copy.

5. The IRP5 Source Codes That Matter

Every amount on the IRP5 sits next to a four-digit source code. Codes starting with 3 are income; codes starting with 4 are deductions, contributions and tax. These are the ones most employees see:

CodeWhat it is
3601Salary: your taxable income from employment for the year
3605Annual payment, such as a bonus or 13th cheque
3701Travel allowance
3810Medical aid fringe benefit (the employer's share of your contributions)
3699Gross remuneration: the total of your taxable income codes
4001Your pension fund contributions
4005Total medical aid contributions (yours plus your employer's)
4102PAYE: total income tax deducted for the year
4116Medical scheme fees tax credit your employer already gave you
4141UIF contributions
4142Skills Development Levy (employer)
4149Total of PAYE, SDL and UIF
4474The employer's medical aid contribution

You do not need to understand every code. The important ones are 3601 (did they get your income right?), 4102 (how much tax was paid?) and the medical and retirement codes, because those drive your credits and deductions.

6. Checking Your IRP5 Before You File

  1. Compare 3601 with your February payslip. Most payslips show year-to-date totals. The IRP5 salary should match the year-to-date taxable pay.
  2. Compare 4102 with the year-to-date PAYE on the same payslip.
  3. Check the tax year and your details: ID number, name and income tax number. A wrong ID number means SARS may never link the IRP5 to you.
  4. Check the period of employment. If you joined mid-year, the dates should match your start date.
  5. If you had two employers, make sure both IRP5s appear on your return. Two employers each deducting PAYE as if they were your only income is the most common reason for a surprise tax bill, because neither applies the higher brackets your combined income reaches.
Why two jobs often mean a bill: each employer gives you the full R17,820 primary rebate and taxes you from the lowest bracket. SARS gives you the rebate only once and taxes your combined income, so the PAYE withheld is too low. Expect to pay the difference on assessment.

7. If Something Is Wrong

You cannot correct an IRP5 yourself. Only your employer can, by submitting a corrected certificate to SARS. Ask payroll in writing, and keep a copy of the request.

Frequently Asked Questions

What is the maximum UIF deduction in South Africa?

R177.12 a month. UIF is 1% of pay, but only on earnings up to R17,712 a month. Your employer pays the same amount again.

What does code 3601 mean on an IRP5?

Code 3601 is your taxable salary from employment for the tax year. It should match the year-to-date taxable pay on your last payslip of the year.

What is code 4102 on an IRP5?

Code 4102 is the total PAYE (employees' tax) your employer deducted and paid to SARS for the year.

Can I fix a mistake on my IRP5 myself?

No. Only your employer can issue a corrected IRP5 to SARS. Ask payroll in writing, then file or correct your return once it is fixed.

Why do I owe SARS when PAYE was deducted every month?

The most common reason is having two employers in the same year. Each one deducts PAYE as if it is your only income, so the higher brackets on your combined income are never applied until you file.
