Is a retention bonus taxable and when is PAYE withheld?

Direct answer
SARS lists a bonus or incentive paid to retain an employee's services for a specified period as an annual payment. PAYE on an annual payment is calculated by taking the annual equivalent of remuneration for the tax period, adding the annual payment and calculating the difference in tax. SARS says the amount is reflected under code 3605 on the IRP5 or IT3(a).
If the employee must repay the incentive after leaving before the end of the contract period, SARS says the employees' tax already paid may not be refunded to the employee.
What this means in practice
A retention bonus is not simply extra monthly salary. SARS includes a bonus or incentive to retain an employee for a specified period among its examples of annual payments. This is why the payroll deduction may look different from an ordinary salary-only payslip.
The annual-payment calculation considers the annual equivalent of remuneration earned in the tax period and adds the annual payment to that figure. The employees' tax deducted is the difference between the tax on the combined result and the tax on the annual equivalent. This explains the method, but it is not a flat percentage rate that can be applied without payroll facts.
The payment agreement remains important. It should show the amount, payment date, retention period and what happens if employment ends early. SARS's current guide is clear on one PAYE point: where the retention amount is repayable by the employee on early termination before the contract period ends, the employees' tax paid on that amount may not be refunded to the employee.
Step-by-step
- Read the retention agreement.
Identify the amount, period of required service, date of payment and repayment clause. Keep the signed agreement rather than relying on a verbal explanation.
- Review the payslip when the amount is paid.
Check that the bonus amount and PAYE deducted are shown. Ask payroll for an explanation if the payslip does not clearly identify the payment.
- Ask how payroll applied the annual-payment method.
Payroll can explain how it classified the payment and which certificate code it expects to use. Keep its response with the agreement and payslip.
- Check the IRP5 or IT3(a).
When the certificate is available, review code 3605 and the payment amount against your records. If the certificate is wrong, ask the employer to investigate and correct its certificate submission to SARS.
- Keep repayment evidence if employment ends early.
If a repayment condition is triggered, retain the agreement, employer demand and proof of any amount repaid. Do not expect payroll to refund the employees' tax already paid simply because the incentive is repayable.
- Review the annual assessment.
Keep the ITR12 and ITA34 after filing. If the certificate or assessment does not reconcile with the records, obtain tailored help before taking further action.
Documents and records to keep
- Signed retention agreement.
- Payslip showing the payment and PAYE.
- Payroll calculation explanation.
- IRP5 or IT3(a) certificate.
- Repayment request and proof of repayment, if applicable.
- ITR12 and ITA34 assessment.
Important limits and exceptions
The article addresses a retention incentive paid for a specified service period. It does not decide whether a contract creates a valid civil repayment obligation. That is a separate employment-contract question.
Do not use a generic percentage rate for PAYE on a retention payment. SARS's annual-payment calculation depends on remuneration for the tax period and the annual payment itself.
The no-refund statement is limited to the employees' tax paid on an incentive that is repayable after early termination before the contract period ends. It should not be extended to every payroll correction or repayment arrangement.
When to get tailored advice
Get tailored help if the agreement covers several years, payment is split, a repayment is disputed, the employer has withheld an amount that cannot be explained, or the IRP5 code is inconsistent with the records. Help is also useful before you assume a repayment has no further tax consequences.
TaxProof can help organise the agreement, payroll documents, certificate and repayment evidence. The employer applies PAYE in payroll, and SARS processes the final tax assessment.
