Year-End Bonuses, 13th Cheques and PAYE: Getting Payroll Ready for the 2026 Festive Season Crunch

Every December, South African payroll administrators face the same squeeze: shortened banking weeks, staff leave requests piling up, and the added complexity of taxing bonuses correctly. With the 2026/2027 tax year now in effect, it's worth getting ahead of the festive season payroll crunch rather than scrambling in the second week of December.

Why Bonuses Aren't Taxed "Separately"

A common misconception among small business owners is that a bonus or 13th cheque is taxed at a flat, special rate. It isn't. SARS doesn't have a separate "bonus tax" — instead, the bonus is added to the employee's normal monthly income, and PAYE is recalculated on the combined total using the 2026/2027 tax tables.

In practice, this usually means:

• The employee's salary plus bonus is annualised (or the bonus is treated as part of that month's income).
• Tax is calculated on this higher total.
• The primary (and secondary/tertiary, where applicable) rebate is subtracted.
• Any medical scheme fee tax credits are applied.
• The result gives that month's PAYE — which will almost always be higher than a normal month because the employee has effectively moved into a higher marginal tax bracket for that pay period.

This is why employees are often surprised that their "bonus take-home" is noticeably less than the gross figure. It's not an error — it's simply how marginal tax rates work when a lump sum lands in a single month.

A Quick Way to Estimate the Extra PAYE

If you want a sanity check before processing bonuses, the logic bookkeepers use is:

1. Calculate PAYE on the employee's annual salary excluding the bonus.
2. Calculate PAYE on the annual salary including the bonus.
3. The difference between the two is the additional PAYE attributable to the bonus.

This method avoids confusion and gives employees a clearer picture than simply applying a flat percentage, which can under- or overstate the deduction.

Retirement Annuity Contributions Can Soften the Blow

For employees who contribute (or want to contribute) to a retirement annuity, timing matters. Contributions made before the bonus is processed can reduce taxable income for that month, within SARS's limit of 27.5% of taxable income, capped at R350,000 per year. This won't eliminate PAYE on a bonus, but it can meaningfully reduce it — worth flagging to staff who ask about "reducing bonus tax" each year.

Building a Festive Season Payroll Checklist

To avoid the usual December scramble, consider locking in these steps by mid-November:

• Confirm bonus policy and amounts — fixed 13th cheque, discretionary bonus, or performance-based? Get sign-off from management early.
• Finalise your payroll run dates — December often has an earlier cut-off due to bank holidays and reduced processing days.
• Reconcile leave balances — festive leave payouts or accruals often get bundled with bonus runs, so check these don't get missed.
• Update UIF and SDL calculations — bonuses form part of remuneration for UIF purposes, so make sure contributions reflect the increased monthly figure.
• Communicate with staff early — a short note explaining why bonus PAYE is higher than expected avoids a flood of queries on payday.
• Keep clean records — accurate payroll figures now make your 2026 tax year reconciliation and EMP501 submission far smoother.

Where One Practice Fits In

Getting the numbers right before payroll runs is half the battle. One Practice helps small businesses and bookkeepers organise payroll figures, track bonus calculations, and keep records audit-ready — so when it's time to capture everything for submission, the figures are accurate and easy to work with. We prepare and organise the numbers; you or your registered tax practitioner remain responsible for the actual capture and submission to SARS.

Plan Early, Avoid the December Rush

The festive season is stressful enough without a payroll fire drill. By understanding how bonus PAYE actually works, communicating clearly with staff, and locking in your processing calendar early, you'll head into December with far less admin anxiety — and your team gets paid correctly and on time.
