Handling Bonuses and Arrears in FBR-Compliant Payroll
Bonuses, arrears, and other one-off payments are taxable as part of salary, but they create a recurring problem in payroll: because they raise annual taxable income, they can push an employee into a higher marginal slab and change the tax due not just on the bonus itself but on the projection for the rest of the year.
The Correct Treatment
The cleanest approach is to add the bonus or arrears to the employee's projected annual taxable income, recompute the full-year tax using the FBR slabs, and then spread the additional liability across the remaining pay periods. This avoids deducting an unexpectedly large amount in a single month while ensuring the year-end total is correct. Arrears relating to a prior period require careful attribution so the annual figures reconcile.
What to Get Right
- Add one-off payments to annual taxable income before recomputing tax
- Recalculate the slab in case the payment crosses a threshold
- Spread the extra liability over remaining periods where appropriate
- Attribute arrears to the correct period for clean reconciliation
- Show the bonus, its tax effect, and the adjustment on the payslip
Zaffre HRM, the payroll module within Zaffre Axon by Zaffre Tech, recomputes the annual projection the moment a bonus or arrears entry is added, applies the correct slab, and adjusts the remaining months so the employee is neither over-deducted in one shot nor under-withheld by year-end.
