Handling Bonuses and Arrears in FBR-Compliant Payroll

Bonuses, arrears, and other one-off payments are taxable as part of salary, but they cause the same problem in payroll every time: 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 simplest way 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 extra tax across the remaining pay periods. That way no single month takes a big unexpected deduction, and the year-end total still comes out right. Arrears for an earlier period need to be assigned to that period, or the annual figures will not 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 tax over remaining periods where it makes sense
• 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 as soon as 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.
