Why Does Payroll PCB Differ from Annual Tax?

PCB spreads an estimate of annual tax across months. Your final tax uses actual income, reliefs, and rebates for the year — so refunds or balances are normal.

Different inputs

Payroll may not know all reliefs, bonuses timing, or other income.

Reliefs change the outcome

Lifestyle, medical, EPF relief caps and rebates appear fully at filing.

Bonus months spike MTD

High bonus months raise that month PCB even if average monthly tax is lower.

Keep CP22 updated

Updating expected reliefs with HR can align PCB closer to final tax.
