Is 13th-Month Pay Taxable? How the Shared PHP 90,000 Ceiling Works

Identify which benefits share the ceiling

Start with a payroll summary of your 13th-month pay and other benefits included in the same annual exemption pool. Ask which bonuses or benefits your employer has allocated to it and which amounts were already paid. Do not assume that every allowance belongs in this pool or that every payment described as a bonus is automatically exempt.

Qualified de minimis benefits have their own category limits. BIR RR 29-2025 changed several of those limits, including amounts for rice subsidy, clothing and medical assistance. Under BIR guidance, amounts exceeding a de minimis limit may affect the shared benefit pool. Payroll must classify the benefit and track the applicable annual, semester or monthly limit.

• Check the revised benefit-specific limits

Work out the remaining exemption

For the 13th-month calculation, subtract other covered benefits from PHP 90,000, stopping at zero. Compare the remaining amount with the 13th-month pay. The smaller figure is the exempt part of that pay. The rest is its taxable portion.

This allocation is a way to check the 13th-month component. It does not erase tax already due on earlier benefits, and it does not calculate your final annual income tax. Enter the other covered benefits for the same calendar year and avoid counting the 13th-month amount in both inputs.

• Check the exemption in the 13th-month calculator

Example 1: a smaller 13th-month payment can still be partly taxable

Suppose 13th-month pay is PHP 30,000 and other covered benefits total PHP 70,000. The shared pool is PHP 100,000. Other benefits leave PHP 20,000 of the exemption available: PHP 90,000 minus PHP 70,000.

Of the PHP 30,000 13th-month amount, PHP 20,000 fits within the remaining ceiling and PHP 10,000 is taxable compensation. The fact that the 13th-month payment alone is below PHP 90,000 does not exempt the entire payment.

Example 2: the shared ceiling is already exhausted

Suppose the other covered benefits already total PHP 100,000 and 13th-month pay is PHP 50,000. The remaining exemption is zero, so all PHP 50,000 of that 13th-month payment is taxable compensation.

The earlier benefits also exceed the ceiling by PHP 10,000. That is a separate taxable component in this example. A calculator output labeled “taxable 13th-month portion” should show PHP 50,000, not silently present it as the total taxable excess across every benefit paid during the year.

Taxable pay is different from tax withheld

A PHP 10,000 taxable portion does not mean PHP 10,000 tax is due. It means that amount belongs in the compensation subject to the applicable tax computation. Your employer considers the relevant payroll and tax adjustments; the exemption check alone cannot determine the final withholding amount.

Do not apply a withholding bracket to the bonus alone and assume it settles your year-end tax. If you use the withholding calculator, supply the correct taxable compensation for the selected pay period and confirm the basis with payroll. A final annual reconciliation may differ from a simple per-period planning estimate.

• Check the BIR payroll tables

What to ask payroll when the figures are unclear

Request the calendar-year covered-benefit total before this payment, the exempt part allocated to 13th-month pay, and the taxable excess included in compensation. If a de minimis item affects the pool, ask which category limit was applied and whether an earlier payment used part of it.

If you do not yet know other covered benefits, an entry of zero is only a scenario, not a verified exemption. Keep the statutory-pay estimate separate, save the assumptions you used, and update the taxability check when payroll confirms the annual figures.
