Formula

taxableBonus = Math.max(0, bonusAmount - exemptLimit); tax = taxOnSlabs(taxableBonus); netBonus = bonusAmount - tax

How the calculation works

The calculator first subtracts any exempt limit from the bonus amount to find the part that is actually taxable.

It then applies the individual income tax slabs, taxing each slice of the taxable amount at its own rate from zero up to the highest slab reached.

The total of those slices is the tax, and subtracting it from the bonus gives the net amount received.

Common mistakes

When to use it

Worked example

With a bonus of 500000 taka and no exempt limit, the first 350000 taka is free of tax, the next 100000 taka is taxed at 5 percent and the next 50000 taka at 10 percent, so the tax is 10000 taka and the net bonus is 490000 taka.

Taxable bonus ৳500,000.00
Tax ৳62,500.00
Net bonus ৳437,500.00

Common questions

Is a festival bonus taxable?

Yes, a bonus is treated as part of your income for the year, so it is taxed under the same individual slabs as your regular salary.
