Frequently Asked Questions
Why is a bonus taxed at a high rate?
A bonus is added on top of your salary, so it is taxed at your highest slab or bracket. The tax shown is the extra tax caused by the bonus.
Does the result include tax?
Only the tax-based calculators do. The pay conversion tools work on gross pay unless the page says otherwise.
Can I use this for part-time pay?
Yes. Set the hours per week and paid weeks to match your schedule.
Can I change the inputs and recalculate?
Yes. Change any value and press Calculate. The result, the table and the explanation update straight away.
Note
Tax results are estimates for a salaried individual using the current published rates and standard allowances. Real tax depends on your full circumstances, so confirm with the tax authority or a qualified adviser.
