Frequently Asked Questions
Common questions about the free online income tax calculator.
Each rate applies only to the part of your income inside its own bracket, so a higher rate
never applies to everything you earn.
The marginal rate is charged on your last slice of income, so it is the rate of the bracket
your highest earnings fall into.
It is total tax divided by total income, which is always lower than the marginal rate when
more than one bracket applies.
Yes. Every upper limit and rate in the table is editable, so you can match the rules of any
country, region or tax year.

adds the results to give the total tax.
Net pay is your income after the calculated income tax only, so other deductions such as
pension or insurance are not included.
No bracket holds a taxable amount, the total tax stays at zero and the effective rate is
reported as zero percent.

to a server.
