Using The Tax Calculator
To start using The Tax Calculator, simply enter your annual salary in the “Salary” field in the left-hand table above. If you know your tax code you can enter it, or else leave it blank.
If you do any overtime, enter the number of hours you do each month and the rate you get paid at – for example, if you did 10 extra hours each month at time-and-a-half, you would enter “10 @ 1.5”. 5 hours double time would be “5 @ 2”. The Fair Labor Standards Act requires that all non-exempt employees are paid overtime rates of at least one and a half times normal wage for any work over 40 hours per week.
Select your filing status from the drop-down. Choose whether you are filing as an individual (“Single”), as a married couple filing a joint return, as a married individual filing separately from your spouse, or as the head of household.
Choose the number of dependents you have, excluding yourself and your spouse, who are already included in the default standard deduction. If you have any other deductions (such as contributions to a retirement plan) enter the monthly amount into the deductions field.
