Taxes and Payroll

Use this calculator to help you determine the impact of changing your payroll deductions. You can enter your current payroll information and deductions, and then compare them to your proposed deductions. Try changing your withholdings, filing status or retirement savings and let the payroll deduction calculator show you the impact on your take home pay.
Pay period
This is how often you are paid. Your selections are: Weekly (52 paychecks per year) , Every other week (26 paychecks per year), Twice a month (24 paychecks per year), Monthly (12 paychecks per year), Annually (One paycheck per year). The default is Biweekly.
Gross pay
This is your gross pay, before any deductions, for the pay period. Please enter a dollar amount from $1 to $1,000,000.
Filing status
This is your income tax filing status. The choices are "Single" and "Married". Choose "Married" if you are married or file as "head of household". Choose "Single" if you file your taxes as a single person or if you are married but file separately.
Number of allowances
When your Federal income tax withholdings are calculated, you are allowed to claim allowances to reduce the amount of the Federal income tax withholding. For 2012, each allowance you claim is equal to $3,800 of income that you expect to have in deductions when you file your annual tax return. The number of allowances you should claim depends largely on the number of dependents you have and your itemized deductions. This calculator allows from 0 to 99 allowances.
457 plan withholding
This is the percent of your gross income you put into a taxable deferred retirement account such as a 457. While increasing your retirement account savings does lower your take home pay, it also lowers your Federal income tax withholdings. The impact on your paycheck might be less than you think. While your plan may not have a deferral percentage limit, this calculator limits deferrals to 80% to account for FICA (social security and medicare) taxes. Please note that your 457 plan contributions may be limited to less than 80% of your income. Check with your plan administrator for details.
Post-tax deductions
Enter any payroll deductions made by your employer that are made with after tax income.
Post-tax reimbursements
Enter any reimbursements made by your employer that are after tax.
FICA OASDI
FICA Old Age Survivors and Disability Insurance. For 2012, FICA OASDI is calculated as your gross earnings times 4.2%. This is a reduction from 6.2%, which will return in 2013. Please note that this calculator does not make any assumptions as to the total FICA OASDI paid for the current year. For 2012, incomes over $110,100 that have already had the maximum FICA OASDI amount of $4624.20 withheld will not have additional FICA OASDI withholdings.
FICA Medicare
FICA Medicare is calculated as the gross earnings times 1.45%. Unlike FICA OASDI, there is no annual limit to FICA Medicare deductions.
Federal tax withholding calculations
Federal income tax withholdings were calculated by:
  1. Multiplying taxable gross wages by the number of pay periods per year to compute your annual wage.
  2. Subtracting the value of allowances allowed (for 2012, this is $3,800 multiplied by withholding allowances claimed).
  3. Determining your annual tax by using the tables below (single and married rates, respectively).
  4. Dividing the amount of tax by the number of pay periods per year to arrive at the amount of federal withholding tax to be deducted per pay period.
