Paycheck Calculator Download

The federal Tax Cuts and Jobs Act of 2017 revised income tax brackets for 2018.  California government employees who withhold federal income tax from wages will see these changes reflected in 2018 payroll.  The Paycheck Calculator below allows employees to see how these changes affect pay and withholding.  If you would like to update your withholding, contact your Human Resources office.   

If you have Microsoft Excel or a spreadsheet software application that can read an XLS file, you can download a spreadsheet that will do paycheck calculations. This may be useful if you are considering changing your federal or state tax withholding, deferred compensation, or tax-sheltered annuity amounts.                       

If you have difficulty viewing the input calculation screen, press and hold the "Ctrl" key then tap the F10 key to maximize the viewing screen.  For a full-screen view of the Excel file, double-click the title bar area.  

The calculators allow employees to calculate paychecks for monthly, semi-monthly and bi-weekly in one place, which also can be used for out-of-state employees with no state taxes (input “99” in the Additional Exemptions State field).  There are two paycheck calculators that compute paychecks for employees in Illinois and New York.
