The IRS released the 2018 W-4 and withholding calculators on Feb. 28. This was later than usual, as adjustments were required following the Tax Cuts and Jobs Act 2017鈥檚 passage in December. Employee Services encourages all employees to review their 2018 W-4 and to use the IRS withholding calculator.
2018 W-4
The W-4 allows employees to determine the amount of federal income tax withheld from their pay.
Employee Services recommends all University of Colorado employees check their W-4 in the employee portal and make any needed adjustments鈥攅specially if an employee got married, had a child or experienced other changes that would affect their tax status.
Please note, any changes made to the federal W-4 in the portal will be mirrored in an employee鈥檚 Colorado state withholdings, as Colorado instructs employers to base state withholdings on the federal form.

Before using the calculator, the IRS recommends gathering recent pay stubs, 2017 income tax return and W-2s.
