Tax Reform and Your Paycheck

As a result of the changes made by the tax reform legislation (Tax Cuts and Jobs Act) signed into law on December 22, 2017, the IRS recently updated its income tax withholding tables for 2018. The new tables reflect the increase in the standard deduction, repeal of personal exemptions and changes in tax rates and brackets. As a result of the tax reform legislation, the federal supplemental wage rate for 2018 has been decreased to 22 percent (previous rate was 25 percent).

The 2018 withholding tables have been updated in HRMS and all employee paychecks issued as of January 18, 2018 will be calculated based on the updated tables. 

The new withholding tables are designed to work with the Forms W-4, Employee’s Withholding Allowance Certificate, that employees already have in place. If you need to review or update your tax withholding information, please log into HRMS and select: Main Menu>Self Service>Payroll and Compensation>W-4 Tax Information. For now, employees will not have to change existing Forms W-4 unless they have had a change in personal or financial situation in 2018. Please make sure you select the “Submit” button at the bottom of the page if you are changing your withholding information.

To help you determine your required withholding, the IRS is revising the withholding tax calculator on its website (available at The IRS anticipates this calculator will be available by the end of February. Employees are encouraged to use the calculator to adjust their withholding once it is released. The IRS advises that employees use the calculator, to update their withholding in response to the new law or changes in their personal circumstances in 2018. Please consult your personal tax advisor for any questions.

The IRS does not plan on releasing a redesigned Form W-4, which will reflect the revised tax rules, until the end of 2018. 

Payroll is responsible for providing accurate and timely paychecks to all University faculty, staff and students. Additionally, we assure that Federal, State and Social Security withholdings are accurately remitted to various government agencies, and that W-2 statements are issued annually.

Payroll is located in the Medical Center Room # 1-7220, just around the corner from the Miner Library.
