2017-2018 Tax Notice

As a result of the Tax Cuts and Jobs Act of 2017 the IRS has changed income tax tables, as well as the withholding rate for employees. This may significantly reduce your tax return or cause you to be under withheld for the year. The IRS has released a withholding calculator you can use to see how these changes impact you. You will need a copy of your 2017 return, your latest paycheck, and any information about deductions or credits you expect to take.

Exemption from Federal Tax Withholding

Not everyone can claim exemption from federal income tax withholding. Employees must meet specific qualifications to be exempt. Employees can claim exemption if both of the following situations apply:

  1. In the previous year, the employee had the right to a refund of ALL federal income tax withheld from their wages because they had no tax liability.
  2. In the current year, the employee expects a refund of ALL federal income tax withheld because they plan to have no tax liability.

There are also some other factors that help decide if an employee can be exempt from federal income taxes. For help determining if you are exempt from taxes, refer to IRS Publication 505.

Those employees who claim exempt must submit a new Form W-4 by February 15 each year if they wish to claim exempt for the current tax year. If the employee does not submit a new form by that date, Payroll will withhold at the single filing status with no allowances.

NOTE: Please remember you can update your Form W-4 online in Patriot Web Self Service.
