IRS Releases Revised Form W4 for 2018

March 01, 2018

IRS issued a revision to the Form W4, Employee’s Withholding Allowance Certificate. The new form reflects changes required by the Tax Cuts and Job Act of 2017.

2018 W4 Form

The IRS has issued a highly anticipated revision to the Form W4, Employee’s Withholding Allowance Certificate. The new form reflects changes required by the Tax Cuts and Job Act of 2017 signed by President Trump last December. The changes to the form are primarily reflected in the personal allowances worksheet (on page 3 of Form W4) used by employees to determine the number of allowances an employee should claim from withholding.

Below is an illustration of the changes between the 2017 form and updated 2018 revision.

The major changes to the worksheet reflect required updates to income thresholds for the Child Tax Credit as well as additional steps to determine how to adjust dependent exemptions based on projected annual income.

The IRS plans to release a new version of Form W4 for 2019 that will contain further changes involving withholding.

Withholding Calculatory for Taxpayers 

The IRS has also issued an updated Withholding Calculator employees may use to determine if adjustments are needed to their Form W4.  The Withholding Calculator is located here:

The IRS encourages all employees to use the Withholding Calculator to perform a “paycheck checkup”.  As with any major changes to tax law, the IRS encourages employees to check their paychecks and review their Form W4 to determine if any changes are necessary due to the Tax Cuts and Job Act of 2017.

“Withholding issues can be complicated, and the calculator is designed to help employees make changes based on their personal financial situation,taking a few minutes can help taxpayers ensure they don’t have too little – or too much – withheld from their paycheck.”

David Kautter, Acting IRS Commissioner

The IRS recommends the following groups check their withholding:

  •  Two-income families
  •  People with two or more jobs at the same time or who only work for part of the year
  •  People with children who claim credits such as the Child Tax Credit
  •  People who itemized deductions in 2017
  •  People with high incomes and more complex tax returns

In addition to these tools, the IRS has issued a list of Frequently Asked Questions for employers and employees who may have questions about the new Form W4 and accompanying Withholding Calculator.  We have incorporated these Frequently Asked Questions into a FAQ document which will be available in tandem with this alert.

The new 2018 Form W4 will be available within Web Pay in the coming weeks; should you require a copy of the form earlier, a PDF version of the form is available here: W-4.pdf
