What is Form W-4?

All of your employees are required to complete Form W-4 as part of their onboarding and new hire process. IRS Form W-4 is used to determine the correct amount of federal income tax that must be withheld from their pay.

It is a good idea to have your employees complete a new form each year, especially when their financial or personal situations change. It is also important that all of the information is correct because if the right amount is not withheld the employee may owe the IRS back taxes.

What The New Form W-4 Means For Employees?

Late tax filing

The Tax Cuts and Jobs Act made several sweeping changes regarding both personal and dependent exemptions and enhancements to the child tax credit. These changes will go into effect next year during the 2018 tax season.

The following groups should check their withholding status and provide updates:

  • 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.
Other complicated financial situations should also revise their current W-4. Click here to review Form W-4 changes.
