IRS Releases Updated Form W-4 and Withholding Calculator
The IRS has released a new version of Form W-4 and a revised Withholding Calculator on irs.gov (IR-2018-36). These updated tools can help you check your 2018 tax withholding to determine if it's still appropriate following passage of the Tax Cuts and Jobs Act in December 2017. The IRS urges taxpayers to use these tools to make sure they have the right amount of tax withheld from their paychecks, taking into account significant changes to the tax law for 2018.
