IR-2019-03, January 16, 2019

WASHINGTON — The Internal Revenue Service announced today that it is waiving the estimated tax penalty for many taxpayers whose 2018 federal income tax withholding and estimated tax payments fell short of their total tax liability for the year.

The IRS is generally waiving the penalty for any taxpayer who paid at least 85 percent of their total tax liability during the year through federal income tax withholding, quarterly estimated tax payments or a combination of the two. The usual percentage threshold is 90 percent to avoid a penalty.

This relief is designed to help taxpayers who were unable to properly adjust their withholding and estimated tax payments to reflect an array of changes under the Tax Cuts and Jobs Act (TCJA), the far-reaching tax reform law enacted in December 2017.

“We realize there were many changes that affected people last year, and this penalty waiver will help taxpayers who inadvertently didn’t have enough tax withheld,” said IRS Commissioner Chuck Rettig. “We urge people to check their withholding again this year to make sure they are having the right amount of tax withheld for 2019.”

IRS has an online calculator to assist taxpayers in filling out their W-4 withholding forms.
