The Internal Revenue Service today, March 22, 2019, provided
additional expanded penalty relief to taxpayers whose 2018 federal
income tax withholding and estimated tax payments fell short of their
total tax liability for the year.
The IRS is lowering to 80 percent the threshold required to qualify for this relief. Under the relief originally announced Jan. 16, the threshold was 85 percent. The usual percentage threshold is 90 percent to avoid a penalty.
