“The Internal Revenue Service is replacing its old online tax withholding calculator with a new Tax Withholding Estimator that it says will make it easier for taxpayers to determine how much in taxes they should withhold from their paychecks next year.
The move comes after widespread complaints from many taxpayers this year that they ended up unexpectedly owing taxes to the IRS after passage of the Tax Cuts and Jobs Act at the end of 2017. In many cases, the problem stemmed from taxpayers not adjusting the withholding for their paychecks because the tax overhaul eliminated the traditional personal and dependent exemptions. The IRS had publicized the need last year to go online and do a “paycheck checkup” using the online tax withholding calculator to adjust their withholding, but the process was cumbersome and confusing, and relatively few taxpayers followed the IRS’s advice.” ~Michael Cohn, Accounting Today
