The new tax tables have been released and offer employees a good opportunity to review your W-4.
But exercise patience: The IRS is revising form W-4, though a release date is not yet available. “The Internal Revenue Service (IRS) has updated the income-tax withholding tables for 2018 to reflect changes made by the new tax law. The updated tables reflect the new rates for employers to use during the 2018 tax year. “
PLEASE NOTE: The tax tables on IRS.GOV haven’t yet been updated.
Employers are instructed to use the 2018 withholding tables as soon as possible, but not later than February 15, 2018.
