Workers will see changes in their February paychecks once employers adopt the new guidance, the news release said.
Notice 1036 is "the first in a series of steps that the IRS will take to help improve the accuracy of withholding following major changes made by the new tax law", the agency said.
But for many taxpayers, they will need to assess whether the new tables really are withholding enough money so that they're not saddled with a big bill when they file their taxes next year.
Congressional Democrats are concerned that in making those changes, the IRS may have caved to pressure from the administration to deliver immediate tax savings to workers' paychecks while exposing taxpayers to higher tax bills in 2019.
The government said that workers will not have to fill out new W-4 forms to take advantage of the changes this year. They also said they will be updating the withholding calculator by the end of February to help you adjust your withholding. "Taxpayers can not make these changes until the revised Form W-4 is published, which the IRS has announced will be forthcoming in the coming months".
The new withholding tables take into account a variety of changes brought about by the passage of the GOP's revamped tax code. Form W-4 and the revised calculator will reflect additional changes in the new law, such as changes in available itemized deductions, increases in the child tax credit, the new dependent credit and repeal of dependent exemptions.

Notice 1036 also said that employers could withhold on supplemental wages of up to $1 million at a flat rate of 22 percent.
A backup withholding rate of 24 percent applies to non-employee compensation when individuals fail to provide proper tax identification information, the IRS said. President Donald Trump and the Republican architects of the tax plan have deflected criticism of the unpopular legislation, insisting at every turn that Americans will come to love the new law when they see their heftier paychecks next month - with less money withheld in anticipation of lower income taxes.
