WASHINGTON — The Internal Revenue Service today released Notice 1036, which updates the income-tax withholding tables for 2018 reflecting changes made by the tax reform legislation enacted last month. This is the first in a series of steps that IRS will take to help improve the accuracy of withholding following major changes made by the new tax law.

The updated withholding information, posted today on IRS.gov, shows the new rates for employers to use during 2018. Employers should begin using the 2018 withholding tables as soon as possible, but not later than Feb. 15, 2018. They should continue to use the 2017 withholding tables until implementing the 2018 withholding tables.

Many employees will begin to see increases in their paychecks to reflect the new law in February. The time it will take for employees to see the changes in their paychecks will vary depending on how quickly the new tables are implemented by their employers and how often they are paid — generally weekly, biweekly or monthly.

The new withholding tables are designed to work with the Forms W-4 that workers have already filed with their employers to claim withholding allowances. This will minimize burden on taxpayers and employers. Employees do not have to do anything at this time.

“The IRS appreciates the help from the payroll community working with us on these important changes,” said Acting IRS Commissioner David Kautter. “Payroll withholding can be complicated, and the needs of taxpayers vary based on their personal financial situation. In the weeks ahead, the IRS will be providing more information to help people understand and review these changes."
In addition, the IRS will help educate taxpayers about the new withholding guidelines and the calculator. The effort will be designed to help workers ensure that they are not having too much or too little withholding taken out of their pay.

The new law makes a number of changes for 2018 that affect individual taxpayers. The new tables reflect the increase in the standard deduction, repeal of personal exemptions and changes in tax rates and brackets.

For people with simpler tax situations, the new tables are designed to produce the correct amount of tax withholding. The revisions are also aimed at avoiding over- and under-withholding of tax as much as possible.
To help people determine their withholding, the IRS is revising the withholding tax calculator on IRS.gov. The IRS anticipates this calculator should be available by the end of February. Taxpayers are encouraged to use the calculator to adjust their withholding once it is released.
