The Internal Revenue Service this week released an updated withholding calculator and a new version of Form W-4. The calculator and new W-4 can be used to ensure 2018 individual tax withholding amounts are accurate in light of the recent tax law changes.

The Tax Cuts and Jobs Act made changes to the tax law, including increasing the standard deduction, removing personal exemptions, increasing the child tax credit, limiting or discontinuing certain deductions and changing the tax rates and brackets.

If changes to withholding should be made, the Withholding Calculator gives employees the information they need to fill out a new Form W-4, Employee’s Withholding Allowance Certificate. Employees will submit the completed W-4 to their employer.
