What this means for you
You are encouraged to reassess your tax situation and submit a new federal W-4 for the 2024 tax year. You are not required to submit a new federal Form W-4. If you do not furnish a new federal Form W-4, your tax withholding will continue based on the information on your existing federal W-4; however, the withholding will be based on the new 2024 federal tax chart, which means actual federal tax withheld may change. Note that special rules apply to federal Forms W-4 claiming exemption from withholding.
