This week’s question comes from Madeleine, an executive. I’ve averaged about 30% of my pay going toward federal income tax withholding each pay period. This week I had 35% of my pay withheld from my bonus for federal income tax. Why did my federal income tax withholding increase? Answer: In TD 9276, the IRS promulgated regulations covering supplemental wage payments paid by a single employer (or group of employers under common control) that exceeded $1,000,000 to a single employee in a calendar year. The American Jobs Creation Act of 2004 (Public Law 108-357) requires that withholding from such wages be at a flat rate of 35%. The regulations provide rules for determining whether wages should be considered regular wages or supplemental wages for withholding purposes.
