Flat vs. Aggregate Method

Most employers use the flat 22% supplemental rate for bonuses under $1M. The aggregate method combines your bonus with your regular pay to calculate withholding based on your actual tax bracket. Your actual tax liability is determined when you file your return — these are withholding estimates only.
