How Colorado taxes bonuses
Colorado withholds a flat 4.4% state income tax on bonuses, on top of the federal 22%.
Federal withholding is the same in every state. Most employers take a flat 22% of the bonus (37% on supplemental pay over $1,000,000 in a year). Social Security takes 6.2% up to the yearly wage base and Medicare 1.45%. If your employer adds the bonus to a regular $2,500 paycheck instead, the aggregate method withholds about $1,150.54 of federal tax on a $5,000 bonus, against $1,100.00 with the flat rate.
Colorado also takes CO FAMLI paid leave from a bonus, the same as from any wages: $22.00 on $5,000.
