<prompt> Human: Quick question for the gurus.My salary gets taxed at 32.9 all in. I work in sales, and my commissions get taxed much higher than that at 43.9?!?Why is this?EDIT: Awesome comments all around. Very enlightening! Thanks all!  <response>: uVoerendaalse is correct, I just want to emphasize one point - your commission checks arent getting taxed at a higher rate, theyre just having taxes withheld at a higher rate. At the end of the year youre going to get a W-2 that will show all the money youve earned all year, and there will be no difference between salary wages and commission wages. Its all taxed the same. The reason more taxes are withheld from the commission checks is as the other commenter described - your checks are effectively annualized when determining how much tax to withhold. So if you get a 1,000 biweekly salary check, that check has taxes withheld as if you make 26,000 a year. If you get a 8,000 monthly commission check, that check has taxes withheld as if you make 96,000 a year.
