<prompt> Human: I receive an hourly wage and a monthly commission. The hourly wage is paid weekly and the commission is paid monthly. The commission and hourly wage are lumped into one paycheck at the end of the month.I make around 50k a year with my hourly. I make about 5k a month with my commission. At the end of every month for the past year - my commission checks have been heavily taxed about 43. My payroll company says its because it looks like Im making 6k a week and that it is a combination of a fixed supplemental rate and a time based rate taxes as if I was receiving this every week.My question is - what can I do if anything to reverse the high taxes and keep it at the standard 25 tax rate? If that is not an option - how can I process my commission checks differently to avoid the high tax rate?  <response>: you are not paying higher taxes. rather, you have overpaid tax, and over payments are refundable. taxes are done at an annual rate, and all in one bucket on earned income. when you calculate taxes only on a single payment, it gets multiplied by 12 if its monthly, and then thats the rate thats applied. so the calculation is correct for the single payment, but probably not for your individual circumstance for the whole year. 25 might not be correct either see the link provided by the bot on tax brackets.payroll companies dont have any way to know your individual circumstances, so its not really in their interest to find out what your annual income is that would be your accountant. for instance, you might have a second job. nevermind capital investments.you have two choices. either calculate your annual rate yourself including bonuses, find out how much you will be owed back, and tell the payroll company adjust it, or wait to the end of the year and get a refund.if you have more bonuses coming, and are not sure what theyll be, and tax calculations arent your thing, you may be better off leaving it to the end.
