<prompt> Human: I am a teacher, and in my school district our salary is divided equally into 20 paychecks. Often teachers have the opportunity to earn additional income through working the after-school program, by being on the Child Study Team, or other various extra jobs. Sometimes this extra pay is added into our regular paychecks as Extra Compensation and sometimes its given as its own separate check. This seems to change randomly, we never know how well get the extra money.Teachers in the district always complain that when the money is added into our regular check, more taxes are taken out than if its issued as a separate check. Everyone thinks this. It doesnt sound right to me, but I dont know enough about how taxes work to dispute it.Is this really a thing? Does one large paycheck get taxed more heavily than two smaller ones? Keep in mind, were not talking enormous sums of money here - the extra pay per pay period is never more than a few hundred dollars.  <response>: If you get one larger cheque whatever software thinks you make that amount of money all the time and it probably bumped you up into a higher tax bracket.If you get paid in two smaller cheques from different organizations that dont share payroll departments, they dont bump you up to the next tax bracket, but now you risk under-paying on your taxes.It really doesnt matter. At the end of the tax year, it will all even out and either youll get a bigger refund if you got more taxes taken out than you should have or youll owe more money if not enough taxes got taken out because you got multiple cheques.
