<prompt> Human: Hi guys first time on this bad boy, but I read it everyday! Id really appreciate some input.Background: - Filing single and live in MO- Currently in sales. I have a very flexible job, where I can make as much or as little as I want to an extent.- Grossed 40,330.48 since 1115 through 5292015 5 months. - Ive net 26,890.54 - Will invest 5,500 into Roth-IRA doubt this is relevantSituation:At the current rate of income, I will make around 97,000 for 2015. With that being said, sales obviously has some variables, but, in OCT and NOV I expect to make around 12,000 each month compared to my average 8,000. So I will more than likely come out over 100K.My question:Should I try and make just under 90,750 to remain in the 3rd tax bracket, or make a little more and hit the 4th tax bracket percentages below? I mean, lets just say I make 90,751 this year and get taxed at 28 rather than the 25 if I was to make 90,750... Id pay more in taxes and essentially make less than if I grossed the lesser amount right? So what is the number that I have to gross in order for the 28 tax rate to make sense over the 25 tax? Im probably making this way more complicated than need be, but what is that magic number I need to hit? Thanks peeps! I really appreciate the help!2015 tax brackets for taxes due April 15, 2016Single Filer 2537,451 to 90,7502890,751 to 189,300  <response>: Should I try and make just under 90,750 to remain in the 3rd tax bracket, or make a little more and hit the 4th tax bracket percentages below?Instead of trying to limit your income to stay in a particular tax bracket, you should learn about how federal taxation works and understand that federal tax brackets are marginal.If you make 90,751, you still take home more money after taxes than if you make 90,750.
