<prompt> Human: What should he do now?He entered each W2 separately on TurboTax and each came back with saying hed get about 1000 back. After combining them, hes getting 100 back from Federal and will end up owing for State. So what happened? He accidentally claimed 2 on one of them, but Im assuming its too late to do anything about that. Combined jobs, he made roughly 33,000 so I dont think it has anything to do with his tax bracket but I could be wrong. Any explanation would be helpful.  <response>: ExampleJob 1: 16500 income, 1523 withholding, taxable income 16500 6300 4000 6200; income tax 623, so phantom refund of 900. That would be considered in the 10 marginal tax bracket.Job 2: same as Job 1. Also a phantom refund of 900.Combined: 33000 income, 3046 withholding, taxable income 33000 6300 4000 22700; income tax 2948, so 98 refund is the true final situation.I know you mentioned he used different W-4 allowances settings, and its unlikely he earned same amount in both jobs or had same withholding in both jobs. But the same principal is at work when you use his actual numbers.The real culprit here is that the standard deduction of 6300 and the personal exemption of 4000 dont get doubled if you have two jobs. And the size of the tax brackets doesnt double if you have two jobs. This actually means that the combined income gets taxed partly in 10 bracket and partly in 15 bracket.If bf was really two separate people each with their own deduction and exemption, each of those people would get a 900 refund. But since hes actually just one person with two jobs, more of the income is subject to taxes because he only has one standard deduction and personal exemption.
