<prompt> Human: My Wife quit her job to become a Stay at home mom, she had total wages of 15,151.31 with a Federal withheld of 1,279.47. I brought in a total of 121,296.42 with a Federal withholding of 19,500.11.When I plug in her numbers into TurboTax it drops our refund almost about 3000. I was told she was getting taxed based on my income rate?I tried running the numbers Married Filled separate, however we cannot write off her Student loan interest. Both filing statuses we cannot take advantage of the Child credit or credit for our medical bills which is fine. Should she still be taxed at my rate only bringing in so little?  <response>: There is no his or her rate. All the income is combined and taxed at the same rate.
