<prompt> Human: My wife and i got married last fall and when tax season came around I ended up filing my taxes separately first. She filed after me and was unable to deduct interest paid on her student loans due to my salary. This introduced about a 600 swing in her return compared to last year Did we mess up in filing separately? Is there anyway to fix the issue even after everything was submitted?  <response>: If you filed separately your income should not matter to her deductions.
