<prompt> Human: We make similar amounts of money. I will have considerable student loan interest to deduct. He wont. Because of employer matching were doing all our 401K funding through my company. Were both maxing out Roth IRAs. Any guidance into which direction makes more sense for us? Are there other major considerations?Come January Ill run the numbers both ways, but if there are things we should adjust now Id rather be prepared. EDIT: Sounds like filing jointly makes the most sense. Ill still confirm before we file, but thanks for the info.  <response>: You cant deduct student loan interest if you file MFS. Source: Im a CPA
