<prompt> Human: As the title suggests, I am unofficially separated from my wife we havent gone through the proper legal channels to file for divorce just yet. We have spoken about how we plan on filing our taxes. We both recognize that since we are still legally married, it would make the most sense to file jointly. But, from my understanding, there isnt really any way to figure out how much of the return is attributed to each spouse. Does anyone know of a way to figure out how much we each should be getting back from the lump sum return? Otherwise, we will have to file separately and not get back as much money.Thanks!  <response>: What was your total tax liability? Compare that to withholding from each of your jobs. Then return it proportionally based on that.Example: Youre getting a 1000 return, you owed 9K total, your job withheld 4000 and hers withheld 6000, so she paid 60 of what was paid in and gets back 60 of the return, or 600.
