<prompt> Human: My spouse would like for us to file jointly it puts us in a lower tax bracket but does not want to show me any of the information they entered into the tax preparation software or the prepared version of the forms. I feel that this is somewhat sketchy, and that the signature line requires each person to read the entire form. Is this a common or at all acceptable practice for when spouses dont want to share all their financial details with each other?Assistant: I know its been said here over and over, but this is well beyond finances.So, the personal finance answer: Dont sign anything you dont have knowledge of.The relationship side note: You, me, and everyone else knows your spouse is hiding something major. Like, kids from another relationship major.Human: I actually think its extremely unlikely that what they changed is major or even that interesting. I do know that it reduced our net refund by about 1k. I think its more of a stubbornness thing, perhaps on both our parts. Assistant: ... Then why tell us? Or, more to the point, if this sort of financial secrecy is normal in your relationship, why start worrying now? The rest of this conversation really isnt for this sub. Human: Weve been fortunate in that we normally dont discuss finances, and it largely hasnt been an issue. This came up because if we dont file jointly it kicks us up into a higher tax bracket, and it would reduce our refund by 4k. You are correct in that the larger issue here is probably off-topic for this sub.  <response>: Weve been fortunate in that we normally dont discuss finances, and it largely hasnt been an issue.From the sounds of it, you two dont discuss anything. You SHOULD be discussing finances with someone who is your spousewife. You should absolutely know what theyre doingwhere theyre getting their income from. Hopefully you guys can sit in a room together and communicate verbally to each other what needs to be discussed.
