<prompt> Human: My wife and I got married last year and filed jointly. And I guess her parents didnt file their taxes for last year and are just now doing it. For whatever reason they will have to pay 6,000 unless we amend our taxes so they can claim her. What are the consequences to us if we do this?  <response>: Do not let this set a precedent that will haunt you and your wife for your entire marriage.Tying yourself up money-wise to your in-laws and letting them dictate the decisions you make only enables them to step all over you. You both need to stand firm against their interference into your personal finances, taxes, etc.
