<prompt> Human: For the past year I would pay all the bills rent, utils, CC etc and my wife would write me a check for half. She would pay her car payment and personal CC bill out of her checking and Id do the same.Now after a year of marriage, I think we are going to combine. Reasons being, shes a teacher and doesnt get paid in the summer, so Ill be taking care of mostly everything anyway.Also, I have a CC that nets 2 cash back and I figure we might as well take advantage of that and use it for everything instead of our separate cards that dont have as high of a in rewards.Any reasons NOT to combine? I know these situations are different for everyone, and the splitting has worked fine for us for years, but I feel like putting everything into one pot might just simplify things.  <response>: I know people have differing perspectives on this, but I think joining forces financially is the best move if you want to maximize wealth in the long-run.But since you asked for reasons NOT to combine:1. Are either of you unable to restrain yourself when it comes to spending? Combining money is a good idea, but not if its going to lead to fighting. If you dont see eye to eye on spending, this is something to consider.2. Assets and tax implications - Do either of you own anything substantial? Maybe a house or a business? If so, depending on where you live, there might be tax implications. Speak to an accountant.
