If my spouse and I file jointly, live separately, and both claim home office expenses for our separate businesses, which home address should I use on our tax return?

We live in separate apartments one block away from each other. We each have a self-employment business. We each claim home-office expenses. It seems like we can list only one home address on our tax return. If the other person claims home office expenses at an address that isn't reported as their home address, will that cause any problems?

Make sure that each business has its own separate Form 8829 and there is no crossover. You have to go through all the screens and say that person one is done, done, done before starting the second Schedule C. Yes, use separate addresses on your Schedule Cs.
