I live in a community property state, so husband and I file our taxes as two schedule C's, split in half with profits and expenses from our shared business. Since we share the business 50/50, I've followed instructions of creating one schedule C that reflects everything from the entire business and then splitting everything down the middle and going back and creating a schedule C for each of us, with each having half of the earnings, expenses, etc. But I'm not sure what to do with a SEP contribution I made last year? I put $600 into a SEP account that I have as sole owner. So I'm thinking that I can't really put half under his name (i.e. give him credit for making a $300 SEP contribution and me credit for a $300 SEP contribution), since that account is in no way associated with his SSN and his name isn't anywhere on it. But then if I put the entire $600 under my schedule C that reflects half of everything else for the two of us, is that going to be a problem that I didn't split that one line item 50/50?
