important tax, legal questions for those seperated

[theotherhalf]

My H and I have been physically seperated since 8/07. He lives in a rental house in town and our girls and I live on our farm. Last year we filed taxes as if everything was still the same. We continue to share one bank account only. He writes the checks for his rent, utilities, bike payment, and his misc stuff. I write all the checks for the bills here and farm stuff, Nothing is seperated finacially or legally. H used his address when purchasing a bike so the bike pymt stuff goes there, and it was licensed in that county so now all vehicles in his name are registered in that county and have his address. Otherwise everything else says he lives here.

My questions are.
Those of you seperated at least a year, do you file taxes as M, or do you LBS file as head of house hold? Does your WS use his/her physical address or your address? Can we get into trouble with him using two addresses?

Any tips/warnings/ or advice???

the year stbxd left he lived elsewhere and had another address, by mutual consent we filed M to get more money back, the IRS didn't care, for all they know he was at address due to work or illness or what have you, we never had to explain anything.
If you are in good terms and agree to split (hopefully) the money you get back there shouldnt' be a problem about filing just the way you always did.

thanks cat, and that's the way we did it last year.
Does anybody know if there is any problem in him using 2 different addressess?
