<prompt> Human: Husband started his own business in 2010, sole proprietorship. We also got married that year and had decided to do joint returns stupid me!. He opened up a business checking account but doesnt have enough self-control to not use it for personal expenses. For 2012, Ive changed my filing status so at least I can file for this year. Still cant file for previous 2 years because husband cant get his shit together. I dont know where to start with getting his financials together. I have to do it or it will never get done I have log-ins for his accounts including his invoice website. Note, his business checking account has been closed.Dumb question: Can I file 2010-2011 as single even though filing status was married?? Can they just incorporate how much tax I would have owed? I found a great tax person and am ready to get back on track, just need to know what to bring her. Any advice would be greatly appreciated!!TL:DR Lazy husband screwed me on our tax returns and now I havent filed for the last 2 years.  <response>: You cannot file 2010 and 2011 as single. You can file MFS, though. Keep in mind that you will be hit with penalties and interest for not filing your returns on time and potentially underwithholding. Your husband has probably not sent in estimated tax payments and he probably has not paid his self-employment taxes either, so youll be hit with penalties and interest on those as well. You and your husband need to have a sit down and hash out finances. Not filing returns on time throws away money because of penalties and interest and there is no reason that should ever happen.Plus, your husband didnt screw you on your tax returns. You are a grown woman and need to take equal responsibility for not getting the returns filed in time. You know well in advance that tax season is coming and should have plenty of time to gather the necessary information. EDIT: As for what to bring the tax preparer --W-2s from 2010 and 2011, any 1099s you received during those years, along with information on itemized deductions if you have enough to itemize property taxes paid, medical expenses paid, sales tax or state income taxes, mortgage interest, etc.
