In 2018 I filed Form 4868 for an extension, but have not filed anything since. I am looking to get caught up and have a question on filing status. My girlfriend and I live in Colorado, and beginning in 2010 we started filing as Married filing jointly. For 2018 and moving forward I would like to go back to filing individually, but not sure which status to use. We have never been officially married, but have a daughter together and all of our finances are handled jointly up to now. I am debating between Single, Head of Household, or Married filing separately. My girlfriend is a W2 employee and I am self-employed, so in addition to filing separately for personal reasons I am looking for the best direction tax wise. Any advice is appreciated, thank you.
