Yes you should start a new account to file separately, BUT your spouse cannot file as Head of Household if you are living together. It is usually always better to file as married filing joint if you are together.
To qualify for the head of household filing status while married, you must be considered unmarried on the last day of the year, which means you must: File your taxes separately from your spouse. Pay more than half of the household expenses. Not have lived with your spouse for the last 6 months of the year.
