I prepared the return filing joint. Is there an easy way to see what the ta difference is if we file married filing separate without reentering all the information

Is there an easy way to find out the tax liability if we filed separate but married versus filing joint or do I need to reenter all data

You can do it but it is not easy. You would have to create new user names for each of you and fill out fake returns with only one individual's information on each. Afterwards, you can abandon the returns. Keep in mind that if one of you itemizes, the other loses the standard deduction and would have to itemize as well. Also you can;t double dip on the mortgage and property taxes. You could pro-rate them however you wish up to 100%.
