No, you cannot use both Home and Business and Premier on the same computer. There is no need for that at all. Any version of desktop software can be used to prepare and e-file up to five federal returns and the state returns that go with them. You do not need --- and cannot install successfully--- two versions of the same year of desktop software on the same computer. Anything you could do on Home and Business can be done using Premier. You just get a little more help in the interview screens with Home and Business. Premier has all the same forms and schedules. If you really want Home and Business then you can just upgrade the Premier software you already have up to Home and Business. Trying to put in another download is just a waste of money and effort.
