Can I install TT Business on the same computer that has TT Premier installed and use both independently?
Yes you can install the TurboTax Business Edition and any of the TurboTax personal editions (Basic, Deluxe, Premier or Home and Business) on the same computer for the same tax year. The Business and Personal software do not interact with each other. The Business Edition tax data file and the Personal editions tax data files are separate and one cannot be used with the other.
