Get your taxes done using TurboTax

It should work.  I used Bootcamp to run a Windows installation of Quickbooks a few years ago.  As mentioned by others, Bootcamp is free but you will need to have a valid copy of Windows from somewhere to install on the Bootcamp partition.  There are commercial software solutions that include a copy of Windows, but I don't have current knowledge of the various prices involved.  You might also find it simpler to buy a cheap used PC.
