A full package of tax return software, T1, T2, T3, etc... for Canadian tax. The T2 and T3 are good but similar to Tax Prep and Profile (just a better interface), however the real benefit is with the T1 as it come useful letters for pre-tax season, decreased engagement letter, engagement letter, client letter, etc... It is less expensive then competing software but generally a better interface and customer service. So I think this is the best of the desktop tax software in Canada. If you used Profile, it is very similar with the same F4, F5 keys on the software and a similar but better interface.
