I just remember looking that up some years ago and wondered if they have something available for Canadian tax.  Didn't know they have a Canadian version of TurboTax but wouldn't be surprised.

In fact, it turns out Intuit also had a UK professional tax product many years ago.  That product called TaxCalc was bought over by another company which continues to develop it through the years for use by accounting firms, business owners, and individuals.  Stumbled upon it while looking for tax software to prepare my first UK returns.
