For a T1 with both T4 and T5 slips, TurboTax Premier is the best option.

The cost is $50 per return (online DIY). While the free version is adequate for basic T4S, Premier is required for investment income (T5). It provides specialized guidance for interest and dividends, as well as improved tools for importing data from financial institutions to ensure accuracy.
