I had a relatively complicated return this year with part-year residences in two states, investment and pension income, and self-employment income. TurboTax was a delight to use as it walked me through all of the applicable issues. Since I have used TurboTax in the past, all of the necessary information was transferred automatically. Things could not have been easier.
What's great about it: Easily dealt with part-year residency in two states
