Besides being fairly easy, the best thing is it knows what to do with deductions, interest and dividends and stock gains and losses. I would have no idea what qualifies and where to put it.
I've been using this software for years now and even though I'm retired with multiple income streams (Social Security, Pension, Stocks & Bonds, 401K), it easily handles it all.
My taxes are very simple and H & R Block Deluxe tax preparation software easily completes the calculations for my return and e-files. It is less expensive than the popular Turbo Tax, but I find it less intuitive as a user.
