I have used H&R Block Tax software for 15 years and always found it intuitive and accurate to the best of my knowledge. Usually give it a 5-star, but this year there was some kink in the software that the support line could not resolve and basically just left me hanging. I did a tacky work around, putting in a number I knew was not correct just to satisfy the software since I knew that particular form (Schedule A) would not end up in my final submission. But not cool!
WHEN YOU ARE ALL FINISHED, I do everything that is asked and complete it finds errors that are extremely difficult to fix. I write the same review every year and it is still the same.
