Makes taxes easy! Several years ago I noticed this software missed a state tax credit for the care of a child with a developmental disability. I let them know, and the next year it was fixed. I've used this software every since.
Pros: Easy to install, Easy to prepare, Maximizes refund, Easy to import, Fast
I've been using H&R Block tax software for a number of years (after their competition became unreasonable) and have never regretted the change. I have never caught an error.
