I had problems with the IRS accepting my return because of an update that had not been available at the time I filed. I finally got the update on Feb 15th, refiled and my return was accepted.
This year, our federal tax return included a few rarely used forms, and also some new sources of income. I still completed the return with amazing ease, and our refund is set to be direct deposited just 8 days later. Can't recommend this product highly enough!
Pros: Easy to prepare, Easy to import documents, Fast
