Very comprehensive and easy to use. I had only one difficulty and that was trying to enter my royalty information from my 1099-MISC. The accuracy check at the end kept refusing to accept what I had entered. It was not very helpful in showing me what was wrong but I finally figured it out and filed the return successfully.
Easy to use especially after year one. The first you you have to load everything into the data base. The following years it knows all the banks, forms, partnerships etc. so it prompts you to just fill in the blanks from the ones you had in past years. You only need to fully fill out for new ones.
