Have been using this product for the at least the last ten years without issue. The ability to import data from the previous year and process files from other sources make tax preparation very efficient and easy, as I can do my federal and state taxes in a minimal amount of time.
Pros: Easy to prepare, Easy to import documents, Fast
Block sometimes asks for information that is contained in last year’s return. The program gathers some information from last year but makes you search for other information. When errors are found it isn’t always clear what should be done to correct the error.
