It was fairly easy to search out IRS forms but then you find out they're not usable because they're in Red!?! Also it said if you paid for a one-year subscription you save 65%, but the yearly cost was exactly the same as paying monthly and you didn't know this until you processed your payment???
Judi
Worth the money! The software is very easy to use from a smartphone or computer. Most people don't own a fax machine, so this feature is very handy! The subscription is necessary, but now with many places of business using editable PDFs, it's not needed as often as I'd like.
