In theory one is supposed to check their returns before signing them - even if someone else does them for you. However, I seriously doubt that even 25% of people do that. They just want a refund or to get it over with.
I don't buy homo saps saying they didn't know what the tax accountant did. I mean what degree of stupid dumb would it take to do that? Sign something you didn't read and understand COMPLETELY?
I guess folks sign things all the time that they don't read...at least the fine print. Go figger! Thank you for your reply Shuhak! :)
