successful letters for app fee waivers?

i am going to contact my various schools regarding application fee waivers, but before i do, what has worked for people? tax returns? hard numbers? or just descriptions of circumstances? thanks!

So I got app fee waivers for 10 of my 15 apps. Most of the time schools either wanted financial aid data or a copy of a GRE fee reduction certificate. Some schools said that tax returns would be acceptable for applicants that have been out of school for a while.
