I am sending my state return through regula mail and the instructions says:
"attach the orginals or copies of the original state wage and tax statements"
Does this mean the w-2 or any other income documents?
For more it is the W-2's however if you have other documents that have Federal and/or State taxes withheld they need to be sent in also.
This might include a 1099R, and SSA-1099 (these would only be included if taxes were withheld).
