Do you have to mail each individual income tax form separately or can you combine multiple years?

Question

I am mailing my amended 03 and 04 kansas tax forms. Can I combine them in one envelope, or do I have to mail each separately?

Answer 1

You may put both forms in one envelope. Just make sure that all the forms for one year are stapled together.

Answer 2

You could combine them.  There is no rule that you can't.  Unfortunately, the state will probably s***w them up if you mail them together.

I always tell clients to mail each year on its own.  Better to be safe than sorry.

Answer 3

Mail each year separately.  Otherwise it's very possible they'll get stapled together on the other end, and it could delay processing.
