The General Instructions for Certain Information Returns say: "Form 1096 must accompany all paper submissions."
But, the instructions for Form 1096 say: "Caution: We recommend you file Form 1099-MISC, as a stand-alone shipment, by January 31, 2019, if you are reporting nonemployee compensation (NEC) in box 7" (which I am).
So, which is it? Do I mail Form 1096 in the same envelope as Form 1099-MISC, or do I mail each form separately, in its own envelope?
If I'm supposed to mail them together in the same envelope, where do I mail that envelope? Given that my principal business office is located in Connecticut, the General Instructions for Certain Information Returns say to "send all information returns filed on paper" to Ogden, UT, but the instructions for Form 1096 say to "send all information returns filed on paper with Form 1096" to Austin, TX.
