I suggest you only send copies of the tax returns and W-2s or tax transcripts with the I-864. Don't send original documents.
Also, the Authorization for release of tax data is no longer needed.
I agree with Mononoke, send photocopies only (Tax return, W-2s, etc). I am keeping the originals and giving it to my wife come interview time if they need to verify it.
Also, if you are only going to petition your spouse AND will only need income to show proof, use the I-864EZ form. It's SO much simpler to fill out.
As for the tax release form, I'll let you know next week. I am expecting the mailed I-864 instruction packet by then (crosses finger). I was going to use James' shortcut but since I am also waiting for the IV Bill, I won't really save any more time if I send it ahead.
Good Luck!
