Has anyone had problem with the Post Office returning mailed envelopes (for 06-15 Estimates) to the IRS PO BOX number? The address is correct per the Voucher form. "Return to Sender, Not Deliverable as Addressed, unable to forward" .
Photograph the envelope and then I would put that envelope, unopened, into another envelope and send it to your local service center with a letter that says "HUH?" I actually had a rubber stamp made that said HUH? for the regular IRS letters that were posted the same day - one said you owe XXX and the other said your refund has been increased to YYY. I am bouyed by the fact that things have not really changed, even though they are different.
I know this problem was also posted by at least one other user.
