I can tell this much. My personal return was extended and had to be mailed in. I mailed the check for the balance due with the return. In less than 10 days, the check was deposited and cashed by the IRS. Still no confirmation on the processing of the return. I sent it certified mail, got the greed card, they got my money. I guess it is they'll take the money and run and wait forever and a day to process the return. I thought for sure that mailing would have floated around somewhere in Charlotte for at least three or four months. However, it is proven this was not the case.
