<prompt> Human: I just got a letter from the IRS that has my address, but somebody elses name on it. Ive been at my address for about a year and a half, and I know its not the previous tenant. What can I do to make sure that 1 the IRS knows that this person doesnt live here or 2 the person who was supposed to get the letter gets it?I know this isnt really a personal finance question, but since it involves taxes and such, I figure this might be the best place to find somebody who knows what to do in my situation.  <response>: Write Return to Sender. Not at this Address on it and put it back in the mailbox. The post office will return it to the IRS and theyll know that person isnt at that address.Note, the post office will also stop delivering all mail with that name to your address, so dont do this if you just want to dodge one letter
