If you have already
filed your tax return and it has been rejected by the IRS...you can edit the address
and fix the reason for rejection and re-efile your return, but If your return is
accepted by the IRS, or you if sent your tax returns through the Post Office then there is no way to change the address.
Make sure that you
have your mail forwarded to your new address by filling out the proper forms
from the Post Office. If you have not filled these out yet, I would do so as
quick as possible.
