You have to use your correct mailing address in MY INFO so that the IRS and your state will have the address to use if they need to mail you a letter or a check. Did you already e-file? If not, go back to MY INFO and make sure the right address is there. If you already e-filed with the old address, you need to send a change of address to the IRS now.
