I'm assuming you mailed a paper return. If you e-filed, the IRS may still reject your return and then you can just go back into your return and correct your information.
Did you select direct deposit as your refund method? If so, the
deposit will still go through just fine. I would recommend submitting IRS Form 8822, which is the change of address form to ensure that they have the correct address on file. Here's a link to the form https://www.irs.gov/uac/Form-8822,-Change-of-Address.
If
you requested a paper check mailed to you, please contact the IRS to
ensure that they have the correct address to mail the check. Please
call 800-829-1040, Monday - Friday, 7:00 am - 7:00 pm local time.
There are similar procedures in place for your state department
of revenue, if applicable. Simply follow the basic process above (find
out if there is a dedicated form to file, or you can call them and
verbally tell them your new address).
