How to change your address for Missouri state taxes
To change the address on your Missouri taxes, go through the Missouri Department of Revenue — the options are below. Do it separately from the IRS, though: updating your Missouri address does not change your federal record, so you’ll also need to file Form 8822 with the IRS.
