Answer:   Yes, if you move, you need to notify the IRS of your new address. We can change our records so that any tax refunds due to you or any other IRS communications will reach you in a timely manner.  If you filed a joint return, you should provide the same information and signatures for both spouses. If you filed a joint return and you and/or your spouse have since established separate residences, you both should notify the IRS of your new addresses.

There are several ways to notify the IRS of an address change:

• Tax Return: Update your address in the appropriate boxes on your tax return;
• Form 8822: Submit Form 8822, Change of Address, to request an address change;
• Written Notification: Mail a signed written statement to an appropriate Service address informing the Service that you wish that the address of record changed to a new address.  Generally, the appropriate Service address is the campus where you filed your last return.  In addition to the new address, this notification must contain the taxpayer’s full name and old address as well as the taxpayer’s social security number, individual taxpayer identification number, or employer identification number;
• Oral Notification: Provide an oral statement in person or directly via telephone to a Service employee who has access to the Service Master File informing the Service employee of the address change. In addition to the new address, you must provide the taxpayer's full name and old address as well as the taxpayer’s social security number, individual taxpayer identification number, or employee identification number;
• Electronic Notification: Submit new address information through one of the secure applications found on the IRS website, such as Where’s My Refund?.  In addition to the new address, you must also provide the taxpayer’s social security number, individual taxpayer identification number, or employer identification number, as well as any additional information requested by the specific application.  You cannot notify the IRS of an address change through other forms of electronic notification, such as electronic mail sent to an IRS email address.

Note: The IRS automatically updates your address of record based on any new address you provide to the U.S. Postal Service (USPS) and the USPS retains in its National Change of Address database.  However, even if you notify USPS with your new address, it’s still a good idea to notify the IRS directly.

Caution:  If you are a representative signing on behalf of the taxpayer, you must attach to the written statement or Form 8822 a copy of your power of attorney.  To do this, you can use Form 2848.  The Internal Revenue Service will not complete an address change from an "unauthorized" third party.
