Does USPS mail forwarding notify the IRS?

No. USPS forwarding redirects your mail for a while, but it isn’t a reliable way to update the address the IRS has on file. And the IRS warns that post offices don’t always forward government checks, so a paper refund can still go missing. Tell the IRS directly with Form 8822.

What does USPS forwarding do — and not do?

Does: redirect most first-class mail to your new address, typically for 12 months.
Doesn’t: reliably update the IRS — USPS may relay your move through its NCOA database, but not dependably. (Social Security and your state aren’t updated at all; each keeps its own address file.)
Doesn’t: reliably move government checks. The IRS warns that post offices don’t always forward government checks — which is exactly how a paper refund goes missing during a move.

The IRS’s own guidance (address-changes FAQ) is to notify it directly when you move. The dedicated way for individuals is Form 8822, mailed to the IRS office for your old state — there’s no online option.

The right move sequence

Set up USPS forwarding (catches everything for a year).
Mail Form 8822 to the IRS (fixes the record that matters for refunds, notices, and deadlines).
After 4–6 weeks, verify in your IRS Online Account.

Common questions

Does USPS mail forwarding notify the IRS?

No — not reliably. USPS change-of-address forwards your mail and may pass your new address to the IRS through its NCOA database, but it’s not dependable. The IRS says to notify it directly — Form 8822 by mail is the dedicated way.

Will my IRS refund check be forwarded to my new address?

Often not. The IRS warns that post offices don’t always forward government checks, and it tells taxpayers to notify it directly to avoid refund delays.

Is USPS forwarding still worth doing?

Yes — do both. Forwarding catches everything else during the move window (typically 12 months for first-class mail); Form 8822 fixes the IRS record permanently.
