Does Social Security notify the IRS of an address change?
No. The Social Security Administration and the IRS keep separate address files, each for its own mail. Changing your address with the SSA keeps your benefits and your year-end SSA-1099 on track — but it does nothing for your IRS record. For tax notices and refunds, tell the IRS directly with Form 8822.
Why don’t the SSA and IRS sync?
They’re different agencies with different jobs and different mailing lists. Your SSA address controls benefit letters and the SSA-1099; your IRS address controls tax notices, balance-due letters, and paper refund checks. Updating one simply doesn’t reach into the other’s system — the same reason USPS forwarding isn’t a reliable way to update the IRS either.
Who do you need to tell when you move?
| Who | How | Why it matters |
|---|---|---|
| IRS | Form 8822 (mail only) | Tax notices, deadlines, paper refund checks |
| Social Security | my Social Security online, or call SSA | Benefit letters, SSA-1099 |
| USPS | Change of address | Forwards most mail for ~12 months |
| Your state | Your state tax agency | State refunds and notices — separate from the IRS |

Common questions
Does changing my address with Social Security update the IRS?
No — the SSA and the IRS keep separate address records, each for its own mail. Updating one doesn’t update the other, so notify each directly.
Do I have to tell the IRS and Social Security separately when I move?
Yes. Tell the SSA so your benefits and SSA-1099 reach you, and tell the IRS (Form 8822) so tax notices and refunds do. Neither updates the other.
What’s the IRS way to change my address?
For individuals there’s no online form to submit — Form 8822, signed and mailed to the IRS center for your old state.
