Key takeaways

- Form 8822 is commonly used for individual IRS mailing address changes.
- Businesses and responsible parties generally use Form 8822-B.
- IRS processing can take several weeks, so file early.
What USPS Change-of-Address does
USPS COA forwards many pieces of mail from your old address to your new one for a limited window. It is useful after a move, but it is not a replacement for direct agency record updates.
What IRS Form 8822 does
Form 8822 updates your IRS mailing address on file for individual-related tax correspondence.
Use it when:
- You moved and want future IRS notices sent to your new address.
- You need to correct the IRS mailing address currently on file.
When to use Form 8822-B instead
If the address change relates to a business or responsible party update, Form 8822-B is usually the relevant form.
Practical filing workflow
- Confirm whether your situation is Form 8822 or Form 8822-B.
- Complete the correct form with old and new address details.
- Verify signatures and required identifying details.
- Mail to the correct IRS destination in current instructions.
- Keep mailing proof and note when IRS processing should be complete.
Timing and deadline planning
IRS indicates address updates can take roughly 4 to 6 weeks. If you are near a response deadline, do not wait until the last few days.

- Assuming USPS COA automatically updates IRS records.
- Filing the wrong form (8822 vs 8822-B).
