📌 IRS Mailing Tips for 2026

📬 Certified Mail

Always use certified mail with return receipt requested. This provides proof of delivery and establishes the date of filing. Without it, you have no proof the IRS received your documents.

📝 Address Verification

Always verify the address in the current year's form instructions. Addresses can change. This tool is updated for 2026, but double-check with the official IRS website.

⏰ Filing Deadlines

For time-sensitive documents, mail well before the deadline. Consider using overnight mail for last-minute filings. Private delivery services (FedEx, UPS) have different addresses – check the instructions.

📎 What to Include

Your name, address, and SSN on all pages
Signed and dated forms
Copies (not originals) of supporting documents
Check or money order if paying (payable to "United States Treasury")
Form 843? Include detailed explanation
Form 8857? Include sworn declaration

📋 Common Address Mistakes

Using old addresses from previous years
Using the wrong processing center for your state
Not including "Internal Revenue Service" in the address
Using private delivery service addresses for certified mail
Forgetting to use certified mail

📬 Private Delivery Services

FedEx, UPS, and DHL have specific addresses that are different from USPS addresses. Check the form instructions for the correct private delivery address. This tool provides USPS addresses for certified mail.

📋 Why Address Matters

Using the wrong address can cause significant delays in processing your forms, missed deadlines, and even lost documents. The IRS has different addresses for different forms and locations.

❓ IRS Address Finder FAQ

Where do I mail Form 1040-X (Amended Return)?

Ogden, UT: Alaska, Arizona, California, Colorado, Hawaii, Idaho, Illinois, Iowa, Kansas, Minnesota, Missouri, Montana, Nebraska, Nevada, North Dakota, Oregon, South Dakota, Utah, Washington, Wisconsin, Wyoming
Covington, KY: All other states and territories.

Where do I mail Form 843 (Penalty Abatement)?

Form 843 is mailed to:

Internal Revenue Service
1973 N. Rulon White Blvd.
Ogden, UT 84201

This address is used regardless of your location.

Where do I mail Form 8857 (Innocent Spouse Relief)?

Form 8857 is mailed to:

Internal Revenue Service
Stop 6716 AUSC
1973 N. Rulon White Blvd.
Ogden, UT 84201

Note the "Stop 6716 AUSC" line – this is important for proper routing.

Should I use certified mail?

Yes, absolutely. Certified mail with return receipt requested provides proof that the IRS received your documents. This is crucial for statute of limitations, especially for Form 843 (2-year deadline) and Form 8857 (2-year deadline). Without proof, you have no evidence of timely filing.

What's the difference between USPS and private delivery service addresses?

The IRS has different addresses for USPS and private delivery services (FedEx, UPS, DHL). This tool provides USPS addresses for certified mail. If using FedEx or UPS, check the form instructions for the specific private delivery address – they are often street addresses rather than PO Boxes.

How often do IRS addresses change?

IRS addresses occasionally change. This tool is updated for 2026, but always verify in the current year's form instructions before mailing. The instructions are available at IRS.gov.

What if I live outside the United States?

If you live outside the US, use the Ogden, UT address for most forms. For specific forms like 1040-X, check the instructions. International filers should also consider using certified mail through the USPS or international tracking services.

Can I e-file instead of mailing?

Many forms (like 1040-X for 2021-2025) can now be e-filed. Check if your form is eligible for e-filing. This is faster and provides immediate confirmation. However, some forms (like 843 and 8857) still require mailing in most cases.

What should I include with my mailed form?

Include: (1) your name and SSN on every page, (2) signed and dated forms, (3) copies (not originals) of supporting documents, (4) a check or money order if paying (payable to "United States Treasury"), and (5) a cover letter explaining what you're sending. Use certified mail with return receipt.

How accurate is this address finder?

This tool is updated for 2026 based on current IRS form instructions. However, addresses can change. Always verify with the official IRS form instructions before mailing. This tool is a guide, not a substitute for official verification.
