W7 Mailing Address: Where to Send Your Form W-7 and Documents

Filing a Form W-7 is an essential step for individuals who need to obtain or renew an Individual Taxpayer Identification Number (ITIN) in the United States. This process involves submitting specific documentation along with the form, which requires careful attention to ensure timely processing by the IRS.

Standard Mailing Address

Using the correct mailing address is crucial for efficient processing of your Form W-7. As of 2024, mail your completed form and accompanying documents to: Internal Revenue Service, ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342. This address directs your application to the appropriate department. Incorrectly addressed mail can result in delays or returns, so double-check the address before submitting.

Private Delivery Service Address

For private delivery services like FedEx, UPS, or DHL, use a physical address, as these services do not deliver to P.O. Boxes. The correct address for 2024 is: Internal Revenue Service, ITIN Operation, 3651 S. Interregional Hwy 35, Mail Stop 6091 AUSC, Austin, TX 78741-0000. Private delivery services often provide tracking and faster delivery, which can be helpful during peak processing times. Retain tracking information as proof of submission.

Documentation to Include

Form W-7 requires original documents or certified copies from the issuing agency to verify identity and foreign status. Acceptable identification includes a passport or a combination of documents such as a national ID card, U.S. driver’s license, or foreign voter registration card. These must include an expiration date, photograph, and relevant identifying details. Attach a federal tax return unless you qualify for an exception, in which case additional supporting documentation is required. Exceptions, such as for students or researchers claiming tax treaty benefits, are detailed in IRS Publication 1915.

Processing Timeline

The IRS generally processes Form W-7 applications within seven weeks, though timelines may be longer during peak tax season (January through April). Ensure all forms and documents are complete and accurate to avoid delays. Incomplete applications or missing information may result in requests for additional documentation, further extending the timeline. International applicants may face longer processing times due to mailing and verification of foreign documents.

Confirming Delivery

After submitting your Form W-7, confirm delivery to ensure the IRS has received your application. Private delivery services provide tracking and delivery confirmation. For standard mail, use USPS certified mail with a return receipt for proof of delivery. Retain proof of submission as evidence in case of processing delays or disputes. The IRS does not send immediate acknowledgment of receipt; the first indication is typically the issuance of the ITIN or a request for additional information.
