How Can I Get My Audit Number Online?

An audit number serves as a specific identifier found on official communications from tax authorities. This number is used to uniquely tag your case or inquiry within their system. It acts as a reference point, ensuring your communications are accurately matched to your particular situation.

Finding Your Audit Number on Notices

Official notices from tax authorities, such as the Internal Revenue Service (IRS) or state tax departments, typically include a unique identifying number. This number is often labeled as a “Notice Number,” “Control Number,” “Audit ID,” “Reference Number,” or a similar “Letter ID.” For IRS notices, this number is usually located prominently on the first page.

You should look for this identifier in the top right-hand corner, top left-hand corner, or within a distinct box on the document. A control number is often found on IRS letters and is their internal tracking number for your specific case. This number is distinct from personal identifiers like your Social Security Number (SSN) or Employer Identification Number (EIN). Always ensure you are looking for the specific notice or control number, as opposed to other identifying information on the document.

Retrieving Your Audit Number Through Online Accounts

If you do not have the physical notice, you may be able to retrieve your audit number through the relevant tax authority’s online portal. To begin, you will likely need to create or access an existing online account with the Internal Revenue Service (IRS) or your state’s tax agency. For the IRS, this involves navigating to IRS.gov/account.

Setting up an online account typically requires a robust identity verification process. This often involves providing personal information like your Social Security Number or Individual Tax Identification Number, and uploading a photo of a government-issued identification document.

Once your identity is verified and your account is established, you can sign in to access various tax-related information. Within your online account, you should look for sections such as “Tax Records,” “Correspondence,” or “Notices.” The IRS online account allows you to view digital copies of select notices and your audit status. While not all correspondence may appear in your online account, many common notices are typically accessible.

What Your Audit Number Means

The audit number is a unique identifier assigned to a specific communication or inquiry initiated by a tax agency. Its primary function is to link the notice directly to your individual or business tax account. This number helps the auditing agency track and manage your case.

This identification number is essential when corresponding with the tax authority, whether you are providing requested documentation, asking questions, or disputing information. Having the audit number readily available allows the agency to quickly locate your file and understand the context of your communication. It serves as a case number, streamlining interactions and facilitating efficient resolution of the inquiry.
