What Is a Tax PIN Number and How Do I Get One?

A tax PIN number, in the context of individual taxpayers, generally refers to a unique six-digit Identity Protection Personal Identification Number (IP PIN) issued by the Internal Revenue Service (IRS). This PIN serves as a security measure, functioning as a unique identifier during tax filings to confirm the taxpayer’s identity. Its primary purpose is to help prevent tax-related identity theft by adding an extra layer of protection to an individual’s tax account. The IP PIN ensures that only the legitimate taxpayer can file a return using their Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN).

Identity Protection PIN Explained

The Identity Protection PIN (IP PIN) is a six-digit number that acts as a secret key, known only to the taxpayer and the IRS, designed to prevent tax-related identity theft. It serves as a pre-emptive defense mechanism, ensuring that if a fraudulent return is attempted using a stolen Social Security number or Individual Taxpayer Identification Number, it will be rejected without the correct IP PIN.

The IRS issues IP PINs to victims of tax-related identity theft who have had their cases resolved, providing them with ongoing protection. Any taxpayer who can verify their identity can also opt-in to receive an IP PIN annually for enhanced security. This voluntary program allows individuals to proactively secure their tax accounts, even if they have not previously experienced identity theft.

The IP PIN prevents the processing of a tax return that lacks this unique identifier, even if all other personal information matches. When an IP PIN is issued, it becomes mandatory for filing any federal tax return associated with that SSN or ITIN for the given tax year.

How to Get an Identity Protection PIN

Taxpayers primarily use the online “Get an IP PIN” tool on the IRS website. This digital service is the quickest method for most individuals to receive their unique six-digit number. To use the tool, taxpayers must first authenticate their identity through the IRS Secure Access authentication process, which requires knowledge-based verification of financial account information or credit product data.

After successfully completing the identity verification steps, the IP PIN is immediately displayed on the screen. Taxpayers should print or securely save this number, as it will be required for filing their federal tax return for the current year. A new IP PIN is issued each year, so individuals must repeat this process annually to obtain their updated number.

For taxpayers unable to use the online tool, alternative methods exist. One option is to complete and mail Form 15227, Application for an Identity Protection Personal Identification Number. This form can be submitted to the IRS, and after identity verification, the IP PIN will be mailed to the taxpayer’s address of record.

In situations where neither the online tool nor Form 15227 is viable, taxpayers may verify their identity in person at a designated Taxpayer Assistance Center (TAC). An appointment is required for TAC visits, and taxpayers should bring specific identification documents. Once identity is confirmed, the IP PIN can be issued.

When to Use Your Identity Protection PIN

Once obtained, the Identity Protection PIN (IP PIN) becomes a mandatory component for filing your federal tax return for the tax year it was issued. This six-digit number must be accurately entered on both electronically filed and paper tax returns to ensure proper processing. Without the correct IP PIN, your tax return will be rejected by the IRS.

For taxpayers filing electronically, the tax software will prompt for the IP PIN during the filing process, typically in a specific field within the personal information section. When preparing a paper return, the IP PIN should be written clearly in the designated box on Form 1040, U.S. Individual Income Tax Return, or the appropriate corresponding tax form.

The IP PIN is required for the primary taxpayer listed on the return. If filing a joint return, both the primary taxpayer and the spouse must enter their respective IP PINs if each has been issued one. If a dependent on the tax return has been issued their own IP PIN, that number must also be included in the appropriate section of the return.

What to Do If You Lose or Forget Your IP PIN

If you have misplaced or forgotten your Identity Protection PIN (IP PIN), the most efficient way to retrieve it is by utilizing the online “Get an IP PIN” tool on the IRS website. This secure tool allows immediate access to your current year’s IP PIN after successfully verifying your identity. The identity verification process requires answers to personal financial questions to confirm your identity.

If you do not receive your annual IP PIN in the mail by mid-January, or if you suspect your IP PIN has been compromised, use the “Get an IP PIN” online tool. If the online tool does not resolve the issue, or if you believe your identity has been further compromised, contact the IRS directly for assistance.
