Learn About IRS IP PIN Protection and Identity Theft Prevention

What Is an IRS IP PIN and Why It Matters

An IP PIN stands for "Identity Protection Personal Identification Number." It is a six-digit code that the Internal Revenue Service (IRS) issues to taxpayers as a security tool. When you have an IP PIN, only you and the IRS know this number. If someone tries to file a tax return using your Social Security number without knowing your IP PIN, the IRS's computer system will reject that return.

The IRS created the IP PIN program in response to a serious problem: identity theft using tax returns. According to IRS data, tax-related identity theft remains one of the most common forms of identity fraud. Criminals steal personal information and file false tax returns in someone else's name to claim refunds. In some cases, these fraudulent returns are filed before the actual taxpayer files their legitimate return, creating confusion and delays.

Think of an IP PIN like a password for your taxes. The IRS has approximately 4 million taxpayers enrolled in its IP PIN program as of recent years. Some of these people enrolled because they were victims of identity theft. Others requested an IP PIN voluntarily as a preventive measure. The program offers an additional layer of protection beyond the standard security measures the IRS uses.

Without an IP PIN, a thief who obtains your Social Security number and basic personal information could potentially file a return in your name. With an IP PIN, they cannot complete the filing without this six-digit code. This makes tax fraud using your identity significantly more difficult.

Practical takeaway: Understanding what an IP PIN is helps you recognize whether this tool might reduce your risk of tax-related identity theft. The PIN is one of several options available to taxpayers concerned about identity protection.

How the IRS IP PIN Program Works

The process of obtaining and using an IP PIN involves several steps. First, you must request one from the IRS through specific channels. The IRS does not automatically issue IP PINs to all taxpayers. Instead, you must take action to request one. The primary methods for requesting an IP PIN are through the IRS website or by mail.

When you receive an IP PIN, the IRS sends it to you in writing, typically by mail to your address on file. This is an important security feature—the PIN arrives through postal mail rather than email, making it harder for criminals to intercept electronically. You must then use this PIN when filing your tax return. The PIN goes on specific lines of your return form.

Here is how filing works once you have an IP PIN. When you submit your return—whether by paper or electronically—you must enter your PIN in the designated spot. If you file electronically, your tax software will have a field where you enter this information. If you file by paper, you write it on the form itself. The IRS computer system verifies that the PIN matches the one on file for your Social Security number. If someone tries to file a return with your Social Security number but provides the wrong PIN or no PIN at all, the return is rejected.

The IRS typically issues IP PINs for one year at a time. This means you receive a new PIN each year, usually in December or early January before the tax filing season begins. If you have an IP PIN, you need the current year's PIN to file that year's return. Using an old PIN from a previous year will not work.

The program has some limitations. An IP PIN only protects you against someone filing a return using your Social Security number. It does not protect you against other forms of identity theft, such as fraudulent credit card applications or utility account creation. However, for tax-specific identity theft, it is an effective tool.

Practical takeaway: Knowing the step-by-step process of how IP PINs function helps you understand what to expect if you decide to use this protection method. The system works by requiring something only you should know—your personal PIN.

Who Should Consider an IP PIN

Not every taxpayer needs an IP PIN, but certain groups face higher risk of tax-related identity theft and may find this tool particularly useful. Understanding whether you fall into a higher-risk category can help you make an informed decision about whether to pursue an IP PIN.

People who have already been victims of identity theft are prime candidates for an IP PIN. If someone has already filed a fraudulent return using your Social Security number, the IRS can issue you an IP PIN to prevent it from happening again. According to IRS statistics, victims of tax-related identity theft often remain at higher risk for future incidents, sometimes for several years after the initial theft.

Certain professions and situations increase your risk. For example, if you work in government or have access to sensitive databases, you might be at higher risk because criminals specifically target people with access to personal information. If you have experienced a data breach—such as when a company you do business with has information stolen—you may want to consider an IP PIN. People who suspect they may have been victims of identity theft but have not yet filed a tax return that year should consider requesting an IP PIN before filing.

Elderly people and children are also higher-risk groups. Criminals sometimes use the Social Security numbers of elderly individuals or children because these identity thefts may go undetected longer. A child, for example, may not file a tax return for many years, creating an opportunity window for a criminal to file false returns and claim refunds. Some parents request IP PINs for their children as a preventive measure.

You might also consider an IP PIN if you have experienced other forms of identity theft or suspicious account activity. People who regularly monitor credit reports and notice fraudulent accounts or inquiries sometimes decide to add IP PIN protection as an extra safeguard, even if tax theft has not yet occurred.

However, some taxpayers who file through a tax professional or preparer may find that an IP PIN creates complications. If your tax preparer does not know your PIN or enters it incorrectly, your return will be rejected. This is why communication with your preparer about whether you have an IP PIN is important.

Practical takeaway: Evaluate your personal risk factors. Those with previous identity theft incidents, access to sensitive information, or concerns about data breaches may benefit most from understanding how an IP PIN works and how to obtain one.

Steps to Request an IRS IP PIN

The IRS provides several methods for requesting an IP PIN, and the method you choose may depend on your situation and preferences. One of the most convenient options is through the IRS website at irs.gov. The IRS maintains a specific online portal where you can request an IP PIN if you have never been the victim of tax-related identity theft but want to protect yourself preventively.

To use the online method, you will need to create or access an IRS account on the official IRS website. You must provide your Social Security number, date of birth, and other personal information to verify your identity. The IRS uses this information to confirm that you are the actual owner of the Social Security number. Once your identity is verified, you can request an IP PIN through the portal. In many cases, the IRS generates and displays your PIN immediately on the screen, or sends it to you by mail within a specific timeframe.

If you are a victim of tax-related identity theft, the process differs slightly. You must file IRS Form 14039, which is the "Identity Theft Affidavit," along with your tax return. This form notifies the IRS that you have been a victim of identity theft. When you file this form, the IRS will issue you an IP PIN. You may also contact the IRS by phone to report identity theft, though wait times can be lengthy.

You can also request an IP PIN by mail. You fill out the appropriate form and send it to the IRS at the address specified in their instructions. This method takes longer—typically several weeks—but it is an option if you prefer not to use online systems or if you cannot access them.

Important details to remember: have your Social Security number, date of birth, and any relevant documents available before you begin. If you have already filed a return that year, you cannot get an IP PIN through the preventive online system. If you have already filed and then become aware of identity theft, you must use the identity theft affidavit process instead.

Keep your IP PIN safe once you receive it. Treat it like you would treat your Social Security number. Do not share it with anyone except your tax preparer if you use one. Write it down and store it somewhere secure, or remember it if possible. You will need it every year when you file your
