A stolen Social Security number can turn into a filed tax return before you ever open your tax software. The IRS offers one tool aimed at that problem, the Identity Protection PIN, or IP PIN. The IRS pages we reviewed confirm the purpose of the PIN and the agency's push to get more people to use it. They do not show us the sign-up steps, so this guide marks what is confirmed and what you should check on IRS.gov before you act.
What an Identity Protection PIN Is
An IP PIN is a number the IRS issues to taxpayers as a way to guard against tax-related identity theft [5]. The idea is simple. The IRS wants a second piece of proof tied to your return, beyond a name and a Social Security number. A thief who has your number but not your PIN has a harder job.
The IRS also links its Online Account and identity protection PINs in one announcement about protection against fraudsters [7]. That headline suggests the Online Account is one place the IRS expects people to deal with the PIN. We only saw the headline, so read the full page for how the two connect.
- The IRS presents the PIN as protection against tax-related identity theft.
- The IRS ties the PIN to its Online Account in its messaging.
Why the IRS Wants More People to Sign Up
The IRS has encouraged all taxpayers to sign up for an IP PIN for the 2025 tax season [8]. Notice the word all. The pitch is not aimed only at people who already had a problem. It is aimed at anyone with a Social Security number and a filing obligation.
A separate IRS reminder urges taxpayers to take steps now to protect their tax information [6]. The timing message is clear from the headline. Act before you file. Do not wait for a rejected return to tell you something is wrong.
One caution. The 2025 guidance was written for that tax season. We could not confirm whether it carries over unchanged to later years, so look for the IRS notice for the season you are filing in.
What We Could Not Confirm
The pages we received were mostly headers, menus and boilerplate. The text that explains the process was missing. That matters, because the practical details are the part most readers want. Rather than guess at them, we list them here as open questions to settle with the IRS.
- How to get a PIN, including online, mail or in-person options, and the identity checks involved [1].
- Who is eligible, and whether a new PIN is needed each year [2].
- Any cost, and the PIN format.
- What happens if a return is filed without the PIN.
- How to recover a PIN that was lost or never arrived [4].
Each item is a detail people commonly need. A wrong guess on any of them could send you down the wrong path, or toward a look-alike site. Scam pages copy IRS wording, so type irs.gov yourself or use the links in this article, and be wary of anyone who offers to get a PIN for you.
Where to Go Next
Start with the IRS page titled Get an identity protection PIN [1]. Then read the IRS frequently asked questions on the IP PIN [2]. Those two pages are where the IRS places its instructions and answers. Confirm eligibility, steps and any fee there before you start.
Before you open them, gather what you are likely to need: your Social Security number, your most recent tax return, and a way to prove who you are. The exact requirements are the IRS's to state, so treat that list as a starting guess and check it against the page.
If your PIN is missing or never showed up, the IRS has a dedicated page for that situation [4]. Keep any IRS letters about your PIN somewhere you can find them.
If you think someone has already filed in your name, our sources do not explain how to report it. Use the identity theft pages on IRS.gov, or talk to a qualified tax professional. This article is educational only and is not legal or tax advice.
