An IRS PIN (Personal Identification Number) is a six-digit security code the Internal Revenue Service assigns to protect your tax account from identity theft and fraud. If someone has stolen your identity or you've been a victim of tax fraud, the IRS may require you to use a PIN when filing taxes electronically. Even if you haven't experienced fraud, you can request one proactively.
This guide explains what an IRS PIN is, who needs one, and how to obtain it.
An IRS PIN serves as an extra layer of security for your tax account. When filing electronically, you'll enter the PIN along with your other filing information. This prevents fraudsters from filing returns in your name, even if they have your Social Security number and personal information.
The IRS issues PINs in two main situations:
The method depends on your circumstances and whether you've already been issued one.
When the IRS detects fraud, they'll mail you a notice with your PIN. Read any IRS correspondence carefully—it will explain your PIN and how to use it. If you've lost or forgotten your PIN, you can retrieve it through IRS.gov using their online tools (available during tax filing season) or by calling the IRS directly.
To request a PIN before fraud occurs, you'll need to verify your identity. The IRS offers several methods:
Online self-selection (during tax season): Visit IRS.gov and use the "IP PIN" tool if you're eligible. You'll answer identity verification questions, and the system will generate a PIN immediately. This is the fastest option.
By mail: Complete Form 15227 (Application for an Individual Taxpayer Identification Number) and mail it to the IRS address listed on the form. This takes longer—typically several weeks.
By phone: Call the IRS at the number listed on your most recent tax return or IRS notice. You'll need to verify your identity through questions about your tax history and personal information.
In person: Visit your local IRS office with valid identification. An IRS representative will help you set up a PIN and verify your information on the spot.
Your path to getting a PIN depends on several factors:
| Factor | Impact |
|---|---|
| Previous IRS contact | If you've filed before, the IRS can verify your identity more easily online. New filers may need to use mail or phone. |
| Identity theft status | If the IRS has already identified fraud, you'll receive your PIN by mail—no request needed. |
| Time sensitivity | Online tools are fastest (immediate), while mail takes 2–4 weeks. |
| Filing season | Online self-selection tools are typically available only during tax season (January–April). |
| Identity verification readiness | You'll need to answer security questions or provide documents, so having your tax history handy speeds the process. |
Regardless of which method you choose, be prepared with:
Having this information organized before you start will make the process faster and smoother.
The IRS will never ask for your PIN by email or phone. If someone contacts you claiming to be the IRS and asking for your PIN, it's a scam. The IRS communicates through mail and official website tools.
Your PIN changes annually if you use one. The IRS will mail you a new PIN each year before tax season, or you can generate one online during the filing season.
Using a PIN doesn't replace other security practices. You should still protect your Social Security number, use strong passwords, monitor your credit, and file early to reduce the window for fraudulent returns.
If you're not sure whether you need a PIN, review any IRS notices you've received. If the IRS sent you a letter about identity theft or fraud, follow the instructions in that letter. Otherwise, requesting a voluntary PIN is optional but increasingly recommended as identity theft remains common.
The right choice about obtaining a PIN depends on your risk tolerance, whether you've experienced fraud before, and how much you value the added security. If you receive an IRS notice mentioning identity theft or a required PIN, follow those instructions closely. If you're considering a voluntary PIN purely for prevention, weigh whether the small administrative effort matches your comfort level with your current tax security practices.
