The IRS Identity Protection PIN (IP PIN) is a 6-digit number that enrolled taxpayers must include on their federal return before it can be accepted for e-file. For most preparers, IP PINs show up as a problem only when a client either forgot to mention they have one, or provided last year's PIN instead of the current one. Both situations produce a reject code that blocks transmission until the correct PIN is entered.
This guide covers the preparer-side workflow: adding IP PINs to returns correctly, handling reject codes IND-180 and IND-182, and updating your client intake process to catch IP PIN issues before they delay a return. All IRS rules, code definitions, and program details cited here reflect information as of 2026; verify current policy at IRS.gov before acting on any specific step.
For a broader view of e-file reject codes beyond IP PIN, see the full IRS e-file rejection codes guide. If you are still getting your EFIN set up or building your e-file practice, start there before working through the reject code workflows.
What the IP PIN Does (Preparer Context)
The IP PIN is the IRS's primary identity-layer control for e-filed returns belonging to taxpayers who are at higher risk of SSN fraud. Once a taxpayer is enrolled, the PIN functions as a session credential tied to that specific filing year. As of 2026, the program works as follows (verify current details at IRS.gov):
- Fraud prevention: The PIN prevents someone who has obtained a taxpayer's SSN from filing a fraudulent return in that taxpayer's name. Without the correct current-year PIN, the IRS rejects the return, even if all other data is accurate.
- Required on every return for enrolled taxpayers: If a primary taxpayer, spouse, or dependent is enrolled in the IP PIN program, their PIN must appear on the return for the return to be accepted. Enrollment does not pause between years.
- Annual rotation: The IRS issues a new 6-digit PIN every January. The prior year's PIN is invalid for the current return. A client who used an IP PIN last year must retrieve a new one every filing season.
- Missing or wrong PIN triggers a reject: The IRS returns the transmission with reject code IND-180 (PIN missing) or IND-182 (PIN present but does not match). There is no grace period and no alternative submission path while enrolled.
Taxpayers may be enrolled in the IP PIN program either because they were identity theft victims and the IRS assigned them a PIN automatically, or because they voluntarily opted in at IRS.gov/ippin (verify current enrollment URL at IRS.gov). As of 2026, voluntary enrollment is open to any taxpayer who can verify their identity through the IRS online account system.
One important policy note: as of 2026, there is no opt-out mechanism once a taxpayer is enrolled in the IP PIN program. The IRS has discussed possible policy changes on this point; verify the current opt-out status at IRS.gov before advising clients on whether enrollment is reversible.
Reject Codes IND-180 and IND-182
These are the two reject codes you will see whenever an IP PIN issue prevents transmission. Both are resolvable with the same corrective action, but they signal different underlying problems. Code definitions are as of the 2025-2026 filing season; verify current definitions at IRS.gov or in your software's reject code reference.
IND-180: IP PIN Expected but Not Present
IND-180 means the IRS records show that the taxpayer (or a dependent) is enrolled in the IP PIN program, but no IP PIN was entered on the return at the point of transmission. This is the most common IP PIN reject and almost always happens because the client did not disclose their IP PIN during intake. The return went to the IRS with a data field the IRS expected to be populated -- and it was not.
Resolution: the taxpayer retrieves their current-year IP PIN from IRS.gov/ippin, provides it to you, you enter it in the software, and resubmit the return. See the section below on how clients retrieve their PIN if they do not already have it.
IND-182: IP PIN Present but Does Not Match
IND-182 means an IP PIN was entered on the return, but it does not match the PIN the IRS issued for that taxpayer for the current filing year. The most frequent cause is a client who provided last year's PIN. Because the PIN rotates every January, a 6-digit number that worked last season is always wrong for the current one. A less common cause is a transcription error where the PIN was entered incorrectly.
Resolution: the taxpayer retrieves the correct current-year IP PIN from IRS.gov/ippin. You replace the incorrect PIN in the software with the new one and resubmit. Verify the PIN digit by digit with the client before resubmitting to avoid a second reject.
Practical Reject Workflow for Both Codes
- Identify the reject code in your software's transmission report (IND-180 or IND-182).
- Note which taxpayer or dependent triggered the reject. IND-180 and IND-182 can be triggered by the primary filer, the spouse, or a dependent who is enrolled in the IP PIN program.
- Contact the client and ask them to retrieve their current-year IP PIN from IRS.gov/ippin. Do not accept last year's PIN, even if the client is certain that is the right one.
- Enter the new PIN in the appropriate field in your software. In most professional software, the IP PIN field appears on the personal information or e-file information screen for the primary taxpayer, spouse, and each dependent.
- Resubmit the return. Monitor the transmission acknowledgment for confirmation of acceptance.

How Clients Retrieve Their IP PIN
The IP PIN retrieval process belongs entirely to the taxpayer. You cannot retrieve it for them through IRS.gov/ippin -- the portal requires the taxpayer to authenticate with their own IRS online account credentials. What you can do is walk a client through the options and tell them which one applies to their situation. As of 2026, there are three retrieval paths (verify current availability at IRS.gov):
Option 1: IRS.gov/ippin (Online Self-Service)
The fastest path for most clients. The IRS opens the IP PIN portal each January, and enrolled taxpayers can log in with their IRS online account to retrieve the current year's PIN. The client will need their IRS account credentials (username and password for IRS.gov, or ID.me-verified login). If the client has not previously created an IRS online account, they will need to complete identity verification through ID.me before they can access the portal.
Verify the current URL and portal availability at IRS.gov, as the IRS has updated access paths in prior years.
Option 2: IRS Phone Line
Clients who cannot use the online portal can call the IRS to request their IP PIN by phone. The IRS will verify the client's identity before providing the PIN. Wait times at IRS phone lines can be substantial, particularly during peak filing season. Advise clients to call early in the day and to have their Social Security Number, prior-year tax return information, and mailing address ready for verification.
Verify the current IRS phone number for IP PIN assistance at IRS.gov, as IRS contact numbers and procedures are subject to change.
Option 3: IRS Taxpayer Assistance Center (In-Person)
Clients who cannot complete online or phone verification can visit an IRS Taxpayer Assistance Center (TAC) in person. The client will need to bring valid government-issued photo identification and will go through in-person identity verification. TAC appointments can be limited during filing season, so clients should schedule as early as possible.
Locate the nearest Taxpayer Assistance Center and schedule an appointment at IRS.gov.
A Note on Preparer Authorization
If you hold a valid Power of Attorney for a client via Form 2848, you may be able to act on certain matters on the client's behalf, but the IRS.gov/ippin self-service portal is taxpayer-authenticated and does not accommodate third-party access. Verify with the IRS what actions a Form 2848 holder can take in the IP PIN context before attempting to act as a client's representative for PIN retrieval.
For most practitioners, the practical answer is: the client retrieves the PIN, the client provides it to you, and you enter it and resubmit. If the client cannot retrieve the PIN through any of the three channels above, the return cannot be e-filed until the PIN issue is resolved. A paper filing may be the only path for clients who are completely unable to retrieve their PIN before a deadline; consult IRS guidance on this scenario and verify current IRS policy at IRS.gov.
Updating Your Client Intake Process
The most efficient way to handle IP PINs is to collect them before the client sits down with you, not after a rejection forces a second contact. A small change to your organizer and your pre-season communications eliminates most IP PIN delays. The following language is meant as a starting point; adapt it to fit your practice's intake format.
Add an IP PIN Question to Your Client Organizer
Include this question for every client, not just returning clients who you know had a PIN in prior years. New clients may have been enrolled during the prior year without your knowledge, and identity theft victims may be enrolled automatically by the IRS:
"Have you, your spouse, or any of your dependents received an IRS Identity Protection PIN (IP PIN) for the 2025 tax year? If yes, please provide each 6-digit PIN. Your IP PIN was mailed or made available through your IRS online account in January 2026. It is different from last year's PIN."
The language "It is different from last year's PIN" directly addresses the most common source of IND-182 rejects: clients who believe the PIN they already have is valid for the current year.
Reminder Language for Returning Clients
If a client had an IP PIN on their prior-year return, flag them in your practice management system and include a targeted reminder in your pre-season communication. The reminder does not need to be long. Something like the following added to your January outreach covers it:
"Based on your prior-year return, you have an IRS Identity Protection PIN on file. Please retrieve your current 2025 IP PIN from IRS.gov/ippin before your appointment. The PIN from last year will not work for this year's return."
Clients who receive this before the appointment arrive with the correct PIN in hand rather than discovering the gap mid-appointment.
Track IP PIN Status in Your Client Records
After you enter an IP PIN on a client's return, note in your practice management system that the client is enrolled in the IP PIN program. A simple flag or field update means you do not have to rely on the client to self-report in future years. This also feeds your pre-season reminder workflow automatically each January. Protecting this information is part of your broader client data security obligations. For the data security requirements that apply to your office, see the data security guide for tax preparers.
IP PINs for Dependents
Dependents can be enrolled in the IP PIN program, and their enrollment is entirely independent of the primary taxpayer's enrollment. A dependent may have an IP PIN even when the parent or guardian does not, and vice versa. This is the part of the IP PIN workflow that catches the most preparers off guard.
When a Dependent IP PIN Is Required
As of 2026, if a dependent is enrolled in the IP PIN program, their PIN must be entered on the return for any credit claim that references that dependent, including the Earned Income Tax Credit (EITC), Child Tax Credit (CTC), and American Opportunity Tax Credit (AOTC). Verify current requirements at IRS.gov, as the specific credits subject to this requirement may change.
Children are a particularly high-risk group for SSN theft because their Social Security Numbers are often targeted by fraudsters long before the child files their first tax return. A client's child may have been enrolled in the IP PIN program by the IRS as a fraud prevention measure, and the parent may not realize it or may not have thought to mention it.
IND-180 and IND-182 Triggered by a Dependent
The same reject codes that flag primary taxpayer IP PIN issues also fire when a dependent's IP PIN is missing or incorrect. The reject message will typically identify which taxpayer on the return triggered the code. If you see IND-180 or IND-182 and the primary taxpayer's PIN is correct, check whether a dependent on the return has an IP PIN requirement.
Resolution follows the same path: the taxpayer (or the parent or guardian acting on behalf of a minor dependent) retrieves the dependent's current-year IP PIN from IRS.gov/ippin, and you enter it in the dependent's IP PIN field in your software.
Connection to EITC Due Diligence
IP PIN issues on dependents surface most frequently on returns that claim the Earned Income Tax Credit, because EITC claims attract heightened IRS scrutiny and because EITC-eligible families often include children who are enrolled in the IP PIN program due to prior SSN fraud. Your EITC due diligence checklist should include an explicit IP PIN question for each qualifying child claimed. For the full due diligence requirements that apply to EITC claims, see the EITC due diligence requirements guide.
Asking about dependent IP PINs as part of your Form 8867 intake process, rather than treating it as a separate step, keeps the question in context and reduces the chance it gets overlooked.
Frequently Asked Questions: IP PIN for Tax Preparers
What is an IRS IP PIN and when does a tax preparer need it?
An IRS Identity Protection PIN (IP PIN) is a 6-digit number issued annually to taxpayers enrolled in the IP PIN program (as of 2026; verify current program details at IRS.gov). Once a taxpayer is enrolled, the IP PIN must be entered on their federal return before the IRS will accept it for e-file. A preparer needs it every filing year for any client who is enrolled. A new PIN is issued each January, so the prior year's PIN is always invalid for the current return. Clients who are enrolled may be identity theft victims who were automatically enrolled by the IRS, or taxpayers who opted in voluntarily at IRS.gov.
What does reject code IND-180 mean?
Reject code IND-180 means an IP PIN was expected on the return but was not present (as of the 2025-2026 filing season; verify current code definitions at IRS.gov). This typically happens when a client did not tell their preparer about the IP PIN during intake, or when the preparer did not enter it in the software before transmitting. Resolution: the taxpayer retrieves their current-year IP PIN from IRS.gov/ippin, provides it to the preparer, the preparer enters it in the software, and the return is resubmitted.
What does reject code IND-182 mean?
Reject code IND-182 means an IP PIN was entered on the return but does not match the PIN the IRS issued for that taxpayer for the current filing year (as of the 2025-2026 filing season; verify current code definitions at IRS.gov). The most common cause is the client providing last year's PIN instead of the current one. The resolution is the same: the taxpayer retrieves the correct current-year IP PIN from IRS.gov/ippin, the preparer replaces the incorrect PIN in the software, and resubmits. Verify the PIN digit by digit with the client before resubmitting.
Can a tax preparer retrieve a client's IP PIN?
No. A tax preparer cannot retrieve a client's IP PIN through IRS.gov/ippin on the client's behalf. The self-service portal requires the taxpayer to authenticate with their own IRS online account. Holding a valid Power of Attorney via Form 2848 may allow certain actions on a client's behalf, but does not grant access to the taxpayer-authenticated IP PIN portal. Verify what a Form 2848 holder can do in the IP PIN context directly with the IRS. For most situations, the practical workflow is: the client retrieves the PIN through the portal, by phone, or at a Taxpayer Assistance Center, then provides it to the preparer.
What happens if a client with an IP PIN cannot access IRS.gov?
If a client cannot use the IRS.gov/ippin online portal, they have two additional options as of 2026 (verify current availability and procedures at IRS.gov): calling the IRS to request the PIN by phone with identity verification, or visiting an IRS Taxpayer Assistance Center in person with valid photo ID. The return cannot be e-filed without the correct current-year IP PIN, so resolving the client's access issue is the necessary first step. In rare situations where the client cannot retrieve the PIN through any channel before a deadline, a paper filing may be the only available path. Consult current IRS guidance on that scenario at IRS.gov before advising a client to file on paper.
