If you need to retrieve IP PIN information before filing, the missing number may be easier to locate than expected. You might have lost your CP01A notice, enrolled online earlier, or learned while filing that you need the current six-digit number. In most cases, you can retrieve your IRS IP PIN through your IRS Individual Online Account.
Do not reuse last year’s number. The IRS generates a new IP PIN for each calendar year, so the current number belongs on a federal return filed this year, even when the return covers an earlier tax year.
Under IRS guidance, an already-assigned PIN can generally be found online. If account access fails, you may need the IRS reissue process to retrieve IP PIN information before tax filing.
Quick answer: You can retrieve IP PIN information for the current year through your IRS Individual Online Account. Sign in, open your Profile page, and select the IP PIN section. The IRS retrieval instructions explain what to do if account access fails. The number changes each calendar year. If online access fails, use the IRS reissue route rather than Form 15227, which is not for replacing an already-assigned PIN.
Key takeaways
An IRS IP PIN is a six-digit number that helps verify your identity on a federal tax return. You must use the current number issued for the calendar year when you file. The IRS creates a new number each year under its IP PIN rules.
Use the PIN issued for the calendar year when you submit the return, not necessarily the tax year printed on the return. For example, an eligible prior-year return or amended return filed this year generally uses this year’s current IP PIN. Last year’s number is no longer valid.
This timing distinction matters. If you need to retrieve IP PIN information, look for the current six-digit number rather than copying one from an older CP01A notice or prior tax file. Entering an expired number can prevent an electronic return from being accepted, even when the income, deductions, credits, and other return details are correct.
You can retrieve IP PIN information through your IRS Individual Online Account by opening the IP PIN section on your Profile page. The IRS retrieval instructions confirm that location. Your online account provides secure access to the Profile area. If you are unsure which page is official, review this IRS login explanation before entering your credentials.
Use that number, not one saved with an older return.
Some taxpayers who opted into the program online may need to get each new PIN through their account instead of expecting a CP01A notice in the mail every year. That difference matters if you are waiting for a letter that may not arrive.
The IRS generates a new number annually, and current IP PIN access remains available online. For these taxpayers, the IRS Online Account is the primary way to retrieve IP PIN information before filing. Confirm that the number shown is for the current calendar year, then give only that number to the preparer or software completing your federal return.
If you cannot retrieve IP PIN information online, the next step is usually to use the IRS IP PIN assistance route and verify your identity for a possible mailed reissue.
Call 800-908-4490 weekdays from 7 a.m. to 7 p.m. local time. Alaska and Hawaii follow Pacific Time. An assistor must verify your identity; the IRS does not read the PIN by phone. If available, the IRS mails a reissue to the address on file under its reissue guidance. See the IRS phone number guide for calling details.
If the IRS assigned you a PIN, do not use Form 15227 to replace it. That form is for new requests, not a way to retrieve IP PIN information.
| Situation | Best first action | Next result |
|---|---|---|
| Can access IRS account | Open Profile, then IP PIN | View current PIN |
| Cannot access account; phone verification works | Call 800-908-4490 | IRS may mail it |
| PIN belongs to a minor under 18 | Call IRS line | IRS may mail it |
| Reissue unavailable during IRS maintenance | Follow IRS instructions | Paper filing without it may be necessary |
| Assigned PIN; considering Form 15227 | Do not file it | Retrieve online or call |
A mailed reissue follows phone verification. If the IRS confirms your identity and reissue is available, it sends the IP PIN to the address on file within 21 days. The IRS mailing timeline begins after verification, so don’t count those 21 days until you complete the call.
Before waiting for paper mail, first try to retrieve IP PIN information through your online account. Current IP PIN access is generally available during the IRS viewing window, and the number displayed there can be used without waiting for a replacement notice.
| Situation | What timing to expect | When to take action |
|---|---|---|
| Current PIN available online | View it through Online Account during the IRS availability window | Use online retrieval first |
| Phone reissue after identity verification | IRS says it will be mailed within 21 days | Use the phone route when online retrieval is unavailable |
| CP01A recipients | Generally mailed around the IRS annual issuance period | Confirm whether you should expect paper delivery |
| Annual maintenance period | Reissue may be unavailable during the IRS end-of-year maintenance period | Follow current IRS fallback instructions |
If an IP PIN is required and the e-filed return is missing it or contains the wrong number, the IRS can reject the electronic return. Under IRS filing rules, each assigned person needs the current six-digit number.
A paper return without the required PIN follows a different path. The IRS can review your identity before processing the return, which may delay any refund. Mailing the return does not correct the missing IP PIN.
Read the electronic rejection carefully. The reject information can identify whose IP PIN caused the problem:
Once you identify the person named in the rejection, retrieve IP PIN information for that individual and enter the current calendar-year number before resubmitting. Last year’s number, another family member’s PIN, and the five-digit self-select PIN will not correct the same rejection.
| What you may assume | What it actually means |
|---|---|
| "It is my five-digit e-file signature PIN." | No. The IP PIN is a separate six-digit identity-protection number from e-file signing. |
| "Last year's IP PIN should still work." | No. The IRS issues a new current IP PIN each year. |
| "I can use Form 15227 to replace it." | Not after the IRS assigns one. Form 15227 is only for new requests. |
| "It is required for my state return." | The IRS IP PIN applies to specified federal returns. |
| "I need it to file Form 4868." | The IRS says the IP PIN is not used on Form 4868. |
| "My tax preparer can retrieve it for me." | You must retrieve the number and give it to your preparer. |
To retrieve IP PIN information, use the current six-digit IRS-issued number rather than another filing PIN, a prior-year number, or an enrollment form, which cannot fix an e-file rejection.
Each person who has been assigned an IP PIN has a separate number, so a joint return or dependent situation may require more than one current PIN. IRS spouse and dependent rules require separate entries for spouses and assigned dependents. One spouse’s PIN cannot cover both filers.
| Person | What to check when e-filing | Retrieval note |
|---|---|---|
| Primary taxpayer | Enter that taxpayer’s current six-digit PIN in the correct field | The number belongs only to that taxpayer |
| Spouse | Confirm whether the spouse has an assigned PIN and enter it separately | Do not reuse the primary taxpayer’s PIN |
| Dependent | Check whether the IRS assigned the dependent a PIN | An assigned dependent PIN may be required on the e-filed return |
If the missing number belongs to a spouse or an adult dependent, that person generally must retrieve IP PIN information through the applicable IRS route. A different rule can apply to a minor under 18: a lost or non-received PIN cannot be retrieved online under current guidance. Call the IRS for a possible mailed dependent reissue instead.
Retrieving the number itself is generally a taxpayer task, but professional filing help can make sense when the current PIN is correct and the return still rejects or another filing problem remains.
You must retrieve IP PIN information yourself. A preparer cannot do it for you. IRS IP PIN guidance says the PIN is known only to you and the IRS until filing.
Get professional help when:
Tax preparation help can review the rejection, confirm PIN placement, and examine the return. A preparer can address the filing issue after receiving the number, but cannot get the PIN for you.
Open your IRS Individual Online Account, go to Profile, and select the IP PIN section. The current six-digit number appears there. If the IRS sends you a CP01A notice, that notice also contains the PIN, but online enrollees may need to use their account instead.
When online access is unavailable, call the current specialized IRS IP PIN assistance line. You will need to verify your identity. The representative does not read the number over the phone; if reissue is available, the IRS may mail it under its reissue instructions.
Last year’s number will not work. The IRS generates a new PIN each calendar year under its IP PIN FAQs. Use the current number for federal returns filed during that calendar year, including an applicable prior-year return submitted after the new PIN becomes active.
Not receiving CP01A does not always mean the IRS failed to send something you need. Taxpayers who opted into the program online may need to retrieve IP PIN information through their IRS Individual Online Account each year instead of waiting for an annual mailed notice.
An e-filed federal return can be rejected when a required IP PIN is missing or incorrect. You may file on paper without it, but the IRS can hold the return for identity review, slowing processing and any refund. Finding the current number first is usually the faster route.
A lost or non-received PIN for a dependent under 18 cannot be retrieved online under current IRS guidance. To retrieve IP PIN information for the minor, use the specialized IRS reissue procedure. The IRS must verify the caller’s identity before it may mail a replacement.
Before submitting your return, retrieve IP PIN information and confirm the current calendar-year number. Match each PIN to the person who received it. A joint or dependent return may require separate numbers for the taxpayer, spouse, and an assigned dependent.
Enter each PIN where the federal filing process requests it. If online retrieval fails, use the official IRS fallback instead of guessing or reusing an older PIN. These checks follow IRS filing guidance and reduce an avoidable e-file rejection.
A correct PIN does not fix every filing problem. If the number belongs to the right person and the return still rejects, separate the retrieval issue from the larger problem. Tax preparation support can review the rejection, confirm PIN placement, and determine whether another entry needs attention.
