IRS Reject Code IND-181-01: primary taxpayer IP PIN

What does IRS reject code IND-181-01 mean?

IND-181-01 is an e-file rejection tied to the primary taxpayer's Identity Protection PIN. The IRS requires the correct six-digit IP PIN when one has been assigned or requested for that taxpayer.

This is different from the five-digit Self-Select PIN used for an electronic signature and different from a prior-year AGI rejection.

What is an IRS IP PIN?

An Identity Protection PIN is a unique six-digit number the IRS uses to help verify a taxpayer's identity and reduce the risk of fraudulent federal tax returns. A new IP PIN is generated each year.

Which IP PIN should I use?

Use the IP PIN that is valid for the current calendar year in which you are filing. The IRS says the current IP PIN is also used for prior-year federal returns filed during that same calendar year.

Do not use last year's IP PIN simply because you are filing last year's tax return.

Why can IND-181-01 happen?

• The IP PIN was typed incorrectly.
• The IP PIN is incomplete.
• An older IP PIN from a prior calendar year was entered.
• The primary taxpayer's IP PIN was placed in the wrong taxpayer field.
• The taxpayer has an IP PIN requirement but the correct number was not available when the return was prepared.

How do I retrieve a lost or missing IP PIN?

The IRS says taxpayers who have an IP PIN can generally retrieve the current number through their IRS Online Account. Depending on how the taxpayer enrolled, the IRS may also issue a CP01A notice by mail.

If you cannot access the current IP PIN online, follow the IRS recovery instructions rather than guessing the number.

How do I fix IND-181-01?

1. Save the complete rejection message. Confirm the code is IND-181-01.
2. Confirm the person. This code concerns the primary taxpayer.
3. Retrieve the current IP PIN. Use the six-digit IP PIN issued for the current calendar year.
4. Check all six digits carefully. Do not confuse the IP PIN with the five-digit electronic-signature PIN.
5. Enter the IP PIN in the primary taxpayer's IP PIN field.
6. Review the return for other reject codes.
7. Resubmit and check the new acknowledgment.

What if I am filing a prior-year return?

Use the IP PIN for the current calendar year, even when filing a prior-year federal return during that year. The IRS specifically says the current IP PIN is used on current and prior-year returns filed during the same calendar year.

What if I file without my IP PIN?

The IRS says an e-filed return can be rejected when a required IP PIN is missing or incorrect. A paper return filed without the IP PIN may be subject to additional identity verification and processing delays.

IND-181-01 vs. IND-183-01

IND-181-01 concerns the primary taxpayer's IP PIN. IND-183-01 concerns the spouse's IP PIN. If the rejection is IND-183-01, review the spouse's own six-digit IP PIN instead.

Common questions about IND-181-01

Is an IP PIN the same as my electronic filing PIN?

No. The IRS IP PIN has six digits. A Self-Select PIN used to sign an electronic return has five digits.

Do I get a new IP PIN every year?

Yes. The IRS generates a new IP PIN each year.

Can I use last year's IP PIN?

No. Use the IP PIN issued for the current calendar year in which the federal return is being filed.

Does IND-181-01 mean someone stole my identity?

Not necessarily. Taxpayers may have an IP PIN because of prior identity-theft protection or because they voluntarily enrolled in the IRS IP PIN program. The reject code itself only tells you that the primary taxpayer's IP PIN did not validate.
