Quick answer: The IRS says IND-183-01 occurs when the spouse's SSN has an associated IP PIN and the spouse did not enter a valid six-digit IP PIN. Retrieve the spouse's current IP PIN, enter it in the spouse field, correct any other errors and resubmit.

What does IRS reject code IND-183-01 mean?

IND-183-01 is an e-file rejection for the spouse on a return. It means the spouse did not provide a valid IRS Identity Protection PIN even though the spouse's SSN has an IP PIN associated with it.

Which IP PIN should the spouse use?

The spouse must use the current six-digit IP PIN issued for that spouse. A taxpayer's IP PIN cannot be substituted for a spouse's IP PIN.

The IRS generates a new IP PIN every year. The current calendar-year IP PIN must be used on federal returns filed during that year, including prior-year returns.

Why can IND-183-01 happen?

  • The spouse's IP PIN was entered incorrectly.
  • An older IP PIN from a prior calendar year was used.
  • The primary taxpayer's IP PIN was entered in the spouse field.
  • The spouse's six-digit IP PIN was confused with a five-digit Self-Select PIN.
  • The spouse has an IP PIN requirement but the number was left blank.

How can the spouse retrieve a lost IP PIN?

The spouse can generally retrieve the current IP PIN through their IRS Online Account. Taxpayers enrolled because of identity theft may also receive a CP01A notice by mail. If the spouse cannot retrieve the PIN online, follow the IRS recovery instructions rather than guessing the number.

How do I fix IND-183-01?

  1. Save the complete rejection message. Confirm the code is IND-183-01.
  2. Confirm the person. This code applies to the spouse.
  3. Retrieve the spouse's current IP PIN.
  4. Check all six digits carefully.
  5. Enter the spouse's IP PIN in the spouse IP PIN field.
  6. Review the return for any additional reject codes.
  7. Resubmit and check the new IRS acknowledgment.

What if both spouses have IP PINs?

If both taxpayers on a joint return have IP PINs, both IP PINs must be entered in the appropriate taxpayer and spouse fields. Each person uses their own six-digit number.

What if we are filing a prior-year return?

Use the IP PIN issued for the current calendar year, even if the federal return being filed is for a prior year.

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

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, focus on the spouse's own six-digit IP PIN.

Common questions about IND-183-01

Can I use my IP PIN for my spouse?

No. Each taxpayer who has an IP PIN must use their own six-digit IP PIN.

Is an IP PIN the same as a Self-Select PIN?

No. An IRS IP PIN has six digits. A Self-Select PIN used as an electronic signature has five digits.

Does the spouse get a new IP PIN every year?

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

Does IND-183-01 mean identity theft happened this year?

Not necessarily. A taxpayer can have an IP PIN because of prior identity-theft protection or because they voluntarily joined the IRS IP PIN program. The rejection only tells you that the spouse's IP PIN did not validate.
