What Happens When Your ITIN Expires? Consequences and Next Steps

What Triggers an ITIN to Expire in 2026?

The IRS expires ITINs through two pathways. First, any ITIN not used on a federal tax return for three consecutive tax years expires automatically on December 31 of the third year. Second, the IRS retires ITINs in batches by middle digits. The current retired ranges as of 2026 cover middle digits 70 through 88 and 90, 92, 94, 95, 96, 97, 98, 99. An ITIN matching either trigger is invalid until renewed.

What Happens to a Tax Return Filed With an Expired ITIN?

• Return processing pauses. The IRS treats the ITIN as missing.
• Refund is held until the ITIN is renewed.
• Refundable credits are denied for the tax year if the ITIN was expired on the return due date.
• E-file is rejected. Most software flags the expired ITIN before submission.
• Notice CP48 or CP567 is sent to the address on file explaining the issue.

For the full renewal checklist, see the ITIN expiration guide.

Does an Expired ITIN Cause Penalties or Interest?

The IRS does not assess a separate penalty for expired ITINs. However, if the return was filed late because of the expiration, standard failure-to-file and failure-to-pay penalties may apply to any balance due. Interest accrues on unpaid tax until the balance is paid. Refund returns face no penalty, only delay.

Can an Expired ITIN Still Be Used for Banking or Credit?

Banks and credit bureaus use the ITIN as a unique identifier and do not query the IRS for renewal status. Existing accounts, credit files, and loans continue to function. However, opening new accounts that require IRS verification (such as some brokerage accounts or W-9 onboarding) may be rejected until the ITIN is renewed. Treat the expired ITIN as a tax-only problem, not a banking shutdown.

How Do You Renew an Expired ITIN With the IRS?

1. Confirm expiration. Check the middle digits against the current retired list or count years since last use.
2. Complete Form W-7 with the renewal box checked. No tax return is required for a renewal-only filing.
3. Gather supporting documents. Passport or two alternative documents proving identity and foreign status.
4. Choose submission channel. CAA (recommended, no passport mailing), IRS Austin TX address, or an in-person TAC appointment.
5. Wait 7 to 11 weeks for the CP565 with the same ITIN number reactivated.

How Can ITIN Holders Avoid Future Expiration?

File at least one federal tax return every three years naming the ITIN. This includes dependents and spouses listed on another taxpayer's return. Track the middle digits annually against the IRS retired list published each fall. ITINs renewed in the prior 12 months are not part of the annual digit retirement cycle, so a fresh renewal protects against the immediate next batch.
