Late ITIN Renewal Delays Refunds for 2025 Filers

As the 2025 tax season approaches the federal tax filing deadline, some taxpayers are discovering that their Individual Taxpayer Identification Numbers have expired only when preparing a federal tax return. Late ITIN renewal requests submitted to the Internal Revenue Service can slow tax processing and delay refunds, especially for households expecting refundable credits.

IRS Sees Surge in ITIN Renewal Requests During Tax Season

During tax season, the Internal Revenue Service receives a noticeable increase in requests for Individual Taxpayer Identification Numbers as taxpayers prepare a U.S. federal income tax return. Many filers only notice the expiration date of their Individual Tax Identification Number while gathering tax records or completing forms needed for a federal tax return.

The U.S. Internal Revenue Service issues Individual Taxpayer Identification Numbers for federal tax purposes to individuals who are not eligible for a Social Security Number. These identification numbers allow resident aliens and nonresident aliens to file federal income tax returns and comply with U.S. tax laws, even if they cannot obtain a Social Security Number.

Taxpayers apply for or renew these numbers using IRS Form W-7, titled Application for IRS Individual Taxpayer Identification Number. The application process requires supporting documentation such as a birth certificate, civil birth certificate, national identification document, state identification card, foreign driver's license, or consular identification card to confirm identity and foreign status.

Expiration Rules Often Trigger Renewing ITINs Late

Under the Protecting Americans from Tax Hikes Act, known as the PATH Act, an Individual Taxpayer Identification Number expires if it is not used on a U.S. federal tax return for three consecutive tax years. Taxpayers who skipped filing during that period may only realize the number has expired when preparing an income tax return near the tax filing deadline.

When this happens, the IRS requires a Form W-7 renewal along with the U.S. federal income tax return. The renewal process follows the Instructions for Form W-7 and guidance in IRS Publication 1915, Información Para Entender su Número de Identificación Personal del Contribuyente, which explains ITIN rules and documentation requirements.

Another situation occurs when a spouse or dependent needs an Individual Taxpayer Identification Number. Taxpayers claiming tax credits such as the Child Tax Credit, Credit for Other Dependents, American Opportunity Tax Credit, or Premium Tax Credit must ensure each person listed on the federal tax return has a valid taxpayer identification number.

Expired ITINs Can Delay Refunds and Tax Processing

If a federal tax return is filed with an expired Individual Taxpayer Identification Number, the Internal Revenue Service generally accepts the return but pauses tax processing until the renewal process is completed. This delay can affect refunds for refundable credits, including the Child Tax Credit and credits calculated on Schedule 8812 or Form 8863.

During the review period, the return may be routed to ITIN Operations for verification. The agency must verify identity documents and determine whether the application for a taxpayer identification number meets federal tax requirements before issuing a refund.

These delays can affect taxpayers who depend on timely refunds to cover expenses or manage bank account balances. In some cases, additional documentation, such as a marriage certificate, court order, or other supporting documentation, may be required if the taxpayer reports a name change or updates information linked to tax records.

Taxpayers Can Verify ITIN Status Before Filing

Tax professionals and accounting firms advise taxpayers to verify the status of Individual Taxpayer Identification Numbers before filing a federal tax return. Checking the expiration date early can help avoid delays in tax processing and refund payments during the busiest weeks of tax season.

Applicants who need to renew an ITIN must submit IRS Form W-7 with required identification documents and a federal tax return. Some taxpayers visit an IRS Taxpayer Assistance Center or work with Certified Acceptance Agents and Certifying Acceptance Agents who assist with document review and help complete the application process.

Community programs such as VITA sites and Low Income Taxpayer Clinics may also help taxpayers prepare forms like Form 1099 or Form 13614-C and worksheets such as a self-employment worksheet or a medical expenses worksheet, while ensuring the correct identification number appears on the U.S. federal tax return.
