Apply For or Renew Your ITIN Number
Introduction
An ITIN number is essential for individuals who need to file U.S. tax returns but are not eligible for a Social Security Number. This commonly includes non-residents, foreign investors, dependents, and spouses who have U.S. tax obligations.
Many applicants face confusion during ITIN application or renewal. This guide explains how to apply for or renew an ITIN, the documents required, and how EbizFiling helps ensure the process is completed correctly.
What Is an ITIN Number?
An ITIN Number (Individual Taxpayer Identification Number) is a 9-digit tax identification number issued by the IRS. It is used only for federal tax purposes.
ITINs are issued to individuals who do not qualify for an SSN but still have U.S. tax obligations, such as filing tax returns or claiming treaty benefits.
Who Needs an ITIN?
- You may need an ITIN if you are:
- A non-resident filing U.S. tax returns
- A foreign investor earning U.S. income
- A dependent or spouse of a U.S. taxpayer
- A foreign partner in a U.S. business
How to Apply for a New ITIN Number?
To apply for a new ITIN number, you must submit Form W-7 along with supporting documents.
Documents Required
- Completed Form W-7
- Original U.S. federal tax return (unless exempt)
- Valid passport or two IRS-approved ID documents
- Proof of foreign status
- A passport alone is sufficient. Otherwise, multiple documents are required.
Ways to Submit Your ITIN Application?
- By Mail: You can mail your Form W-7, tax return, and original documents to the IRS ITIN Operations office. Documents are returned within approximately 60 days.
- In Person: You can visit an IRS Taxpayer Assistance Center that offers ITIN services. Documents are verified and returned immediately.
- Through an Authorized Agent: Using an IRS-authorized Certifying Acceptance Agent allows document verification without mailing originals.
ITIN Processing Time
The IRS generally takes 7 to 11 weeks to process an ITIN application. During peak tax season, processing may take longer.
How to Renew an Expired ITIN?
You must renew your ITIN if:
It has not been used for three consecutive tax years
It falls under IRS middle-digit expiration rules
Renewal Steps
- Complete Form W-7 and select the renewal option
- Attach a tax return unless exempt
- Submit identity documents
- File via mail, TAC, or authorized agent
Using an expired ITIN can delay tax refunds and disallow credits.
Penalties and Risks of Not Renewing ITIN
Filing a tax return with an expired ITIN may result in:
- Processing delays
- Refund holds
- Loss of tax credits
Timely renewal avoids these issues.
