FAQ
ITIN (Individual Taxpayer Identification Number) is a personal taxpayer identification number in the USA, which is issued to non-residents for tax reporting and income tax purposes.
An ITIN is needed for anyone who is not a U.S. citizen and is not eligible for a Social Security Number. The most common reasons include:
- Filing tax returns and paying taxes;
- Requiring a foreign spouse, children or dependents on a tax return;
- Opening a bank account in the U.S. (personal or commercial);
- Opening a business or becoming a member of an LLC;
- Owning and investing in real estate in the United States;
- Eligibility for a reduced tax withholding rate under a tax treaty;
- Applying for a job with a U.S. employer, mortgage or credit card, renting an apartment, etc;
ITIN is issued to non-residents subject to U.S. taxation requirements and not eligible for an SSN.
The application for the ITIN number package includes:
● A completed Form W-7.
● Original identification documents or certified copies issued by a Certified Acceptance Agent.
● A completed U.S. tax return (may not be required for some cases).
● Other documentation for exemptions (if applicable).
Yes, you can get certified copies of your foreign identification at the U.S. Embassy. However, you will still have to fill out a W-7 and collect all the necessary documents yourself. Most ITIN applications are rejected because of errors in the W-7 form. To avoid the risk of rejection, use a certified IRS intake agent to make sure your application for ITIN number is submitted correctly the first time!
TINs that have not been included on your U.S. federal tax return at least once in the last three consecutive tax years will expire. If your ITIN has not been included on your tax return at least once for tax years 2019, 2020 or 2022, your ITIN will expire on December 31, 2022.

No, you do NOT need to send your original passport to the IRS if you are working with a Certified Acceptance Agent. Since we are a Certified Acceptance Agent, we will certify a copy of your passport, so you do not have to send the original.
No, the IRS only accepts original documents or certified copies. The IRS can keep your original documents for up to 60 days, but E-Commerce.One is an IRS Certified Acceptance Agent (CAA) and can provide certified copies with your application.
The ITIN is the counterpart to the SSN and is issued to non-residents who are subject to US tax requirements and are not eligible for an SSN.
All three numbers are unique identifiers (Tax Id) for taxpayers, but differ as follows:
- ITIN — For non-residents filing U.S. taxes.
- EIN — For businesses and employers.
- SSN — For U.S. residents and citizens.
