If you live and work in the United States but don't have a Social Security number, you still have the right — and often the obligation — to file a federal tax return. An Individual Taxpayer Identification Number (ITIN) makes that possible. This guide explains exactly how ITIN filing works, what you stand to gain, and how to get it done correctly.
What Is an ITIN — and Who Needs One?
An ITIN is a nine-digit tax identification number issued by the IRS to people who are not eligible for a Social Security number (SSN) but need to fulfill U.S. tax obligations. According to the IRS, ITINs are issued regardless of immigration status — meaning both documented and undocumented residents can apply.
You may need an ITIN if you are:
- A nonresident or resident alien required to file a U.S. federal tax return
- A foreign national on a student, investor, or work visa who doesn't qualify for an SSN
- A dependent or spouse of a U.S. citizen or lawful permanent resident
- A spouse or dependent of a visa holder
- Self-employed, freelancing, or earning business income in the U.S.
ITINs always begin with the number 9 and follow the same 9-digit format as an SSN (9XX-XX-XXXX). Critically, an ITIN is not a work permit, does not grant immigration status, and cannot be used to claim Social Security benefits. Its purpose is strictly federal tax filing — though it unlocks several important secondary benefits, as explained below.
Why Should Immigrants File Taxes? The Benefits May Surprise You
Many immigrants are uncertain whether filing taxes makes sense without legal status or an SSN. In fact, there are compelling reasons to file — beyond the legal obligation:
1. Building a Tax History A history of filed tax returns is one of the few ways to document how long you have been present and financially contributing in the United States. Immigration attorneys regularly advise clients to maintain complete tax records as evidence of good moral character and extended U.S. residence — factors that matter in future immigration proceedings.
2. Potential Tax Refunds ITIN filers who overpay through withholding or estimated payments are entitled to refunds. Filing is the only way to claim money owed to you.
3. Opening a Bank Account Many banks and credit unions accept an ITIN in place of an SSN to open a checking or savings account. This is a foundational step toward building credit and financial stability in the U.S.
4. Claiming Dependents and Allowable Credits ITIN filers may be eligible for the Child Tax Credit (for qualifying children who have SSNs), education credits, and other allowable deductions that can reduce what you owe.
5. Avoiding Penalties If you are required to file — because you have U.S.-source income above the filing threshold — not filing exposes you to IRS failure-to-file penalties, which accrue monthly and compound quickly.
According to the American Immigration Council, in 2022 alone, approximately 3.8 million tax returns included an ITIN, with filers paying billions in federal taxes. Filing taxes is a demonstration of civic participation that immigrants' communities have made consistently for decades.
Step 1: Apply for Your ITIN (Form W-7)
To get an ITIN, you must complete IRS Form W-7 — the Application for IRS Individual Taxpayer Identification Number. Key steps:
What you need:
- A completed federal tax return (Form 1040 or 1040-NR) — you submit the return with your W-7 application, not separately
- Proof of foreign status and identity — a valid passport is the only standalone document accepted; other combinations include a national ID card + birth certificate, or a visa + foreign voter registration card
- If applying for a dependent, proof of U.S. residency may also be required
How to apply:
| Method | Best For | Documents Required |
|---|---|---|
| Mail (IRS Austin, TX) | Anyone with certified copies | Certified copies of originals; originals mailed back |
| IRS Taxpayer Assistance Center (TAC) | Anyone; in-person verification | Original documents; returned same day |
| Certifying Acceptance Agent (CAA) | Best option for most filers | Agent certifies documents; you keep originals |
A Certifying Acceptance Agent (CAA) is a tax professional authorized by the IRS to authenticate your original identity documents on-site, so you never have to mail your passport or birth certificate to Austin. This is the safest, most convenient route for most people. Dynamic Tax & Accounting Services helps clients through the CAA process at our Bronx, Queens, and New Jersey offices — call (646) 295-3811 or visit dynamicsrv.com to schedule an appointment.
How long it takes: The IRS generally processes ITIN applications within 7 to 11 weeks. Apply early — before the April 15 filing deadline — to avoid extension filing.
Step 2: File Your Federal Tax Return
Once you have your ITIN, you file your taxes using the same forms as any other U.S. taxpayer:
- Form 1040 — for resident aliens and most filers living and working in the U.S.
- Form 1040-NR — for nonresident aliens with U.S.-source income (rental income, investment income, limited work)
Which forms apply to your income type:
| Income Type | Key Form |
|---|---|
| Wages (W-2 from employer) | Form 1040, Line 1 |
| Self-employment / freelance / gig work (1099-NEC) | Schedule C + Schedule SE |
| Rental income | Schedule E |
| Interest / dividends | Schedule B |
If you are self-employed — driving for Uber, Lyft, or DoorDash, doing construction, childcare, cleaning, or any freelance work — you will file Schedule C to report profit or loss from your business and Schedule SE to calculate your self-employment tax (15.3% of net earnings). You may owe this tax even if your total income is modest, so working with a tax professional is especially important.
Common Deductions That ITIN Filers Often Miss
Because many immigrant workers are self-employed or in the gig economy, they qualify for business deductions that significantly reduce what they owe. Common deductions include:
- Mileage — if you drive for work (Uber, delivery, construction site visits), you can deduct 70 cents per mile driven in 2025
- Phone and internet — the portion used for work is deductible
- Tools, uniforms, equipment — anything required specifically for your job
- Home office — if you run a business from a dedicated space in your home
- Health insurance premiums — 100% deductible for the self-employed
- Half of your self-employment tax — always deductible on Form 1040
Additionally, if you have children with valid SSNs, you may be eligible for the Child Tax Credit even as an ITIN filer — a benefit worth up to $2,000 per qualifying child. Many ITIN filers do not claim this credit, leaving significant money unclaimed.
New York and New Jersey State Tax Filing with an ITIN
If you live in New York or New Jersey, you also need to file state taxes:
- New York State: File Form IT-201 (residents) or IT-203 (part-year/nonresidents). New York accepts ITINs for state filing. NYC residents pay an additional city income tax.
- New Jersey: File Form NJ-1040. New Jersey also accepts ITINs for state returns.
State filing deadlines match the federal deadline (April 15 for most filers). New York and New Jersey both allow payment plans if you owe but can't pay in full.
What Happens If Your ITIN Expires?
ITINs that have not been used on a federal tax return for three consecutive years expire automatically. Additionally, ITINs with certain middle digits are subject to IRS renewal cycles. If your ITIN has expired, you must renew it by submitting a new Form W-7 before or when you file your next return. A tax professional can verify whether your ITIN is still active.

Frequently Asked Questions
Can I get a tax refund with an ITIN? Yes. If you have overpaid through withholding or estimated payments, the IRS will issue a refund to your ITIN, just as it would for an SSN holder.
Does filing taxes with an ITIN affect my immigration case? Generally, filing taxes demonstrates good moral character and consistent U.S. presence, which can be beneficial in immigration proceedings. However, individual circumstances vary — consult an immigration attorney for advice specific to your case.
Can my family members get ITINs too? Yes. Spouses and dependents who are not eligible for SSNs can also apply for ITINs, which allows them to be claimed on your tax return for credits and exemptions.
I haven't filed taxes for several years — is it too late? No. The IRS accepts prior-year returns, and filing late is almost always better than not filing at all. Dynamic Tax can help you prepare and file back taxes, minimize penalties, and get you into compliance.
