Across South Florida, hundreds of thousands of people work, raise families, pay rent, and run small businesses without a Social Security number. Many of them assume that because they can't get an SSN, the tax system isn't for them — that filing is either impossible or unsafe. Both assumptions are wrong, and both can be expensive.
The Internal Revenue Service created the Individual Taxpayer Identification Number (ITIN) precisely for this situation: a number that lets someone who isn't eligible for an SSN still file a federal tax return, report income, and — in many cases — claim refunds and credits worth thousands of dollars. For a family in Broward County, getting an ITIN right can be the difference between leaving money on the table every spring and building a clean record of tax compliance that matters for years to come.
This guide walks through what an ITIN is and is not, who needs one, how to apply for or renew it, and — the part that trips up the most families — exactly which tax credits an ITIN unlocks in 2026 after the recent law changes, and which it doesn't.
Key takeaways
- An ITIN is for federal tax purposes only. It does not authorize work, change your immigration status, or qualify you for Social Security benefits.1
- You apply with Form W-7, usually filed together with your tax return; a Certifying Acceptance Agent can verify your passport so you don't have to mail the original to the IRS.2
- The Child Tax Credit requires the child to have an SSN, and starting in 2025 the parent claiming it must have a work-eligible SSN too — though on a joint return, only one spouse needs one.46
- ITIN holders cannot claim the Earned Income Tax Credit, but an ITIN-holding child can still qualify a family for the $500 Credit for Other Dependents.54
- An ITIN expires if it isn't used on a federal return for three years in a row — and must be renewed before you file again.3
1. What an ITIN is — and what it isn't
An Individual Taxpayer Identification Number is a nine-digit tax-processing number the IRS issues to people who have a U.S. tax filing or reporting obligation but are not eligible for a Social Security number. It always begins with the digit 9 and is formatted like an SSN (9XX-XX-XXXX).1 Its entire purpose is to let the tax system identify a taxpayer who would otherwise have no number at all.
What surprises many people is how narrow that purpose is. An ITIN exists for federal tax administration and nothing else. Understanding the limits is just as important as understanding the uses:
What an ITIN does NOT do
An ITIN does not authorize you to work in the United States, does not provide eligibility for Social Security benefits, and does not change or confer any immigration status. Having one — or using one to file — is not, by itself, evidence of unlawful presence, and it is not a substitute for work authorization. It is a tax number, full stop.1
So why get one? Because if you have income that's taxable in the United States, the law requires you to report it, and you need a taxpayer number to do that. Filing with an ITIN lets you meet that obligation, recover federal income tax that may have been withheld from your pay, claim the credits you're legally entitled to, and build a documented history of tax compliance — something that can carry weight far beyond tax season.
2. Who needs an ITIN
You generally need an ITIN if you have a U.S. tax filing requirement (or are entitled to a refund) and you are not eligible for an SSN. In South Florida, the people who most often need one fall into a handful of recognizable groups.
| Who | Why they typically need an ITIN |
|---|---|
| Workers without an SSN | They earn income in the U.S. and must file a return, but aren't eligible for a Social Security number. |
| Spouses and dependents | A spouse or child who needs to be listed on a return — for example to file jointly or to claim a dependent — but has no SSN. |
| Small-business owners & landlords | People with U.S. business or rental income that must be reported, including some foreign owners of U.S. property. |
| Investors with U.S.-source income | Nonresidents who receive income subject to U.S. tax or reporting and need a number to file or claim a treaty benefit. |
| Students & scholars | Certain foreign students, professors, or researchers who must file but can't get an SSN. |
One important note: you cannot have both an SSN and an ITIN. If you are eligible for a Social Security number, you must apply for that instead — the ITIN is only for people who are not eligible. And if you later become eligible for an SSN (for example, after a change in immigration status), you should stop using the ITIN and notify the IRS so your tax records can be merged.
3. How to apply for (or renew) an ITIN
You apply for an ITIN using Form W-7, the Application for IRS Individual Taxpayer Identification Number. In most cases you submit the W-7 together with the federal tax return for which you need the number, plus documents that prove both your identity and your foreign status.2
The documentation step is where families get nervous — and for good reason. The default process asks you to mail original documents, such as your passport, to the IRS, where they may sit for weeks. There are safer ways to do it:
- Use a Certifying Acceptance Agent (CAA). A CAA is authorized by the IRS to verify your original documents in person, so you keep your passport in your hand instead of mailing it away.2
- Make an appointment at an IRS Taxpayer Assistance Center. Designated centers can authenticate certain documents in person, by appointment.2
- Mail original or certified copies. If you go this route, request certified copies from the issuing agency where possible, rather than sending true originals.
A passport is the one document that stands alone
For most applicants, a valid passport is the single document that proves both identity and foreign status on its own. Without one, you generally need a combination of two other documents from the IRS's approved list — such as a national ID card, a foreign driver's license, or a birth certificate. A Certifying Acceptance Agent can tell you exactly what will satisfy your situation before anything gets mailed.
When an ITIN expires — and how to renew it
An ITIN is not permanent. If your ITIN is not used on at least one federal tax return for three consecutive years, it expires on December 31 of that third year and must be renewed before you can use it again.3 An expired ITIN doesn't mean you did anything wrong — it just means the number went dormant — but filing with an expired ITIN can delay your refund and cause certain credits to be disallowed until the renewal is processed.
Renewing uses the same Form W-7, marked as a renewal, with the same kind of identity documents. The practical lesson is simple: if you have an ITIN, try to file every year, even in a year you owe nothing, so the number stays active and your record stays clean.
4. Which credits an ITIN can and can't claim in 2026
This is the section that costs families the most money when they get it wrong — and the rules changed recently, so even people who have filed for years should re-read it. The short version: an ITIN lets you file, but several of the biggest credits are tied to having a Social Security number, not just any taxpayer number.
| Credit | Available to ITIN filers? | What the rule actually is |
|---|---|---|
| Earned Income Tax Credit (EITC) | No | The filer, spouse, and any qualifying child must each have a valid SSN. If anyone on the return has an ITIN instead, the EITC is not allowed.5 |
| Child Tax Credit (CTC) | Only for SSN children | The qualifying child must have an SSN. Beginning in 2025, the parent claiming the credit must also have a work-eligible SSN — on a joint return, only one spouse needs one.46 |
| Credit for Other Dependents (ODC) | Yes | A dependent with an ITIN can qualify the family for this $500 nonrefundable credit — the fallback when a child doesn't qualify for the full CTC.4 |
| American Opportunity / education credits | Sometimes | Available to ITIN filers who otherwise qualify, though the refundable portion of the American Opportunity Credit has its own restrictions. |
Two big changes deserve emphasis. First, the Earned Income Tax Credit is completely off-limits to anyone filing with an ITIN: it requires a valid Social Security number for the worker, the spouse, and every child claimed.5 Families sometimes assume that because they work and have children, they qualify — and an incorrect EITC claim can trigger an audit and a multi-year ban.
Second, the Child Tax Credit tightened in 2025. The 2025 tax law set the credit at $2,200 per qualifying child (with the refundable portion capped lower) and — for the first time — required the parent claiming it to have a work-eligible SSN, not only the child. On a joint return, just one spouse needs that SSN, which is exactly the lifeline that makes mixed-status filing work.6
The takeaway isn't “don't bother filing.” It's that the credits you qualify for depend on the exact mix of SSNs and ITINs in your household — and getting that mix mapped correctly is where a real preparer earns their fee, because the difference can be thousands of dollars in either direction.
5. Mixed-status families: filing when one spouse has an SSN
Many South Florida households are mixed status — one spouse has a Social Security number, the other has (or needs) an ITIN, and the children may have a mix of both. The good news is that the tax code is built to handle exactly this, and filing jointly is usually allowed and often advantageous.
Here is how the pieces fit together in practice:
- One spouse with an SSN can unlock the Child Tax Credit. Because the 2025 rule lets a joint return qualify when just one spouse has a work-eligible SSN, a family where one parent has an SSN can still claim the CTC for any child who also has an SSN.6
- An ITIN child gets the $500 credit, not the $2,200 one. If a child has an ITIN rather than an SSN, the family generally can't claim the Child Tax Credit for that child, but may claim the $500 Credit for Other Dependents instead.4
- The EITC is all-or-nothing. If anyone on the return — either spouse — uses an ITIN, the household cannot claim the Earned Income Tax Credit at all.5
“The credits your family qualifies for depend on the exact mix of Social Security numbers and ITINs on the return — map it wrong and you can lose thousands.”
Because the math changes with every combination, mixed-status families benefit the most from sitting down with someone who can model the options — joint vs. separate, which dependents to claim where, and whether applying for an ITIN for a spouse actually improves the outcome. It frequently does, but not always, and the only way to know is to run the numbers.
6. Is it safe to file? Confidentiality and why it matters
The most common reason people don't file is fear — the worry that handing the government your information could be used against you. It's a serious concern and it deserves a straight answer rather than a slogan.
Federal law has long protected the confidentiality of tax-return information, and the IRS's job is to collect taxes, not to enforce immigration law. At the same time, the rules around information sharing between agencies have been the subject of legal and policy disputes, and they can shift. That is precisely why this is a conversation to have with a professional who follows the current landscape — so your decision is based on today's facts, not last year's rumor or a neighbor's anecdote.
Why filing usually helps, not hurts
Filing your taxes and paying what you owe builds a documented record of tax compliance — something that can matter for future immigration applications, mortgage and loan approvals, and simply staying on the right side of the law. A clean filing history is an asset. The goal of a good preparer is to help you file accurately and claim everything you're entitled to, while being candid about the current rules.
The flip side is also true: filing incorrectly — claiming a credit you're not entitled to, using an expired ITIN, or skipping income — creates risk. Accuracy protects you. That is the real argument for getting help rather than guessing.
7. Reporting foreign income and accounts
Many ITIN filers have ties to another country, and that raises a question worth answering carefully: do you have to report income or accounts you have abroad? The answer depends on your tax residency.
If you are a resident alien for tax purposes — typically because you meet the “substantial presence” test for days spent in the U.S. — you are generally taxed on your worldwide income, the same as a citizen. That can include foreign wages, rental income from property abroad, or interest in an overseas account. Nonresident aliens, by contrast, are generally taxed only on their U.S.-source income.
Separately, U.S. taxpayers with foreign bank or financial accounts that exceed certain thresholds may have to file informational reports about those accounts. These rules are technical, the penalties for getting them wrong can be steep, and they are easy to overlook — another reason a family with assets in two countries should have the conversation rather than assume.
One bright spot: no Florida income tax
Florida has no state personal income tax, so an ITIN filer here deals only with the federal return — there is no separate Florida income-tax filing to worry about. That makes South Florida simpler than many states, but it doesn't change the federal rules above.
8. What this means for South Florida families
Taxes don't sit in a box by themselves — they connect to everything else a family is trying to do. The same household that needs an ITIN is often also shopping for life insurance, enrolling in an ACA health plan, or trying to build the financial record that supports a future immigration step. Handling the tax piece correctly makes the rest easier, and getting it wrong can quietly undermine them.
Two things matter especially in our community. The first is language. Filing a federal return you don't fully understand — or worse, handing your documents to someone who can't explain what they're doing — is how mistakes and overpayments happen. JCKC works in English, French, Creole, and Spanish, so you can ask questions and understand the answers in the language you think in.
The second is trust and reach. From Fort Lauderdale and Hollywood to Plantation, Sunrise, and Coral Springs, we work with families who are navigating the U.S. system for the first time and want a preparer who will tell them the truth: what they qualify for, what they don't, and what filing will and won't do for them. Many of our clients have ties abroad, which is exactly where the worldwide-income and foreign-account questions become real.

Need an ITIN, or help filing without an SSN?
We prepare ITIN applications and tax returns for individuals and families — and explain every step in English, French, Creole, or Spanish.
Your ITIN filing checklist
- Confirm you actually need an ITIN — you have a U.S. tax filing or reporting obligation and aren't eligible for an SSN.
- Gather your identity documents — ideally a valid passport, which proves both identity and foreign status on its own.
- Prepare Form W-7 with your tax return, and use a Certifying Acceptance Agent so you don't have to mail your original passport.
- Map your household's SSNs and ITINs to see which credits apply — CTC for SSN children, the $500 Credit for Other Dependents for ITIN dependents, and no EITC if anyone uses an ITIN.
- If you already have an ITIN, check that it hasn't expired — renew it before filing if it's gone unused for three years.
- Ask about foreign income and accounts if you have ties abroad, so nothing required goes unreported.
9. Frequently asked questions
Does getting an ITIN affect my immigration status?
No. An ITIN is a tax-processing number issued for federal tax purposes only. It does not grant or change immigration status, does not authorize you to work, and does not make you eligible for Social Security benefits. It exists so that people who aren't eligible for a Social Security number can still meet their U.S. tax obligations.
Can I get the Child Tax Credit with an ITIN?
The Child Tax Credit requires the qualifying child to have a Social Security number — a child with only an ITIN doesn't qualify for it, though the family may claim the $500 Credit for Other Dependents instead. Beginning in 2025, the parent claiming the credit must also have a work-eligible SSN; on a joint return only one spouse needs one, which is what allows many mixed-status families to claim it.
Can ITIN holders claim the Earned Income Tax Credit?
No. The EITC requires a valid Social Security number for the worker, the spouse if filing jointly, and every child claimed. If anyone on the return is filing with an ITIN, the household cannot claim the EITC. Claiming it incorrectly can lead to an audit and a multi-year ban, so it's important to get this right.
How long does it take to get an ITIN?
Processing times vary, but it commonly takes several weeks from when the IRS receives a complete Form W-7 with the required documents and tax return — and longer during the busy filing season. Using a Certifying Acceptance Agent can make the process smoother because your documents are verified up front, reducing the chance of a rejection that sends you back to the start.
My ITIN is old — is it still valid?
An ITIN expires if it isn't used on a federal tax return for three consecutive years. If yours has gone unused, you'll need to renew it with Form W-7 before filing again. Filing with an expired ITIN can delay your refund and cause some credits to be disallowed until the renewal is processed, so it's worth checking before tax season.
Do I have to mail my real passport to the IRS?
Not necessarily. While the default process asks for original documents, a Certifying Acceptance Agent is authorized to verify your passport in person so you can keep it, and certain IRS Taxpayer Assistance Centers can authenticate documents by appointment. These options let most families apply without sending their only passport through the mail.
