Moving to the US comes with a mountain of paperwork, and taxes are one of the most confusing parts. If you arrived on a spouse visa and don’t have a Social Security Number (SSN) yet, you might be wondering: Do I even need to file taxes? And how can I, without an SSN?
The short answer: yes, many new immigrants still need to file, and the IRS has a system designed exactly for people in your situation. It’s called an ITIN – an Individual Taxpayer Identification Number.
Our family was lucky in one way: we applied for green cards before we even moved, so we all had our Social Security Numbers from day one. But honestly? That didn’t make taxes any less confusing. Our first year, my father was the sole earner, and we just handed the accountant whatever documents he asked for. I couldn’t have told you what we actually filed. If that’s where you are right now – SSN or not – this guide is for you. Let’s walk through it together.
What Is an ITIN, and Do You Need One?
An ITIN is a 9-digit tax ID the IRS issues to people who must file taxes but can’t get an SSN. It looks like an SSN but starts with 9, and it’s for tax purposes only – not work authorization or benefits.
You likely need an ITIN if:
- You moved to the US on a spouse visa (such as a K-1 or CR-1/IR-1) and are not yet eligible for an SSN.
- You need to file a joint tax return with your spouse.
- You want to claim tax credits or benefits you’re entitled to.
We never needed an ITIN – our green cards were approved before we arrived. But many spouse-visa families wait months for SSNs, and taxes don’t wait for paperwork. If that’s you, the ITIN is your starting line.
ITIN vs. SSN: What’s the Difference?
- Issued by: ITIN – IRS; SSN – Social Security Administration
- Used for: ITIN – filing taxes only; SSN – taxes, work, benefits
- Format: ITIN – 9XX-XX-XXXX; SSN – XXX-XX-XXXX
Don’t worry if the distinction feels confusing. The main point: an ITIN lets you file taxes legally while you wait for SSN eligibility.
Step-by-Step: Getting an ITIN and Filing Your First Return
Step 1: Check Whether You Need to File
You must file if your income exceeds the IRS threshold for your filing status (higher for married filing jointly). Even if you’re not required to, consider filing anyway – you might be owed a refund or need it to claim credits.
Step 2: Apply for an ITIN with Form W-7
Apply with IRS Form W-7. You’ll need:
- A valid passport (simplest proof of identity and foreign status), or two other approved documents.
- Your completed federal tax return (the W-7 is usually submitted together with it).
Mail it to the IRS ITIN Operation office, or visit an IRS-authorized Certifying Acceptance Agent to verify documents in person.
Realistic timeline: ITIN processing typically takes 6-11 weeks (longer during tax season). Apply early – ideally in January or February – so you’re not rushing before the April filing deadline.
Here’s the part nobody tells newcomers: even with SSNs in hand, our first filing was a black box. The accountant asked for documents, my father handed them over, and that was it. Almost nothing is written that explains this process step by step for new immigrant families – so you end up depending entirely on the professional, without understanding your own return. That’s the gap this blog is trying to fill.
Step 3: File Your Tax Return
Once you have your ITIN, file your federal return (Form 1040) like anyone else. A few things to know:
- Filing status: Married filing jointly usually means lower taxes than filing separately – but run the numbers or ask a professional.
- Your spouse’s return: Your spouse can include you on a joint return using your ITIN.
- State taxes: Most states with an income tax accept ITINs too – check your state’s rules.
Step 4: Keep Good Records
Save copies of everything: your W-7, passport copies, filed returns, and IRS letters. You’ll need them if questions come up – and when you get an SSN, notify the IRS to link your records.
Why It Pays to Understand Your Own Return
A family we know learned this the hard way. The husband had arrived from Korea not long before filing, then got an IRS letter: about $10,000 unpaid, penalties adding up monthly. He’d done everything right – paid the balance on the last page of his Form 1040. From what I heard, the IRS eventually admitted the error was theirs; his payments hadn’t been credited. But months of stress came first.
I’m sharing this because it’s why every new immigrant family should understand the basics of their own return, even with a professional preparing it.
Common Questions from New Immigrants
“Will filing taxes with an ITIN affect my immigration status?”
Filing is a legal obligation and generally viewed positively – it shows you’re following US law. Keep copies; they can serve as useful documentation.
“What if I had no income this year?”
With no income and no filing requirement, you generally don’t need to. But a joint return with your spouse requires an ITIN for you.
“Do I owe taxes on money I earned before moving?”
Generally, US tax obligations begin when you become a US tax resident (based on visa type and days present). Rules vary, so ask a tax professional about your situation.
Looking back, our filings always worked out – the accountants did their job. But we never understood what was happening with our own money, and that bothered me enough that I’m writing the guide I wish someone had handed us. You don’t need to become a tax expert – just understand enough that the process isn’t a black box.
A Simple First-Year Checklist
- Determine whether you need to file (check IRS filing thresholds)
- Gather identity documents (passport is simplest)
- Complete Form W-7 and your tax return together
- Submit early (January-February) to allow 6-11 weeks of processing
- Save copies of everything you file
- When you get an SSN later, notify the IRS to link your records
You’ve Got This
Taxes feel scarier than they are. Millions of immigrants file with ITINs every year – the system was built for this. Take it one step at a time, start early, and don’t hesitate to get help – from a tax professional or a free program like VITA (Volunteer Income Tax Assistance), which serves many immigrant communities.
