Common situations we help accidental Americans with

You were born in the US but have lived abroad your entire life

You were born in the US but have lived abroad your entire life

You hold a US passport and pay taxes where you live – but recently learned the US expects an annual return from you too, regardless of where you live or where your income comes from.

One of your parents is a US citizen – and that may mean you are too

One of your parents is a US citizen – and that may mean you are too

US citizenship can pass through a parent even if you were born and raised entirely outside the US. If you recently discovered this applies to you, the IRS amnesty program may apply.

Your bank or investment platform is pushing for a response

Your bank or investment platform is pushing for a response

A letter arrived asking you to confirm your US person status, provide a Social Security number, or complete a W-9. Some banks have restricted accounts or threatened closure.

You want to renounce – but discovered you need to file first

You want to renounce – but discovered you need to file first

Formally giving up US citizenship requires at least five years of filed US tax returns. If you've never filed, becoming compliant is the required first step before you can proceed.

You have a pension, ISA, or foreign investment account

You have a pension, ISA, or foreign investment account

Your local savings and investment accounts need to be assessed for US reporting obligations. Depending on what you hold – a Stocks and Shares ISA, a pension, foreign ETFs — additional forms may apply.

You've never had a Social Security number and don't know where to start

You've never had a Social Security number and don't know where to start

You were born in the US but left as a child, and have never built any US records. Getting an SSN is the first practical step in the compliance process — and it's something we guide you through.

FAQ about US tax filing for accidental US citizens

1. Am I considered an accidental American if I was born in the US but never lived there?

Yes. Under US law, anyone born on US soil is a US citizen – regardless of whether they later lived there, held a US passport, or identified as American. If you were born in the US, even to non-US parents who returned home shortly after, you likely have US tax filing obligations. The same applies if you were born outside the US to at least one US citizen parent and the citizenship rules at the time of your birth were met.

2. What if I never knew I had to file US taxes?

That's the most common situation we see. If you're an accidental American who has never filed taxes because you simply didn't know you had to, the IRS Streamlined Foreign Offshore Procedure was designed for exactly this – non-willful non-compliance, where you missed filings because you weren't aware of the requirement. Most accidental Americans in this situation qualify, and the program allows you to catch up on three years of federal returns and six years of FBARs without penalties.

3. Do accidental Americans need to file FBARs?

Yes, if the combined value of your foreign bank, pension, or investment accounts exceeded $10,000 at any point during the year. FBAR (Foreign Bank Account Report) is filed separately from your tax return, and penalties for missing it are significant – even when no tax is owed.

4. Why did my foreign bank ask about my US citizenship?

Under FATCA (Foreign Account Tax Compliance Act), foreign banks are required to identify US persons and report their accounts to the IRS. If your bank has flagged a US birthplace or asked for a US Social Security number or W-9, it's a compliance obligation on their side – not a signal that you've done something wrong. Responding with your correct tax status, and getting compliant if you aren't already, is how to resolve it.

5. Do accidental Americans owe US taxes?

The US applies the same income tax rules to accidental Americans as to any citizen, but two tools might help to reduce the bill to zero: the Foreign Tax Credit (which offsets taxes you've already paid to your country of residence) and the Foreign Earned Income Exclusion (which excludes up to $130,000 of foreign earned income for 2025).

6. How many years of US tax returns may I need to file?

Under the Streamlined Foreign Offshore Procedure, the filing window is the last three years of federal tax returns and six years of FBARs – regardless of how long you've been non-compliant.

7. What documents do accidental Americans need to get started?

Typically: records of your income for the three filing years, details of any non-US bank, pension, or investment accounts, and your passport or birth certificate for citizenship verification. If you don't have a Social Security number, we'll guide you through the process of obtaining one.

8. Can TFX help accidental Americans with late tax filings?

Yes – accidental American filing help is a core part of what we do. We determine the correct path for your situation, prepare your returns and required reporting, and handle the Streamlined submission end-to-end.

9. I want to renounce my US citizenship – where do I start?

Renunciation requires at least five years of filed US tax returns before the consulate appointment, plus a final-year return and IRS Form 8854 after. If you've never filed, the Streamlined Procedure is the first step – it covers three years, after which you can file the remaining years to meet the five-year requirement.
