Unfiled Returns & Expats

Expat Hasn't Filed US Taxes: What to Do Now (2026 Guide)

By Angeline Balsitis, EA · Reviewed by Melissa Ly, Chief Tax Officer · Published July 14, 2025 · Updated July 7, 2026 · Editorial Standards

Maybe your bank in Lisbon or Toronto asked whether you're a "US person." Maybe a passport renewal appointment mentioned tax compliance, or a friend abroad just told you Americans have to file no matter where they live — and your stomach dropped, because you haven't filed in years. Take a breath: the IRS built a specific, penalty-free door for exactly your situation, and most expats who use it owe far less than they fear. This guide shows you the door and how to walk through it before it closes.

The centerpiece is a signed certification — Form 14653 — where you explain, in your own words, why you didn't file. The image below shows you exactly what the streamlined package looks like and where the pieces fit, so keep reading before you draft anything.

Why you still owe US filings — even after years abroad

The United States taxes its citizens and green-card holders on worldwide income, no matter where they live. That's citizenship-based taxation, and almost no other country does it — which is why so many honest people abroad genuinely never knew they had to file. Paying full tax in your country of residence does not replace a US return.

Here's the part that surprises people in the other direction: most expats who catch up owe little or no US tax. The foreign earned income exclusion (Form 2555) shelters over $130,000 of foreign wages in recent years, and the foreign tax credit (Form 1116) offsets US tax dollar-for-dollar with tax you already paid abroad. But both are claimed on a return — skip the return and you get neither.

Two separate obligations ride alongside the tax return. The FBAR (FinCEN Form 114) reports foreign accounts whenever their combined balances top $10,000 at any point in the year — even if you owe zero tax. Form 8938 does similar reporting to the IRS itself at higher thresholds. Missing these carries its own penalties, entirely apart from the tax. For the broader landscape of catching up from overseas, see our guide to expat back taxes.

Do you actually have a filing requirement? Check before you panic

Not every American abroad has to file — the requirement kicks in only when gross income crosses the filing threshold, which is roughly the standard deduction for your filing status. If you're retired and Social Security is your only income, it's usually not taxable and you may have no unfiled-return problem at all.

The picture changes fast once other income appears. IRA and 401(k) withdrawals, a US or foreign pension, rental income, dividends, or self-employment income all count toward the threshold — and they can also make up to 85% of your Social Security taxable. Run each year separately: some years you may have had no requirement, others you did.

One caution: the FBAR has no income test. A retiree who owes zero tax but kept €40,000 in a foreign checking and savings account still owed an FBAR every year. If tax returns aren't your problem but FBARs are, note that the IRS removed the Delinquent FBAR Submission Procedures on June 30, 2026 — but late FBARs can still be e-filed through FinCEN with an explanation, and penalties are not automatic when the account income was reported and taxed, though there is no longer a guaranteed penalty-free program.

If your unfiled years stretch back a decade or more, don't assume you must reconstruct all of them. The whole point of streamlined is that you won't — but for context on how the IRS treats long-gap non-filers generally, see haven't filed taxes in 10 years.

What happens if an expat never files US taxes

Living overseas doesn't hide you from the IRS — under FATCA, banks in over 100 countries report US-person accounts directly to it. If you keep not filing, the sequence runs like this, in order:

1. Your bank reports you. FATCA data flows to the IRS showing accounts under your Social Security number with no matching returns. This is the trigger, and it's automated.
2. Delinquency notices go out — CP59, then LT26 — often to your last known US address. Escalation continues whether or not you ever see them.
3. The IRS files for you. A Substitute for Return uses only what payers reported: single status, no foreign tax credit, no exclusion, no deductions — the worst possible math. Read what that means in the IRS filed a substitute return for me.
4. The inflated balance is assessed and collection notices begin, with failure-to-file penalties of 5% per month (up to 25%) already baked in, plus interest.
5. Your passport is at risk. Once the assessed debt reaches $66,000 (the 2026 threshold), the IRS can certify it to the State Department, which can deny renewal or revoke the passport — the one document an expat cannot live without. Details: passport revoked for tax debt.
6. US-source income gets levied. The IRS can't easily reach a foreign bank account, but it doesn't need to: it can levy US bank and brokerage accounts, US pensions — and take up to 15% of Social Security through the Federal Payment Levy Program. See can the IRS garnish Social Security.

And at any point in that sequence, the moment an examination opens, the penalty-free streamlined path is gone. That's the real cost of waiting — not a specific date, but a door that closes without warning.

Your options for catching up: which path fits

There are four legitimate ways back to compliance, and choosing the wrong one is expensive. The table compares them; the paragraphs after it explain the fit.

For most expats reading this page, the streamlined offshore procedures are the answer: three returns, six FBARs, zero penalties. If you've already moved back stateside and can't meet the 330-day test, streamlined domestic offshore is the cousin program — same idea, but with a 5% penalty on certain assets, which is why timing a submission before a move home can matter.

What you should not do is quietly mail in old returns outside any program, or start filing current years while ignoring the past. That's a quiet disclosure — it waives nothing, protects nothing, and can draw attention to exactly the history you're trying to fix.

If catching up produces a balance you can't pay at once, the ordinary IRS toolkit applies from abroad too — payment plans, hardship status, and in genuine cases an offer in compromise. Our hub on how to settle tax debt yourself covers those options in depth so this page can stay focused on the expat-specific path.

What catching up actually costs: a worked example at $11,300

Numbers make this concrete, so here's a clearly hypothetical scenario. Say you're 68, retired in Portugal, and haven't filed since you left the US nine years ago. Your income: about $25,200 a year in Social Security, $18,000 in traditional IRA withdrawals with no withholding, and a small foreign pension. Under streamlined you file only the last three years, and suppose the tax works out to roughly $3,766 per year — $11,300 total across the three returns.

Now compare the two roads:

• Without streamlined: the failure-to-file penalty runs 5% per month up to 25% of the unpaid tax — about $2,825 on $11,300. The failure-to-pay penalty (0.5% per month) stacks on top of that, month after month. And if your Portuguese accounts ever topped $10,000 combined, non-willful FBAR penalties could add five figures more, per our guide to the FBAR penalty. You can estimate your own penalty exposure with our IRS Penalty & Interest Calculator.
• With streamlined: every one of those penalties is waived. You owe the $11,300 plus interest — and nothing else.

Can't write an $11,300 check from a fixed income? A long-term IRS installment agreement (available online for balances up to $50,000) spreads it over up to 72 months — roughly $157 a month before interest ($11,300 ÷ 72), while interest continues to accrue until it's paid. And note what streamlined doesn't change: if any of those three years shows a refund instead of a balance — say, from foreign tax credits — you can still claim it, but only within the three-year refund window.

Expat filing deadlines and the rights you lose when they pass

Expats get more time to file than stateside taxpayers, but every clock in this table is real — and two of them quietly take money or options away.

How to catch up on unfiled US taxes from abroad, step by step

The streamlined submission is a defined package, not an open-ended negotiation — done in this order, it's a project you can finish in weeks.

1. Confirm which years you had a filing requirement. Compare your gross worldwide income — Social Security, pensions, IRA withdrawals, wages, rentals, investments — to the US filing threshold for each year, which is roughly the standard deduction for your filing status.
2. Pull your IRS records. Request wage and income transcripts to see what US payers — the Social Security Administration, IRA custodians, brokerages — already reported under your Social Security number, so your returns match the IRS's file.
3. Test your streamlined eligibility. You need non-willful conduct and the non-residency test: in at least one of the last three years, no US abode and at least 330 full days physically outside the United States. The IRS must not have contacted you first.
4. Prepare the package. Three years of Form 1040 with all required international forms, six years of FBARs (FinCEN Form 114), and the Form 14653 certification explaining in writing why your failure to file was non-willful.
5. Submit and settle the balance. File the streamlined package with tax and interest paid, or arrange an IRS payment plan if you can't pay in full — interest continues until the balance is paid.
6. Stay compliant going forward. File every year by the automatic June 15 expat deadline (pay by April 15 to avoid interest) and e-file your FBAR annually if foreign accounts exceed $10,000 combined.

The step that decides everything is the Form 14653 narrative. It's a signed statement under penalty of perjury — vague or careless wording can undercut the whole submission, while an honest, specific account of why you didn't know is exactly what the program was built for.

When you can handle this yourself — and when help changes the outcome

Plenty of expat catch-up cases are genuinely DIY. You can likely handle this alone if Social Security was your only income and no filing was required; if your only gap is missing FBARs on fully-reported income; or if your three streamlined years are simple returns — one pension, one bank account, foreign tax credits that zero out the bill — and you're comfortable writing the Form 14653 statement yourself.

Experienced help changes the outcome when the facts get heavier: anything that could look willful (large accounts, income routed to avoid US reporting, advice you ignored), foreign pensions or investment funds with tricky US treatment, self-employment income abroad, a balance you can't pay, a debt approaching the $66,000 passport threshold — or any letter already received from the IRS, since contact can end streamlined eligibility and the response strategy shifts completely. The willfulness call in particular is one to get right the first time; there's no do-over on a signed certification. If your gap is shorter and mostly stateside, our guide to haven't filed taxes in 5 years walks the domestic version of this decision.

Terms on the streamlined checklist, decoded

• FBAR (FinCEN Form 114): an annual electronic report of foreign accounts, required whenever their combined balances exceed $10,000 at any point in the year — separate from your tax return.
• FATCA: the law that makes foreign banks report US-person accounts to the IRS — the reason your bank asked if you're a "US person," and the reason non-filers abroad get found.
• Form 14653: the signed certification at the heart of a streamlined foreign submission, where you attest that your failure to file was non-willful and explain why.
• Non-willful: conduct due to negligence, mistake, or a good-faith misunderstanding of the law — the eligibility line between streamlined and the much harsher voluntary disclosure route.
• Substitute for Return (SFR): a return the IRS files for you using only payer data — no credits, no exclusions, no deductions — producing the largest possible balance.
• Foreign earned income exclusion (FEIE): the Form 2555 election that shelters over $130,000 of foreign wages or self-employment earnings from US tax — but only on a filed return.
