What happens if you don't file taxes while living abroad? Penalties & IRS rules explained
Living outside the US does not remove your obligation to file a US federal tax return. If you are a US citizen or green card holder, the IRS taxes you on worldwide income no matter where you live. Skipping a filing year triggers the same penalty machinery as if you were still stateside, sometimes worse, because FBAR and FATCA add a second layer of exposure.
This guide covers what actually happens after a missed deadline, which penalties apply for 2025 returns filed in 2026, how FBAR and Form 8938 work alongside Form 1040, and the two IRS programs that let non-willful late filers catch up.
What happens if you do not file your taxes
Two penalties start running the day after your due date. The failure-to-file penalty is 5% of unpaid tax per month, capped at 25%. The failure-to-pay penalty is generally 0.5% of unpaid tax per month, up to a maximum of 25%. Interest compounds daily on top of both.
When both penalties apply in the same month, special coordination rules reduce the failure-to-file penalty for that month. Even so, the failure-to-file penalty is ten times heavier than failure-to-pay, which is why filing on time – even without paying – is almost always the right move.
If your return is more than 60 days late and the original due date falls after December 31, 2025, the minimum failure-to-file penalty is the lesser of $525 or 100% of the tax owed, per IRS Topic 653.
The failure-to-pay rate drops to 0.25% per month while an approved installment agreement is in effect, and rises to 1% per month after the IRS issues a final notice of intent to levy and you do not pay within 10 days.
For the full breakdown, see our guide to IRS penalties.
Interest rates are set by the IRS each calendar quarter. The individual underpayment rate was 7% for Q1 2026 and 6% for Q2 2026; later quarters may differ.
TFX example – how a $5,000 balance grows over six months
A US teacher in Vietnam filed her 2024 return in October 2025 owing $5,000, with no extension on file. Six months late, she owed roughly $1,250 in failure-to-file penalty (5% per month, capped at 25%), $150 in failure-to-pay penalty (0.5% × 6 × $5,000), and approximately $175 in interest (illustrative only; the actual amount depends on daily compounding, payment timing, and the quarterly IRS interest rates in effect). Total add-on: about $1,575 on a $5,000 balance, before compounding continues.
If cash flow is the issue rather than filing itself, review the payment plan options before letting a deadline slip.
Know your tax filing duties while abroad
US citizens and green card holders file Form 1040 on worldwide income every year the filing threshold is met, regardless of country of residence.
Many US citizens and resident aliens whose tax home and abode are outside the United States (or who are serving in the military outside the US) qualify for an automatic two-month filing extension to June 15. Any tax owed is still due by April 15, and interest begins accruing after that date.
For the country-by-country breakdown, see our expat tax return guide and the list of foreign country filing deadlines.
People living abroad and not filing taxes often assume that paying host-country tax cancels the US obligation. It does not. The filing requirements generally include a federal income tax return and, if applicable, an FBAR (based on foreign financial account balances) and/or Form 8938 (which has separate thresholds for specified foreign financial assets).
US citizens abroad not filing taxes forfeit the exclusions and credits that would otherwise reduce or eliminate their US tax bill – those benefits only exist on a filed return.
What happens if taxes are not filed by April 15
For 2025 returns, April 15, 2026 is the payment deadline for everyone, regardless of country of residence. Interest starts accruing April 16 on any unpaid balance, even for expats using the automatic June 15 filing window. If you file Form 4868 by April 15, the failure-to-file penalty is suspended through October 15, but the failure-to-pay penalty and interest keep running on any unpaid tax.
What happens if taxes are not filed by October 15
October 15, 2026 is the final extended deadline for 2025 returns. If you timely obtain an extension but still miss the October 15 deadline, the failure-to-file penalty begins after the extended due date. Interest and any applicable failure-to-pay penalty continue running from the original April payment deadline on unpaid tax.
A return filed November 1 with an unpaid balance generally incurs one month of failure-to-file penalty, because any part of a month counts as a full month for IRS penalty purposes, in addition to the failure-to-pay penalty and interest that have been accruing since April.
Filing thresholds for 2025 (returns you file in 2026)
Filing thresholds are gross-income cutoffs, different from standard deductions. For 2025 returns filed in 2026, you generally file if gross income equals or exceeds the amounts set in Publication 501.
Most US expats hit the filing threshold on worldwide income long before they hit any US tax liability, because the FEIE and Foreign Tax Credit are claimed on the return itself. You have to file to use them.
| Filing status | Under 65 | 65 or older |
|---|---|---|
| Single | $15,750 | $17,750 |
| Head of household | $23,625 | $25,625 |
| Married filing jointly (both under 65) | $31,500 | $32,800 (one 65+) / $34,100 (both 65+) |
| Married filing separately | $5 | $5 |
| Qualifying surviving spouse | $31,500 | $32,800 |
The $5 threshold for married filing separately is not a typo. It is a statutory floor that catches almost every MFS filer. Self-employed thresholds are entirely different (see the next section).
For the underlying rules, see our minimum income to file breakdown.
Special filing triggers even below the threshold
Some situations require a return even when gross income is under the standard threshold:
- Net self-employment earnings of $400 or more in the year. This triggers Schedule SE and self-employment tax, regardless of where the work happened. Church employee income of $108.28 or more.
- Household employment taxes, additional Medicare tax, or recapture taxes owed.
- Advance premium tax credit payments received.
- If you are otherwise required to file, you generally must file a return to claim benefits such as the Foreign Earned Income Exclusion or Foreign Tax Credit.
The SE threshold is $400 of net earnings, not "above $400" and not gross revenue. A freelancer with $2,000 in gross receipts and $1,700 in expenses (net $300) is under the trigger. The same freelancer with $1,900 gross and $1,400 in expenses (net $500) has to file.
What counts as income for a US expat
The IRS taxes worldwide income for citizens and residents, and "income" is broader than a paycheck. The categories are set out in Publication 525 and Topic 554:
- Wages, salary, and bonuses paid in any currency, converted to USD at the yearly average rate or the transaction date depending on the item.
- Self-employment and freelance income. Rental income from foreign or US property. Foreign rentals still go on Schedule E.
- Interest, dividends, and capital gains, reported on Schedule B, with Form 1099-INT rules applying to foreign accounts too.
- Pension and Social Security income. Foreign pensions get different treatment depending on the treaty.
- Gambling winnings, cancellation of debt, alimony under pre-2019 agreements, and prize income.
Foreign employer wages are generally taxable and reportable regardless of whether you are paid into a foreign bank account, a US account, or in cryptocurrency. Compensation paid in cryptocurrency is generally included in income at its fair market value when received.
See our guide on earned vs. unearned income.
Have not filed tax returns for years: IRS penalties
The penalty stack multiplies with each missed year. Someone who has not filed tax returns for years faces the failure-to-file penalty and failure-to-pay penalty on every year with a balance, plus daily-compounded interest running from each original due date.
The IRS has no statute of limitations on unfiled returns, so penalties and assessments remain open indefinitely. Once a valid return is filed, the IRS generally has three years to assess additional tax, although longer or unlimited periods can apply in certain situations (including substantial omissions of income or fraud). If no return is filed, the normal assessment limitation period generally does not begin.
For the full penalty math, see our breakdown on penalties for late filers and our guide to back-tax filing for expats.
Have not filed tax returns for 10 years
If you leave returns unfiled for many years – ten years or more is not uncommon among TFX clients – the IRS may prepare a Substitute for Return (SFR) using information reported by third parties. Because SFRs generally do not claim deductions, credits, filing status elections, the Foreign Earned Income Exclusion, or the Foreign Tax Credit, they often result in a higher tax bill.
If the IRS prepared a Substitute for Return, you can generally submit your own original return. If accepted, the IRS will use your filed return to determine the correct tax liability instead of the Substitute for Return.
This is the first step most TFX clients take when catching up. Refunds for tax years where the original filing due date passed more than three years ago are generally forfeited permanently.
IRS penalty summary for late filers (2025 returns)
File the return even if you cannot pay. The 5% failure-to-file penalty is ten times heavier than the 0.5% failure-to-pay penalty.
| Penalty | Rate | Cap |
|---|---|---|
| Failure-to-file | 5% of unpaid tax per month | 25% of unpaid tax |
| Failure-to-file (combined with FTP in same month) | 4.5% per month | 25% |
| Failure-to-file minimum (60+ days late, due after 12/31/2025) | Lesser of $525 or 100% of unpaid tax | – |
| Failure-to-pay | 0.5% per month | 25% of unpaid tax |
| Failure-to-pay (installment agreement) | 0.25% per month | 25% |
| Failure-to-pay (after final levy notice + 10 days) | 1% per month | 25% |
| Interest (individuals, Q1 2026) | 7% per year, compounded daily | No cap |
| Interest (individuals, Q2 2026) | 6% per year, compounded daily | No cap |
NOTE! IRS interest rates are reset each calendar quarter. Later quarters may differ.
What about FBAR and FATCA penalties
FBAR and FATCA sit outside the income tax system. Skipping them creates a separate, larger penalty exposure, often larger than the income tax penalty on the underlying return.
FBAR (FinCEN Form 114) applies if the aggregate value of your foreign financial accounts exceeded $10,000 at any point during the year. It is filed directly with FinCEN, not the IRS. The 2025 FBAR is due April 15, 2026, with an automatic extension to October 15, 2026.
Civil FBAR penalties can be substantial. The amount depends on whether the violation is non-willful or willful, the applicable inflation-adjusted limits, and the facts of the case. Because FBAR penalty rules have been affected by recent court decisions, taxpayers with late or missing FBARs should review the current IRS guidance before relying on a specific penalty amount.
Full details in our FBAR penalties guide.
Form 8938 (FATCA reporting) is filed with Form 1040 when specified foreign asset thresholds are crossed. Failure to file: initial penalty of $10,000, with an additional penalty of up to $50,000 if you do not file after an IRS notice.
See our overview of the FATCA filing requirement and the underlying FATCA statute.
FBAR vs. Form 8938 – which foreign asset form applies
Both forms exist. Many expats file both. They report overlapping but not identical information to different agencies with different thresholds.
FBAR is the account-balance report filed with FinCEN. Form 8938 is the specified-asset report filed with the IRS. A balance in the same account can trigger both.
| Requirement | FBAR (FinCEN 114) | Form 8938 |
|---|---|---|
| Agency | FinCEN | IRS (filed with Form 1040) |
| Reporting threshold (single filer abroad) | $10,000 aggregate at any time in the year | $200,000 on last day OR $300,000 any time |
| Reporting threshold (MFJ abroad) | $10,000 aggregate | $400,000 on last day OR $600,000 any time |
| Covers | Foreign financial accounts | Foreign financial assets (accounts plus other) |
| Non-willful penalty | Substantial; depends on facts and inflation-adjusted limits | $10,000 initial |
| Willful / continued failure | Higher statutory maximums apply; case-specific | Up to $50,000 additional |
| Due date | April 15 (auto to October 15) | With the return |

Getting back on track with streamlined filing procedures
The IRS runs two streamlined programs for non-willful late filers: Streamlined Foreign Offshore Procedures (SFOP) and Streamlined Domestic Offshore Procedures (SDOP). Both require the taxpayer to certify, under penalty of perjury, that the failure to file was non-willful – meaning negligence, misunderstanding, or honest mistake rather than intentional avoidance.
The programs are different, and picking the wrong track is a common (and costly) mistake. The IRS framework is set out in the streamlined filing compliance procedures guidance, and our full streamlined filing walkthrough covers both tracks in detail.
Streamlined Foreign Offshore Procedures
SFOP is the version for taxpayers who meet a non-residency test. For US citizens and green card holders, that generally means being physically outside the US for at least 330 full days in one of the three most recent tax years for which the due date (with extensions) has passed.
SFOP mechanics:
- File the last three years of delinquent or amended returns, with FEIE, FTC, and other benefits claimed on the streamlined returns.
- File the last six years of delinquent FBARs.
- Submit Form 14653 certifying non-willfulness.
- No Title 26 miscellaneous offshore penalty for SFOP-eligible filers.
- For eligible taxpayers whose submission is accepted, the IRS generally does not assert failure-to-file, failure-to-pay, or accuracy-related penalties on the streamlined returns.
Interest on any tax due on the streamlined returns still applies. Our SFOP guide walks through the mechanics, and this English teacher in Korea case study shows the process end-to-end.
Streamlined Domestic Offshore Procedures
SDOP is for taxpayers who do not meet the foreign non-residency test. That is usually people who moved back to the US during the covered years, or dual-status filers.
SDOP mechanics:
- File amended returns for the last three years. SDOP requires previously-filed originals, unlike SFOP.
- File the last six years of delinquent FBARs.
- Submit Form 14654 certifying non-willfulness.
- Pay a 5% miscellaneous offshore penalty on the highest year-end balance of the unreported foreign accounts across the covered period.
That 5% penalty is the key SDOP-vs-SFOP difference. See our SDOP guide for the full process.
What should you do after missing a tax deadline
File the return, then address payment. The failure-to-file penalty stops accruing the day the return is submitted, even if you cannot pay in full. The IRS accepts partial payments, payment plans, and (in some cases) Offers in Compromise.
Our guide on next steps after missing the April deadline covers the practical order of operations.
If you have not filed tax returns for years and want to catch up outside the streamlined programs, our guide on filing back taxes as an expat explains when delinquent return submission is the right path instead.
What happens if my CPA does not file my taxes
The taxpayer, not the preparer, remains liable for penalties. This was settled in United States v. Boyle, 469 U.S. 241 (1985), where the Supreme Court held that reliance on a professional does not constitute reasonable cause for a missed filing deadline.
If your CPA fails to file, you owe the failure-to-file and failure-to-pay penalties. First-time abate relief may apply if your compliance history for the prior three years is clean.
What happens if you ignore IRS notices abroad
The notice sequence generally runs CP14 (balance due) → CP501/503 (reminders) → CP504 (intent to levy state refund) → LT11 or Letter 1058 (final notice of intent to levy and notice of right to hearing). Ignoring the sequence pushes the case into collections.
Our guide on responding to IRS letters covers each stage, and our IRS scam notices guide helps distinguish real notices from fraud.
For expats specifically, three additional exposures exist:
- Passport revocation or denial. Under IRC §7345, the IRS may certify certain seriously delinquent tax debts to the State Department. Following certification, the State Department may deny passport issuance or renewal and may revoke or limit a passport, subject to statutory exceptions. The annually indexed threshold is $66,000 for calendar year 2026.
- Wage and bank levy. The IRS can levy foreign wages paid by US employers and US-source retirement accounts even for taxpayers living abroad.
- Criminal exposure. Tax evasion under 26 U.S.C. §7201 is a felony punishable by up to 5 years in prison and fines up to $250,000 for individuals.
Criminal tax cases are generally reserved for willful violations. Taxpayers whose failure to file was genuinely non-willful typically resolve the matter through the civil tax system, including applicable IRS compliance procedures.
Common tax credits and deductions for expats
Most US expats owe little or no US tax after applying two mechanisms:
- Foreign Earned Income Exclusion. Foreign Earned Income Exclusion. Up to $130,000 of foreign earned income for tax year 2025 (see Rev. Proc. 2025-20), claimed on Form 2555. The exclusion amount is adjusted annually for inflation.
- Foreign Tax Credit. Dollar-for-dollar credit for foreign income tax paid, claimed on Form 1116.
For the choice between the two, see our FTC vs. FEIE comparison.
Additional benefits available on the return:
- Child Tax Credit. Up to $2,200 per qualifying child for tax year 2025, with up to $1,700 potentially refundable through the Additional Child Tax Credit, subject to eligibility requirements.
- Foreign Housing Exclusion or Deduction, stacked on top of FEIE for qualifying housing costs above the base amount.
- Retirement contributions to US IRAs where earned income remains after FEIE. FEIE-excluded income does not count toward IRA contribution limits.
File your taxes from abroad with these easy steps
Filing from outside the US is procedurally identical to filing from within, with two adjustments: form selection expands (Form 2555, Form 1116, FinCEN 114, Form 8938 as needed), and payment mechanics can be more complex if you no longer hold a US bank account. Order of operations:
- Gather worldwide income statements: foreign employer pay stubs, self-employment records, foreign bank interest, brokerage statements, rental income and expenses.
- Convert foreign currency to US dollars using a reasonable published exchange rate that is consistently applied. Depending on the item reported, either an annual average rate or the exchange rate on the transaction date may be appropriate.
- Determine whether FEIE, FTC, or both apply. FEIE requires Form 2555 and a qualifying residency test. FTC uses Form 1116 category-by-category.
- Identify FBAR and Form 8938 obligations based on account balances and aggregate values.
- File Form 1040 with all attached schedules and forms.
- File FinCEN 114 (FBAR) separately with FinCEN by the April 15 / October 15 deadline.
- Pay any balance due by April 15, 2026 to stop interest accrual. Filing extensions do not extend the payment deadline.
Our guide on filing US taxes online and the expat tax form checklist cover the full setup.
Help for US citizens abroad who never filed a tax return
For a US citizen abroad who never filed a tax return, the entry point depends on whether the failure was non-willful and how many years are affected.
Eligible non-willful taxpayers who satisfy the IRS non-residency requirements may qualify for the Streamlined Foreign Offshore Procedures, which generally require submitting the most recent three years of required tax returns and six years of FBARs.
Filers with only one or two recent missed years may not need streamlined at all – a delinquent return submission with a reasonable cause statement can be enough.
Our guide on what to do when you have never filed covers the eligibility triage in detail.
FAQ
The same penalties apply as if you lived in the US: failure-to-file at 5% of unpaid tax per month (capped at 25%), failure-to-pay at 0.5% per month (capped at 25%), and interest compounding daily. FBAR and Form 8938 obligations run in parallel. Refund claims must generally be filed within three years of the original due date (or two years after payment, if later) – after that, refunds are typically forfeited unless a statutory exception applies.
Yes. For eligible non-willful filers who meet the IRS non-residency requirements, the IRS generally does not assert failure-to-file, failure-to-pay, accuracy-related, or FBAR penalties covered by the Streamlined Foreign Offshore Procedures when the submission is accepted. Interest on any tax due still applies. The taxpayer files the most recent three years of required returns, six years of FBARs, and Form 14653 certifying non-willfulness.
There is no statute of limitations on unfiled returns – the normal assessment limitation period does not begin until a valid return is filed. Once filed, the IRS generally has three years to assess additional tax, though longer or unlimited periods can apply in certain situations, including fraud or substantial omissions of income.
No. The June 15 automatic filing extension for qualifying US citizens and resident aliens abroad, and the October 15 extended deadline via Form 4868, both extend filing only. Payment is due April 15, and interest accrues from April 16 on any unpaid balance.
Yes. Under IRC §7345, the IRS may certify seriously delinquent tax debts exceeding the annually indexed threshold ($66,000 for calendar year 2026) to the State Department. The State Department may then deny passport issuance or renewal and may revoke or limit a passport, subject to statutory exceptions. The certification is reversed once the debt is paid, settled, or under a qualifying agreement.
The Supreme Court held in United States v. Boyle (1985) that reliance on a preparer is not reasonable cause. The taxpayer owes the penalties. First-time abate relief may apply if the prior three years are clean.
