Yes, if you are a foreign national or resident alien planning to leave the United States, you almost always need to file IRS Form 1040-C before you board your flight. This form is the U.S. Departing Alien Income Tax Return, and it reports income earned (or expected to be earned) during the year up to the date you leave the country.
Failing to file Form 1040-C, or its lighter cousin Form 2063, can trigger serious consequences. The IRS can refuse to issue your sailing permit (also called a departure permit), and under IRC §6851, it can even assess your tax immediately and demand payment on the spot. According to the IRS, more than 44 million nonresident and dual-status filings are processed each year, yet a large share of departing aliens never realize the sailing permit rule exists until customs or a tax professional flags it.

Who Must File Form 1040-C and Why It Exists
Form 1040-C exists because the IRS wants to collect tax before a foreign national leaves U.S. soil and becomes harder to track. The legal authority comes from IRC §6851(d), which directs departing aliens to obtain a certificate of compliance, commonly called a sailing permit, from the IRS before leaving the country. Without that permit, your departure can be flagged, and the IRS can pursue jeopardy assessment — an immediate demand for full payment of estimated tax due.
The plain-English meaning is simple. If you are not a U.S. citizen and you plan to leave, the government wants proof that you have settled, or arranged to settle, your federal income tax bill for the year. The consequence of ignoring the rule is that the IRS can collect tax owed at the airport, withhold property, or issue a levy under IRC §6331. A common misconception is that filing your normal Form 1040 or Form 1040-NR at year-end is enough — it is not, because Form 1040-C is filed before departure and the regular return is filed after the tax year ends.
Resident Aliens Leaving the United States
A resident alien is anyone who passes the substantial presence test or holds a green card. If you are a resident alien and you plan to leave the U.S., either temporarily or permanently, you must usually obtain a sailing permit. The IRS uses Form 1040-C to compute your tax for the part of the year you were present, plus any income you reasonably expect to earn before you depart.
The consequence of skipping this step is that you are technically not allowed to leave with the IRS’s blessing, and any tax found owing later can be collected with penalties under IRC §6651. For example, Priya, an H-1B software engineer in Seattle, accepts a transfer to her employer’s Bangalore office in August. She must file Form 1040-C reporting her January–August wages and any year-end bonus she will receive before she boards her flight.
Nonresident Aliens with U.S.-Source Income
A nonresident alien who earned U.S.-source wages, scholarships, or business income during the year usually must also file Form 1040-C before leaving. The form computes tax only on income that is effectively connected with a U.S. trade or business or that is U.S.-source under IRC §871. Treaty exemptions, such as those in the U.S.–India tax treaty or U.S.–U.K. tax treaty, can reduce or eliminate certain items, but you still must file the form.
The consequence of ignoring this duty is the same: no sailing permit and possible jeopardy assessment. A common misconception is that students on F-1 or J-1 visas are exempt — they are not, although many qualify to file Form 2063 instead because they have no taxable income beyond treaty-exempt scholarships.
Who Can File the Shorter Form 2063 Instead
Some departing aliens qualify for the short Form 2063, which is a one-page statement rather than a full tax return. You may use Form 2063 if you are a resident alien who has filed all prior-year returns and paid all tax due, or a nonresident alien with no taxable U.S. income for the current year and the prior year. Diplomats, certain employees of foreign governments, students with only treaty-exempt income, and exchange visitors with no taxable income often qualify.
The consequence of using the wrong form is rejection by the IRS field office and a delayed sailing permit. For example, Diego, a Mexican F-1 student with only a tax-treaty-exempt scholarship and no on-campus wages, may file Form 2063. But if Diego also worked under Curricular Practical Training and earned wages, he must file Form 1040-C instead.
Aliens Who Do Not Need to File Either Form
A few categories skip the sailing permit entirely. These include foreign diplomats and their staff with A or G visas, employees of international organizations, students and exchange visitors on F, J, M, or Q visas with no U.S.-source income other than allowances, and certain alien residents of Canada or Mexico who commute to work in the U.S.
The consequence of wrongly assuming you fall into one of these buckets is a denied permit and a missed flight. A common misconception is that any student is exempt — only students with no taxable U.S. income beyond exempt allowances and treaty amounts are truly off the hook.
When and Where to File Form 1040-C
Form 1040-C must be filed at least two weeks before you plan to leave the United States, but no earlier than 30 days before departure. You file it in person at an IRS Taxpayer Assistance Center, not by mail and not electronically. Bringing your passport, visa, I-94 record, all W-2 and 1099 forms, prior-year tax returns, and proof of estimated tax payments is required.
The consequence of filing too late is that the IRS will not issue your sailing permit before your flight, and you may have to reschedule travel. The consequence of filing too early is that the IRS cannot accept the form because the 30-day window has not opened. A common misconception is that you can mail the form — you cannot, because the sailing permit must be issued in person after an interview with an IRS agent.
Documents to Bring to the IRS Office
Bring your passport with all visa stamps, your most recent Form I-94 arrival/departure record, all wage statements and self-employment records, bank interest statements, brokerage Forms 1099, prior-year federal returns, and proof of estimated tax payments such as Form 1040-ES vouchers. If you have dependents, bring their Social Security numbers or ITINs.
The consequence of arriving without complete documentation is a same-day denial. For example, Mehmet, a Turkish L-1 manager leaving in November, brings his W-2 stubs but forgets his I-94 print-out. The IRS officer cannot confirm his entry date and refuses to issue the sailing permit until he returns with the missing record.
Filing Two Forms 1040-C in the Same Year
If you leave the country, return, and leave again in the same calendar year, you must file Form 1040-C each time you depart. The IRS uses each filing to update your year-to-date income and reconcile the prior sailing permit. The consequence of skipping the second filing is the same as skipping the first — no permit and possible jeopardy assessment.
A common misconception is that one sailing permit covers the whole calendar year. It does not, because the permit is tied to the departure event, not the tax year. Filing the second Form 1040-C also lets you claim credit for tax already paid with the first one on Line 36 of the second filing.
Line-by-Line Walkthrough of Form 1040-C
Form 1040-C is structured similarly to Form 1040 but compresses a partial-year picture onto one return. The form has an identifying section, three income groups, deductions and exemptions, a tax computation, and a payments and balance-due section. Following the Form 1040-C instructions line by line is essential, because the IRS officer will check each entry against your supporting documents.
The consequence of leaving lines blank or estimating without documentation is rejection and re-filing. A common misconception is that you can guess at year-end totals — the IRS expects reasonable, documented projections, not blind estimates.
Identification Section and Filing Status
The top of the form asks for your name, U.S. taxpayer identification number (SSN or ITIN), passport number, country issuing the passport, U.S. visa type, date of entry, expected date of departure, and your home address abroad. You must check one of three filing-status boxes: resident alien, nonresident alien, or dual-status alien.
The consequence of choosing the wrong status is that the entire tax computation will be wrong, because resident aliens are taxed on worldwide income while nonresident aliens are taxed only on U.S.-source income under IRC §872. For example, Yuki, a Japanese resident alien who passed the substantial presence test in May, must check resident alien and report worldwide income, including her Tokyo rental property.
Group I — Income Subject to Graduated Tax
Group I covers wages, salaries, tips, business income, capital gains, and other income taxed at the regular graduated rates of IRC §1. Resident aliens report all such income, while nonresident aliens report only income effectively connected with a U.S. trade or business.
The consequence of misclassifying income — for example, putting nonresident dividend income in Group I instead of Group II — is overpayment or underpayment of tax. A common misconception is that scholarship income always belongs here. It does not, because nondegree scholarships to nonresidents are typically taxed at a flat 30% in Group II under IRC §871(a).
Group II — Income Not Effectively Connected (Flat 30%)
Group II is reserved for nonresident aliens. It captures U.S.-source income that is not effectively connected with a U.S. trade or business, such as dividends, certain interest, royalties, and certain gambling winnings. Tax is generally a flat 30% under IRC §871(a), reduced by treaty if applicable.
The consequence of forgetting Group II is missing real tax liability. For example, Hans, a German national on a B-1 business visa, earns $10,000 in U.S. dividends during a six-month stay. He reports the dividends in Group II at 15% under the U.S.–Germany tax treaty, not at the default 30%.
Group III — Income Exempt from U.S. Tax
Group III lists income that is exempt under a tax treaty, the Internal Revenue Code, or another legal authority. Examples include treaty-exempt scholarships, treaty-exempt teacher pay, and certain foreign-source income earned by nonresidents. You must identify the treaty article and country.
The consequence of failing to disclose treaty-exempt income in Group III is that the IRS may treat it as taxable. A common misconception is that exempt income does not need to be listed at all — it does, because Form 1040-C requires full disclosure even when no tax is due.
Deductions, Exemptions, and Tax Computation
Form 1040-C lets you claim itemized deductions if you qualify, plus the standard deduction only if you are a resident alien (nonresident aliens generally cannot claim it, except for students from India under the treaty). The Tax Cuts and Jobs Act suspended personal exemptions through 2025, but for tax years after that suspension, you would claim them on the exemptions line.
Tax is computed using the tax tables or tax rate schedules in the Form 1040-C instructions. The consequence of using the wrong rate schedule (for example, single instead of married filing separately, which is required for most nonresidents) is an inaccurate liability and possible IRS rejection.
Payments, Credits, and Balance Due
The payments section captures federal income tax withheld from W-2s and 1099s, estimated tax payments made during the year, prior Form 1040-C payments, and refundable credits such as the Additional Child Tax Credit where eligible. Subtracting payments from tax gives either a balance due, which generally must be paid before the IRS issues the sailing permit, or a credit carried to your year-end Form 1040 or 1040-NR.
The consequence of underpaying is a refused permit. A common misconception is that you can post-date a check or promise to pay later — you cannot, except where you qualify to file Form 1040-C without paying the tax (see the next section).
Filing Form 1040-C Without Paying the Tax
In limited situations, the IRS will accept Form 1040-C and issue a sailing permit even if you do not pay the tax shown due. To qualify, you must convince the IRS that your departure does not jeopardize collection — for example, you have substantial U.S. assets, you intend to return, or your employer guarantees payment. The IRS may require a bond under IRC §6851(e).
The consequence of trying this without proper documentation is denial. For example, Carla, an Argentine consultant returning home for three months but keeping her New York apartment and brokerage account, can show enough U.S. assets to convince the IRS she will pay her year-end Form 1040 liability. She files Form 1040-C, gets her sailing permit, and pays the actual tax in April with her Form 1040.
How Form 1040-C Interacts with Other Tax Forms
Form 1040-C is not a substitute for your annual return. After year-end, you still must file Form 1040 (if a resident alien), Form 1040-NR (if a nonresident alien), or both as a dual-status filer. Tax paid with Form 1040-C is treated as a credit on the year-end return.
The consequence of skipping the year-end return is normal late-filing penalties under IRC §6651 plus interest under IRC §6601. A common misconception is that the sailing permit closes the tax year — it does not, because Form 1040-C is only a prepayment mechanism, not a final return.
Dual-Status Filers and the Residency Termination Date
A dual-status alien is someone who is a resident for part of the year and a nonresident for the other part. The residency termination date is generally the last day of physical presence, provided you establish a closer connection to a foreign country and are not a U.S. resident at any time during the next calendar year. Dual-status filers must file both a dual-status return and statement at year-end.
The consequence of misidentifying the termination date is that the IRS could treat you as a full-year resident, taxing worldwide income for months you were already abroad. For example, Amir, an Iranian engineer who leaves on July 15, must establish that he had a tax home in Iran from July 16 onward and did not return to the U.S. that year.
Expatriation, Form 8854, and the §877A Exit Tax
If you are a long-term green card holder (lawful permanent resident in 8 of the last 15 years) who is abandoning your green card, or a U.S. citizen who is renouncing citizenship, you may also be a covered expatriate subject to the §877A mark-to-market exit tax. You must file Form 8854 the year of expatriation and certify five years of tax compliance.
The consequence of failing to file Form 8854 is a $10,000 penalty and continued treatment as a U.S. taxpayer until you do. A common misconception is that Form 1040-C alone handles expatriation — it does not, because the exit tax is computed on Form 8854 and reported on the final Form 1040 or 1040-NR.
Three Common Departure Scenarios
Below are three of the most common departing-alien scenarios, with the action a taxpayer takes and the direct consequence under federal law.
H-1B Worker Permanently Relocating
| Filing Action | Tax Consequence |
|---|---|
| File Form 1040-C 2 weeks before flight | Sailing permit issued; tax prepaid on year-to-date wages |
| Skip Form 1040-C and board flight | Possible jeopardy assessment under IRC §6851 |
| File Form 2063 instead of 1040-C | Rejected because H-1B worker has taxable wages |
| File year-end Form 1040 from abroad | Required even after Form 1040-C; tax credited |
Nonresident Investor Leaving Mid-Year
| Filing Action | Tax Consequence |
|---|---|
| Report Group II dividends with treaty rate | Flat tax reduced from 30% to treaty rate |
| Omit Group II income | Underpayment, interest, and possible permit denial |
| Claim standard deduction as nonresident | Disallowed unless Indian student treaty applies |
| File year-end Form 1040-NR | Required to reconcile final liability |
Long-Term Green Card Holder Abandoning Status
| Filing Action | Tax Consequence |
|---|---|
| File Form 1040-C before flight | Sailing permit issued for departure |
| File Form 8854 with year-end return | Exit tax computed on unrealized gains |
| Skip Form 8854 certification | $10,000 penalty plus continued U.S. tax status |
| File final dual-status Form 1040 | Closes residency period properly |
Mistakes to Avoid When Filing Form 1040-C
Avoiding the most common errors will save you days of back-and-forth with the IRS and possibly your flight. Each mistake below has triggered real denials at IRS Taxpayer Assistance Centers.
- Filing by mail or online — Form 1040-C must be filed in person at a Taxpayer Assistance Center, and a mailed form will not produce a sailing permit.
- Filing more than 30 days before departure — the IRS office will reject the form because the window has not opened.
- Filing fewer than 14 days before departure — the IRS may not have time to process it before your flight.
- Choosing the wrong filing status — checking resident alien when you are dual-status causes worldwide-income overreporting.
- Forgetting Group II income — leaving off dividends, interest, or royalties causes underpayment and possible permit denial.
- Skipping treaty disclosure on Group III — exempt income still must be listed and the treaty article cited.
- Claiming the standard deduction as a nonresident — disallowed except for Indian-treaty students.
- Not bringing your passport, visa, and I-94 — the IRS officer cannot verify identity or entry date.
- Forgetting prior estimated tax payments — you will appear to owe more than you do.
- Assuming Form 1040-C ends your tax year — it does not, and a year-end Form 1040 or 1040-NR is still required.
Do’s and Don’ts of Form 1040-C
The list below highlights the most important practices, with a short why attached to each.
- Do schedule your IRS appointment early, because Taxpayer Assistance Centers are appointment-only and book up.
- Do bring originals of every supporting document, because the officer will not accept photocopies for identity verification.
- Do project year-end income honestly, because deliberate underestimation can trigger fraud penalties under IRC §6663.
- Do claim every applicable treaty benefit, because failing to claim is the single biggest cause of overpayment for nonresidents.
-
Do keep your stamped sailing permit, because U.S. Customs and Border Protection may ask for it on departure.
-
Don’t assume you are exempt without checking Publication 519, because the exemption rules are narrow.
- Don’t forget Form 8854 if you are expatriating, because the §877A exit tax applies separately.
- Don’t pay tax with a foreign check, because the IRS office accepts only U.S.-drawn checks, money orders, or IRS Direct Pay.
- Don’t rely on your employer’s payroll department for tax advice, because Form 1040-C is the taxpayer’s personal responsibility.
- Don’t leave the country without the permit, because re-entry and future visa applications can be affected.
Pros and Cons of Filing Form 1040-C
Filing Form 1040-C has real benefits and real burdens. Weighing them helps you plan your departure better.
- Pro: Issues a sailing permit that prevents customs holds, because IRC §6851 authorizes the permit.
- Pro: Locks in treaty benefits early, because Group III disclosure documents your treaty position.
- Pro: Lets you prepay tax and avoid year-end balance-due penalties, because payments count as estimated tax.
- Pro: Provides a paper trail for future U.S. visa applications, because consular officers sometimes ask for past compliance.
-
Pro: Identifies dual-status issues early, because the form forces you to consider your residency termination date.
-
Con: Requires an in-person IRS visit, because remote filing is not allowed.
- Con: Demands payment up front in most cases, because deferred payment requires bond or strong U.S. assets.
- Con: Adds a second filing on top of your year-end Form 1040 or 1040-NR, because Form 1040-C is not a final return.
- Con: Uses estimated full-year income, because you must project income that has not yet occurred.
- Con: Carries significant penalties for inaccuracy, because IRC §6662 applies to substantial understatements.
State Tax Considerations on Departure
Federal Form 1040-C does not cover state tax, but states such as California, New York, and New Jersey have their own residency rules that can keep you on the hook even after you leave the U.S. California’s Franchise Tax Board uses the closest connection test, while New York applies a statutory residency test of 183 days plus a permanent place of abode.
The consequence of ignoring state rules is a state assessment after you leave, often years later, with interest. For example, Linh, a Vietnamese national working in San Francisco for three years, leaves in October. She must file a part-year California return because her California domicile ended that day, even though Form 1040-C handled the federal side.
Court Rulings That Shape Form 1040-C Practice
Several cases shape how the IRS administers the sailing permit rule. In Park v. Commissioner, 25 F.3d 1289 (5th Cir. 1994), the court reinforced that gambling winnings of a nonresident are subject to the flat 30% Group II tax and cannot be netted against losses. In Topsnik v. Commissioner, 146 T.C. 1 (2016), the Tax Court held that a long-term green card holder who failed to formally abandon his status remained a U.S. resident even after moving abroad, triggering full worldwide taxation.
The consequence of ignoring these precedents is real tax exposure. A common misconception is that physically leaving the country ends your tax obligations — it does not, because formal status changes (green card abandonment via Form I-407, citizenship renunciation, residency termination statement) are required.
FAQs
Do I really need to file Form 1040-C if I am only leaving for a short trip?
No. Short personal trips by resident aliens who intend to return generally do not require Form 1040-C, but you should still confirm with Publication 519 before traveling.
Can I file Form 1040-C electronically?
No. Form 1040-C is filed in person at a Taxpayer Assistance Center because the IRS issues the sailing permit only after an in-person review.
Is Form 1040-C my final tax return for the year?
No. You must still file Form 1040 or Form 1040-NR after year-end, with Form 1040-C tax credited as a payment.
Do F-1 students always need Form 1040-C?
No. F-1 students with only treaty-exempt scholarships and no taxable U.S. wages can usually file the shorter Form 2063.
Will the IRS stop me at the airport without a sailing permit?
Yes. Customs officers can flag departing aliens, and the IRS can pursue jeopardy assessment under IRC §6851 for unpaid tax.
Can my spouse and I file one Form 1040-C jointly?
Yes, if both spouses are resident aliens and meet the joint-filing rules of IRC §6013; nonresidents generally cannot file jointly.
Does Form 1040-C apply to U.S. citizens leaving the country?
No. U.S. citizens are not departing aliens, so they do not file Form 1040-C; expatriating citizens file Form 8854 instead.
Can I claim the standard deduction on Form 1040-C as a nonresident alien?
No, with one exception — students and business apprentices from India may claim it under Article 21 of the U.S.–India treaty.
Do I need to pay the full balance due before getting a sailing permit?
Yes, in most cases, unless you can post a bond or show the IRS that your departure does not jeopardize collection under IRC §6851(e).
Is a sailing permit valid for the whole tax year?
No. Each departure requires its own sailing permit, and you must file a new Form 1040-C if you leave the country more than once in a year.
Does Form 1040-C trigger the §877A expatriation tax?
No by itself, but if you are a long-term green card holder abandoning status, the §877A exit tax applies on a separate Form 8854.
Can I get a refund directly from Form 1040-C?
No. Refunds are claimed on your year-end Form 1040 or 1040-NR; Form 1040-C only computes prepayment.
Are gambling winnings reportable on Form 1040-C?
Yes. Nonresident aliens report U.S. gambling winnings as Group II income at the flat 30% rate, as confirmed in Park v. Commissioner.
