Accountably Editorial Team 12 min read Dec 11, 2025 Updated Dec 11, 2025
A client once called me from an airport check‑in line, suitcase in one hand, rising panic in the other. He had just learned he needed a “sailing permit,” the IRS confirmation that you estimated your year’s income, paid what you owe, and are cleared to depart.

He had not filed Form 1040‑C. The flight was boarding, the clock was loud, and that sinking feeling was real. If you are reading this before you pack, good. You can skip the scramble and walk into your departure with a plan.

Form 1040‑C is how you report what you already earned and what you reasonably expect to receive for the rest of the year, then settle any balance before you leave. In many cases, you visit an IRS Taxpayer Assistance Center, present your packet, and receive a signed certificate of compliance, also called a sailing or departure permit. You still file your regular annual return later.

Key Takeaways

  • You generally must obtain a sailing or departure permit before leaving the U.S. You get it by filing Form 1040‑C, or if you qualify, Form 2063, and resolving any tax due.
  • The certificate is issued through an IRS office visit. Bring identification, income records, and payment proofs to speed things up.
  • Form 1040‑C is not your annual return. You still file Form 1040 or 1040‑NR on time, and payments made with 1040‑C become a credit on that return.
  • For nonresidents, many portfolio items are taxed at a flat 30% unless a treaty lowers the rate. Effectively connected income uses graduated rates.
  • Nonresidents usually do not owe self‑employment tax, except when a Social Security totalization agreement places them under the U.S. system.

What Form 1040‑C Is and Who Must File

Form 1040‑C is the Departing Alien Income Tax Return. You use it to report income received and reasonably expected during the entire year of departure, then you pay any balance the form shows, unless the IRS concludes payment is not at risk. Once an IRS agent signs the certificate of compliance section, that signed page is your sailing or departure permit.

Who typically files

  • You file 1040‑C if you need a permit and do not qualify for the short Form 2063.
  • Residents follow the 1040 rules for computation, nonresidents follow 1040‑NR rules and treaty provisions where applicable.

Plain reminder You still file your annual return, Form 1040 or 1040‑NR, by the normal due date even after you depart. Any payment with 1040‑C becomes a credit on that return.

When Form 2063 Applies Instead

Form 2063 is a short statement without a tax computation, available only in limited cases, for example no taxable income for the current and prior year, or a resident whose departure will not hinder collection. If the IRS suspects someone is leaving to avoid paying tax, that person must file 1040‑C.

When and Where To File Before Departure

This is an in‑person process. You go to an IRS Taxpayer Assistance Center to file 1040‑C or 2063, usually within 30 days of travel, and the IRS recommends arriving at least 2 weeks before you leave. Book an appointment through the IRS TAC system, bring a complete packet, and be prepared to pay if the IRS determines payment is required to protect collection.

Pro move Time your visit after you have clean year‑to‑date numbers and clear forecasts. A tidy packet makes the appointment quicker and the outcome smoother.

Documents and Information You Will Need

Think of 1040‑C as a mini year‑end close. The better your binder, the faster your permit.

Bring these if they apply: passport and visa or green card, I‑94, prior two years of U.S. returns and payment proofs, a year‑to‑date wage statement, a self‑employment income and expense statement, records for gains or losses, scholarship or fellowship documents, proof of estimated payments, treaty support, your ticket showing departure date, and your SSN or ITIN documentation.

Identification and Visa Details

You will provide your full legal name, SSN or ITIN, U.S. and foreign addresses, visa class, passport number, country of issuance, date of arrival, and expected date and port of departure. Keep I‑20, DS‑2019, or I‑797 notices handy if they help confirm presence and status.

Item Purpose Source
Legal name, SSN or ITIN Tax identification Passport, SSA or IRS
U.S. and foreign addresses Contact and exit details Personal records
Visa and status history Residency and treaty review Passport, I‑94
Departure date and port Appointment timing, certificate window Ticket, itinerary
Immigration documents Presence and status support USCIS and CBP records

Income Records and Estimates

Pull complete year‑to‑date numbers and project the rest of the year. Include wages, consulting and business receipts, rent, interest, dividends, and expected bonuses tied to services already performed. Keep notes that tie each estimate to a pay stub, contract, bank statement, or prior‑year pattern, so you can reconcile at tax time.

Practical tip Create one simple worksheet per income stream with columns for paid to date, expected later, and the document you used. TAC visits move faster when your packet tells a clear story.

Tax Payments, Credits, and How the IRS Applies Them

Bring W‑2 and 1099 statements that show withholding, plus proof of estimated and prior payments. On 1040‑C, those amounts reduce what you need to pay at the TAC. Refundable and nonrefundable credits follow the same rules you will apply on your annual return. If payments exceed the expected tax, you can request a refund or apply it to next year. If you owe, plan to pay before you leave unless the IRS determines collection is not at risk.

Important Form 1040‑C is not the last word. When you file your annual return, you reconcile the year with actual forms. The tax you paid with 1040‑C becomes a credit on that final return.

How To Estimate Your 2025 Income and Tax For Form 1040‑C

Think like a controller closing the books. First, total what you earned so far. Second, forecast what you will receive through December 31. Use pay stubs, employer confirmation for bonuses, bank statements for interest, brokerage records for dividends or gains, and invoices or contracts for business income. Your target is a reasonable estimate that follows resident or nonresident rules and any treaty article you can support.

Wages Before and After Departure

  • Count salary, bonuses, and tips for the entire year. If a bonus will be paid after you leave but relates to work already performed, include it, and bring an employer letter if possible.
  • Confirm year‑to‑date wages and withholding with your latest pay statement. Watch for stock compensation vesting that can create taxable income later in the year.
  • For nonresidents, apply 1040‑NR sourcing and treaty rules. For residents, use 1040 rules and brackets.

Self‑Employment Income and SE Tax

  • If you are a resident for the year, compute self‑employment tax on net earnings of 400 or more, and consider Additional Medicare Tax thresholds as usual.
  • If you are a nonresident, you generally do not owe self‑employment tax, unless a totalization agreement places you under the U.S. Social Security system. If that applies, compute SE tax on Schedule SE and attach it to 1040‑NR.

Quick check W‑2 wages are not subject to SE tax, so do not double count. The wage base rules already coordinate Social Security between wages and self‑employment.

Investment Income and Withholding

  • Nonresident portfolio income that is not effectively connected, like many dividends, is generally taxed at 30%, or a lower treaty rate, and is reported on Schedule NEC of Form 1040‑NR. Effectively connected income uses graduated rates similar to residents.
  • Some U.S. real property income for nonresidents can be elected as effectively connected under section 871(d), which changes the rate structure and allows deductions.

Deductions, Credits, and Coordinating Payments

  • Subtract only the adjustments and deductions you actually qualify for, then apply credits you can support. Nonresidents have more limited credits than residents, so check 1040‑NR rules first.
  • Reconcile withholding and estimated payments made to date. Any shortfall is usually due at the appointment. Keep official payment confirmations with your file.

Resident vs. Nonresident Rules You Must Apply

Start with residency testing, the green card test or substantial presence test, then apply the correct scope of income.

Status Scope of Income Primary Annual Return Key References
Resident Worldwide income 1040 or 1040‑SR Publication 519
Nonresident U.S. source income plus effectively connected business income 1040‑NR Publication 519, 1040‑NR instructions
Dual‑Status Split rules across the year 1040 with 1040‑NR statement Publication 519
Treaty Claim Treaty article can override default rules 1040‑NR or 1040 Publication 519, treaty text

Residents are taxed on worldwide income. Nonresidents are generally taxed only on U.S. source income and effectively connected business income, with FDAP items often at 30%, unless a treaty changes the rate.

Special timing note for 2025 If you depart between January 1 and April 15, 2025, you must still file your 2025 annual return and pay any tax due by the regular due date.

Where To File and How To Get Your Sailing or Departure Permit

Plan on an in‑person filing at a Taxpayer Assistance Center. You will file Form 1040‑C, or Form 2063 if you qualify, and present your documentation. If approved, the IRS signs the certificate of compliance, and your copy serves as your sailing or departure permit. The certificate can apply to later departures in the same calendar year, subject to revocation if the IRS believes collection is at risk.

Confidence boost If you demonstrate that you intend to return and that your departure does not jeopardize collection, the IRS may issue the permit without requiring payment at the appointment. You must be current on all required filings and balances.

Step‑By‑Step Filing Workflow To Obtain Your Departure Permit

  • Confirm you need a permit If you are not in an exempt category, you must obtain a certificate of compliance before you leave.
  • Lock your residency status and treaty position Decide if you are resident, nonresident, or dual‑status, then note any treaty article you will claim and bring documents that support it.
  • Build your document kit Include ID and visa records, prior two years of returns, year‑to‑date wage statement, self‑employment ledger if applicable, proof of estimated payments, capital transaction records, scholarship or fellowship letters, treaty support, your ticket, and SSN or ITIN proof.
  • Estimate full‑year income and tax Add year‑to‑date amounts plus reasonable forecasts for the rest of the year. Apply resident or nonresident rules, coordinate SE tax if applicable, and apply treaty rates when you qualify.
  • Visit the TAC and file Arrive with a clean packet. Be prepared to pay if the IRS determines payment is needed to protect collection for this departure.
  • Keep the signed certificate When the IRS signs the certificate of compliance, keep your copy with your travel documents.
  • After you depart, file your annual return You still file 1040 or 1040‑NR by the regular deadline. Your 1040‑C payment is a credit on that return.

Common Mistakes and How To Avoid Them

  • Waiting too long to book your TAC visit. Appointments are required and calendars can fill. Aim for the 2‑week mark inside the 30‑day window.
  • Treating 1040‑C as your annual return. It is not. You must still file 1040 or 1040‑NR later and reconcile.
  • Ignoring income expected after departure. Include bonuses already earned, accrued interest, or other amounts tied to services already performed.
  • Misapplying SE tax. Residents compute SE tax on net earnings. Most nonresidents do not, unless covered by a totalization agreement.
  • Missing treaty paperwork. If you rely on a treaty rate or exemption, bring the article citation and support, or withholding may default to 30%.

Quick checklist before your TAC visit

  • Identity and visa documents
  • YTD wage statement or self‑employment ledger
  • Proof of estimated payments and withholding
  • Treaty support, if claimed
  • Ticket confirming your travel date

  • Form 2063, short form used in limited cases with no computation.
  • Form 4868, extension for your annual return, not a substitute for 1040‑C.
  • Form 1040‑NR, nonresident annual return with Schedule NEC for FDAP income.

Practical Examples

Example 1, H‑1B engineer leaving in August You earned wages through August and expect a December bonus for work completed by July. Include the bonus in your 1040‑C estimate, attach an employer letter if possible, and apply resident or nonresident rules based on your status. Withholding to date reduces what you pay at the TAC.

Example 2, Visiting researcher on J‑1 with a treaty You have scholarship payments and a treaty exemption. Bring the grant letter, treaty citation, and a year‑to‑date statement. The TAC will expect to see your basis for the treaty claim.

Example 3, Consultant with 1099 income, nonresident As a nonresident, you generally do not owe SE tax unless a totalization agreement places you under U.S. Social Security. Confirm coverage before the appointment and plan your payment method.

SEO‑Friendly Subtopics You Might Be Searching For

Do I always have to pay at the appointment

Not always. If you show that your departure does not jeopardize collection and you intend to return, the IRS may issue the permit without payment at the visit. You must be up to date on all required filings and balances.

Can I mail Form 1040‑C instead of visiting a TAC

Plan on an in‑person TAC filing. The certificate of compliance is issued by an IRS agent, and the physical signed copy is your permit.

What if I discover a change after I leave

File your annual return as usual. Recompute the year with actual forms. The payment made with 1040‑C becomes a credit, and you settle any difference then.

For Accounting Firms and Mobility Teams

If you manage multiple departures, the bottleneck is not demand, it is delivery. The way through is a disciplined packet that reviewers can clear quickly, a treaty support index, and a standard TAC appointment pack your preparers can assemble in under an hour. This reduces rework and keeps partners out of review loops during peak weeks.

Accountably helps firms build that kind of structure. We design SOPs for 1040‑C and 2063 workflows, standardize workpapers, and, when you need true capacity, integrate trained offshore teams that work inside your tools under predictable SLAs. Use us when delivery breaks under growth, not as a resume drop. Mentioning us lightly here is enough, because this article is about helping you obtain the permit the right way.

Frequently Asked Questions

What is Form 1040‑C

It is the IRS Departing Alien Income Tax Return you file before leaving the U.S. to estimate your year’s income and settle expected tax. The IRS signs a certificate of compliance that becomes your departure permit, and you still file your annual return later.

What is Form 2063 and how is it different

Form 2063 is a short statement without a tax computation, allowed only in specific situations, for example no taxable income for the current and prior year, or a resident whose departure will not hinder collection. If you do not qualify, you must file 1040‑C.

Do nonresidents pay self‑employment tax

Generally no. A nonresident does not owe SE tax unless a totalization agreement places them under the U.S. system. If that applies, compute SE tax on Schedule SE and file it with Form 1040‑NR.

What about investment income withholding

Nonresident portfolio income that is not effectively connected is typically taxed at 30%, or a lower treaty rate, while effectively connected income is taxed at graduated rates. Report non‑ECI on Schedule NEC of Form 1040‑NR.

Can a certificate cover multiple trips in the same year

Yes. A certificate issued with Form 1040‑C can apply to later departures in the same calendar year, unless the IRS revokes it because collection appears at risk.

Conclusion

If you remember only one sequence, remember this. Lock your status, build a simple estimate, and schedule your TAC visit about 2 weeks before you fly, within the 30‑day window. Bring a clean set of documents and, if needed, certified funds. File 1040‑C or 2063, walk out with the signed certificate, then file your annual return on time and use the 1040‑C payment as a credit. Do this, and your departure feels calm, not chaotic.
