If you prepare cross‑border corporate returns, that difference matters a lot. Get it wrong, and you either expose the client to a 4 percent tax you did not plan for or you miss the separate disclosure rules that actually live on Form 8833. The fix that year was simple, file Schedule V only for vessels with U.S. source gross transportation income, then handle treaty disclosure correctly on Form 8833, not Schedule V.
If you remember one thing, remember this, Schedule V reports vessels or aircraft for the section 887 4 percent regime, treaty disclosures belong on Form 8833.
Key Takeaways
- Schedule V, Form 1120‑F is used to list each vessel or aircraft that generated U.S. source gross transportation income subject to the section 887 4 percent tax, amounts in U.S. dollars, in English.
- Form 8833, not Schedule V, is where you disclose treaty‑based return positions under section 6114 or 7701(b), and the failure‑to‑disclose penalty under section 6712 is $10,000 per failure for corporations.
- File Schedule V with the Form 1120‑F return by the normal due date, generally month 4 if you have a U.S. office, month 6 if you do not, or on extension via Form 7004.
- If you qualify for the section 883 exclusion for international shipping or aircraft operations, you claim it on Schedule S, and you are not subject to the 4 percent tax, so Schedule V is not required for those excluded amounts.
- Protective filing rules for 1120‑F and the 18‑month timely filing window to preserve deductions live in Treas. Reg. §1.882‑4, and they can matter if you are unsure about permanent establishment or ECI.
What Schedule V Actually Covers, The Section 887 4 Percent Regime
Schedule V is a list, by vessel or aircraft, that ties to the 4 percent tax on U.S. source gross transportation income, USSGTI, under section 887. You complete a separate column for each vessel or aircraft with U.S.‑source transportation income that is not effectively connected and not excluded under section 883. The IRS asks you to present everything in English and in U.S. dollars.
What counts as USSGTI, in plain English? Transportation income, for example time charter, voyage charter, bareboat lease, or services directly related to the use of a vessel or aircraft, to the extent it is from U.S. sources. As a rule of thumb, half of transportation that begins or ends in the United States is U.S. source, subject to special rules for personal services. If that income is ECI, it is not part of USSGTI for section 887.
When You Must Attach Schedule V
You attach Schedule V to Form 1120‑F for any year the foreign corporation is actually subject to the section 887 4 percent tax. That is the critical trigger. The form itself sits alongside line 9 of Form 1120‑F, which reports gross transportation income. If you are under section 887 in that year, you must complete Schedule V and file it with the return.
When You Do Not File Schedule V
If you qualify for the section 883 exclusion for international shipping or aircraft operations, you claim that exclusion on Schedule S and do not owe the 4 percent tax. In that case, the section 887 tax does not apply to the excluded income, so Schedule V is not required for those excluded activities.
The Big Confusion, Schedule V Versus Form 8833
Here is the part that trips teams every March. Schedule V does not disclose treaty‑based return positions. That disclosure lives on Form 8833 under section 6114, with exceptions spelled out in regulations and publications. Corporations that fail to disclose a required treaty position face a separate assessable penalty under section 6712, $10,000 per failure, which the IRS may waive for reasonable cause and good faith.
To connect the dots, the Form 1120‑F instructions explicitly discuss using Form 8833 when you are claiming a treaty exemption, for example business profits not taxable because there is no U.S. permanent establishment, and even reference the treaty item on page 2, item W(1). None of that changes whether Schedule V is required, which only follows if section 887 applies.
Due Dates, Extensions, And Protective Filing
Filing timing is straightforward once you separate the concepts. If you maintain a U.S. office or place of business, Form 1120‑F is generally due on the 15th day of the 4th month after year‑end. If you do not have a U.S. office, it is due on the 15th day of the 6th month. If a due date falls on a weekend or legal holiday, the due date moves to the next business day. File Form 7004 by that original due date to extend the return. Schedule V rides along with the return on the same timeline.
There is another clock you cannot ignore, the timely filing rule to preserve deductions and credits against effectively connected income. Treasury regulations give foreign corporations an 18‑month window from the statutory due date to be treated as timely for deduction purposes, with a narrow waiver path if the corporation shows it acted reasonably and in good faith. When you are not sure about permanent establishment or ECI, a protective return within those rules is your safety net.

| Filing scenario | Due date without U.S. office | Due date with U.S. office | Extension action |
| Form 1120‑F and any required Schedule V | 15th day of month 6 after year‑end | 15th day of month 4 after year‑end | File Form 7004 by the original due date |
| Timely filing to preserve deductions under Reg. §1.882‑4 | Generally within 18 months of the statutory due date | Generally within 18 months of the statutory due date | Possible waiver for reasonable cause and good faith, facts and circumstances |
Protective Returns In Practice
If you determine initially that you have no ECI, for example because you believe there is no U.S. permanent establishment, the instructions advise filing a protective return to safeguard deductions should that view change on exam. The same instruction appears if you first believe your income is exempt by treaty. The protective return can be bare bones, with a statement that it is being filed to preserve rights under the regulation.
Step‑By‑Step, Completing Schedule V The Right Way
Use one column per vessel or aircraft that generated USSGTI subject to the 4 percent tax. Include the vessel’s Lloyds number or the aircraft registration number, the operator, and the owner. If you are a bareboat lessor, complete a separate column for each asset leased that produced USSGTI. If you operated vessels or aircraft, including time or voyage charters, do the same for each asset. If you provided services directly related to the use of a vessel or aircraft, for example terminal services or on‑board services, complete a separate column for each asset you serviced that produced USSGTI. All entries must be in English and in U.S. dollars.
Practical tip, maintain a simple crosswalk of voyage numbers, dates, ports, gross receipts, and whether the movement began or ended in the United States. That one pager shortens review time because reviewers can tie each vessel column on Schedule V to underlying invoices and manifests without hunting through emails.

Schedule V Versus Form 8833 Versus Schedule S
When you are wiring your close process, it helps to see these three side by side.
| Item | What it does | When it is required | Where it lives |
| Schedule V, Form 1120‑F | Lists vessels or aircraft for USSGTI subject to the section 887 4 percent tax | Required when section 887 applies in the tax year | Attach to Form 1120‑F with line 9 gross transportation income |
| Form 8833 | Discloses treaty‑based return positions under section 6114 or 7701(b) | Required unless an exception applies, for example certain FDAP rate reductions or small amounts, see regulations and Pub. 519 | Attach to the return that claims the treaty position, for corporations usually Form 1120‑F |
| Schedule S, Form 1120‑F | Claims the section 883 exclusion for international operation of ships or aircraft | Required to claim the section 883 exclusion, which removes the section 887 tax | Attach to Form 1120‑F |
Treaty Disclosure, Penalties, And How It Interacts With 1120‑F
Form 8833 is the disclosure vehicle for treaty‑based return positions. The regulations under section 6114 require disclosure when a treaty overrules or modifies a Code rule and reduces a tax, subject to stated exceptions. If a corporation fails to disclose a required position, section 6712 imposes an assessable penalty of $10,000 per failure, which may be waived for reasonable cause and good faith. That penalty is separate from any accuracy‑related penalties.
A simple way to confirm you are using the right form, the 1120‑F instructions point out that when income is exempt by treaty, you still file 1120‑F and attach Form 8833 if required, and the form’s page 2, item W(1), captures the treaty reference on the face of the return. None of this replaces Schedule V. Schedule V is only about USSGTI under section 887.
Exceptions To Filing Form 8833 You Should Know
The IRS lists certain exceptions, for example when you only claim a reduced rate of withholding on common FDAP items like interest or dividends, or when the total payments subject to disclosure are small, along with specific categories like dependent personal services or pensions. Always check the current instructions or Pub. 519 if you think an exception applies.
Review Checklist And Workflow Guardrails
Here is a simple checklist you can drop into your month‑end or year‑end binder. It reduces last‑minute chaos and review loops.
- Confirm whether any voyages, flights, or related services began or ended in the United States. Flag those revenue lines.
- Decide whether the section 883 exclusion applies. If yes, prep Schedule S and document ownership and equivalent benefit tests. If no, proceed to Schedule V.
- Build a one‑page vessel or aircraft index, voyage dates, ports, gross receipts, U.S.‑source determination.
- Populate Schedule V, one column per asset, in English and U.S. dollars.
- Review treaties. If any return position depends on a treaty, prepare Form 8833, tie it to the return, and reference the treaty in item W(1) on page 2.
- Check due dates and extension status, month 4 with a U.S. office, month 6 without, then Form 7004 if needed.
- If your PE or ECI status is uncertain, consider a protective return within the 18‑month window to preserve deductions, attach a brief statement.
Why Discipline Matters For Firms
If your firm struggles with bottlenecks in reviews, inconsistent workpapers, or resourcing swings during peak season, treaty and transportation filings get risky. That is where structure pays off, standard file naming, cross‑referenced vessel logs, and clear owner or operator details reduce review time and protect deadlines. If you maintain those habits, Schedule V becomes a data exercise, not a fire drill.
Treat Schedule V as a data schedule, and Form 8833 as a legal disclosure. Different purposes, different reviewers, different checklists.

FAQs
Does Schedule V disclose treaty positions?
No. Schedule V only lists vessels or aircraft that produced U.S. source gross transportation income subject to the section 887 4 percent tax. Treaty‑based return positions are disclosed on Form 8833 under section 6114 or 7701(b).
If I claim the section 883 exclusion, do I still file Schedule V?
If your income is excluded under section 883, you claim the exclusion on Schedule S. Because the section 887 tax does not apply to excluded income, Schedule V is not required for those amounts.
What is the penalty for not filing Form 8833 when required?
For corporations, the penalty under section 6712 is $10,000 per failure. The IRS can waive it for reasonable cause and good faith. This penalty is in addition to any other penalty.
When is Form 1120‑F due, and does that change Schedule V timing?
If you have a U.S. office, your return is due the 15th day of the 4th month after year‑end. If you do not, it is the 15th day of the 6th month. File Form 7004 by that date to extend. Schedule V follows the same deadlines because it attaches to Form 1120‑F.
What if I am unsure about permanent establishment or ECI?
File a protective return to preserve deductions, then evaluate facts as they develop. Regulations provide an 18‑month timely filing window, and a limited waiver path if you show reasonable cause and good faith.
