Forms 1120, 1120-F and 5472: which a Canadian-owned business files in the US
A US corporation files Form 1120 on its worldwide income. A foreign corporation — a Canadian company doing business in the United States — files Form 1120-F on the income effectively connected with that business, and files it even when the treaty exempts the profits because no permanent establishment exists, since a protective return preserves the deductions and the treaty position. Form 5472 is the information report a US corporation that is foreign-owned, or a foreign corporation engaged in US business, files to disclose transactions with related parties, and its penalty for late filing is fixed and severe.
The recurring questions are whether US activity has crossed from selling into the country to doing business in it, whether a permanent establishment exists under the treaty, how much of the profit is attributable to it, and whether the state — which does not always follow the treaty — has a separate claim. Intercompany charges between the Canadian parent and its US operation are the transfer-pricing question inside the corporate one.
- Determination of whether US activity is a trade or business and whether a treaty permanent establishment exists.
- The federal return that follows — 1120, 1120-F or a protective 1120-F — with the treaty-based return position disclosed.
- Form 5472 for related-party transactions, state filings where states do not follow the treaty, and the branch-profits and withholding questions on repatriation.
My Canadian company sells to US customers but has no office there. Do we file? A protective 1120-F is usually filed to preserve the treaty position and deductions; whether tax is owed turns on whether a permanent establishment exists, which depends on where contracts are concluded and where staff work.
What is Form 5472 for and who files it? It discloses transactions between a US corporation and its foreign owners or related parties, or between a foreign corporation's US business and related parties; it is an information return with a fixed penalty for each late or incomplete form.

Key U.S. Corporate Tax (1120, 1120-F & 5472) Tax Terms, Defined
- T1135
- The foreign income verification statement Canadian residents file once specified foreign property passes $100,000 of cost at any time in the year (CRA, 2025 tax year).
- Tax Treaty
- The bilateral agreement that allocates taxing rights between two countries and relieves double taxation.
- Withholding Tax
- Tax deducted at source on cross-border payments — Canada's 25% Part XIII rate is often reduced by treaty.
Foreign-owned U.S. corporations and U.S. branches carry information-return exposure measured in US$25,000 penalties per missed form — 5472 discipline is not optional.
U.S. real property brings its own regime: FIRPTA withholding on sale (typically 15% of gross price unless reduced by certificate), state filings, and Canadian foreign tax credit coordination on the same gain. Engagements are quoted as a fixed fee for a defined scope, and reviews of prior-year filings are included where earlier positions affect the current one.
U.S. Corporate Tax (1120, 1120-F & 5472) — published fixed fees
Covers: A state-by-state review of sales, transactions, employees and inventory against each state's own tests, with the registration and collection start dates identified.
What moves it up: The number of states in scope. Each is tested on its own rules with its own thresholds, and a single remote employee can bring three taxes in one state.
See this fee pageCovers: The foreign corporation's US return with the related-party information reporting, filed on time so deductions and treaty positions are preserved rather than argued for.
What moves it up: Dormancy is not a discount. A foreign-owned US entity with no activity still owes the information return, and the penalty for missing it does not scale with turnover.
See this fee pageCovers: A written opinion on whether the activity creates a taxable presence, what would be attributable to it if it did, and what could be changed to alter the answer.
What moves it up: How many people and places are involved. One employee working from home is one analysis; a sales team, a warehouse and a contractor with signing authority is several.

U.S. Corporate Tax (1120, 1120-F & 5472) Frequently Asked Questions
At minimum: prior-year returns and notices of assessment, your bank and credit-card statements for the fiscal period, payroll records if you have employees, and GST/HST filings. We send a checklist tailored to your situation after the first call to our 24-hour helpline.
Most engagements are completed within 3 to 5 business days once your documents are complete. Catch-up work covering multiple years takes longer, and we tell you the realistic timeline before you commit rather than after.
We respond on your behalf at no extra charge for any return we prepared. Every figure we file is supported by documentation retained in your file, which is what turns a CRA review from a crisis into correspondence. See how our CRA audit support works.
Yes. The late-filing penalty is 5% of the balance owing plus 1% of that balance for each full month the return is late, to a maximum of 12 months (CRA, 2025 tax year). Interest is what compounds, daily, on top. We prioritise catch-up work and, where eligible, file under the CRA's Voluntary Disclosures Program to reduce penalties.
Yes. We work with clients wherever they live, from our offices in India, the USA, Canada and the UAE, and your location does not change the price or the service. Browse our coverage by country and region to find yours.
We work across construction, healthcare, e-commerce, professional services, restaurants, real estate, transportation, technology and non-profits, each with its own deduction profile and the points tax authorities scrutinise. See all industries we serve.
Software applies the rules you told it about. It does not ask whether a treaty caps the withholding on that payment, whether the foreign credit was claimed in the right country, whether an information return was due on an account that earned nothing, or whether your related-party pricing is documented. Those are the questions that move the number on a cross-border file.
Our U.S. corporate tax (1120, 1120-f & 5472) services include complete filing, compliance management, and strategic advice customized to Canadian tax laws.
You can start by calling our 24-hour helpline on +1 (416) 619-0068 or sending the form. We will review your files, provide a fixed quote, and start working immediately.
A taxable presence in another country under the treaty — typically a fixed place of business such as an office, branch, factory or workshop, or a dependent agent habitually concluding contracts on your behalf. Some treaties add a services test measured in days. Purely preparatory or auxiliary activity is excluded, but that carve-out is narrower than it sounds: one senior employee working from home in the other country, with authority, has been enough. See business profits and permanent establishment.
Not at full rates if the relief is claimed. The paying country usually withholds at source, capped by treaty where one applies and the paperwork is in place; your residence country then taxes the dividend and credits the foreign withholding against its own charge. Where the withholding exceeded the treaty rate because no declaration was filed, the excess is recovered from the paying country, not credited at home. See the dividends article.

Files that look like this one
Foreign-owned US subsidiary's related-party transactions reported for the first time
A foreign-owned US subsidiary that had not previously reported its transactions with its foreign parent needed that reporting prepared before the deadline, since the obligation applies even to a subsidiary with modest activity. We reviewed the subsidiary's related-party transactions and prepared the required reporting.
US branch of a foreign corporation reviewed for its separate branch-level filing
A foreign corporation operating through a US branch needed the branch's own separate filing reviewed, since a branch carries its own reporting distinct from a US subsidiary's ordinary corporate return. We reviewed the branch's activity and prepared the filing the branch structure specifically required.
Foreign parent's US subsidiary corporate return prepared alongside its intercompany reporting
A foreign parent's US subsidiary needed its corporate income tax return prepared alongside the separate reporting on its transactions with the parent, so the two filings were consistent with each other. We prepared both filings from the same underlying figures so neither return contradicted the other.
A US LLC Owned From Canada
The two countries classify the vehicle differently, so relief that ought to apply frequently does not and the same profit can be taxed in both hands. The engagement examines whether the structure can be changed and what the change itself costs.
Read how this one runsNever Filed a US Return — and Only Just Found Out
Born in the United States, left as an infant, and told by a bank that the returns were owed all along. The work is sequencing: establish which years are actually open, choose the catch-up route on the facts rather than filing quietly, and claim the exclusions and credits that were never taken.
Read how this one runsUS Estate Tax on Assets a Canadian Did Not Know Were Exposed
US shares and US real estate sit inside the US estate tax net regardless of where the owner lives. The treaty provides relief that is proportionate rather than automatic, and the calculation depends on the worldwide estate.
Read how this one runsWhether Documentation Was Required At All
The obligation turns on the transactions that actually happened rather than on the size of the group, and the penalty for contemporaneous documentation is charged by reference to the adjustment. The review establishes which side of the line the company sits.
Read how this one runsTreaty Relief Claimed on a Cross-Border Estate
The estate article can extend a proportionate credit where the two systems would otherwise both tax the same asset. Claiming it requires a valuation and a disclosure the estate may not expect to make.

Industries & Client Types We Serve Worldwide
Cross-border tax for sellers shipping worldwide: marketplace withholding, foreign registrations and inventory nexus handled before they become audits.
Marketplaces withhold, remit and report in their own right, so the tax position of a single sale is decided by where the stock sat, where the buyer was and which platform collected — not by where the company is registered. We reconcile the platform's own filings against the returns before either is submitted.
