IRS Form 5472 Penalty Notice: What Canadian Business Owners Need to Know
By Arik Rozen, CPA, MBA · Virginia License #025991 · Updated October 2026
QUICK SUMMARY
Canadian owners of U.S. LLCs and C corps with 25% or more foreign ownership must file IRS Form 5472 every year -- failure triggers a $25,000 penalty per form, per year.
A Canadian CPA designation (CPA Canada) does not authorize practice before the IRS. Your Canadian accountant cannot represent you, cannot sign your U.S. returns, and cannot respond to IRS notices on your behalf.
The U.S.-Canada tax treaty (1980, updated 1995) is the most comprehensive the U.S. has signed -- but it covers income tax. It does not protect you from Form 5472 information return penalties.
Canada is the largest single source of foreign-owned U.S. entities. Delaware LLCs, Florida LLCs for real estate, Wyoming LLCs -- Canadians own them in large numbers and many are out of compliance.

WHO This Affects: Canadian Owners of U.S. Entities
If you are a Canadian resident or Canadian citizen who owns a U.S. LLC or C corporation with 25% or more foreign ownership, the IRS requires you to file Form 5472 -- the Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business.
This is not a tax return in the traditional sense. It is an information return -- meaning it reports transactions between your U.S. entity and related foreign parties. The IRS does not need to owe you a refund or bill you for taxes to penalize you for missing it. The penalty is automatic: $25,000 per form per year, with continuation penalties of $25,000 for every 90-day period the failure continues after IRS notice.
Common situations where Canadians encounter this obligation include: a single-member LLC used for consulting or e-commerce, a Delaware holding company, a Florida or Arizona LLC purchased for U.S. real estate investment, or a Wyoming LLC set up for privacy and asset protection. If you own 25% or more of that entity, Form 5472 applies.
WHAT Triggered Your Penalty Notice
Most Canadian business owners who receive an IRS penalty notice for Form 5472 fall into one of four categories.
COMMON TRIGGERS
You filed a U.S. corporate tax return (Form 1120) but forgot to attach Form 5472.
Your U.S. LLC had no income and you assumed it was exempt from U.S. filing requirements -- it is not. A disregarded LLC owned by a foreign person still requires a pro forma Form 1120 with Form 5472 attached.
Your Canadian accountant prepared your Canadian T1 or T2 return but was not aware of, or not qualified to handle, the separate U.S. information return requirement.
You dissolved or wound down the U.S. entity without filing the final Form 5472, triggering penalties on the year of dissolution.
THE CPA Name Trap: Canadian CPA vs. U.S. CPA
This is the most common -- and most costly -- misunderstanding for Canadian business owners with U.S. entities.
Both Canada and the United States use the title "CPA" -- Chartered Professional Accountant in Canada, Certified Public Accountant in the U.S. The acronym is identical. The professional licenses are not.
A Canadian CPA -- even a highly experienced one, even a partner at a large firm -- is not authorized to practice before the IRS. Under IRS Circular 230, representation rights before the IRS are limited to U.S. attorneys, U.S. CPAs, and enrolled agents licensed by the IRS. A Canadian CPA holds none of these credentials.
What this means in practice: your Canadian accountant cannot sign your U.S. tax returns, cannot respond to an IRS notice on your behalf, cannot submit a penalty abatement request, and cannot represent you in an IRS examination. If they attempt to do so, they are acting outside their authority -- and the IRS will not recognize them.
CPA CANADA VS. U.S. CPA: KEY DIFFERENCES
Canadian CPA (CPA Canada): Licensed by a provincial body (CPA Ontario, CPA Quebec, etc.). Authorized to practice before the CRA. Not authorized to practice before the IRS.
U.S. CPA: Licensed by a U.S. state board (e.g., Virginia Board of Accountancy). Authorized under IRS Circular 230 to represent clients before the IRS, sign U.S. returns, and submit penalty abatement requests.
The titles look the same. The authority is completely different. For IRS matters, only a U.S.-licensed practitioner under Circular 230 can represent you.
WHY the U.S.-Canada Tax Treaty Does Not Help You Here
The Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital, originally signed in 1980 and updated most recently in 1995, is widely considered the most comprehensive bilateral tax treaty the United States has ever negotiated. It covers double taxation on income, rules for permanent establishments, reduced withholding rates on dividends, interest, and royalties, and relief from certain capital gains taxes.
It does not address information return penalties.
Form 5472 is not an income tax. It is a structural reporting requirement under IRC Section 6038A. The treaty's income tax provisions have no bearing on whether the IRS can impose the $25,000 penalty. Many Canadian business owners -- and, frankly, some Canadian accountants -- assume that the treaty provides a layer of protection against U.S. penalties. It does not in this context.
Additionally, for Canadians investing in U.S. real estate through a U.S. LLC, the intersection with FIRPTA (Foreign Investment in Real Property Tax Act) creates a second compliance layer.
FIRPTA governs withholding on the sale of U.S. real property by foreign persons, while Form 5472 governs the annual reporting of transactions between your LLC and you as a foreign owner. Both apply -- independently. Meeting one obligation does not satisfy the other.
HOW to Respond to an IRS Form 5472 Penalty Notice
When you receive an IRS penalty notice related to Form 5472, the clock starts immediately. Do not ignore it. Do not forward it to your Canadian accountant assuming they can handle it. Here is the sequence our team follows for Canadian clients.
Step 1: Identify the penalty type and tax year.
The IRS notice will reference a specific EIN, tax year, and penalty amount. Common notice types are CP15 and Letter 3423. Confirm whether you received a single-year penalty or penalties spanning multiple years. Each unfiled year is a separate $25,000 exposure.
Step 2: Gather the missing returns.
A penalty abatement request is only viable once the underlying returns are filed or in progress. Our team prepares the delinquent Form 5472 and any required Form 1120 for each year at issue. For disregarded LLCs, this means a pro forma Form 1120 with Form 5472 attached, even with zero income.
Step 3: Submit a penalty abatement request.
The IRS grants penalty relief under two main bases: First Time Abatement (FTA) and reasonable cause. For many Canadian-owned entities, reasonable cause is the stronger argument -- specifically, that the taxpayer relied on a Canadian advisor who was unaware of or unqualified to advise on U.S. information return requirements. This is a recognized reasonable cause argument when properly documented.
Step 4: Respond within the deadline.
IRS penalty notices specify a response deadline, typically 60 days. Missing this deadline forfeits certain rights to appeal without going through Tax Court. Our team responds on your behalf under the Circular 230 authority of our licensed U.S. CPA.
WHY form5472.online vs. a Large CPA Firm
Large cross-border accounting firms do handle Form 5472 issues -- but they handle them as one item in a broader engagement. Expect to pay an estimated $2,000 to $5,000 in fees for what is often a straightforward penalty abatement on a disregarded entity with no revenue. The work is not complex. The billing rate is.
form5472.online specialists handle only Form 5472 issues. That focus means our team knows every variation of this penalty -- from single-member LLCs with zero transactions to multi-year delinquencies across multiple entities -- and our pricing reflects the actual scope, not a large firm's overhead structure.
For Canadian clients specifically, our team understands the CRA-IRS disconnect, the CPA designation confusion, and the treaty misunderstandings that lead to these filings being missed in the first place. We do not need to be educated on your situation -- we see it regularly.
FREQUENTLY Asked Questions: Canadian-Specific
Can my Canadian CPA help me respond to an IRS Form 5472 penalty notice?
No. A Canadian CPA is not authorized to practice before the IRS under Circular 230. They can help you understand the situation and gather documents, but they cannot sign correspondence to the IRS, submit an abatement request on your behalf, or represent you if the matter escalates. You need a U.S. CPA, enrolled agent, or U.S. tax attorney for those steps.
Does FATCA affect my Form 5472 obligation?
FATCA (Foreign Account Tax Compliance Act) and Form 5472 are separate frameworks. FATCA requires foreign financial institutions to report U.S. account holders to the IRS, and U.S. persons to report foreign financial accounts on Form 8938. Form 5472 is a separate obligation focused on the transactions between your U.S. entity and related foreign parties. The two can overlap in a complex structure, but satisfying FATCA reporting does not eliminate your Form 5472 obligation, and vice versa.
My Quebec accountant has a CPA designation. Is that different?
No. CPA Quebec is the provincial professional order for Chartered Professional Accountants in Quebec. Like CPA Ontario, CPA Alberta, and the other provincial bodies, CPA Quebec issues a Canadian professional designation. It does not confer IRS practice rights. The answer is the same whether your accountant is in Montreal, Toronto, Calgary, or Vancouver: without a U.S. CPA license or enrolled agent credential, they cannot represent you before the IRS.
I owned a U.S. LLC for several years and never filed Form 5472. What is my total exposure?
The $25,000 penalty applies per form, per year. If you owned a qualifying U.S. LLC for five years without filing, your theoretical exposure is $125,000 -- before continuation penalties. The IRS does have processes for resolving multi-year delinquencies, including reasonable cause abatement and streamlined procedures in some cases. The earlier you act, the more options are available. Our team has resolved multi-year delinquencies for Canadian clients across a range of entity types.
