One of the most common and costly tax issues Canadians face with U.S. LLCs is double taxation.
To understand why this happens, we need to look at how each country views the same entity differently.
The Core Problem: Two Countries, Two Different Classifications
In the United States, a standard single-member LLC is treated as a “disregarded entity” for tax purposes.
This means:
- The LLC itself does not pay tax
- The owner reports all income personally
- It behaves like a sole proprietorship
So if the LLC earns $100,000, that income flows directly to the owner’s personal tax return.
However, Canada does not see it that way.
The Canada Revenue Agency (CRA) generally treats a U.S. LLC as a corporation, not a disregarded entity.
This creates an immediate mismatch:
- U.S. tax system: pass-through (sole proprietorship)
- Canadian tax system: corporation
And this mismatch is where the problem begins.
Example: How Double Taxation Happens
Let’s walk through a simplified scenario:
Year 1
- LLC profit: $100,000
- No distribution taken
- U.S. tax rate: 30%
In the U.S.:
- You pay $30,000 tax
- Remaining income is considered already taxed
In Canada:
- No dividend is received
- CRA treats the entity as a corporation
- No foreign tax credit is recognized yet
So far, only U.S. tax has been paid.
Year 2
- $75,000 is distributed to the owner
In the U.S.:
- No additional tax (already taxed in Year 1)
In Canada:
- This distribution is treated as a taxable dividend
- Tax rate assumed: 40%
- No matching foreign tax credit available
Result:
- $30,000 additional Canadian tax owed
The Final Outcome
Across both years:
- $30,000 paid to IRS
- $30,000 paid to CRA
- Total tax: $60,000 on $100,000–$175,000 of income depending on structure
This results in an effective tax rate that can approach or exceed 60%, depending on timing and structure.
The core issue is not bad tax rates—it’s classification mismatch between two systems.
In the next blog, we’ll look at the solution: how changing the tax treatment of the LLC can eliminate this mismatch and significantly reduce double taxation risk.
