US-Canada Tax Treaty: What Americans Abroad Need to Know
The US-Canada tax treaty is one of the most important treaties for Americans abroad, given the large American expat community in Canada. The saving clause preserves the US right to tax its citizens. The treaty has unique provisions regarding RRSPs and other Canadian retirement accounts.
Key Treaty Provisions
The US-Canada tax treaty covers:
- Income from employment — Taxed where the work is performed
- Dividends — Reduced withholding rates (15% or 5%)
- Interest — Reduced withholding rate (0% for certain interest)
- Royalties — Reduced withholding rate (0% for certain royalties)
- Pensions — Generally taxed only in the country of residence
- Social Security — Taxed only by the paying country
- Capital gains — Taxed where the taxpayer is resident
The Saving Clause
The saving clause preserves the US right to tax its citizens and residents. You still file a US tax return and owe US tax on worldwide income even if you live in Canada.
RRSP and TFSA
The US-Canada tax treaty has a unique provision regarding RRSPs: RRSP contributions may be deductible on your US return (unlike most foreign pension contributions). However, RRSP distributions are taxable in the US.
TFSAs (Tax-Free Savings Accounts) are NOT recognized as tax-free by the US. TFSA income is taxable on your US return. The treaty does not change this.
Residency Tie-Breaker Rules
If you are considered a tax resident of both the US and Canada, the treaty provides tie-breaker rules:
- Permanent home
- Center of vital interests
- Habitual abode
- Nationality
- Mutual agreement
Pensions & Retirement Income
Under the treaty, pensions are generally taxed only in the country of residence. For Americans in Canada:
- US Social Security is generally taxable only in the US
- US pensions and IRAs are generally taxable only in the US
- Canadian pensions (CPP, RRSP distributions) are taxable only in Canada
Totalization Agreement
The US-Canada totalization agreement coordinates social security coverage and prevents double social security taxation.
What the Treaty Does NOT Do
- Does not exempt US citizens from US tax (saving clause)
- Does not eliminate FBAR or FATCA reporting
- Does not make TFSAs tax-free in the US
- Does not change your US filing obligations
Practical Implications for Americans in Canada
Canada's high tax rates (up to 53.53%) make FTC very valuable. The RRSP provision is a unique benefit. The treaty's main practical benefit is reduced withholding on Canadian-source income and RRSP deductibility.
For most Americans in Canada, FTC is more valuable than FEIE due to high Canadian rates.
When to Get Professional Help
You should consider professional help if you have questions about treaty benefits, RRSP/TFSA reporting, pension taxation, or cross-border income.
