The U.S.-Canada Income Tax Treaty prevents double taxation through foreign tax credits. When you earn income taxed by both countries, you can claim a credit in your country of residence for taxes paid to the other country. For instance, as a U.S. resident with Canadian income, you would first report and pay tax on the income in Canada, then report it on your U.S. return and claim Form 1116 foreign tax credits. The credit is limited to your U.S. tax liability on the foreign income and must be calculated separately for different income types.

RRSPs receive special treatment under the tax treaty. While Form 8891 filing was eliminated after 2014 for most taxpayers, you must still report RRSP earnings on Form 8938 if your balance exceeds reporting thresholds. You also need to include RRSPs on FinCEN Form 114 (FBAR) if your total foreign accounts exceed $10,000. Most taxpayers receive automatic deferral of RRSP income taxation through the treaty, though some prior year elections may need Form 8891.

TFSAs don’t receive special treaty benefits and create complex reporting requirements for U.S. taxpayers. You must report and pay U.S. tax on TFSA earnings annually, include the account on Form 8938 and FBAR if applicable, and possibly file Forms 3520 and 3520-A due to foreign trust classification. Many tax professionals recommend closing TFSAs before becoming a U.S. resident to avoid these complications.

For RRSPs, consider your current and expected future tax rates in both countries, withdrawal withholding rates (5-30%), impact on retirement benefits, and currency exchange implications before withdrawing. RRSP withdrawals are taxed as ordinary income for U.S. residents, but you can claim credit for Canadian withholding tax. For TFSAs, consider withdrawing before U.S. residency to avoid complex reporting requirements and annual U.S. taxation of earnings.

To establish non-resident status with the CRA, you need to:

1. File Form NR73 to determine residency status
2. Submit Form NR301 to Canadian payers for proper withholding rates
3. File a final Canadian tax return showing your departure date
4. Report any deemed disposition of taxable Canadian property

The CRA evaluates both primary and secondary residential ties. Primary ties include maintaining a home, having a spouse or dependents in Canada, or keeping personal property in Canada. Secondary ties include Canadian bank accounts, driver’s license, social memberships, and business relationships. The more ties you maintain, the more likely the CRA will consider you a resident for tax purposes.

U.S. tax residency is primarily determined through the Substantial Presence Test, which counts:

• All days in the current year
• 1/3 of days in the first preceding year
• 1/6 of days in the second preceding year

If your total equals or exceeds 183 days, you’re generally considered a U.S. resident for tax purposes. However, treaty tiebreaker rules may apply if you’re considered a resident of both countries.

You must file Canadian returns if you:

• Earn Canadian-source employment or self-employment income
• Sell taxable Canadian property
• Need to claim a tax refund
• Want to maintain Canadian tax credits or benefits
• Receive Canadian rental income (optional Section 216 election)

U.S. tax benefits may include the Foreign Earned Income Exclusion (up to $112,000 for 2022), Foreign Housing Exclusion, foreign tax credits, treaty-based positions, and moving expenses for job-related relocations. As a Canadian non-resident, you may still claim prorated personal credits, Canadian pension contribution deductions, moving expenses within Canada, charitable donations, and rental property expenses.

Maintain comprehensive records including:

• Travel logs documenting presence in each country
• Documentation of residential ties
• Tax returns and supporting documents from both countries
• Foreign tax credit documentation
• Currency exchange records
• Investment account statements

These records are crucial for supporting your tax positions and responding to any tax authority inquiries.
