Confirm Your Non-Resident Status First

Before filing any non-resident tax return, confirm your residency status with CRA using the residential ties test — dwelling, spouse, dependants, and secondary ties like bank accounts and driver's licence. Filing as a non-resident when CRA considers you a resident means your worldwide income is taxable in Canada, creating massive reassessments with compound interest on unreported amounts.

File T1-NR to Claim Deductions

If CRA withheld 25% Part XIII tax on your Canadian income, filing a T1-NR non-resident tax return lets you report actual income and claim eligible deductions and credits — potentially recovering a significant portion of the withholding. Without filing a non-resident tax return, the 25% gross withholding becomes your final Canadian tax with no deductions applied.

Elect Section 216 for Rental Income

Filing a Section 216 election on your non-resident tax return lets you pay graduated Canadian tax rates on net rental income instead of 25% on gross rent. Deducting mortgage interest, property tax, insurance, and management fees on your non-resident rental return typically reduces your effective Canadian tax rate to under 10% — saving thousands compared to the default 25% withholding.

Obtain Section 116 Clearance Certificates

If you sell Canadian real property as a non-resident, your buyer must withhold 25% of the sale price unless you obtain a Section 116 clearance certificate from CRA before closing. Filing for Section 116 on your non-resident tax return limits withholding to 25% of the capital gain only — not the entire sale price — freeing up hundreds of thousands in sale proceeds at closing.

Apply Tax Treaty Reduced Rates

Canada has tax treaties with over 90 countries that reduce the standard 25% non-resident withholding tax on dividends, interest, royalties, and pensions. Your non-resident tax return must claim the correct treaty rate — for example, 15% on dividends under the Canada-US treaty instead of 25%. Applying the treaty rate on your non-resident return saves 10% or more on every payment received.

Recover Over-Withheld Canadian Tax

If your Canadian payer withheld 25% Part XIII tax but the applicable treaty rate or your actual tax on a non-resident tax return is lower, CRA refunds the difference. Many non-residents leave overpaid withholding tax unclaimed for years. Filing your non-resident tax return with accurate NR4 reconciliation is the only way to recover these excess amounts from CRA.

File NR6 to Reduce Monthly Withholding

Submit Form NR6 before the first rental payment of the year so your property manager withholds 25% on estimated net rental income instead of gross rent. Without an approved NR6, your non-resident withholding locks up cash unnecessarily each month. Coordinating NR6 with your annual non-resident tax return keeps funds available for property expenses and mortgage payments throughout the year.

Report All Canadian Income Sources

Your non-resident tax return must include every Canadian income source — rental, pension, RRSP withdrawals, capital gains, dividends, and employment income earned in Canada. Omitting a source triggers CRA matching against NR4 slips, T4A-NR slips, and Section 116 certificates, resulting in reassessment with penalties of 5% plus 1% per month on unreported non-resident income.

Claim Foreign Tax Credits Abroad

Canadian tax paid on your non-resident tax return is generally eligible as a foreign tax credit on your home country return — preventing double taxation. File and assess your non-resident Canadian return before your home country deadline so you have the exact CRA-assessed tax amount to claim. Missing this coordination means paying full tax in both countries on the same income.

File Your Non-Resident Return on Time

Your T1-NR non-resident tax return is due April 30 of the year following the income year, and Section 216 rental returns are due June 30. Late non-resident tax filing triggers a 5% penalty on unpaid tax plus 1% per month for up to 12 months — and for Section 216, CRA denies expense deductions entirely if you miss the deadline, taxing you on gross rental income.
