1. Canadian Tax Obligations
A. Departure from Canada – Deemed Disposition
When you leave Canada and sever tax ties:
- You are deemed to have disposed of most of your property at fair market value (FMV) and reacquired it immediately, which may trigger capital gains tax.
- Excluded from this deemed disposition are:
- Canadian real estate
- RRSPs, RRIFs, TFSAs (though TFSA growth is no longer tax-sheltered abroad)
- Pension plans
- Certain business assets
B. Departure Tax Return (Final Return as Resident)
You must:
- File a final tax return as a resident for the year you leave.
- Report worldwide income earned up to your departure date.
- Fill out Form T1243 (Deemed Disposition) and T1161 (List of properties over $25,000).
C. Non-Resident Status
Once you become a non-resident of Canada:
- You're only taxed in Canada on Canadian-source income, such as:
- Rental income from Canadian property (subject to non-resident withholding tax)
- Canadian pensions (CPP, OAS, RRSP/RRIF withdrawals)
- Certain capital gains on Canadian real estate
D. Non-Resident Withholding Tax
- Generally 25% withholding on Canadian-source income.
- Can be reduced under the Canada–Mexico Tax Treaty to the following:
- 15% on CPP, OAS, RRIF, LIF, RPP, and dividend payments.
- Most Canadian interest earned by a Mexican resident is not subject to withholding tax in Canada.
- Lump sum withdrawals from an RRSP or RRIF are subject to 25% withholding.
- Generally there are no withholding taxes on Canadian capital gains.
2. Mexican Tax Obligations
A. Becoming a Mexican Tax Resident
You are generally considered a Mexican tax resident if:
- Mexico is your center of vital interests, meaning:
- Your main home is in Mexico, or
- More than 50% of your income is from Mexican sources, or
- Your spouse/dependent children reside in Mexico
Note: Mexico does not have a formal departure tax.
B. Worldwide Income
As a Mexican tax resident:
- You must report and pay tax on your worldwide income, including:
- Investment income
- Employment or business income
- Pensions and foreign income
C. Foreign Asset Reporting
You must:
- Report foreign bank accounts, investments, and trusts on the annual Mexican tax return.
- Failure to do so may result in penalties.
D. Foreign Tax Credits
- Mexico allows for foreign tax credits, which may help avoid double taxation on income also taxed in Canada.
- The Canada–Mexico Tax Treaty coordinates this and prevents double taxation.
