Leaving Canada for Mexico: What's the Tax Picture?

The same departure tax that applies to any Canadian emigrant applies when you leave for Mexico: CRA deems you to have sold every capital asset at fair market value on the day you go. The distinctive feature of the Mexico corridor is Article 13(8) of the Canada-Mexico tax treaty (signed September 12, 2006): it gives you the right to elect a cost-base step-up, so Mexico treats your assets as if you bought them at FMV on the day you arrived. That prevents the same gain from being taxed twice. Among the corridors covered in this series, only the Australia treaty offers the same protection; the UK and Portugal treaties do not. The three decisions that shape your transition: making a clean break from Canadian residency, what to do with your RRSP and TFSA, and whether Mexico’s residency rules actually apply to you.

Who is this page for, exactly?

Canadian tax residents moving to Mexico permanently or long-term: a temporary resident visa (residente temporal), a permanent resident visa (residente permanente), or retirement on a temporary-resident basis. Not for short vacation stays, snowbird winters, or Mexicans moving to Canada. If you are leaving Canada for the US, start with the leaving-Canada tax checklist. If you are heading for the UK, the pension treatment is more favorable (zero withholding): leaving Canada for the UK. For Portugal, the pension treaty includes a $12,000 exemption: leaving Canada for Portugal.

The decision map: what happens, in what order?

One table covering both sides of the move. The full Canadian-departure process is in the leaving-Canada tax checklist; this is the Mexico-corridor version.

Step	What happens	Deadline or trigger	Form(s)
1. Sever Canadian residential ties	Sell or vacate your home, cancel provincial health, close the ties CRA weighs	Months before the move	Document everything
2. Pick your departure date and keep proof	The latest of: the day you leave, the day your family leaves, or the day you become a Mexican fiscal resident	Moving day	One-way tickets, visa activation, Mexican lease or deed
3. Value everything you own at FMV on departure day	The deemed disposition inventory for the departure tax	Departure date	T1161 (if reportable property exceeds $25,000), T1243
4. File your final Canadian return	Worldwide income up to the departure date, plus the deemed gains	April 30 following departure (June 15 if self-employed)	T1 with departure date, T1161, T1243
5. Register with Mexico’s SAT	Get an RFC (Registro Federal de Contribuyentes) as a fiscal resident	On or shortly after arrival	RFC registration at SAT office or online
6. Set up Part XIII withholding on Canadian income	Payers switch to non-resident withholding; file NR301 for treaty rates	After departure confirmed	NR301 (treaty eligibility declaration)
7. Decide on RRSP, TFSA, and rental property	Keep the RRSP (15% withholding on periodic payments), collapse the TFSA (Mexico does not recognize it), NR6 if renting out Canadian property	Before or immediately after departure	NR6 (rental), Section 216 return annually
8. File your first Mexican annual return	Worldwide income from the date you become a Mexican fiscal resident	April 30 following the end of the calendar tax year	Declaracion anual

What triggers departure tax when you leave for Mexico?

Section 128.1 of the Income Tax Act deems you to have disposed of every capital asset at fair market value on the day you stop being a Canadian resident. Investments, rental properties (subject to the principal residence exemption), private corporation shares, everything. The gain is reported on your final Canadian return at your marginal rate. The mechanics are identical regardless of destination: T1161 if reportable property exceeds $25,000, T1243 for the deemed dispositions, both filed with the final T1.

Where the Mexico corridor differs from the UK and Portugal is what happens on arrival. Article 13(8) of the treaty gives you an election: you can choose to be treated by Mexico “as if the individual had, immediately before becoming a resident of that State, sold and repurchased the property for an amount equal to its fair market value at that time.” That is a treaty step-up. Mexico only taxes the growth that accrues after you arrive, and Canada only taxes the growth to the departure date. The two countries cleanly split the gain at the departure line. This is the same structure as Article 13(6) of the Australia treaty.

Article 13(6) of the Mexico treaty says gains on most property (other than real property, PE business assets, shares deriving value principally from real property, and 25%+ shareholdings) are “taxable only in the Contracting State of which the alienator is a resident.” Article 13(7) preserves the departure country’s right to tax if the individual was resident at any time during the six years immediately preceding the alienation (note: six years in the Mexico treaty, versus five in the UK and Portugal treaties). Since Canada’s departure tax deems the disposition to occur while you are still a Canadian resident, this confirms Canada’s right to apply the deemed disposition.

For the departure mechanics themselves, see what a deemed disposition is and the PRE on departure.

How does Mexico decide you’re a fiscal resident?

Mexico’s fiscal residency rules live in Article 9 of the Federal Tax Code (Codigo Fiscal de la Federacion, or CFF). They do not rely on a simple day count. The primary test is the permanent home test: if you establish a home (casa habitacion) in Mexico and do not maintain a home in another country, you are a Mexican fiscal resident from the moment that home exists.

If you keep homes in both Mexico and Canada, the centre of vital interests test applies. Mexico considers you a fiscal resident if more than 50% of your total income in the calendar year comes from Mexican sources, or if your principal centre of professional activities is in Mexico. The 183-day presence test is a secondary factor, not the primary one.

If both countries claim you as a resident, the treaty tie-breaker in Article 4(2) follows the full OECD model with four steps: permanent home, centre of vital interests, habitual abode, and nationality. Once the tie-breaker assigns you to Mexico, section 250(5) of the Canadian ITA deems you non-resident in Canada. For more on the Canadian-side analysis, see am I still a Canadian tax resident.

One practical note: Mexico’s tax authority (SAT) has been increasing enforcement of fiscal residency rules for foreign nationals holding temporary or permanent resident visas. Data sharing between SAT and Mexico’s immigration institute (INM) means long-term visa holders who never registered for an RFC may face inquiries. If you plan to live in Mexico as a fiscal resident, register with SAT and file from the start.

What happens to your RRSP and TFSA in Mexico?

Neither account triggers the departure tax. The RRSP continues to grow tax-deferred inside Canada, and you keep it open. As a non-resident, RRSP and RRIF withdrawals attract Part XIII withholding at 25% by default under section 212(1)(h), reduced to 15% for periodic payments under Article 17(2) of the treaty. Lump-sum withdrawals are not periodic, so the full 25% applies unless you elect under Section 217 to file a Canadian return and be taxed at graduated rates.

Mexico also taxes RRSP withdrawals as part of your worldwide income at your marginal ISR rate (up to 35%), with a credit for the Canadian withholding. The planning consequence is the same as in the Australia corridor: draw down the RRSP over multiple years in periodic installments to stay within the 15% treaty cap, and model the Section 217 election each year to see if graduated rates produce less.

The TFSA is the same problem as in every non-US corridor. Mexico does not recognize the TFSA as a tax-sheltered vehicle. Investment income and gains inside it are taxable in Mexico as they accrue. The CRA stops allowing contributions once you are non-resident and penalizes any made while non-resident at 1% per month. Collapse it before or shortly after departure. For more on Part XIII withholding mechanics, the linked guide covers the rates by income type. For RRSP mechanics after leaving, see RRSP for non-residents after leaving Canada.

How are Canadian pensions taxed in Mexico?

Canadian pension income paid to a Mexican fiscal resident (CPP, OAS, employer pensions, periodic RRSP/RRIF) is subject to Canadian Part XIII withholding capped at 15% under Article 17(2) of the treaty. The lesser-of test compares 15% of the gross amount with the graduated rate you would have paid as a Canadian resident, so for small pension amounts the effective withholding can be below 15%. Mexico includes the pension in your worldwide income and taxes it at your marginal ISR rate, giving a foreign tax credit for the Canadian withholding. You pay the higher of the two countries’ effective rates, not both stacked.

OAS portability applies: Service Canada pays OAS to Mexican residents. The recovery tax (the “clawback” under ITA 180.2) applies if your worldwide net income exceeds the threshold ($93,454 for 2025, indexed annually), whether you live in Canada or not.

Canada and Mexico have a social security agreement (in force since May 1, 1996) that provides full totalization: Mexican contribution periods count toward CPP eligibility, and Mexican residence periods after age 18 count toward OAS eligibility. If you do not have 20 years of Canadian residence for full OAS portability, Mexican residence years can fill the gap. The agreement also coordinates coverage to prevent dual CPP/IMSS contributions for temporary workers.

Does Mexico tax worldwide gains from day one?

Yes, once you are a Mexican fiscal resident, Mexico taxes your worldwide income, including capital gains on assets held anywhere. The step-up election under Article 13(8) of the treaty rebases your assets at FMV on arrival, so Mexico only taxes the growth after you move. Without the election, Mexico would compute gains from your original acquisition cost, potentially overlapping with what Canada already taxed at departure.

For listed securities, Mexico applies a flat 10% ISR rate on capital gains. For other assets, gains are included in your general income and taxed at progressive rates up to 35%. Mexico also adjusts the acquisition cost for inflation using published INPC (National Consumer Price Index) factors, which can reduce the taxable gain on assets held for multiple years.

What does this cost, honestly?

The departure tax hits at your marginal rate on gains deemed realized. Zero unrealized gains means zero departure tax. The compliance cost sits on top: a final Canadian return with T1161 and T1243, plus your first Mexican annual return (declaracion anual) with worldwide income, the step-up election, and foreign tax credits. Mexico’s tax year is the calendar year and the filing deadline is April 30, matching Canada’s, which simplifies the transition-year timeline.

The order of operations, condensed?

The sequence mirrors any Canadian departure, with Mexico-specific items slotted in. The full version is in the leaving-Canada tax checklist; here is the short form for the Mexico corridor.

1. Months before: inventory residential ties, plan how each one ends, decide on the home (sell, rent with NR6, or keep vacant).
2. Weeks before: collapse the TFSA, notify CPP/OAS of the address change, cancel provincial health, organize records of every asset’s adjusted cost base (you will need these for the step-up election).
3. Departure day: note the date, keep proof (one-way ticket, visa activation, Mexican lease or property deed).
4. Arrival in Mexico: register with SAT for an RFC, open a Mexican bank account, register for IMSS if employed.
5. Notify Canadian payers: NR301 declaration to apply treaty withholding rates on pension and RRSP income.
6. April 30 following departure: file the final Canadian T1 with T1161 and T1243.
7. April 30 after the first Mexican tax year ends (December 31): file your first Mexican annual return (declaracion anual) with worldwide income, the Article 13(8) step-up election, and foreign tax credits.
8. Ongoing: periodic RRSP/RRIF withdrawals with 15% treaty-rate withholding, annual Section 217 election decision, Mexican annual return each year.
