Canada–Mexico Tax Treaty Summary

📌 Scope & Definitions

Article 1 — General Scope

Applies to residents of one or both of Canada and the United Mexican States
Does not restrict exemptions, deductions, or credits available under domestic law or other agreements
Each State retains the right to tax its own residents under domestic law where the Convention does not provide otherwise
The Convention is closely linked to the broader North American economic relationship including CUSMA (formerly NAFTA) and reflects the deep trade and investment ties between the two countries
Mexico's federal structure means federal taxes are primarily covered; state and municipal taxes are generally not covered

Article 2 — Taxes Covered

Canada: income taxes imposed by the Government of Canada under the Income Tax Act
Mexico: income tax (impuesto sobre la renta — ISR) imposed under the Ley del Impuesto sobre la Renta (LISR); business flat tax (impuesto empresarial a tasa única — IETU) where applicable; assets tax (impuesto al activo — IMPAC) where applicable
Note: Mexico's IETU was abolished in 2014 and IMPAC was also eliminated; the treaty applies to the ISR as the primary surviving covered tax and any substantially similar successor taxes
Applies to any substantially similar future taxes enacted by either country
Does not cover Mexican VAT (impuesto al valor agregado — IVA), social security contributions (IMSS/INFONAVIT), payroll tax (impuesto sobre nóminas), special production and services tax (IEPS), or customs duties

Article 3 — General Definitions

Defines: Canada, Mexico, person, company, competent authority, national, international traffic, taxable year
Canada's competent authority: Minister of National Revenue or authorised representative
Mexico's competent authority: Minister of Finance and Public Credit (Secretaría de Hacienda y Crédito Público — SHCP) or authorised representative
Undefined terms carry their respective domestic-law meaning under the law of the State applying the Convention
Mexico's Servicio de Administración Tributaria (SAT) administers federal taxes on behalf of the SHCP

📌 Residence & Permanent Establishment

Article 4 — Residence

A person is a resident if liable to tax by reason of domicile, residence, place of management, or similar criteria
Dual-residency tie-breakers for individuals applied in order: (1) permanent home, (2) centre of vital interests, (3) habitual abode, (4) nationality, (5) mutual agreement
For companies: resident in the State where place of effective management is situated
Dual-resident companies resolved by mutual agreement between competent authorities
Mexico treats an individual as resident if the centre of vital interests is in Mexico; an individual is presumed to have their centre of vital interests in Mexico if more than 50% of total income in a calendar year is from Mexican sources or if Mexico is the principal centre of professional activities
Mexico's deemed residency rule: a Mexican national who changes residency to a tax haven is still treated as a Mexican resident for the tax year of the change and the following 3 years unless they can demonstrate a genuine change of residency
Canadian residents of Mexican origin should carefully analyse their residency status under both Mexican domestic law and treaty tie-breaker rules

Article 5 — Permanent Establishment (PE)

PE = fixed place of business: place of management, branch, office, factory, workshop, mine, oil/gas well, quarry, or other place of extraction of natural resources
Building site, construction, assembly, or installation project = PE if it continues for more than 6 months
Service PE: furnishing of services through employees or other personnel = PE if activities continue for more than 183 days within any 12-month period
Supervisory activities connected to a building site = PE if lasting more than 6 months
Dependent agent with authority to conclude contracts = PE
Agent who habitually maintains a stock of goods and regularly delivers goods on behalf of the enterprise = PE
Preparatory or auxiliary activities do not create a PE
Independent broker or agent acting in the ordinary course of business does not create a PE
Note: the 6-month building site threshold is notably shorter than the 12-month threshold in many of Canada's other modern treaties; reflects Mexico's negotiating position

📌 Business & Property Income

Article 6 — Income from Immovable Property

Income from real property situated in the other State may be taxed in the situs State
Covers agriculture, forestry, direct use, letting, and all other forms of use of immovable property
Applies equally to income from immovable property of an enterprise and from property used for independent personal services
Rights to variable or fixed payments for the working of mineral deposits and other natural resources treated as immovable property
Ships, aircraft, and containers are not treated as immovable property for purposes of this Article
Mexico's special tax regime for rental income from Mexican real property requires careful analysis for Canadian residents receiving Mexican rental income

Article 7 — Business Profits

Taxable only in the residence State unless a PE exists in the other State
If PE exists, the other State may tax profits attributable to the PE on an arm's-length, separate-entity basis
Deductions allowed for executive, general administrative, R&D, and other expenses incurred for the PE regardless of where incurred
No profits attributed to a PE solely from purchasing goods for the enterprise
Mexico's ISR applies at a general corporate rate of 30% to PE profits
Mexico's maquiladora regime: maquiladora companies operating under the IMMEX programme have special tax rules including a safe harbour for transfer pricing; interaction with treaty PE provisions requires specialist analysis
Profits attributed to a PE determined consistently from year to year using the same method unless there is good reason to change

Article 8 — Shipping and Air Transport

Profits from ships or aircraft in international traffic: taxable only in the residence State
Covers transportation of passengers, mail, livestock, and goods; related activities; incidental rental of ships or aircraft
Container profits used in connection with international transport: taxable only in the residence State
Gains from alienation of ships or aircraft used in international traffic: taxable only in the residence State
Special provision: profits of Air Canada and Aeroméxico given reciprocal exemption treatment

Article 9 — Associated Enterprises (Transfer Pricing)

Each State may adjust income where related-party transactions are not at arm's length
Where one State makes an upward adjustment, the other State shall make a corresponding downward adjustment to avoid double taxation
Mexico's transfer pricing rules under the LISR apply in conjunction with this Article; Mexico was one of the first developing countries to adopt comprehensive transfer pricing rules modelled on OECD guidelines
Advance pricing agreements (APAs) available from Mexico's SAT; recommended for significant related-party transactions particularly in the maquiladora sector
Mexico's maquiladora safe harbour (Article 182 LISR) provides a simplified transfer pricing method for maquiladora operations; interaction with treaty provisions requires analysis
Secondary adjustments may be made under Mexican domestic law where appropriate

📌 Passive Income — Withholding Rates

Article 10 — Dividends

Direct investment (beneficial owner is a company holding ≥10% of the voting power): 5%
All other cases (portfolio): 15%
Dividends paid to a pension fund or retirement plan that is a resident of the other State and does not hold more than 10% of the paying company: exempt (0%)
Dividends paid to the Government or central bank of the other State: exempt (0%)
Dividends attributable to a PE in the source State: taxed under Business Profits (Article 7)
Mexico's domestic withholding rate on dividends paid by Mexican companies to non-residents: Mexico abolished its dividend withholding tax in 1999 for dividends paid from the cuenta de utilidad fiscal neta (CUFIN — after-tax earnings account); however dividends paid from other accounts or from profits not subject to corporate tax are subject to a gross-up and additional ISR; treaty rate of 5%/15% applies to the extent a withholding tax is imposed
Note: Mexico reintroduced a 10% dividend withholding tax in 2014 on dividends paid from profits generated from 2014 onwards; the treaty rate of 5% for direct investors and 15% for portfolio investors applies to reduce this domestic rate

Article 11 — Interest

General treaty rate: 10%
Reduced rate of 15% applies to interest paid by financial institutions (banks) — note this is higher than the general rate reflecting Mexico's negotiating position
Fully exempt (0%) if derived and beneficially owned by:
- The Government, a political subdivision, or central bank of the other State
- The Bank of Canada or the Banco de México
- Export Development Canada or Nacional Financiera (NAFIN) or Banco Nacional de Comercio Exterior (Bancomext) or equivalent Mexican development banking institution
- A pension fund or retirement plan that is a resident of the other State
Excess interest arising from a special relationship between payer and recipient taxed under domestic law
Mexico's domestic withholding rate on interest paid to non-residents varies: 4.9% for interest paid to foreign banks on loans registered with the SAT; 10% for bonds listed on recognised stock exchanges; 15% for certain financial leasing; 21% for most other interest; 35% for interest paid to residents of tax havens; treaty provides significant reduction to 10% for most interest

Article 12 — Royalties

General rate: 10%
Covers payments for use of copyright, patent, trademark, design, secret formula, industrial, commercial, or scientific equipment, and know-how
Cultural royalties (literary, dramatic, musical, or artistic works, excluding films and tapes for broadcasting): 10%
Software royalties: 10%
Equipment royalties: 10%
Technical assistance fees that constitute royalties under Mexican domestic law: 10%
Royalties attributable to a PE or fixed base: taxed under Article 7
Mexico's domestic withholding rate on royalties paid to non-residents is generally 25% (reduced for certain categories); treaty provides significant reduction to 10%

📌 Capital Gains

Article 13 — Gains

Gains from alienation of immovable property situated in the other State: taxable in the situs State
Gains from alienation of shares or comparable interests deriving more than 50% of their value directly or indirectly from immovable property situated in the other State: taxable in the situs State
Gains from alienation of business assets forming part of a PE or fixed base: taxable in the State where the PE or fixed base is situated
Gains from alienation of ships or aircraft in international traffic: taxable only in the residence State
Gains from alienation of shares of a Mexican or Canadian company: may be taxed in the source State if the alienator held at least 25% of the company's capital at any time during the 12 months preceding the alienation
All other gains: taxable only in the residence State
Mexico's domestic rules on capital gains by non-residents: non-residents disposing of Mexican shares are subject to a 25% withholding on gross proceeds or 35% on net gain (with election); treaty provides relief for qualifying Canadian residents
Mexico's requirement for a legal representative and tax authority notification for share disposals by non-residents must be complied with regardless of treaty relief

📌 Branch Profits Tax

Article 14 — Branch Tax

Canada may impose a branch profits tax on after-tax profits of Mexican enterprises attributable to a Canadian PE
Treaty rate cap on branch profits tax: 5% where the Mexican parent holds ≥10% of the Canadian entity; 15% in all other cases
Mirrors the dividend withholding rates to ensure equal treatment of branch and subsidiary operations
Mexico imposes a similar branch profits tax equivalent on profits remitted by a PE to its foreign head office; treaty rate cap applies

📌 Personal Services

Article 15 — Independent Personal Services

Taxable in the residence State
Also taxable in the source State if the individual has a fixed base regularly available in that State, or is present for more than 183 days in any 12-month period
Income attributable to the fixed base or to the period of presence may be taxed in the source State
Mexico's domestic withholding rules for non-resident independent service providers require careful compliance; treaty relief obtained through SAT procedures

Article 16 — Dependent Personal Services (Employment Income)

Taxable only in the residence State unless work is performed in the other State
Exemption from source-State tax if:
- Individual is present for ≤183 days in any 12-month period, AND
- Remuneration is paid by an employer who is not a resident of the source State, AND
- Remuneration is not borne by a PE or fixed base in the source State
Special rules apply to employees of ships and aircraft in international traffic: taxable only in the residence State of the employer
Mexico's ISR withholding on employment income requires Mexican employers to withhold tax at progressive rates up to 35%; treaty relief obtained through SAT exemption or refund procedures
Mexico's statutory profit sharing (participación de los trabajadores en las utilidades — PTU): employers must distribute 10% of taxable profits to employees; PTU is not covered by the treaty but affects the overall cost of employing staff in Mexico

Article 17 — Directors' Fees

Directors' fees and similar payments derived by a resident of one State from a company resident in the other State may be taxed in the source State
Applies to members of a consejo de administración (board of directors) of a Mexican company

Mexico's domestic withholding rate on directors' fees paid to non-residents is generally 25%; treaty relief available

Article 18 — Entertainers and Athletes

Income derived by entertainers (theatre, film, radio, TV, music) and athletes from activities performed in the other State may be taxed in the State of performance
Applies regardless of Articles 15 and 16
Exemption if the visit is substantially supported by public funds of the residence State or a political subdivision thereof
Anti-avoidance provision: applies even where income is channelled through a third-party entity rather than paid directly to the entertainer or athlete
Mexico's significant entertainment and sports industry makes this provision of practical importance for visiting Canadian athletes and performers

📌 Government Service, Pensions & Education

Article 19 — Government Service

Salaries paid by a State or its political subdivision to an individual for services rendered to that State: taxable only in the paying State
Exception: taxable only in the other State if the individual is a resident and national of that other State and not a national of the paying State
Government pensions follow the same rules as salary payments above
Special provisions apply to employees of the Mexican Embassy and consulates in Canada and the Canadian Embassy and consulates in Mexico

Article 20 — Pensions and Annuities

Private pensions and annuities derived by a resident of one State from sources in the other State: taxable only in the residence State
Social security benefits paid by one State to a resident of the other State: taxable only in the paying State
Mexico's IMSS (Instituto Mexicano del Seguro Social) pension and ISSSTE (Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado) government workers pension treated as social security for treaty purposes
Mexico's AFORE (Administradoras de Fondos para el Retiro) individual retirement accounts: contributions made by employers and employees to AFOREs accumulate tax-free; withdrawals by Canadian residents generally treated as private pension income taxable only in Canada
Canada Pension Plan (CPP) and Old Age Security (OAS) payments to Mexican residents: taxable only in Canada
Alimony and maintenance payments: taxable only in the recipient's State of residence

The 2-year exemption period begins from the date of first arrival in the host State for the relevant purpose

📌 Other Income

Article 23 — Other Income

Income of a resident of one State not dealt with elsewhere in the Convention: taxable only in the residence State
Exception: if the income arises in the other State, that State may also tax it under its domestic law
Income attributable to a PE or fixed base: taxed under Article 7 or Article 15

📌 Limitation on Benefits

Article 24 — Limitation on Benefits

Treaty benefits may be denied where the principal purpose of an arrangement was to obtain treaty benefits
Principal purpose test (PPT): benefits denied where one of the principal purposes of an arrangement was to obtain treaty benefits
Competent authorities may deny benefits where a transaction was designed to abuse the Convention
Conduit arrangements: benefits denied where the structure is used to channel payments through an intermediary to non-qualifying third-country residents
Discretionary relief available from competent authorities where benefits are otherwise denied
Both Canada's GAAR and Mexico's anti-abuse provisions under the CFF (Código Fiscal de la Federación) apply in addition to treaty anti-abuse provisions
Mexico's aggressive tax planning reporting obligations (DPAC — Declaración de Operaciones Relevantes and mandatory disclosure rules for reportable schemes) require disclosure of certain treaty-based structures

📌 Relief from Double Taxation

Article 25 — Relief from Double Taxation

Canada: provides a foreign tax credit for Mexican taxes paid on income arising in Mexico including ISR; credit limited to the proportion of Canadian tax attributable to that income
Mexico: provides a credit for Canadian taxes paid on income arising in Canada; credit method generally applies under Mexican domestic law for foreign taxes paid
Exemption with progression: exempted income may still be taken into account in determining the applicable tax rate on remaining income
Mexico's acreditamiento (tax credit) mechanism under the LISR allows Mexican residents to credit foreign taxes paid on foreign-source income; interaction with treaty double tax relief requires analysis
Special rules ensure Canadian residents receiving Mexican-source income subject to multiple Mexican taxes receive appropriate credit relief

📌 Non-Discrimination & Procedure

Article 26 — Non-Discrimination

Nationals of one State shall not be subjected to more burdensome taxation in the other State than nationals of that other State in the same circumstances

Residents may present cases to the competent authority of their State within 3 years of first notification of taxation not in accordance with the Convention
Competent authorities shall endeavour to resolve disputes by mutual agreement
Competent authorities may communicate directly, including through a joint commission
MAP cases involving Mexico can be complex given the SAT's administrative capacity and the complexity of Mexican domestic tax law

Convention remains in force indefinitely
Either State may terminate by giving written notice through diplomatic channels on or before 30 June of any calendar year; Convention ceases to have effect from 1 January of the following year

📌 Practical Considerations Unique to Canada–Mexico

CUSMA / NAFTA Context: The Canada–Mexico tax treaty operates alongside CUSMA (Canada-United States-Mexico Agreement, formerly NAFTA); the broader North American economic framework creates significant cross-border investment and trade flows that generate treaty-related tax issues; both agreements should be considered together for cross-border business planning
Maquiladora Sector: Canada is a significant investor in Mexico's maquiladora manufacturing sector; maquiladora companies operating under the IMMEX programme have special transfer pricing safe harbour rules under Article 182 LISR; the interaction between the maquiladora safe harbour, treaty PE provisions, and Canadian foreign tax credit rules requires specialist advice
Mexican Interest Withholding Complexity: Mexico's domestic withholding tax rates on interest vary enormously (4.9% to 35%) depending on the nature of the interest, the type of lender, and whether the loan is registered with the SAT; treaty rate of 10% provides certainty but domestic rates may sometimes be lower; careful analysis required
Dividend Withholding Reintroduction: Mexico reintroduced a 10% dividend withholding tax in 2014 on dividends from profits generated from 2014 onwards; the treaty's 5% rate for direct investors provides significant relief; CUFIN management (tracking after-tax earnings) remains important to minimise Mexican dividend tax
Mexican Mandatory Disclosure: Mexico's aggressive mandatory disclosure rules (DPAC and Anexo 25 reporting) require disclosure of certain international arrangements including treaty-based structures; Canadian advisors and multinational groups with Mexico operations should be aware of these obligations
AFORE Pension Accounts: Mexican workers' AFORE individual retirement accounts accumulate significant balances; Canadians who worked in Mexico and have AFORE balances should seek advice on the Canadian tax treatment of eventual AFORE withdrawals; treaty pension provisions generally result in Canadian taxation of AFORE distributions received by Canadian residents
Real Estate Investment: Mexico's growing real estate market (particularly in resort areas such as Los Cabos, Puerto Vallarta, Riviera Maya, and Mexico City) attracts significant Canadian investment; non-residents disposing of Mexican real estate are subject to complex Mexican tax rules; notarial withholding at the time of sale and annual ISR returns are required; treaty capital gains provisions provide relief for qualifying Canadian residents
Mexican Anti-Tax Haven Rules: Mexico has extensive anti-tax haven legislation; payments to residents of countries on Mexico's tax haven list may be subject to higher withholding rates; Canada is not on Mexico's tax haven list so these rules do not affect Canada-Mexico flows directly, but structures involving third countries must be carefully reviewed
MLI: Both Canada and Mexico have ratified the OECD MLI; given the treaty was signed in 2006, MLI modifications including PPT and PE provisions are particularly important to review; both countries' MLI positions should be consulted for the current effective treaty text
Social Security Agreement: A bilateral social security agreement between Canada and Mexico exists separately from the income tax treaty; this agreement coordinates CPP and Mexican IMSS/ISSSTE contributions for individuals who have worked in both countries; particularly relevant for Canadians on secondment to Mexico or Mexican nationals working in Canada
Canadian Retirees in Mexico: Mexico has become an increasingly popular retirement destination for Canadians particularly in the Yucatán Peninsula, Lake Chapala region, and Pacific Coast resort areas; Canadian retirees resident in Mexico must establish genuine Mexican tax residency; CPP, OAS, and private pension income is generally taxable only in Canada under the treaty; Mexican residents must also comply with Mexican tax filing obligations
Transfer Pricing and Maquiladoras: Canada is a significant investor in Mexican manufacturing through the maquiladora programme; the SAT actively enforces transfer pricing rules for maquiladora operations; APA agreements with the SAT provide certainty and are strongly recommended for significant maquiladora arrangements involving Canadian parent companies
Digital Economy: Both Canada and Mexico have been addressing digital economy taxation; Mexico introduced a digital services tax (DST) in 2020 requiring foreign digital platforms to register with the SAT and withhold ISR and IVA on payments to Mexican content providers; Canadian digital businesses with Mexican users should assess compliance obligations under Mexican domestic law and treaty implications

This summary is for general reference only. Always consult the full Convention text, the associated Protocol, and any OECD Multilateral Instrument (MLI) modifications for authoritative guidance. Rates shown are maximum treaty rates; lower domestic rates take precedence. The interaction between Mexico's complex domestic withholding tax system, mandatory disclosure rules, maquiladora regime, and Canadian foreign tax credit rules makes Canada–Mexico tax planning particularly detailed; professional advice from specialists in both Canadian and Mexican tax law is strongly recommended for any cross-border planning or compliance matters.
