US and Canada Tax Obligations
US citizens and Canadian residents owning Mexican property have significant reporting obligations to their home country tax authorities. These are not optional. Non-compliance penalties start at $10,000 USD per violation per year and can reach 50% of account value for willful failures.
This guide covers reporting obligations only. Engage a cross-border CPA before purchasing. The cost of proper advice ($2,000-5,000) is small relative to penalties for non-compliance.
All Mexican rental income must be reported on your US federal tax return via Schedule E. You can deduct actual expenses (management fees, maintenance, insurance, depreciation, mortgage interest if applicable). ISR paid to Mexico is creditable against US tax via Form 1116 (Foreign Tax Credit), which typically eliminates double taxation on rental income. This is not optional even if the income is small.
Mexican real estate held directly (in your name or via fideicomiso) is NOT subject to FBAR. However, a Mexican bank account used to receive rent payments or pay expenses IS reportable if it exceeds $10,000 at any point. Most buyers open a Mexican peso account at closing -- this account requires FBAR disclosure.
Real estate held directly is generally NOT a specified foreign financial asset for Form 8938 purposes. However, a Mexican corporation (SA de CV) holding real estate IS reportable. Whether a fideicomiso constitutes a specified foreign financial asset is technically unsettled -- most practitioners disclose it as a precaution. Get written legal advice on this point.
The IRS has not issued definitive guidance on whether a Mexican fideicomiso constitutes a foreign trust for US tax purposes. Some practitioners file Form 3520 as a precaution; others take the position that a fideicomiso is not a trust under US law. This is a genuine area of legal uncertainty -- obtain a written opinion from a qualified cross-border tax attorney.
Sale of Mexican property is a taxable event in the US. The gain is calculated in USD (purchase price in USD vs sale proceeds converted to USD at closing day rate). ISR paid at the Mexican closing is creditable against US capital gains tax via Form 1116. Long-term capital gains rates apply if held more than one year. You cannot defer recognition via a 1031 exchange -- that mechanism applies only to US property.
Canadian residents must file T1135 if the total cost of all specified foreign property exceeds CAD $100,000 at any point during the year. Mexican real estate held directly is specified foreign property. The fideicomiso interest is also reportable. This is one of CRA's most actively enforced disclosure requirements.
Mexican rental income is fully taxable in Canada. Report gross rental income and deduct eligible expenses (management fees, repairs, insurance, property tax). ISR paid to Mexico is creditable against Canadian tax under the Canada-Mexico tax treaty via Form T2209. Keep all Mexican expense receipts.
Sale of Mexican property triggers a capital gains event in Canada. The adjusted cost base and proceeds are calculated in CAD at the exchange rates on acquisition and disposition dates respectively. The 50% inclusion rate applies. ISR withheld at Mexican closing is creditable. Note: peso depreciation since purchase can reduce your CAD gain even if the USD price increased.
