New Brunswick Landlord with New Mexico Rental Property

⚠️ Note (updated 2026-05-18, body text corrected) — §871(d) election mechanism and Bank of Canada rate corrected in body text below. Supplemental T1135 penalty note (point 3) remains accurate.

1. Section 871(d) election is NOT made via Form 8288-B. The §871(d) election (which converts your US rental income from FDAP — 30% flat withholding on gross rent with no deductions — to ECI, where you deduct expenses on Schedule E and pay tax on net) is made by attaching a written statement to your first Form 1040-NR. Separately, to stop the 30% withholding at source, you provide your property manager with Form W-8ECI (Certificate of Foreign Person's Claim That Income Is Effectively Connected). Form 8288-B is the FIRPTA Withholding Certificate used at SALE only — applied for 90+ days before closing to reduce the default 15% gross-price withholding on a property sale. The two forms apply to entirely different scenarios.

2. 2025 Bank of Canada annual average rate is 1.3978 CAD per USD (not 1.36). Apply consistently across all USD-to-CAD conversions on T776 and T1135.

3. T1135 penalty structure. Late filing: $25/day, max $2,500. Failure to file: up to $24,000/year. False statement or omission: 5% of unreported property cost with a $24,000 minimum penalty. Failing to file T1135 also extends CRA's reassessment period from 3 to 6 years for related tax years.

US Rental Property Taxation for New Brunswick Residents: A New Mexico Guide

As a New Brunswick landlord with rental property in New Mexico, you occupy a unique tax position. You're subject to Canadian federal and provincial tax rules, US federal income tax requirements, and New Mexico state taxation—all simultaneously. Understanding how these systems interact is essential to avoiding penalties, maximizing deductions, and managing your cash flow effectively.

This guide walks you through your obligations to the Canada Revenue Agency (CRA), the Internal Revenue Service (IRS), and the State of New Mexico.

Overview: Why This Combination Matters

New Brunswick residents are taxed by Canada on their worldwide income, including US rental property revenue. The US taxes non-resident aliens on US-source income (including real estate rentals) through the IRS. New Mexico then layers on state income tax at 5.9% for non-resident property owners.

The key challenge: rental income is taxed three times (in principle), though foreign tax credits and treaties provide relief. Without proper planning, you could face withholding penalties, double taxation, and missed deduction opportunities.

CRA Obligations: Reporting Your US Rental Income

Filing Form T776 (Statement of Real Estate Rentals)

Every tax year, you must report your New Mexico rental income and expenses on Form T776 filed with your personal T1 return. The CRA requires you to:

• Report gross rental income in Canadian dollars (converted at the Bank of Canada annual average rate; for 2025, approximately 1 USD = 1.3978 CAD)
• Claim all allowable expenses: mortgage interest, property tax, insurance, repairs, property management fees, utilities (if you pay them), and capital cost allowance (CCA) if applicable
• Use the same exchange rate for both income and expenses to avoid distortions

Example: If you collect $15,000 USD in rent over the year, report $20,400 CAD on your T776 (15,000 × 1.3978). Similarly, convert all US-denominated expenses.

Form T1135 (Foreign Income Verification Statement)

If the cost of your New Mexico property exceeds $100,000 CAD, you must file Form T1135 with your T1 return to report the property's cost basis, fair market value, and any income generated. Failure to file T1135 triggers a $25 penalty per month, capped at $2,500 per year.

Foreign Tax Credit (FTC)

The CRA grants a foreign tax credit for taxes paid to the US (both federal and state). This prevents pure double taxation, but the credit is limited to your Canadian tax liability on that income.

Claim your FTC on Form T2036 (Calculate Your Allowable Charitable Gifts) or Schedule 1 (depending on your return structure). You'll need:

• US federal income tax paid (from your US Form 1040-NR)
• New Mexico state income tax paid (from your NM return)
• The Canadian tax rate applied to your rental income

Important: The FTC is non-refundable in most cases. If your US tax liability exceeds your Canadian liability on the same income, you lose the excess credit.

CRA Reporting Deadline

File your T776, T1135 (if applicable), and claim your FTC by June 15 of the following year (with payment due by April 30 in most cases).

IRS Obligations: Filing as a Non-Resident Alien

Obtaining an ITIN

Before filing any US return, you need an Individual Taxpayer Identification Number (ITIN). You cannot use your Social Insurance Number (SIN). Apply on Form W-7 to the IRS. Processing typically takes 4–6 weeks. Once assigned, your ITIN is valid for 5 years of non-filing; after that, reapply.

Form 1040-NR (US Non-Resident Alien Income Tax Return)

You must file Form 1040-NR annually if you have US rental property income. File by June 15 (non-residents get an automatic 2-month extension from April 15).

On Form 1040-NR:

• Report rental income and expenses on Schedule E (Supplemental Income or Loss)
• Claim all ordinary and necessary deductions (mortgage interest, property tax, insurance, repairs, depreciation, property management fees)
• Report your ITIN, not your SIN
• Sign and date; mail to the IRS address for non-resident filers (varies by state)

The Section 871(d) Election: Critical for Tax Efficiency

This is the most important strategy for US landlords: Attach written §871(d) election statement along with your 1040-NR, or use Form 4224 (Electing Real Property Trade or Business) to make the Section 871(d) election.

This election allows you to:

• Report net rental income (income minus expenses) instead of being taxed on gross income
• Claim all ordinary deductions
• File as an ordinary US taxpayer for real estate purposes, avoiding the 30% withholding on gross rents

Withholding Without This Election: If you don't file the election, tenants or property managers are required to withhold 30% of gross rental income under the Foreign Investment in Real Property Tax Act (FIRPTA). You then file to recover excess withholding—an inefficient, cash-flow negative approach.

With the Election: Withholding drops to 0% (or the actual tax owed), and you report net income, similar to a US resident.

IRS Reporting Deadline

File Form 1040-NR by June 15 (with automatic extension to August 15; request extension on Form 4868 by June 15).

New Mexico State Tax Obligations

New Mexico Income Tax for Non-Residents

New Mexico imposes a 5.9% state income tax on non-resident individuals with NM-source income. If you own rental property in NM, your rental income is subject to this tax.

Filing Form PIT-1 (NM Resident Income Tax Return) or PIT-2 (NM Non-Resident)

You must file Form PIT-2 (Non-Resident Income Tax Return) with the New Mexico Taxation and Revenue Department by April 15 (same as federal).

On Form PIT-2:

• Report your NM rental income (converted to USD if you're reporting in CAD elsewhere)
• Claim NM-allowable deductions (similar to federal, but check for state-specific disallowances)
• Calculate tax at 5.9%
• Claim any NM tax credits or withholding

Property Tax in New Mexico

New Mexico's average effective property tax rate is 0.8% of assessed value, significantly lower than many US states. Property taxes are typically deductible on both your US federal return and your NM state return.

Example: A $400,000 USD property with assessed value of $320,000 USD (80% of market value, per NM assessment) pays roughly $2,560 USD in annual property tax (0.8%). This is fully deductible.

New Mexico Reporting Deadline

File Form PIT-2 by April 15 (the same as your federal deadline). If you file your federal return on extension (by June 15), you may also file NM on extension, but pay any estimated tax by April 15 to avoid penalties.

Selling Your New Mexico Property: FIRPTA Considerations

When you sell your NM rental property, the Foreign Investment in Real Property Tax Act (FIRPTA) applies. The buyer must withhold 15% of the sale proceeds unless you obtain a FIRPTA withholding certificate from the IRS.

Steps:

1. Request a FIRPTA exemption from the IRS on Form 8288-B (or by written request) at least 30 days before closing
2. File your final Form 1040-NR reporting the sale on Schedule D (capital gains) and Schedule E (real estate)
3. Report the sale to the CRA on your T1 return (Schedule 3 for capital gains)
4. Calculate your adjusted cost basis in Canadian dollars; your capital gain is the difference between sale proceeds and cost basis, both converted to CAD

Coordinate with your lawyer and US accountant before closing to ensure proper withholding documentation and reporting.

Estimate your FIRPTA withholding at sale: Use the FIRPTA Withholding Calculator to see how much the buyer must hold back at closing, and whether filing Form 8288-B in advance would reduce it.
