Saskatchewan 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 Tax Guide for Saskatchewan Landlords: New Mexico Edition

As a Saskatchewan resident owning rental property in New Mexico, you operate at the intersection of three tax jurisdictions: Canada (federal and provincial), the United States (federal), and New Mexico state. Each jurisdiction has different rules, deadlines, and filing requirements. Understanding how these systems interact—and where they conflict—is essential to avoiding penalties, double taxation, and costly mistakes.

This guide walks you through your obligations in plain language, with specific forms, rates, and deadlines you'll need to meet each year.

Why This Combination Matters

The core challenge: When you earn rental income in the US as a Canadian resident, you're subject to tax by both countries on the same income. Additionally, New Mexico imposes state-level tax on non-residents earning income within the state. Without proper planning, you could face:

• Part XIII withholding at 25% on gross rents (Canada Revenue Agency)
• US federal withholding at 30% on gross rents (Internal Revenue Service)
• New Mexico state income tax at 5.9% on net rental income
• Double taxation without claiming a foreign tax credit

The good news: proper filing and elections can reduce or eliminate these withholdings and allow you to claim credits for taxes paid to the US.

Your Obligations to the Canada Revenue Agency (CRA)

File Form T776 (Rental Income)

Every year, you must report your US rental income on Form T776 (Statement of Real Estate Rentals) as part of your Canadian tax return. This is true even if you've already filed with the IRS.

What to report:

• Gross rental income (converted to CAD at the Bank of Canada average annual exchange rate)
• Expenses: property tax, mortgage interest, property management fees, repairs, insurance, utilities, and capital cost allowance (CCA)
• Net rental income (loss)

Currency conversion: Use the Bank of Canada daily average exchange rate for the day you receive each payment, or use the annual average rate for the entire year (permitted simplification). For 2025, the annual average is approximately 1 USD = 1.3978 CAD. Lock in your method and document it.

Avoid Part XIII Withholding with Form NR6

If you do not file Form NR6 (Undertaking—Non-Resident of Canada) with the IRS, your US property manager or rental agent must withhold 25% of gross rents and send it to the CRA. This withholding is non-refundable and applies to the gross amount, not your net income.

To avoid this:

1. File Form NR6 with the IRS (see IRS obligations section below)
2. Provide a copy to your property manager in New Mexico
3. Keep renewal documents current (NR6 is valid for 2 calendar years)

Without this form, you lose 25% immediately—a significant cash flow problem.

Claim a Foreign Tax Credit (Form T2209)

After paying US federal tax, US state tax, and potentially withholding taxes, you can claim a foreign tax credit using Form T2209 to reduce your Canadian tax liability dollar-for-dollar (within limits).

The order matters:

1. Calculate Canadian tax on worldwide income (including US rental income)
2. Subtract the lesser of:
   • The actual US tax paid, or
   • Canadian tax attributable to the US income

You can only claim what you actually paid (or had withheld). Keep all receipts, IRS notices, and payment confirmations.

File Form T1135 (Foreign Property)

If the fair market value of your New Mexico property exceeds CAD $100,000 at any point in the year, you must file Form T1135 (Foreign Property Disclosure Form) with your Canadian tax return.

• This is an informational return only—it doesn't create a tax liability
• Failure to file can result in a $2,500 penalty
• Report the fair market value in CAD (use Bank of Canada rates)

Your Obligations to the Internal Revenue Service (IRS)

Obtain an ITIN (Individual Taxpayer Identification Number)

You cannot file a US tax return or claim a foreign tax credit without an ITIN (Individual Taxpayer Identification Number). This is not your Social Insurance Number (SIN); it's a nine-digit number issued only by the IRS.

To obtain an ITIN:

1. Complete Form W-7 (Application for IRS Individual Taxpayer Identification Number)
2. Attach a certified copy of your passport or birth certificate
3. Mail to the IRS (addresses vary by country; use IRS.gov to find the address for Canada)
4. Processing takes 4–6 weeks; an ITIN is valid indefinitely for tax purposes

You'll need your ITIN for all future US tax filings.

File Form NR6 with the IRS to Stop Withholding

Form NR6 (Undertaking—Non-Resident of Canada) filed with the IRS certifies that you are a non-resident of Canada and that rental income is not subject to Canadian withholding. This prevents the 25% Part XIII withholding.

Where to file:

• US Internal Revenue Service, Philadelphia Service Center, Philadelphia, PA 19255-0732

Timeline: File before the beginning of the tax year (ideally by December 31 of the prior year). Renew every 2 years.

File Form 1040-NR (US Non-Resident Tax Return)

As a non-resident earning US rental income, you must file Form 1040-NR (Nonresident Alien Income Tax Return) with the IRS by June 15 (deadline extended from April 15 for non-residents filing from abroad).

Required with 1040-NR:

• Schedule E (Supplemental Income or Loss) — report rental income and expenses
• Form 1040-NR-EZ (if eligible—simplified form for certain non-residents)

What to report:

• Gross rental income (in USD)
• Deductible expenses (property tax, mortgage interest, repairs, maintenance, management fees, property taxes, insurance, utilities, and depreciation)
• Depreciation is calculated on the building value only (not land) using the Modified Accelerated Cost Recovery System (MACRS), typically a 27.5-year straight-line method for residential property

Make the Section 871(d) Election to Reduce Federal Withholding

By default, the IRS withholds 30% of gross rental income from non-residents. This is devastating—you lose 30% immediately, even though your actual tax liability may be much lower.

Solution: File Form 8288-B (Statement of Withholding on Disposition by Foreign Persons of US Real Property Interests) and Form 8833 (Treaty-Based Return Position Disclosure) to elect under Section 871(d).

Under this election:

• You pay tax on net rental income (after expenses), not gross
• Your effective rate drops dramatically
• You must file Form 1040-NR annually

Example: If you collect $30,000 USD in rents and have $12,000 USD in expenses:

• Without the election: 30% × $30,000 = $9,000 withheld
• With the election: tax on $18,000 net (taxed at your marginal rate, typically 10–12%)

Pay Estimated Taxes

If you expect to owe more than $1,000 in US federal tax after withholdings and credits, you must pay US estimated quarterly taxes using Form 1040-ES.

Due dates: April 15, June 15, September 15, and January 15 (following year).

New Mexico State Tax Obligations

File Form PIT (Personal Income Tax Return)

New Mexico requires non-residents earning income in the state to file a New Mexico Form PIT (Personal Income Tax Return) by April 15 (or June 15 if you file a US extension).

Tax rate: New Mexico taxes non-resident net rental income at 5.9% (2025 rate).

What to report:

• Net rental income from New Mexico property (gross income minus allowable deductions)
• New Mexico allows the same deductions as the IRS (mortgage interest, property tax, repairs, depreciation, etc.)
• Credit for taxes paid to other jurisdictions (if applicable)

Property Tax

New Mexico's average effective property tax rate is 0.8% of assessed value. Property taxes are deductible against both US and Canadian income and are due annually (typically by the first business day of November).
