Form W-7 for Canadian Landlords in Missouri

What Is Form W-7?

Form W-7, Application for IRS Individual Taxpayer Identification Number (ITIN), is the official IRS document that allows non-US citizens without a Social Security Number (SSN) to obtain a unique nine-digit taxpayer identification number. For Canadian landlords, this ITIN becomes your US tax identifier for filing Form 1040-NR (US Non-Resident Alien Income Tax Return) and managing FIRPTA (Foreign Investment in Real Property Tax Act) withholding obligations.

An ITIN is not a work authorization document—it is strictly for tax reporting purposes. The number itself resembles an SSN (9 digits in the format 9XX-XX-XXXX) but is issued only to foreign nationals required to file US tax returns.

How Form W-7 Applies to Canadian Landlords in Missouri

If you own rental property in Missouri, you are considered a non-resident alien for US federal tax purposes (unless you meet specific presence tests under the Canada-US Tax Treaty). Missouri imposes state income tax on rental income at a rate of 4.7% on net rental income, plus you face federal taxation on the same income.

Federal Taxation

You must file Form 1040-NR (Non-Resident Alien Return) to report:

• Gross rental revenue from Missouri property
• Deductible expenses (mortgage interest, property taxes, insurance, repairs, depreciation)
• Net rental income subject to US federal tax (ranging from 10% to 37% depending on income level)

Missouri State Taxation

Missouri requires non-residents who earn income from Missouri sources to file Form MO-1040(NR) (Missouri Non-Resident Income Tax Return). Your Missouri rental income is taxed at 4.7%, with allowable deductions similar to federal treatment. Missouri property tax on residential rental property averages 1.01% of assessed value annually.

FIRPTA Obligations

If you plan to sell the Missouri property, the buyer's agent or attorney must withhold 15% of the gross sale price under FIRPTA rules (26 U.S.C. § 1445). To report the sale and potentially recover overwitheld amounts, you need an ITIN. Without one, you cannot file the required Form 8288-B (FIRPTA return).

Canada-US Tax Treaty Considerations

Under Article IV of the Canada-US Tax Treaty, you are a Canadian resident for purposes of the treaty. However, you remain liable for US tax on US-source income (rental income from Missouri property). The treaty provides a foreign tax credit mechanism: when you file your Canadian T1 return, you can claim a non-resident portion of Canadian tax paid as a foreign tax credit against your US tax owing, reducing double taxation.

Who Files Form W-7?

You must file Form W-7 if you are:

• A Canadian citizen or resident without a US SSN
• Required to file a US tax return (1040-NR) due to Missouri rental income
• Required to provide an ITIN for FIRPTA withholding or sale reporting
• Unable to obtain an SSN (which is generally reserved for those with work authorization)

Timeline for filing: Apply for the ITIN before or concurrently with your first 1040-NR filing. If you are selling property, apply immediately so FIRPTA withholding agents have the number before closing.

Step-by-Step Instructions for Completing Form W-7

Step 1: Gather Required Documentation

Prepare the following:

• Valid passport (Canadian passport is acceptable primary identification)
• Proof of tax residency in Canada (copy of most recent Canadian T1 return or CRA Notice of Assessment)
• Form W-7 (available at irs.gov)
• Your mailing address in Canada

Do not submit original documents. The IRS requires certified copies or photocopies of documents originating outside the US.

Step 2: Complete Form W-7 Accurately

Line 1(a): Enter your legal name exactly as it appears on your passport.

Line 1(b): Enter your date of birth (MM/DD/YYYY format).

Line 1(c): Citizenship: Select "Canada."

Line 2: Select the reason you need an ITIN. For Missouri rental property, mark "Other (specify)" and write "Form 1040-NR filer—non-resident alien with US rental property income." If applicable, also note FIRPTA requirement.

Line 3: Enter your country of residence (Canada).

Line 4: Mailing address: Provide your Canadian mailing address.

Line 5: Telephone (optional): Include a Canada-based number if you have one.

Line 6: Country of residence (should mirror Line 3).

Step 3: Submit Application

Option A: Mail submission (most common for international applicants) Send Form W-7 with supporting documents to:

Internal Revenue Service
ITIN Operation
P.O. Box 149342
Austin, TX 78714-9342
USA

Option B: In-person submission If you travel to the US, apply at an authorized IRS Acceptance Agent location. ITIN compliance centers exist in major cities, though availability for international applicants may be limited.

Processing time: Expect 15–21 days for mailed applications, though international submissions may take up to 6 weeks due to document verification.

Step 4: Await IRS Confirmation

The IRS will mail your ITIN to your Canadian address. Once received, use it on all US tax forms: 1040-NR, Schedule E (rental income), Form 8288-B (if selling property), and Missouri Form MO-1040(NR).

Missouri-Specific Considerations

Nexus and State Filing Requirements

Once you have Missouri rental income, you establish a tax nexus in Missouri for state purposes. You must file Missouri Form MO-1040(NR) annually, reporting:

• Rental income (gross rents)
• Deductible expenses (property tax, insurance, maintenance, depreciation)
• The net income is taxed at 4.7%

Note: Missouri taxes depreciation recapture at ordinary income rates (up to 25% federal), but depreciation itself reduces your Missouri taxable income dollar-for-dollar.

Property Tax Considerations

Missouri residential property tax assessments vary by county. For rental property, assessor's offices classify the property as "residential rental" (typically 12% of assessed value). With an effective rate of 1.01% statewide, a $300,000 rental home incurs approximately $3,030 in annual property tax.

Missouri allows rental property owners to appeal assessments through the county assessor's office, with a deadline typically 30 days after assessment notice. This deduction directly reduces your Missouri taxable income.

Withholding on FIRPTA Sales

If you sell the Missouri property and the buyer does not withhold 15% under FIRPTA, you remain liable for the full federal and state tax. When you file Form 8288-B with your ITIN, report the sale date, property address, sale price, and any amounts withheld. If overwitheld, you can claim a refund on your 1040-NR.

Common Mistakes to Avoid

1. Incomplete Documentation The IRS rejects applications with missing supporting documents. Always photocopy both sides of your passport and include proof of Canadian residency (T1 return or Notice of Assessment).

2. Mismatched Name Spelling Ensure your name on Form W-7 matches your passport exactly. Any variance (e.g., "John James Smith" vs. "J. James Smith") triggers rejection and reprocessing delays.

3. Applying Too Late Apply for the ITIN before filing your first 1040-NR or immediately when you become aware of a planned property sale. Filing both the W-7 and 1040-NR simultaneously can delay processing of both documents.

4. Not Using ITIN on Follow-Up Returns Once issued, always use your ITIN on subsequent 1040-NR and Missouri MO-1040(NR) filings. The IRS cross-references ITINs annually; failing to use it consistently flags returns for additional scrutiny.

5. Failing to Report FIRPTA Sales If you receive FIRPTA withholding but never file Form 8288-B or report the sale on your 1040-NR, the IRS will issue notices and demand payment. Always file Form 8288-B when Missouri property is sold.

Key Deadlines

• Form W-7 Application: Submit before filing your first 1040-NR (ideally in your year of first rental income or sale) or immediately when a
