Form W-7 for Canadian Landlords in Delaware

What Is Form W-7 and Why You Need It

Form W-7 (Application for IRS Individual Taxpayer Identification Number) is the IRS application used to obtain an Individual Taxpayer Identification Number (ITIN). An ITIN is a nine-digit tax identification number that the IRS issues to non-residents and foreign nationals who have US tax obligations but do not qualify for a Social Security Number.

As a Canadian landlord earning rental income from Delaware property, you are classified as a non-resident alien for US tax purposes. The IRS requires you to have either a Social Security Number or an ITIN to file Form 1040-NR (Non-resident Alien Income Tax Return) and to satisfy FIRPTA (Foreign Investment in Real Property Tax Act) withholding obligations when you eventually sell your property.

Without an ITIN, you cannot:

• File a US federal tax return for rental income
• Comply with FIRPTA withholding requirements on property disposition
• Claim tax treaty benefits under the Canada-US Tax Treaty
• Obtain a Delaware rental property tax identification number

How the ITIN Requirement Applies to Delaware Landlords

Delaware presents a unique tax situation for Canadian rental property owners. While Delaware has no sales tax and minimal corporate taxes, it does impose a 6.6% state income tax on rental income earned within the state. This applies equally to non-residents.

Here's the Delaware-specific filing framework:

Federal Level: You must file Form 1040-NR with the IRS by June 15 (for non-residents) using your ITIN.

Delaware State Level: You must file a Delaware Nonresident Income Tax Return (Form 1040A or equivalent) by April 15 of the following year, also using your ITIN. Delaware's 6.6% flat tax rate applies to net rental income less allowable deductions (mortgage interest, property tax, repairs, management fees, utilities, insurance, depreciation).

Property Tax: Delaware's effective property tax rate averages 0.57%, assessed at the county level. This is deductible against both federal and state taxable income.

FIRPTA Considerations: If you sell your Delaware property, the buyer's agent or title company must withhold 15% of the gross sale price and remit it to the IRS. Your ITIN is essential to claim this as a credit or obtain a refund.

Who Must File Form W-7

You must file Form W-7 if you are:

• A Canadian citizen or permanent resident with no US Social Security Number
• Earning rental income from Delaware residential or commercial property
• Subject to US tax filing obligations for that rental income
• Required to satisfy FIRPTA withholding requirements
• Claiming treaty benefits under Article IV(g) of the Canada-US Tax Treaty (which may exempt certain types of income or allow reduced withholding)

You do not need to file W-7 if you already hold a valid Social Security Number or ITIN.

Step-by-Step: How to Complete Form W-7

Step 1: Gather Required Documents

Before submitting Form W-7, collect:

• Proof of Canadian citizenship: Valid Canadian passport or provincial ID (certified copy or original)
• Proof of foreign status: Your Certificate of Canadian Citizenship or Permanent Residency document
• Tax return documentation: A copy of your most recent Canadian T1 General (personal income tax return), which demonstrates your tax filing history
• Lease agreements or property title: Documentation showing your ownership interest in the Delaware property
• IRS Form 8288-B: If applicable, evidence that FIRPTA withholding was already collected on a property sale

Step 2: Complete Form W-7 Accurately

Part I – Personal Information:

• Enter your full legal name as it appears on your Canadian passport (first name, middle initial, last name)
• Provide your date of birth in MM/DD/YYYY format
• Enter your Canadian mailing address or US address (if you have one)

Part II – Country of Citizenship and Residency:

• Enter Canada as country of citizenship
• Enter Canada as country of residency

Part III – Type of Applicant:

• Check box "Other" and write: "Non-resident alien deriving US-source rental income from Delaware real property"

Part IV – Intended Use of ITIN:

• Check "Federal tax return filing" (mandatory)
• Check "FIRPTA" (if you own property subject to potential sale)

Part V – Declaration:

• Sign and date the form under penalty of perjury

Step 3: Submit with Supporting Documents

The IRS requires original or certified copies of identity documents. Do not send originals to the IRS if possible; instead:

• Mail Form W-7 with certified photocopies to the appropriate IRS ITIN Unit (in Philadelphia for Delaware applicants)
• Include a cover letter explaining that you are a Canadian landlord deriving rental income from Delaware property
• Attach a copy of the Canada-US Tax Treaty (Article IV, Article XIII) to establish non-resident status
• Include a copy of your most recent T1 return with the Canadian Revenue Agency

Current mailing address for Delaware applicants: IRS ITIN Operations Philadelphia Field Office 1601 Market Street Philadelphia, PA 19103

Step 4: Processing Timeline

• Processing time: 4–6 weeks if submitted by mail with complete documentation
• ITIN validity: Valid for five years if not used; must renew if it expires
• Follow-up: You will receive IRS Notice CP565 (ITIN Assignment Notice) confirming your number

Delaware-Specific Considerations

1. Property Tax Deductibility

Delaware's 0.57% average effective property tax rate is fully deductible against Delaware taxable income on your state return (Form 1040A). Ensure you claim the actual county-assessed property tax amount; real estate transfer tax (2.5%) on purchase is typically not deductible as an operating expense.

2. Delaware's Employer Withholding Requirement

If your Delaware rental property is managed by a US agent or property management company, Delaware law (Title 30, Section 1701) may require them to withhold 10% of net rental income if you do not provide your ITIN and tax certification. Obtaining your ITIN eliminates this withholding.

3. Canada-US Tax Treaty Implications

Under Article XIII of the Canada-US Tax Treaty, rental income is taxable in both countries. However, Article XXIV(4) allows Canadian residents to claim a foreign tax credit on their Canadian T1 return for Delaware state income taxes paid. You should:

• File Form 8288 (FIRPTA withholding statement) to report state taxes withheld
• Report the same Delaware income on your Canadian T1 return (Line 12699)
• Claim a foreign tax credit (Schedule 1, Line 40426) for Delaware state and local taxes paid

This prevents double taxation.

4. Franchise Tax on Corporations (Not Applicable)

If you operate through a Delaware LLC or corporation, different rules apply. For individual landlords, only the income tax applies.

Common Mistakes to Avoid

1. Submitting an Unfiled W-7 Never submit Form W-7 without attaching a tax return. The IRS will reject it. Submit W-7 with your first 1040-NR or as part of the FIRPTA documentation.

2. Incorrect Applicant Type Selecting the wrong category in Part III causes delays. Clearly indicate "Non-resident alien" status.

3. Using an Expired Canadian Passport The passport must be valid on the date you sign Form W-7. Renew your passport before submitting.

4. Forgetting FIRPTA Withholding Documentation If you previously sold Delaware property and withholding was collected, include Form 8288-B or the settlement statement proving withholding occurred.

5. Incorrect Mailing Address The Philadelphia IRS ITIN Unit handles Delaware. Sending Form W-7 to a general IRS address delays processing by 8–12 weeks.
