The Hidden Tax Trap When Buying a Home

November 1, 2026

Imagine moving into your new home, only to receive a massive bill from the Canada Revenue Agency (CRA) months later demanding tens of thousands of dollars. It sounds impossible—especially if your lawyer gave the green light and your title search came back clean.

Yet, this happens to unsuspecting Canadian buyers due to a little-known rule under Section 116 of the Income Tax Act.

When a non-resident sells Canadian real estate, they owe capital gains tax. If they leave the country without paying, the CRA legally shifts that tax burden directly to the buyer. Because this liability attaches to you personally—not the property—a “clean title” or standard title insurance won’t automatically shield you.

Worse, the CRA requires a statutory withholding of 25% to 50% of the gross sale price (not the seller’s profit). On a $1 million home, that could mean a $250,000 to $500,000 surprise.

How to Protect Yourself

Courts require buyers to make a “reasonable inquiry” into the seller’s tax residency. A simple checkmark on a boilerplate form is not enough if red flags exist—such as a seller living abroad, using a foreign bank account, or signing via an overseas power of attorney.

Before you close, take these essential precautions with your real estate lawyer:

  • Demand a sworn declaration: Require the seller to swear under oath (via a formal Statutory Declaration) that they are a Canadian resident for tax purposes.

  • Require a CRA Certificate of Compliance: If the seller is a non-resident, they must obtain this certificate confirming they’ve settled their taxes.

  • Hold back the funds: Because CRA certificates take months to process, ensure your lawyer holds 25% to 50% of the purchase price in trust until the CRA grants clearance.

Never assume clear title equals clear taxes. Asking the right residency questions before closing can save you from paying someone else’s tax debt.

A buyer cannot simply rely on a standard boilerplate clause if obvious signs of non-residency are present. Under Canadian case law (such as Kau v. The Queen), buyers and their solicitors have an obligation to make further inquiries whenever objective indicators suggest the vendor may not reside in Canada for tax purposes.

The primary red flags in residential transactions include:

1. Document Execution & Signatures

  • Execution Outside Canada: Closing documents, affidavits, or agreements executed before a foreign notary, consular official, or outside the country.
  • Foreign Power of Attorney (POA): The seller does not sign directly, instead designating a local friend, relative, or attorney through a POA executed abroad.
  • Remote Digital Signatures from Foreign IP Addresses / Time Zones: Notarizations or electronic signature audit trails originating from non-Canadian jurisdictions.

2.  Contact & Address Details

  • Foreign Address for Service: The seller’s stated address for service on the transfer deed, listing agreement, or land registry parcel is outside Canada.
  • Out-of-Country Contact Information: Foreign phone numbers, international country codes, or overseas mailing addresses on correspondence or utility records.
  • Absence of a Canadian Primary Residence: The seller has no other Canadian home and lists an overseas residence as their principal contact location.

3.  Banking & Fund Routing

  • Offshore Wire Instructions: Directions to wire the closing balance directly to a foreign bank account or to an offshore financial institution.
  • Third-Party Payment Directions: Directions to pay proceeds to third-party entities, offshore corporations, or non-resident family members rather than the registered titleholder’s Canadian account.

4. Property Usage & Tenancy

  • Pure Investment / Tenanted Property: The property was never owner-occupied and was managed strictly through a local property management firm or third-party agent while the owner remained abroad.
  • Vacant or Staged-Only Homes: High-end homes or condos that have sat vacant, unfurnished, or purely staged with no signs of personal domestic ties in Canada.

5. Identification & Tax Records

  • Absence of a Social Insurance Number (SIN): The seller cannot provide a Canadian SIN or instead holds an Individual Tax Number (ITN, beginning with 09) issued by the CRA specifically for non-residents.
  • Hesitation Around Sworn Declarations: The seller or their lawyer resists delivering a formal, sworn Statutory Declaration under the Canada Evidence Act confirming Canadian residency status on the closing date, offering only an informal or unsworn statement.
