Selling a Property in Ontario? Don't Forget the Vacant Home Tax Declaration

Sellers preparing to list a property in a municipality with a vacant home tax program often focus entirely on getting the home market-ready — and understandably so. But the property's vacant home tax declaration history is quietly part of the closing picture too, and an unfiled or overdue declaration can surface at exactly the wrong moment: during a buyer's due diligence, or after closing when it becomes the new owner's problem to untangle with your name still attached to the prior period.

Here's what sellers should keep in mind.

Why This Is a Seller Issue, Not Just a Buyer Issue

Because vacant home tax declarations are typically tied to a property owner for a specific reporting period, a seller who owned the home during that period generally remains responsible for that period's declaration and any resulting tax — even after the sale closes and the buyer takes over. An unresolved declaration from your ownership period doesn't automatically transfer to the new owner just because the property has changed hands.

If a buyer's lawyer asks about vacant home tax status as part of due diligence — increasingly common in municipalities that run these programs — sellers who haven't kept their filings current can find themselves scrambling to sort it out mid-transaction.

What Sellers Should Check Before Listing

• Confirm your municipality runs a vacant home tax program. If it does, this is relevant to your sale; if it doesn't, you can set this issue aside.
• Review your declaration history. Confirm that all required declarations for periods you owned the property have actually been filed, not just that you intended to file them.
• Check for any outstanding balance. If a default vacancy assessment was triggered by a missed filing in a prior year, there may be a balance sitting on the municipal tax account.
• Address the current reporting period. Depending on timing, you may need to file (or plan to file) a declaration covering the period up to your sale, even if the sale closes before the municipality's usual annual deadline.

How This Typically Gets Handled at Closing

1. Disclosure and confirmation. The seller's lawyer confirms the property's declaration and tax status, similar in spirit to how property tax arrears are confirmed before closing.
2. Resolving any outstanding balance. If arrears exist from the seller's ownership period, they're typically addressed through the statement of adjustments or resolved directly before closing, so the balance doesn't transfer forward as the buyer's problem.
3. Clarifying responsibility for the transition period. Because ownership is changing mid-cycle, the buyer and seller (through their lawyers) typically sort out who is responsible for the next declaration covering the period around the sale.
4. Closing proceeds accordingly. Once the vacant home tax picture is confirmed and any necessary adjustment made, this becomes one more resolved item alongside the usual closing mechanics.

What Happens If You Discover a Missed Declaration Late

If you realize, in the middle of preparing to sell, that a prior year's declaration was never filed, don't ignore it hoping it won't come up. Most municipalities have some process to file late or correct a default assessment, though the process and any applicable fee vary by city. Addressing it proactively — before a buyer's lawyer raises it — generally puts you in a stronger position than reacting to it mid-negotiation.
