Ottawa Vacant Unit Tax When Buying or Selling a Home: A Closing Checklist

Published September 29, 2026 · Meysami Law Professional Corp. · Ottawa

Ottawa's Vacant Unit Tax is administered through the property-tax account, so it deserves attention when a residential property changes ownership. The seller, buyer, real-estate lawyer and tax office may each need different information depending on the closing date and the occupancy year. Addressing the issue before closing can reduce uncertainty about declarations, exemptions and amounts attached to the property.

Start with the closing date

The City of Ottawa's change-of-ownership guidance separates transactions by timing. For a closing between January 1 and April 30, the seller is responsible for completing the declaration for the previous occupancy year. For a closing between May 1 and December 31, the buyer must submit a declaration in the following year. Confirm the current City instructions for the transaction year rather than relying on an old checklist.

Ask for the declaration and tax-account evidence

Before closing, identify whether the property was declared, whether the City treated it as vacant, and whether any VUT amount, penalty or interest appears on the tax account. A declaration confirmation, current tax certificate or other appropriate closing evidence may help the parties and their lawyers determine what must be addressed. The required evidence depends on the file.

Understand the change-of-ownership exemption

Ottawa's program includes an exemption for qualifying sales, but an exemption is not the same as ignoring the declaration. The person responsible for the applicable declaration must still select the appropriate status and satisfy the City's requirements. The agreement of purchase and sale should not be treated as proof that every VUT step has been completed.

Treat unpaid VUT as a property issue

The City states that the VUT forms a lien on the property in the same way as property taxes. Unpaid amounts can therefore become the buyer's responsibility after closing. This is why the tax account, adjustments and any holdback or undertaking questions should be reviewed as part of the legal closing process rather than left to informal discussion.

Keep occupancy facts and records

Owners should retain records supporting how the property was occupied and any exemption claimed. For a transaction, useful records may include the agreement, statement of adjustments, possession date, tenancy information, renovation or construction records, and City correspondence. Do not send sensitive records through a public website form.

Build VUT into the closing conversation

Tell your real-estate lawyer if the property was vacant, rented, under construction, used by a permitted occupant or affected by an estate or other special circumstance. Ask who will complete the relevant declaration, what evidence is needed, and how any assessed amount will be handled on closing. City rules and annual deadlines can change, so current instructions should be checked for the year involved.
