Municipal Tax Adjustment When Buying Property in Quebec

The municipal tax adjustment is a proration mechanism standard in Quebec notarial practice, rooted in the Civil Code of Quebec. It ensures each party pays their fair share of property taxes based on the number of days of ownership during the year. Here is how it works, who pays what, and how much to budget for at closing.

Why Is There a Municipal Tax Adjustment?

In Quebec, municipal and school taxes are billed annually, typically from January 1 to December 31. When a property changes hands mid-year, the seller has often already paid all or part of the taxes for the full year. The buyer must therefore reimburse the seller for the portion of taxes corresponding to the period from the closing date to December 31.

This principle stems from contractual fairness: the seller should not bear the cost of taxes for a period during which they no longer own the property. The notary automatically performs this calculation in the statement of adjustments presented at signing. For a comprehensive overview of all purchasing costs, see our complete guide to home buying costs in Quebec.

The Proration Calculation Formula

The calculation is straightforward but its impact is significant. The formula used by notaries is:

Buyer reimbursement = Annual taxes × (Days remaining in year ÷ 365)

The “days remaining” are counted from the closing date (inclusive) to December 31. The notary applies the same logic for school taxes, condo fees (if applicable), and sometimes heating oil or propane.

The Notary’s Role in the Adjustment

The officiating notary is responsible for calculating all adjustments between seller and buyer. This calculation appears in the “statement of adjustments,” a document presented a few days before signing the deed of sale. Beyond municipal taxes, the notary adjusts school taxes, condo fees (if applicable), remaining heating oil or propane, and sometimes pre-collected rents for rental properties.

Municipal Taxes vs School Taxes

Municipal taxes represent the largest share of property taxes in Quebec. They fund municipal services: roads, snow removal, waste collection, recreation, etc. School taxes, much smaller (typically $200 to $600 per year), are also prorated. The school tax fiscal year may differ from the municipal calendar (often July 1 to June 30), which changes the proration calculation.

Special Cases to Know

Unpaid taxes by the seller: If the seller has not paid their taxes, the notary withholds the amount owing from the sale proceeds and pays it directly to the municipality. The buyer then only pays their portion from the closing date onward.

Instalment payments: Many municipalities allow paying taxes in multiple instalments (2, 3, or 4 times per year). The notary verifies which instalments have been paid and adjusts accordingly.

Condominiums: For a condo, condo fees are also prorated for the month. Municipal taxes for condominiums are generally lower than for a single-family home of equivalent value.

How to Plan for the Adjustment in Your Budget

1. Request the tax bill — Your real estate broker can obtain it from the seller or the property listing. The total annual amount is indicated.

2. Estimate based on your closing date — Apply the formula: annual taxes × (days remaining ÷ 365). Allow a 10% buffer for school tax adjustments and other fees.

3. Include this amount in your closing budget — On top of the down payment, notary fees ($1,500 to $2,500), welcome tax, and inspection, the tax adjustment is an amount you need in liquid funds on signing day.

Impact on Your Borrowing Capacity

Annual property taxes factor into your Gross Debt Service (GDS) ratio calculation. High taxes reduce the maximum amount you can borrow. For example, $4,800/year in taxes represents $400/month added to your mortgage payment in the GDS calculation (maximum 32%).
