The short answer
In Gatineau, the city announces a 2026 tax bill of $3,575.15 for its reference property, up 3%.
The 2026 tax bill in Gatineau
$3,575.15: this is the 2026 tax bill published by the city. What the city means by it: 2026 tax bill for a MEDIAN home assessed at $454,600 (phased-in value for 2026), total by sector before former-city taxes; with those taxes, from $3,575.15 (Masson-Angers) to $3,591.52 (Hull). Excludes local improvements and pools. This is not an average.
Increase announced by the city for 2026: +3%. Each city measures its increase its own way (with or without water, waste collection or special taxes): compare the bills, not just the percentages.
For reference, a house sold for $490,000 at the 2026 median on Centris (1,832 sales). The municipal assessment, used to calculate taxes, often differs from the sale price.
The property tax rate in Gatineau
The city does not publish a single residential rate for 2026 (see the other rates below).
Other rates: The residential category tax has no single rate: the 2026 budget states “Par unité de voisinage” (by neighbourhood unit) (the City has taxed by neighbourhood unit since the 2024-2026 roll). Uniform 2026 rates, per $1,000 of assessment: 6 dwellings or more category $6.964; public transit $1.417; new city debt service $0.830. Sector taxes for the former cities' debts: Buckingham $0.018 and Hull $0.036 per $1,000; Aylmer $6.42 and Gatineau $9.53 per dwelling.
Fixed fees: Waste management: $178.83 per dwelling in 2026 (increase of $4.22 announced).
The assessment roll in Gatineau
2024-2025-2026 roll (2026 is its third and final year).
Calculating the taxes on a house in Gatineau
The general property tax is calculated as: municipal assessment × rate ÷ 100. The actual bill for an address is on the city's online assessment roll and on the seller's latest tax bill: ask for it before making an offer.
The 2026-2027 school tax
The school tax is not set by the city. Since 2020-2021, the rate is the same everywhere in Quebec: $0.07899 per $100 of standardized assessment for 2026-2027 ($0.08423 in 2025-2026), and the first $25,000 of value is exempt. It is calculated on the standardized value, which can differ from the roll value. Example: for a standardized value of $500,000, the 2026-2027 school tax would be about $375.
Before buying in Gatineau
- Ask for the seller's latest tax bill and the roll assessment of the address: it is the only exact figure for your budget.
- Check the roll year. After a new roll, the assessment can jump: next year's bill will not be this year's.
- Count the sector fees (water, sewers, garbage, local improvement taxes): two houses of the same value in the same city can pay different amounts.
- Include taxes in the mortgage calculation. The lender includes them in your debt ratios: the welcome tax is paid once, property taxes every year.
