In short · September 28, 2026
A review request (demande de révision) costs $80 to $90 for a property worth $500,000 or less in Quebec’s large cities, and up to $1,215 above $5M in Montréal. The savings are calculated this way: value reduction ÷ 100 × your property tax rate, multiplied by the years left on the roll.
Filing fees, city by city
Fees are set by municipal by-law, by value bracket on the roll. The Act caps them at the TAQ rate for the same unit. Montréal specifies that its fees are non-refundable. Laval: rates taken from the official page; Gatineau: By-law 943-2023, which may be revised for the 2027 roll.
| Value on the roll | Montréal | Québec | Laval | Gatineau | TAQ (2026) |
|---|---|---|---|---|---|
| $500,000 or less | $90 | $85 | $85 | $80 | $93.20 |
| $500,001 to $2M | $360 | $355 | $350 | $325 | $372.60 |
| $2M to $5M | $605 | $590 | $575 | $574.50 | $621.10 |
| Over $5M | $1,215 | $1,180 | $1,150 | $1,149.25 | $1,242.50 |
How to calculate the savings
Property taxes are calculated in dollars per $100 of assessment. Your tax bill shows your rate. The formula:
Annual savings = value reduction ÷ 100 × tax rate. Then multiply by the number of years left on the roll: a reduction obtained in the first year applies to all three years of the roll.
Example, with fictional figures to replace with your own: a house assessed at $500,000, an 8% reduction ($40,000), a rate of $0.80 per $100. The savings are 40,000 ÷ 100 × 0.80 = $320 per year, or $960 over three years, for filing fees of $85 to $90. The $0.80 rate is an example: use the one on your tax bill.
For a sense of scale: in Montréal, the director of property assessment told La Presse that values go down in about 40% of cases, in the range of 8% to 10%. In other words, in most cases the value does not go down.
The costs people forget
- Your time: gathering comparable sales and evidence takes a few hours.
- A chartered appraiser’s report, often useful for a plex or before the TAQ. See how much a home appraisal costs.
- A TAQ appeal, if you need to go further: $93.20 to $1,242.50 in 2026, depending on the value.
- The risk of an increase: a request reopens the file, and the value can also go up.

Talk to a chartered appraiser in your area
For a plex, an income property, a file headed to the TAQ or any value you are seriously challenging, a chartered appraiser is the right person. Payotte has verified 30 in Quebec, one per sector, selected on public data, never on their budget.
