TAL Rent Increase Calculator 2026: How to Calculate Your Quebec Rent Adjustment

The TAL published new calculation criteria for rent increases effective January 1, 2026. The old 13-component grid is gone. In its place is a simplified formula built around a CPI base rate — but "simplified" doesn't mean obvious. Here's how to actually run the numbers for your property.

The Five Components

Every rent increase under the 2026 method has five possible components. You start with the base rate, then add adjustments only where they apply.

1. Base CPI adjustment (3.1%)

Multiply your current monthly rent by 3.1%. For a $1,400/month unit, that's $43.40. This applies to every standard residential lease, regardless of whether you supply heat or not. The old separate rates for heated vs. unheated dwellings are gone.

2. Property and school tax variance

Pull your municipal and school tax bills for the preceding year and the current reference year. Calculate the percentage increase. If that increase exceeds 3.1%, you add only the excess portion, proportioned to the unit's share of total building revenue.

Example: taxes went from $2,000 to $2,140 — a 7% increase. The first 3.1% ($62) is absorbed by the base rate. The excess is $140 − $62 = $78 per year. For a triplex with equal units, one unit's share is $78 ÷ 3 = $26/year, or $2.17/month.

If your taxes increased by 3.1% or less, this component is zero.

3. Insurance premium variance

Same logic as taxes. Compare your fire and liability insurance premiums year-over-year. Only the portion exceeding a 3.1% increase counts. If your insurance went up 2%, this component is zero — the base rate already covers it.

4. Capital expenditures

Major work completed during the reference calendar year — roof replacement, window installation, structural masonry, unit overhauls — gets amortized at a fixed 5% annual rate. Subtract any government subsidies or insurance payouts first.

Example: you spent $6,000 on a new roof for your triplex. One unit's share is $2,000. At 5% amortization, that's $100/year or $8.33/month. This amount repeats annually for 20 years (5% × 20 = 100% of the expense recovered).

5. Seniors' personal services (if applicable)

For seniors' residences that include personal assistance services, the applicable rate is 6.7% on that portion.

Putting It Together

For that $1,400/month triplex unit with a 7% tax increase and a $6,000 roof:

New rent: $1,453.90/month. The actual percentage depends entirely on your property's expenses — two landlords on the same street can have different lawful increases.

The TAL's Online Tool vs. Manual Calculation

The TAL website offers a Calcul 2026 tool at tal.gouv.qc.ca. It's useful for a quick check, but know its limits: the output is non-binding unless ratified by a formal TAL order, and the interface is French-first. English landlords often struggle with the field labels.

For a TAL hearing, you'll need to complete Form RN_2026_A — the mandatory information form for rent-fixing proceedings. That form requires detailed financial reporting for the entire building during the reference calendar year, including original tax bills, insurance invoices, and contractor receipts.

Common Mistakes

Treating the 3.1% as a cap. It's a baseline. Your lawful increase can be higher or lower depending on your actual expenses.

Using last year's rates. The legacy method (4.5% base, variable energy components, 4.0% CapEx) applies to notices served before January 1, 2026. For notices served on or after that date for renewal periods starting between April 2, 2026 and April 1, 2027, use the new formula.

Forgetting the unit share. Building-wide expenses must be proportioned to the target unit's share of gross revenue. A $6,000 roof on a triplex means $2,000 per unit — not $6,000.

Counting subsidized amounts. Government grants, insurance reimbursements, and subsidies must be subtracted from capital expenses before you apply the 5% rate.
