Quebec administers its own income tax separately from CRA, the only province in Canada to do so. Quebec residents file two tax returns each year: a federal return with CRA and a provincial return with Revenu Québec. To compensate Quebec for opting out of certain shared-cost federal programs, Ottawa applies the Quebec abatement: a 16.5 percentage-point reduction in basic federal tax for all Quebec tax filers. This makes effective combined rates in Quebec lower than the headline federal + provincial sum suggests — but Quebec’s provincial rates are higher, so the net total still places Quebec near the top of provincial tax bands.
Quick answer: Combined federal (after 16.5% Quebec abatement) + Quebec marginal rates for 2026 range from about 26% on low income to 53.31% at the top above $258,482. Quebec has four brackets (14%, 19%, 24%, 25.75%) and the highest provincial BPA on the country at $18,952.
What this means: Quebec’s headline federal rates are reduced by the 16.5% abatement; in exchange, Quebec runs many programs federally administered elsewhere (parental insurance, prescription drug plan, QST). Effective Quebec rates are not directly comparable to other provinces without adjusting for these.

Federal income tax brackets, 2026 tax year
The same federal brackets apply to residents of every province. The bottom federal rate was reduced from 15% to 14% effective July 2025 (Bill C-4); the 2026 tax year is the first full year at 14%.
| Taxable income range | 2026 federal rate |
|---|---|
| Up to $58,523 | 14% |
| $58,523 to $117,045 | 20.5% |
| $117,045 to $181,440 | 26% |
| $181,440 to $258,482 | 29% |
| Over $258,482 | 33% |
The federal basic personal amount (BPA) for 2026 is $16,452 for taxable income up to $181,440. The BPA is reduced gradually for incomes above that level, reaching $14,829 at incomes of $258,482 or more.
Quebec provincial brackets, 2026 tax year
Revenu Québec indexed thresholds by 2.05% for 2026. The provincial rates themselves are unchanged from 2025.
| Taxable income range | 2026 Quebec rate |
|---|---|
| Up to $54,345 | 14% |
| $54,345 to $108,680 | 19% |
| $108,680 to $132,250 | 24% |
| Over $132,250 | 25.75% |
Quebec’s 2026 basic personal amount is $18,952 (up from $18,571 in 2025) — the highest provincial BPA in Canada.
The Quebec abatement
The Quebec abatement reduces basic federal tax payable by 16.5% for all Quebec tax filers. This applies to net federal tax (after the BPA credit). It is the federal government’s mechanism for compensating Quebec for opting out of certain shared programs (cash equivalent of the value of those programs).
For combined rate calculations, the abatement reduces the effective federal rate by 16.5%:
- 14% federal × (1 − 0.165) = 11.69% effective
- 20.5% × 0.835 = 17.12%
- 26% × 0.835 = 21.71%
- 29% × 0.835 = 24.22%
- 33% × 0.835 = 27.56%
Combined federal (after abatement) + Quebec marginal rates (2026 tax year)
| Taxable income range | Approximate combined marginal rate |
|---|---|
| Up to $54,345 | ~25.69% (11.69% federal + 14% Quebec) |
| $54,345 to $58,523 | ~30.69% |
| $58,523 to $108,680 | ~36.12% |
| $108,680 to $117,045 | ~41.12% |
| $117,045 to $132,250 | ~45.71% |
| $132,250 to $181,440 | ~47.46% |
| $181,440 to $258,482 | ~49.97% |
| Over $258,482 | 53.31% |
Other Quebec-specific items
- Health Services Fund contribution — included in the Quebec tax base, not a separate line at most income levels.
- Quebec Pension Plan (QPP) instead of CPP — slightly higher rate (6.40% employee vs CPP’s 5.95%).
- Quebec Parental Insurance Plan (QPIP) — small additional payroll deduction not present in other provinces.
- Higher EI premium reduction — Quebec EI rate is 1.26% in 2026 versus 1.63% elsewhere because QPIP covers parental benefits.
- Quebec Sales Tax (QST) — 9.975% on top of 5% federal GST, administered by Revenu Québec.
Worked example
Marie earns $85,000 of taxable income in Quebec in 2026:
| Component | Tax |
|---|---|
| Federal: $58,523 at 14% | $8,193 |
| Federal: $26,477 at 20.5% | $5,428 |
| Federal BPA credit (14% × $16,452) | −$2,303 |
| Federal tax before abatement | $11,318 |
| Quebec abatement (−16.5%) | −$1,867 |
| Net federal tax | $9,451 |
| Quebec: $54,345 at 14% | $7,608 |
| Quebec: $30,655 at 19% | $5,824 |
| Quebec BPA credit (14% × $18,952) | −$2,653 |
| Net Quebec tax | $10,779 |
| Total federal + Quebec tax | ~$20,230 |
| Average rate ($20,230 / $85,000) | ~23.8% |
| Marginal rate on next $1,000 | ~36.12% |
This excludes QPP, QPIP, and EI deductions; the gross paycheque deduction in Quebec is meaningfully higher than the tax figure alone.
Frequently asked questions
- What are the Quebec tax brackets for 2026?
- Four brackets: 14% up to $54,345, 19% to $108,680, 24% to $132,250, and 25.75% above $132,250. Revenu Québec indexed thresholds by 2.05% for 2026.
- What is the Quebec abatement?
- A 16.5% reduction in basic federal tax for all Quebec residents, applied automatically when you file your federal return. It compensates Quebec for opting out of shared-cost federal programs and effectively lowers your federal rate.
- What is the Quebec basic personal amount?
- $18,952 for 2026, up from $18,571 in 2025. It is the highest provincial BPA in Canada.
- Why do I file two tax returns in Quebec?
- Quebec is the only province that administers its own income tax. You file a federal return with CRA and a provincial return with Revenu Québec each year.
- What is the top combined federal + Quebec rate?
- 53.31% on income above $258,482 for the 2026 tax year (combining the 33% federal rate after 16.5% abatement with the 25.75% top Quebec rate).
- How does Quebec EI differ from the rest of Canada?
- Quebec residents pay a reduced EI rate of 1.26% in 2026 (vs 1.63% in other provinces) because the Quebec Parental Insurance Plan (QPIP) provides parental benefits separately.
- Does the Quebec abatement reduce the BPA credit?
- Yes. Because the abatement is applied to net federal tax after the BPA credit, the federal personal amount credit is effectively reduced by 16.5% for Quebec residents. This is built into the combined-rate calculation.
