Canada operates a two-layer income tax system: a uniform federal schedule applied to every taxpayer, plus a province- or territory-specific schedule stacked on top. The combined marginal rate at any income level is the sum of the two schedules. This guide walks through the federal layer, the provincial layer, and how PlainRRSP encodes them.
The 2026 federal brackets
Federal brackets for 2026 are: 14% up to $58,523; 20.5% from there to $117,045; 26% from there to $181,440; 29% from there to $258,482; and 33% above that (the lowest bracket dropped from 15% to 14% under the federal middle-class tax cut). Federal brackets are identical across the country and do not vary by province.
The provincial layer
Each province publishes its own bracket schedule via its provincial budget, typically released in spring or fall. The bracket cut-offs and rates vary considerably: Alberta runs a flat 10% bracket up to a high threshold; Quebec runs the highest provincial rates in the country at the top end; the Atlantic provinces sit somewhere in between. PlainRRSP carries full bracket schedules for all 13 provinces and territories, see the provincial rankings page to compare them side by side; Ontario is walked through in detail below.
Ontario 2026 brackets, a worked example
| Bracket | From | To | Rate |
|---|---|---|---|
| 1 | $0 | $52,886 | 5.05% |
| 2 | $52,886 | $105,775 | 9.15% |
| 3 | $105,775 | $150,000 | 11.16% |
| 4 | $150,000 | $220,000 | 12.16% |
| 5 | $220,000 | and up | 13.16% |
The Ontario surtax (an additional levy of 20% and 36% on certain bracket thresholds) is not modelled in Phase 1; it is added in Phase 2.
The Quebec abatement
Quebec residents are subject to a unique provincial tax administration: the provincial tax is collected by the Quebec Ministry of Revenue (MRQ) rather than the CRA, and the federal portion is reduced by a 16.5% abatement. Quebec also has its own brackets, which are more progressive than most provinces. Phase 2 of PlainRRSP will model the abatement explicitly.
Why this matters for RRSP / TFSA decisions
Combined marginal rate at your current income level is the single most important input to the RRSP-vs-TFSA decision. A high-income Albertan and a high-income Newfoundlander face very different effective marginal rates despite identical federal-bracket positioning. The PlainRRSP calculator encodes each province's full schedule so the deferral calculation matches your actual situation, not a national average.
Update cadence
Provincial brackets typically refresh once per year, although mid-year amendments via supplementary budgets happen occasionally. The CRA's withholding schedules incorporate the latest provincial rates within a few weeks of each provincial budget; PlainRRSP refreshes within days of the official rate notice.

Registered-account reference
RRSP, TFSA and RESP rules each have separate contribution-room mechanics. Use your latest CRA deduction-limit statement as the authoritative figure for an RRSP decision; a Notice of Assessment, reassessment, Form T1028 and the CRA account can change that figure.
Pension adjustments and unused RRSP room
A pension adjustment is reported in box 52 of a T4 or box 034 of a T4A and generally reduces the following year's RRSP deduction limit. Unused RRSP room can carry forward, but the amount available to deduct is the figure the CRA records for you. Read the CRA pension-adjustment guidance.
Excess-contribution rules
The CRA says unused RRSP contributions that exceed the deduction limit by more than $2,000 generally face a 1% monthly tax. TFSA excess amounts are also generally taxed at 1% per month. Remove an excess promptly and use the CRA's instructions for the relevant return rather than relying on a generic cleanup rule. RRSP excess-contribution rules and TFSA excess-contribution rules explain the exceptions, calculation and filing steps.
2026 registered-account contribution ceilings
| Account | 2026 ceiling | What the figure covers |
|---|---|---|
| RRSP | 18% of earned income, up to $33,810 | Annual deduction limit; personal available room is CRA-specific |
| TFSA | $7,000 | Annual room; withdrawals return as room in the next calendar year |
| RESP | $50,000 lifetime per beneficiary | Basic CESG: $500 annually, up to $7,200 lifetime |
