“Moving into a higher tax bracket” is one of the most misunderstood ideas in personal tax. A higher bracket never applies to your whole salary, only to the part of it that falls inside that bracket. This post shows how that works, using every point at which the marginal rate changes for an employee in Ontario in 2026, computed by the same engine as our calculator.
Two different rates
Your average rate is the share of your whole salary that goes in income tax and payroll contributions. Your marginal rate is the share of your next dollar that does. Because brackets apply slice by slice, the average rate always trails behind the marginal rate:
| Salary | Tax and contributions | Average rate | Marginal rate |
|---|---|---|---|
| $30,000 | $4,518 | 15.1% | 25.2% |
| $50,000 | $9,855 | 19.7% | 25.2% |
| $75,000 | $18,074 | 24.1% | 32.5% |
| $100,000 | $25,794 | 25.8% | 31.5% |
| $150,000 | $45,680 | 30.5% | 43.4% |
| $250,000 | $93,454 | 37.4% | 49.8% |
Does a raise ever leave you worse off?
No. Up to $300,000, the highest marginal rate in Ontario is 73.3%, between $201,127 and $201,727. Even there you keep 26.7% of each extra dollar. Because the marginal rate never reaches 100%, a higher salary always means higher take-home pay.
Every point where the rate changes
Each row is a range of salary with one marginal rate. The last column shows which deductions changed their own rate at the start of that range, which is why the total moved.
| Salary range | Marginal rate | What changed |
|---|---|---|
| $0 – $3,500 | 1.6% | — |
| $3,500 – $13,828 | 7.6% | CPP contributions 0.0% → 6.0% |

| $68,900 – $72,691 | 34.4% | Federal income tax 19.4% → 19.6%; Ontario income tax 8.7% → 8.8%; EI premiums 1.6% → 0.0% |
| $72,691 – $73,297 | 59.1% | Ontario Health Premium 0.0% → 24.8% |
| $73,297 – $74,600 | 34.4% | Ontario Health Premium 24.8% → 0.0% |
| $74,600 – $85,000 | 32.5% | Federal income tax 19.6% → 19.7%; CPP contributions 6.0% → 0.0%; CPP2 contributions 0.0% → 4.0% |

| $98,590 – $108,912 | 31.5% | Ontario surtax 0.0% → 1.8% |
| $108,912 – $115,037 | 33.9% | Ontario income tax 9.2% → 11.2%; Ontario surtax 1.8% → 2.2% |
| $115,037 – $118,172 | 37.9% | Ontario surtax 2.2% → 6.2% |
| $118,172 – $151,127 | 43.4% | Federal income tax 20.5% → 26.0% |
| $151,127 – $182,567 | 45.0% | Ontario income tax 11.2% → 12.2%; Ontario surtax 6.2% → 6.8% |
| $182,567 – $201,127 | 48.3% | Federal income tax 26.0% → 29.3% |
| $201,127 – $201,727 | 73.3% | Ontario Health Premium 0.0% → 25.0% |
| $201,727 – $221,127 | 48.3% | Ontario Health Premium 25.0% → 0.0% |
| $221,127 – $259,609 | 49.8% | Ontario income tax 12.2% → 13.2%; Ontario surtax 6.8% → 7.4% |
| $259,609 and up | 53.5% | Federal income tax 29.3% → 33.0% |
Some changes look odd at first: federal tax's rate shifts slightly at the EI ceiling because EI premiums also earn a tax credit, and that credit stops growing when the premiums do.
The Ontario Health Premium steps
Several of the short spikes in the table come from the Ontario Health Premium. It does not rise smoothly with income: it climbs in steps, each phased in over a narrow range of salary, and then stays flat until the next step. Below $300,000 that happens 5 times, at $20,166–$25,217 (31.1%), $36,328–$36,934 (49.9%), $48,449–$49,055 (49.9%), $72,691–$73,297 (59.1%), $201,127–$201,727 (73.3%). A raise that lands inside one of these ranges is taxed heavily on that small slice, but the premium stops rising at the top of the range, so the rate falls straight back.
When the rate goes down
The marginal rate can fall as income rises. That happens when a payroll contribution reaches its yearly ceiling and stops being charged on further pay: EI premiums at $68,900; CPP contributions at $74,600; CPP2 contributions at $85,000. Above those points every extra dollar is free of that deduction.
