What makes Ontario income tax different from other provinces?
Ontario is the only province with two add-ons beyond its brackets: the Ontario surtax and the Ontario Health Premium. Everything else on an Ontario return (federal tax, CPP, CPP2, EI) works exactly as it does in every other province outside Quebec, and the Canada-wide income tax calculator walks through those shared steps. This page concentrates on the Ontario part.
The two add-ons hit different people. The premium reaches almost every Ontario worker, starting at just over $20,000 of taxable income, while the surtax only begins near a six-figure salary. Together they explain why Ontario marginal rates jump around far more than the five-row bracket table suggests.
How do you use the Ontario salary calculator?
- Type a yearly Ontario salary, or switch to hourly and add your usual weekly hours.
- Leave the province on Ontario; Ontario tax applies to anyone living here on December 31, 2026.
- Look for the “Ontario Health Premium” and “Ontario surtax” lines in the breakdown: they are the two figures other salary tools most often miss.
- Try an RRSP deduction and watch whether it moves taxable income below a premium step (the table further down lists them).
What are Ontario’s 2026 brackets?
How to read this table: a rate covers only the income between the previous limit and its own; the dash row is open-ended. Ontario tax is added to federal tax, never instead of it.

Only the two lowest limits moved for 2026: on the 2025 return they were $52,886 and $105,775, while the $150,000 and $220,000 limits stayed put. Ontario credits, including the $12,989 basic personal amount, are valued at 5.05%, so that amount is worth $656 off Ontario tax.
How does the Ontario Health Premium work, and where does it spike?
The premium is charged on taxable income in bands. Within each band it grows at 6% or 25% of the income above the band’s start until it hits that band’s cap:
How to read this table: premium = the entering amount + phase-in rate × income above the band's start, capped at the band maximum. Premium amounts and bands are not indexed to inflation.
| Taxable income above | Band ends at | Premium entering the band | Phase-in rate | Most the band can charge |
|---|---|---|---|---|
| $0 | $20,000 | $0 | 0% | $0 |
| $20,000 | $36,000 | $0 | 6% | $300 |
| $36,000 | $48,000 | $300 | 6% | $450 |
| $48,000 | $72,000 | $450 | 25% | $600 |
| $72,000 | $200,000 | $600 | 25% | $750 |
| $200,000 | — | $750 | 25% | $900 |

Because a band’s cap is reached quickly, most of each band is flat. The premium only rises inside five short phase-in zones, and inside those zones it adds 6 or 25 points to the marginal rate:
| Taxable income zone | Premium moves | Extra rate in the zone | Combined marginal rate in the zone |
|---|---|---|---|
| $20,000 to $25,000 | $0 to $300 | 6% | 25.05% |
| $36,000 to $38,500 | $300 to $450 | 6% | 25.05% |
| $48,000 to $48,600 | $450 to $600 | 25% | 44.05% |
| $72,000 to $72,600 | $600 to $750 | 25% | 54.65% |
| $200,000 to $200,600 | $750 to $900 | 25% | on top of a rate already raised by the surtax |
The $72,000 zone matters most, because it sits right at a typical Ontario pay level. Statistics Canada puts Ontario’s average weekly earnings for July 2026 at $1,391.19, or about $72,342 a year. An employee on that salary has taxable income of $71,654, just under the zone. The calculator shows that salaries from about $72,692 to $73,298 pay the 25% premium phase-in on every extra dollar.
When does the Ontario surtax start?
The surtax is 20% of basic Ontario tax above $5,818, plus 36% of basic Ontario tax above $7,446. Since it is measured on tax after credits, the salary where it begins depends on your deductions. For an employee with no RRSP deduction, the calculator finds the first part starting at a salary of about $98,591 and the second at about $115,038.
| Salary | Basic Ontario tax | Surtax | Surtax as a share of basic Ontario tax |
|---|---|---|---|
| $100,000 | $5,947 | $26 | 0.4% |
| $130,000 | $9,116 | $1,261 | 13.8% |
| $200,000 | $17,417 | $5,909 | 33.9% |
| $250,000 | $23,785 | $9,476 | 39.8% |
Once both parts apply, Ontario’s 11.16% bracket behaves like 17.41%, and the 13.16% top rate like 20.53%.
What is take-home pay on typical Ontario salaries?
These examples use Ontario pay levels from Statistics Canada rather than round numbers: $25,000 for part-time or entry-level work, the Ontario median employment income of $46,100 (2024 Canadian Income Survey), the annualized average weekly earnings from above, and $130,000 for a surtax-paying professional. Each is an employee with one employer and no RRSP deduction.
| Line | $25,000 | $46,100 | $72,342 | $130,000 |
|---|---|---|---|---|
| Basic Ontario tax | $521 | $1,506 | $3,462 | $9,116 |
| Ontario surtax | $0 | $0 | $0 | $1,261 |
| Ontario Health Premium | $287 | $450 | $600 | $750 |
| Premium and surtax as a share of the Ontario bill | 35.5% | 23.0% | 14.8% | 18.1% |
| Federal tax | $750 | $3,481 | $7,737 | $20,102 |
| Total income tax | $1,559 | $5,437 | $11,799 | $31,229 |
| CPP, CPP2 and EI | $1,687 | $3,286 | $5,219 | $5,770 |
| Take-home pay | $21,754 | $37,377 | $55,324 | $93,002 |
| Monthly | $1,813 | $3,115 | $4,610 | $7,750 |
| Marginal rate | 25.05% | 19.05% | 29.65% | 43.41% |
The lowest salary carries the highest premium share: at $25,000 the premium is over a third of the Ontario bill, and its marginal rate is also higher than the median earner’s. The average salary in Canada guide explains the Statistics Canada measures behind these pay levels.
How does Ontario compare with Quebec and Manitoba?
Running the same four salaries through the calculator for Ontario’s two neighbours gives:
| Salary | Ontario take-home | Manitoba take-home | Quebec take-home (approximate) | Ontario minus Manitoba | Ontario minus Quebec |
|---|---|---|---|---|---|
| $25,000 | $21,754 | $21,749 | $21,876 | $5 | −$122 |
| $46,100 | $37,377 | $36,414 | $36,169 | $964 | $1,208 |
| $72,342 | $55,324 | $53,360 | $52,407 | $1,964 | $2,917 |
| $130,000 | $93,002 | $89,477 | $87,301 | $3,525 | $5,701 |
At $25,000 the three land within about $127 of each other, and Quebec’s large $18,952 basic personal amount together with the 16.5% abatement puts it slightly ahead; this is also where Ontario’s premium phase-in bites. From the median salary upward Ontario pulls clearly ahead, because Manitoba’s 10.8% and 12.75% rates and Quebec’s 14% and 19% rates are far above Ontario’s 5.05% and 9.15%. Manitoba’s thresholds are frozen rather than indexed, which tends to widen its gap as wages rise. At $130,000 the Ontario and Manitoba marginal rates are almost identical (43.41% against 43.4%) because the surtax lifts Ontario’s.
Does an RRSP deduction save more in Ontario?
In the phase-in zones it does, because a deduction removes premium as well as bracket tax. From the worked examples:
- At $25,000, a $3,000 deduction saves $752, or 25.05%, of which $180 is health premium.
- At the median $46,100, a $5,000 deduction saves $953, the plain 19.05%, since taxable income stays inside a flat premium band.
- At $130,000, the same deduction saves $2,170, including $312 of surtax.
Someone whose taxable income lands between $72,000 and $72,600 can get back up to $150 of premium with a small deduction. The RRSP contribution limit guide explains how much room you have.
What do Ontario salary estimates most often get wrong?
- Leaving out the premium. Salary tools built around other provinces skip it, understating Ontario tax by up to $900 a year.
- Reading “20% surtax” as 20% more tax on pay. It applies to basic Ontario tax above $5,818, not to salary.
- Expecting the Ontario tax reduction to cover the premium. It cannot; the premium is charged in full.
- Counting the Ontario Trillium Benefit as a refund. It is a separate monthly benefit; see the Ontario Trillium Benefit guide.
- Converting an hourly wage by guesswork. The hourly to salary calculator does it properly, and the Ontario minimum wage guide has the current floor.
When should an Ontario filer get tax help?
Ontario-specific situations are the usual reason: claiming the Ontario tax reduction for several dependants, a mid-year move into or out of Ontario, split income that attracts the health premium, or a surtax-level income with stock options or rental property. A tax professional or certified software working from actual slips will handle those. This calculator is an education tool; the CRA’s notice of assessment is the final word, and the 2026 tax brackets guide sets Ontario’s rates beside every other province.
