A $150,000 salary in Ontario leaves $104,320 a year after tax, CPP and EI, which is $8,693 a month. At this pay an RRSP contribution is worth a lot: $10,000 put into an RRSP saves $4,341 in income tax, so the contribution really costs $5,659 of take-home pay.
How much tax does an RRSP save at $150,000 in Ontario?
An RRSP contribution comes off taxable income, so the saving is worked out at the rate on your last dollars of pay. The table shows what each amount does for a single Ontario employee in 2026. The take-home column is what is left after the contribution as well as after tax, CPP and EI.
| RRSP contribution | Tax saved | Share of the contribution saved | Take-home drops by | Take-home after RRSP |
|---|---|---|---|---|
| $2,000 | $868 | 43.4% | $1,132 | $103,188 |
| $5,000 | $2,170 | 43.4% | $2,830 | $101,490 |
| $10,000 | $4,341 | 43.4% | $5,659 | $98,661 |
| $20,000 | $8,682 | 43.4% | $11,318 | $93,002 |
| $33,810 | $14,568 | 43.1% | $19,242 | $85,078 |
Why does the saving run at 43.4%?
Taxable income at this pay is $148,873. That puts you in the 26% federal slice and the 11.16% Ontario slice. Ontario also charges a surtax of 20% and then 36% on its own basic tax once that passes $5,818 and $7,446, and at this income both parts apply. So the 11.16% Ontario rate behaves like 17.4%, and 26% plus 17.4% gives 43.4%.
The rate holds as long as the contribution leaves taxable income above $117,045, where the 26% federal slice starts. A $10,000 contribution leaves $138,873, so it is saved at the full rate. At the 2026 dollar limit of $33,810 the last part of the contribution falls into the 20.5% slice, and the saving is $14,568, or 43.1%. A person who made that full contribution would then be taxed on the next dollar at 37.9%.
What does a $10,000 contribution do to each paycheque?
On a biweekly schedule the normal paycheque is $4,012.30. If $10,000 were taken out evenly over 26 cheques, that is $384.62 a cheque before tax, and with the tax saving the cheque falls to $3,794.65, a drop of $217.66. Monthly take-home goes from $8,693 to $8,222, a drop of $472.
That even pattern only happens if payroll lowers the tax it withholds. If you contribute on your own, the saving usually arrives later as a larger refund, so your cheques shrink by less but your refund grows. Either way the full $10,000 stays yours inside the account.
How does the saving compare across Canada on $150,000?
The same $10,000 saves different amounts in different provinces, because each one has its own rates. This table puts all 13 in order of the tax saved.
| Province or territory | Take-home with no RRSP | Tax saved by $10,000 | Cash cost of $10,000 | Take-home after RRSP |
|---|---|---|---|---|
| Quebec | $98,565 | $4,746 | $5,254 | $93,311 |
| Prince Edward Island | $98,973 | $4,450 | $5,550 | $93,422 |
| Nova Scotia | $98,117 | $4,350 | $5,650 | $92,467 |
| Ontario | $104,320 | $4,341 | $5,659 | $98,661 |
| Manitoba | $100,797 | $4,340 | $5,660 | $95,137 |
| New Brunswick | $101,330 | $4,200 | $5,800 | $95,530 |
| Newfoundland and Labrador | $100,702 | $4,180 | $5,820 | $94,882 |
| British Columbia | $107,377 | $4,032 | $5,968 | $101,409 |
| Saskatchewan | $104,037 | $3,850 | $6,150 | $97,887 |
| Northwest Territories | $107,361 | $3,820 | $6,180 | $101,181 |
| Yukon | $107,797 | $3,690 | $6,310 | $101,487 |
| Alberta | $107,458 | $3,600 | $6,400 | $101,058 |
| Nunavut | $110,408 | $3,500 | $6,500 | $103,908 |
Quebec saves the most at $4,746 and Nunavut the least at $3,500, a gap of $1,246. Ontario is fourth on this list. Quebec saves the most because the tax on its last dollars of pay is the highest of the 13 at this income, 47.46%. Its payroll lines are QPP and QPIP rather than CPP and EI, so compare its take-home with care.
How much RRSP room does a $150,000 salary give?
RRSP room is 18% of the previous year’s earned income, up to the dollar limit, less any pension adjustment from a workplace pension, plus unused room from earlier years. On $150,000 the 18% figure is $27,000, which is under the limits of $33,810 for 2026 and $35,390 for 2027. If your employer has a pension plan, your room will be lower. Your notice of assessment shows your actual number, and the Canada Revenue Agency: contributing to an RRSP page explains the rules.
What could change these numbers?
Before any contribution, income tax on this salary is $39,911, which is 26.6% of pay, and CPP and EI add $5,770. A bonus pushes more of your income into the top slice, other income does the same, and extra credits lower the tax. Money you take out of an RRSP later counts as income that year, so the saving today is repaid at whatever rate applies then. The 2027 federal brackets and CPP figures are not published yet (checked 31 October 2026), so all tax figures here are for 2026.
You can test other amounts in the RRSP calculator or the RRSP tax savings calculator. The same pay without a contribution is covered in the 150k take-home page, nearby pay is on the 140k and 130k pages, and the rates are on the 2026 tax brackets page. For the official slices, see Canada Revenue Agency: Canadian income tax rates for individuals.

Frequently asked questions
How much tax does a $10,000 RRSP save on $150,000 in Ontario?
Our 2026 estimate is $4,341, or 43.4% of the contribution. That makes the cash cost $5,659, and take-home falls from $104,320 to $98,661. The estimate is for a single employee with basic credits only.
Is the saving the same for every dollar I put in?
Not always. At $150,000 it holds at 43.4% until taxable income reaches $117,045. A contribution of $33,810 saves $14,568 in total, slightly under 43.4% of the amount, because the last part falls into a lower federal slice.
Will my paycheque fall by the whole contribution?
Only if the tax saving is not reflected in your cheques. If payroll lowers the tax it withholds, a $10,000 yearly contribution cuts a biweekly cheque by about $217.66 rather than $384.62. Otherwise the saving comes as a refund.
How much RRSP room does a $150,000 salary create?
Room is 18% of earned income up to the dollar limit, so $27,000 on $150,000, before any pension adjustment and plus unused room from earlier years. The limits are $33,810 for 2026 and $35,390 for 2027. Your notice of assessment shows your own room.
What happens to the tax saving when I withdraw the money?
Withdrawals are added to your income in the year you take them out, so the tax saved now is paid back at whatever rate applies then. If your income is lower in retirement, the rate is often lower too, but that depends on your situation.
