RRSP or TFSA in Ontario in 2026: what the surtax changes
Ontario has some of the lowest basic tax rates in the country, but a surtax kicks in once provincial tax passes a threshold. The calculator applies it to your income.

In Ontario, 2026 provincial tax starts at 5.05% and rises to 13.16%, with a basic personal amount of $12,989. Those headline rates are not the whole story: a 20% surtax applies to Ontario basic tax above $5,818, and a further 36% above $7,446. In taxable income terms, the first step starts around $94,910 and the second around $111,810. At $130,000, the real marginal rate reaches 43.4%, while adding up the bracket rates gives only 37.2%. For an RRSP contribution, that is good news: every dollar deducted in that zone also saves surtax. For a withdrawal in retirement, it cuts the other way: an Ontario retiree whose income passes those thresholds pays the surtax on RRSP or RRIF withdrawals, not on TFSA withdrawals.
Bracket rates are not the real rate
Ontario's 2026 table has five rates: 5.05%, 9.15%, 11.16%, 12.16%, 13.16%, with thresholds at $53,891, $107,785, $150,000, $220,000. Added to the federal rates, it gives moderate combined rates up to a middle income. Then the surtax comes in. It does not show in the table: you first work out Ontario basic tax, subtract the basic personal credit, then apply 20% and 36% to the parts above $5,818 and $7,446. The amounts come from the 2026 rates page on canada.ca and the T4127 guide.
| Taxable income from | Combined marginal rate |
|---|---|
| $0 | 0.0% |
| $53,891 | 23.1% |
| $58,523 | 29.7% |
| $94,901 | 31.5% |
| $107,785 | 33.9% |
| $111,810 | 37.9% |
| $117,045 | 43.4% |
| $150,000 | 45.0% |
| $181,440 | 48.3% |
| $220,000 | 49.8% |
| $258,482 | 53.5% |
The two rows that match no official threshold are the surtax steps: that is where the rate jumps without the table showing it. At $130,000, for example, you are in Ontario's third bracket and the 26% federal bracket, 37.2% when added up, but the real rate is 43.4%.
What a $10,000 contribution is worth in the surtax zone
At higher incomes, the question is less RRSP or TFSA than the size of the deduction. A large contribution pulls income back under a surtax step, and every dollar taken out of it saves the highest rate.
| Taxable income | Marginal rate | Surtax avoided | Total saved |
|---|---|---|---|
| $100,000 | 31.5% | $93 | $3,058 |
| $115,000 | 37.9% | $340 | $3,450 |
| $130,000 | 43.4% | $625 | $4,341 |
| $160,000 | 45.0% | $681 | $4,497 |

The flip side in retirement
The surtax reaches retirees too. Someone with a workplace pension, CPP and Old Age Security who also draws on a RRIF can end up above the first step. In the calculator's example ($130,000 of income now, $70,000 expected in retirement, $8,000 saved a year for 20 years), the RRSP saves 43.0% and pays only 29.7% on withdrawal, leaving $3,380 more than the TFSA. If retirement income were as high as today's, the gap would vanish. For a well-off retiree, withdrawing earlier and spreading withdrawals out, before pensions stack up, sometimes keeps income out of the surtax zone.
Contribute now, deduct later
An RRSP contribution does not have to be deducted in the year you make it: the undeducted part carries forward, with no time limit, to a year when your income is higher. In Ontario, that carry-forward is worth more than elsewhere. Someone earning $90,000 this year, below the first surtax step, who expects a promotion to $130,000 can contribute now and keep the deduction for the promotion year: it will save 43.4% a dollar instead of 29.7%. Meanwhile, the money grows sheltered from tax inside the RRSP. The same logic applies to a bonus year, a year with a large severance payment or a year when a rental property is sold.
The reverse case matters too. In a year with unusually low income, such as parental leave, a sabbatical or a gap between jobs, the deduction is worth far less, and a TFSA contribution keeps more flexibility.
Modest incomes in Ontario
At the low end, Ontario applies a low-income tax reduction and a health premium that starts at a modest income. The calculator computes neither. Below roughly $30,000 of income, the real saving from an RRSP contribution can therefore differ from the figure shown; that is also the income level where the TFSA nearly always wins, since the tax saved is small.
The Ontario takeaway
Between $60,000 and $94,910 of income, the combined rate stays close to other provinces, and the RRSP or TFSA choice depends mostly on retirement income. Above that, the surtax makes the RRSP more attractive than elsewhere, provided retirement income stays below the same steps. The marginal tax rate calculator shows the federal and provincial split at your income.
