Taxable Income
Revenu imposable in French
Quick definition
Taxable income is the amount your tax brackets actually apply to: total income minus deductions, reported on line 26000 of your return. It is usually well below your gross pay, which is why deductions are so valuable.
The number the brackets actually use
Your salary is not what gets taxed. The tax bracket rates apply to taxable income, a figure you build in stages on your tax return, and every dollar of deduction you claim removes a dollar from it before the brackets ever see it.
The waterfall: total, net, taxable
The return works like a waterfall with three pools, each one smaller than the last.
- Total income gathers everything the tax system counts: employment and self-employment income, interest, grossed-up dividends (see the dividend tax credit), the taxable 50% of capital gains (as of July 2026, see capital gains tax), RRSP and RRIF withdrawals, EI benefits, and CPP and OAS pensions.
- Minus deductions such as RRSP and FHSA contributions, childcare expenses, union dues and eligible moving expenses equals net income, line 23600.
- Minus a few further deductions, such as net capital losses carried over from other years and the northern residents deduction, equals taxable income, line 26000.
Net vs taxable: the distinction that bites
For most people the two bottom pools hold the same number, but they do different jobs. Net income (line 23600) is what the government uses to income-test benefits: the OAS clawback, the GIS, the Canada Child Benefit, the GST/HST credit and many provincial programs all phase out based on it. Taxable income (line 26000) is what the brackets tax.
The subtlety: a deduction taken between the two lines, like a capital loss carried forward, lowers your tax but does nothing for your benefits, while a deduction above the net-income line, like an RRSP contribution, does both. For a retiree hovering near the clawback threshold, where a deduction sits on the return is worth real money.
What is not income at all
Some money never enters the waterfall in the first place:
- TFSA withdrawals and all growth earned inside the account
- the gain on the sale of your principal residence
- gifts and inheritances
- lottery winnings and most other windfalls
Deductions vs credits, in one line
A deduction shrinks taxable income and saves tax at your marginal rate; a credit reduces the tax itself, usually at the lowest rate. The difference is bigger than it sounds: see tax credit vs deduction.
In Canada
Québec residents build the same waterfall a second time on the provincial TP-1 return, under Revenu Québec's own deduction rules, so federal and Québec taxable income can differ for the same person. In every other province, provincial tax simply applies its own brackets to the taxable income from the federal return. Our Tax Calculator starts from gross income, applies your RRSP contribution and other deductions, and taxes the resulting taxable income.
Worked example
Amir earns a $95,000 salary and $2,000 of interest in 2026, so his total income is $97,000. He contributes $10,000 to his RRSP and deducts it. His net income is $87,000 on line 23600, and with no further deductions his taxable income on line 26000 is also $87,000. The brackets tax $87,000, not $97,000: the RRSP deduction removed $10,000 from the top of his income, where his marginal rate is highest, and every income-tested benefit now sees $87,000 as well.
