Example how tax is calculated in Canada
Let’s say you have $120,000 of taxable income in 2025:
Federal Tax
- First $57,375 at 14.5% = $8,325.88
- Next $57,375 ($114,750 – $57,375) at 20.5% = $11,761.88
- Remaining $5,250 ($120,000 – $114,750) at 26% = $1,365.00
Total Federal Tax ≈ $21,452.76
Ontario Tax
- First $52,886 at 5.05% = $2,670.08
- Next $52,889 ($105,775 – $52,886) at 9.15% = $4,839.36
- Remaining $14,225 ($120,000 – $105,775) at 11.16% = $1,587.96
Total Ontario Tax ≈ $9,097.40
Combined Total
- Federal: $21,452.76
- Provincial: $9,097.40
- Grand Total Tax ≈ $30,550.16
- Average effective tax rate ≈ 25.5%
Meanwhile, your marginal tax rate (on the last dollar earned) would be around 26% (federal) + 11.16% (provincial) ≈ 37.16%.
Tax credits and benefit for individuals in Canada
Once tax is calculated on your taxable income, tax credits are applied, which reduces the amount of tax payable. Most tax credits are calculated at 15%, which directly reduce the amount of tax payable.
Total tax payable – (Tax credits X rate) = Final tax payable
There is various tax credit available to individuals. Some are non-refundable, are while others are refundable. Non-refundable means, the credit will be lost if cannot be used because your tax payable is less than the non-refundable credit. Refundable tax credits, on the other hand, are paid out to you if your tax payable is less than the total of your non-refundable and refundable credits.
Non-refundable credits
None-refund able credits are categorized into two types: personal non-refundable tax credits and expense-based non-refundable tax credits.

For example,
Facts
You (the taxpayer): Net income = $60,000
Medical expenses = $2,000
Your dependant (mother, age 70):
Net income = $18,000
Medical expenses = $5,000
She qualifies as your dependant under CRA rules.
Step 1: Calculate your own claim
- Threshold for you: lesser of 3% of net income ($60,000 × 3% = $1,800) or $2,759 → $1,800
- Eligible amount: $2,000 − $1,800 = $200
- Federal tax credit: $200 × 15% = $30
Step 2: Calculate claim for your dependent (mother)
- Threshold for your mother: 3% of her net income ($18,000 × 3% = $540)
- Eligible amount: $5,000 − $540 = $4,460
- Federal tax credit: $4,460 × 15% = $669
Step 3: Total credit
- Your claim: $30
- Dependent claim: $669
- Total federal credit = $699
TIPS: Since it is an income tested credit, it is a good idea to combine all family medical expenses and claim under low-income spouse.
The most common medical expense you can claim:
- Prescription drugs
- Dental services
- Certain medical devices (hearing aids, CPAP machines, insulin pumps, etc.)
- Premiums paid for private health insurance plans
