Key Ontario Employee Deductions
Ontario offers several deductions that can reduce your taxable income:
- RRSP Contributions: Contributions to a Registered Retirement Savings Plan.
- Union Dues: Dues paid to a recognized union.
- Charitable Donations: Donations to registered charities.
- Medical Expenses: Eligible medical expenses over 3% of income.
- Home Office Deduction: Expenses for a home office.
Note: Not all deductions are eligible for all taxpayers. Some may have income limits or other restrictions.
How Deductions Work
Deductions reduce your taxable income, which can lower your tax liability. The formula for calculating taxable income is:
Taxable Income = Gross Income - Total Deductions
Once you have your taxable income, you can calculate your estimated tax using Ontario's progressive tax rates.
| Taxable Income | Tax Rate |
|---|---|
| $0 - $45,142 | 5.05% |
| $45,142 - $90,287 | 9.15% |
| $90,287 - $102,703 | 11.16% |
| $102,703 - $220,000 | 12.16% |
| Over $220,000 | 13.16% |
Worked Example
Let's say you have a gross income of $60,000 and you contribute $5,000 to your RRSP. Here's how the calculation works:
- Taxable Income = $60,000 - $5,000 = $55,000
- Tax on first $45,142 = $45,142 × 5.05% = $2,284.27
- Tax on next $9,858 = $9,858 × 9.15% = $899.56
- Total Tax = $2,284.27 + $899.56 = $3,183.83
- Tax Savings = Original tax on $60,000 - New tax on $55,000 = $3,450 - $3,183.83 = $266.17
In this example, your RRSP contribution saves you $266.17 in taxes.
