What Are Tax Deductions?
Tax deductions are expenses that you can subtract from your taxable income, thereby reducing the amount of income that is subject to tax. Deductions are different from tax credits, which directly reduce the amount of tax you owe.
Example: If you have $50,000 in taxable income and $10,000 in eligible deductions, your taxable income becomes $40,000.
Common Ontario Tax Deductions
Ontario offers several common deductions, including:
- Medical expenses exceeding 3% of your net income
- Donations to registered charities
- Home office expenses
- Union dues
- Educational expenses for yourself or dependents
How Deductions Work in Ontario
To claim a deduction, you must have proper documentation and ensure the expense is eligible. The Canada Revenue Agency (CRA) provides detailed guidelines on which expenses qualify.
Formula: Taxable Income = Gross Income - Deductions
Limitations and Considerations
Not all expenses qualify as deductions. Some common limitations include:
- Personal expenses (e.g., groceries, entertainment)
- Expenses not directly related to your work or business
- Expenses that exceed the CRA's guidelines
