How to Calculate Tax Deductions Ontario

Calculating tax deductions in Ontario can help you maximize your refund and reduce your taxable income. This guide explains the types of deductions available, how to claim them, and provides a calculator to estimate your potential savings.

What Are Tax Deductions?

Tax deductions are expenses that you can subtract from your taxable income, reducing the amount of tax you owe. In Ontario, deductions can come from various sources, including work-related expenses, charitable donations, and home-related costs.

Deductions differ from tax credits, which directly reduce the amount of tax you owe without affecting your taxable income. Understanding the difference is crucial for effective tax planning.
