What is the difference between a tax deduction and a tax credit in Canada?

A tax deduction reduces your taxable income — the tax saving depends on your marginal rate. If you are in the 33% bracket and deduct $10,000 (e.g., RRSP contribution), you save $3,300. Higher income earners benefit more from deductions. A tax credit reduces your tax payable directly by a fixed amount, regardless of income. The basic personal amount provides a 15% federal credit on $15,705 — worth approximately $2,350 regardless of what you earn. Some credits are "non-refundable" (reduce tax to zero but not below zero) while "refundable" credits like the GST credit generate a cheque even if you owe no tax. Key deductions: RRSP, childcare, home office, moving expenses. Key credits: basic personal amount, medical expenses, charitable donations.

What are the most commonly missed tax deductions in Canada?

Canadians frequently miss: (1) Home office expenses — if you work from home, even partially, you can claim a portion of rent/utilities/internet using the simplified method ($2/day up to $500) or detailed method (actual expenses × workspace percentage). (2) Carrying charges and investment fees — interest on money borrowed to earn investment income, and some investment management fees in non-registered accounts. (3) Medical expenses — dental, prescription glasses, orthodontics, physiotherapy, and even some home renovation costs for medical purposes. (4) Moving expenses — if you moved 40+ km closer to a new job or school. (5) Union dues and professional fees — fully deductible for employees. (6) Child care expenses — claim on the lower-income spouse's return.

Can I claim rent on my taxes in Canada?

Federal: you cannot deduct rent from your income tax. However, some provinces offer a renter tax credit or property tax credit that partly compensates: Ontario (OEPTC — Ontario Energy and Property Tax Credit includes a component for renters), Manitoba (Education Property Tax Credit), British Columbia (Renter's Tax Credit introduced 2025, up to $400/year), PEI (renters credit), Quebec (solidarity credit). Check your provincial tax return for the applicable credit in your province. Self-employed individuals who work from home can deduct a portion of their rent as a business expense (home office deduction). All renters: your landlord filing their taxes does not let you claim the rent.

How much do medical expenses reduce my taxes in Canada?

The federal Medical Expense Tax Credit (METC) is a 15% non-refundable credit on eligible medical expenses that exceed 3% of your net income (or $2,759 for 2025, whichever is less). Example: $80,000 net income, 3% threshold = $2,400. If you have $5,000 in eligible expenses, the qualifying amount is $5,000 − $2,400 = $2,600. Federal credit: 15% × $2,600 = $390. Plus your province's rate on top (usually 5–10%). Eligible expenses include prescriptions, dental, vision care, physiotherapy, psychologist fees, and many others. Claim on the 12-month period that maximizes the amount — it doesn't have to be the calendar year.
