Legal, CRA-approved strategies to keep more of your money this tax season
Canada has among the highest personal income tax rates in the developed world when federal and provincial taxes are combined. A professional in Ontario earning $150,000 pays an effective combined tax rate of approximately 38 to 43%. Yet most Canadians claim only a fraction of the deductions and credits available to them.
CRA statistics show that Canadians collectively leave billions of dollars in unclaimed deductions and credits on the table each year. These 25 tips represent the highest-impact, most commonly missed strategies for 2025.
RRSP contributions reduce your taxable income dollar for dollar. Contributing $15,000 at a 43% marginal rate saves $6,450 in taxes immediately. The 2025 filing deadline for 2024 contributions was March 3, 2025 — but 2025 contributions (up to 18% of 2024 earned income) can be made anytime.
All investment growth inside a TFSA is permanently tax-free. The 2025 contribution limit is $7,000. Cumulative room for those eligible since 2009 is $95,000. Never hold high-growth or high-dividend assets in a non-registered account when TFSA room is available.
Contribute to a Spousal RRSP if you earn significantly more than your spouse. The contributor gets the deduction now at their higher rate; the lower-earning spouse withdraws in retirement at their lower rate. Massive long-term tax savings for unequal-income couples.
New since 2023. Contribute up to $8,000/year ($40,000 lifetime). Contributions are tax-deductible like RRSP. Withdrawals for a qualifying home purchase are tax-free like TFSA. Double benefit — best of both worlds for first-time buyers.
Check your MyAccount on the CRA website for your exact RRSP room including carry-forwards from prior years. Many Canadians have significant unused room accumulated from lower-income periods. A bonus or windfall year is the ideal time to make a large catch-up contribution.
If you work from home and your employer provides a T2200, you can deduct a portion of rent/mortgage interest, utilities, internet, and office supplies proportional to your workspace. See our Home Office Deduction Calculator for the exact calculation.
If you use your personal vehicle for work (excluding commuting), keep a CRA-compliant mileage log. Deduct the business-use percentage of all vehicle expenses, or use the simplified per-km rate of $0.72/km for the first 5,000 km (2025 rate). See Vehicle Expense Deduction Guide.
All union dues and professional membership fees required for employment are 100% deductible. These flow through on your T4 (Box 44) and are automatically included in your return if you file electronically — but verify the amount matches your receipts.
If you moved 40km+ closer to a new job or school, you can deduct eligible moving expenses on Form T1-M. This includes movers, travel costs, temporary accommodation, and more. See Moving Expense Deduction Guide.
Employed tradespeople and apprentice mechanics can deduct eligible tool costs. The deduction equals the cost of tools minus a threshold amount ($1,257 for 2024). Apprentice mechanics have enhanced deductions for new tools purchased.
Claim up to $8,000 for children under 7, $5,000 for ages 7–16. Typically claimed by the lower-earning spouse. Includes daycare, babysitters, day camps, and overnight camps (with limits). See Childcare Deduction Guide.
Students can claim a 15% federal credit on all eligible tuition fees. Unused amounts can be carried forward indefinitely or transferred (up to $5,000) to a supporting parent, grandparent, or spouse. See Tuition Tax Credit Guide.
Claim a 15% federal tax credit on NSLSC or provincial student loan interest paid. This credit can be carried forward 5 years — useful if you're in a lower tax bracket while repaying loans. See Student Loan Interest Credit Guide.
Not a deduction, but the Canada Education Savings Grant adds 20% on the first $2,500 contributed per child per year (up to $500/year, $7,200 lifetime). It's a guaranteed 20% instant return. Room carries forward — contribute to catch up on prior years.
A significant non-refundable credit for Canadians with severe and prolonged disabilities. The 2024 federal credit equals $9,428 × 15% = $1,414 in federal tax savings. Can be transferred to a supporting family member if the person with disability has insufficient income.
15% federal credit on first $200, 29% on amounts above $200 (33% if taxable income exceeds $246,752). Plus provincial credits of 5–24%. Combined, donations above $200 can generate a 40–53% tax credit. See Donation Tax Credit Calculator.
Donating publicly listed securities (stocks, ETFs) directly to a registered charity completely eliminates the capital gains tax on the donation AND generates the full donation receipt. This is one of the most powerful tax strategies for investors with large unrealized gains.
Federal political contributions receive extremely generous credits: 75% on first $400, 50% on next $350, 33.3% on next $525. Maximum credit $650. See Political Donation Credit Guide.
Sell investments with unrealized losses before December 31 to offset capital gains elsewhere in your portfolio. The 30-day superficial loss rule prevents repurchasing the same security immediately — but you can buy a similar ETF (e.g., sell VFV, buy XEQT) to maintain market exposure.
In 2024, the federal government proposed increasing the capital gains inclusion rate to 2/3 for gains over $250,000 (individuals). Plan dispositions accordingly — spread large gains across tax years, or realize them before threshold increases take effect.
For qualified small business shares and farm/fishing properties, the first $1.25 million in capital gains is exempt from tax (2024 LCGE). This is a massive benefit for small business owners planning an eventual sale.
Once revenue exceeds $30,000 in any four consecutive quarters, registration is mandatory. However, voluntary early registration lets you claim ITCs (input tax credits) on business expenses — potentially recovering thousands in taxes paid on equipment and supplies.
Self-employed Canadians can deduct home office expenses using the business-use percentage (workspace sq ft ÷ total home sq ft). Unlike employed workers, self-employed can deduct mortgage interest and CCA on the home, not just rent and utilities.
The optimal split between salary and dividends depends on income level, RRSP room, eligible vs non-eligible dividends, and provincial rules. See our Salary vs Dividends Calculator.
If family members genuinely work in your business, paying them market-rate salaries shifts income to lower-earning family members who pay less tax. CRA requires that the salary be reasonable and that actual services be performed — keep documentation.
