Legal strategies to reduce your family's tax bill — deductions, credits, income splitting, and registered account optimization.
Canadian families pay significant taxes, but there are many legitimate strategies to reduce your tax burden. From child care expense deductions to spousal RRSPs and pension splitting, family tax planning can save thousands of dollars annually. Here are the most important strategies for Canadian families in 2025.
The child care expense deduction is one of the most valuable for families with young children. The lower-income spouse claims eligible childcare expenses paid for children under 16 (or any age if the child has a disability).
| Child's Situation | Annual Deduction Limit |
|---|---|
| Under age 7 | $8,000 per child |
| Age 7–16 | $5,000 per child |
| Any age with severe disability | $11,000 per child |
Eligible expenses include daycare, nursery school, day camps, overnight camps (limited), and nannies/babysitters. Keep all receipts and get SIN numbers from caregivers who are individuals.
If you moved at least 40km closer to a new job or business location, eligible moving expenses are deductible. Families relocating for employment can deduct moving truck costs, temporary accommodation, house hunting trips, and real estate commissions on the sale of the old home.
RRSP contributions reduce your taxable income dollar-for-dollar. For families with income disparities, spousal RRSP contributions by the higher-income spouse reduce their tax now and shift retirement income to the lower-income spouse later.
| Credit | Amount (2025 approx.) | Notes |
|---|---|---|
| Basic Personal Amount | $15,705 (federal) | Everyone gets this |
| Spouse/Common-Law Partner Amount | Up to $15,705 | If spouse has no/low income |
| Canada Caregiver Credit | Up to $7,999 | For infirm dependants |
| Disability Tax Credit | $9,872 federal base | For those with severe disabilities |
| Adoption Expense Credit | Up to $18,210 | For eligible adoption expenses |
| Medical Expense Tax Credit | Expenses over 3% of net income | Can claim for whole family |
The CCB is income-tested — the higher your family net income, the lower your CCB. This creates an incentive to reduce net income through RRSP contributions, child care deductions, and other deductions. A family whose net income is $5,000 above a CCB phase-out threshold may gain $500–$1,000 in additional annual CCB by making RRSP contributions that reduce net income below the threshold.
Canada significantly restricted income splitting for families with the 2014 Tax on Split Income (TOSI) rules. However, several legitimate strategies remain:
The higher-income spouse contributes to a spousal RRSP, using their own deduction room. After a 3-year attribution period, the lower-income spouse withdraws the funds at their lower tax rate. Best used when there will be a significant income disparity in retirement.
Eligible pension income (defined benefit pensions, annuities, RRIF withdrawals after age 65) can be split up to 50/50 between spouses on the tax return. No actual money movement required — it's a paper election on Schedule 2. Can save thousands annually for couples with large pension income disparities.
The higher-income spouse pays household expenses so the lower-income spouse can invest their income. The attribution rules track investment income, not cash flow — paying your spouse's bills so they can invest doesn't trigger attribution on the investment returns.
Lower-income family members (including adult children) can realize capital gains at their marginal rate rather than the higher-income spouse's rate. Transfer appreciated assets to lower-income family members carefully — attribution rules apply to transfers between spouses, so professional advice is required.
Combine charitable donations from both spouses and claim on the higher-income spouse's return to maximize the federal donation tax credit (29% on amounts over $200, or 33% on amounts over the top federal bracket threshold). Pooling donations provides a higher effective credit rate than splitting them.
Claim all family medical expenses on the return of the lower-income spouse. The 3% net income threshold is lower for the lower-income spouse, so more expenses exceed the threshold and qualify for the credit. Eligible expenses include dental, glasses, prescriptions, private health insurance premiums, certain home renovations for disability, and fertility treatments.
If a family member qualifies for the DTC but can't use the full credit (due to low income), the unused portion can be transferred to a supporting family member. This can save $1,500–$2,500 annually in federal tax for the supporting spouse or parent.
Canadian families save $200-$360/year by switching to KOHO's no-fee account. That's money that could go into your child's RESP instead. Use code 45ET55JSYA for a bonus when you sign up.

Start with the fundamentals: claim childcare expenses, maximize RRSP contributions before the March deadline, optimize who claims which credits, and use spousal RRSPs for retirement income splitting. A family saving $3,000–$5,000 in annual taxes through good planning puts the equivalent of $250–$400/month directly back into their budget.
