As the calendar year draws to a close, families are encouraged to take advantage of various tax-saving strategies that can help optimize their financial situations before the deadline. Financial experts suggest a range of measures, from estate planning reviews to contributions to registered savings plans, that may reduce tax liabilities and secure future benefits.

One key recommendation is to revisit estate planning documents, including wills, beneficiary designations, and letters of wishes, to ensure they remain aligned with current family circumstances and objectives. Careful structuring of assets—such as naming beneficiaries directly on registered investment plans or insurance policies, holding assets jointly with right of survivorship, or utilizing multiple wills to handle different asset types—can help minimize probate fees.

Couples and families with members in lower tax brackets might consider prescribed-rate loans. By loaning funds at the government-set interest rate—currently 3 percent—to a spouse or family trust, investment income can be shifted to those beneficiaries, allowing them to pay tax on earnings instead of the original owner. Such loans require interest payments by June 30 for the prior tax year to avoid attribution rules and must be properly documented before year-end.

Supporting adult family members through Tax-Free Savings Accounts (TFSAs) is another viable option. Money given or loaned interest-free to a spouse or adult child can be contributed to their TFSA, enabling tax-free growth of investments within the account. However, contributors must ensure the recipient has sufficient unused TFSA contribution room to avoid penalties.

For families with children or grandchildren, topping up Registered Education Savings Plans (RESPs) before year-end is advised to maximize eligibility for the Canada Education Savings Grant (CESG), which matches contributions by up to 20 percent to a lifetime maximum of $7,200 per beneficiary. Additionally, timing withdrawals from RESPs can be advantageous if the student has low income and is enrolled in a qualifying postsecondary program.

Childcare expenses also warrant attention. Eligible costs, including daycare, certain camps, and boarding-school fees subject to limits, should be paid before the end of the year to claim relevant federal and provincial tax credits. Maintaining thorough records is essential for accurate filing.

Families caring for a member with disabilities may benefit by establishing or contributing to a Registered Disability Savings Plan (RDSP) before year-end. Contributions can attract significant matching grants through the Canada Disability Savings Grant program, with potential annual matches of up to $3,500 and lifetime grants capped at $70,000. In addition, caregiver tax credits are available for those supporting infirm relatives, though eligibility criteria are complex and require documentation.

Homeowners who have undertaken renovations to add secondary units suitable for seniors or individuals eligible for the disability tax credit might qualify for the multigenerational home renovation tax credit. This federal credit offers 14 percent of eligible expenses up to $50,000, providing a possible refund of up to $7,000. Keeping invoices, contracts, and proof of payment is vital to support claims.

Fertility-treatment expenses, which can represent a substantial financial burden, may also qualify for provincial tax credits depending on the jurisdiction. Families who incurred such costs during the year should organize receipts and relevant documentation to facilitate claims, as rules and limits vary across provinces.

Lastly, individuals anticipating a lower income in the current or upcoming year due to retirement or other reasons might consider making withdrawals from Registered Retirement Savings Plans (RRSPs) or spousal RRSPs before year-end to reduce tax burdens, provided the timing aligns with income changes.

By reviewing these areas ahead of the year-end deadline, families can better position themselves to benefit from available tax credits, deductions, and income-splitting strategies, potentially leading to substantial savings in the coming tax year.
