Most people think about taxes in April, which is exactly the wrong month to be thinking about them. By the time you're staring at a return in the spring, the year that produced it is already locked in. Nothing you do in April changes what happened in the twelve months before it. The window where you can actually change the outcome closes on December 31, and most Canadians let it shut without doing anything.
Year end tax planning isn't about finding some clever loophole. It's about using the tools already sitting in front of you, RRSP room, TFSA room, capital losses, charitable giving, before the calendar runs out and those opportunities reset or disappear. A few decisions made in November or early December can shift what you owe by a noticeable amount, and they cost nothing but a bit of attention.
Why the Last Few Weeks of the Year Matter So Much
Tax planning year end works differently than tax filing. Filing is documentation. Planning is action, and action has deadlines that don't bend. A TFSA contribution made on January 2 instead of December 30 is a contribution for the wrong year. A capital loss triggered after the market's last trading day of December doesn't offset this year's gains at all. Pre year end tax planning exists precisely because so many of these choices are irreversible once the calendar flips.
The businesses and individuals who do this well don't wait until the second week of December to start. They look at where their income landed, where it's likely to land next year, and make a handful of targeted moves while there's still time for the paperwork to settle.
Year End Tax Planning for Individuals
For most individuals, the checklist is shorter than people expect, but the order matters.
Top up your TFSA before December 31 if you have the room. The 2026 annual limit sits at $7,000, and if you've never contributed and have been eligible since 2009, your cumulative room could be well over $100,000. Unlike an RRSP, a TFSA follows the strict calendar year with no grace period into the new year.
RRSP contributions are more flexible. Anything contributed by the deadline in early the following year can still be claimed against this year's income, but making the contribution before December 31 rather than waiting until the last minute avoids the usual scramble and lets you see your actual taxable income sooner, which matters if you're trying to stay under a specific bracket threshold.
If you're sitting on investments with unrealized losses, this is the window to consider selling them to offset capital gains realized earlier in the year. Trade settlement takes a couple of business days, so this needs to happen well before the market's last session of December, not on the 31st itself.
Charitable donations, medical expenses, and childcare costs all need to be paid, not just pledged, before year end to count for the current tax year. A pledge card from a fundraiser in November means nothing if the actual payment doesn't clear until January.
Year End Tax Planning for Small Business Owners
Year end tax planning for small business owners carries an extra layer, because decisions here affect both personal and corporate tax positions at the same time.
Salary versus dividend timing is worth revisiting every year, not just once when the business was incorporated. Paying yourself a bonus or salary top-up before the corporate year end can shift income between the corporation and your personal return in a way that reduces the combined tax bill, depending on where each side of that equation currently sits.
If you're planning to buy equipment, vehicles, or other capital assets the business needs anyway, doing it before your corporate year end rather than after can accelerate the capital cost allowance you're able to claim. It's not a reason to buy something you don't need, but if the purchase was already planned for early next year, moving it up a few weeks can matter.
Review your accounts receivable for anything genuinely uncollectible. Writing off bad debts before year end, rather than carrying them as an asset that will never actually convert to cash, keeps your books and your tax position more accurate.
End-of-Year Investment and Financial Planning Moves
Year end financial planning tips tend to overlap heavily with tax planning, since so much of what drives your tax bill comes from how your investments are structured. Rebalancing a portfolio before year end, rather than in the new year, lets you factor any resulting gains or losses into this year's numbers rather than pushing the decision, and its tax consequences, into the next twelve months.
Year end investment planning also means checking whether income splitting with a spouse through a spousal RRSP or prescribed rate loan still makes sense given how each of your incomes has shifted over the year. What made sense two years ago doesn't always still apply.
A Few Mistakes That Show Up Every Year
The most common one is treating December 31 as a soft deadline. It isn't. Trades need to settle, contributions need to clear, and payments need to actually leave your account, not just get scheduled, before the calendar year ends.
The second is doing this work in isolation. A move that makes sense for your personal return might create a problem on the corporate side, or vice versa, if nobody looks at both together.
Where a Second Set of Eyes Helps
End of year tax planning strategies tend to work best when someone who actually knows your full financial picture reviews them together, rather than each decision getting made on its own without checking how it interacts with the rest. At Mehra CPA, this is where we spend most of our November and December client conversations, going through RRSP and TFSA room, corporate year end timing, and income splitting opportunities together so nothing gets left on the table simply because nobody connected the dots before the deadline passed. If your year end is approaching and you haven't looked at any of this yet, there's still time to make it count, but not much.
Year end tax planning rewards the people who start early and act deliberately. The strategies themselves aren't complicated. What separates a lower tax bill from a missed opportunity is usually just whether anyone got around to using the time that was there.
