Five Tax Moves I Made Before December 31 (and What They Saved)

The Year He Stopped Scrambling in April

Marcus Thompson is a forty-five-year-old software developer in Halifax, Nova Scotia, earning around $120,000 a year. For most of his working life, his approach to taxes was to do nothing until April, hand a shoebox of slips to whoever would take it, and accept whatever the result happened to be. The problem with that approach is simple: by the time you file in the spring, almost every move that could have lowered your tax for the previous year is already off the table.

One December he decided to try the opposite. Instead of waiting, he sat down before the calendar turned over and worked through a deliberate year-end checklist. Most of the meaningful tax decisions in Canada have to happen before December 31 to count for that tax year, and he wanted to stop leaving them on the floor.

"The thing nobody tells you," Marcus says, "is that April is for reporting what already happened. December is when you actually get to change the outcome."

How He Worked the Checklist

Marcus used TrackMoola's tax planning hub to walk through his situation move by move, seeing the estimated effect of each one before he acted. The value was not in any single calculation — it was in being able to compare "before" and "after" for each decision and watch the savings accumulate. Here are the five moves he made, what each one is, and roughly what it saved him.

Move One: Topping Up the RRSP

Marcus had unused RRSP room and cash sitting idle, so he made a contribution. The public rule is the one most people know: an RRSP contribution is deducted from your taxable income, and the tax you save depends on your marginal rate. At his income, his top dollars were being taxed at a combined rate in the mid-forties as a percentage, so a meaningful contribution produced a meaningful reduction.

TrackMoola let him see the estimated tax saving from his planned contribution before he transferred a cent. The illustrative saving on this move alone came to roughly $1,900 — the largest single line on his checklist.

Move Two: Tax-Loss Selling

Marcus held a couple of investments in his non-registered account that were worth less than he paid for them. Here the public rule is about capital losses: when you sell an investment for less than its adjusted cost base, you realize a capital loss, and that loss can offset capital gains you realized elsewhere in the year. Because only half of a capital gain is taxable in Canada, the loss works on the same fifty-percent basis.

He had taken some gains earlier in the year, so by deliberately selling the losers before December 31 he cancelled out part of those taxable gains. The illustrative saving here was about $600. He was careful about the rule that prevents you from immediately rebuying the same security to manufacture a loss, and timed things so the loss would actually stick.

Move Three: A Charitable Gift

Marcus already gave to a local food bank, but he had been doing it in dribs and drabs without thinking about timing. Donations to registered charities generate a tax credit, and the credit rate steps up on the portion of annual giving above a modest threshold. By making his planned donation before year-end — and by concentrating it rather than scattering it — he captured the higher-rate credit on more of the gift.

The illustrative saving on his giving came to about $400, on money he was going to donate anyway. Same generosity, better timing.

Move Four: An FHSA Contribution

This was the move Marcus almost skipped because he assumed it did not apply to him. The First Home Savings Account is designed for people saving toward a first home, and it has an unusual double benefit: contributions are deductible like an RRSP, and qualifying withdrawals to buy a first home come out tax-free like a TFSA. Marcus, who had been quietly saving toward a place of his own, opened one and contributed within the annual limit.

The deduction reduced his taxable income at his marginal rate, and TrackMoola showed an illustrative saving of roughly $900 — with the bonus that the money is earmarked for a goal he already had.

Move Five: Timing a Capital Gain

The final move was about restraint rather than action. Marcus had been planning to sell an appreciated investment to free up some cash. Selling it in December would have piled a sizable taxable gain on top of an already strong income year. By choosing instead to wait until early January, the gain would land in the following tax year — and he expected that year to be lighter, because a one-time bonus would not repeat.

Deferring the gain did not erase the tax, but it pushed it into a year where it would likely be taxed more gently, and it kept his current year from being inflated. The illustrative benefit of the timing shift was about $500.

What It Added Up To

Laid out together, the five moves told a clear story. None of them was dramatic on its own. Stacked, they made a real difference.

The combined illustrative saving came to roughly $4,300 — and crucially, almost every dollar of it depended on acting before December 31. By April, the RRSP and FHSA windows for the prior year would be narrow or closed, the losses would be unrealized, and the gain timing would be moot.

"It was the same income and basically the same spending," Marcus says. "The only thing that changed was that I made the decisions in December instead of pretending I had no decisions to make."

A Few Honest Caveats

• Not every move applies to everyone. The FHSA only helps if you qualify as a first-home saver, and tax-loss selling only matters if you have gains to offset.
• Deferring a gain assumes next year really will be lighter — if your income jumps instead, the timing can work against you.
• Charitable credit rates and FHSA and RRSP limits are set by public rules and change over time, so check the current figures.
• The savings on each line depend on your own income and province, which is exactly why seeing your numbers beats copying someone else's checklist.

Try It Yourself

If your tax routine starts and ends in April, you are almost certainly leaving money behind. Before the year closes, walk through your own version of this list in TrackMoola's tax planning hub and see what each move would save in your situation. The point is not to copy Marcus's five — it is to find the handful that apply to you while you still have time to act on them.
