Taxes aren’t fun for most people, I know, my own circle consists of family and friends that actually look for me every year to do their taxes… (yes, I enjoy it this much!) but you know what, Taxes are one of the biggest expenses we face. The good news is that, unlike your rent or your phone bill, you actually can reduce this one if you know how the system works.
Now, I’ll admit: I genuinely enjoy doing my taxes. I find tax law weirdly fascinating, not because I like paperwork, but because I love uncovering hidden advantages. Over the years, I’ve found a few underrated tax moves that most Canadians either overlook or misunderstand.
These aren’t shady loopholes. They’re legal blind spots built into the system — and if you use them right, they can quietly save (or earn) you thousands over time.
Let’s dig in.
1. The RRSP Refund Reinvestment Loop
Most people contribute to their RRSP and stop there. But the real strategy? Reinvest your tax refund.
Here’s how it works:
- You contribute to your RRSP, say $5,000
- You get a tax refund of ~$1,000 (depending on your bracket)
- Instead of spending it, you reinvest that refund, ideally back into your RRSP or your TFSA, or simply put it into your brokerage margin account
Do that every year for 10+ years and you’re essentially turning each dollar of RRSP contribution into more than just retirement saving, it becomes a compounding engine.
I treat my RRSP like a boomerang. The money goes in, comes back in the form of a refund, and then I throw it back into another wealth-building bucket.
(Pro tip: If you haven’t decided whether to use RRSP or TFSA first, read my TFSA vs RRSP guide, it’ll help you choose smarter)
2. Carrying Capital Losses Forward
Had a bad year in the market? Don’t let those losses go to waste!
If you sell an investment at a loss (like a dip in crypto or stocks), you can use that capital loss to offset capital gains in future years. And not just next year: you can carry those losses forward indefinitely.
Learn more about capital gains and how they differ from dividends here.
It’s basically a credit you can hold onto until you need it. I harvested losses in 2017, and in 2022 and I’m still using them to reduce tax owed on recent gains.
Most people forget to report these or think losses are just, well, losses. But in tax terms, they’re a future asset.
3. Claiming Home Office Expenses (Even Part-Time)
If you work from home, even partially, you can likely claim some portion of your:
- Rent or mortgage interest
- Utilities (heat, electricity, water)
- Internet and phone
- Office supplies
Whether you’re salaried and remote, a side hustler, or full-time self-employed, there’s probably a version of the home office deduction that applies to you.
No, it won’t make you rich and it’s a bit boring to fill the forms with all the size of your house, the square feets you use for office space, etc. But it adds up.
For me, it’s less about giant deductions and more about stacking small ones consistently. That mindset has easily saved me hundreds each year — for expenses I already had.
And if you’re fully self-employed, stay tuned for my upcoming Self-Employed Tax Checklist — it’s in the works.
4. The Spousal RRSP Advantage
If you earn more than your partner, the Spousal RRSP is one of the most overlooked tax planning tools out there.
Here’s the idea:
- You contribute to a Spousal RRSP in your partner’s name
- You get the deduction today
- Later, when they withdraw in retirement, it’s taxed at their rate (which may be lower)
This is a smart way to income-split and smooth out your household tax burden over time. Most couples I know skip this because they think RRSPs are solo accounts. But the Spousal RRSP is built into the rules — it’s just underused.
5. The TFSA Is More Than Just a Savings Account
Way too many people use their TFSA like a piggy bank — a place to stash cash “just in case.” But the real value of the TFSA comes when you treat it like an investment shelter. You can hold stocks, ETFs, REITs, and more and all the growth is tax-free, forever.
That means if your investments double inside a TFSA, you don’t owe a cent. No capital gains, no dividend taxes, no reporting headaches, nothing, just withdraw your money and enjoy!
If you’re only using your TFSA for savings, you’re missing the magic. It’s one of the best legal tax shelters we have.
It’s Not Cheating to Understand the Rules
Look, I get that taxes can feel like a chore. But this system isn’t out to get you, it just takes from everyone to pay for our “common life expenses” as a society and rewards people who take the time to understand it.
It’s not cheating to learn how to optimize. It’s smart. The CRA literally gives us these tools and even explains how to use them, we just have act.
So here’s my challenge to you:
Pick one of these five moves, and set it in motion… this week, no delays. Tax optimization is like investing: the earlier you start, the more freedom you buy.
