How to save tax while investing in Canada

Earning a $100,000 annual salary in Canada is a fantastic milestone, but it also brings a noticeable shift in your finances: tax brackets start to bite harder. At this income level, you cross out of the lower tiers and find yourself facing a combined federal and provincial marginal tax rate of roughly 30.5% to 40% (depending on your province).

This means that for every extra dollar you earn over the threshold, up to 40 cents goes straight to taxes. However, it also means that every dollar you deduct from your income saves you up to 40 cents. By strategically utilizing registered accounts, an average Canadian earning $100k can legally wipe thousands of dollars off their annual tax bill.

Use our interactive calculator below to see how adjusting your contributions to a Registered Retirement Savings Plan (RRSP) and a First Home Savings Account (FHSA) can lower your estimated tax due in real time:

The Pillars of the $100k Tax Strategy

1. The RRSP (Registered Retirement Savings Plan)

For someone making $100,000, your maximum annual RRSP contribution room is 18% of your earned income from the previous year (up to a dynamic yearly maximum). If you maximize this room, you drop your taxable income significantly. Because your highest dollars are taxed at your marginal rate, a substantial chunk of what you contribute comes right back to you as a tax refund in the spring.

2. The FHSA (First Home Savings Account)

If you don't own a home yet, the FHSA is arguably the most powerful account in Canada. It allows you to deduct up to $8,000 per year directly from your income—just like an RRSP. However, unlike an RRSP, when you withdraw the money to buy your first home, the gains and withdrawals are completely tax-free. It is a dual-threat tool that every middle-to-high earner should evaluate.

The Takeaway

The difference between letting your income sit fully exposed to standard payroll taxes and actively using registered shelters can amount to $3,000 to $5,000 in found money every single year. When it comes to personal finance, optimizing your tax burden is one of those foundational things which matter.
