Carrying Charges & Interest Expenses Canada 2026

Let's face it — investing isn't cheap. Between management fees, interest on investment loans, and those endless charges that nibble away at your returns, it can feel like death by a thousand cuts. But here's the thing: the CRA actually lets you deduct many of these carrying charges and interest expenses on your tax return. That means more money back in your pocket and less flowing to Ottawa.

What Exactly Are Carrying Charges?

In plain English? Carrying charges are the costs you pay to "carry" or hold your investments. Think of them as the price of doing business in the investment world. The CRA specifically allows deductions for these expenses because, well, they're considered necessary to earn investment income. But here's where it gets a bit murky — not every fee with a fancy name makes the cut.

The income tax act has some pretty specific rules about what qualifies. And trust me, the CRA loves to audit these deductions, so you'd better have your ducks in a row with proper documentation and a clear paper trail tracing your borrowed funds to eligible investments.

What You CAN Deduct (The Good News)

What You CANNOT Deduct (The Bad News)

Before you get too excited and start trying to deduct everything under the sun, let's pump the brakes. The CRA has a strict "nope" list, and claiming these will land you in hot water faster than you can say "audit."

• Interest on money borrowed for RRSPs, TFSAs, RESPs, FHSAs, or other registered plans
• Brokerage fees or commissions when buying/selling securities (these reduce your capital gains instead)
• Safety deposit box charges (even if you store investment certificates there)
• Student loan interest (claim this as a credit on line 31900 instead)
• Subscription fees for financial newspapers, magazines, or newsletters
• General financial planning fees (unless part of an investment management fee)
• Legal fees for divorce or custody battles

The "Reasonable Expectation of Income" Rule

Here's where the CRA gets picky. You can't just borrow money to buy any old stock and expect to deduct the interest. Your investment must have a reasonable expectation of income — meaning it should pay interest or dividends. If the only potential return is capital gains, you're out of luck.

But don't panic if your stocks aren't currently paying dividends. The CRA generally accepts that common shares might pay dividends in the future. However, if a company has a stated policy of never paying dividends (looking at you, certain tech giants), then borrowing to buy those shares won't give you a deduction. The infamous Swirsky v. The Queen case taught us that lesson the hard way.

How to Claim Your Deductions

Ready to get your money back? Here's the play-by-play:

• Claim your total carrying charges and interest expenses on line 22100 of your personal tax return
• Complete Schedule 4 (federal) if you have both Canadian and foreign investment income
• For Quebec residents, report on Schedule N instead
• Keep all receipts, statements, and documentation — the CRA might ask for them later
• Don't reduce your investment's adjusted cost base with these expenses (that's a common mistake)

These deductions reduce your taxable income dollar-for-dollar, which could bump you into a lower tax bracket. Speaking of which, understanding Canada's tax brackets helps you see the full impact of these deductions.

The Disappearing Source Rule (When Things Go Sideways)

What happens if your investment tanks and you sell it at a loss? Good news — the disappearing source rules might let you continue deducting interest on the remaining loan balance. This is a bit of a silver lining when your leveraged investment doesn't pan out. The key is that you used the proceeds to pay down the associated debt.

But here's the nuance: this only applies if you actually dispose of the investment. If you're just holding a losing position hoping for a rebound, you can still deduct the interest as long as the original reasonable expectation of income existed.

Compound Interest Deductions

Here's a hidden gem many Canadians miss: compound interest on investment loans is also deductible under Section 20(1)(d) of the Income Tax Act. If you borrow money to pay the interest on your investment loan (yes, borrowing to pay interest on borrowed money), that second loan's interest can be deductible too. It's like tax deduction inception, but completely legit.

However, the CRA is watching this closely. You need to maintain immaculate records showing the trail of funds from each loan to its eligible use. One misstep and the whole deduction house of cards could come tumbling down.
