Return of Capital: When a Payment Isn't Income
Part of what a fund pays you can be your own money coming back. What that does to your cost base, when the tax actually lands, and how to tell an ordinary payment from a warning sign.
You own a fund. Every month it pays you something. The yield looks generous, better than your savings account and better than most dividend stocks, and it feels like your money is working.
Then a tax slip turns up in the spring with a number sitting in a box labelled "return of capital," and suddenly you're in a conversation about your cost base that nobody warned you about.
The one-sentence version
Return of capital is when a fund hands you back some of your own money and calls it a distribution.
That's it. Nobody is cheating you, and it doesn't automatically mean something is wrong with what you own. It also isn't free money. You've been handed a withdrawal that arrived looking like a paycheque.
Where your money is coming from
When a fund pays you, that money can come from four different places.
Some of it is interest the fund earned. Some is dividends it collected. Some is capital gains, meaning the fund sold something for more than it paid for it. And some of it can be your own capital, the money you handed over when you bought in.
The first three are income. The fund went out and earned them for you. The fourth one isn't income at all. It's your own money making a round trip back to you.
Every one of them reaches your account looking the same. Same deposit, same date, same feeling of being paid. You can't tell them apart until the paperwork catches up with you, months later.
Why it isn't taxed right away
You pay no tax on it the year it lands, because it isn't income.1
What happens instead is that the Canada Revenue Agency adjusts what it believes you paid for the investment. That number is your cost base, and the CRA measures your gain against it whenever you decide to sell.1
Say you put $10,000 into a fund. Over the year it pays you $500, and $200 of that turns out to be return of capital. You pay no tax on that $200 today. Your cost base drops instead, from $10,000 to $9,800.
Years later you sell it all for $11,000. It looks to you like a $1,000 gain. It's actually a $1,200 gain, because as far as the CRA is concerned, you paid $9,800.
None of that tax went away. You pay it later, when you sell.
Deferred, not forgiven
You will still pay this tax one day. Until then you keep the money, and you choose the year the bill lands.
That choice is worth real money to you. You pick when you sell, so you pick when you pay.
There's a second gain here. Interest income is taxed at your full rate, and capital gains are taxed on only half the amount.2 So money you would have paid full tax on this year can reach you later as a capital gain instead, at a lower rate.
There is a limit to it. If you keep receiving return of capital for long enough, your cost base falls to zero. After that, any more return of capital is taxed as a gain the moment it arrives.1 Your deferral has run out.
When you can ignore all of this
If your fund sits inside a registered account, none of it touches you.3 That means your tax-free savings account (TFSA), a registered retirement savings plan (RRSP), or a registered retirement income fund (RRIF). You have no cost base to track and no capital gain to report.
Return of capital only matters to you in a regular, non-registered account. If everything you own is registered, you can stop worrying about it right now.
The useful kind versus the worrying kind
Return of capital doesn't always mean the same thing, and the difference matters.
Sometimes it's ordinary accounting. A real estate investment trust, or REIT, is the classic case. A REIT can deduct depreciation on its buildings, which lowers its reported income even though the rent is still landing in its bank account. The cash it sends you is real. The income just doesn't show up on its books, so part of what you receive gets classified as return of capital. Nothing has gone wrong.
Sometimes it's a warning. A fund promises a headline yield it isn't earning, so it makes up the difference out of its own pot. You see a big number and buy in. Then the value of each unit slides downward, year after year, because the fund is shrinking itself to pay you.
In that second case you're paying a management fee to be handed your own money back.
If you own something like that, this is the uncomfortable part. You would still rather know now than find out years from here, with a sale already behind you.
You can tell the two apart yourself. Look at the unit price over five or ten years next to the distributions. If the price keeps sliding while your payout stays high, and the market itself hasn't fallen, ask the fund where the money is coming from. Most fund companies publish a breakdown of their distributions each spring, and it's worth ten minutes of your time.
What you actually have to do
Three things, and none of them are hard.
Keep your tax slips. For most funds and trusts, your return of capital shows up in box 42 of your T3.4
Track your own cost base, or at least keep the records that would let someone rebuild it for you. Your brokerage reports a cost base, but it's often incomplete, especially if you've ever moved an account between institutions. That number is your responsibility and not theirs. If it's wrong, you won't find out until you sell, which could be years from now.
Check what your funds actually pay you. Not the yield on the marketing page. Ask for the breakdown.
Nobody can hand you a history you never kept. If you've held a fund for years and moved it between institutions, your own records are the only place that number lives.
One note for retirees
Because return of capital isn't income, it doesn't raise your net income for the year. That can matter to you if you're near the point where Old Age Security starts getting clawed back, or where age-related tax credits begin to phase out.5 A dollar that doesn't count as income can't push you over.
That's a real advantage. It's also why certain products get marketed hard at retirees, so it helps to know why a salesperson likes the feature.
Before you judge a yield
A distribution isn't automatically income. A fund's yield tells you what it pays out. It doesn't tell you what it earned in order to pay you.
Your fund company publishes that split every spring. Once you have read it, you know which part of your yield the fund earned for you, and which part was your own money coming back.
Common questions
Do I have to report return of capital on my tax return?
Not for the year it reaches you. It isn't income, so you have nothing to enter. What it changes is your cost base, and that only shows up in the year you sell.
I've never tracked my cost base. Have I been filing wrong all these years?
No. Return of capital doesn't belong on a return for the years you receive it, so you haven't missed anything. The only return that could be affected is one for a year you actually sold. If that's happened to you, you can ask the CRA to adjust that year once you have the notice of assessment for it.
Where do I find the number?
Box 42 on your T3 slip. T3s tend to reach you later than your other slips, often not until the end of March, which is why people file before the number gets to them.
Does return of capital mean the fund is bad?
Not on its own. A real estate trust paying it because of depreciation is doing something ordinary. A fund paying it because it promised a yield it isn't earning is a different story. The way you tell is the unit price over several years alongside the payout.
Does any of this matter in my TFSA or RRSP?
No. You have no cost base to track and no capital gain to report in a registered account. If everything you own is registered, this isn't your problem.
My brokerage shows a book value. Is that my cost base?
It might be, and it might not. Brokerages often carry an incomplete figure, especially if you've ever transferred an account between institutions. Keep your own records so you can check theirs.
