Many incorporated business owners look at their corporation's retained earnings — the accumulated profit sitting on the balance sheet — and think of it as money already spoken for. In tax terms, though, retained earnings occupy an in-between status: they've already been taxed once, inside the corporation, but a second layer of tax is usually still waiting whenever that money is eventually paid out to a shareholder.
Understanding how retained earnings are taxed while they sit in the corporation, and what happens the moment you draw them out, helps you plan compensation and dividend decisions instead of being surprised by them.
What "Retained Earnings" Actually Means
Retained earnings is an accounting concept: it's the corporation's cumulative after-tax profit that hasn't been distributed to shareholders as dividends or otherwise paid out. It builds up on the balance sheet year over year, increased by net income and reduced by any dividends declared.
Tax Happens First, at the Corporate Level
Before profit ever becomes "retained earnings," it's taxed as corporate income in the year it's earned. An Ontario corporation eligible for the small business rate currently pays a combined federal and Ontario rate on the first $500,000 of active business income — 9% federally, and 2.2% provincially as of July 1, 2026, down from 3.2% — while income above that threshold, or income earned by a corporation that doesn't qualify for the small business rate, is taxed at the general combined rate of 15% federally and 11.5% in Ontario. Whichever rate applies, that tax is paid whether or not the corporation ever distributes the profit to its shareholders.
Why Retained Earnings Isn't the Same as Cash
A common misconception is that retained earnings on the books means there's a matching pile of cash available to pay out. In reality, retained earnings can be tied up in inventory, equipment, receivables, or simply reinvested in the business — the accounting figure reflects accumulated after-tax profit, not a bank balance. Before promising a dividend based on retained earnings, confirm the corporation actually has the liquidity to pay it.
Paying It Out: The Shift to Personal Tax
When retained earnings are eventually paid out as a dividend, the shareholder is taxed personally on that amount. Canada's tax system is built around the idea of "integration": since the corporation already paid tax on that income once, the personal dividend tax rules, through a dividend tax credit mechanism, are meant to roughly account for the corporate tax already paid, so the same dollar of profit isn't taxed at the full combined corporate-and-personal rate as if it had never passed through a corporation. The mechanics of the credit are technical and depend on the specific dividend and personal circumstances involved — this is squarely a job for your accountant at planning time, not a do-it-yourself calculation.
The Capital Dividend Account: One Tax-Free Exception
There's one meaningful exception to the "eventually taxed on the way out" rule. Because only half of a capital gain is included in a corporation's taxable income under the current inclusion rate, the other, untaxed half can generally be paid out to shareholders tax-free through the corporation's Capital Dividend Account — a notional tracking account, not a real bank account, that accumulates the non-taxable portion of capital gains, among other items, the corporation has realized. Getting a capital dividend election right is technical, and getting it wrong can trigger unexpected tax consequences, so this is not a step to take without professional advice.
Retained Earnings and Business Value
Retained earnings also matter beyond tax: they're often a factor in how a business is valued, whether by a potential buyer, a lender, or in a shareholder dispute. A corporation with large retained earnings sitting idle, rather than reinvested or distributed, can also raise the question of whether that cash is being used efficiently — a business strategy conversation, but one that often ends up in the same room as the tax planning discussion.
Frequently asked questions
Do retained earnings get taxed again just for existing?
No. Retained earnings themselves aren't subject to an ongoing separate tax simply for staying in the corporation. The corporate tax was already paid on the income when it was earned; the second layer only applies once the money is actually paid out to a shareholder.
Can I avoid personal tax by leaving profit in the corporation indefinitely?
You can defer the second layer of tax by not paying dividends, but "indefinitely" has practical limits — eventually the money is either paid out, used in a wind-up (which has its own tax consequences), or passed on through a sale of the shares.
Is salary better than dividends for pulling out retained earnings?
It depends on the specific numbers, the owner's personal situation, and factors like CPP contributions and RRSP room. There's no universal answer, and it's exactly the kind of calculation your accountant should run before you decide.
Does paying a large dividend affect the corporation's ability to get financing?
It can. Lenders often look at retained earnings and cash reserves as an indicator of financial strength, so a large distribution shortly before seeking financing can affect how a lender views the corporation.
