First, confirm the corporation is allowed to pay it
Before any tax question, a dividend has to clear corporate law: under the Ontario Business Corporations Act, directors cannot declare a dividend if there are reasonable grounds to believe the corporation could not pay its liabilities as they come due afterward, or that the realizable value of its assets would fall below its liabilities plus stated capital. Directors who approve a dividend that fails this test can be personally liable to restore the money. For a large, lumpy distribution this is not a formality; it is the first real check.
Retained earnings on the balance sheet are not the same thing as distributable cash. A corporation can show healthy retained earnings while its cash is tied up in receivables, inventory or a building, and stripping the bank account to fund a dividend then borrowing back operating cash is a self-inflicted wound. Look at the next twelve months of obligations, tax instalments and planned capital spending before setting the amount.
Two outside parties get a vote as well. Credit agreements routinely restrict distributions or impose covenant ratios a large dividend would break, so the loan agreement gets read before the resolution is drafted. And if the corporation owes CRA anything material, paying shareholders ahead of the tax debt creates personal exposure for the recipients through the transfer rules. Neither problem has a tax fix after the fact.
Decide what kind of dividend it is before you decide the amount
A large dividend should be layered, not uniform, because a private corporation can usually pay three different kinds and they are taxed completely differently. The order of review runs from the cheapest to the most expensive.
Start with the capital dividend account. The CDA collects the tax-free halves of capital gains, life insurance proceeds and certain other amounts, and it can be paid out entirely tax-free, but only by election filed on or before the day the dividend becomes payable. The balance is a running computation, reduced by capital losses along the way, so it gets recalculated as of the payment date rather than pulled from last year's file. Electing more than the true balance attracts a penalty tax of 60% of the excess, so precision here is not optional.
Large CDA balances usually arrive in lumps: the sale of a business or property, or life insurance proceeds after a shareholder's death, which is exactly when large dividends get paid, and why this account is checked first every time. The balance is fragile in the wrong direction too, since a capital loss realized before the election shrinks it. The sequence of portfolio trades and the election date get coordinated rather than left to chance.
Then eligible dividends, which can be paid up to the GRIP balance, the pool built by income taxed at the general corporate rate. They must be designated as eligible in writing to the shareholders at the time of payment, and they are taxed at a meaningfully lower personal rate than ordinary dividends; over-designating beyond GRIP attracts its own 20% penalty tax on the excess. Whatever remains is a non-eligible dividend, the default, taxed highest in the shareholder's hands.
| Dividend type | Account it draws on | Corporate side | Shareholder side |
|---|---|---|---|
| Capital dividend | Capital dividend account (CDA) | Election filed on or before the payable date; 60% penalty tax on any excess | Completely tax-free |
| Eligible dividend | GRIP (general-rate income) | Written designation at time of payment; refund only from the eligible RDTOH pool | Lower rate through the enhanced dividend tax credit |
| Non-eligible dividend | Remaining after-tax income | Refund from the non-eligible RDTOH pool first | Highest personal rate of the three |
Check the refundable tax pools: RDTOH turns dividends into refunds
If the corporation has been earning investment income, part of the tax it already paid is waiting to come back, and the dividend is what releases it. Refundable dividend tax on hand accumulates from the refundable portion of tax on investment income and from Part IV tax on portfolio dividends, and the corporation recovers 38.33 cents for every dollar of taxable dividend it pays, capped at the pool balance. On a large dividend this refund is real money, and it means the after-tax cost of the distribution is lower than the personal tax bill makes it look.
Since 2019 the pool is split in two, and the split changes which dividend to pay. Eligible dividends can only trigger refunds from the eligible pool (ERDTOH); non-eligible dividends draw from the non-eligible pool first, then the eligible one. The classic error is paying a large eligible dividend for the lower personal rate while a non-eligible RDTOH balance sits stranded, unrefunded. The right answer is usually a computed blend: enough non-eligible dividend to flush NERDTOH, eligible dividends against GRIP for the rest.
Sizing matters too. A dividend larger than the RDTOH balances support recovers everything and then runs refund-free, while a dividend split across two corporate year-ends can release two years of refund capacity. This is arithmetic on the corporation's own schedules, and it should be done to the dollar before the amount goes in the resolution.
The pools cut both ways, because tax paid on portfolio dividends the corporation received sits in RDTOH too, waiting on the same trigger. The general point is that refundable tax is a timing account, and a large distribution is the moment the timing pays off. A refund left unclaimed because nobody pulled the schedule is the most common miss in dividends paid without a review.
Look at who is receiving it and what it does to their return
A large dividend to anyone other than the active owner has to clear the tax on split income first, because TOSI taxes caught dividends at the top personal rate with no brackets to climb. A spouse or adult child receiving part of the distribution needs a real exclusion: regular engagement in the business averaging roughly 20 hours a week now or in five earlier years, qualifying excluded shares at 25 or older, or the age-65 splitting rule that lets a retired owner's spouse stand in the owner's shoes. If no exclusion fits, routing part of the dividend to family saves nothing and adds risk.
If the shareholder is a holding company rather than a person, the analysis changes shape. Intercorporate dividends between connected corporations generally move tax-free, which is much of why holdcos exist, but a dividend that triggers a refund in the payer generates Part IV tax in the corporate recipient, roughly mirroring the refund. Nothing is lost overall; the refundable tax moves up a level, to come back when the holdco pays its own dividends. It still has to be computed, because the holdco's instalments and its own RDTOH position move with it.
For the owner personally, remember that nothing is withheld on a dividend. The personal tax lands at filing, and a big dividend year drags quarterly instalments behind it the following year, so a fixed share of the cash should be set aside on day one. A very large dividend can also interact with the alternative minimum tax, which runs a parallel calculation that large, lightly-taxed receipts can trigger; it gets modelled before the amount is final, not discovered in April.
Timing is the last owner-level lever. Splitting the distribution across December and January spreads it over two personal tax years and two bracket runs, while paying inside the corporation's current fiscal year may matter for the RDTOH refund. Those two calendars, the corporation's and yours, do not always agree, and the resolution date should be chosen deliberately against both. A week of planning either side of December 31 is often the difference between one bracket and two.
The facts to pin down, the paperwork, and who should check it
Five numbers, current as of the payment date rather than last year's filing, decide the shape of a large dividend:
- Distributable position: the solvency test, real cash, covenants and any CRA balance.
- The CDA balance, recomputed to the payment date, for the tax-free layer.
- GRIP, for how much can be designated eligible.
- Both RDTOH balances, for the refund and the eligible/non-eligible blend.
- The shareholder mix, for TOSI, brackets, instalments and timing.
Then the paperwork, which is short but unforgiving: a directors' resolution declaring the dividend and its date, the capital dividend election filed on or before the payable date, the eligible designation given to shareholders at payment, and T5 slips filed by the end of February for the calendar year. The elections are the sharp edges; the resolution and slips are recoverable, the elections mostly are not.
Do the review before declaration, because the failure modes are asymmetric. A dividend that should have been split across two years, or blended differently across the pools, is merely expensive. A missed capital dividend election, an over-election, or a dividend that fails the solvency test lands in penalty territory, and the deadline for the CDA election is the payable date itself. The order of operations is the protection.
The reason this review works better as a habit than a scramble is that every number in it is maintained, not invented. Under an Ongoing Financial Partnership the CDA, GRIP and RDTOH schedules are kept current through the year, so a distribution decision is a short calculation instead of an archaeology project. If dividends this size are becoming regular, that is really a compensation-policy question, the territory of corporate tax planning for owner-managed businesses, and a corporate tax planning CPA in Ontario should be setting the annual pattern rather than blessing one-off payouts.
