How to wind up a corporation in Canada, and the order to do it in

Summary

Winding up a corporation means selling what it owns, paying what it owes, and paying whatever is left to you as its shareholder. Finishing the job takes two separate endings, and the expensive mistakes come from treating them as one. Dissolution is a corporate-law step at the registry that created your corporation, meaning Corporations Canada if you incorporated federally and a provincial registry otherwise, and it ends the corporation’s legal existence. Closing the tax file is a separate job at the Canada Revenue Agency, or CRA: final tax returns, final slips reporting what the corporation paid people (e.g. a T4 for wages, a T5 for dividends, which are payments a corporation makes to its shareholders out of profit), and closing its CRA accounts. Those accounts are payroll, GST/HST (the sales tax it charges customers and hands to the CRA) and corporate income tax, not its bank account.

Neither ending does the other. For a solvent corporation with one owner, here’s the order we’d use, which isn’t the order the CRA’s own instructions give.

1. List what the corporation owns (cash, equipment, money customers still owe it), then look up its retained earnings. Retained earnings isn’t a separate pot of money. It’s the figure for how much of that value is profit already taxed in the corporation and not yet paid out to you.
2. Pay those retained earnings to yourself as dividends, over as many calendar years as it takes to keep your taxable income under $258,482, where the top federal rate of 33% starts in 2026.¹
3. Stop doing business, meaning no more sales and no more invoices, then close the payroll and GST/HST accounts on their own deadlines. Those fall within days of the day you stop, not six months after year-end.
4. Decide whether you need a clearance certificate, a CRA letter confirming the corporation’s taxes are paid or covered by money it has held back, before the last of the cash leaves.
5. Take that last cash out, file articles of dissolution at the registry, then file the final T2 (your corporation’s income tax return) for its final tax year. That year runs from the last normal year-end to the dissolution date printed on the certificate of dissolution the registry sends back.
6. Check whether the CRA still wants Form RC145 and a copy of the articles, and keep the corporate bank account open until any final refunds have landed, because a closed account leaves a cheque with nowhere to go.

The registry filing belongs at the end of that plan rather than the start, and “The clearance certificate” below explains why we put it there.

The registry step and the tax step

Dissolving a federal corporation is the quickest and cheapest part of a wind-up, which is partly why it gets done first. Articles of dissolution, the form asking the registry to close the corporation, cost nothing to file with Corporations Canada in 2026 and take about a day online.² If you incorporated provincially the form, the fee and the timing all differ, and some provincial registries refuse a dissolution until the province’s tax authority confirms in writing that provincial taxes are paid, so read your registry’s dissolution page early.

On the CRA’s side nothing happens by itself, and the corporation keeps owing a T2 every year until the registry actually dissolves it.³ Once it’s dissolved, check Form RC145, the request to close business number program accounts, to see whether the CRA still wants it with a copy of the articles. A federal dissolution often closes those accounts without the form. Where the CRA has no record of the dissolution, though, it keeps expecting returns from a corporation that no longer exists.⁴

Which years the money comes out in

A wind-up payment does two things at once. Everything paid out above the corporation’s paid-up capital counts as a dividend, and paid-up capital means what was paid to the corporation when its shares were first issued (e.g. $100 at incorporation). The rest is proceeds on your shares, usually producing no gain, though it can produce a capital loss worth claiming if your shares cost you more than that.⁵ The dividend is the expensive half, because a dividend is taxed more heavily than a capital gain of the same size.

How many calendar years the payments run over is the biggest lever you have, and it rarely feels like a tax decision. Paying yourself $300,000 of retained earnings in one calendar year puts part of it above $258,482, where the federal rate alone is 33% before your province adds its own. Spreading the same money over four years can keep each year’s dividend two brackets lower.¹ Each extra year you keep the corporation alive costs one more corporate return, one more T5 slip reporting the dividend, and one more registry annual return at $12 online federally in 2026.² On the flip side the money sits in the corporation while you wait, and dividend tax rates can move underneath a four-year plan.

The clearance certificate

A clearance certificate is a letter from the CRA confirming that a corporation’s taxes are paid or secured, meaning covered by money it has held back for them. You apply on Form TX19. The Income Tax Act says a legal representative, meaning whoever is winding up someone else’s property, has to obtain one before distributing that property.⁶ The CRA’s circular says the role may be assumed by a director, an officer or another person, with the facts of each case deciding. In a one-person corporation it’s you.⁷

The qualification that matters most sits in the same circular: you don’t need a clearance certificate before each distribution, as long as the corporation keeps enough property to pay any liability to the CRA. That’s the practical answer for most one-owner wind-ups. Pay yourself down to a reserve sized to cover the expected final tax bill, then file the final return and wait for the notice of assessment, which is the CRA’s written answer to a filed return. Apply on Form TX19 once it arrives, and release the reserve when the clearance certificate follows.⁷ A corporation registered for GST/HST needs a second clearance certificate for the sales tax, on Form GST352.⁸

Waiting costs months. The CRA’s published service standard for the 2026-27 fiscal year is 120 calendar days from the request, met in 90% of cases and excluding days spent under audit. It hit 88% in 2024-25, so treat 120 days as a target rather than a promise.⁹

What a reserve can’t fix is the last slice. The corporation’s final tax year ends on dissolution, and corporate law won’t dissolve a corporation until its property has been distributed and its debts paid.²¹⁰ Since the clearance certificate needs the assessed final return, it arrives after the last dollar has already gone. In our view a sole shareholder who is also the sole director, with the last few years filed, assessed and undisputed, can release that final reserve and dissolve without waiting for it. A representative who distributes without a clearance certificate is personally liable for the corporation’s unpaid amounts, capped at the value of what was handed out.⁶ The exposure is bounded, so you can size it before you take the money. Competent practitioners disagree with us here. Get the certificate if anyone else receives money (e.g. a spouse, a family trust, a minority shareholder), or if any return on any CRA account is unfiled, amended, or under review or dispute.

Deadlines that run from the day you stop

Several closing deadlines run from the date the business stops rather than from your corporation’s fiscal year-end, the annual date its tax year normally closes on. Payroll money withheld from pay and not yet sent to the CRA is due within seven calendar days of that date. T4 slips reporting employment income are due within thirty calendar days, instead of the usual last day of February following the year.³ A T5 slip reporting a wind-up dividend runs on that same thirty-day clock.¹¹

Closing the GST/HST account creates two reporting periods, and the return for the one ending the day before the account closes is due a month after that. Anything the corporation still owns is treated as sold at that point, so it remits GST/HST on the market value of ordinary business property and repays part of the sales tax it recovered on capital property, with no cash behind either amount.¹² Income tax does the same, so if you keep a corporate asset for yourself (a vehicle, a laptop), the corporation is taxed as though it sold it to you at market value.⁵

The final T2 is due six months after the final tax year ends, but the tax itself falls due two or three months after that year-end, depending on conditions a wind-up year can break.¹³

How often this changes

The mechanics here are unusually stable, and the statutory pieces (e.g. the rule that treats a wind-up payment as a dividend) have held for years. What moves is your own position, so we’d redo the calculation of how much to pay out this year and how much to leave for next each autumn while a wind-up runs. Personal brackets are indexed every January and the CRA resets its service standards annually, so confirm both in the month you file.

Closing thoughts

The part of a wind-up that costs real money almost never sits at the registry. The registry step is free and quick and feels like the main event, while the decisions that mattered got made months earlier, when you chose which years your money landed in. If the business is worth something to a buyer, work out the after-tax cash from a share sale before you work out the after-tax cash from a wind-up. A sale of qualifying shares can take a seven-figure capital gain out of tax under the lifetime capital gains exemption, which a wind-up can’t use at all. Otherwise go slowly, keep the corporation alive until every CRA account shows a zero balance, and leave the registry until last.

How we handle it

We map a wind-up as a calendar before anything gets filed: which years the dividends land in, the payroll and GST/HST closing dates, the final T2, and the registry filing at the end. The T5 slips, the corporate returns and your personal return are prepared together by the same person, so the slip, the T2 and your T1 agree. Where a clearance certificate is the right call we prepare the TX19 with the schedule the CRA asks for.
