Delaware Flip for a Canadian Startup: Tax in Both Countries

Is a Delaware flip taxable for Canadian founders?

Yes, in Canada, unless it is structured to defer the gain. A Delaware flip puts a new Delaware corporation on top of the Canadian startup so that US seed or Series A investors can buy shares of a US issuer. A straight swap of founder shares for Delaware parent shares is a sale at fair market value for a founder resident in Canada. The US does not tax that gain: under Article XIII(4) of the Canada–US tax treaty, it is taxable only where the seller lives.

Canada's usual tax-free share swaps do not help. A section 85 rollover needs a buyer that is a taxable Canadian corporation. Section 85.1 needs a Canadian corporation as buyer, and it is switched off if the founders control the buyer afterwards (85.1(2)(b)) or receive anything besides the buyer's shares (85.1(2)(d)). A Delaware corporation fails the first test.

There are three ways to flip:

1. Direct exchange. Founders swap their shares for Delaware shares and use the lifetime capital gains exemption, up to C$1.275 million of gain each, if the shares qualify.
2. Exchangeable shares. The Delaware parent sets up a Canadian exchange company. Founders roll their shares into it under section 85 for shares that can later be swapped for Delaware shares.
3. Continuance. The Canadian company itself moves its charter to Delaware. The founders keep their shares; the company pays Canadian emigration tax.

This is not a simple case: two countries, a corporation, an election with a strict deadline, and a one-time chance to use the exemption. Gather the cap table, share issue dates, the term sheet and a recent balance sheet before choosing a route.

Can the lifetime capital gains exemption cover the gain on our founder shares?

It can, if the shares are qualified small business corporation shares when the founder sells them and the founder was resident in Canada throughout the year. The section 110.6 tests, in short:

• At the sale, all or substantially all (90% or more in CRA's reading) of the company's assets by value are used in an active business carried on mainly in Canada.
• For the 24 months before, the company was a Canadian-controlled private corporation with more than 50% of its assets in that business.
• For those 24 months, nobody but the founder or a related person owned the shares.

The tests and their exceptions are in selling your business. Traps that hit startups:

• A company under 24 months old. Shares issued from treasury are deemed owned by an unrelated person just before they were issued (110.6(14)(f)), so they fail the 24-month test unless issued for other shares or for an active business's assets.
• Idle cash. Money from SAFEs, an earlier round or grants sitting in the bank can break the asset tests until it is spent or moved out.
• Residence. A founder resident only part of the year still qualifies if resident throughout the year before or after (CRA, line 25400). A founder leaving Canada the same year has more to plan: see moving across the border with a company.
• Minimum tax. The exemption removes regular tax, but federal minimum tax still counts 30% of the sheltered gain (s. 127.52, Form T691). Minimum tax paid can be credited against regular tax over the next 7 years (s. 120.2).
• Cash in the deal. If founders who control the Delaware parent take cash or a note for part of the price, section 84.1 can turn that part into a dividend. Any cash or note in the price needs checking under section 84.1 first.

The limit is indexed each year (s. 117.1); the 2026 figure is on CRA's indexation page. A flip in another year uses that year's limit.

How do exchangeable shares and a section 85 rollover defer the tax?

The exchange company is a taxable Canadian corporation, so section 85 works. Each founder transfers Canadian company shares to it for exchangeable shares, and the two jointly elect an amount on Form T2057. The elected amount, between the founder's cost and the value, becomes the founder's proceeds; any gain above it waits.

• Deadline. T2057 is due by the earliest income tax return filing deadline of either party for the transfer year (s. 85(6)). A late election is possible but carries a penalty (s. 85(7) and (8)).
• Quebec. A founder or company subject to Quebec tax also files Form TP-518-V, due by the later of the earliest relevant income tax return filing deadline and the last day of the second month after the later party's tax year-end.
• Later tax. The deferred gain is taxed when the founder swaps the exchangeable shares for Delaware shares or sells them. No rollover is available then, because the parent is not Canadian, and the exemption will no longer apply.

Exchangeable shares usually carry support and voting agreements so that they track the Delaware shares. Those terms are for counsel.

Should we crystallize the exemption before the flip closes?

If the shares qualify, the exemption has to be used at or before closing, because gain deferred past closing can never use it. "Crystallize" means triggering a gain now, while the shares still qualify, so that the exemption shelters it.

After the flip, neither the Canadian company nor the exchange company is a Canadian-controlled private corporation, because each is controlled by a non-resident (s. 125(7)). After a continuance the company is not even a Canadian corporation (s. 89(1)). The Canadian company also loses the tax breaks tied to that status, such as the enhanced refundable SR&ED credit and the small business rate: see losing CCPC status to foreign investors, which also covers a round that ends that status without a flip. Exchangeable shares and continued shares can never qualify.

• Exchangeable shares route. Elect on T2057 an amount equal to the founder's cost plus the remaining exemption room, so the gain the election triggers is fully sheltered.
• Continuance route. Only a disposition before the continuance can use it.
• Signing. A signed purchase agreement does not by itself end Canadian-controlled status for the share tests (110.6(14)(b)), but the company's own status, and its tax year, can end at signing: see losing CCPC status to foreign investors.

Counsel and the tax preparer fix the order of steps on closing day.

What if we continue the company into Delaware instead?

The company, not the founders, pays the tax. Delaware calls a continuance "domestication" (DGCL s. 388).

• Canadian residence ends. From the continuance, the Income Tax Act treats the company as incorporated only in Delaware (s. 250(5.1)). Under treaty Article IV(3)(a), as the US Treasury's Technical Explanation reads it, a company that gives up its Canadian charter is resident only in the US, even if run from Canada, so section 250(5) makes it non-resident for Canadian tax.
• Deemed sale. Its taxation year ends, and it is deemed to sell all its property at fair market value (s. 128.1(4)). Designs, patents and other intangibles are often where the value is.
• Emigration tax. It then owes, by that year's filing-due date, 25% of the value of its property minus paid-up capital (broadly, what shareholders paid the company for their shares) and debts (s. 219.1). Section 219.3 cuts the rate to the treaty rate on dividends to a company that owns all the shares, 5% under Article X(2)(a), unless one of the main reasons for the move was to cut Canadian tax.
• Afterwards. The engineers in Canada work for a Canadian branch of a US corporation, which files a T2 as a non-resident and may owe branch tax: see a US business expanding into Canada. For US tax the company is now a domestic corporation (26 USC 7701(a)(4)) filing Form 1120 on its worldwide income.

Founders who are not US persons owe no US tax on a continuance.

Which route costs the founders least?

It depends on value. Under the exemption limit, a direct exchange is simplest; above it, exchangeable shares defer the excess.

What flips the answer:

• A company under 24 months old, or one holding idle cash, may get no exemption at all.
• A Quebec founder adds TP-518-V.
• A founder who is a US citizen or green card holder has a US side too: a transfer of property for stock can be tax-free under 26 USC 351 when the transferors hold 80% control afterwards, but other US rules can apply and need review.
• Continuance costs more up front: the company pays tax on its value at once and leaves a branch to manage.

What do the Delaware parent, the Canadian company and the founders file after the flip?

The parent's Form 5471, NCTI and bank account reporting are in US parent of a foreign operating company. Missed reports: missed T1134 and missed Form 5472.

What records should we keep from the flip?

Keep everything that proves the value, the dates and the elections. A later CRA review, a T1134 or a buyer's due diligence will ask for them.

• Fair market value support for the shares at the flip
• The share register, issue dates and cap table before and after
• The exchange or continuance agreement and closing steps
• Filed T2057 and TP-518-V
• Paid-up capital of each class of shares
• Board minutes, and where the directors met, which supports where the parent is resident
• Exemption history: T657 and T936 for each founder

Example

All figures are illustrative, in Canadian dollars (C$), and assume the founders are resident in Canada, the shares meet every exemption test at the flip, and the C$1,275,000 exemption limit applies and has not been used before.

C$900,000 each: direct exchange

A Toronto chip design startup is at pre-seed. Two founders each own half of an Ontario corporation formed three years ago; each paid C$100 for their shares. A US seed fund's term sheet requires a Delaware parent, and each founder's shares are worth C$900,000.

• Each founder's gain is C$899,900, sheltered by the exemption, so no regular tax.
• Minimum tax counts 30% of it, about C$270,000; each founder runs T691.
• Each now holds Delaware shares with a Canadian cost of C$900,000 and has C$375,100 of exemption left.
• The Delaware parent files Form 1120, Form 5471 and Form 5472 (each founder owns 50%). Each founder files T1134.

C$3,000,000 each: direct exchange or exchangeable shares

The same startup flips a year later at seed, and each founder's shares are worth C$3,000,000.

• Direct exchange. Gain C$2,999,900, exemption C$1,275,000, C$1,724,900 left. Half, C$862,450, is taxable to each founder, with no cash from the deal to pay the tax.
• Exchangeable shares. Each founder and the exchange company elect C$1,275,100 on T2057. That gives a C$1,275,000 gain, all sheltered (minimum tax still checked), and exchangeable shares costing C$1,275,100. The other C$1,724,900 waits until the founder swaps them for Delaware shares or sells, and is then taxed without the exemption. Each founder checks whether a T1135 is needed.

C$4,000,000 of property: continuance

A Waterloo liquid cooling startup making cold plates and coolant distribution units considers continuing into Delaware. Its property is worth C$4,000,000, mostly designs and patents, with a tax cost of C$500,000. Paid-up capital is C$1,000,000 and debts are C$200,000.

• Deemed sale: C$3,500,000 of gain or income on its final Canadian-resident return, before any losses.
• Emigration tax, simplified: 5% × (4,000,000 − 1,000,000 − 200,000) = C$140,000, or C$700,000 at 25% if the treaty rate is denied.
• Its engineers then work in a Canadian branch of a US corporation.

Exchangeable shares trigger neither, because the operating company stays Canadian; the founders' deferred gain is still taxed later.

Different for you?

• The round changes control but there is no flip: losing CCPC status to foreign investors.
• No company exists yet: Delaware or Canadian corporation for a startup.
• The parent is run from Canada, earns interest, or pays dividends to founders: Canadian owner of a US corporation.
• The Canadian company charges the parent, or designs and patents move to it: pricing between your Canadian and US companies.
• Employees hold options that will be swapped for parent options: stock options for employees in Canada.
• Investors ask whether the Delaware stock is QSBS: small business stock exclusion for startups.
• Founders later sell the Delaware shares: Canadian founder selling US startup shares.
• T1134 and T1135 in general: foreign property and affiliate reporting.
• Planning a flip for a chip, cooling or GPU cloud startup with two countries' filings to line up: data center and infrastructure tax services.
