Should I hold my startup shares personally or through a holding company?
Holding the shares personally keeps two personal tax breaks a holding company can never claim: Canada's lifetime capital gains exemption, worth up to C$1.275 million of gain on qualifying Canadian shares, and US QSBS on Delaware shares if you later become a US resident. A holding company (holdco) instead keeps sale proceeds inside a corporation, where they can be invested before any personal tax on a payout.
| Question | Shares held personally | Shares held by your holdco |
|---|---|---|
| Lifetime capital gains exemption | Possible on qualifying shares of a Canadian-controlled private corporation; never on Delaware shares | The holdco cannot claim it; only your holdco shares might qualify |
| US QSBS on Delaware shares | Possible if you are a US resident or citizen when you sell and the tests are met | Not available to the holdco, and lost for good on those shares |
| Gain on Delaware shares while you live in Canada | Usually taxed only in Canada | Usually taxed only in Canada |
| Tax at sale | 50% of the gain in your income | 50% of the gain taxed in the holdco at investment-income rates |
| Cash after the sale | Yours, after personal tax | Stays in the holdco until paid out; the untaxed part can come out as a tax-free capital dividend |
| Dividends from a Canadian startup | Taxed to you as dividends | Usually deductible to the holdco; refundable Part IV tax may apply |
| Annual filings | Your return; Form T1134 or T1135 if the startup is foreign | A T2 every year plus T1134 or T1135, and your own return |
A case is not simple if it involves a Delaware company, a possible move to the US, a stake large enough to control the startup, shares that already have value, or a Quebec holdco. Choosing after shares are issued usually means a valuation and a rollover. Gather the cap table, the startup's country of incorporation, the shareholder agreement and vesting terms, and any plans to move.
Does a holding company give up the lifetime capital gains exemption?
Yes. The deduction in section 110.6(2.1) is only for "an individual (other than a trust)" resident in Canada throughout the year. A corporation that sells startup shares cannot claim it.
What you can still sell are your holdco shares, which may be qualified small business corporation shares if the holdco's assets are shares of connected small business corporations and stacked asset tests are met: more than 50% of value in qualifying assets through the 24 months before the sale, and 90% at the sale for the small business corporation test. That only helps if a buyer agrees to buy the holdco, not the startup.
The exemption also needs a Canadian-controlled private corporation, which must be a Canadian corporation (section 125(7)). Shares of a Delaware startup never qualify, held personally or through a holdco. For the tests after a venture round, see the exemption on a startup exit.
Does a holding company give up US QSBS if I ever become a US resident?
Yes. Section 1202(a) excludes gain only for "a taxpayer other than a corporation", so a Canadian holdco cannot use it. The stock must also be acquired by the taxpayer at original issue, and only gifts, death and certain partnership distributions carry QSBS status to a new owner (section 1202(h)). A holdco later handing the shares to you is not on that list.
QSBS matters mainly if you might become a US resident or citizen before an exit. While you live in Canada, a gain on Delaware shares is usually taxable only in Canada under Article XIII(4) of the treaty, unless the company's value comes mainly from US real property. Leaving Canada is usually a deemed sale at fair market value of the shares you own, startup or holdco shares alike (section 128.1(4)). A US resident who owns a Canadian holdco also takes on US foreign-corporation rules; see moving to the US as a founder. For the holder tests, see QSBS for founders.
What does the holding company file for shares in a Delaware startup?
A holdco files a T2 every year, and a Form T1134 for each year the Delaware startup is its foreign affiliate. If the holdco's cost of the shares stays under C$100,000 and the startup is dormant (gross receipts, including money raised, under C$100,000 and assets never above C$1,000,000), the T1134 needs only basic information about it, not a full supplement. A non-resident corporation is a foreign affiliate when the holdco's equity percentage in it is at least 1% and the holdco plus related persons own at least 10%; the test applies at any time in the year (CRA T1134 questions and answers). T1134 is due 10 months after the holdco's year end.
If the startup is not a foreign affiliate, its shares are specified foreign property, and Form T1135 is required when the holdco's total cost of such property passes C$100,000. Shares of a foreign affiliate are excluded from that count (section 233.3). You file the same forms personally if you hold the shares yourself, so the holdco moves the filing rather than removing it.
On the US side, the Delaware startup files Form 5472 for reportable transactions with a foreign owner of 25% or more, counted directly or indirectly (IRS instructions). The startup may ask the holdco for a Form W-8BEN-E. For T1134 details and penalties, see foreign property and affiliate reporting.
How is a sale taxed inside the holding company, and how does the money reach me?
The holdco includes 50% of the gain in income as investment income. A Canadian-controlled private corporation pays an additional refundable tax of 10 2/3% on that income (section 123.3), and part of the corporate tax is refunded when the holdco later pays you taxable dividends (section 129).
The untaxed part of the gain is added to the holdco's capital dividend account (section 89(1)). The holdco can pay that amount to you as a capital dividend by filing an election (Form T2054) no later than the day the dividend becomes payable or is first paid, whichever is earlier, and you include none of it in income (section 83(2)). An election above the account balance triggers Part III tax of 60% on the excess, and each shareholder who received the dividend can be made to pay a share of it (section 185(4)).
The rest reaches you as taxable dividends when you choose, which is the deferral a holdco offers. For the full tax on a sale of US shares, including a section 93 election to treat part of a foreign affiliate's gain as a dividend, see selling US startup shares as a Canadian founder.
For a Canadian startup: can the holding company receive dividends tax-free?
Usually, yes, at first. A corporation deducts taxable dividends from a taxable Canadian corporation in computing taxable income (section 112(1)). A private holdco may still owe refundable Part IV tax (section 186):
| Holdco's stake in the startup | Part IV tax on the dividend |
|---|---|
| Connected: holdco controls the startup, or owns more than 10% of the voting shares and of the share value | Only the holdco's share of the dividend refund the startup received |
| Not connected | 38 1/3% of the dividend, refundable when the holdco pays dividends |
A dividend paid with a purpose of significantly reducing a capital gain, and that exceeds the income earned on the shares (safe income), can be recharacterized as a capital gain under section 55(2). This matters when cash is moved to the holdco before a sale. For safe income and investment income inside a holdco, see holding and investment corporations.
Does a holding company change the startup's small business and SR&ED limits?
Control decides it, not the holdco itself. Two corporations are associated if one controls the other, or both are controlled by the same person or group (section 256(1)). A founder who controls the startup is associated with their own holdco whether the startup shares sit personally or in the holdco.
Associated Canadian-controlled private corporations share one C$500,000 business limit (section 125(3)) and one SR&ED expenditure limit of up to C$6 million (section 127(10.3)). The holdco's investment income also counts toward the passive-income reduction that starts at C$50,000 of adjusted aggregate investment income (section 125(5.1)). A founder with a minority stake whose holdco does not control the startup is usually not associated, but related-person and group-control rules make this fact-dependent. These limits apply only to Canadian corporations; see SR&ED and small business limits after a large round.
Can vesting still apply when a holding company owns the shares?
Vesting and repurchase terms can be written for a holdco shareholder, but how each country taxes those shares is not settled. US section 83(a) reaches property transferred "to any person" in connection with services, so a holdco does not by itself take the shares outside the US rules. The regulations tax the person who performed the services and let that person make the 83(b) election (Treas. Reg. 1.83-2(a)), but no official guidance addresses shares issued to the founder's own corporation. Canada's employee-share rules in section 7 turn on whether the founder is an employee and how the shares are issued.
Treat holdco-held vesting shares as a question to resolve before issue, with the startup's counsel. For founders who hold vesting shares personally, see vesting Delaware founder shares.
Can I move the shares into a holding company later, and what does waiting cost?
Yes. You and the holdco can file a joint election under section 85(1) to transfer the shares for holdco shares at an agreed amount, deferring the gain. The election is due by the earliest income tax return filing deadline of either party for the transfer year. The general mechanics are in moving a business into a corporation.
Waiting costs more once the shares have value:
- Valuation: an agreed amount above fair market value is deemed to equal that value (section 85(1)(c)), and the CRA can test the value you used, so you need a supportable valuation at the transfer date.
- Exemption: after the transfer you own holdco shares, and only those can carry the exemption if they qualify. Holdco shares issued in exchange for other shares avoid the rule in section 110.6(14)(f) that starts a new 24-month ownership test for newly issued shares.
- Cash or notes: taking cash or a note worth more than the Canadian startup shares' paid-up capital or adjusted cost, whichever is greater, can be a deemed dividend under section 84.1.
- QSBS: Delaware shares moved to a holdco lose QSBS permanently.
- Consent: the shareholder agreement may require investor or board approval.
Moving shares back out later is a disposition by the holdco; a transfer to you for less than fair market value is deemed made at that value (section 69(1)(b)).
What should I settle before the shares are issued?
Settle who will own the shares before they are issued, when they are worth the least. Then:
- Confirm whether the startup is, or may become, a Delaware or Canadian corporation; see Delaware or Canadian corporation and moving under a Delaware parent.
- Decide whether a US move before an exit is possible; that favours holding Delaware shares personally.
- If you use a holdco, incorporate it first so it subscribes for the shares directly.
- Check that the shareholder agreement and vesting terms allow a corporate holder.
- Map control and association with your co-founders.
A family trust is a separate structure drafted by a lawyer. Quebec applies its own corporate tax and capital gains deduction rules, including a deduction limit of C$637,500 of taxable capital gains.
Example
These examples are illustrative; figures are in Canadian dollars.
A C$5 million gain on an Ontario startup
A founder sells shares of an Ontario startup for a gain of C$5 million. Held personally, the exemption can shelter up to C$1.275 million of the gain if the shares are qualified small business corporation shares; the remaining C$3.725 million is a capital gain, half of it (C$1.8625 million) taxable. Held by a holdco, no exemption applies: C$2.5 million is taxable in the holdco, and the other C$2.5 million (the untaxed half) enters the capital dividend account and can be paid to the founder tax-free.
30% of a Delaware startup through a Quebec holdco
A Quebec holdco owns 30% of a Delaware startup. The startup is the holdco's foreign affiliate, so the holdco files a T1134 every year, and the startup files Form 5472 for any reportable transactions with its foreign owner. The founder moves to San Francisco two years before the exit. Having lived in Canada for years, the founder is deemed to sell the holdco shares at fair market value on leaving. QSBS is not available on the startup shares, because a corporation holds them, and the founder now owns a Canadian corporation as a US resident.
Shares rolled into a holdco after a Series A
A founder's shares in a Canadian startup cost C$100 and are worth C$4 million after a Series A. The founder transfers them to a new holdco for holdco shares and elects C$100 under section 85, so no gain is taxed now. The holdco cannot claim the exemption when the startup is sold; only the founder's holdco shares can carry it, and only if they qualify.
