Reverse Vesting (Founder Shares)

With ordinary vesting, a person earns the right to acquire shares over time. Reverse vesting runs the other way. The founder subscribes for all of their shares at the outset, usually for a nominal price at incorporation, and signs an agreement giving the corporation, or the other shareholders, the right to buy back the unvested portion if the founder stops working for the business before the schedule ends. Each month or quarter of service releases more shares from that repurchase right until none remain.

The structure fits Ontario corporate law. Section 23 of the Business Corporations Act prohibits issuing a share until it is fully paid in money, property or past service, so work a founder has not yet done cannot pay for shares. Issuing everything up front for cash, then buying back what has not been earned, produces the economics of earning shares over time without issuing shares for future services. It is the usual way sweat equity is made to work in a corporation.

The terms normally sit in a founders' shareholder agreement or a stand-alone share repurchase agreement. Our article on why founder agreements matter covers why founders and investors want vesting.

A typical clause covers:

• Trigger. The founder stops providing services as an employee, officer, director or consultant, for any reason or for listed reasons.
• Unvested shares. The holder of the right may buy them within a set period, often 60 to 90 days, at the lower of the founder's original subscription price and fair market value.
• Vested shares. The founder keeps them. Some agreements add a right to buy vested shares at fair market value, or at a discount for a bad leaver, which is heavily negotiated.
• Security for the right. Share certificates are often held in escrow with a signed share transfer form or a power of attorney, so the repurchase can close without the departed founder's cooperation.

If the corporation itself buys, solvency limits apply. Section 30 of the OBCA bars a payment to purchase its own shares if there are reasonable grounds to believe the corporation could not pay its liabilities as they become due, or that the realizable value of its assets would fall below its liabilities plus its stated capital. Where the departing founder is a current or former director, officer or employee and the right is in a non-assignable agreement, section 31 substitutes a lighter asset test, but the corporation must still be able to pay its debts. A startup that has spent its investors' money can fail the section 30 stated capital test even for a nominal payment, so the directors' resolution should record which test applies and why it is met. Many agreements let the other founders buy instead, which is a share transfer rather than a corporate purchase.

On a corporate purchase, section 84(3) of the Income Tax Act deems any amount paid above the shares' paid-up capital to be a dividend. A repurchase at the original subscription price, which usually equals paid-up capital, generally produces neither a deemed dividend nor a capital gain.

US founders holding restricted stock can file a section 83(b) election under the US Internal Revenue Code so that they are taxed when the shares are issued rather than as they vest. Canada has no equivalent election, and none is needed.

Under section 7 of the Income Tax Act, an employment benefit from acquiring shares is measured by their value at the time the employee acquired them, less the amount paid. A reverse-vested founder acquires the shares when they are issued and becomes their registered owner, usually with full voting and dividend rights. Escrowing the certificates does not change that, and section 7(2) separately deems shares held by a trustee for an employee, even conditionally or contingently, to be acquired when the trustee began to hold them. Because the founder already owns the shares, vesting is generally not a taxable event.

A founder who pays fair market value at issuance, which at incorporation is a nominal amount, therefore generally has no taxable benefit then or later as shares vest. The risk case is a co-founder who joins after the company has value and receives shares at the original founders' price. That can create an employment benefit measured at issuance, deferred until sale only if the CCPC and arm's length conditions in section 7(1.1) are met, so late founders' shares should be priced with tax advice.

Reverse vesting also starts the clock for the lifetime capital gains exemption, which for 2026 can shelter up to $1,275,000 of gains on qualified small business corporation shares. One test is that, for the 24 months before a sale, no one other than the seller or a related person owned the shares. Section 110.6(14)(f) deems newly issued shares to have been owned by an unrelated person immediately before their issue, unless they were issued in exchange for other shares, on a transfer of all or substantially all the assets used in an active business, or as a stock dividend. In practice, a share issued from treasury for cash must be held for 24 months by the founder or a related person before it can qualify.

A founder on reverse vesting who sells three years after incorporation can meet the holding test for every share, including shares that were still unvested a year earlier. Options exercised shortly before a sale cannot. The other QSBC tests, including CCPC status and the active-asset tests, must still be met. Where a holding company or family trust will hold the founder's shares, the agreement should tie vesting to the individual founder's services while the repurchase right attaches to the shares the entity holds, and the tax effect of that structure needs separate advice.

The schedule itself is rarely contested. These points usually are:

• Credit for time served. Founders who have already worked a year or two often negotiate a portion that is vested on signing.
• Re-vesting at a financing. Seed and Series A investors may ask founders to put fully vested shares back on a schedule; founders push for credit and a shorter remaining term.
• Leaver definitions. Death, disability and termination without cause are often treated as good leaving, with more shares kept or a better price for vested shares.
• Who may buy, and how long the right lasts. The corporation first, then the other founders pro rata, within a fixed window so the right does not hang over a departed founder.
• Acceleration. Single and double trigger acceleration on a sale work as they do on an option vesting schedule. Double trigger is common; partial single trigger is a frequent compromise.

Lamba Law's founder agreements and vesting practice drafts these terms, and the free vesting calculator shows how a given schedule and cliff play out month by month.

Leila Farahani and Marcus Bennett incorporate Northlark Robotics Inc. in Markham in January 2025. Each subscribes for 4,000,000 common shares at $0.0001 per share, paying $400. Their shareholder agreement puts both founders on four-year reverse vesting with a one-year cliff, then monthly vesting. The corporation may repurchase unvested shares at the original price within 90 days after a founder leaves; if it does not, the other founder may buy them on the same terms.

Marcus leaves in September 2026, 20 months in. He has vested 1,000,000 shares at the cliff and about 666,667 more over the following eight months, for 1,666,667 in total. The board passes a resolution confirming the solvency tests and repurchases his 2,333,333 unvested shares for $233.33. The shares are cancelled, and the securities register and cap table are updated. Leila now holds 4,000,000 of 5,666,667 issued shares, about 70.6%; Marcus keeps about 29.4%.

Because the price equals the paid-up capital of the repurchased shares, there is no deemed dividend and Marcus has no gain or loss. All of Leila's shares were issued in January 2025, so they can meet the 24-month holding test from January 2027, even though her last shares do not vest until January 2029. The other QSBC tests will be measured if and when she sells.
