How to Set Up an Employee Stock Option Plan for Startups

If you are building an early-stage startup, you probably cannot pay everyone big-company cash.

That is exactly why founders create an employee stock option plan.

A good employee stock option plan helps you attract talent, retain key hires, and align your team with the upside of the business. It also makes your company look more investable. Many investors expect to see a real startup option pool in place before a priced round, and around 10% is a common rule of thumb, although it is not a hard legal requirement. Carta notes that about 10% is a common pool target, and that investors often negotiate the option pool as a core financing term.

This guide explains how to set up an employee stock option plan, what approvals you usually need, how vesting works, and what founders should watch for before investors start legal due diligence.

What is an employee stock option plan?

An employee stock option plan, sometimes called a startup option pool or equity incentive plan, gives employees the right to buy company shares later at a pre-set price, usually after they vest over time. CRA describes a stock option plan as a plan where the employer grants the employee the option to purchase securities at a predetermined price within a specified period. CRA also describes the vesting period as the period during which the employee has the rights but cannot yet exercise, sell, or transfer them.

This matters because stock options are not the same thing as shares on day one. A grant gives a recipient the right to buy shares later. They only become an actual shareholder after exercise, subject to the plan terms and the company's documents. Carta's equity guide makes the same point clearly: a stock option grant does not automatically issue equity, and recipients must exercise to actually own shares.

Why investors care about your startup option pool

Investors care about your employee stock option plan for two reasons.

First, they want to know your company can still hire. If you have no room to incentivize future engineers, operators, and senior hires, your post-financing growth plan looks weak. Carta's option pool guidance says the pool should be large enough to support hiring through the next financing event.

Second, investors care about dilution. Carta explains that when a target option pool is baked into the pre-money cap table, the increase usually dilutes the existing holders, not the new investor. That is why investors often ask founders to create or expand the employee option pool before the round closes.

So yes, when founders say, "investors want 10% reserved for ESOP before investing," that is directionally right as a market practice. It is just not a universal legal rule. The right number depends on your hiring plan, your fundraising stage, and how aggressively you expect to recruit before the next round.

How big should your employee option pool be?

For most early-stage startups, the real question is not "Should I have an option pool?" It is "How large should the option pool be?"

A common benchmark is about 10% of the company, but that number should come from a hiring model, not founder folklore. Carta's current guidance says 10% is a common rule of thumb, but it also says the right size varies depending on comparable companies, stage, and expected hires.

A practical founder approach is:

• Map the next 12 to 24 months of hiring
• Estimate which roles need meaningful equity
• Model the grants needed for those roles
• Reserve enough shares to get to the next financing, but not so much that you create unnecessary dilution

The biggest mistake here is creating a larger pool than you actually need just because an investor tossed out a number. Carta warns that an oversized pool dilutes founders and other existing holders.

What approvals do you need for a stock option plan?

Usually, the board is the starting point.

Under the CBCA, directors manage or supervise the management of the business and affairs of the corporation. The CBCA also says a corporation may issue options or rights to acquire securities, and if the articles limit authorized shares, the corporation must reserve enough authorized shares to satisfy those options and rights.

That is the core legal reason founders typically need board approval for the employee stock option plan and for the actual grants made under it. Cooley also notes, in the US startup context, that an effective option grant generally requires formal board approval rather than just a promise in an offer letter.

That said, your board resolution may not be the only approval step. Depending on your articles, by-laws, unanimous shareholder agreement, investor documents, exchange rules, or cross-border tax goals, you may also need shareholder approval or additional procedural steps. Under the CBCA, a unanimous shareholder agreement can restrict the directors' powers, which means you cannot look at board approval in isolation.

How to set up an employee stock option plan step by step

1. Decide what your plan is for

Start with strategy before paperwork.

Are you building a plan only for employees? Or do you also want to grant equity to advisors, executives, directors, and consultants?

Carta's equity compensation guide notes that equity-based compensation can be used not just for employees, but also for other service providers such as advisors.

Your eligibility rules should be written clearly in the plan.

2. Confirm your share structure can support the plan

Before promising anyone options, make sure your corporation can actually issue them.

For a CBCA corporation, the company may issue options or rights to acquire securities, and if the articles limit authorized shares, it must reserve enough shares to cover exercises.

In practice, that means you should review:

• Articles of incorporation
• Share classes
• Authorized share limits, if any
• Any unanimous shareholder agreement
• Your current cap table
• Any existing investor rights that affect equity issuance

3. Choose the pool size

This is where you set the size of the employee option pool.

For many startups, that means a 10% option pool is the starting conversation. But the better answer is to model likely grants for the next 12 to 24 months. If you are about to raise, remember that the timing of the option pool can change who takes the dilution hit.

4. Draft the actual plan documents

At minimum, founders usually need:

• A stock option plan
• Board resolutions approving the plan
• A form of option grant agreement
• Updated cap table records
• Minute book records showing the approvals and grants

Carta's equity compensation guide notes that grant documents should contain key terms such as the grant date, the number of options, the fair market value or exercise price, and the vesting schedule.

5. Set the exercise price and vesting schedule

The exercise price is the price the option holder pays to buy the shares later.

The vesting schedule for stock options is the timeline for when the options become exercisable. Carta's guidance says the most common vesting schedule is four years with a one-year cliff, which means the recipient earns nothing if they leave before the first year, then vests into the remaining grant over time.

That typical four-year vesting schedule works well for most startup employee equity plans because it rewards staying power and avoids giving away long-term upside to people who leave early.

6. Approve the plan and approve each grant properly

Do not treat a casual promise as a valid grant.

The safer founder workflow is:

• Approve the plan by board resolution
• Approve each option grant in the proper corporate manner
• Issue a signed grant agreement
• Update the cap table and minute book immediately

This is where a lot of startups get sloppy. Then six months later they are in diligence and cannot prove what was approved, when it was approved, or whether enough shares were even reserved.

7. Coordinate tax, payroll, and securities law treatment

This is the part founders often underestimate.

CRA says a taxable benefit can arise when an employee exercises their options and acquires shares at less than fair market value, or when they dispose of option rights for gain. CRA also says the timing differs depending on whether the employer is a Canadian-Controlled Private Corporation (CCPC). Most startups are CCPCs. For a CCPC, the benefit is generally included when the employee disposes of the shares, meaning the employee does not pay tax when exercising.

That means your employee stock option plan is not just a legal template exercise. It touches tax, payroll, securities compliance, and cap table administration.

Common mistakes founders make with employee stock options

1. Creating no option pool until investors force the issue

That usually weakens your hiring story and puts you in a worse negotiation position.

2. Blindly accepting a huge 10% to 20% reserve

A pool that is larger than your real hiring needs creates unnecessary founder dilution. Carta explicitly warns that larger option pool increases can lower the price per share and increase investor ownership when negotiated as part of the pre-money.

3. Promising equity before the company has approved the plan

You do not want an employee thinking they were "given shares" when the company never properly approved an option grant.

4. Forgetting to reserve enough shares

Under the CBCA, if your articles limit authorized shares, the corporation must keep enough authorized shares reserved to satisfy granted options and rights.

5. Ignoring vesting mechanics

A startup employee equity plan without vesting is often just a future cap table problem.

6. Not keeping the minute book and cap table updated

If you want a clean financing process, your corporate records need to match your promises.

Final takeaway

A properly structured employee stock option plan does three jobs at once.

It helps you recruit.

It keeps the right people incentivized.

It makes investor diligence smoother.

For most startups, the practical path is to create a real option pool early, often around 10% as a starting point, get proper board approval, set a clear vesting schedule, document each grant carefully, and keep your cap table clean. The "10% reserve" is market practice, not magic. The right number is the one that fits your hiring plan and financing strategy.
