Employee Equity Offer Letter: Template and Key Terms for 2026

An employee equity offer letter is the part of a job offer that describes the equity a new hire will receive: award type, number of options, strike price, vesting and cliff, and exercise window. It doesn't grant the equity by itself. The grant happens when your board approves it under your equity incentive plan, and we think the letter should say so plainly.

Definition: An equity offer letter is a written offer of employment that summarizes a proposed equity award and states that the award is subject to board approval, the company's equity plan and a separate grant agreement.

The letter is a promise. The board grant is what makes it true.

Why an employee equity offer letter matters

A vague equity line in an offer feels harmless on the day it's signed. It tends to get expensive later, at the worst possible time: during diligence, or when someone leaves. A good letter does four jobs:

Alignment. It shows how equity fits into total compensation and ties the hire's upside to the company's growth.
Clarity. It sets expectations on vesting, exercise and ownership before anyone signs, which is when misunderstandings are cheapest to fix.
Legal protection. Clear language that the award depends on board approval and the plan documents reduces the risk of a later claim that the company promised more.
Investor readiness. Investors review offer letters and grant records in due diligence. Letters that match board minutes and the cap table signal a well-run company.

For the bigger picture on cash versus equity for early hires, see startup compensation and equity.

Key terms to include in an equity offer letter

Type of award. Incentive stock options (ISOs), non-qualified stock options (NSOs), restricted stock or RSUs. Carta notes that ISOs can be granted only to employees, so contractors and advisors receive NSOs or other awards.
Number of options. State the share count. You can add the percentage of fully diluted shares as context, but the share count is what the grant agreement will use.
Strike (exercise) price. For options, say the price will equal the fair market value on the date the board approves the grant, not the date of the letter.
Vesting schedule and cliff. Carta describes four years with a one-year cliff as the common default. Write it out in full, including the vesting commencement date.
Post-termination exercise period. State how long the employee has to exercise vested options after leaving.
Early exercise. Say whether the plan lets the hire exercise unvested options. If it does, unvested shares stay subject to a company repurchase right until they vest.
Acceleration. Many letters say whether any vesting accelerates on a sale (single trigger) or on a sale plus termination (double trigger), or state that there is none.
Tax note. Many companies tell the hire that equity has tax consequences and suggest a personal tax advisor.
Plan reference and at-will language. Letters typically reference the equity plan and confirm at-will employment where applicable.

Tax and legal rules that shape the offer

These rules come from the Internal Revenue Code and SEC rules and apply to US companies. As the IRS explains in Topic 427, exercising an NSO is generally taxed on the spread between fair market value and the strike price, while exercising an ISO is generally not ordinary income but can trigger alternative minimum tax.

Exercise price and 409A. Options priced below fair market value can create serious tax problems for the employee. Carta explains that noncompliant deferred compensation can trigger immediate taxation plus an additional 20 percent tax. An independent 409A valuation gives a presumption of reasonableness and is generally relied on for 12 months or until a material event. See our 409A valuation guide.
ISO requirements. Under Internal Revenue Code Section 422, an ISO needs an exercise price of at least fair market value at grant and cannot be exercisable more than 10 years after grant. For someone who owns more than 10 percent of the company's voting stock, Section 422 requires a price of at least 110 percent of fair market value and a term of no more than 5 years.
The $100,000 limit. Section 422(d) caps ISO treatment at $100,000 of stock (valued at grant) that first becomes exercisable in any calendar year. Anything above that is treated as an NSO.
The 3-month rule. Under Section 422, an ISO keeps its tax status only if it is exercised while the person is an employee or within 3 months after employment ends (1 year if employment ends because of permanent and total disability). A longer exercise window in the letter is allowed, but options exercised after 3 months are taxed as NSOs.
Restricted stock, early exercise and 83(b). If you offer restricted stock, or let the hire early exercise options, the hire may want to make a Section 83(b) election. The IRS instructions for Form 15620 state the election must be filed no later than 30 days after the property is transferred.
Early exercise and the $100,000 limit. Cooley GO notes that when options are early exercisable, the whole grant counts as first exercisable in the year of grant, so a large early-exercisable grant can push part of it into NSO treatment even though vesting is spread over four years.
Securities compliance. Private companies usually rely on SEC Rule 701 for compensatory grants. The SEC says Rule 701 covers employees, consultants and advisors and requires extra disclosure if a company sells more than $10 million under the rule in a 12-month period.

Worked example: describing a grant clearly

Suppose you offer a senior engineer 40,000 options in a company with 10,000,000 fully diluted shares, and your latest 409A value is $0.50 per share. The grant size here is illustrative only. Real grants vary widely by stage, role and hire order: Carta's analysis of more than 8,000 grants to the first 10 hires at startups (June 2023 to June 2024) found a median of 1.49 percent for the first hire, with engineering roles often at the higher end.

Ownership context: 40,000 divided by 10,000,000 is 0.4 percent of fully diluted shares today.
Cost to exercise all options: 40,000 times $0.50, or $20,000.
Vesting: 10,000 options vest at the one-year cliff, then about 833 options vest each month for the next 36 months.
ISO limit check: the options are valued at $20,000 at grant, well under the $100,000 annual limit, so they can all qualify as ISOs, even if the letter offers early exercise and the full grant counts in year one.

Be careful about quoting a "paper value" based on your last preferred stock price. Preferred shares carry rights common stock doesn't, which is why the 409A price is usually lower. Explaining the difference serves the hire better than a flattering number they'll later feel misled by.

"Candidates understand percentages. Why not just offer one?"

It's tempting. "You'll get 0.5 percent" is easier to grasp than a share count and a strike price, and a percentage feels more honest about what the equity is worth.

But Percentages move with every financing, every option pool top-up and every SAFE that converts. A letter that promises a percentage invites an argument about which denominator was meant, and when. Give the share count as the promise and the percentage as today's context, labeled as such. That's the version that survives the next round.

Common mistakes in equity offer letters

Promising a percentage instead of a share count. Percentages change with every financing; share counts don't.
Stating an exercise price before the board sets it. The price is fixed on the grant date, which can be weeks after the offer.
Letting grants slip. Offer letters that never become board-approved grants are a common diligence finding. Approve grants promptly, make sure they fit inside your option pool, and record them on the cap table. Promised equity that isn't on paper is one of the red flags we look for in our take on reading a cap table.
Offering ISOs to contractors. Under Section 422, only employees can receive ISOs. Our guide to advisory shares covers how advisors are usually compensated.

Hiring with equity as you scale

Equity offers get more complex as the team grows and each round resets the math. Founders in 1752vc's remote Accelerate program, which invests $100K at a valuation cap of up to $3.5M in early-stage startups ready to grow, get founder-led sales training and access to a network of 850+ investors as the team grows. In our view, pairing a clear offer letter with a solid equity incentive plan means less time fixing paperwork before your next round.

The bottom line

Write the share count, describe how the price will be set, spell out vesting and the exercise window, and get the board grant done quickly.

A handshake feels generous.

A signed grant is what an employee can actually keep.

Key takeaways

An equity offer letter summarizes a proposed award; the board grant and plan documents make it real.
A clear letter usually states the number of options, award type, strike price basis, vesting and cliff, exercise window, early exercise and acceleration.
Under Section 422, ISOs require an exercise price at or above fair market value, a term of 10 years or less, and are limited to $100,000 first becoming exercisable per year.
A current 409A valuation helps protect employees from penalty taxes on underpriced options.
Under IRS rules, restricted stock recipients who want an 83(b) election have 30 days from the transfer to file.

Frequently asked questions

What should an equity offer letter include?

In our view it should include the type of award, the number of shares, how the exercise price will be set, the vesting schedule, the post-termination exercise period, any acceleration, a tax advisory note and a statement that the grant is subject to board approval and the equity plan.

Is an offer letter enough to grant stock options?

No. Stock options are granted when the board (or its delegate) approves them under the company's equity plan, and the terms are set out in a grant agreement. The offer letter should describe the intended grant and say it is subject to that approval.

How is the strike price set in an equity offer letter?

The strike price is set on the date the board approves the grant, at the fair market value of the common stock on that date, usually based on a current 409A valuation. The offer letter should describe that method rather than quote a number, because the price can change between the offer and the board meeting.

How long do employees have to exercise stock options after leaving?

It depends on the plan, and three months is a common default. Section 422 requires ISOs to be exercised within three months of leaving employment to keep ISO tax treatment. A company can offer a longer window, but exercises after three months are taxed as non-qualified options.

Can employees early exercise stock options?

Only if the company's plan and grant agreement allow it. Early exercise lets an employee buy unvested shares, which remain subject to a company repurchase right if they leave. The employee usually files an 83(b) election within 30 days of exercise, and the whole grant counts toward the $100,000 ISO limit in the grant year.
