Equity for Early Employees: Stock Options Explained
Equity is one of the few ways a young startup can compete with bigger employers for great people, and one of the most misunderstood parts of any job offer. This explainer covers how stock options work for early employees, from grant to vesting to exercise, in plain language, so founders can offer equity clearly and team members can understand what they are being offered.
Key takeaways
- A stock option is the right to buy shares later at a fixed price, called the strike or exercise price. It is not the same as owning shares today.
- Options usually vest over time. A common pattern is 4 years with a 1-year cliff.
- In the US, options are either ISOs or NSOs, and they are usually priced at fair market value based on a 409A valuation.
- In the UK, EMI options are the main tax-advantaged scheme for small companies.
- Exercising options and the taxes that follow can be complex, so everyone involved should get professional advice.
If you are a founder, you may be about to make your first equity grants and want to explain them well. If you are joining an early-stage company, you may be holding an offer letter that mentions "options" and wondering what they are worth. Either way, the basics are the same, and they are less mysterious than they first appear.
Please read this as general information, not tax, legal or investment advice. Equity rules and tax treatment differ by country and change over time, and personal situations vary a lot. Speak to a qualified tax adviser or lawyer before you grant, accept or exercise any options.
What a stock option actually is
A stock option gives you the right, but not the obligation, to buy a set number of company shares at a fixed price in the future. Four words do most of the work in any option grant:
- Grant. The moment the company formally gives you options, usually approved by the board and recorded in a grant agreement.
- Strike price. The fixed price you will pay per share if you buy. It is set on the grant date.
- Vesting. The schedule that decides when you earn the right to use your options.
- Exercise. Actually buying the shares by paying the strike price for vested options.
The idea is simple. If the company grows and its shares become worth more than your strike price, you can buy at the old, lower price. If the company does not grow, the options may end up worth nothing, and you simply choose not to exercise them.
Options vs shares
Holding options is not the same as owning shares. Until you exercise, you do not own any stock, you usually cannot vote and you do not receive anything if the company pays out to shareholders. Some early team members, often founders and very first hires, receive restricted stock instead, which is actual ownership from day one, subject to vesting. More on that below.
Common mistake
Judging an offer by the number of options alone. "10,000 options" means very little without knowing the total number of shares in the company, the strike price and the vesting terms. Always ask what percentage of the company the grant represents today.
How vesting works
Vesting protects the company and the rest of the team. It means equity is earned over time, so someone who leaves after a few weeks does not walk away with a large stake.
The cliff is a trial period for equity. If someone leaves before the first anniversary, they usually leave with no vested options. After the cliff, vesting continues in regular steps until the full grant has vested.
Questions to ask about vesting
- When does vesting start: on the start date or the grant date?
- Is there a cliff, and how long is it?
- Does vesting speed up if the company is sold? This is called acceleration, and terms vary.
- How long do you have to exercise vested options if you leave? This exercise window matters a great deal and is often short.
US options: ISOs vs NSOs
In the US, there are two main types of employee stock option. They differ mainly in how they are taxed, which is why the type on your grant matters.
| Incentive stock options (ISOs) | Non-qualified stock options (NSOs) | |
|---|---|---|
| Who can receive them | Generally employees; check current eligibility rules | Often more flexible; check current rules |
| Tax treatment | Can be more favorable if conditions are met, but has its own rules and traps | Generally simpler, with tax often due when you exercise |
| Complexity | Higher: holding periods and special tax calculations can apply | Lower, but the tax bill at exercise can surprise people |
Both types are usually priced at fair market value on the grant date, based on a 409A valuation. That is an independent valuation of the company's common stock, and it is the reason employee strike prices are often far lower than the price investors paid for preferred shares in a funding round.
The exact tax rules for ISOs and NSOs are detailed and change from time to time. Rather than relying on a summary, check the current IRS guidance and talk to a tax professional before you exercise.
Restricted stock and the 83(b) election
Founders and very early hires sometimes receive restricted stock instead of options. You own the shares from the start, but they are subject to vesting, which often means the company can buy back unvested shares if you leave.
In the US, people who receive restricted stock can file an 83(b) election with the IRS within 30 days of receiving it. The election changes when the stock is taxed, which can matter a lot if the company's value rises. The deadline is strict, so if restricted stock is part of your offer, speak to a tax adviser right away and do not leave it until after the holidays.
Pro tip
If you receive restricted stock near a holiday, put the 30-day deadline in your calendar the same day, along with a reminder a week before. Keep a copy of everything you file and proof that it was sent.
UK and Europe: EMI options and local schemes
In the UK, Enterprise Management Incentive (EMI) options are the main tax-advantaged option scheme for small companies. Companies and employees must meet eligibility conditions, and the scheme has its own rules about notifying the tax authority and valuing shares. When it fits, EMI can be a very attractive way to share ownership with a team.
Other European countries have their own option schemes and tax treatments, and the differences can be large. If you are building a team across several countries, plan your equity approach with an adviser who understands each place where your people live.
How founders can offer equity clearly
For founders, the goal is to make equity understandable, fair and properly documented. A clear explanation builds trust; a vague one creates resentment later.
- Set up an option pool. Work with your lawyer to reserve a portion of shares for employees, approved properly by the board.
- Get a valuation where required. In the US, a 409A valuation supports a fair strike price. In the UK, check the valuation process for EMI.
- Decide grants by role and stage. Earlier hires usually take more risk and often receive larger grants. Be consistent so similar roles get similar treatment.
- Explain the grant in plain language. Share the number of options, the percentage of the company today, the strike price, vesting terms and the exercise window.
- Put it in writing quickly. Document every grant with board approval and a signed grant agreement.
- Revisit the explanation each year. A short annual note on how equity works and what has changed keeps everyone informed.
An equity grant summary template
Share a simple summary like this with each team member alongside their formal paperwork. The figures are made up for illustration only.
| Team member | Options granted (example) | Approx. % today (example) | Strike price (example) | Vesting | Exercise window after leaving |
|---|---|---|---|---|---|
| First engineer | 40,000 | 0.8% | $0.20 | 4 years, 1-year cliff | Check your plan |
| First designer | 25,000 | 0.5% | $0.20 | 4 years, 1-year cliff | Check your plan |
| Operations lead | 15,000 | 0.3% | $0.35 | 4 years, 1-year cliff | Check your plan |
Hypothetical example
Imagine Sam joins a 6-person startup and receives 40,000 options with a made-up strike price of $0.20. Sam leaves after 8 months, before the 1-year cliff, so no options have vested. Now imagine Sam stays 2 years instead. With a 4-year schedule, half the options, 20,000, have vested. To buy them, Sam would pay 20,000 times $0.20, or $4,000, plus any tax that applies. Whether that is a good decision depends on the company's prospects and Sam's own finances, which is why advice matters before exercising.
What early employees should ask before signing
If you are on the receiving end, it is completely normal to ask questions. A good founder will be glad you did.
- How many shares are outstanding in total, so I can work out my percentage?
- What is the strike price, and when was the last valuation?
- Are these ISOs, NSOs, EMI options or another type?
- What is the vesting schedule, and is there acceleration?
- How long can I exercise after leaving?
- Can I see the option plan and my grant agreement before I start?
Your stock options action checklist
- Learn the four key terms: grant, strike price, vesting and exercise
- Confirm the option type: ISO, NSO, EMI or a local scheme
- Ask for the percentage of the company the grant represents today
- Note the vesting start, cliff, schedule and any acceleration
- Check the exercise window if you leave
- Diary any 83(b) deadline the same day you receive restricted stock
- Keep copies of the plan, grant agreement and board approval
- Talk to a tax adviser before exercising or filing elections
Frequently asked questions
Are stock options worth anything?
They can be, but only if the company's shares become worth more than your strike price and there is eventually a way to sell them, such as an acquisition or a public listing. Many startups do not reach that point, so treat options as a possible upside, not guaranteed pay.
What happens to my options if I leave the company?
Unvested options are usually lost. Vested options typically have to be exercised within a set window after you leave, or they expire. Check your option plan and grant agreement for the exact terms.
Do I pay tax when I receive stock options?
It depends on the type of option and where you live. Tax often comes into play at exercise or sale rather than at grant, but the rules vary, so check with a tax professional before taking any step.
Can contractors and advisors receive options?
Often yes, though the type of option they can receive may differ from what employees get, because eligibility rules vary by option type and by country. Check the current rules with your lawyer before making any grant.

The bottom line
Stock options give early team members a share in the value they help create. Understand the grant, the strike price, the vesting schedule and the exercise window, know which type of option is involved, and keep everything documented.
As the year winds down, it is a good moment for founders to write a one-page equity explainer for the team, and for employees to reread their grant paperwork with fresh eyes. Clear equity builds trust, and trust is what keeps a small team together.
