When you’re building a startup, cash is tight and competition for talent is fierce. How do you hire and keep great people when you can’t match corporate salaries?

That’s where EMI share options come in. EMI (Enterprise Management Incentives) is a UK government-approved scheme that lets startups grant employees the right to buy shares in the future at a fixed price. It’s designed for smaller, high-growth companies and comes with generous tax advantages for both employees and the business.

Put simply, EMI allows you to offer real ownership without needing to pay huge salaries upfront. Done right, it aligns your team with your growth journey, gives you a recruitment edge, and reassures investors that you’ve got proper incentives in place.

But EMI isn’t just about signing a few forms and handing out shares. The process has rules, deadlines, and common pitfalls that can trip founders up if they don’t prepare properly.

Here’s how the EMI process works – and the mistakes to avoid.

Step 1: Check if your startup qualifies

EMI (Enterprise Management Incentives) is designed for high-growth companies, but not everyone is eligible. To qualify:

• Your company must have gross assets of £30 million or less.
• You must have fewer than 250 full-time equivalent employees.
• You must carry out a qualifying trade (so certain activities like banking, farming, or property development are excluded).
• The employee being granted options must work at least 25 hours per week, or 75% of their working time for your company. They may not hold more than 30% of the company’s shares, nor options worth more than £250,000 at the time of the grant. 

Skipping this step is a classic mistake. If you don’t meet the criteria, HMRC can disqualify your scheme later, which means no tax reliefs for employees.

Step 2: Get a valuation agreed with HMRC

Before you issue options, you need to know what they’re worth. This isn’t about guessing – you need a formal valuation, usually with professional support, and you’ll submit it to HMRC for agreement.

Why it matters:

• Employees want reassurance that their options are priced fairly.
• Investors want confidence that your scheme is compliant.
• HMRC agreement protects everyone from future disputes.

A common mistake? Leaving this too late. HMRC valuations are only valid for 90 days, so timing is key.

Step 3: Design the scheme rules

EMI options are flexible – but that flexibility means you have to make choices. For example:

• Vesting: Will options vest over four years? With a one-year cliff?
• Exercise price: Will employees pay today’s market value, or a nominal amount?
• Good leaver/bad leaver rules: What happens if someone leaves early?
• Exit terms: Can options be exercised only on a sale, or earlier?

Founders often get caught by making schemes too generous or too complicated. The key is balance: attractive enough to motivate staff, simple enough to run without endless admin.

Step 4: Issue option agreements

Once the scheme rules are in place, each employee receives an individual option agreement. This sets out:

• How many options they’re being granted.
• Their exercise price.
• Vesting schedule and conditions.
• Circumstances under which options lapse.

This paperwork isn’t optional. Without properly signed agreements, your scheme doesn’t exist in the eyes of HMRC.

Step 5: Notify HMRC within 92 days

One of the easiest mistakes to make is missing the HMRC notification deadline. Every EMI option grant must be notified to HMRC within 92 days. Miss it, and the tax benefits disappear – no exceptions.

This is where having good processes or professional support makes all the difference.

Step 6: Manage and monitor the scheme

An EMI scheme isn’t “set and forget.” You’ll need to:

• Keep accurate records of option grants, exercises, and lapses.
• File an annual return with HMRC.
• Revisit your valuation if you issue new options later.

Investors will also want to see a clean option register during due diligence. Poor record-keeping is one of the biggest red flags in funding rounds.

Why EMI is worth the effort

Done right, EMI gives you three big advantages:

1. Talent magnet – You can compete with bigger salaries by offering meaningful ownership.
2. Retention tool – Vesting keeps people invested in your long-term success.
3. Tax efficiency – Employees get favourable tax treatment, and the company can claim corporation tax relief.

The setup takes effort, but the payoff is huge. A well-designed EMI scheme can define your culture, strengthen your hiring pitch, and reassure investors that your house is in order.

The bottom line

EMI isn’t something to wing or DIY. The process has strict steps, HMRC deadlines, and documentation requirements. Get it wrong, and you risk losing the very tax benefits that make EMI so powerful.

Get it right, and EMI becomes one of the most effective tools UK startups have for attracting, motivating, and retaining the talent they need to grow.
