Phantom Share Schemes In The UK: How They Work And Key Documents

If you’re building a startup, you’ve probably had the same conversation more than once: you want to attract great people, you want them to care about growth like founders do, but you don’t want to hand out real equity too early (or at all).

That’s where a phantom share scheme often comes in.

It can be a practical way to reward key team members with something that feels like equity upside, without actually issuing shares and dealing with dilution, voting rights, or a complicated cap table from day one.

But like any incentive plan, the details matter. A phantom share scheme is essentially a contract-based promise. If it’s drafted loosely (or bolted onto a business without thinking through leavers, funding rounds, or what happens on a sale), it can create real disputes later.

Below, we break down how phantom share schemes work in the UK, why startups use them, what the pros and cons are, and the key legal documents you should have in place to protect your business as you grow.

What Is A Phantom Share Scheme?

A phantom share scheme (sometimes called “phantom equity”) is a contractual incentive arrangement where you promise someone a cash payout that is linked to the value of your company’s shares (or to a value-growth formula), without actually issuing any real shares.

In plain English: your team member doesn’t become a shareholder, but they can share in the upside as if they were.

What Phantom Shares Are (And Aren’t)

• They are not real shares. No Companies House filings, no share certificates, no voting rights.
• They are a contractual right. The person’s entitlement comes from your scheme rules and their participation agreement.
• They are usually paid in cash. Commonly on an “exit” (sale), or on other “trigger events” you define.
• They don’t dilute existing shareholders. Because you’re not issuing real equity (though you are creating an economic obligation).

This makes phantom share schemes especially appealing when you’re early-stage, pre-investment, or you want to keep equity tightly held between founders and investors.

It also fits neatly alongside your core founder arrangements, like a Founders Agreement and (if you’ve already brought in multiple shareholders) a Shareholders Agreement, because phantom equity can sit “around” your cap table rather than inside it.

How Does A Phantom Share Scheme Work In Practice?

Most phantom share scheme structures follow the same basic pattern: you set the rules, you decide who can participate, and you define the events (and calculations) that trigger payment.

Here’s how it typically works for a UK startup.

1) You Define The “Phantom Units” And What They’re Worth

You might grant a participant:

• a number of “phantom shares” (e.g. 10,000 phantom shares), or
• a percentage entitlement (e.g. payout equivalent to 0.5% of equity value on exit), or
• a formula-based amount linked to growth (e.g. value above a hurdle).

Then you define the valuation method. Common approaches include:

• Exit value (sale price of the company, net of debt and costs);
• Fair market value based on an investor funding round;
• Board-determined value (often with guardrails to reduce disputes);
• Independent valuation (more objective, but can cost time/money).

2) You Set Vesting (So Rewards Are Earned Over Time)

Like real equity, phantom entitlements usually vest. This is a key business protection: it helps you avoid paying out someone who leaves after a few months.

Typical vesting mechanics include:

• Time-based vesting (e.g. 25% per year over 4 years);
• A “cliff” (e.g. nothing vests until 12 months of service);
• Milestone-based vesting (e.g. vesting on hitting revenue targets, product milestones, or funding events).

You’ll want these mechanics to align with your hiring strategy and your broader retention incentives, which are often documented through an Employment Contract (including bonus and incentive clauses) and the scheme documents themselves.

3) You Define Trigger Events (When Payment Happens)

The most common trigger event is an exit (like a sale of shares or sale of the business). But you can also define other triggers, for example:

• a major funding round;
• IPO/listing (less common for SMEs, but possible);
• dividend-equivalent payments (rare in early-stage startups, but sometimes used);
• company buy-back of the phantom units (again, only if you draft it properly).

Be careful here: the broader you make the triggers, the more likely you are to create a cash obligation at a time when you can least afford it (like right after a funding round when you’re scaling).

4) You Build In Leaver Rules

Leaver provisions are where schemes succeed or fail.

A good phantom share scheme will clearly state what happens if someone leaves:

• Good leaver (e.g. redundancy, long-term illness, death, mutual agreement) – do vested phantom units remain eligible?
• Bad leaver (e.g. resignation to join a competitor, dismissal for misconduct) – are unvested/vested entitlements forfeited?
• Notice periods and garden leave – do they affect vesting?

This is one of the reasons it’s risky to DIY these schemes with a quick template. If the leaver rules are ambiguous, you can end up in costly disputes right when you’re trying to move fast. Also note that, in practice, leaver outcomes and forfeiture provisions should be drafted and applied carefully (particularly for employees), to reduce the risk of challenges under contract and employment law.

Pros And Cons Of A Phantom Share Scheme For UK Startups

A phantom share scheme can be a great strategic tool, but it’s not “automatically” better than real equity. Here’s a balanced view from a small business perspective.

Pros

• No dilution of ownership. Founders and investors keep their actual shareholdings unchanged.
• No shareholder rights created. Participants don’t gain voting rights, information rights, or veto powers that could slow decisions.
• Cap table stays clean. This can make future investment and due diligence simpler, especially early on.
• Flexible design. You can tailor vesting, triggers, and payout calculations to match your business model.
• Can support retention. If structured with sensible vesting and leaver rules, it encourages key hires to stay through major growth milestones.

Cons

• It creates a future cash liability. On an exit (or other trigger), you’ll owe cash. If you don’t plan for it, it can reduce proceeds for founders or complicate deal negotiations.
• Tax is often less favourable than approved share schemes. Phantom payouts are commonly taxed more like earnings than share gains (more on this below).
• Perception issues. Some senior hires want “real equity” and may view phantom shares as less valuable unless explained well.
• Valuation disputes are common if drafting is vague. If the scheme says “we’ll decide value later”, you’re inviting disagreements.
• Deal friction risk. If you haven’t documented the scheme properly, a buyer or investor may require it to be clarified (or terminated) before completion.

If you’re trying to decide between phantom incentives and actual equity options, it’s worth considering whether a tax-advantaged plan could fit your growth stage, such as EMI options (where the eligibility criteria are met).

Tax And Legal Considerations (What Business Owners Need To Know)

Phantom share schemes sit at the intersection of company law, employment incentives, and tax. You don’t need to memorise legislation to use them well, but you do need to understand the practical risks.

Tax: Phantom Payouts Are Often Treated Like Income

In many cases, a phantom share payout will be treated as:

• employment income (rather than a capital gain), and
• subject to PAYE and National Insurance contributions (depending on the structure, the documentation, and the person’s status).

This can reduce the “headline” value of the incentive compared to real shares or options. It also means your company may have payroll reporting and withholding obligations when the payout happens.

That said, tax outcomes can be fact-specific, and different drafting and circumstances can produce different results. This is general information, not tax advice - before implementing a scheme (or promising specific net outcomes), it’s sensible to get advice from a suitably qualified tax adviser or accountant.

Employment Law: Incentives Must Be Clear And Fairly Applied

A phantom scheme is still an incentive arrangement connected to the employment relationship (even if you offer it to contractors).

Key pitfalls we see in practice include:

• unclear discretion (e.g. “we can cancel at any time” clauses that are too broad and lead to disputes);
• poorly defined performance metrics (if vesting depends on targets);
• inconsistent offers that create internal tension (especially once your team grows);
• termination and deduction risk if scheme terms aren’t aligned with employment contract principles (for example, where a reduction/forfeiture could be argued to be an unlawful deduction from wages or a breach of contract).

Often the cleanest approach is to ensure the phantom scheme documents work alongside your core employment terms, rather than contradict them. If you have incentive-related clauses, they should be consistent across the scheme and the Employment Contract.

Contract Basics Still Apply

Because phantom shares are contractual, the basics of contract enforceability matter. If your scheme is vague, internally inconsistent, or never properly accepted, you can end up with something that’s hard to enforce (or hard to defend).

It’s worth pressure-testing your documents against the fundamentals of a legally binding contract, including clarity of terms, proper acceptance, and certainty around consideration and trigger events.

Key Legal Documents For A Phantom Share Scheme (And What They Should Cover)

A phantom share scheme is only as strong as the paperwork behind it. If you want it to motivate your team and protect the business, you’ll typically need a small set of documents that work together.

Below are the key legal documents we usually recommend startups consider.

1) Phantom Share Scheme Rules (Plan Rules)

This is the backbone document. It sets out how the scheme operates across your business.

Your plan rules commonly cover:

• definitions (what counts as an “Exit”, “Trigger Event”, “Bad Leaver”, etc.);
• eligibility and how awards are granted;
• vesting mechanics (time-based and/or milestone-based);
• valuation and calculation method (and what happens if there’s a dispute);
• payment terms (timing, payroll deductions, net vs gross);
• company discretion (carefully drafted so it’s workable but not unfair);
• leaver provisions and forfeiture events;
• change of control / restructure provisions;
• tax assumptions and responsibilities.

One practical tip: draft the rules with future due diligence in mind. If you’re planning to raise money or sell the business, you want a buyer/investor to be able to read the scheme and quickly understand the liability.

2) Participation Agreement (Award Letter)

This is the document each participant signs. It ties them into the plan rules and sets their specific entitlement.

It often includes:

• the number of phantom units (or percentage) granted;
• the vesting schedule that applies to them;
• any role-specific milestones or KPIs;
• confirmation that the award is subject to the scheme rules;
• confidentiality around scheme terms.

This needs to be consistent with your other agreements. For example, if your participation agreement says vesting stops on notice, but the person’s contract says bonuses accrue through notice, you can end up in a messy argument.

3) Board / Shareholder Approvals (Company Resolutions)

Even though phantom shares aren’t real shares, you should still treat the setup as a serious company decision. Proper approvals help show the scheme was validly adopted and that directors considered the commercial impact.

Depending on your company’s constitution and any investor arrangements, you may need board approval and/or shareholder consent.

Practically, this is often documented using a Company Resolution that:

• approves the creation of the phantom scheme;
• approves the form of scheme rules and participation agreements; and
• authorises a director to sign and grant awards.

4) Updated Employment And Contractor Agreements (Where Needed)

Sometimes the scheme can sit completely separately from your employment contract. Other times, it’s better to expressly reference the scheme in the person’s contract (especially for senior hires).

Common clauses to review include:

• bonus / incentive clauses;
• confidentiality and IP ownership;
• restraints (where appropriate and enforceable);
• termination provisions and garden leave.

If you’re scaling, it’s usually worth standardising incentive language across your Employment Contract templates so the scheme doesn’t become a one-off negotiation every time you hire.

5) Execution Formalities (Signing Correctly)

When startups move quickly, documents are often signed casually or inconsistently. That’s risky with incentive schemes because disputes often arise years later, when memories have faded and the payout is significant.

Make sure your scheme documents are signed correctly, and consider whether any documents should be executed as deeds (depending on structure and advice). If you’re unsure, the practical guidance around executing contracts is a useful benchmark for getting formalities right.

6) Alignment With Your Existing Ownership Documents

Even though phantom shares don’t change ownership, they can still impact your shareholder dynamics and exit negotiations.

For example:

• A buyer may want to know whether phantom payouts come out before or after shareholder distributions.
• Investors may want clarity that the scheme won’t accidentally become a voting or control mechanism.
• Founders may want certainty about how much “pool” is allocated to phantom incentives.

This is why phantom arrangements should be considered alongside your Shareholders Agreement and any investor terms, so your business doesn’t end up with competing obligations.

Key Takeaways

• A phantom share scheme gives team members a contract-based entitlement linked to company value, without issuing real shares.
• Phantom schemes can be a strong fit for startups because they avoid dilution and keep your cap table clean, while still rewarding growth.
• The trade-off is that phantom schemes create a future cash liability, and payouts are often taxed more like income than capital gains.
• Clear drafting is crucial: your scheme should define valuation, vesting, trigger events, and good/bad leaver outcomes in plain, enforceable terms (and be drafted with employment-law and contract-law constraints in mind).
• The key documents typically include scheme rules, participation agreements, and appropriate company approvals, aligned with employment terms and existing ownership documents.
• If you’re considering alternatives, tax-advantaged equity incentives (where eligible) like options may be worth comparing before you commit to a structure.
