Employee stock option pool — sizing and ESOP trust setup for startups

Introduction

An Employee Stock Option Plan (ESOP) allows a startup to give employees the right to acquire shares of the company at a predetermined exercise price after satisfying specified vesting conditions. For startups, ESOPs can be an important tool for attracting senior talent, retaining key employees and aligning employees with long-term shareholder value.

For an Indian private limited startup, ESOPs are primarily governed by Section 62(1)(b) of the Companies Act, 2013 and Rule 12 of the Companies (Share Capital and Debentures) Rules, 2014. Rule 12 requires shareholder approval through a special resolution and prescribes disclosures relating to the ESOP scheme, vesting, exercise price, eligible employees and other terms.

A startup should decide two separate questions:

How large should the ESOP pool be?

Should the ESOP be implemented directly by the company or through an ESOP trust?

For most early-stage private startups, a direct ESOP structure is generally simpler. A trust can become useful where the company wants to acquire and hold shares in advance, facilitate secondary acquisition or create a more sophisticated employee-benefit structure.

1. What is an ESOP Pool?

An ESOP pool is a portion of the company’s equity reserved for future employee stock-option grants.

For example, assume:

Founder shares: 80%

Investor shares: 10%

ESOP pool: 10%

The 10% pool represents shares/options reserved for employees under the company’s ESOP scheme.

The pool can subsequently be allocated among:

Founders’ early employees

CXOs

Senior management

Key technical employees

Sales employees

Other eligible employees

The pool does not necessarily mean that all 10% shares have already been issued to employees. It may represent the equity reserved for future option grants.

2. How Large Should an ESOP Pool Be?

There is no universal statutory requirement that an Indian startup must create a particular percentage ESOP pool.

The appropriate size depends on:

Current employee count

Hiring plans

Stage of the startup

Expected future fundraising

Senior-management hiring

Existing employee grants

Investor expectations

Founder dilution tolerance

A practical planning range is often:

Startup Stage Indicative ESOP Pool

Very early / pre-seed 5–10%

Seed stage 8–12%

Series A 10–15%

Series B and beyond 10–15%+ depending on hiring needs

These are planning ranges, not legal requirements.

A startup should model the pool based on actual hiring requirements rather than automatically creating a 15% pool simply because that is common in venture transactions.

3. The 10% Pool Example

Suppose the company has:

10,00,000 fully diluted shares

and wants to create a:

10% ESOP pool

The company needs to determine whether the 10% is calculated on:

Existing issued shares; or

Fully diluted post-pool capitalisation.

This distinction is extremely important during fundraising.

If the pool is 10% of post-pool equity:

Existing shares = 10,00,000

Let ESOP pool = X.

Then:

X / (10,00,000 + X) = 10%

Therefore:

X = 1,11,111 shares approximately.

So the post-pool capitalisation becomes approximately:

11,11,111 shares

with:

Existing shareholders = 90%

ESOP pool = 10%

4. ESOP Pool vs ESOP Grants

These terms should not be confused.

ESOP Pool

Total equity reserved for employee options.

ESOP Grant

Specific options actually granted to an employee.

For example:

Company creates:

10% ESOP pool

but initially grants only:

2%

The remaining 8% remains available for future grants, subject to the scheme and approvals.

5. How Should the Pool Be Allocated?

A startup should ideally create a grant matrix before finalising the pool.

Example:

Position Indicative Equity Range

CTO / Technology Head 1%–3%

CFO / Senior Finance Head 0.5%–1.5%

VP / Business Head 0.5%–1.5%

Senior Engineer 0.1%–0.5%

Mid-Level Employee 0.03%–0.15%

Junior Employee 0.01%–0.05%

These are only illustrative ranges. Actual grants should depend on:

Seniority

Market compensation

Joining stage

Criticality of role

Existing salary discount

Expected contribution

Replacement cost

Fundraising stage

6. Don’t Give Away the Entire Pool at Once

One of the biggest mistakes startups make is allocating the entire ESOP pool immediately.

A better approach is to reserve part of the pool for:

Future senior hires

New business heads

Key technical hires

Retention grants

Promotion-based grants

Performance-based grants

For example:

10% Pool

4% — existing key employees

2% — future CXO hires

2% — future senior employees

1% — retention/performance grants

1% — contingency

This gives the founders flexibility during the next 2–4 years.

7. ESOP Vesting Structure

A common startup structure is:

4-Year Vesting

with:

1-Year Cliff

This means:

Employee receives the grant on joining.

No options vest during the first year.

At the first anniversary, 25% vests.

Remaining 75% vests monthly/quarterly over the next three years.

Example:

Employee receives:

40,000 options

Vesting:

10,000 options after Year 1

and the balance:

30,000 options over Years 2–4

The exact vesting schedule should be specified in the ESOP scheme and grant letter.

8. Minimum Vesting Period Under Companies Act

For an unlisted company governed by Rule 12, there must generally be a minimum one-year period between the grant of options and vesting, subject to the specific exception provided for options granted in certain merger/amalgamation situations.

Therefore, a startup should not structure an ordinary ESOP grant with immediate vesting contrary to this statutory requirement.

9. Exercise Price

The exercise price is the amount the employee pays to acquire the shares after the options vest.

For example:

Fair value/current valuation:

₹500 per share

Exercise price:

₹100 per share

Employee exercises:

10,000 options

Amount payable:

₹10 lakh

The potential economic benefit to the employee depends on the eventual value of the shares and applicable tax rules.

For unlisted companies, valuation and pricing should be properly documented. Rule 12 allows the company to determine the exercise price in accordance with applicable accounting policies.

10. ESOP Grant Does Not Mean Immediate Share Ownership

This is another important distinction.

At the option grant stage, the employee generally does not become a shareholder merely because options have been granted.

The employee normally becomes a shareholder after:

Options vest;

Employee exercises the options;

Exercise price is paid;

Shares are issued/allotted.

Rule 12 specifically provides that employees do not have shareholder rights such as voting or dividend rights in respect of options until shares are issued on exercise.

11. ESOP Approval Process for a Private Limited Company

For an unlisted private company, the typical process is:

Step 1 — Design the ESOP

Decide:

Pool size

Eligible employees

Vesting

Exercise price

Exercise period

Lock-in, if any

Lapse conditions

Exit treatment

Step 2 — Board Approval

The Board approves the proposed scheme and calls a general meeting.

Step 3 — Shareholder Approval

The ESOP scheme generally requires shareholder approval through a special resolution under Section 62(1)(b) and Rule 12.

Step 4 — Issue Grant Letters

Eligible employees receive individual grant documentation.

Step 5 — Maintain ESOP Register

The company should maintain proper records of:

Grants

Vesting

Exercise

Lapse

Cancellation

Shares issued

Step 6 — Exercise & Allotment

When employees exercise vested options, the company completes the applicable allotment and statutory filings.

12. What Must the ESOP Notice Disclose?

The explanatory statement accompanying the shareholder resolution should contain important details.

Rule 12 includes disclosures such as:

Total number of options

Classes of employees eligible

Eligibility/appraisal process

Vesting requirements

Vesting period

Maximum vesting period

Exercise price/formula

Exercise period

Exercise process

Lock-in period, if any

Maximum options per employee

Maximum aggregate options

Option valuation method

Circumstances in which options may lapse

Treatment on termination/resignation

Compliance with applicable accounting standards.

A well-drafted explanatory statement is therefore an important part of the ESOP implementation.

13. Additional Shareholder Approval

Separate shareholder approval is required in specified situations.

For example, Rule 12 provides for separate approval where options are granted to:

Employees of a holding or subsidiary company; or

Identified employees during a year in excess of the prescribed 1% of issued capital threshold, subject to the rule’s conditions.

The company’s cap table should therefore be reviewed before large grants are approved.

14. ESOP Trust — What Is It?

An ESOP trust is a separate trust established to facilitate an employee-benefit/share-based scheme.

Instead of the company implementing the scheme entirely on a direct basis, the trust can hold shares and/or undertake transactions for the purposes permitted under the applicable legal framework.

A trust-based structure is more sophisticated than a direct ESOP.

15. Is an ESOP Trust Mandatory?

No, not for every private startup.

A company can generally implement an ESOP directly, subject to the Companies Act and applicable rules.

A trust becomes relevant where the company wants a structure involving matters such as:

Holding shares for employees

Secondary acquisition of shares

Employee liquidity mechanisms

Promoter/shareholder contribution of shares

More sophisticated employee-benefit arrangements

For listed companies, SEBI’s share-based employee-benefit framework contains detailed provisions concerning trusts. SEBI’s regulations expressly recognise ESOS implementation directly or through an irrevocable trust and prescribe additional conditions for trust structures.

16. ESOP Trust vs Direct ESOP

Particular Direct ESOP ESOP Trust

Complexity Lower Higher

Setup cost Lower Higher

Administration Easier More involved

Shares held in advance Generally no Can be structured to hold shares

Secondary acquisition Limited / specific rules More suitable where legally permitted

Best suited for Early-stage startups Larger/more sophisticated plans

Trustee governance Not required Required

Documentation Moderate Extensive

For a small startup with 10–20 employees, a direct ESOP is often easier to administer.

17. Setting Up an ESOP Trust

Where a trust structure is selected, the company should generally work through the following stages.

Step 1 — Decide the Trust Structure

Determine:

Trust name

Purpose

Trustees

Beneficiary framework

Scheme relationship

Funding mechanism

Step 2 — Draft Trust Deed

The trust deed should clearly specify:

Purpose

Powers of trustees

Employee-benefit objectives

Shareholding powers

Acquisition/disposal powers

Governance

Trustee remuneration

Termination

Accounting

Reporting

Step 3 — Appoint Trustees

Independent and appropriate persons should be selected in accordance with the applicable framework.

Step 4 — Execute/Register Trust

The trust should be established and registered as required under the applicable state law and transaction structure.

Step 5 — Obtain PAN and Bank Account

The trust generally needs appropriate tax and banking registrations.

Step 6 — Fund the Trust

Funding arrangements must be structured carefully because Companies Act restrictions apply to financial assistance/share acquisition arrangements.

Step 7 — Acquire/Hold Shares

The trust can acquire or hold shares only within the legally permitted framework.

18. Section 67 Considerations

An ESOP trust cannot simply borrow unlimited money from the company and buy the company’s shares.

Section 67 of the Companies Act, 2013 contains restrictions on a company providing financial assistance for the purchase of its own shares, subject to specified exceptions and conditions.

The ICSI’s January 2026 guidance also highlights the requirement for member approval by special resolution and the application of Rule 16 for schemes involving provision of money for purchase/subscription of company shares.

Therefore, an ESOP trust should be structured only after reviewing:

Section 67

Rule 16

Section 62

Rule 12

Applicable accounting requirements

Tax implications

FEMA, where foreign employees/shareholders are involved

19. Trust Structure for Secondary Acquisition

One reason companies may consider a trust is to facilitate a secondary-acquisition model where the trust acquires existing shares for the employee scheme, where legally permitted.

This is particularly relevant to more mature companies.

However, a startup should not assume that a trust can freely purchase shares from founders or investors.

The transaction needs to be reviewed against:

Companies Act

Applicable rules

Shareholder approvals

FEMA, where relevant

Valuation requirements

Tax implications

Existing investor agreements

20. ESOP Trust for Private Companies vs Listed Companies

This distinction is important.

Private Company

Primarily governed by:

Companies Act, 2013

Companies (Share Capital and Debentures) Rules

Income-tax provisions

Accounting standards

FEMA, where applicable

Listed Company

Additional SEBI regulations apply.

SEBI’s framework specifically regulates share-based employee-benefit schemes involving listed companies and provides detailed requirements for trusts, secondary acquisition and other matters.

A startup planning to IPO should therefore review its ESOP structure before listing rather than waiting until the IPO process begins.

21. ESOP Taxation for Employees

ESOP taxation generally has two important stages.

Stage 1 — Exercise

When an employee exercises the option and shares are allotted, the difference between the prescribed fair market value and the exercise price can become taxable as a perquisite, subject to the applicable provisions.

Stage 2 — Sale

When the employee subsequently sells the shares, capital gains tax can arise based on the difference between:

Sale consideration; and

Applicable cost of acquisition.

Therefore:

ESOP taxation can occur both at exercise and at sale.

22. Startup ESOP Tax Deferral

Eligible employees of certain eligible startups can benefit from a special tax-deferral mechanism for the ESOP perquisite.

The Income Tax Department continues to recognise this special treatment; its current filing guidance specifically identifies taxpayers who have deferred income tax on ESOPs received from an eligible startup.

The benefit is subject to specific eligibility and timing conditions, so startups should verify whether they qualify before communicating tax benefits to employees.

23. Accounting Treatment

ESOPs also have an accounting impact.

Depending on the applicable accounting framework, the company may need to recognise share-based payment expense over the vesting period.

For example:

Grant-date fair value of options:

₹50 lakh

Vesting period:

4 years

The accounting expense may be recognised over the relevant vesting period, subject to the applicable accounting standard and detailed valuation methodology.

The accounting treatment should not be confused with the employee’s tax treatment.

24. ESOP Valuation

For an unlisted startup, valuation is particularly important.

Factors can include:

Latest funding round

Revenue

EBITDA

Growth rate

Comparable companies

Preference-share rights

Liquidation preferences

Company stage

Market conditions

Future projections

The valuation for accounting, tax and corporate-law purposes may not always be identical.

Therefore, startups should clearly identify:

Which valuation is being prepared?

For example:

ESOP accounting valuation

Tax FMV

Share issuance valuation

FEMA valuation

Fundraising valuation

25. ESOP Pool Dilution

Founders should understand that an ESOP pool creates potential dilution.

Suppose founders initially own:

100%

and create:

10% ESOP pool

The founders’ percentage ownership can fall to approximately:

90%

on a fully diluted basis, depending on how the pool is structured.

If an investor subsequently invests for another 20% post-money ownership, the founder’s percentage may dilute further.

Therefore, ESOP planning should always be integrated with the startup’s fundraising cap table.

26. ESOP Pool and Fundraising

Investors frequently examine the ESOP pool during a funding round.

The key question is:

Who bears the dilution created by the ESOP pool?

This can materially affect founder ownership.

Example

Before investment:

Founder = 90%

Existing ESOP = 10%

Investor wants 20% post-money.

If the investor requires an additional ESOP pool to be created before the investment, the founders can bear more of the dilution.

Therefore, founders should negotiate:

Existing pool

Required pool

Pool top-up

Pre-money/post-money treatment

Fully diluted share count

before signing the term sheet.

27. Example — ESOP Pool + Fundraising

Assume:

Founder shares = 90 lakh

Existing ESOP = 10 lakh

Total = 1 crore

Existing ESOP = 10%.

Now investor wants 20% ownership.

If the company first expands the ESOP pool to 15%, the cap table changes before the investment.

That additional 5% can create meaningful founder dilution.

Therefore, ESOP pool sizing is not just an HR decision—it is also a fundraising decision.

28. Recommended Startup ESOP Structure

For an early-stage Indian startup, a practical structure could be:

ESOP Pool

8–12%

Vesting

4 years

Cliff

1 year

Vesting Frequency

Monthly or quarterly after cliff.

Exercise Period

Clearly defined in the scheme.

Good Leaver

Longer exercise period / favourable treatment as permitted by the scheme.

Bad Leaver

More restrictive treatment.

Change of Control

Specify treatment of:

Accelerated vesting

Cash-out

Replacement options

Exercise before transaction

The exact terms should be customised rather than copied from another startup.

29. Documents Required

A proper ESOP implementation normally requires a document set including:

Corporate Documents

Board resolution

Shareholder special resolution

AGM/EGM notice

Explanatory statement

ESOP Documents

ESOP Scheme

Grant letter

Vesting schedule

Exercise notice

Exercise confirmation

Share certificate/allotment documents

Trust Documents, if applicable

Trust deed

Trustee resolutions

Company-to-trust arrangements

Share acquisition documents

Bank records

Trust accounting records

Compliance Records

ESOP register

Cap table

Valuation report

Accounting workings

ROC filings

Tax records

30. Common Mistakes Startups Should Avoid

❌ Creating a 20% Pool Without Modelling Dilution

The pool should be based on actual hiring requirements.

❌ Giving Options Without Shareholder Approval

The statutory approval process must be followed.

❌ Ignoring the One-Year Vesting Requirement

Rule 12 prescribes a minimum one-year period between grant and vesting, subject to its specified exception.

❌ Treating Options as Shares

An option holder is not automatically a shareholder.

❌ Setting Exercise Price Without Valuation Analysis

Pricing should be properly documented.

❌ Creating an ESOP Trust Too Early

A trust can add significant legal and administrative complexity.

❌ Ignoring Fundraising Dilution

ESOP pool sizing should be modelled together with the next funding round.

❌ Ignoring Tax at Exercise

Employees need to understand the potential perquisite-tax impact.

📊 Direct ESOP vs Trust — Which Is Better?

Factor Direct ESOP ESOP Trust

Early-stage startup ⭐⭐⭐⭐⭐ ⭐⭐

Simple employee grants ⭐⭐⭐⭐⭐ ⭐⭐

Low administration ⭐⭐⭐⭐⭐ ⭐⭐

Secondary acquisition ⭐⭐ ⭐⭐⭐⭐

Large employee base ⭐⭐⭐⭐ ⭐⭐⭐⭐

Sophisticated employee liquidity ⭐⭐ ⭐⭐⭐⭐

Setup cost Lower Higher

Legal complexity Lower Higher

Governance Simpler More extensive

Practical Recommendation

For most early-stage private startups:

Start with a well-designed direct ESOP scheme.

Consider an ESOP trust when there is a genuine business/legal reason for one, particularly around permitted share acquisition or a more sophisticated employee-benefit structure.

🏁 Conclusion

An ESOP pool is one of the most useful tools available to an Indian startup for attracting and retaining high-quality employees, but the pool should be designed as part of the company’s capitalisation and fundraising strategy, not merely as an HR benefit.

There is no universal statutory requirement for a startup to maintain a particular ESOP percentage. In practice, an early-stage company may consider a pool in the 5–10% range, while a company anticipating significant senior hiring may need 10–15% or more. The right number depends on the company’s hiring plan, stage, existing grants and expected fundraising.

For private companies, ESOP implementation is governed principally by Section 62(1)(b) and Rule 12, with shareholder approval through a special resolution and prescribed disclosures. Rule 12 also provides for a minimum one-year period between grant and vesting, subject to its specified exception.

An ESOP trust is not automatically required. For an early-stage startup with straightforward employee grants, a direct ESOP structure is usually simpler. A trust becomes more relevant where the company needs a permitted mechanism for holding/acquiring shares or implementing a more sophisticated employee-benefit structure. Where a trust is used, Companies Act restrictions—including those relating to financial assistance and acquisition of the company’s own shares—must be carefully reviewed.

Finally, founders should remember that ESOP pool sizing directly affects dilution. The pool should therefore be modelled alongside the next fundraising round, rather than decided independently by the HR team.
