ESOP Taxation Under Income-tax Act 2025: Rules & Examples

ESOP TAXATION · EMPLOYEE STOCK OPTIONS

They look like an ownership opportunity. But an ESOP can create a tax bill long before the shares put any cash in your hands.

Grant → Exercise → Taxable Perquisite → Sale → Capital Gains

ESOP Taxation Under Income-tax Act 2025 is an important consideration for employees receiving stock options, particularly those working with eligible start-ups.

Quick Answer: How Are ESOPs Taxed Under the Income-tax Act, 2025?

When specified securities or sweat equity shares are allotted or transferred by an employer at a concessional price, the resulting benefit can be taxable as a salary perquisite under Section 17(1)(d).
The perquisite value is determined using the fair market value (FMV) on the date the option is exercised, reduced by the amount actually paid by or recovered from the employee.
For an eligible start-up, Section 392(3) links the deduction/payment mechanism to Section 289(3).
Under Section 289(3), the relevant tax or interest covered by the provision becomes payable within 14 days after the earliest of: expiry of 60 months from the end of the relevant tax year, sale of the securities, or cessation of employment with the employer that allotted/transferred them.
On a subsequent sale, the resulting gain or loss is considered under the capital gains provisions. For specified securities or sweat equity shares covered by Section 17(1)(d), Section 73 provides that the cost of acquisition is the FMV taken into account for the Section 17(1)(d) perquisite.

Introduction

Employee Stock Option Plans (ESOPs) are widely used by companies, particularly start-ups and growing businesses, to attract and retain employees.

Instead of receiving only cash compensation, an employee may receive an option to acquire shares or specified securities of the employer at a predetermined price. If the company’s value increases, the employee may ultimately benefit from the difference between the acquisition cost and the market value or sale price.

But ESOP Taxation Under Income-tax Act 2025 is more complicated than simply taxing the eventual profit on sale.

Under the Income-tax Act, 2025, the tax treatment generally involves two distinct stages:

Stage 1 — ESOP Perquisite

The benefit associated with specified securities or sweat equity shares can be taxable as a salary perquisite.

Stage 2 — Capital Gains

A later sale or transfer of the shares can result in capital gains or capital loss.

The new Act also contains a special timing mechanism for employees of eligible start-ups.

What Is an ESOP?

An Employee Stock Option Plan (ESOP) is an arrangement under which employees are granted an option to acquire shares or specified securities of the employer at a predetermined price.

The employee generally does not become the shareholder merely because an option has been granted.

Grant → Vesting → Exercise → Allotment/Transfer → Holding → Sale

The tax consequences depend on the relevant stage and the nature of the transaction.

The Income-tax Act, 2025 deals with the relevant concepts relating to options and specified securities within Section 17. Section 17(1)(d) specifically covers the value of specified securities or sweat equity shares allotted or transferred by the current or former employer, free of cost or at a concessional rate.

Is an ESOP Taxable at the Time of Grant?

Generally, the mere grant of an ESOP option does not mean that the employee has received the taxable share benefit contemplated by Section 17(1)(d).

An option is essentially a right given to the employee to apply for specified securities or sweat equity shares at a predetermined price. The employee may subsequently exercise that right subject to the terms of the ESOP.

Important: The grant and vesting stages should not automatically be treated as equivalent to the taxable perquisite event.

The important tax calculation arises when specified securities or sweat equity shares are allotted or transferred at a concessional price, with the value of the benefit determined using the statutory FMV mechanism.

ESOP Taxation Under Income-tax Act 2025: How Is ESOP Taxed?

Section 17(1)(d) brings within the salary-perquisite framework the value of specified securities or sweat equity shares allotted or transferred, directly or indirectly, by the current employer or former employer, free of cost or at a concessional rate.

The valuation mechanism is then applied to determine the taxable benefit.

ESOP Perquisite = FMV on Exercise Date − Amount Actually Paid or Recovered

The resulting perquisite forms part of the employee’s taxable salary income, subject to the applicable provisions of the Act.

Example

Exercise price: ₹100 per share

FMV on relevant exercise date: ₹500 per share

Number of shares: 1,000

(₹500 − ₹100) × 1,000 = ₹4,00,000

The ₹4,00,000 represents the ESOP-related perquisite value for income-tax purposes.

How Is ESOP Perquisite Calculated?

The basic calculation can be represented as:

ESOP Perquisite = FMV on Exercise Date − Amount Paid/Recovered

For multiple shares:

Taxable ESOP Perquisite = (FMV − Exercise Price) × Number of Shares

Example: 2,000 ESOP Shares

Exercise price: ₹50

FMV: ₹350

Number of shares: 2,000

Perquisite per share:

₹350 − ₹50 = ₹300

Total perquisite:

₹300 × 2,000 = ₹6,00,000

How Is Fair Market Value Determined?

The FMV of an ESOP security is important because it directly affects the amount of taxable perquisite.

The Income-tax Act, 2025 provides for FMV to be determined in accordance with the prescribed method.

The Income-tax Rules, 2026 provide the valuation framework for specified securities covered by Section 17(1)(d). Broadly, the prescribed methodology distinguishes between listed and unlisted securities.

Listed Equity

The prescribed market-price methodology applies, subject to the conditions in the rules.

Unlisted Equity

The prescribed valuation may require determination by a Merchant Banker.

Other Securities

The rules provide specific valuation requirements for specified securities other than equity shares.

Do not assume: The company’s internal valuation, funding valuation or last investment round automatically represents the tax FMV.

Why Can ESOPs Create a Tax-without-Cash Problem?

One of the biggest practical challenges with ESOP taxation is that the employee can have a taxable benefit without receiving cash.

Consider an employee who exercises options when the shares have an FMV of ₹1,000 but pays only ₹200 per share.

₹1,000 − ₹200 = ₹800 taxable benefit per share

However, the employee may not sell the shares immediately.

Key cash-flow issue:
Taxable benefit ≠ Cash received

This can create a cash-flow problem, particularly for employees holding shares in private companies or start-ups where there may be no immediate market or liquidity event.

Special ESOP Provision for Eligible Start-Ups

The Income-tax Act, 2025 provides a special timing mechanism for certain employees of eligible start-ups.

Section 392(3) applies where an eligible start-up referred to in Section 140 is responsible for paying income of the nature specified in Section 17(1)(d).

The provision states that the eligible start-up shall deduct or pay, as applicable, tax on that income based on the rates in force for the tax year in which the specified security or sweat equity share is allotted or transferred, within the time specified for the payee under Section 289(3).

This is not a permanent exemption.
It is a special statutory timing mechanism for deduction/payment of tax relating to the ESOP perquisite.

The special provision therefore cannot be assumed to apply merely because a company describes itself commercially as a start-up. The statutory eligibility requirements under Section 140 need to be considered.

What Is the 60-Month Rule?

Section 289(3) provides a specific rule for the timing of payment in eligible-start-up ESOP cases.

Where the specified conditions are satisfied, the relevant tax or interest included in the notice of demand is payable within 14 days after the earliest of the following events:

1. Expiry of 60 Months

60 months from the end of the relevant tax year.

2. Sale of the Shares

The sale of the specified security or sweat equity share.

3. Cessation of Employment

The employee ceases to be an employee of the employer that allotted or transferred the security.

60 Months from End of Tax Year | Sale | Employment Cessation
Whichever Occurs Earliest

Important: The statutory period is not simply “five years from the exercise date.” Section 289(3) specifically refers to 60 months from the end of the relevant tax year.

When Does the Deferred Payment/Deduction Mechanism Apply?

It is better not to describe this provision as a blanket “five-year ESOP tax exemption” or as a permanent tax deferral.

The more accurate description is:

Special statutory timing mechanism for deduction/payment of ESOP-related tax for eligible start-ups

Section 392(3) connects the eligible start-up’s obligation to the timing specified for the payee under Section 289(3).

The following conditions therefore matter:

The employer must qualify as an eligible start-up referred to in Section 140.
The income must be of the nature specified under Section 17(1)(d).
The security must have been allotted or transferred by the relevant employer.
The statutory trigger under Section 289(3) must be considered.

Example of the 60-Month Rule

Illustration

Assume an employee works for an eligible start-up and receives specified securities during a particular tax year.

Suppose the relevant tax year ends on 31 March 2027.

Sixty months from the end of that tax year takes the statutory period to 31 March 2032.

If the employee sells the shares in 2029, the sale can trigger the payment mechanism earlier.

Similarly, if the employee ceases employment in 2030, cessation can trigger it earlier.

Statutory Trigger = Earliest of 60 Months, Sale or Employment Cessation

What Happens If the Employee Leaves?

Leaving the eligible start-up can be significant for ESOP tax purposes.

Cessation of employment with the employer that allotted or transferred the specified security or sweat equity share is one of the specified triggering events under Section 289(3).

Employees should not assume that the special ESOP timing mechanism continues simply because the shares have not yet been sold.

The employee should review:

date employment ceased;
tax year in which the ESOP benefit arose;
FMV used for the perquisite;
amount paid for the shares; and
applicable tax-payment requirements.

What Happens When the Employee Sells the Shares?

The sale of ESOP shares is a separate tax event.

Once the employee sells the shares, the resulting gain or loss is considered under the applicable capital-gains provisions.

Capital Gain/Loss = Sale Consideration − Cost of Acquisition − Eligible Adjustments, as applicable

The crucial point is that the cost of acquisition for specified securities or sweat equity shares covered by Section 17(1)(d) is specifically addressed by Section 73.

Cost of Acquisition of ESOP Shares

Section 73(1), Table Serial No. 4 of the Income-tax Act, 2025 provides that for a capital asset being specified security or sweat equity shares referred to in Section 17(1)(d), the cost of acquisition is the FMV taken into account for the purposes of Section 17(1)(d).

Cost of Acquisition = FMV Taken into Account Under Section 17(1)(d)

For example:

FMV considered for ESOP perquisite = ₹500
Employee’s exercise price = ₹100
Later sale price = ₹800

The ESOP perquisite is based on:

₹500 − ₹100 = ₹400 per share

For the subsequent capital-gains calculation, Section 73 uses the FMV taken into account for Section 17(1)(d) as the cost of acquisition.

ESOP Taxation Example

Example: From Exercise to Sale

Particulars	Amount
Number of ESOP shares	1,000
Exercise price per share	₹100
FMV on exercise date	₹600
Later sale price	₹900

Step 1: ESOP Perquisite

(₹600 − ₹100) × 1,000 = ₹5,00,000

Step 2: Cost of Acquisition

₹600 × 1,000 = ₹6,00,000

Step 3: Later Capital Gain

₹900 × 1,000 − ₹600 × 1,000 = ₹3,00,000

The actual tax payable on the capital gain depends on the applicable capital-gains provisions, including the relevant holding-period and rate rules.

Exercise vs Sale of ESOPs

One of the most common ESOP tax mistakes is treating exercise and sale as the same tax event.

Exercise / Allotment-Related Benefit

The statutory valuation looks at the FMV on the exercise date and reduces it by the amount paid or recovered from the employee.

→ Salary Perquisite

Subsequent Sale

The later transfer can result in a capital gain or capital loss based on the sale consideration and statutory cost of acquisition.

→ Capital Gains

For eligible-start-up employees, the Act additionally provides a special timing mechanism for the deduction/payment of the relevant tax.

Old Income-tax Act, 1961 vs Income-tax Act, 2025

Important: Readers may encounter older ESOP articles using provisions of the Income-tax Act, 1961. Those references should not automatically be carried forward into the Income-tax Act, 2025.

Issue	Earlier Framework	Income-tax Act, 2025
ESOP / sweat equity perquisite	Section 17(2)(vi)	Section 17(1)(d)
Eligible start-up tax provision	Section 192(1C)	Section 392(3)
Start-up eligibility	Section 80-IAC framework	Section 140
Deferred-payment trigger	48 months under old provision	60 months under Section 289(3)
Time terminology	Assessment-year terminology	Tax-year terminology
Cost of acquisition	Earlier framework	Section 73, Table Sl. No. 4

Common ESOP Tax Mistakes

Assuming ESOPs Are Tax-Free

The ESOP perquisite and subsequent capital gain are separate tax considerations.

Confusing Grant With Taxable Benefit

The grant of an option should not automatically be equated with the taxable benefit under Section 17(1)(d).

Using the Wrong FMV

Tax FMV should be determined using the applicable prescribed valuation mechanism.

Using the Old 48-Month Rule

The new Act refers to 60 months from the end of the relevant tax year.

Assuming Every Start-Up Qualifies

The special provision applies to an eligible start-up referred to in Section 140.

Ignoring the Sale Stage

A subsequent sale can create a separate capital-gains consequence.

Frequently Asked Questions

Are ESOPs taxable under the Income-tax Act, 2025?

Yes. Section 17(1)(d) covers the value of specified securities or sweat equity shares allotted or transferred by the current or former employer, free of cost or at a concessional rate.

Is ESOP taxable at the time of grant?

The mere grant of an option should not be confused with the taxable perquisite arising from the allotment or transfer of specified securities or sweat equity shares. The statutory valuation is linked to the exercise date.

How is ESOP perquisite calculated?

Broadly: FMV on exercise date minus the amount paid or recovered from the employee.

What is the 60-month ESOP rule?

For the eligible-start-up provision, Section 289(3) provides that the relevant tax or interest covered by the provision is payable within 14 days after the earliest of expiry of 60 months from the end of the relevant tax year, sale of the security, or cessation of employment with the relevant employer.

Is the 60-month period counted from the exercise date?

No. Section 289(3) specifically refers to 60 months from the end of the relevant tax year.

What happens if an employee leaves the start-up?

Cessation of employment with the employer that allotted or transferred the specified security or sweat equity share can be one of the earliest triggers under Section 289(3).

What happens when ESOP shares are sold?

The subsequent sale can result in capital gains or capital loss under the applicable provisions.

What is the cost of acquisition of ESOP shares?

For specified securities or sweat equity shares referred to in Section 17(1)(d), Section 73 provides that the cost of acquisition is the FMV taken into account for the purposes of Section 17(1)(d).

Does every start-up get the ESOP tax timing benefit?

No. The provision refers specifically to an eligible start-up under Section 140.

Is the old 48-month ESOP rule still applicable?

The 48-month reference belongs to the earlier Income-tax Act, 1961 framework. The Income-tax Act, 2025 uses the 60-month rule in Section 289(3) for the relevant eligible-start-up provision.

Final Takeaway

ESOP taxation under the Income-tax Act, 2025 should be understood as a sequence of separate tax consequences rather than a single tax event.

The key framework is:

Section 17(1)(d)
→ ESOP/sweat equity benefit treated as a salary perquisite

Section 17 valuation provisions
→ FMV on the exercise date less amount paid/recovered

Section 392(3)
→ special deduction/payment mechanism for eligible start-ups

Section 289(3)
→ relevant tax/interest payable within 14 days after the earliest specified trigger, including 60 months from the end of the relevant tax year, sale, or cessation of employment

Section 73
→ FMV taken into account for Section 17(1)(d) becomes the statutory cost of acquisition for the specified ESOP securities/sweat equity shares

The most important practical lesson for employees is simple: do not look only at the eventual sale price of the ESOP shares. The exercise/allotment-related perquisite, applicable FMV, employee’s status with the employer, eligible-start-up conditions and subsequent sale all need to be considered separately.
