Employee Stock Option Plans, or ESOPs, have become an important part of employee compensation, particularly in start-ups. Instead of receiving the entire compensation in cash, employees may be given an opportunity to acquire company securities either free of cost or at a concessional price.
While ESOPs can give employees an opportunity to participate in the growth of a company, they also have important income-tax implications.
The Income Tax Department has explained the taxation of ESOPs under the Income-tax Act, 2025, as amended by the Finance Act, 2026. The tax treatment broadly operates at two stages: when the securities are allotted to the employee and when those securities are subsequently sold.
Why Do Companies Offer ESOPs?
ESOPs are generally used by companies as a tool to attract and retain talent. They also allow employees to have a stake in the company's performance, which can create a stronger incentive to contribute to its long-term growth.
The arrangement is particularly common among start-ups. Companies that may not have the financial capacity to offer very high salaries can use ESOPs as an additional component of employee compensation.
When Is ESOP Taxable?
When an employer provides securities to an employee under an ESOP, either free of cost or at a concessional rate , the benefit is treated as a perquisite for income-tax purposes.
The first tax event occurs when the securities are allotted. The perquisite is broadly calculated using the Fair Market Value (FMV) of the securities on the date of exercise, reduced by the amount actually paid by the employee.
Importantly, the FMV on the date of allotment is not the figure used for determining the perquisite. The relevant FMV is the value on the date the employee exercises the option.
Simple Example
Suppose an employee exercises 100 ESOPs when the FMV of each share is Rs 6,500, while the employee is required to pay Rs 500 per share.
The taxable perquisite would be:
- (Rs 6,500 − Rs 500) × 100 = Rs 6,00,000
Thus, Rs 6 lakh would be treated as the value of the ESOP perquisite.
How Is Fair Market Value Determined?
The rules provide different methods depending on whether the shares are listed or unlisted.
For listed shares, the FMV is generally determined using the opening and closing prices on the relevant stock exchange. Where shares are listed on more than one exchange, the exchange with the highest trading volume is considered.
If there is no trading on the date of exercise, the prescribed closing-price mechanism based on the nearest preceding trading date applies.
For unlisted shares, the value is determined by a merchant banker on the date of exercise or on an earlier prescribed date, subject to the 180-day limitation specified in the rules.
What Happens When Employees Sell ESOP Shares?
The tax story does not end once the perquisite is taxed.
When an employee subsequently transfers the securities received under an ESOP, any resulting gain is taxable under the head "Capital Gains." The applicable tax treatment depends on the nature of the security and the applicable holding period.
There is an important distinction when calculating the holding period.
The holding period begins from the date of allotment of the securities, not from the date on which the employee exercised the ESOP.
At the same time, for calculating capital gains, the FMV on the date of exercise is taken as the cost of acquisition.
This means employees need to keep track of both the exercise date and the actual allotment date.
Special Tax Deferment for Employees of Eligible Start-Ups
The law provides a specific relief mechanism for employees of eligible start-ups.
Normally, the perquisite arising from ESOPs would result in tax/TDS implications even though the employee may not have received cash from selling the shares. This can create a cash-flow issue because the employee holds securities but may not have realised money from them.
To address this issue, the law provides for deferment of deduction and payment of tax on ESOP perquisites for eligible start-ups and their employees.
However, this benefit is specifically available only where the employer qualifies as an eligible start-up under the prescribed provisions.
When Does TDS Become Payable for Eligible Start-Up ESOPs?
For an employee of an eligible start-up, the employer is required to deduct tax from the ESOP perquisite within 14 days from the earliest of the following events:
- Expiry of 60 months from the end of the tax year in which the securities were allotted;
- The date on which the employee ceases to be employed by the organisation; or
- The date on which the employee sells the securities.
In other words, the deferment does not mean that the ESOP perquisite becomes permanently tax-free. It postpones the point at which the tax has to be deducted or paid.
Employees Still Need to Disclose the ESOP Perquisite
An important point for employees is that tax deferment does not eliminate the reporting requirement.
The value of the ESOP perquisite is required to be disclosed in the employee's return of income for the year in which the securities are allotted. However, where the deferment provisions apply, tax on that perquisite is not required to be paid in that year.
This distinction between reporting the income and payment/deferment of tax is important when preparing the tax return.
What If the Employee Continues Working and Does Not Sell the Shares?
The Income Tax Department's example illustrates how the deferred liability can eventually arise.
In the example, an employee receives ESOPs with a perquisite value of Rs 90 lakh , while salary excluding the ESOP perquisite is Rs 40 lakh. The employee is assumed to continue working with the company and retain the shares even after the 60-month period.
The employee discloses the Rs 90 lakh perquisite in the relevant year's return but does not pay tax on that perquisite in that year because of the deferment mechanism.
When the deferment period ends, the tax attributable to the ESOP perquisite becomes payable.
Key ESOP Tax Rules at a Glance
| Stage | Tax Treatment |
|---|---|
| ESOP granted/vested | Generally no immediate tax merely because the option is granted or vests |
| Exercise & allotment | Difference between FMV on exercise date and amount paid is treated as perquisite |
| Subsequent sale | Gain is taxable under Capital Gains |
| Capital-gains cost | FMV on date of exercise |
| Holding period | Starts from date of allotment |
| Eligible start-up employees | Eligible for prescribed deferment of TDS/tax payment |
| TDS trigger for eligible start-ups | Earlier of 60-month period, cessation of employment or sale |
| TDS timing | Within 14 days of the relevant triggering event |
The above treatment is based on the Income Tax Department's explanatory document and should be read along with the applicable provisions, rules and notifications. The document itself advises readers to verify the position from the relevant Government Acts, Rules and Notifications.
What Employees Should Keep in Mind
For employees holding ESOPs, the tax implications can be easy to overlook because the initial benefit is often received in the form of shares rather than cash.
The key dates and figures to track are:
- Date of exercise
- Date of allotment
- FMV on the date of exercise
- Amount actually paid for the securities
- Date of subsequent sale
- Applicable holding period
- Whether the employer qualifies as an eligible start-up
Understanding these details can help employees determine when the ESOP benefit becomes taxable and how a subsequent sale of the shares will be treated.
Conclusion
ESOPs can be an attractive component of employee compensation, but their tax treatment involves more than simply paying tax when shares are sold.
Under the current framework, the ESOP benefit is generally taxed as a salary perquisite, based on the FMV on the date of exercise, while a later sale can trigger capital gains taxation. For employees of eligible start-ups, a special mechanism can defer the deduction and payment of tax on the ESOP perquisite until specified trigger events occur.
For employees, founders and tax professionals, keeping the exercise, allotment and sale dates clearly documented is therefore essential for getting the ESOP tax treatment right.
