- Exercise converts vested options into Equity Shares by paying the exercise price. Only then does the holder appear on the cap table.
- There are two windows. The in-employment window while the person is employed, and the post-termination period after they leave, both defined in the scheme.
- Cashless and net exercise remove the cash barrier. Full cashless sells shares to fund the price and tax; net exercise issues only the net gain shares.
- The exercise process is a fixed sequence: application, approval, payment, share issue, cap-table update, and perquisite TDS under Section 192.
- Record everything. Unexercised vested options lapse permanently, so notice, dates and register entries have to be clean.

What Exercise Actually Is
An ESOP exercise is the moment a vested option becomes a real share. Up to that point an employee holds only an option: a right to buy a fixed number of Equity Shares at the exercise price set at grant. When they exercise, they pay that price, the company allots the shares, and the employee moves from the option pool onto the cap table as a shareholder. Vesting earns the right; exercise takes it up.
Two things happen the instant an exercise completes, and both are the company’s responsibility. First, new Equity Shares are issued, so the cap table and the ESOP register both change. Second, a tax event is triggered: the gap between the fair market value on the exercise date and the exercise price is a perquisite taxed as salary, and the company must withhold TDS on it under Section 192. The employee side of that tax is covered in our guide to ESOP taxation in India; here we stay on what the company has to do to run the exercise cleanly.
Only vested options can be exercised, and only within the exercise window allowed by the scheme. Unvested options cannot be exercised, and vested options that sit past their window lapse. The window is therefore just as important as the vesting schedule that feeds it.
Setting the Exercise Window
An exercise window is simply the period during which a holder is allowed to exercise vested options. Every scheme really has two of them, and the terms are set at design time in the plan document. Get them explicit and you avoid the most common ESOP dispute: a leaver who believes they still had time to exercise.
- Runs while the person is still employed
- Many schemes allow exercise of vested options at any time
- Others open defined exercise windows (for example around a liquidity event)
- Employee chooses when, within the scheme rules
- Runs after the person leaves
- A fixed number of days to exercise options vested by the last day
- Commonly 30 days to a few months; sometimes longer for good leavers
- Vested options not exercised in time lapse to the pool
The post-termination exercise period is where founders have to make a real choice. A short window (say 30 to 90 days) is administratively simple and returns options to the pool quickly, but it can force a departing employee to fund the exercise price and the tax at the worst possible time. A longer window is kinder to leavers and increasingly expected, but it keeps the cap table open longer. Whatever you choose, define it once in the scheme, apply it consistently, and give every leaver written notice of their exact deadline. For how these windows connect to the underlying schedule, see designing the vesting schedule.
The clock on the post-termination window starts at the exit, so the exit calculation (vested versus lapsed) must be done immediately and accurately. If you settle the vested count late, the leaver’s window is already eating away, and a disputed date is exactly the kind of thing that surfaces in diligence.
Cashless and Net Exercise
The exercise price is a genuine barrier. An employee with a large vested grant may owe a real sum just to exercise, plus the perquisite tax, before they have seen a single rupee of gain. Cashless exercise and net exercise are the two ways companies remove that barrier, and it helps to be precise about the difference.
- Employee pays the full exercise price in cash
- Company issues all the shares exercised
- Simplest to account for; needs the employee to have cash
- Shares exercised and sold together, usually at a liquidity event or buyback
- Exercise price and tax deducted from proceeds
- Employee receives net cash, holds no shares
- Company issues only the net shares whose value equals the gain
- Shares equal to the exercise price are withheld, not issued
- Employee ends up holding fewer shares, pays no cash
In a full cashless exercise, the option is exercised and the shares are sold in the same transaction, typically only when there is liquidity, such as a secondary sale or a company buyback, so the exercise price and taxes come straight out of the sale proceeds and the employee never writes a cheque. In a net or net-settled exercise, there is no sale: the company simply issues fewer shares, keeping back the number of shares whose value equals the exercise price, so the employee receives the net gain in shares without paying cash. Net exercise is attractive because it lets employees exercise without a liquidity event, but it uses more of the pool per rupee of value and the accounting and valuation treatment should be confirmed with your auditor before you offer it.
“The exercise price stops more employees from exercising than founders realise. If you never plan for cashless or net settlement, you build a program people are proud of on paper and cannot afford to use.”
Ankit Sarawagi, Founder CFOmatrixThe Exercise Process a Company Runs
However the price is settled, the company runs the same underlying sequence. Treat it as a fixed process, not an ad hoc email thread, because each step creates a record the auditor and the next diligence team will ask for.
The tax step deserves its own attention: the perquisite is salary income, TDS runs under Section 192, and eligible DPIIT-recognised startups can defer that TDS under Section 192(1C). We cover the mechanics and the 48-month and specified triggers in employer tax and the DPIIT deferral. For the design decisions that sit upstream of exercise, the company-side ESOP administration pillar ties pool, vesting, valuation and reporting together.
Records to Keep
Exercise is the step diligence teams reconcile most closely, because it changes both the share count and the tax position. Every exercise should leave a clean, dated trail. Use this as an exercise-record checklist.
If the exercise workflow, the cap table and the register all live in one system with an audit freeze, an exercise is one reconciled transaction rather than three that someone has to line up by hand later. That is the difference between a clean data room and a scramble.
Send every leaver a single notice that states their vested count, their exercise window and its exact end date, and how to submit the exercise application. It cuts disputes and it is a document you will be glad exists if the date is ever questioned.

“Vesting earns the right; exercise takes it up. The company’s job is to make that step so clean that nobody argues about a date, a share count or a tax number afterwards.”
Ankit Sarawagi, CFOmatrixFrequently Asked Questions
What does exercising ESOPs mean?
Exercising is when an employee converts vested options into actual Equity Shares by paying the exercise price fixed at grant. Until exercise the employee holds only an option, a right to buy; after exercise they hold real shares and appear on the cap table. On the company side, exercise triggers a share issue, a cap-table update and a perquisite TDS obligation, because the difference between the fair market value on the exercise date and the exercise price is a taxable perquisite. Only vested options can be exercised, and only within the exercise window set by the scheme.
What is an ESOP exercise window?
An exercise window is the period during which a holder is allowed to exercise vested options. There are really two windows. The in-employment window runs while the person is still employed, and many schemes let employees exercise vested options at any time, or during defined open windows. The post-termination window runs after they leave, and is usually a fixed number of days within which they must exercise vested options or forfeit them. The scheme document defines both, and setting them clearly at design time avoids disputes later.
What is the post-termination exercise period?
The post-termination exercise period is the limited time after an employee leaves during which they can still exercise the options that had vested by their last day. Unvested options lapse on exit, and vested options must be exercised within this window or they lapse too. Companies commonly set it at anywhere from 30 days to several months, sometimes longer for good leavers, and the period is defined in the scheme. On the company side, the exit calculation fixes the vested count and starts the clock, so the window has to be tracked per leaver.
What is cashless exercise?
Cashless exercise lets an employee exercise options without paying the exercise price in cash out of pocket. In a full cashless exercise, shares are exercised and immediately sold, typically in a liquidity event or buyback, and the exercise price and taxes are deducted from the proceeds. In a net or net-settled exercise, the company issues only the net number of shares whose value equals the gain, keeping back enough shares to cover the exercise price rather than issuing all shares and collecting cash. Both remove the cash barrier that stops employees exercising.
What happens to unexercised options?
Options that are never exercised lapse. Unvested options lapse when an employee leaves. Vested options lapse if they are not exercised within the exercise window, whether that is the in-employment window or the post-termination period. Lapsed options generally return to the ESOP pool and can be regranted, depending on the scheme. Because a lapse is permanent, the company must give leavers clear notice of their window and record every lapse in the ESOP register, so the pool movement and the cap table both stay accurate.
How do I process an ESOP exercise?
The company runs a defined sequence: the employee submits an exercise application for a number of vested options, the company approves it and confirms the vested count and the fair market value, the employee pays the exercise price (or the exercise is settled cashless or net), the company allots the Equity Shares and updates the cap table and ESOP register, and it computes and deposits the perquisite TDS under Section 192. Every step should be documented. A tool like ESOP Flow runs this workflow, auto-generates the Exercise Application PDF and keeps the approval queue and records in one place.
