7 ESOP Valuation Mistakes Indian Startups Make – and the Tax Liability Each Creates (2026)

By July 14, 2026Blog22 min read
ESOP Valuation
The most common ESOP valuation mistake — using a stale FMV certificate — can trigger TDS shortfall liability plus interest, even years after the exercise window closes.

ESOP valuation errors in India rarely surface immediately. They show up at the worst possible moment: during a funding round’s due diligence, in a tax notice three years after an exercise event, or when an employee files a complaint about incorrect TDS deduction. The Income Tax Act 2025 (effective April 1, 2026) tightened the valuation requirements further — including a hard 180-day FMV certificate validity rule under Rule 15, and extended tax deferral provisions that still do not eliminate employer TDS obligations. This guide covers the 7 mistakes RNC most frequently encounters, and what each one actually costs.

RNC has reviewed ESOP valuations where the wrong category of valuer was used, stale FMV was reused for exercise windows, and funding-round prices were applied as FMV — each creating regulatory exposure that the companies didn’t know they had until a notice arrived.
Income Tax Act 2025 — Effective April 1, 2026
Two ESOP-specific changes that affect every Indian startup with an active option pool

1. FMV validity rule tightened under Rule 15: The FMV certificate for unlisted shares at exercise must be obtained from a SEBI-registered Category I Merchant Banker and cannot be older than 180 days from the date of exercise. Not 181 days. This rule was previously under Rule 3(9)(ii) of the old IT Rules — now renumbered and restated under the Income Tax Act 2025.

2. Tax deferral extended from 48 to 60 months: Eligible DPIIT-recognised startups can defer ESOP perquisite tax for up to 60 months from the end of the tax year of allotment, or until the employee sells/leaves, whichever is earlier. The deferral applies to the employee’s cash payment — not to the employer’s TDS reporting obligation. This distinction is the source of one of the most common post-deferral compliance errors.

7 mistakes covered

  1. Using a stale FMV certificate for an exercise window
  2. Using the funding round price as ESOP FMV
  3. Using the wrong category of valuer for the wrong purpose
  4. Using the same valuation for accounting and tax purposes
  5. Not refreshing FMV after a significant funding event
  6. Assuming the tax deferral eliminates the TDS obligation
  7. Using the correct method for the wrong company stage
Mistake 1 — The most common
Using a stale FMV certificate for an exercise window

A startup completes a Series A round in January. The company gets an FMV valuation done for that transaction. Eight or ten months later, they open an ESOP exercise window. Someone in finance pulls out the January report and processes the exercises. The January report is now 250-plus days old — 70 days past the 180-day legal limit under Rule 15 of the Income Tax Rules 2026.

This is not a technicality. If the company’s fair market value at the time of exercise was actually higher than the January figure (which is likely after 8 months of operations), the TDS deducted on each exercise was short. The employer is liable for the TDS shortfall plus interest — and the Income Tax Department can reopen this even years after the exercise event.

Real pattern RNC encounters: A company opens an exercise window “urgently” before a Series B closes. The last valuation report is 200 days old. The company wants to use it to avoid the 2-week delay to get a fresh one. The correct answer is: pause the window. The cost of a 2-week delay is far lower than the TDS shortfall exposure on every single exercise in that window.
The fix

Commission a fresh FMV certificate at least 3-4 weeks before every planned exercise window opens. Build the valuation timeline into your exercise window planning calendar, not as an afterthought after you’ve told employees the window is open.

 

Mistake 2 — The most analytically wrong
Using the funding round price as ESOP FMV

This is the most analytically incorrect mistake, and it appears in two forms. The first: using the per-share price implied by a VC’s investment as the FMV for exercise pricing. The second: asking the VC’s own financial model team to produce the FMV figure as part of a due diligence deliverable, then reusing it for ESOP purposes.

Why this is wrong: Funding round valuations embed a premium for the specific class of securities issued to that investor — typically preference shares with liquidation preferences, anti-dilution protection, board seats, and other rights that ESOP holders do not have. The per-share price in a funding round does not represent the fair market value of the common equity underlying an ESOP. Applying it overvalues the ESOP, creating perquisite tax exposure for employees on a higher figure than the economic reality of their shares.

Post-2022 funding corrections have made this even more dangerous — employees who exercised based on peak-round FMV figures are now holding shares worth a fraction of what they paid tax on at exercise.

The audit risk: During an IPO or acquisition, the acquirer’s or underwriter’s due diligence typically reviews the ESOP valuation methodology used for historical exercises. Funding-round-price-as-FMV is flagged as a compliance gap and can delay closing or require remedial filing.
The fix

ESOP FMV must be an independent valuation of the common equity specifically, conducted by a SEBI-registered Category I Merchant Banker for tax purposes. It should explicitly account for the rights differential between preference share investors and common equity holders.

Used a funding-round price or stale valuation for a past exercise window? An independent FMV review can clarify your exposure.

Mistake 3 — The most regulatory
Using the wrong category of valuer for the wrong purpose

ESOP valuation in India touches two distinct regulatory frameworks — Income Tax and Companies Act — and each requires a different category of professional. Many companies satisfy one and not the other.

For Income Tax (Rule 15, Income Tax Act 2025): FMV at exercise must be determined by a SEBI-registered Category I Merchant Banker. An IBBI Registered Valuer’s report does not satisfy this requirement for tax purposes.

For Companies Act Section 247 (share allotment at exercise): An IBBI Registered Valuer is required. A merchant banker’s report does not satisfy this requirement for the allotment filing.

SEBI’s December 2025 amendment (effective January 2, 2026) added another dimension: sweat equity valuations for listed companies now require an IBBI Registered Valuer specifically — replacing the earlier merchant banker option for that purpose. The interaction between these three distinct requirements (Income Tax / Companies Act allotment / SEBI sweat equity) confuses even experienced finance teams.

The fix

Before opening any exercise window, map the specific regulatory trigger to the correct valuer category. For most unlisted company exercise windows: you need both a merchant banker report (for tax FMV) and an IBBI Registered Valuer certificate (for Section 247 allotment). Work with a firm that understands both requirements rather than assuming one report covers all purposes.

Mistake 4 — The accounting error
Using the same valuation report for both Ind AS 102 accounting and tax FMV

Ind AS 102 accounting and Income Tax FMV are two separate valuations answering two separate questions at different dates.

Ind AS 102 (accounting): Values the option itself (not the share) at the grant date, using Black-Scholes or Binomial models. The output is an accounting expense amortised over the vesting period. This grant-date figure does not change — it’s a fixed accounting entry.

Income Tax FMV (tax): Values the underlying share at the exercise date, specifically for computing the perquisite income of the employee at that moment. This is a current-market-value figure that changes every time you open a new exercise window.

Reusing the grant-date Ind AS 102 share FMV as the exercise-date tax FMV is incorrect whenever the company’s valuation has moved between grant and exercise — which is nearly always, given that most companies use their ESOP to attract employees during growth phases.

The fix

Maintain two separate valuation engagement tracks: a grant-date engagement covering the Ind AS 102 fair value of options (using Black-Scholes inputs), and an exercise-date FMV engagement for each exercise window. These are related but distinct assignments.

RNC Valuecon — Observations from ESOP Valuation Reviews

What we find when companies come to us after an exercise window

~40%

Of startups approaching RNC post-funding-round are still using a pre-round FMV for new exercise windows

3–4 wks

Typical lead time needed for a proper FMV engagement — most companies ask for it with less than 1 week to exercise window

1 in 5

Companies reviewed had a prior merchant-banker-only valuation being used for Companies Act allotment purposes — creating a Section 247 compliance gap

Mistake 5 — The timing error
Not refreshing FMV after a significant funding or corporate event

Even within the 180-day validity window, a FMV certificate can become effectively stale for good reasons: the company raised a new round, made a significant acquisition, lost a major client, or underwent a restructuring that materially changes its value.

Using a technically-valid-by-date-but-economically-stale FMV creates two risks. First, if FMV should be higher (post-growth event) the TDS is undercalculated — tax liability. Second, if FMV should be lower (post-correction), employees pay excess perquisite tax, creating employee relations problems and potential refund claims.

Common scenario: Series A closes in January (FMV ₹350/share). Company secures a marquee enterprise customer and grows MRR 3x. Exercise window opens in April — 90 days after valuation, so technically within 180-day limit. But the January FMV no longer reflects the company’s actual position. Using ₹350 as FMV now understates the perquisite value.
The fix

Trigger a fresh FMV engagement after any material corporate event — new funding round, significant revenue milestone, major customer win or loss, restructuring — regardless of whether the existing certificate is within 180 days.

Mistake 6 — The deferral misconception
Assuming DPIIT startup tax deferral eliminates the TDS obligation

The Income Tax Act 2025 extended the perquisite tax deferral for DPIIT-recognised startups from 48 months to 60 months from the end of the tax year of allotment (or until sale/departure, whichever earlier). This is genuinely helpful for employees who face a perquisite tax bill with no immediate liquidity to pay it.

The mistake: several founders and CFOs interpret this as meaning “if we’re DPIIT-recognised, we don’t have to worry about TDS at exercise.” This is incorrect. The deferral applies to the employee’s cash payment timeline — not to the employer’s TDS computation and reporting obligation. The employer must still compute the perquisite income, withhold the notional TDS liability, and report it correctly — even if the actual cash payment by the employee is deferred. Failure to correctly compute and report creates employer-side TDS proceedings, which are entirely separate from the employee’s deferral benefit.

The fix

Even if you’re DPIIT-recognised: commission a proper FMV at exercise, compute the perquisite income correctly, report the TDS computation accurately. The deferral changes when the employee pays — it does not change what the employer must report and when.

Mistake 7 — The method error
Using the right method for the wrong company stage

Not all FMV methods produce defensible results for all company types. The valuation method must match the company’s stage, structure, and purpose.

  • Pre-revenue or early stage: NAV or probability-weighted expected return methods are most appropriate. Applying a full DCF with projected revenues to a pre-revenue startup produces a number that an Assessing Officer can challenge for being speculative.
  • Post-Series A with revenue traction: DCF with market approach cross-check is appropriate. A simple NAV typically undervalues a company that has demonstrated revenue, as it ignores going-concern and intangible value.
  • Complex capital structure (SAFE, CCD, preference shares): Option pricing models (OPM) or probability-weighted expected return method (PWERM) are required to allocate value correctly across instrument classes. Using a simple share-price approach without accounting for liquidation preferences systematically overvalues the common equity underlying the ESOP.

The Income Tax Rules permit multiple methods — choosing the wrong one doesn’t automatically create a compliance violation, but it creates a defensibility problem when the Assessing Officer questions whether the method was appropriate for the company’s specific situation.

The fix

Method selection should be made by the valuer based on the company’s stage, capital structure, and the purpose of the valuation — not by the founder based on which method produces the most convenient number. Document the method selection rationale in the valuation report.

A Quick Self-Audit: Before Your Next Exercise Window

Run through this checklist before opening any ESOP exercise window:

  • Is the FMV certificate dated within 180 days of the planned exercise date? If not — stop and commission a fresh one before proceeding.
  • Is the FMV from a SEBI-registered Category I Merchant Banker (for Income Tax purposes) and separately from an IBBI Registered Valuer (for Section 247 allotment)?
  • Has the company had a material corporate event (new funding, major customer change, restructuring) since the last FMV? If yes — fresh FMV regardless of the date.
  • Does the FMV explicitly account for your capital structure’s liquidation preferences and anti-dilution provisions if you have preference shareholders?
  • If DPIIT-recognised and deferring employee tax payment — is the TDS computation and reporting still being done correctly on the company’s side?
  • Is the method selected appropriate for the company’s current stage (pre-revenue / traction / growth)?

Frequently Asked Questions

1. Can I use my company’s funding round valuation as the FMV for ESOP exercise?
No. Funding round valuations embed premiums for preference share rights that ESOP holders don’t have. Under Rule 15 of the Income Tax Rules 2026, FMV for unlisted shares at exercise must be independently determined by a SEBI-registered Category I Merchant Banker for that specific exercise event.
2. How long is an ESOP FMV certificate valid in India?
Under Rule 15 of the Income Tax Rules 2026 (effective April 1, 2026), the FMV certificate cannot be older than 180 days from the date of exercise — not 181 days. This is an absolute limit regardless of whether the company’s fundamentals have changed.
3. What happens if an exercise window uses a stale FMV?
If the actual FMV at exercise was higher than the stale figure, TDS was short — and the employer is liable for the TDS shortfall plus interest. The Income Tax Department can open TDS proceedings against the company years after the exercise event.
4. Who can perform the ESOP FMV valuation for Indian tax purposes?
For Income Tax FMV: a SEBI-registered Category I Merchant Banker. For Companies Act Section 247 share allotment: an IBBI Registered Valuer. These are different categories for different regulatory purposes — both are typically required for a standard exercise window.
5. What is the ESOP tax deferral for startups under the Income Tax Act 2025?
DPIIT-recognised startups can defer ESOP perquisite tax for up to 60 months (up from 48 months) from the end of the tax year of allotment, or until sale/departure. The deferral covers the employee’s cash payment — the employer’s TDS reporting obligation still applies in full.
6. What is the most common ESOP valuation mistake in India?
Using a stale FMV certificate — specifically, reusing a valuation report from a prior funding round or from more than 180 days before the exercise date. This is the most frequently seen error and the one most likely to trigger TDS liability.
7. Can I use my company’s funding round valuation as the FMV for ESOP exercise?
