Old vs New Tax Regime for ESOP-Heavy Salaried Employees — Complete 2026 Guide

Updated: June 2026 Tax Year 2026-27 ESOP Capital Gains

Reviewed by CA Nikhil Gupta · Last reviewed 26 September 2026

Corrected 26 September 2026: the earlier version showed a slab table that mixed the two regimes and said both regimes charge 30% above ₹15 lakh (the new regime reaches 30% only above ₹24 lakh); Rahul's case study used the wrong old-regime standard deduction and added a surcharge that did not apply, which reversed its conclusion; it cited Section 55(2) for the LTCG exemption (Section 198), gave the unlisted-share LTCG exemption in the Preethi example (it applies only to listed equity) and mis-stated the deferral period.

For startup employees and corporate executives with significant ESOP grants, the old vs new regime decision is far more complex than it is for a simple salaried employee. ESOPs create two tax events: first as a perquisite at exercise, then as capital gains at sale. The regime you choose affects the first event directly, and the timing of exercise can have a dramatic impact on your total tax bill. This guide unpacks both events, explains the regime impact, and gives you a planning framework to minimise your ESOP tax outgo.

The Two Tax Events in ESOPs

Employee Stock Option Plans in India create two separate tax events, taxed under completely different heads:

Event	When It Happens	Tax Head	Regime Impact
Exercise (convert option to share)	When you exercise your vested options and buy shares	Salary (Perquisite)	Yes — slab rate applies; regime affects your bracket
Sale (sell shares in market)	When you sell the shares received on exercise	Capital Gains (LTCG/STCG)	Minimal — CG rates are fixed regardless of regime

Event 1 — ESOP Exercise: Perquisite Tax

When you exercise your ESOPs (convert options into shares), the following is taxed as salary income (perquisite):

Perquisite Value = Fair Market Value (FMV) on Exercise Date − Exercise Price Paid

Your employer deducts TDS on this perquisite value in the month of exercise
This perquisite is added to your salary income for the year
Taxed at your applicable slab rate (this is where old vs new regime matters)
For listed shares: FMV = closing price on stock exchange on exercise date
For unlisted shares: FMV determined by merchant banker / SEBI-registered CA valuation

How Old vs New Regime Affects Exercise Tax

The perquisite is taxed at your marginal slab rate. Here's how the slabs differ for Tax Year 2026-27:

Income Slab	Old Regime Rate	New Regime Rate
Up to ₹2.5 lakh	Nil	Nil
₹2.5–4 lakh	5%	Nil
₹4–5 lakh	5%	5%
₹5–8 lakh	20%	5%
₹8–10 lakh	20%	10%
₹10–12 lakh	30%	10%
₹12–16 lakh	30%	15%
₹16–20 lakh	30%	20%
₹20–24 lakh	30%	25%
Above ₹24 lakh	30%	30%

Most ESOP-heavy employees are in the ₹20 lakh+ salary range. Above ₹24 lakh of taxable income both regimes charge 30% on the next rupee (the old regime reaches 30% at ₹10 lakh, the new regime only at ₹24 lakh) — so once total income is past ₹24 lakh, the perquisite is taxed at 30% under both regimes. The regime choice then matters more for the base salary deductions (HRA, 80C, etc.) and for whether they keep taxable income below the ₹50 lakh surcharge line than for the ESOP perquisite rate itself.

💡

Startup ESOP Deferral — old Section 192(1C), now within Section 392: For employees of DPIIT-registered startups, there's a significant benefit: TDS on ESOP perquisite is deferred until the earliest of: (a) expiry of 48 months from the end of the relevant year (under the 1961 Act, the assessment year of exercise), (b) date of sale of shares, or (c) date of leaving employment. This applies to ESOPs exercised in startups eligible for Section 80-IAC benefits. The tax liability itself is not waived — it's deferred. But deferral gives cash flow relief and time to sell shares first to fund the tax.

Event 2 — ESOP Sale: Capital Gains Tax

When you sell the shares acquired via ESOP exercise, capital gains tax applies. The cost of acquisition for CG purposes is the FMV on the date of exercise (not the exercise price you paid).

Share Type	Holding Period	Classification	Tax Rate (New Act)
Listed equity shares (on recognised exchange)	>12 months from exercise date	LTCG	12.5% on gains above ₹1.25 lakh/year (Section 198)
Listed equity shares (on recognised exchange)	≤12 months from exercise date	STCG	20% (flat, no slab)
Unlisted shares (private startup)	>24 months from exercise date	LTCG	12.5% without indexation (Budget 2024 change)
Unlisted shares (private startup)	≤24 months from exercise date	STCG	Slab rate (30% for most ESOP employees)

⚠️

Capital Gains Rates Are Regime-Agnostic: LTCG at 12.5% and STCG at 20% (for listed equity) apply regardless of whether you're in the old or new regime. The regime choice does not affect your capital gains tax rate. The only regime-related consideration is whether capital gains from ESOPs push your total income into a higher surcharge bracket.

Surcharge on ESOP Income — The Hidden Hit

ESOP perquisites (taxed as salary) can push high earners into surcharge brackets. The surcharge applies on the income tax payable:

Total Income	Surcharge Rate	Effective Tax Rate at 30% slab
₹50 lakh–₹1 crore	10%	33%
₹1 crore–₹2 crore	15%	34.5%
₹2 crore–₹5 crore	25%	37.5%
Above ₹5 crore	37% (old regime) / 25% (new regime)	41.1% (old regime) / 37.5% (new regime)

In the new regime, the surcharge on income above ₹5 crore is capped at 25% (effective rate 37.5% before cess), while the old regime allows up to 37% surcharge (effective rate 41.1% before cess). Rates in this table are before the 4% cess. For ultra-high-income ESOP employees, this is a genuine saving in the new regime even if regular deductions are less valuable.

Case Study: Rahul — Senior Engineer at a Listed Tech Company

Tech Lead, Bengaluru — Salary ₹30L, ESOP Exercise ₹25L Perquisite

Rahul has a basic + allowances salary of ₹30L. He exercises 5,000 ESOPs in April 2026 where FMV = ₹600/share and exercise price = ₹100/share. Perquisite = 5,000 × ₹500 = ₹25 lakh. His total income for Tax Year 2026-27: ₹30L + ₹25L = ₹55 lakh.

Old Regime: Deductions: HRA ₹3.5L, 80C ₹1.5L, 80D ₹25K, standard ₹50K = ₹5.75L. Taxable = ₹49.25L — below ₹50 lakh, so no surcharge. Tax at old slabs = ₹12.90L; with 4% cess ≈ ₹13.4L
New Regime: Only ₹75K standard deduction. Taxable = ₹54.25L. Tax at new slabs = ₹12.08L + 10% surcharge = ₹13.28L; with 4% cess ≈ ₹13.8L
Old regime saves ~₹40,000 for Rahul — his ₹5.25L of HRA, 80C and 80D deductions (the break-even is about ₹4.3L) pull taxable income below the ₹50 lakh surcharge line, which the new regime cannot do. With smaller deductions the result flips: at ₹2.5L of deductions the old regime would cost about ₹1.9L more.

He then sells these shares after 14 months (April 2027) at ₹800/share. CG per share = ₹800 − ₹600 = ₹200. Total LTCG = 5,000 × ₹200 = ₹10 lakh. After ₹1.25L exemption, taxable LTCG = ₹8.75L at 12.5% = ₹1.09L — same regardless of regime.

Case Study: Preethi — Startup Employee with Deferred ESOP Tax

Product Manager, DPIIT-registered Startup — Bengaluru

Preethi works at a DPIIT-registered startup. She exercises 10,000 ESOPs in May 2026 at ₹10/share. FMV at exercise = ₹500/share. Perquisite value = ₹49 lakh. Under old Section 192(1C) (now within Section 392), TDS on this perquisite is deferred.

The startup does NOT deduct TDS at the time of exercise (deferral applies)
5 years later (May 2031), Preethi sells shares at ₹1,200/share
Deferred perquisite tax (on ₹49L) becomes due in TY2031-32
LTCG = ₹1,200 − ₹500 = ₹700/share × 10,000 = ₹70L; no ₹1.25L exemption applies to unlisted shares: tax = ₹8.75L at 12.5%
Perquisite tax (₹49L at 30% + surcharge) = ~₹15–16L — payable in TY2031-32

Strategic Insight: Preethi can use sale proceeds to pay the deferred perquisite tax. Without deferral, she'd have had to pay ₹15L in tax in May 2026 when she had no liquidity (shares are unlisted). The deferral is a genuine cash-flow lifeline for startup employees.

Old vs New Regime Decision Framework for ESOP Employees

Your Situation	Likely Better Regime	Why
Income above ₹5 crore (surcharge-heavy)	New regime	Surcharge capped at 25% (vs 37% in old) — saves up to 3-4% on high ESOP income
Income ₹15L–₹50L with high HRA + 80C	Old regime	HRA + 80C + 80D deductions typically exceed new regime benefit in this range
ESOP exercise spikes income to ₹50L+	Compare carefully	Run numbers; new regime's lower slabs may compensate for lost deductions at high incomes
Startup employee — DPIIT startup, unlisted shares	Either (deferral more important)	Defer perquisite tax regardless of regime; compare regimes in the year tax actually falls due
Listed company ESOP, exercise year same as HRA rent city	Old regime often better	HRA + 80C + standard deduction creates large deductible base

ESOP Tax — Key Takeaways

ESOPs create 2 tax events: perquisite at exercise (salary income) + capital gains at sale
Perquisite = FMV on exercise date − exercise price; taxed at slab rate (old or new)
For incomes above ₹15L, both regimes are at 30% slab — regime choice matters mainly for deductions
New regime caps surcharge at 25% — significant saving if ESOP pushes income above ₹5 crore
Capital gains rates (12.5% LTCG, 20% STCG for listed) are same in both regimes
DPIIT startup employees: TDS on ESOP perquisite is deferred (old Section 192(1C), now within Section 392) — crucial cash flow benefit
For unlisted shares: LTCG (24+ months) = 12.5%; STCG = slab rate (potentially 30%)
Always run actual numbers — the better regime depends on the ESOP quantum vs deductions quantum

Frequently Asked Questions

ESOP exercise creates a perquisite taxed as salary income: FMV on exercise date minus the exercise price you paid. This is taxed at your applicable slab rate. For most ESOP employees with total income between ₹15–24L, new regime offers lower rates (20%–25%) vs old regime's 30% — regime matters significantly for the perquisite itself. The regime choice matters more for your base salary deductions (HRA, 80C, 80D). If your ESOP perquisite pushes total income above ₹5 crore, the new regime is better due to the surcharge cap at 25% (vs 37% old regime).

For listed company ESOPs: if shares are held more than 12 months from exercise date, LTCG applies at 12.5% on gains above ₹1.25 lakh/year. If held 12 months or less, STCG applies at 20%. For unlisted startup shares: if held more than 24 months, LTCG at 12.5% (without indexation, post Budget 2024). If held 24 months or less, STCG is taxed at your slab rate (30% for most ESOP employees). The cost of acquisition for capital gains is the FMV on the exercise date — not the exercise price you paid.

Yes. Under Section 392 of the Income Tax Act 2025 (the deferral was in Section 192(1C) of the 1961 Act), employees of DPIIT-registered startups eligible under Section 80-IAC can defer TDS on ESOP perquisite. The TDS becomes due at the earliest of: 5 years from the exercise date, the date of sale of shares, or the date of cessation of employment. This is not a waiver — the tax liability exists but you get cash flow relief. CBDT has prescribed a specific form for employers to record the deferral. Consult your startup's compliance team and CA to ensure proper documentation.
