The Formula

FMV Determination — Listed vs Unlisted

TDS at Exercise — How Employers Handle It

The employer deducts TDS on the perquisite value by reducing the employee’s salary in the month of exercise. This is why Nikhil’s March salary was nearly zero — the ₹90,000 TDS on his ₹3,00,000 perquisite was recovered from his salary. The perquisite details appear in:

• Form 16 / Form 130 (from April 2026) — Part B, perquisites section
• Form 12BA — detailed statement of perquisites (annexed to Form 16)

Cost of Acquisition — The Most Important Point

Under Section 49(2AA) of the ITA 1961, the cost of acquisition for capital gains purposes is the FMV on the exercise date — not the exercise price. This is because you already paid tax on the (FMV − Exercise Price) difference as a perquisite. Using the exercise price would tax that gain twice.

Capital Gain = Sale Price − FMV at Exercise Date

Capital Gains Rates — Listed vs Unlisted

How Deferral Works

Under Section 192(1C) of the ITA 1961 (equivalent under ITA 2025), the perquisite tax at exercise is deferred — no TDS is deducted at the time of exercise. Instead, tax becomes due at the earliest of three events:

• 48 months from the end of the Assessment Year in which shares were allotted — e.g., allotted in AY 2026-27 → defer until March 31, 2031
• Date of sale of the shares
• Date of cessation of employment — leaving the company triggers immediate payment

Deferral Exit — Cessation of Employment Risk

When you leave a DPIIT-eligible startup, the deferred perquisite tax becomes due immediately — regardless of whether you have sold the shares or have the cash. This catches many startup employees off guard. Plan for this if you are considering leaving — either sell enough shares before resignation to fund the tax, or ensure you have liquidity to pay on the cessation date.

If you hold ESOPs from a foreign parent company (MNC subsidiary employees, Indian founders of US-incorporated companies), the tax and compliance requirements are significantly more complex.

Tax Treatment — Same Two-Stage Framework

• Perquisite at exercise: (FMV − Exercise Price) × Shares, converted at RBI TT buying rate on exercise date — taxed as salary
• Capital gains at sale: Sale price − FMV at exercise (both converted at respective RBI rates on respective dates)
• Foreign shares: 24-month LTCG threshold, 12.5% rate (no ₹1.25L exemption)
• Sell-to-cover transactions: Tax withheld by foreign broker must be claimed as Foreign Tax Credit via Form 67

Schedule FA — Mandatory Annual Disclosure

Schedule FA — What to Disclose

• Country of the company
• Company name and description
• Date of acquisition
• Number of shares held
• Original cost of acquisition (in INR)
• FMV as on December 31 (in INR, converted at RBI rate)
• Income derived during the calendar year (dividends, capital gains)

FAST-DS 2026 — Limited Window for Past Non-Disclosure

ESOP perquisite income is technically salary — and employer TDS should cover it. But if TDS is not adequately deducted (employer miscalculation, or unlisted company delay in merchant banker valuation), the shortfall becomes your advance tax liability.

• If total tax liability after TDS exceeds ₹10,000 — advance tax installments are required
• Capital gains from ESOP sale arising after December 15 — include in March 15 installment, no prior quarterly obligation
• Capital gains arising before December 15 — include proportionately in the installment following the sale
• Missing advance tax → Section 234B and 234C interest at 1% per month

Which ITR Form

Schedule-wise Reporting

Documents to Keep

• ESOP grant letter (shows grant date, exercise price, vesting schedule)
• Exercise confirmation / allotment letter (shows allotment date — key for holding period)
• Merchant banker valuation report (unlisted only — 180-day validity)
• Form 16 / Form 130 and Form 12BA (perquisite detail)
• Broker demat statement (sale date, quantity, price)
• Foreign brokerage year-end statement (for Schedule FA)
• Form 67 and FIRC/foreign tax certificate (for FTC claims)

Mistake 1 — Using exercise price as capital gains cost of acquisition:
The most common and costly ESOP error. Your cost of acquisition is the FMV at exercise — not the exercise price. Using the exercise price taxes the perquisite gain twice. Section 49(2AA) explicitly sets FMV at exercise as the cost basis.

Mistake 2 — Assuming all DPIIT startups get TDS deferral:
Only DPIIT-recognised startups that also hold an IMB Certificate under Section 80-IAC qualify. A DPIIT certificate alone is not enough. Many startup employees assume deferral applies and are then surprised when their employer deducts TDS at exercise.

Mistake 3 — Missing Schedule FA for foreign ESOPs:
Even one foreign share held on December 31 requires Schedule FA disclosure. The calendar year basis (Jan–Dec) catches many people — those who joined an MNC and received RSUs mid-year often do not realise the December 31 cutoff applies to their first ITR. Penalty for non-disclosure: ₹10 lakh per year. FAST-DS 2026 is your last chance to regularise past omissions before December 31, 2026.

Mistake 4 — Not paying tax when leaving a deferral-eligible startup:
Cessation of employment immediately triggers payment of all deferred perquisite tax — regardless of whether shares are sold. Many startup employees leaving for new jobs face an unexpected large tax bill on their departure date. Plan ahead — either sell shares before leaving or maintain liquidity to pay on cessation date.
