ESOP vs RSU: the tax difference Indian employees miss

You're at a startup. Your offer letter says "10,000 ESOPs at ₹10 exercise price." Your friend at an MNC gets "200 RSUs vesting over 4 years." Both of you think you have equity. Both of you are right — but the tax treatment is so different that the same nominal value can land very differently in your pocket.

Most employees understand, vaguely, that both instruments are taxed. What they miss is when, on what, and how the timing creates risks and opportunities that don't exist for the other instrument.

This piece covers all of it.

The fundamental difference: rights vs. shares

Before tax, understand what you actually have.

An RSU (Restricted Stock Unit) is a promise to give you a share on a future date — the vest date — at no cost to you. There is no exercise price. There is no decision to make. On vest day, shares appear in your brokerage account. You didn't buy them; you received them as compensation.

An ESOP (Employee Stock Option Plan) is a right to buy shares at a fixed price — the exercise price or strike price — set on the day of grant. You don't automatically get shares. You must decide to exercise the option, pay the exercise price, and receive shares in return. You can choose to exercise immediately after vesting, or wait years, or not exercise at all.

This distinction drives everything that follows.

How RSUs are taxed in India

Tax event 1: vest

When your RSUs vest, Indian tax law treats the value of shares received as a perquisite — a component of salary — under Section 17(2)(vi) of the Income Tax Act.

The perquisite value = FMV of shares on vest date − amount paid by employee.

Since you paid nothing for RSUs, the perquisite equals 100% of FMV on vest date.

This is taxed at your marginal slab rate. If you're in the 30% bracket (plus surcharge and cess), you're typically paying 34–42.7% on the vest value. Your employer computes this, deducts TDS, and reports it in your Form 16. You don't have to figure this out manually — but you should verify Form 16 reflects the correct FMV and exchange rate.

Tax event 2: sale

When you sell, the gain is a capital gain. The cost basis is the FMV on vest date (since you already paid tax on that amount as salary — the government can't tax it twice).

Capital gain = sale price − FMV on vest date

For foreign-listed shares (US companies, for most MNC employees):

• Hold more than 24 months → LTCG at 12.5% (no indexation benefit; treated as unlisted foreign equity under Section 112)
• Hold 24 months or less → STCG at your slab rate

The two-event summary for RSUs

You pay tax twice, but the amounts are predictable and the shares are liquid. There's no decision-making involved and no deferral available.

How ESOPs are taxed in India

This is where it gets complicated — because the tax treatment depends heavily on what kind of company gave you the options.

Scenario A: ESOPs in an Indian-listed company (e.g., Infosys, TCS, Wipro options)

At grant: no tax.

At vest: no tax. The options have vested, meaning you can exercise them, but you haven't yet. Shares haven't been transferred. No taxable event.

At exercise: this is the key moment. When you pay the exercise price and receive shares, a perquisite arises:

Perquisite = FMV on exercise date − exercise price

This is taxed as salary at your slab rate. TDS is deducted by the employer.

At sale: capital gain.

Capital gain = sale price − FMV on exercise date

Since the shares are listed on Indian exchanges:

• Hold more than 12 months → LTCG at 12.5% above ₹1.25 lakh annual threshold (Section 112A)
• Hold 12 months or less → STCG at 20% (Section 111A)

Note: Indian-listed shares use a 12-month holding period for LTCG, not 24 months.

Scenario B: ESOPs in an unlisted Indian startup

This is the most common situation for employees at funded startups in India, and it has the most moving parts.

At grant: no tax.

At vest: no tax.

At exercise: a perquisite arises — same calculation as above (FMV minus exercise price). But here's the critical difference:

Section 192(1C) deferral for DPIIT startups. If your employer is recognised by the Department for Promotion of Industry and Internal Trade (DPIIT), you are entitled to defer the TDS on this perquisite. The deferred TDS becomes due at the earliest of:

• 5 years from exercise date
• Date of sale of shares
• Date you leave the company

This deferral is massive. In a typical startup ESOP scenario, it means you don't pay any tax at exercise — all the tax is deferred until you sell or leave. You don't have to come up with tax money before the shares are liquid.

At sale: the taxable amount is split into two components:

1. Perquisite component (FMV at exercise − exercise price): taxed as salary in the year the deferral ends (typically the sale year).
2. Capital gains component (sale price − FMV at exercise): taxed as capital gains.

For unlisted shares:

• Hold more than 24 months from exercise → LTCG at 20% with indexation (Section 112)
• Hold 24 months or less → STCG at slab rate

Scenario C: ESOPs in a foreign-listed company (most MNC employees with options)

Less common than RSUs at MNCs, but some companies — especially older grants at companies like Cisco, IBM, or Accenture — issue options rather than RSUs.

At exercise: perquisite income = FMV on exercise date − exercise price (converted to INR at RBI reference rate on exercise date). Taxed as salary. Employer withholds TDS.

At sale: capital gains on foreign shares. Same treatment as RSUs — 24-month LTCG at 12.5%, STCG at slab rate.

No deferral available (the Section 192(1C) deferral is only for DPIIT-recognised Indian companies).

The differences that actually matter

1. Exercise timing creates a tax choice for ESOPs; RSUs give you no choice

With RSUs, you are taxed the moment shares vest. You cannot defer it. You cannot plan around it. The tax happens on a schedule determined by your vesting.

With ESOPs, you choose when to exercise. In a listed company, you might exercise in a year when your total income is lower (e.g., between jobs, or after a bonus year). In an unlisted startup with DPIIT deferral, you can exercise early — starting the capital gains clock — while deferring the perquisite tax until sale.

This optionality has real value. A ₹50 lakh perquisite taxed in a 42% marginal rate year hits very differently than the same perquisite spread over two lower-income years.

2. The spread risk — the problem ESOPs have that RSUs almost never do

This is the risk most startup employees discover too late.

Suppose you exercise ESOPs in your startup when the 409A/share valuation is ₹1,000 per share. Your exercise price is ₹10. You have a perquisite of ₹990 per share, taxed as salary. You pay (or defer) tax on ₹990.

Two years later, the company's fortunes decline. You sell at ₹500 per share. You have a capital loss of ₹500 per share (₹500 sale price − ₹1,000 FMV at exercise).

Here's the problem: you cannot offset a capital loss against salary income. The salary income (the ₹990 perquisite) was already taxed. The ₹500 capital loss can only be set off against capital gains — and if you don't have other capital gains in that year or the next 8 years, the loss is effectively worthless.

You paid tax on ₹990 and net received ₹490. That's a real loss of ₹500, but you also paid tax on ₹500 that effectively never materialised as wealth. The phantom income trap.

RSU holders face a much milder version of this: they're taxed on FMV at vest, the shares are immediately liquid in a listed company, and if they sell for less than FMV at vest, the capital loss is on the difference from a liquid, market-determined price. The mismatch is smaller and more predictable.

For illiquid startup shares, the spread risk is severe. Exercise with caution, especially if you're exercising at a high valuation without a clear near-term liquidity event.

3. DPIIT startup ESOP deferral is a major cashflow advantage

RSU holders at MNCs must pay TDS at vest — immediately, before selling a single share, typically through a sell-to-cover mechanism where some shares are sold to fund the tax. The cash goes to the government before you've decided anything.

Startup ESOP holders at DPIIT companies get to keep that cash (or rather, not pay it) until a liquidity event. That deferred tax is essentially an interest-free loan from the government until you sell. At 30%+ tax rates on crores of perquisite income, this can be significant.

The deferral does not reduce the tax owed — it only delays it. But timing matters a great deal.

4. Holding periods start at different points

This trips people up constantly.

RSUs: the capital gains holding period clock starts on the vest date — the date shares were transferred to your account.

ESOPs: the clock starts on the exercise date — the date you exercised the option and received shares. The grant date and vest date are both irrelevant.

If you exercised options in January 2024 and sold in February 2026, that's 25 months from exercise — LTCG. If you're calculating from the grant date (e.g., 2021) or vest date (e.g., 2023), you might get confused about whether you qualify for LTCG. Use exercise date only.

5. Schedule FA and foreign asset disclosure

If you have RSUs or ESOPs in a foreign company, you have foreign asset disclosure obligations in your Indian tax return.

Exercised ESOPs / vested RSUs held as shares: clearly must be disclosed in Schedule FA.

Unvested RSUs: you don't own shares yet, but you have a beneficial interest in shares that will vest. Most tax professionals recommend disclosure.

Unvested ESOPs: you have an option (a right, not yet exercised), in a foreign company. Whether this constitutes a "foreign asset" requiring disclosure is a genuine grey area in Indian tax law. The Black Money (Undisclosed Foreign Income and Assets) Act, 2015 has serious penalties for non-disclosure. The conservative position — and the one most advisors take — is to disclose. The risk of non-disclosure is not worth the paperwork saved.

Common mistakes to avoid

Assuming your MNC ESOP/RSU rules apply to your startup ESOP. They don't. The holding periods, rates, and deferral options are completely different.

Calculating capital gains from grant date or vest date instead of exercise date. For ESOPs, only the exercise date matters for the holding period.

Exercising startup ESOPs without thinking about the valuation. A high 409A valuation means a large perquisite, which means large tax (or large deferred tax). Exercise when the valuation is favourable, or when you have visibility into a liquidity event.

Not disclosing foreign equity in Schedule FA. The penalties under the Black Money Act are draconian. Always disclose.

Thinking capital losses from a startup write-down offset the salary income from the perquisite. They don't. Salary income and capital losses are in different buckets.
