ESOP vs RSU vs SAR: Which One Should Your Company Actually Offer?

Short answer: for most Indian private companies, a plain ESOP works best. RSUs make sense when you want simplicity and certainty for employees. SARs are rare in Indian startups — they solve a specific problem most companies don't have yet.

That probably saves you an hour of reading. But the details matter, because picking the wrong instrument creates tax headaches, accounting surprises, and the occasional boardroom argument. Let's walk through each one honestly.

What each instrument actually is

Strip away the jargon and you get three different promises.

An ESOP (Employee Stock Option Plan) gives employees the right to buy shares at a fixed price later. The price is set today. If the company grows, the employee buys low and owns something worth more. If it doesn't, they simply don't exercise. Under the Companies Act 2013, Section 62(1)(b) read with Rule 12 of the Companies (Share Capital and Debentures) Rules governs how private companies issue these.

An RSU (Restricted Stock Unit) gives employees actual shares (or the promise of them) once conditions are met — usually time-based vesting. No purchase price. No exercise decision. The shares just land in their account when they vest.

An SAR (Stock Appreciation Right) gives employees cash equal to the share price increase. No shares change hands. The employee benefits from growth without ever becoming a shareholder.

The ESOP: India's default, and usually the right call

Most Indian startups use ESOPs. There's a reason.

ESOPs align incentives beautifully. The employee only gains if the company grows — that's the whole point. And from the company's side, there's no cash outflow at grant. You issue options on paper; the real cost hits later, and mostly in accounting entries (Ind AS 102 requires you to expense the fair value over the vesting period — we'll come back to that).

Here's a scenario we see constantly. A Series A startup grants its head of engineering 10,000 options at an exercise price of ₹50 per share, vesting over four years with a one-year cliff. Three years later the company raises a Series B and the fair market value is ₹400. The engineer exercises, pays ₹5 lakh, and holds shares worth ₹40 lakh. That gap — ₹35 lakh — is the wealth-creation story that keeps people at startups.

The catch? Employees need cash to exercise. And they pay perquisite tax at exercise (more on that in our taxation post). For early employees at cash-strapped startups, coming up with the exercise money is a genuine problem. Some companies solve this with extended exercise windows or buyback programs. Most don't think about it until someone resigns and the problem lands on the table.

The RSU: Simpler for employees, heavier for the company

RSUs are the instrument of choice at large listed companies — think of the big tech firms. The appeal is obvious: the employee doesn't pay anything. Shares vest, shares arrive. Done.

For a private company, though, RSUs create complications. Every vested RSU is an immediate share issuance, which means immediate dilution and immediate tax for the employee (the full market value at vesting is perquisite income). There's no "I'll exercise later when I have cash" flexibility. The tax bill arrives whether the employee can sell or not.

We advised a growth-stage company that switched from ESOPs to RSUs because the founder thought "simpler is better." Within a year they switched back. Employees were getting tax bills on shares they couldn't sell — the company was still private, so there was no liquidity. One senior hire described it as "getting a bonus I had to pay tax on but couldn't spend." That's the RSU trap in a private company.

RSUs work well when there's liquidity — listed companies, or private companies with regular buybacks. Without an exit path, they can feel like a burden disguised as a benefit.

The SAR: Cash without shares

SARs are the least understood of the three, and in our experience, the least used by Indian startups.

The mechanics: the company promises to pay the employee the increase in share value over a set period. If the share goes from ₹100 to ₹250, the employee gets ₹150 per unit in cash. No shares issued. No dilution. No cap-table complexity.

Sounds clean. So why don't more companies use them?

Two reasons. First, SARs are a cash liability. When the payout comes due, the company writes a cheque. For a startup watching every rupee of burn, that's uncomfortable. ESOPs cost you dilution; SARs cost you cash. Most founders prefer the former.

Second, the accounting is unforgiving. Unlike ESOPs (which are equity-settled and expensed once at fair value), cash-settled SARs must be re-measured at every reporting date. If your valuation jumps, so does the liability on your books. We've seen CFOs blindsided by this during audit season.

SARs make sense in specific situations: a profitable private company that doesn't want to dilute, or a company rewarding employees in a division that won't get its own equity. But for a typical startup? They're a solution looking for a problem.

What about phantom stock and other variants?

You'll hear terms like "phantom stock" or "phantom options" thrown around. In the Indian context, these are usually just SARs by another name — cash-settled instruments that mirror share price movement without issuing shares. The legal and tax treatment follows the same logic.

One practical note: whatever you call it, if the instrument is cash-settled, budget for it. We've seen companies promise generous phantom plans during the good times and then struggle to pay out when valuations rose faster than revenue. Put a cap on the payout or a funding trigger in the scheme document. Your future self will thank you.

So which one should you pick?

Here's our honest framework after years of drafting these schemes:

Choose ESOPs if: you're a private startup or growth company, you want to conserve cash, and your employees understand (or can be taught) the exercise mechanics. This covers the large majority of our clients.

Choose RSUs if: you're listed, or you're private but run predictable buybacks, and you want employees to have zero-friction ownership. Simplicity has real value — just make sure there's liquidity behind it.

Choose SARs if: you specifically want to avoid dilution and you're comfortable with a cash liability. Be honest about whether you can actually pay when the time comes.

One more thing from the trenches: the instrument matters less than the communication. We've seen beautifully structured ESOP schemes fail because nobody explained them to employees, and simple schemes succeed because the founder sat down with every hire and walked through the math. Whatever you choose, explain it like you'd explain it to a smart friend who knows nothing about equity. That's your real test.

Your next step

Before you draft anything, answer three questions: Is there a realistic path to liquidity in the next 3–5 years? Can your employees afford to exercise? Can your company afford cash payouts? Your answers will point you to the right instrument nine times out of ten. Then get the scheme drafted under Section 62(1)(b) with proper board and shareholder approvals — the paperwork matters as much as the design.

Frequently asked questions

Can a private limited company in India issue RSUs? Yes. There is no legal bar on private companies granting RSUs. The framework is the same Section 62(1)(b) route used for ESOPs. The practical constraints are tax timing and liquidity, not legality.

Are SARs legal for Indian private companies? Yes. SARs are contractual arrangements and don't involve share issuance, so they sit outside the Section 62(1)(b) framework. However, cash-settled plans need careful accounting under Ind AS 102 and clear documentation of the payout formula.

Which is more tax-efficient for employees: ESOP or RSU? It depends on timing. ESOPs let employees choose when to trigger the perquisite tax (at exercise), which gives planning flexibility. RSUs trigger tax automatically at vesting. Neither is universally better — it depends on the company's liquidity and the employee's cash position.

Do we need shareholder approval for an ESOP scheme? Yes. Under Rule 12 of the Companies (Share Capital and Debentures) Rules, an ESOP scheme requires approval by special resolution of shareholders, along with prescribed disclosures. This applies to private companies as well as public ones.
