RSUs vs Stock Options vs SARs vs Phantom Stock: A Valuer’s Comparison

RESEARCH BRIEF & REGULATORY FOUNDATIONS

Regulatory Governance: ESOPs are governed under Section 62(1)(b) of the Companies Act, 2013 and SEBI (SBEB) Regulations 2021. Cash-settled synthetic equity operates under the Indian Contract Act, 1872.

Tax & Valuation Triggers: ESOP perquisites are taxed at exercise based on Merchant Banker valuation (Rule 3(8) of IT Rules). RSUs trigger salary tax at vesting on full FMV. Synthetic equity (Phantom/Cash SARs) is taxed upon disbursement as regular compensation and is fully tax-deductible under Section 37(1).

Strategic Imperative: Selecting the right equity vehicle requires balancing dilution control, executive tax friction, balance sheet liquidity, and cap table governance.

RSUs vs. Stock Options vs. SARs vs. Phantom Stock: A Valuer’s Comparison

Designing an equity incentive scheme is one of the most critical structural decisions a founder, CFO, or board will make. Get it right, and you align key talent with long-term enterprise value. Get it wrong, and you end up with an overcrowded cap table, disgruntled executives facing unexpected tax liabilities, or severe cash flow bottlenecks during liquidity events.

When founders ask our team which equity instrument to issue, they often treat Stock Options (ESOPs), Restricted Stock Units (RSUs), Stock Appreciation Rights (SARs), and Phantom Stock as minor variations of the same concept. From a valuation, tax, and corporate governance perspective, they are entirely different financial instruments.

Here is a structured comparison of these four incentive vehicles from the desk of a valuation and corporate finance advisor.

1.  Employee Stock Option Plans (ESOPs): The Early-Stage Standard

Structural Overview

An ESOP grants an employee the right—but not the obligation—to purchase company shares at a predetermined exercise price (strike price) after completing a designated vesting period. Under Indian company law, ESOPs are governed by Section 62(1)(b) of the Companies Act, 2013 and Rule 12 of the Companies (Share Capital and Debentures) Rules, 2014. For listed companies, SEBI (Share Based Employee Benefits and Sweat Equity) Regulations, 2021 apply.

[Grant Date] ——> [Vesting Date] ——> [Exercise Date] ——> [Share Sale]

(Vesting Period)                    (Perquisite Tax)         (Capital Gains)

The Valuer’s Perspective

For early-stage startups where current share value is low, ESOPs remain the default mechanism. The exercise price is typically set near nominal face value or the Fair Market Value (FMV) at grant.

• Tax Event 1 (Exercise): The difference between the FMV on the exercise date and the exercise price is treated as a salary perquisite under Section 17(2)(vi) of the Income Tax The employer must deduct TDS under Section 192.
• Tax Event 2 (Sale): The difference between the final sale price and the exercise-date FMV is taxed as Capital Gains (Short-Term or Long-Term based on holding period).

Perquisite Value = (FMV on Exercise Date − Exercise Price) × Number of Shares

For unlisted companies, determining FMV on the exercise date requires a mandatory valuation report from a SEBI-registered Category-I Merchant Banker under Rule 3(8) of the Income Tax Rules.

1.Strategic Risk

The primary drawback of ESOPs in unlisted growth-stage companies is the dry-income trap. If an employee exercises options in a high-valuation startup without a simultaneous buyback or secondary sale, they owe immediate cash perquisite tax on paper gains. While Section 192(1C) permits a 5-year deferral of ESOP perquisite tax for “eligible startups,” this benefit is strictly limited to companies holding an Inter-Ministerial Board (IMB) certificate under Section 80-IAC—a hurdle that fewer than 10% of DPIIT-recognized startups actually satisfy.

Below is a practical numeric example that illustrates the “dry-income trap” faced by employees of unlisted startups.

Example: Dry-Income Trap in an Unlisted Startup ESOP

Background

Mr. A is an employee of ABC Technologies Private Limited, an unlisted startup.

On 1 April 2023, he was granted 10,000 ESOPs with an exercise price of ₹20 per share.

On 1 July 2026, after vesting, he exercises all the options.

A Registered Valuer determines the Fair Market Value (FMV) of the shares on the exercise date to be ₹300 per share.

However, since the company is unlisted, there is no IPO, buyback, or secondary sale, and therefore Mr. A cannot sell the shares immediately.

Step 1: Exercise Cost

Number of ESOPs = 10,000

Exercise Price = ₹20 per share

Exercise Cost =

= 10,000 × ₹20

= ₹2,00,000

Mr. A pays ₹2 lakh to acquire the shares.

Step 2: Perquisite Value under Section 17(2)(vi)

FMV on Exercise Date = ₹300

Exercise Price = ₹20

Perquisite per share

= ₹300 − ₹20

= ₹280

Total Perquisite

= 10,000 × ₹280

= ₹28,00,000

This ₹28 lakh is treated as salary income.

Step 3: Income Tax Liability

Assume Mr. A falls in the 30% tax bracket.

Perquisite Tax

= ₹28,00,000 × 30%

= ₹8,40,000

Health & Education Cess @4%

= ₹33,600

Total Tax Payable

= ₹8,73,600

Cash Flow Position

2.  Restricted Stock Units (RSUs): The Late-Stage & MNC Preference

Structural Overview

An RSU is a commitment by the company to deliver full shares to the employee upon satisfying vesting conditions, with zero exercise price.

The Valuer’s Perspective

Unlike ESOPs, RSUs carry no exercise step. Upon vesting, shares are allotted directly to the employee.

• Tax Event: Because the strike price is ₹0, the entire Fair Market Value of the shares on the vesting date is classified as a salary perquisite.
• Capital Gains: The cost basis for subsequent capital gains is set at the vesting-date FMV.

Perquisite Value = FMV on Vesting Date × Number of Shares

For public MNCs or listed Indian firms, RSUs are highly effective because employees can automatically execute a “sell-to-cover” transaction on the open market to meet their tax obligations. In private, unlisted companies, issuing RSUs creates substantial balance sheet and personal tax friction. Employees receive illiquid stock while incurring an immediate salary tax obligation at their full slab rate. Consequently, experienced valuers generally advise unlisted startups against RSUs unless paired with liquidity mechanisms.

3.  Stock Appreciation Rights (SARs): Hybrid Flexibility

Structural Overview

Stock Appreciation Rights grant employees a payout equal to the appreciation in company share value over a designated base price during the vesting window. SARs can be equity-settled (issuing shares worth the gain) or cash-settled (paying cash equal to the gain).

SAR Value Created = Current Share Valuation − Base Price

The Valuer’s Perspective

Equity-Settled SARs: Function similarly to ESOPs but significantly reduce cap table dilution. Instead of issuing 10,000 shares at a ₹100 strike price when current FMV is ₹500, the company issues only ₹400,000 worth of net value—translating to 8000 net shares rather than 10,000 gross shares.

Cash-Settled SARs: Do not involve share issuance or equity allotment. The entire appreciation payout is treated as performance-linked cash compensation, taxed directly as salary income.

From an accounting perspective under Ind AS 102 (Share-based Payment), equity-settled SARs are measured at fair value on grant date and equity-classified, whereas cash-settled SARs must be re-measured at fair value at every reporting date as a liability—introducing earnings volatility.

4.  Phantom Stock: Synthetic Equity Without Cap Table Dilution

Structural Overview

Phantom Stock gives selected executives the financial benefits of equity ownership without issuing actual legal shares, voting rights, or governance titles. The company creates “units” that mirror the movement of real share value. Upon a trigger event (e.g., exit, tenure completion, or valuation benchmark), the unit value is paid out in cash.

Phantom Unit Payout = Units Held × (Exit / Trigger Valuation per Share)

The Valuer’s Perspective

Phantom Stock is a contractual cash bonus plan linked to valuation metrics.

• No Cap Table Impact: Zero dilution, no entry on the register of members, and no minority shareholder protection claims.
• Tax Mechanics: The cash settlement is taxed as regular salary income at the employee’s applicable slab rate when disbursed. Capital gains tax rules do not apply.
• Corporate Tax Advantage: Unlike real equity issuance, cash payments under Phantom Stock plans are fully deductible operational expenses for the company under Section 37(1) of the Income Tax Act, lowering the corporate tax burden.

Strategic Risk

The biggest danger with Phantom Stock is unfunded cash liability risk. If enterprise valuation scales 10x over four years, the business faces a massive, non-dilutive cash obligation on its balance sheet. Without cash reserves or an exit liquidity event, this obligation can strain corporate solvency.

Valuer’s Comparative Decision Matrix

Practical Decision Guidance for Founders and CFOs

1. Early-Stage Seed to Series A Startups: Stick to standard ESOPs. Your valuation is low, the exercise price is minimal, and cash conservation is ESOP pools (typically 10%–15%) remain an investor prerequisite during fundraising rounds.
2. Growth-Stage Unlisted Companies (Series B through Pre-IPO): Consider Equity-Settled SARs to conserve equity pool capacity, or structure ESOPs with an extended post-termination exercise window to reduce cash strain on departing
3. Promoter-Held Businesses, SMEs, and Family Enterprises: Use Phantom Stock. Promoters rarely want external family/individual holdings on their register of members. Phantom Stock aligns executive incentives with enterprise growth while preserving absolute equity ownership and voting
4. Public Companies and Late-Stage Unlisted Unicorns: Deploy RSUs for senior leadership. High valuation certainty paired with deep liquidity makes RSUs an effective retention

 Final Takeaway

There is no universally “superior” incentive model—only structures that match your growth stage, balance sheet, and cap table priorities. If your primary goal is cash conservation and investor alignment, real equity instruments (ESOPs) are effective. If your priority is retaining voting control, avoiding equity dilution, and rewarding senior leadership, synthetic equity (Phantom Stock or Cash SARs) provides a cleaner structure.
