What is an RSU? Restricted Stock Units — complete 2026 guide for Indian employees

A Restricted Stock Unit, almost universally abbreviated to RSU, is an unfunded contractual promise by an employer to deliver one share of company stock to an employee on a future date, conditional on continued service and on any performance conditions specified in the grant agreement. Until that future date — the vesting date — the employee has no legal title, no voting rights and no entitlement to dividends. On vesting, the share is transferred into the employee's brokerage account and the fair market value on that date becomes taxable compensation: a perquisite under Section 17(2)(vi) of the Income-tax Act, 1961 in the hands of an Indian-resident employee and ordinary income subject to FICA and federal withholding in the hands of a US-resident employee. This guide is the canonical 2026 reference for the RSU as a financial and tax instrument as held by Indian residents working for US-headquartered multinationals.

Restricted Stock Units originated in the United States in the mid-1990s as a deferred-compensation instrument used sparingly at the executive level and became the dominant form of broad-based equity compensation at US-listed technology employers after Sarbanes-Oxley and FAS 123R required options to be expensed at fair value on the income statement. Microsoft was the first large US technology company to switch fully from options to RSUs, in July 2003; Google, Amazon, Apple, Meta and the rest of the index followed within a decade. For an Indian resident in 2026, the working assumption is that any equity grant from a US-listed multinational employer is an RSU unless the offer letter says otherwise.

The action-oriented playbook covering the full grant-to-sale lifecycle, withholding mechanics and reinvestment decisions sits in the companion piece The complete RSU guide for Indians at US multinationals. This page is the definitional canonical — what an RSU is, how it differs from adjacent instruments, and where it sits in Indian and US tax law.

Definition and legal nature

An RSU is three things at once. It is a deferred compensation contract: the employer agrees to pay future compensation in shares rather than cash. It is an unfunded promise: no shares are set aside in escrow and the employee has no recourse against any specific pool of assets if the employer becomes insolvent before vest. And it is a contingent right: the promise to deliver lapses if the service condition is not met, which makes the right non-vested for accounting and tax purposes until the contingency is resolved.

The "unit" element distinguishes the instrument from restricted stock proper, where actual shares are issued at grant and are subject to a substantial risk of forfeiture. A unit is the right to one share, settled in the future. Settlement is almost always in shares for US public-company plans; cash-settled RSUs exist but are rare.

Under Indian law, the RSU itself is not a capital asset until vest, because no asset has been transferred — Section 2(14) defines a capital asset as property held by an assessee, and a contingent contractual right is not property. Under US law, Section 83 of the Internal Revenue Code and Treasury Regulation 1.83-3 carve out unfunded, unsecured promises to transfer property in the future from the operation of Section 83 entirely. The consequence is that the Section 83(b) early-taxation election available on restricted stock proper is not available on RSUs in either jurisdiction.

How RSUs work — grant, vesting, settlement

The RSU lifecycle has three legal events — grant, vesting and settlement — corresponding to the issuance of the promise, the satisfaction of the service condition and the delivery of the share. In modern US plans, vesting and settlement happen simultaneously, so most people treat them as one event called "vest day".

Grant is the day the board, or the compensation committee acting under delegation, approves a written grant agreement specifying the number of units, the vesting schedule, any performance conditions, the treatment on termination and the governing plan document. The employee typically receives electronic notice through the stock plan administrator — Fidelity NetBenefits, E*TRADE Equity Edge, Morgan Stanley StockPlan Connect or Shareworks, Charles Schwab Equity Award Center, or Carta for newer private companies — and accepts. Grant is a zero-tax event in both India and the United States.

Vesting is the day the service condition is satisfied for a particular tranche. For a four-year monthly vest with a one-year cliff, the first vesting event is the cliff date on which twenty-five percent vests; thereafter, vesting events occur monthly or quarterly until exhausted at year four. The fair market value used for tax purposes is the closing price on the vesting date, or the value defined by the plan document.

Settlement is the day the share is transferred into the brokerage account. In modern plans this occurs on the vest date or within a small number of trading days thereafter, within the safe harbour of the US Section 409A short-term deferral rule. From settlement, the share is a registered equity holding with full voting and dividend rights and full alienability subject only to insider-trading windows and any post-vest holding period imposed by the employer.

History — RSUs versus stock options

Through the 1980s and 1990s, the standard equity instrument at US public companies was the non-qualified stock option, NSO, with the incentive stock option, ISO, reserved for tax-favoured grants up to a statutory limit. Options aligned employee and shareholder interests asymmetrically: employees participated in upside through the spread between strike and market price but bore no downside because they could simply decline to exercise. The dot-com bust demonstrated the asymmetry brutally — millions of options issued at strike prices in 1999 and early 2000 became worthless as the Nasdaq fell three-quarters by late 2002.

Two regulatory developments closed the chapter. Sarbanes-Oxley, 2002 strengthened internal controls over financial reporting. FAS 123R, effective for fiscal years beginning after June 2005, required all share-based payments to be expensed at fair value. Once options carried the same accounting cost as RSUs, the case for options collapsed for broad-based use, because RSUs delivered guaranteed compensation while options could deliver zero. By the mid-2010s, RSUs were the universal default at US-listed technology employers for engineers, product managers and most non-executive staff. Stock options survived in two niches: pre-IPO private companies, where strike-priced options remain meaningful because the share carries a low Section 409A valuation, and executive grants tied to stretch performance targets.

For the comparative tax and economic treatment of stock options in the hands of Indian residents, the stock options ISO NSO India tax guide is the companion reference.

Vesting schedules at major US technology employers

The four-year vest with a one-year cliff remains the modal schedule, but several large employers deviate materially. The deviations matter economically because they change the effective annual compensation in early service years. The schedules below are taken from publicly disclosed plan documents and offer-letter samples shared by Indian employees; refresher grants, sign-on stubs and executive overrides can differ.

Employer	Initial grant schedule	Cliff	Cadence after cliff
Microsoft	25 / 25 / 25 / 25 over 4 years	None at hire	Quarterly from grant date
Google (Alphabet)	33 / 33 / 22 / 12 front-loaded over 4 years	1 year	Monthly thereafter
Meta (Facebook)	25 / 25 / 25 / 25 over 4 years	1 year	Quarterly thereafter
Apple	25 / 25 / 25 / 25 over 4 years	1 year then April / October	Semi-annual thereafter
Amazon	5 / 15 / 40 / 40 back-loaded over 4 years	1 year	Semi-annual thereafter
Nvidia	25 / 25 / 25 / 25 over 4 years	1 year	Quarterly thereafter
Adobe	25 / 25 / 25 / 25 over 4 years	1 year	Quarterly thereafter
Oracle	25 / 25 / 25 / 25 over 4 years	1 year	Annual or quarterly by band
Salesforce	25 / 25 / 25 / 25 over 4 years	1 year	Quarterly thereafter
Atlassian	25 / 25 / 25 / 25 over 4 years	1 year	Quarterly thereafter

Amazon's back-loaded schedule is the outlier and is supplemented by a large signing bonus in years one and two, paid in cash, that substitutes for the small RSU vests in those years. Google's historical front-loaded schedule has, by 2026, been partially revised to a flatter 25-25-25-25 grid for new hires in some bands, though the older grid still applies to many existing employees. RSU vesting: the real tax math for Indian residents walks the rupee-denominated tax payable on a representative vest under each pattern.

Indian tax treatment — perquisite at vest

Indian tax treatment operates in two stages governed by two different sections. The first is the perquisite charge at vest. The second is the capital gain charge at sale. Conflating them is the single most common source of error.

At vest, the fair market value of the vested shares, converted to Indian rupees, is a perquisite under Section 17(2)(vi) of the Income-tax Act, inserted with effect from 1 April 2010 by the Finance Act, 2009 and covering specified securities and sweat equity shares allotted or transferred by the employer free of cost or at concessional rate. RSUs are specified securities for this purpose. Rule 3(8) of the Income-tax Rules prescribes the valuation: for listed shares, the average of opening and closing price on the vest date; for unlisted shares, a merchant-banker valuation no more than 180 days old. For US-listed shares, listed treatment applies and the NYSE or Nasdaq opening-closing average governs.

Rupee conversion uses Rule 115 of the Income-tax Rules — the SBI telegraphic transfer buying rate on the last day of the month immediately preceding the perquisite event. The employer is required by Section 192 to withhold tax at the employee's marginal rate including surcharge and cess in the month of vest. For an employee at the thirty-percent slab with a fifteen-percent surcharge applicable above two crore, the effective rate is approximately 35.88 percent. Withholding is operationally executed through sell-to-cover.

The perquisite amount, once added to gross salary in Form 16, flows into the Salaries head in the return. There is no separate schedule; the amount sits inside the salary line. A common compliance gap is failure of the US parent to communicate the vest to the Indian payroll entity in time, leaving the perquisite off Form 16 — the employee must then add it manually or request a revised Form 16 before filing.

Indian tax treatment — capital gain at sale

On sale, the cost basis is the rupee FMV at vest — the same figure that already bore perquisite tax. Sale consideration is the rupee proceeds, converted under Rule 115 using the rate of the last day of the month preceding the sale month. The difference is the capital gain.

The character of the gain depends on holding period. For shares not listed on any recognised stock exchange in India — every US-listed company in the hands of an Indian resident — the threshold for long-term treatment is 24 months under Section 2(42A), as rationalised by the Finance (No. 2) Act, 2024. Over 24 months yields long-term capital gain at a flat 12.5 percent under Section 112(1)(a) without indexation. Twenty-four months or less yields short-term capital gain at slab rates under Section 45 read with Section 111. The Rs 1.25 lakh exemption under Section 112A does not apply, because Section 112A is reserved for STT-paid Indian listed equity.

Worked example — a representative Indian RSU vest

Consider Priya, a senior software engineer at the Indian subsidiary of a US-listed semiconductor company. On 15 February 2026, a tranche of 100 RSUs vests under her four-year quarterly schedule. The closing price on the vest date is USD 140. The State Bank of India telegraphic transfer buying rate on 31 January 2026 — the last day of the month preceding the vest — is INR 87 per USD. Priya is in the thirty-percent marginal slab with a ten-percent surcharge applicable.

Line item	Computation	Amount
Gross vest value, USD	100 shares times USD 140	USD 14,000
Gross vest value, INR	USD 14,000 times INR 87	INR 12,18,000
Perquisite added to salary	Same	INR 12,18,000
Base tax at 30 percent	30 percent of INR 12,18,000	INR 3,65,400
Surcharge at 10 percent	10 percent of INR 3,65,400	INR 36,540
Subtotal	Sum	INR 4,01,940
Cess at 4 percent	4 percent of INR 4,01,940	INR 16,078
Total perquisite tax	Sum	INR 4,18,018
Effective tax rate at vest	Total tax over gross	34.32 percent
Shares sold to cover at USD 140 and INR 87	INR 4,18,018 divided by INR 12,180 per share	34.32 shares, rounded to 35
Net shares delivered	100 minus 35	65 shares

Priya now holds 65 shares with a per-share cost basis of INR 12,180. She holds for 26 months and sells on 20 April 2028 at USD 200. The SBI TT buying rate for 31 March 2028 is, hypothetically, INR 92 per USD. Sale proceeds are 65 times USD 200 times INR 92, equal to INR 11,96,000. Cost basis is 65 times INR 12,180, equal to INR 7,91,700. Long-term capital gain is INR 4,04,300. Tax under Section 112 at 12.5 percent plus surcharge plus cess is approximately INR 56,602.

Total tax across vest and sale is INR 4,74,620. The post-tax outcome is materially better than if Priya had sold immediately at vest, because the vest-to-sale appreciation was taxed at 12.5 percent under Section 112 rather than at her marginal slab. The strategic implications are in Should you sell RSUs at vest or hold?.

Sell-to-cover mechanics

Sell-to-cover is the default tax-withholding mechanism used by every major US stock plan administrator — Fidelity NetBenefits, E*TRADE, Morgan Stanley StockPlan Connect or Shareworks, Charles Schwab, Carta. On the vest date, the administrator computes the gross share count, applies the withholding rate specified by the Indian employer payroll team to the gross perquisite, divides the rupee tax by the per-share market price translated to rupees, rounds up to the next whole share, and places a market order. The sale executes on the open market alongside hundreds of other employees vesting on the same date.

The rupee proceeds are remitted through the US parent's intercompany channel to the Indian subsidiary's TDS payroll line. The Indian entity deposits the tax under the employee's PAN and reports it in Form 16. The employee sees only the net share count in the brokerage account. Misalignment between the withheld rate and the actual marginal rate produces a self-assessment top-up or refund at year-end, walked through in RSU vesting tax math.

The Sell-to-cover simulator models the share count net of withholding at user-specified prices, exchange rates and marginal-rate assumptions.

Multi-jurisdictional attribution when vesting spans countries

The standard case is an Indian-resident employee who worked entirely in India for the full vesting period. The non-standard case is the employee whose vesting period straddles a US and an India posting — typically an engineer who started at the US headquarters, accrued part of a vesting tranche while resident in the United States, transferred to the India entity, and is an Indian resident on the vest date.

Article 16 of the India-US Double Taxation Avoidance Agreement, in force from 18 December 1990 with effect from 1 January 1991 for the United States, allocates the right to tax employment income to the country in which services were performed. Indian tax authorities have consistently applied a working-days apportionment for vesting compensation that accrues over a service period: the US-sourced fraction bears US supplemental wage withholding plus state tax where applicable, and the India-sourced fraction bears Indian perquisite tax.

For the US-sourced fraction, India — as residence state on the vest date — gives a foreign tax credit under Article 25, claimed by filing Form 67 before the due date under Section 139(1). The credit is capped at the lower of US tax actually paid and the Indian tax that would have applied. Procedural mechanics are in Form 67 foreign tax credit India and, for the AY 2026-27 transition, in Form 67 and Form 44 transition. Relocation casework, including the proportional reset of the cost basis on tax residency change, is in Employer transfer US to India relocation tax reset.

Schedule FA reporting

Every vested RSU share held in a foreign brokerage account during the relevant calendar accounting period must be disclosed in Schedule FA of the Indian return — ITR-2 for salaried individuals without business income. The Schedule FA accounting period is the calendar year preceding the assessment year, irrespective of the fiscal year. For AY 2026-27 it is calendar 2025.

Disclosure is in Table A3, "Foreign equity and debt interest held at any time during the calendar year": country, entity name, address, ZIP, nature of interest, date of acquisition, initial cost in INR at acquisition-date rate, peak value during the year, closing value at 31 December, and dividends and capital gains separately. Unvested RSUs are not reportable. Detailed mechanics are in Schedule FA for AY 2026-27 step-by-step.

Schedule FA failure exposes the taxpayer to the Black Money (Undisclosed Foreign Income and Assets) and Imposition of Tax Act, 2015 penalty regime, substantially harsher than ordinary Income-tax Act penalties and applicable even where the underlying income has been correctly offered to tax.

DTAA treatment and Form 67 reclaim

The DTAA assigns capital gains on the alienation of US-listed shares to the residence state under Article 13, so an Indian resident selling vested RSU shares pays no US tax on the capital gain. The US has no withholding on share sale proceeds for non-resident aliens holding US-listed equity. The full gain is taxed in India under Section 112 or at slab rates depending on holding period.

The DTAA bites only on the perquisite at vest, and only when some portion of the vesting period was worked in the United States. For that portion, the US imposes federal income tax through supplemental wage withholding — twenty-two percent on wages up to USD 1 million and thirty-seven percent above — plus FICA, plus state tax where applicable. The Indian return gives a foreign tax credit for the US tax paid, claimed in Form 67. A worked example for a 60-40 US-India split is in Form 67 foreign tax credit India.

Dividends on the held shares are taxed differently. The US withholds at the 25 percent DTAA rate on dividends paid to Indian residents, evidenced by Form 1042-S. The dividend is offered to tax in India under "Income from other sources" and a foreign tax credit is claimed through Form 67. How US stocks are taxed in India covers dividends end-to-end.

RSU versus ESPP versus stock options

The three instruments most often confused with each other in Indian RSU conversations are the RSU itself, the Employee Stock Purchase Plan (ESPP) and the stock option. The economic, legal and tax profiles diverge substantially.

Attribute	RSU	ESPP	Stock option
Underlying right	Free share at vest	Right to buy at discount	Right to buy at strike
Cost to employee	Zero	Discounted purchase price	Strike price on exercise
Vesting	Service-based	Offering period accrual	Service-based
Taxable event in India	Vest date	Purchase date	Exercise date
Perquisite measure	FMV at vest	Discount over FMV at purchase	Spread of FMV over strike
Downside protection	Always positive value at vest	Capped lookback floor	Worthless if below strike
Typical Indian employer	Every US listed multinational	Most US listed multinationals	Pre-IPO and executive
US accounting cost	Fair value of share	Fair value of discount and lookback	Fair value of option

Section 83(b) and why it does not apply to RSUs

Section 83(b) of the US Internal Revenue Code lets the holder of restricted property — actual shares subject to a substantial risk of forfeiture — elect to recognise the value as ordinary income at transfer, before the restriction lapses, in exchange for treating subsequent appreciation as capital gain. The election must be filed within thirty days. It is a powerful tool for founder restricted stock and for early-stage employee restricted stock awards with a low Section 409A valuation at grant.

RSUs are not eligible. Section 83 operates only on property that has actually been transferred; an RSU is a contractual promise, not a current transfer. Treasury Regulation 1.83-3(e) confirms that an unfunded, unsecured promise is not property within the meaning of Section 83. Vesting is the taxable event in both the United States and India. Indian residents holding RSUs do not have an 83(b) decision to make.

Where an Indian resident receives a restricted stock award rather than an RSU — rare, but possible in pre-IPO contexts — the 83(b) election may be available on the US side. The Indian perquisite still arises when the restriction lapses, because Section 17(2)(vi) keys to allotment or transfer "free of cost or at concessional rate" and the substantial risk of forfeiture defers transfer. This combination warrants individualised advice and is beyond the scope of this reference.

Special cases

Leaving before vest. Unvested RSUs are forfeited the moment employment ends, unless the grant or a separation agreement provides for acceleration. Vested shares already delivered belong to the employee and are unaffected. Some plans accelerate on death, disability, retirement after a defined age, or change of control. Full casework is in RSUs when changing jobs or laid off.

Accelerated vesting on acquisition. Most US employer equity plans contain a double-trigger acceleration clause: vesting accelerates only if a change-of-control event occurs and the employee is terminated without cause or resigns for good reason within a defined window. Single-trigger acceleration is rare outside executive grants. Where double-trigger fires, the entire unvested grant vests on the trigger date and is sold for cash consideration in the merger.

Secondary market post-IPO. For RSUs that vested before the company went public, the underlying shares typically sit subject to a 180-day post-IPO lockup. Vesting has already occurred and tax has been paid at the IPO-implied price; the lockup affects only liquidity. Sale post-lockup follows ordinary capital gain treatment from the vest-date cost basis.

Pre-IPO RSUs and the illiquidity problem. For employees at private US companies whose RSUs are double-trigger — vesting requires both the service condition and a liquidity event such as IPO or acquisition — Indian treatment is materially different. No perquisite arises until both triggers are satisfied. When the liquidity event occurs, the entire accumulated grant vests in one event and produces a large perquisite charge at the IPO-implied price, often without immediate ability to sell because of lockups. Covered in Pre-IPO RSUs — the tax-liquidity problem.

Common mistakes by Indian RSU holders

Six mistakes recur. First, treating grant as a taxable event — it is not, only vesting is. Second, using the grant-date price as cost basis on sale, which overstates the capital gain by the entire vest-to-sale appreciation that already bore perquisite tax; the correct cost basis is the vest-date FMV. Third, omitting vested shares from Schedule FA on the assumption that perquisite tax has been paid — Schedule FA is an asset disclosure independent of the income tax position, and Black Money Act exposure follows omission regardless. Fourth, failing to claim foreign tax credit for US tax withheld on vests that include US-sourced service days. Fifth, holding the entire post-vest portfolio as company stock, producing single-stock concentration risk that is irrational once the employee already bears career risk to the same employer — addressed in Should you sell RSUs at vest or hold? and tooled in the RSU concentration tracker. Sixth, trusting that the Indian employer's Form 16 captures the full perquisite — for subsidiaries whose US parent does not synchronise vest data, the employee must reconcile to the brokerage statement and add any under-reported portion. The tracking discipline that makes this tractable is in Cost basis tracking for RSUs spreadsheet.

The RSU is, in the end, an unfunded promise dressed in compensation language. Its legal nature is a contingent contractual right, its economic nature is deferred salary, and its tax nature is salary at vest and capital gain at sale. For Indian residents, the doctrine begins at Section 17(2)(vi), passes through Rule 115 for the rupee conversion, lands at Section 112 for the sale, and is reconciled to the United States through Articles 16 and 25 of the DTAA. Every other RSU article on this site is a specialisation of one of those lines.
