Short answer: no, you are not paying tax twice on the same money. But yes, a single batch of RSUs creates two separate taxable events, and most people only plan for one of them.
The first tax event happens the day your RSUs vest, before you have sold a single share. The fair market value (FMV) of the vested shares is treated as a perquisite and added to your salary income for the year, and your employer withholds tax on it exactly like it withholds tax on your paycheck.
The second tax event happens later, whenever you sell, and it's a completely separate calculation, capital gains tax on whatever the shares have gained (or lost) since the day they vested.
If you've been assuming 'I only owe tax when I sell,' that assumption is wrong for the vesting side, and it can leave you underpaying tax through the year without realizing it.

The vesting-day tax: a perquisite, taxed as salary
On the date your RSUs vest, the FMV of the vested shares is treated as a perquisite, which forms part of your salary income for that year. This happens whether or not you sell the shares that day, next month, or five years later.
This perquisite is taxed under Section 17(2)(vi) of the Income Tax Act, and the cost of acquisition it fixes (more on that below) is the same FMV figure that goes into that computation. Because it's salary income, your employer is required to deduct Tax Deducted at Source (TDS) on it under Section 192, the same section that governs TDS on your regular pay.
For the INR conversion, the applicable exchange rate is generally the SBI TT Buying Rate (TTBR) on the vesting date itself, since RSU vesting almost always triggers immediate TDS withholding, which shifts the applicable conversion date to the date tax was required to be deducted.
The sale-day tax: capital gains, on the gain since vesting only
Whenever you eventually sell those shares, whether that's the same afternoon or three years later, you trigger a second, unrelated tax event: capital gains tax.
Two mechanics matter here, and they're commonly gotten wrong:
- Holding period and rate: RSU shares sold within 24 months of the vest date are classified as short-term capital gains (STCG) and taxed at your income slab rate, not a flat rate. Shares held more than 24 months from vesting are long-term capital gains (LTCG), taxed at 12.5%, without indexation. Foreign capital gains also attract surcharge and cess on top of that base rate.
- No ₹1.25 lakh exemption: the ₹1.25 lakh LTCG exemption under Section 112A applies only to Indian listed equities, not to foreign stocks like US-listed RSU shares. Don't apply it here.
An example spanning both stages
Example. Suppose you're a senior engineer at Qualcomm, and 200 of your RSUs vest on a single date. The FMV that day is $168 per share, and the SBI TTBR on the vesting date is ₹86.20/USD. For simplicity, this example assumes your total income for the year stays under the ₹50 lakh surcharge threshold, so only the 30% slab rate and the 4% health and education cess apply.
Stage 1: vesting.
| Item | Amount |
|---|---|
| Shares vesting | 200 |
| FMV per share | $168 |
| SBI TTBR (vesting date) | ₹86.20 |
| Perquisite value (200 × $168 × ₹86.20) | ₹28,96,320 |
| Tax at 30% slab | ₹8,68,896 |
| Health and education cess (4%) | ₹34,756 |
| Total TDS withheld at vesting (Section 192) | ₹9,03,652 |
The result: about ₹9.04 lakh is withheld from your pay the month these RSUs vest, and this amount now sits in your Form 16 as salary income, before you've decided whether to sell a single share.
Stage 2: sale. Ten months later, still within the 24-month STCG window, you sell all 200 shares at $185 per share, when the exchange rate happens to be ₹87.50/USD.
| Item | Amount |
|---|---|
| Sale price per share | $185 |
| Exchange rate on sale date | ₹87.50 |
| Sale value (200 × $185 × ₹87.50) | ₹32,37,500 |
| Cost of acquisition (Section 49(2AA), = vest-day perquisite value) | ₹28,96,320 |
| Capital gain | ₹3,41,180 |
| Holding period | 10 months → STCG, taxed at slab rate |
| Tax at 30% slab | ₹1,02,354 |
| Cess (4%) | ₹4,094 |
| Total tax on sale | ₹1,06,448 |
The result: a second, separate tax bill of roughly ₹1.06 lakh, calculated only on the ₹3.41 lakh gained since vesting, not on the ₹32.37 lakh sale value.
Add the two stages together and you paid roughly ₹10.10 lakh in tax across the life of this one batch of shares, about ₹9.04 lakh as salary tax at vesting and about ₹1.06 lakh as capital gains tax at sale. That's not the same rupee taxed twice. It's two different tax bases (FMV at vesting, then gain since vesting) taxed once each, at different times, under different sections.
Why this means you may owe advance tax, not just TDS
The vesting-side tax in the example above is handled for you: your employer withholds it as TDS under Section 192 and reports it in Form 16. If your payroll team knows about the vest and adjusts your withholding for the rest of the financial year, that ₹9.04 lakh is largely covered before you ever think about it.
The sale-side tax is a different story. When you sell foreign RSU shares through a broker outside India, there is no Indian TDS deducted on the capital gain at the point of sale. That ₹1,06,448 liability from the example is entirely yours to account for, and it doesn't wait for your employer or your broker.
This is where advance tax comes in. You are legally required to pay advance tax if your estimated total tax liability for the financial year, after deducting TDS already paid, is ₹10,000 or more. A capital gain like the one above, on its own, clears that bar easily. India's income tax runs on a 'pay as you earn' principle: instead of settling the full year's tax as one lump sum when you file your return, the tax department expects it paid in installments as the income arises, and this applies to salaried individuals with additional income sources, not only freelancers or business owners.
Advance tax is paid online through the Income Tax Department's e-filing portal using Challan 280, selecting '100 - Advance Tax' as the payment type. The cumulative due dates are (per the Income Tax Department's advance tax payment schedule): at least 15% of the year's estimated tax by 15 June, 45% by 15 September, 75% by 15 December, and 100% by 15 March. Miss the installment for the quarter your sale falls in, and the whole point of pay-as-you-earn is defeated.
If you have RSUs vesting on a regular cadence (many employers vest quarterly), you don't have one vesting event and one sale event a year, you can have several of each. Each vest creates its own perquisite and TDS entry, and each sale creates its own, separate capital gains calculation against that vest's specific cost of acquisition. Treat 'how much tax do I actually owe this quarter' as a running number, not a once-a-year question, especially in a year where you're also selling shares from earlier vests, earning dividend income, or have other income outside your salary.
