Use this RSU tax calculator to work out how much tax you owe on your Restricted Stock Units (RSUs) the moment they vest. This RSU tax calculator applies the current salary-perquisite rules under the Income-tax Act, 2025, so tech employees, startup staff, and NRIs holding foreign stock can get an instant, accurate number instead of guessing.

What Is RSU Tax Calculator?

An RSU tax calculator estimates the income tax you owe when your Restricted Stock Units vest and convert into actual shares. It's built for salaried tech employees at Indian offices of foreign companies, startup employees receiving equity compensation, and NRIs and cross-border employees who hold RSUs from a US or other foreign listed employer. Instead of manually working out slab-wise tax on a lump-sum perquisite, you enter your vesting details once and read off the number.

RSU Tax Calculator Formula (as per Section 17, Income-tax Act, 2025)

RSUs are taxed at two separate points — vesting and sale. This calculator focuses on the vesting-stage tax, which is the one every RSU holder faces first.

Step 1 — Perquisite value:

Perquisite Value = Number of RSUs Vested × Fair Market Value (FMV) per share on vesting date

Step 2 — Tax on perquisite:

Total Taxable Income = Other Annual Income + Perquisite Value
Tax = Slab-wise tax on Total Taxable Income − Slab-wise tax on Other Annual Income (before RSU)

The fair market value of the vested shares is treated as a perquisite and added to your salary income under Section 17 of the Income-tax Act, 2025, which took effect from 1 April 2026 and governs Tax Year 2026-27. This replaces the old Section 17(2)(vi) of the Income-tax Act, 1961. Valuation follows Rule 15 of the Income-tax Rules, 2026 [VERIFY — rule number not independently confirmed on an official government page]. If your RSUs are from a foreign company, the FMV must be converted to INR using the SBI TT Buying Rate on the vesting date.

An RSU carries no purchase price, so the entire FMV is taxable — unlike ESOPs, where only the gain over the exercise price is taxed.

How This Calculator Works

1. Enter the number of RSUs that vested on a given date.
2. Enter the FMV per share on that vesting date, converted to INR if it's a foreign stock.
3. Add your other annual income (salary, freelance income, etc.) so the calculator can apply the correct tax slab — RSU perquisite is taxed at your marginal rate, not a flat rate.
4. Choose your tax regime — new or old. If you're unsure which one is better for you, run the old vs new tax regime calculator first.
5. The calculator computes your perquisite value, applies the applicable slab rates and standard deduction, and shows the tax attributable to your RSU vesting along with your total tax liability.

Step-by-Step Example Calculation

Rohit works at the India office of a US-listed tech company. On his vesting date, 50 RSUs vest when the stock trades at $150 per share.

1. Convert to INR: Using the SBI TTBR on the vesting date (₹86/USD), FMV per share = ₹12,900.
2. Perquisite value: 50 shares × ₹12,900 = ₹6,45,000.
3. Other annual income: Rohit's salary (excluding RSU) is ₹18,00,000.
4. Total taxable income: ₹18,00,000 + ₹6,45,000 = ₹24,45,000.
5. Tax without RSU (new regime, after ₹75,000 standard deduction): taxable income ₹17,25,000 → slab tax ₹1,45,000, plus 4% cess = ₹1,50,800.
6. Tax with RSU (taxable income ₹23,70,000): slab tax ₹2,92,500, plus 4% cess = ₹3,04,200.
7. Tax attributable to RSU: ₹3,04,200 − ₹1,50,800 = ₹1,53,400 — this is what Rohit's RSU vesting actually cost him in tax.

This incremental method matters because RSU income stacks on top of your salary and can push part of it into a higher slab.

Who Should Use RSU Tax Calculator

• Tech and IT employees at Indian subsidiaries of US-listed companies receiving RSU grants as part of CTC.
• Startup employees holding equity compensation structured as RSUs.
• NRIs and cross-border employees who vested RSUs while working in India and now need to estimate Indian tax exposure.
• Freelancers and consultants with equity comp who also draw other income and need a combined slab-wise estimate.
• CAs and finance professionals who need a quick perquisite-tax cross-check before filing a client's ITR-2 or ITR-3.

Latest Rules You Should Know (2026)

• The Income-tax Act, 2025 came into force on 1 April 2026, replacing the 1961 Act for Tax Year 2026-27. Perquisite taxation, earlier under Section 17(2)(vi), now falls under Section 17 of the new Act.
• Budget 2026 made no change to income tax slab rates. The new regime slabs remain: nil up to ₹4 lakh, then 5%, 10%, 15%, 20%, 25%, and 30% in ₹4-lakh bands up to ₹24 lakh.
• The Section 87A rebate makes tax nil for taxable income up to ₹12 lakh under the new regime (₹12.75 lakh including the ₹75,000 standard deduction). Just above that line, marginal relief caps your tax at the amount your income exceeds ₹12 lakh by — so crossing the threshold by ₹1 doesn't suddenly cost you ₹60,000. Use the Section 87A marginal relief calculator to check this precisely for your own numbers.
• On the sale side, foreign or unlisted-in-India RSU shares count as unlisted for capital gains: holding them past 24 months qualifies for long-term treatment at a flat 12.5% (no indexation) — check the exact figure on the long-term capital gains tax calculator; selling within 24 months means short-term gains taxed at your slab rate. [VERIFY — capital gains rate not independently re-confirmed on an official government page this session]
• If you hold foreign RSU shares, disclose them in Schedule FA of your ITR every year you hold them — even if you haven't sold a single share. Read more in the foreign assets disclosure guide. [VERIFY — reconfirm against incometax.gov.in ITR utility/instructions before publishing]

Common Mistakes People Make

• Using the grant-date value instead of the vesting-date FMV. Tax is triggered at vesting, not when the RSU was granted.
• Forgetting the currency conversion. Foreign RSU FMV must be converted using the SBI TTBR on the exact vesting date, not an average or a later date.
• Ignoring other income while estimating tax. RSU perquisite stacks on your salary — computing tax on the RSU value alone at a flat rate understates your real liability.
• Assuming the sale is a second, separate tax hit on the full amount. Only the appreciation above the vesting-date FMV is taxed again at sale; the FMV itself was already taxed as salary.
• Not checking Form 12BA and Form 16 Part B. The perquisite value your employer reports should match what you compute — mismatches are a common audit flag.
• Skipping Schedule FA disclosure for foreign RSU holdings, even in years with no sale.

FAQs

Is RSU vesting taxable in India even if I don't sell the shares? 

Yes. Tax is triggered the moment RSUs vest, based on the fair market value on that date — regardless of whether you sell immediately or continue holding the shares.

What tax rate applies to RSU perquisite income? 

There's no separate flat rate. The perquisite value is added to your salary and taxed at your normal slab rate, same as any other salary income for that year.

Do I pay tax twice — once at vesting and again when I sell? 

No. At vesting, the FMV is taxed as salary. At sale, only the gain above that already-taxed FMV is taxed as capital gains — the same rupee isn't taxed twice.

How is the FMV of foreign RSUs converted to INR? 

Using the SBI TT Buying Rate (TTBR) applicable on the vesting date, as prescribed under the Income-tax Rules for perquisite valuation.

Which ITR form should I file if I hold foreign RSUs? 

Resident taxpayers holding foreign RSUs typically file ITR-2 or ITR-3, and must additionally complete Schedule FA to disclose the foreign holding.

Is surcharge applicable on RSU perquisite income above ₹50 lakh? 

Yes, but this calculator doesn't include it — it computes slab tax and cess only. If your total income exceeds ₹50 lakh, add surcharge separately or check with a CA.
