Equity compensation is taxed twice, at two different times, at two different rates, on two different prices — and misunderstanding that sequence is how people end up paying real tax on paper wealth that later evaporated. The mechanics are the same whether your grant says ESOP, RSU or ESPP; only the trigger date moves.
Event one: the perquisite
The first taxable moment is when shares actually become yours — exercise for an ESOP, vesting for an RSU, purchase for an ESPP. The taxable amount is the discount you got: fair market value on that day minus what you paid (for an RSU, that is the entire FMV, since you paid nothing).
This discount is salary — a perquisite taxed at your slab rate plus cess, with TDS routed through payroll like any bonus. Three consequences people miss:
- It can push you into a higher slab in the vesting year, precisely because it stacks on top of normal salary.
- Tax is due on paper value. If you exercise and hold, you pay slab-rate tax on a gain you have not banked. A subsequent fall in the price does not refund it — the classic startup wound.
- Cash must come from somewhere. RSUs typically sell a slice to cover withholding; an exercised ESOP may not, leaving you to fund the TDS.
Employees of eligible DPIIT-registered startups can defer this perquisite tax — broadly until sale, leaving the company, or a statutory time limit, whichever comes first — a narrow but valuable carve-out worth checking with your CA.
Event two: capital gains
When you eventually sell, capital gains are computed from the FMV at event one, not from what you paid. The discount was already taxed as salary; taxing from your purchase price would tax it twice. Getting this cost basis wrong is the single most common error in self-filed returns with equity comp.
From there the ordinary share rules apply — the holding period starts at event one, and the rate depends on where the stock is listed. For Indian listed shares, STCG and LTCG at the special rates; for foreign-listed stock (the typical RSU from a US employer), the thresholds and rates differ, and the foreign holding also brings Schedule FA disclosure obligations. The ESOP tax calculator walks both events in sequence, and the RSU / ESPP calculator covers the vesting-driven variants. For how gains interact with your salary and the §87A rebate, see the salary + capital gains calculator.
The decision this forces
The tax code quietly frames a portfolio question: after vesting, holding the share is a fresh investment decision, not a continuation. You would rarely put several years of savings into one stock — your employer's, doubling your concentration with your paycheck — yet "doing nothing" after a vest is exactly that. Diversifying out is covered from the fund side in asset allocation and rebalancing.
⚠️ Perquisite valuation rules, startup deferral conditions and gains rates are statutory and change with Budgets and notifications. Verify current figures, and take an actual filing position from a professional — WealthTicker is not a SEBI-registered investment adviser and nothing here is tax advice.
Key takeaway
Equity comp is taxed at slab on the discount when it becomes yours, then as capital gains from that day's FMV when you sell. Budget cash for the first event, use FMV — not your purchase price — as the cost basis for the second, and treat every post-vest holding as a deliberate decision to concentrate in your employer's stock.

Decoding your CTC: why in-hand is so much less
Cost to company is what employing you costs, not what you are paid. The four layers inside a CTC, where EPF and gratuity actually go, and the basic-salary split that silently sets three benefits at once.
Old vs new tax regime: the choice that decides everything else
The new regime is the default and usually the winner — but not always. Where the break-even sits, why the §87A rebate never touches capital gains, and why the regime decides whether ELSS, HRA and 80D planning are worth anything at all.
Advance tax and TDS: how India collects before you file
TDS is a running prepayment, not the final bill, and advance tax fills the gap in four dated instalments. The 15/45/75/100 calendar, the cliff in the early triggers, and the presumptive shortcut that collapses it to one March payment.
Freelancing full-time: the 50% deal most professionals miss
Presumptive taxation lets a qualifying professional declare half of gross receipts as profit — no books, no audit, one advance-tax instalment. How the scheme works, and how to compare a salary and a freelance offer honestly.
How an EMI actually works (and the flat-rate trick)
Interest on the outstanding balance first, principal with the remainder — so early years barely repay anything. Why tenure sets total interest, why early prepayment punches above its weight, and why a flat rate is roughly double what it claims.
A surplus and a loan: prepay, refinance or invest?
Prepayment is a guaranteed, tax-free return equal to your loan rate — cut the tenure, not the EMI. When a balance transfer clears its fees, and when investing the surplus honestly beats both.
Rent vs buy: the honest math
Terminal net worth on two fully-specified paths, with the renter investing every rupee the buyer sinks. The two assumptions that decide the answer, and the tax change that flipped older calculators' verdicts.
The small savings family: PPF, SSY, NSC, KVP, SCSS and kin
One sovereign family, priced quarterly. Which schemes compound, which pay income, which are tax-exempt — and why the after-tax yield, not the poster rate, is the number to compare.
Insurance is not an investment: term plans and the LIC question
Bundled policies do both jobs badly. Sizing a term cover from needs rather than folklore, and evaluating an endowment you already own on forward numbers alone — surrender, paid-up or continue.
What trading actually costs: beyond zero brokerage
STT, exchange charges, GST, stamp duty and DP fees stack on every trade no broker can waive. The break-even move to know before a trade, the averaging-down trap, and what leverage really multiplies.
Running a small business by the numbers
Break-even and the margin of safety, margin versus markup, the cash conversion cycle, the DSCR a lender will compute anyway, and GST as an input-credit chain — the five checks that catch trouble early.
