Vest-Cycle Tax Strategy: Lot Selection and the 24-Month LTCG Clock
The 24-month clock is the single most important number in Indian RSU strategy — two days can move the same gain from 35.88% STCG to 12.5% LTCG. A deep look at lot selection, cross-FY harvesting, surcharge banding, and loss offsets.
The single most important number in Indian RSU strategy
Two days can change the tax on the same gain from 35.88% to 12.5%.
That is what the 24-month LTCG clock does, and it is the single most important number an Indian RSU holder needs to track. Most engineers we talk to know the rule exists. Almost none of them run a per-lot calendar. They watch the share price, the FX rate, the Form 16, the Schedule FA deadline — and they miss the one variable that, lot by lot, drives more of their final tax bill than any other decision they make.
The RSU Taxation pillar introduced the 24-month clock at a high level. This article lives inside it. We are going to look at lot selection, holding-period management, cross-FY harvesting, loss offsets, and surcharge-band positioning — the strategic layer that sits on top of the tax mechanics. Every figure is in rupees. Every example follows Priya, the Bengaluru-based Senior SWE at Google whose 1,000 GOOGL grant we have been tracking through the pillar series.
1. FIFO is not your friend — specific lot identification is
When you place a sell order at a US broker without specifying which lot you are selling, the broker defaults to FIFO — first-in, first-out. Your oldest lots get sold first. For most engineers, FIFO accidentally produces the right answer (oldest lots are LTCG-eligible). For anyone running active strategy, FIFO produces the wrong answer often enough to matter.
Indian tax law does not mandate FIFO. Specific lot identification — telling the broker exactly which tax lot to sell — is fully acceptable for computing Indian capital gains, provided the broker trade confirmation names the lot. The IT Department reads the lot identifier on the confirmation and applies the cost basis of that lot.
Where specific lot identification lives in each broker UI
Once you set the cost-basis method to specific lot identification, save the confirmation PDF for every sale. Indian audit defense requires the confirmation showing the lot identifier — not just “sold 100 GOOGL.” The broker statement at year-end may aggregate lots; the trade confirmation does not.
2. The month-23 mistake, in detail
We covered the month-23 mistake briefly in the RSU Taxation pillar. It is worth coming back to with full numbers because it is the most expensive operational mistake an Indian RSU holder makes.
Priya has 100 GOOGL shares from a vest dated October 15, 2023. Vest-day USD price was $138.50; RBI TT rate that day was ₹83.10. Her INR cost basis on this lot is locked at:
It is October 2025. GOOGL is trading at $185, INR is at ₹84.50. Her position is worth ₹15,63,250. The market has been jittery for two weeks and she wants to lock in the gain.
Two days of patience saves Priya ₹96,399 on this single lot, on essentially the same price. The market does not move materially in 48 hours, but the tax classification does.
The variant of this mistake we see most often is the panic sell five trading days before LTCG. Engineers see a 4–6% market dip in October, watch a few headlines, and place a market-sell order on lots that vested in November or December the prior year. The dip turns a sale that would have been LTCG-eligible in two weeks into an STCG event. The behavioral pattern is consistent enough that we have an internal name for it on the Rovia engineering team: “October dip, January regret.”
3. The 24-month-1-day rule — why strict reading matters
Section 2(42A) of the Income Tax Act defines a long-term capital asset as one held for more than 24 months for unlisted/foreign equity. The word is “more than,” not “at least.” Strict interpretation: the holding period must strictly exceed 24 months.
Two practical readings:
- Sale on the exact 24-month anniversary (e.g., vest Oct 15, 2023; sale Oct 15, 2025) is ambiguous. Some Assessing Officers count it as LTCG; some count it as STCG. The Tribunal jurisprudence leans toward STCG on the anniversary itself, but it is not a defended-everywhere position.
- Sale on 24 months + 1 day (e.g., vest Oct 15, 2023; sale Oct 16, 2025) is unambiguously LTCG.
Industry practice for material positions: wait 25 months, not 24 months + 1 day. The extra month is cheap insurance against an Assessing Officer reading the anniversary aggressively. On a ₹10L gain, the LTCG-vs-STCG differential is ~₹2.34L — worth paying a 30-day market-risk premium to remove all ambiguity.
4. Cross-FY harvesting — splitting gains across surcharge bands
India's financial year ends March 31. Capital gains are taxed in the FY in which the trade occurs. A sale on March 30 falls in FY 2025-26; a sale on April 2 falls in FY 2026-27. The choice of FY changes which annual-income bucket the gain stacks into — and that determines your surcharge band.
The surcharge bands as of FY 2025-26
Surcharge applies on top of base tax once total income crosses certain thresholds. Under the new tax regime — which most senior ICs default into — the bands are:
The new regime caps the top surcharge at 25%, removing the 37% band that exists under the old regime. For capital-gains income specifically, the surcharge on LTCG is also capped at 15% even when other income would attract 25%. The effective LTCG figures above reflect this cap plus 4% cess.
Worked example — Priya splits a ₹50L gain
Priya is sitting on a block of GOOGL she has been planning to liquidate to fund a Bengaluru property purchase. Her base salary and current vests put her at ₹95L of non-RSU annual income — already in the 10% surcharge band, but well below the ₹1Cr line.
She has a ₹50L LTCG sitting in her position. If she takes it all in FY 2025-26, her total income for the year becomes ₹95L base + ₹50L gain = ₹1.45Cr — pushing her over the ₹1Cr surcharge threshold into the 15% band. The LTCG portion gets the 15% surcharge cap (~15.0% effective on the gain). The salary portion crosses into ~35.9% effective.
Alternatively, she takes the ₹50L gain as ₹25L in FY 2025-26 (sale on March 30, 2026) and ₹25L in FY 2026-27 (sale on April 2, 2026). Now each year her total income is ₹95L + ₹25L = ₹1.20Cr — still in the 15% band, so the LTCG surcharge stays the same. The salary side, however, stays below the ₹2Cr line in both years, avoiding the 25% surcharge stack on her base.
The bigger split benefit arrives when income is closer to the ₹50L threshold. Consider a younger engineer at ₹40L base with a ₹40L gain available — the choice of taking the full gain in one FY (total ₹80L, 10% surcharge band) versus splitting (₹20L + ₹20L, each year ~₹60L, still 10% band) is neutral for LTCG. But adding deductions and other small income items, a real-world split can keep one of the two years below ₹50L entirely, saving ~3% of effective rate on every rupee of LTCG that year.
Numbers above are illustrative — they assume standard deductions and no other adjustments. Real-world savings on a ₹50L split are typically ₹2–5L when the split crosses a surcharge band on either the base or the gain side, especially for engineers near the ₹50L and ₹2Cr lines.
5. Loss harvesting in foreign equity
Indian tax law allows capital losses to offset capital gains under specific rules. For Indian RSU holders, the relevant section is 74(1):
- Short-Term Capital Loss (STCL) can offset both STCG and LTCG of the same FY. Whatever does not get used in the current year carries forward for 8 assessment years, set off against future STCG or LTCG.
- Long-Term Capital Loss (LTCL) can offset only LTCG — never STCG. Same 8-year carry-forward.
- Capital losses cannot offset salary or perquisite income. So the perquisite tax on your RSU vest is untouchable by capital losses — only the capital-gain portion of your tax bill is in scope.
For RSU holders at multi-stock companies (or anyone who has accumulated multiple grants), the STCL/STCG offset is the most useful planning lever — STCL is the more flexible loss class.
Worked example — Priya offsets a NFLX loss against GOOGL gains
Priya joined Google in 2022, but before that she had a one-year stint at Netflix, leaving with 100 vested NFLX shares from her final tranche. Her NFLX cost basis from that vest was ₹19,00,000 (vest at ~$230, RBI rate ~₹82.60).
It is February 2026. NFLX is trading at $160, INR at ₹85.20. Her NFLX position is worth ₹13,63,200. She has a ₹5,36,800 unrealized loss. The lot is 17 months old — still STCG territory if sold.
Separately, she has a GOOGL lot she sold last quarter at a ₹5L STCG (also short-term). Without action, that ₹5L STCG attracts 35.88% tax = ₹1,79,400.
She sells the NFLX position on February 20, 2026 — crystallizing the ₹5,36,800 STCL. The mechanics:
The ₹36,800 of unused STCL carries forward 8 years. Crucially, Priya can use that future STCL against either STCG or LTCG — STCL is the more flexible class.
A note on the “wash sale” question: India does not have a US-style 30-day wash-sale rule for capital losses. You can sell a NFLX position to crystallize a loss and rebuy NFLX the same day or the next day, and the loss is still recognized. However, audit defense for an obviously round-tripped position is weaker; the prudent approach is at least a few days, ideally a different security, between the loss-realizing sale and any rebuy.
6. Surcharge banding as a multi-year game
Senior ICs at Google, Meta, Microsoft, and Amazon often hover right around the ₹1Cr to ₹2Cr line — base salary, refresh grants, and accumulated vest stacks regularly push total income into the 15% band, and large sales can push it into the 25% band.
The strategic move is to treat surcharge band positioning as a multi-year game, not a per-vest decision. Three patterns work consistently:
- Accelerate sales in a low-base year. If you take a sabbatical, between jobs, or have an unpaid leave year, that is the cheapest time to liquidate a large RSU stack. Total income for the year drops below ₹50L, surcharge drops to zero, LTCG effective rate sits at ~13.0% all-in instead of ~15.0%.
- Defer sales in a high-base year. If you closed a record bonus or an unusual one-off (e.g., a vested signing payout) and you can hold the RSU position into the following FY, do so. Same gain, different bucket year, materially lower effective rate.
- Use the L1/L2 transition year. Engineers moving between L5 and L6 (or L6 and L7) often see refresh stacking that puts them temporarily into the ₹2Cr+ bracket for one year. A planned hold-through-the-transition can keep that year clean of large discretionary sales.
7. Putting it together — a yearly cadence
A complete vest-cycle tax strategy operates on three time scales simultaneously:
- Per-lot (weekly review). Track 24-month anniversaries. Flag lots crossing into LTCG in the next 30 days. Flag lots in month 22–24 as “do not sell” until the clock matures.
- Per-FY (quarterly review). Estimate the year's total income — base + RSU perquisites already realized + capital gains realized + remaining vests through March. Project surcharge band. Identify whether a planned sale should be cross-FY split.
- Multi-year (annual review). Map your next 24–36 months of vests against your career trajectory (promotions, sabbaticals, switches). Identify low-base years for accelerated liquidation; identify high-base years for deferral.
Most engineers operate on time scale 1 only — react to the vest, maybe glance at the calendar before selling. The lift from running all three scales together is what makes the difference between a 14% effective rate and a 16.5% effective rate on the same gain stack. Across a senior-IC career with ₹3–5Cr of total RSU income, that is ₹7–15L of unforced overpayment.
8. What Rovia does
The vest-cycle planning layer is what Rovia was built to replace. Spreadsheets cannot do this; they go stale within a week of any vest or sale. The platform handles each of the levers above directly:
- Per-lot 24-month countdown. Every lot from every broker (Schwab, Morgan Stanley, E*TRADE, Fidelity) shows its current holding-month count and its LTCG-eligible date. The lot inventory view sorts by “days until LTCG” so the most strategically sensitive lots surface to the top.
- “Do not sell before [date]” alerts. Every lot generates two alerts: a month-23 warning (you are approaching the STCG cliff — pause discretionary sales) and a month-24+1 confirmation (this lot is LTCG-eligible from this date). Both surface to email and the dashboard.
- Surcharge-band sale recommender. Given your year-to-date income and projected remaining vests, the platform estimates which surcharge band you will land in and recommends whether to take a planned sale in the current FY or defer to next FY. Recommendations are quantified in rupees of expected tax savings.
- Loss-harvest opportunity scanner. The platform continuously evaluates your full inventory for loss positions that, if realized, would offset realized or projected gains in the same FY. If you have a NFLX paper loss and an unhedged GOOGL STCG, the scanner surfaces the trade and the tax saving.
- Specific lot identification guidance. When you initiate a sale, the platform proposes which specific lot to sell given your strategic goals — LTCG harvesting, loss harvesting, or surcharge-band positioning — and produces the broker-specific instructions to execute.
The per-company broker-switch walkthroughs cover the operational layer: Google, Meta, Microsoft, Amazon, Apple, Netflix.
Frequently asked questions
Is the 24-month LTCG clock inclusive or exclusive of the vest date?
Strictly, the holding period must exceed 24 months — the sale must occur after 24 months have elapsed since the vest date, not on the anniversary itself. The safe industry practice is to wait until day 24 months + 1, and for material positions to allow a full extra month of buffer. Day-of-anniversary sales are defensible but invite scrutiny; nobody wants to argue a ₹2L tax differential in front of an Assessing Officer.
If I tell my US broker to sell a specific lot, does the Indian IT Department honor that?
Yes, provided the broker confirmation shows the specific tax lot identifier. India does not mandate FIFO; specific lot identification is fully acceptable for Indian capital-gains computation. Keep the broker trade confirmation that names the lot — it is your audit defense.
Can I offset US RSU short-term losses against my Indian salary income?
No. Capital losses — short-term or long-term — cannot offset salary income in India. STCL can offset STCG and LTCG; LTCL can offset only LTCG. Both can be carried forward for 8 assessment years, but only against capital gains of the same character class.
Does the cross-FY split work if I sell on March 31?
The cut-off is end-of-day March 31 in your broker time zone. Indian capital gains attach to the trade date, not the settlement date. So a trade executed on March 31 (US market hours) falls in the current FY; a trade on April 1 falls in the next FY. Many engineers lose the split by mistiming a US-market trade — March 31 IST evening is often April 1 in some interpretations, so leaving a 24-48 hour buffer is safer.
What happens to the LTCG clock if I ACATS-transfer my shares to a new broker?
An in-kind ACATS transfer preserves your original acquisition (vest) date — the 24-month clock continues uninterrupted. A sell-and-rebuy at the new broker resets the clock, with the new purchase establishing a fresh 24-month window. The Broker Transfer pillar covers the mechanics.
I have a paper loss on NFLX that I have not sold. Can I claim it now?
No. Capital losses in India crystallize only on sale. An unrealized paper loss is not deductible. To use it, you must execute a sale before March 31 of the relevant FY, which crystallizes the STCL or LTCL — then it offsets eligible gains in that FY or carries forward 8 years.
