Founder Personal Tax Planning under the Income-tax Act, 2025 — ESOP, LTCG, 80-IAC and Section 54F

Last Updated: 15 April 2026  |  Applicable From: Tax Year 2026-27 (1 April 2026 onwards)  |  Reference: Income-tax Act, 2025 (30 of 2025), as amended by Finance Act, 2026

The Income-tax Act, 2025 received Presidential assent on 21 August 2025 and commenced on 1 April 2026. For India’s startup founders — whether bootstrapped, angel-funded or late-stage — the transition to the new Act is an opportunity to rebuild personal tax planning from first principles. This guide is written for working founders, co-founders facing liquidity events, and pre-IPO promoters whose equity is about to crystallise into cash. It walks through the two-stage ESOP taxation framework, the holding period and rate rules for long-term capital gains, the DPIIT-recognised 80-IAC startup tax holiday and ESOP deferral, the Section 54F reinvestment route for sale proceeds, the regime choice between the new default and the old opt-out, sweat equity and bonus equity treatment, secondary sale valuation, and the interaction of shareholders’-agreement rights (ROFR, co-sale, drag-along) with tax planning.

Definition — Founder (for tax purposes): A promoter or key employee of a startup who holds equity in the entity, typically acquired through a founder share subscription at inception, a sweat equity allotment, an ESOP exercise, or a combination. Under the Income-tax Act, 2025, founders are taxed the same as any other resident individual — there is no separate “founder” tax status — but the intersection of the salary head (for ESOPs and sweat equity) and capital gains head (for equity sales) creates unique planning opportunities.

Definition — Eligible Startup (Section 80-IAC equivalent): An entity incorporated as a private limited company, LLP or registered partnership, recognised as an eligible startup by the Department for Promotion of Industry and Internal Trade (DPIIT), with a turnover not exceeding ₹100 crore in any tax year since incorporation, and engaged in innovation, development or improvement of products or services. Eligibility triggers access to the 3-year tax holiday and the ESOP deferral facility.

Featured Answer — What are the key founder tax planning levers under the Income-tax Act, 2025?

A founder should think about tax planning across seven levers under the 2025 Act: (1) ESOP exercise timing — exercise in a tax year when salary income is low or the company valuation is low, to minimise the perquisite; (2) holding period discipline — hold unlisted shares for more than 24 months to access the 12.5% LTCG rate; (3) DPIIT recognition and 80-IAC — apply for DPIIT recognition and then for the 80-IAC tax holiday to preserve company-level cash flow; (4) ESOP perquisite deferral — for founder-employees of eligible startups, use the 60-month deferral to delay the TDS impact of the perquisite; (5) Section 54F reinvestment — route net sale consideration into a residential house to claim full or proportional exemption; (6) regime choice — run the new-regime-vs-old-regime comparison annually, especially in ESOP exercise years; (7) secondary sale valuation — ensure sale consideration meets or exceeds FMV to avoid the Section 50CA deemed addition. A founder who ignores any one of these levers typically leaves 15-25% of total exit value on the table.

ESOP — The Two-Stage Taxation Framework

The Income-tax Act, 2025 preserves the two-stage ESOP taxation framework from the repealed Act:

Stage 1 — Perquisite at exercise. When the founder-employee exercises the option and is allotted shares, the difference between the fair market value of the shares on the exercise date and the exercise price paid is treated as a perquisite under the salary head (successor to old Section 17(2)(vi)). This amount is added to the founder’s total income and taxed at the applicable slab rate. The company deducts TDS under the salary withholding provision of the 2025 Act (successor to old Section 192).

Worked Example — ESOP exercise: A founder-employee is granted 20,000 options at an exercise price of ₹10 per share. After 4 years of vesting, she exercises when the FMV (as determined by a SEBI-registered merchant banker under the prescribed rules) is ₹450 per share. Perquisite value = (₹450 – ₹10) × 20,000 = ₹88,00,000. This ₹88 lakh is added to her salary income for tax year 2026-27. Assuming she is in the 30% slab with surcharge and cess, the tax on this perquisite alone is approximately ₹30-32 lakh. The company deducts TDS on this perquisite from her regular salary, which creates an immediate cash-flow stress — hence the importance of the ESOP deferral facility for eligible startups.

Stage 2 — Capital gains at sale. When the founder subsequently sells the shares, the difference between the sale price and the FMV on the exercise date (which becomes her cost of acquisition for capital gains) is taxed as capital gains. The holding period for determining whether the gain is long-term or short-term begins from the date of exercise (when the shares are allotted), not the date of grant or vesting. For unlisted shares, LTCG applies after 24 months — for listed shares (post-IPO), after 12 months.

FMV Determination for Unlisted Shares

For unlisted company shares (the reality for most ESOPs before IPO), the FMV on the exercise date must be determined in accordance with the prescribed valuation rules — successor to old Rule 3(8) of the Income-tax Rules. The accepted methods are:

The choice of method can significantly affect the perquisite quantum. Founders should ensure the valuation is conducted by a qualified professional, is documented, and is defensible in the event of assessment scrutiny.

ESOP Deferral for Founder-Employees of Eligible Startups

The 2025 Act preserves the ESOP perquisite tax deferral facility for founder-employees of DPIIT-recognised eligible startups (successor to the deferral introduced by Finance Act, 2020 under old Section 191(2) and 192(1C)). Under this provision, the employer’s TDS obligation on the ESOP perquisite is deferred to the earliest of the following events:

The deferral is a TDS deferral — not a permanent tax exemption. The tax liability still arises, but the timing is delayed, aligning the tax with a future liquidity event. This is a major cash-flow relief for founder-employees who would otherwise need to pay tax on an illiquid notional gain. To access the deferral:

Section 80-IAC Startup Tax Holiday

The Section 80-IAC equivalent of the Income-tax Act, 2025 provides a 100% tax holiday on profits for 3 consecutive tax years out of the first 10 tax years from the date of incorporation of the eligible startup. The key features:

Capital Gains on Founder Shares — LTCG and STCG

Type of Share Holding Period for LTCG LTCG Rate STCG Rate
Unlisted shares (pre-IPO founder equity) > 24 months 12.5% flat (no indexation) Slab rates
Listed equity (post-IPO, through stock exchange with STT) > 12 months 12.5% (exemption ₹1,25,000 per tax year) 20%
Listed equity (off-market, no STT) > 12 months 12.5% flat Slab rates

Key points for founders:

Section 54F — Reinvestment Exemption

The Section 54F equivalent of the Income-tax Act, 2025 is the single most powerful reinvestment shelter available to a founder exiting their equity. It allows a founder to claim exemption on LTCG from the sale of any long-term capital asset (other than a residential house) — crucially, this includes founder shares — if the net sale consideration is reinvested in the purchase or construction of a residential house in India within the prescribed timelines.

Key conditions

Proportional exemption formula

Where only part of the net consideration is reinvested, the exemption is proportional:

Exempt LTCG = LTCG × (amount invested in new house / net sale consideration)

Worked Example — Section 54F: A founder sells founder shares for a net consideration of ₹8 crore, with LTCG of ₹7 crore (held for 6 years, cost was ₹1 crore). Without any planning, tax at 12.5% on ₹7 crore = ₹87.5 lakh (plus surcharge and cess). The founder buys a residential house in Chennai for ₹5 crore within the 2-year window. Proportional exemption = ₹7 crore × (₹5 crore / ₹8 crore) = ₹4.375 crore. Taxable LTCG = ₹7 crore – ₹4.375 crore = ₹2.625 crore. Tax = ₹32.8 lakh + surcharge/cess. Saving through Section 54F = ₹54.7 lakh. Where the founder reinvests the full ₹8 crore into a house, the LTCG is fully exempt.

The ₹10 crore cap on Section 54F exemption (introduced by Finance Act, 2023 and carried forward into the 2025 Act) limits the exemption to LTCG on net consideration up to ₹10 crore. For exits above this level, founders should plan for partial exemption and possibly time sales across tax years to utilise the cap more than once.

Regime Choice — New vs Old under the 2025 Act

The Income-tax Act, 2025 retains the dual-regime structure carried forward from the 1961 Act. The new regime is the default; the old regime is available on opt-out.

Feature New Regime (Default) Old Regime (Opt-out)
Slab rates Nil up to ₹4L; graduated to 30% above ₹24L Nil up to ₹2.5L; 30% above ₹10L
Standard deduction (salaried) ₹75,000 ₹50,000
Rebate (nil tax up to) ₹12,00,000 income (₹12.75L for salaried) ₹5,00,000 income
Section 80C / life insurance / PPF / ELSS Not available ₹1,50,000
Section 80D (health insurance) Not available ₹25,000 / ₹50,000 (seniors)
HRA exemption Not available Available
Home loan interest deduction Not available ₹2,00,000 (self-occupied)
Section 80G (donations) Not available 50% or 100% available
Capital gains head Same rates apply Same rates apply

Regime choice for founders — rule of thumb. For most salaried founders in tax year 2026-27, the new regime is more favourable because (a) it preserves a generous standard deduction, (b) the rebate shields income up to ₹12 lakh entirely, (c) most founders do not have significant Section 80C / 80D / HRA / home-loan claims until late career, and (d) the surcharge rates are favourable. The old regime can still win for founders with (a) an active home loan with ₹2 lakh interest, (b) significant life insurance premium, (c) full HRA claim in a Tier-1 city, and (d) meaningful Section 80G donations. In an ESOP exercise year, when total salary spikes, the comparison should be re-run from scratch — the marginal benefit of old-regime deductions becomes larger at higher income levels.

Sweat Equity, Bonus Shares and Secondary Sales

Sweat equity

Sweat equity issued to founders is taxed in the same two-stage framework as ESOPs under the 2025 Act. At allotment, the difference between the FMV and the amount paid by the founder (often nil) is a perquisite. At sale, the difference between sale price and FMV at allotment is capital gains. The deferral facility for DPIIT-eligible startups extends to sweat equity allotments where the founder is an employee.

Bonus shares

Bonus shares received as an existing shareholder are not treated as income at allotment — the 2025 Act carries forward the zero-cost basis rule. The cost of acquisition of bonus shares is NIL. On subsequent sale, the entire sale consideration is treated as capital gain. The holding period for bonus shares begins from the date of allotment of the bonus shares, not the date of the original shares. This is a critical point for founders considering a sale shortly after a bonus issue — a sale within 24 months (unlisted) or 12 months (listed) of the bonus allotment falls on the STCG side.

Secondary sales and the Section 50CA deemed FMV

In a secondary sale — where a founder sells existing shares to a new investor without fresh issue — the sale is taxed under capital gains at the applicable rate. The 2025 Act carries forward the Section 50CA deeming provision: where unlisted shares are sold below FMV, the FMV as per prescribed rules is deemed to be the sale consideration. Valuation discipline is therefore essential. Founders should obtain a fresh valuation report at the time of a secondary sale to demonstrate that the sale consideration meets or exceeds FMV.

Angel tax abolished — a major relief. The 2025 Act abolishes the angel tax provision (old Section 56(2)(viib)) which taxed share premium above FMV as “other income” of the issuing company. This removes a major friction point for primary fundraising. However, it does not eliminate the Section 50CA deemed-FMV rule on secondary sales, which continues to apply.

ROFR, Co-Sale and Drag-Along — Tax Implications

Shareholders’ agreements typically contain provisions that affect how and when a founder can exit:

Expert Insight

CA V. Viswanathan: In my founder tax practice at Virtual Auditor, I see the same three mistakes repeated across cohorts — and the Income-tax Act, 2025 has not made them go away. First, founders exercise ESOPs without any thought to the perquisite tax and end up with a ₹30-40 lakh TDS hit in a year when they have no cash. For DPIIT-eligible startups, the 60-month deferral is a lifeline — use it. For non-DPIIT startups, plan the exercise in a low-salary year or coordinate with a secondary sale to fund the tax. Second, founders sell unlisted shares at 22-23 months of holding, thinking they are being “smart” about liquidity — and get hit with STCG at slab rates rather than LTCG at 12.5%. The 24-month holding line is a cliff edge — hold for 25 months minimum. I have seen founders lose ₹60-80 lakh on a single transaction by missing this threshold by weeks. Third, founders ignore Section 54F entirely, treating a primary residence purchase as “separate” from their exit planning. It is not. If you are planning an exit of any size and also considering a home purchase, align them — the Section 54F exemption can shelter the entire LTCG up to ₹10 crore of net consideration. On the 2025 Act specifically: the abolition of angel tax is a welcome move that will reduce primary round friction; the transition to the new regime as default works in favour of most founders during normal years but must be re-evaluated in exercise years; and the DPIIT-linked benefits have become the single most valuable box to tick for every early-stage founder. I urge every founder I advise to do three things immediately for tax year 2026-27: verify DPIIT recognition status, run the regime comparison for both a normal year and a projected exercise year, and map out the holding period for every tranche of equity. These three steps alone cover 80% of founder personal tax exposure under the new Act.

Frequently Asked Questions

How is ESOP taxed for founders under the Income-tax Act, 2025?

In two stages. At exercise, the difference between FMV and the exercise price is taxed as a perquisite under salary. At sale, the difference between sale price and the FMV at exercise is taxed as capital gains. Founder-employees of DPIIT-eligible startups can defer the TDS on the perquisite by up to 60 months.

What is Section 80-IAC and how does it benefit startup founders?

The Section 80-IAC equivalent provides a 100% tax holiday on profits for 3 consecutive years out of the first 10 years for eligible DPIIT-recognised startups. The benefit accrues to the company; founders benefit indirectly through preserved company cash.

How are capital gains on founder shares taxed?

LTCG on unlisted founder shares held more than 24 months is taxed at 12.5% flat without indexation. STCG on unlisted shares is taxed at slab rates. For listed shares held more than 12 months, LTCG is taxed at 12.5% with an annual exemption of ₹1,25,000. STCG on listed equity is taxed at 20%.

Can a founder claim Section 54F exemption on a sale of founder shares?

Yes. Section 54F allows the founder to claim exemption on LTCG from the sale of a long-term capital asset (including founder shares) if the net sale consideration is reinvested in a residential house in India within the prescribed timelines. Cap of ₹10 crore on net consideration applies.

What holding period applies to unlisted founder shares?

More than 24 months to qualify as long-term under the 2025 Act. The holding period for ESOP shares starts from the date of exercise (allotment), not the date of grant or vesting.

What DPIIT benefits are available under the 2025 Act?

DPIIT recognition unlocks the 80-IAC 3-year tax holiday, the ESOP perquisite deferral for founder-employees, and access to government schemes and tenders. Angel tax is abolished under the 2025 Act — a major additional relief for primary fundraising.

Should a founder choose the new or old regime?

The new regime is the default — better for most salaried founders due to generous rebate (nil tax up to ₹12 lakh) and ₹75,000 standard deduction. The old regime can still win with active home loan interest, HRA claim, life insurance premium and significant 80G donations. Re-run the comparison in ESOP exercise years.

How is founder sweat equity taxed?

Same two-stage framework as ESOPs — perquisite at allotment (FMV minus amount paid, often nil) and capital gains at sale (sale price minus FMV at allotment). FMV must be determined under the prescribed valuation rules, typically by a SEBI-registered merchant banker.

How is bonus equity taxed for founders?

Bonus shares are not treated as income at allotment. Cost of acquisition is NIL. On sale, the entire sale consideration is capital gain. Holding period starts from the bonus allotment date — important for the 24-month LTCG threshold.

How do ROFR and co-sale rights impact founder tax planning?

ROFR and co-sale clauses do not change the tax rate — sales are still taxed under capital gains. They can affect timing and structure. Co-sale can reduce the founder’s sale quantum, affecting Section 54F reinvestment planning. Drag-along forces timing without any tax concession.

What is the tax on secondary sales of founder equity?

Secondary sales are taxed as capital gains — LTCG at 12.5% on unlisted shares held more than 24 months, STCG at slab rates otherwise. The Section 50CA deemed-FMV rule applies — the sale consideration must meet or exceed FMV to avoid a deemed addition.

Can a founder avoid ESOP perquisite tax through cashless exercise?

No. Cashless exercise only manages the cash-flow issue — it does not avoid tax. Both the perquisite (at exercise) and the capital gains (at sale) are taxable. For DPIIT-eligible startups, the 60-month deferral is a more meaningful cash-flow tool.

How does the 2025 Act treat angel tax?

The angel tax provision (old Section 56(2)(viib)) is abolished in the Income-tax Act, 2025. Share premium above FMV is no longer taxed as “other income” at the issuing company level. The Section 50CA deemed-FMV rule on secondary sales continues.

How much does founder tax planning cost at Virtual Auditor?

Annual review starts from ₹25,000 covering regime choice, ESOP exercise timing and capital gains planning. Comprehensive pre-exit planning including DPIIT, 80-IAC, ESOP valuation, Section 54F and SHA tax review starts from ₹1,00,000. Pre-IPO or large secondary exits are quoted separately. Contact CA V.
