ELSS — the Tax Deduction and the 3-Year Lock-in
An Equity Linked Savings Scheme (ELSS) is an equity mutual fund category that carries a tax deduction and a 3-year lock-in. This lesson explains the deduction, the tax regime it depends on, how the lock-in runs and how gains are taxed, as of October 2026.
What an ELSS is
An Equity Linked Savings Scheme is one of the equity categories in SEBI's scheme categorisation. It holds at least 80% in equity, and the categorisation also allows a passive ELSS.
Two features set it apart from other equity funds: an investment in it qualifies for a deduction from income, and the units cannot be redeemed for 3 years. Because it holds mostly equity shares, its value can fall as well as rise.
The deduction
The deduction is given by section 123 of the Income-tax Act, 2025 (Section 80C of the old 1961 Act). It is up to ₹1.5 lakh a year, a limit shared with all the other items that qualify under the section. Investing more than that in ELSS, or holding several ELSS schemes, does not raise it.
A deduction reduces taxable income; it is not itself the tax saved. The saving depends on the slab rate that would have applied to that slice of income.
The deduction is available only under the old tax regime. The new regime, in section 202 (old Section 115BAC), does not allow it.
The lock-in
ELSS units are locked in for 3 years from the date of allotment. In a SIP each instalment is a separate purchase with its own 3-year lock-in, so the units become free month by month, not all at once three years after the SIP began.
The lock-in belongs to the units, not to the tax claim. It applies whether or not the deduction is claimed, so an investor under the new regime gets no deduction but is still locked in.
Tax when the units are redeemed
After the lock-in, gains are taxed like those of any equity-oriented fund. Units redeemed after 3 years have necessarily been held more than 12 months, so the gain is long-term.
Long-term gains on equity-oriented units are taxed at 12.5% on the amount above ₹1.25 lakh a year, under section 198 (old Section 112A). The ₹1.25 lakh is the taxpayer's single yearly limit across all equity-oriented fund units and listed equity shares, not a separate limit for ELSS.
Rules at a glance
A twelve-month SIP and its lock-ins (illustrative)
Deepa runs a monthly SIP in an ELSS for twelve instalments. Assume, for simplicity, that units are allotted on the 15th of each month from 15 June 2025 to 15 May 2026; in practice allotment moves to the next business day when the 15th is not one, and the fund house confirms the exact date a unit becomes free. Units from the first instalment are free from 15 June 2028; units from the last only from 15 May 2029.
On 20 December 2028 the seven instalments from June to December 2025 have completed 3 years and can be redeemed. The five from January to May 2026 are still locked in.
The shared ₹1.5 lakh limit (illustrative)
- Assumed figures, for arithmetic only: an investor under the old tax regime invests ₹1,00,000 in an ELSS in a year and has ₹80,000 of other items that qualify under section 123.
- Total qualifying amount = ₹1,00,000 + ₹80,000 = ₹1,80,000.
- The deduction is limited to ₹1,50,000, so ₹1,80,000 − ₹1,50,000 = ₹30,000 earns no deduction.
- If that ₹1,50,000 of income would have been taxed at an assumed slab rate of 20%, the tax falls by ₹1,50,000 × 20% = ₹30,000. At an assumed slab rate of 30% it falls by ₹1,50,000 × 30% = ₹45,000. Both figures are before surcharge and cess.
Result. The deduction is ₹1,50,000, not ₹1,80,000, and the tax it saves depends on the slab: ₹30,000 at an assumed 20%, ₹45,000 at an assumed 30%, before surcharge and cess.
Key points
- ELSS investments qualify for a deduction under section 123 of the Income-tax Act, 2025, up to ₹1.5 lakh a year, shared with the other eligible items.
- The deduction is available only under the old tax regime.
- Units are locked in for 3 years from allotment, and each SIP instalment has its own lock-in.
- The lock-in applies even where no deduction is claimed.
- After the lock-in, gains are taxed as for any equity-oriented fund (12.5% on long-term gains above ₹1.25 lakh a year, as of October 2026).
Common misunderstandings
- The ₹1.5 lakh is not a separate limit for ELSS: it is shared with every other item that qualifies under section 123.
- Choosing the new tax regime does not remove the lock-in: there is no deduction, but the units stay locked in for 3 years.
- An ELSS is not a fixed-return product: it holds at least 80% in equity, so its value can fall as well as rise.
Questions people ask
Do two ELSS schemes give two deductions of ₹1.5 lakh?
No. The ₹1.5 lakh is one shared limit, whatever the number of schemes.
Is the gain on ELSS units tax-free after the lock-in?
No. It is taxed like the gain on any equity-oriented fund.
From when does the lock-in run?
From the date of allotment of the units; in a SIP, separately from the allotment date of each instalment.
