Do tax-saving funds' 3-year lock-in apply to each SIP?

Summary: A reader asks how the three-year lock-in period works for ELSS funds when investing through a SIP. The answer touches on tax implications and how this popular investment option fits into different tax regimes.

When you invest in an ELSS fund through an SIP, each monthly instalment starts its own independent three-year lock-in from the date it is invested. This is different from a lump-sum investment, where a single date governs the entire amount. For investors, this means the question is not "when does my ELSS SIP unlock?" but "when does each instalment unlock?"

ELSS, or equity-linked savings scheme, is a category of equity mutual fund required to invest at least 80 per cent of its portfolio in equity and equity-related instruments, per SEBI's categorisation framework. The three-year lock-in period per unit is a statutory requirement. Per SEBI's categorisation guidelines, no unit, whether purchased via SIP or lumpsum, can be redeemed before three years have elapsed from its investment date.

The per-instalment lock-in is the core mechanic that governs everything else about ELSS SIP redemption: your exit timeline, your tax planning, and even the decision of whether stopping the SIP makes financial sense.

What happens if you stop your SIPs in an ELSS fund?

Stopping an ELSS SIP does not unlock the money already invested. Each instalment already contributed continues to follow its own three-year lock-in from its original investment date — stopping the SIP instruction simply means no new instalments are added. For investors, this is a meaningful distinction: cancelling the SIP and accessing the invested money are two separate decisions.

If you are stopping the SIP due to a cash-flow need, check first whether any instalments have already completed their three-year lock-in and become redeemable. Instalments made more than three years ago can be partially redeemed without affecting newer, still-locked units. The gap between direct and regular ELSS plan expense ratios, typically around 1-1.5 percentage points, compounds across every locked-in year, making a review of your plan type worthwhile even if you are pausing contributions.

When can you fully exit an ELSS fund? 

When an investor completes a 36-month ELSS SIP, the last instalment's maturity date, not the first, determines when full exit is possible. For instance, if you initiate SIPs in an ELSS fund starting April 2026, you will be able to redeem the investment 36 months later, i.e., in April 2029.

Partial exit is available: any instalment whose three-year period has elapsed can be redeemed independently while newer units remain locked. A staggered monthly exit, or redeeming mature units as each one clears its lock-in, is a commonly discussed strategy for investors who want liquidity without a single lump-sum exit decision.

What tax applies when you redeem ELSS units?

When ELSS units are redeemed after the mandatory three-year lock-in, any gains are treated as long-term capital gains (LTCG). For investors, this means ELSS redemptions are subject to the same LTCG tax framework as any equity mutual fund: the lock-in is not a tax exemption; it is a condition for the 80C benefit at the time of investment.

The current LTCG tax rate on equity mutual fund redemptions is 12.5 per cent, with gains up to Rs 1.25 lakh per financial year exempt. At the investment stage, ELSS qualifies for a Section 80C deduction of up to Rs 1.5 lakh per financial year, but only for investors who have opted for the old tax regime. Investors in the new tax regime cannot claim the Section 80C deduction for ELSS, as the new regime does not permit deductions of this kind.

Frequently asked questions (FAQs)

Can I do a systematic transfer plan (STP) into ELSS, and does each transfer carry its own lock-in?

An STP into an ELSS fund transfers amounts on a scheduled basis from another fund. Each transfer is treated as a fresh ELSS investment from its transfer date, starting its own three-year lock-in, the same logic as a SIP instalment. Confirm operational treatment with your fund house, as STP eligibility for ELSS may vary by fund house.

Is there an exit load on ELSS after the lock-in period ends?

ELSS funds do not carry an exit load once each unit's three-year lock-in has elapsed. For investors, the only cost at redemption for mature ELSS units is the applicable LTCG tax. Per current SEBI norms, exit loads are not permitted on ELSS units after the mandatory lock-in period has elapsed.

If I switch from one ELSS fund to another, does the lock-in reset?

Switching between ELSS funds is treated as a redemption of the first fund and a fresh investment in the second. The lock-in clock resets to zero on the new fund's investment date. Switching within the lock-in period is not permitted; units cannot be redeemed or switched out before their individual three-year lock-in has elapsed.

Can ELSS still work for investors on the new tax regime?

Under the new tax regime, no Section 80C deduction is available for ELSS investments. ELSS functions as a standard equity mutual fund with a mandatory three-year lock-in: equity growth potential remains intact, but the tax benefit at entry does not apply. Whether the lock-in structure suits a new-regime investor depends on their liquidity needs and preference for behavioural discipline in equity investing.

Key takeaways

Stopping the SIP does not unlock your money: Cancelling an ELSS SIP stops new contributions only. All existing units remain locked for their individual three-year periods. Check which instalments have already matured before assuming nothing is available.

Tax at entry is not the same as tax at exit: ELSS offers a potential Section 80C deduction of up to Rs 1.5 lakh per year at the investment stage under the old tax regime. At exit, gains are subject to LTCG tax at 12.5 per cent above the Rs 1.25 lakh annual exemption. Both figures affect the net benefit of ELSS versus a standard equity fund and should be factored into any investment decision.
