ELSS Lock-in Period: Meaning, Duration & Calculation

The lock-in period in ELSS (Equity Linked Savings Scheme) is 3 years from the date of investment, making it the shortest lock-in among all Section 80C tax-saving options. During this period, investors cannot redeem or withdraw their invested amount. Let's check out its meaning, duration & how lock-in calculation works.

Key Takeaways:

• ELSS offers tax benefits under Section 80C and has a 3-year mandatory lock-in.
• Lock-in applies to each investment separately, including SIPs.
• Under the Income Tax Act, 2025, the earlier Section 80C deduction for ELSS has been renumbered as Section 123 from FY 2026–27.

What is the Lock-in Period in ELSS?

The lock-in period in ELSS means that the investor who purchased ELSS funds cannot redeem their units until the predetermined 3-year period from the date of purchase has elapsed. The redemption is based on the units invested.

Types of Mutual funds

Mutual Funds are majorly classified into 2 types such as “Open Ended" Funds & “Closed Ended" Funds 

Open Ended: Open ended funds let you invest and withdraw money at any time, offering high flexibility and liquidity. They have no fixed maturity date, making them suitable for both short term and long term financial goals.

Closed Ended: Closed ended funds always have a lock in period 

Example: In ELSS the lock-in period of 3 years applies to both lump-sum investments and SIP from the day of investment.  

Why is the Lock-in Period in ELSS important?

The lock-in period is essential for both investors and mutual fund houses to maintain the benefits of investing in ELSS. This investment scheme aims to provide long term capital appreciation to investors and avail tax benefits.

This lock in period is very important to ensure the stability of the funds and to prevent liquidity issues by limiting excessive selling that could destabilize them, thereby mitigating short term market fluctuations and creating a conducive environment for sustainable long term growth.

How to Calculate the Lock-in Period?

The lock in period for a lump-sum investment ends after three years from the initial investment date.

Example: Let’s assume you have invested in ELSS through SIP on the following dates and amounts.

• SIP 1: ₹5,000 on January 1, 2026
• SIP 2: ₹5,000 on February 1, 2026
• SIP 3: ₹5,000 on March 1, 2026

Each SIP will have a separate 3-year lock in period.

Lock in is applied to each SIP instalment separately. If one invests ₹5,000 each month, each monthly instalment will have its own 3-year lock-in period from the date of investment. Once the 3-year lock in period for any instalment expires, you can redeem the units from that instalment. 

You cannot redeem part of a specific SIP instalment before the lock in period ends. You’ll need to wait until the full 3-year lock in period has elapsed.

What to do after the Lock-in Period ends?

Once the lock in period ends, it is not mandatory to exit the investment or redeem the funds. One can continue with the same funds by reviewing the fund’s performance and analyzing its investment style and the market impact on its mutual fund.

One may compare the performance of other ELSS mutual fund schemes and transfer units to other funds to save tax. Hence, the ELSS is an open-ended fund that you can redeem or transfer the units at any time. If no emergency fund is needed, staying invested for 5-10 years would generate consistent wealth.

Note: Under the Income Tax Act 2025, the old Section 80C deduction (which included ELSS) has been renumbered to Section 123 from FY 2026-27 onwards. The deduction limit remains ₹1.5 lakh, and ELSS continues to be an eligible investment. However, the deduction is only allowed under the old tax regime. 

Final Word

ELSS mutual funds are an investment choice for those looking to combine long term wealth creation with tax saving benefits. With a mandatory 3-year lock-in, ELSS ensures stability and growth, allowing redemption or transfer of units at the end of the lock-in period.
