An equity linked savings scheme (ELSS) is tax-saving mutual fund scheme that helps you save taxes and generate reasonable income at the same time. According to the Securities & Exchange Board of Inia (SEBI), a minimum of 80% of the assets within the ELSS mutual fund must go into equity. Meanwhile, a portion of the underlying assets can be secured into low risk fixed income securities like government bonds to balance out the portfolio.

ELSS funds have a lock-in period of 3 years, the lowest among all other tax saving instruments like public provident fund (PPFs) and fixed deposit (FDs). However, it is essential to note that there is no way to redeem your units within the lock-in period.

SIP Vs Lumpsum: Understanding the differences

Getting a thorough overview of the key differences in SIP and lumpsum -

Differentials	Systematic investment plan (SIP)	Lumpsum
Definition	A strategic plan to invest a set amount of money at regular intervals (weekly, monthly or quarterly) in mutual funds. This amount is automatically deducted from the investors based on the interval selected.	Lumpsum investments refers to one-time payment made at the start of the investment period. This is the case when investors choose to invest all the money available in mutual funds or another instrument.
Advantages	Disciplined approach avoids impulsive decision making to market conditions, preventing heavy losses. Investors gains more units of mutual funds during market downfall and less units if market goes up. In the long term, this limits the average cost per unit. Investors can give auto-debit instructions and automate instalment deduction, making SIPs hassle-free. Excellent tool for the newbies who want to test mutual fund investment with a small amount.	Lumpsump means investing large amounts of money, meaning you have greater chances at earning higher returns. You can take advantage of market changes to gain more profits when the conditions are favorable. There are no time constraints in this investment, you can invest whenever you want and often withdraw as and when you want.
Disadvantages	You have limited control since the investments cannot be timed with the market and must stick to the regular schedules (weekly, monthly or quarterly). You cannot leverage market fluctuations and invest large amounts of money when the market conditions are favorable, prohibiting you from making more money.	These investments rely heavily on market timing. If you get the timing wrong, you can incur substantial losses. These investments, unlike SIP, are harder to manage as they ask investors to make a one-time decision about the amount of money they want to invest and timing.
