What is Lock-in Period?
Lock-in period is the duration during which investors cannot sell or redeem their investment. Different instruments have different lock-in rules.
Lock-in Period in ELSS
ELSS lock-in: 3 Years from the date of each investment.
Important: For SIP investors, each monthly installment has its own 3-year lock-in. So January 2026 SIP unlocks in January 2029, February 2026 SIP unlocks in February 2029, and so on.
Example
| SIP Date | Unlock Date |
|---|---|
| 1 Jan 2026 | 1 Jan 2029 |
| 1 Feb 2026 | 1 Feb 2029 |
| 1 Mar 2026 | 1 Mar 2029 |
Lock-in Period in IPO
For retail investors: There is no lock-in after listing. You can sell on listing day itself if shares are allotted.
For anchor investors/promoters: SEBI mandates lock-in periods (30-90 days for anchors, 6-18 months for promoters).
