Yes, Systematic Investment Plans (SIP) can be used to invest in Tax saving mutual funds. SIP allows investors to invest a fixed amount regularly, which is especially beneficial for salaried individuals. Each SIP installment in tax saving mutual funds is treated as a separate investment with its own three-year lock-in period. This disciplined approach not only helps in tax planning but also averages out market volatility, potentially offering better long-term returns. SIPs are an excellent way to build a habit of regular investing while saving on taxes.
