STP
A Systematic Transfer Plan (STP) is a facility that allows an investor to automatically transfer a fixed or variable amount from one mutual fund scheme to another within the same AMC at regular intervals. It is commonly used to gradually shift a lump sum from a liquid or debt fund into an equity fund, reducing timing risk.
A Systematic Transfer Plan (STP) is essentially a SIP funded from within a mutual fund rather than from a bank account. The investor parks a lump sum in a source scheme — typically a liquid fund or overnight fund — and instructs the AMC to transfer a fixed amount periodically into a target scheme, usually an equity or hybrid fund. This transfer happens by redeeming units from the source and purchasing units in the target at applicable NAVs on the transfer date.
The primary use case for STP is deploying a large corpus into equity markets in a disciplined, phased manner. Instead of investing a windfall — such as a bonus, inheritance, or maturity proceeds — as a lump sum into equity, an investor can park it in a liquid fund earning 6-7% and transfer Rs 50,000 each month into a target equity fund over 12-18 months. This provides the dual benefit of earning returns on the idle corpus while averaging the equity entry cost over time.
There are two main types of STPs. A Fixed STP transfers a constant amount each interval regardless of market conditions. A Variable STP (also called Flex STP) transfers more when markets are down and less when markets are up, by setting a floor and ceiling amount. Variable STP is conceptually more sophisticated but requires careful monitoring.
From a taxation standpoint, each STP transfer from the source scheme is treated as a redemption and is subject to capital gains tax. If the source scheme is a debt fund, gains are taxed as per the investor's income tax slab (post-April 2023 amendment). This tax implication is often overlooked by investors who treat STP as a neutral transfer mechanism.
STP differs from SIP in one critical way: with SIP, the investor's bank account is debited; with STP, units of the source fund are redeemed. Both achieve phased equity exposure, but STP is better suited for investors who already have a large corpus to deploy rather than those making fresh monthly investments from income.
