STP (Systematic Transfer Plan) 2026: Move a Lumpsum Into Equity Gradually — and the Tax Catch

You have a lumpsum — a bonus, a maturity, a property sale — and you want it in equity, but not all at one market level. A Systematic Transfer Plan (STP) solves exactly this: it parks the money in a low-risk fund and automatically moves a fixed amount into an equity fund at regular intervals, so your idle cash earns a return while it averages into the market. Here is how STP works, the three types, and the tax detail most people miss.

What is an STP?

An STP automates transfers from one mutual fund scheme (the source, usually a liquid or debt fund) into another (the target, usually an equity fund) at a set frequency. Both funds must belong to the same fund house (AMC) — you cannot run an STP across two different AMCs. The lumpsum sits in the source fund earning a modest return, and each interval a slice moves into equity, giving you rupee-cost averaging on the deployment.

The three types of STP

The tax catch: every transfer is a redemption

This is the part most investors overlook. Each STP transfer is treated as a redemption from the source fund, so capital-gains tax applies on the gain in the units moved — every single transfer, not just at the end.

Because most STPs run from a debt or liquid source fund, and those are taxed at slab, the tax on the small gains earned in the source fund over a few months is usually modest — but it is real, and it is why an STP is not entirely “free”. The detail is in our capital gains on mutual funds guide.

Minimums and loads

• Minimum transfers: most AMCs require at least 6 transfers.
• Minimum amount: SEBI mandates none, but some AMCs ask for around ₹12,000 to start.
• Exit load: there is no entry load, and transfers from a liquid fund to an equity fund typically attract no exit load — but check the source fund’s exit load rules to be sure.

STP vs lumpsum vs SIP

• vs one-shot lumpsum: STP reduces the risk of investing everything at a market peak, and your money earns a debt-fund return while it waits — better than cash sitting in a savings account.
• vs SIP: a SIP invests fresh income monthly from your bank; an STP deploys a lumpsum you already have. If you have the money now, STP; if you are investing from salary, SIP. Many investors run an STP to deploy a windfall and a SIP for ongoing savings.

And when you eventually want income out of the corpus, the mirror tool is an SWP.

When STP makes sense

Use an STP when you have a meaningful lumpsum, want it in equity over the next 6-18 months, and would rather average in than guess the market. Park it in the AMC’s liquid fund, set a fixed STP into your chosen equity fund, and let it run. It is one of the cleanest, most disciplined ways to put a windfall to work.

Frequently Asked Questions

What is a Systematic Transfer Plan (STP)?

An STP automatically transfers a fixed amount or units from one mutual fund scheme (usually a liquid or debt fund) into another (usually an equity fund) at regular intervals, within the same fund house. It lets you deploy a lumpsum into equity gradually while the money earns a return in the source fund, giving rupee-cost averaging on the deployment.

How is STP taxed?

Each STP transfer is treated as a redemption from the source fund, so capital-gains tax applies on the gain in the units moved at every transfer. If the source is an equity fund, that is 20% STCG under a year or 12.5% LTCG on gains above ₹1.25 lakh a year. If the source is a debt or liquid fund bought on or after 1 April 2023, the gain is taxed at your slab rate. Most STPs run from a debt or liquid fund, so the tax on the modest short-term gains is usually small but not zero.

What are the types of STP?

There are three main types: Fixed STP transfers a fixed rupee amount each interval; Capital Appreciation STP transfers only the gains from the source fund, keeping your capital intact; and Flexi STP transfers a variable amount based on market conditions. Fixed STP is the most common for steadily deploying a lumpsum into equity.

Can I run an STP between two different fund houses?

No. Both the source and target schemes in an STP must belong to the same mutual fund house (AMC). To move money to a different AMC you would redeem and reinvest separately, which is a taxable redemption and may attract exit load. Plan your STP within one AMC that has both a good liquid fund and the equity fund you want.

Is STP better than investing a lumpsum at once?

STP reduces the risk of deploying your entire lumpsum at a market peak and earns a debt-fund return on the money while it waits, which is better than holding cash. A one-shot lumpsum can do better if markets rise steadily after you invest, but it carries more timing risk. For most investors deploying a windfall over 6-18 months, an STP is the more disciplined choice.
