Most people know about SIPs, which move money from your bank account into a mutual fund every month. Two lesser-known cousins, STP and SWP, work on the same principle but in different directions. A Systematic Transfer Plan (STP) moves money from one fund to another. A Systematic Withdrawal Plan (SWP) moves money from a fund back to your bank account.
Both are useful tools, especially for investing a large sum gradually and for drawing a regular income in retirement. This guide covers how each works, what it costs in tax, and where it fits.
What is a Systematic Transfer Plan (STP)?
An STP lets you invest a lump sum in one scheme (usually a liquid or other low-risk debt fund) and transfer a fixed amount at regular intervals into another scheme (usually an equity fund) of the same fund house.
It is often used when someone receives a large amount — a bonus, a property sale, maturity proceeds — and doesn't want to put it all into equity on a single day.
How it works:
- You invest the lump sum in the source fund.
- You choose the target fund, the transfer amount and the frequency (daily, weekly or monthly).
- On each date, units of the source fund are redeemed and the money is invested in the target fund at that day's NAV.
- Meanwhile, the balance in the source fund keeps earning whatever that fund earns.
Example. Ramesh receives ₹12 lakh and invests it in a liquid fund, with an STP of ₹1 lakh a month into a flexi cap fund. Over 12 months, his equity exposure builds up gradually, and he gets the benefit of rupee-cost averaging, similar to a SIP.
Some fund houses also offer variations, such as a "capital appreciation STP" that transfers only the gains of the source fund, or flexible STPs that transfer more when markets fall. Features differ between fund houses.
Tax and costs on an STP
Every STP transfer is technically a redemption from the source fund, so:
- Capital gains tax applies to the gain portion of each transfer. If the source is a debt fund bought after 1 April 2023, the gain is taxed at your slab rate. Because liquid funds usually grow slowly, the gain on each transfer is typically small.
- Exit load may apply if the source fund has one for the period you've held the units.
Units bought in the target fund start a fresh holding period from their own allotment date.
What is a Systematic Withdrawal Plan (SWP)?
An SWP lets you withdraw a fixed amount from a mutual fund at regular intervals — usually monthly — while the rest stays invested. The fund redeems just enough units on each date to pay you the chosen amount.
People use SWPs for:
- Retirement income from a corpus built over the years
- Regular payouts for a dependent, such as a parent or a child studying away from home
- Planned exits, taking money out gradually rather than all at once
How SWP withdrawals are taxed
This is where SWPs have a real advantage over interest income. When you withdraw through an SWP, you are selling units. Only the gain on the units sold is taxable — the part that is your own original capital is not.
Worked example.
- You invest ₹10,00,000 in a fund at an NAV of ₹20, so you get 50,000 units.
- Two years later, the NAV is ₹25. You withdraw ₹20,000.
- Units redeemed: ₹20,000 ÷ ₹25 = 800 units.
- Cost of those units: 800 × ₹20 = ₹16,000.
- Taxable gain: ₹4,000, not ₹20,000.
Compare that with ₹20,000 of fixed deposit interest, where the whole amount is added to your taxable income.
How that ₹4,000 is taxed depends on the fund:
| Fund type | Holding period | Tax on gains (FY 2025-26) |
|---|---|---|
| Equity-oriented | Up to 12 months | 20% (STCG) |
| Equity-oriented | More than 12 months | 12.5% on gains above ₹1.25 lakh a year (LTCG) |
| Debt fund bought on/after 1 April 2023 | Any | Slab rate |
Units are redeemed on a first-in, first-out basis, so the oldest units go first. Tax rules can change in any Budget, so check the current position before you set up a long SWP. Our article on capital gains tax on mutual funds and shares explains the rules in more detail.
With an SWP, only the gain portion of each withdrawal is taxed, not the full amount you receive.
Using SWP for retirement income
An SWP can turn a retirement corpus into something that feels like a monthly salary. A few principles help it last:
- Keep the withdrawal rate sensible. If you withdraw more each year than the portfolio earns, you eat into capital. Withdraw too much and the corpus can run out early. A lower withdrawal rate gives more room for bad years.
- Plan for inflation. A withdrawal that covers expenses today will cover less in ten years. Some retirees raise the SWP amount every year or two.
- Mind the sequence. A sharp market fall in the early years of retirement, while you are withdrawing, can do lasting damage. That is why many retirees don't run an SWP purely from equity.
- Use buckets. One common approach is to keep two to three years of expenses in liquid or short-duration debt funds and run the SWP from there, while a separate equity portion has time to grow and periodically refills the debt bucket.
You can test how long a corpus might last at different withdrawal and return assumptions using our retirement calculator. If you are also building retirement savings through NPS, see our guide on NPS explained.
Mutual fund investments are subject to market risks; read all scheme-related documents carefully.

| SIP | STP | SWP | |
|---|---|---|---|
| Money moves from | Bank account | One fund | Fund |
| Money moves to | Fund | Another fund (same fund house) | Bank account |
| Main use | Building wealth | Investing a lump sum gradually | Regular income or gradual exit |
| Taxable event? | No | Yes, on each transfer | Yes, on each withdrawal |
Frequently asked questions
Can I do an STP between two different fund houses?
No. An STP works only between schemes of the same fund house. To move money across fund houses, you would redeem from one and invest in the other separately.
Is SWP better than a fixed deposit for monthly income?
They suit different needs. An FD offers a fixed rate and capital stability, but all interest is taxable. An SWP can be more tax-efficient because only gains are taxed, but the value of the fund can fall, so income is not guaranteed in the same way.
Can I change or stop an SWP?
Yes. You can usually change the amount, the date or stop the SWP by submitting a request to the fund house or through your investment platform.
Does an SWP attract exit load?
It can, if units redeemed are still within the scheme's exit load period. Many investors start an SWP only after that period has passed.
Key takeaways
- An STP moves money gradually from one fund to another in the same fund house; an SWP pays money from a fund to your bank.
- Each STP transfer and SWP withdrawal is a redemption and can attract capital gains tax and exit load.
- In an SWP, only the gain portion of each withdrawal is taxed.
- For retirement income, keep withdrawals sustainable, allow for inflation and consider a bucket approach.
