SEBI 2025 Overnight-Fund Cut-Off Change: What It Means for Parking Idle Cash Post-Tax

Idle current-account and savings-account balances are the quiet drag on most household and treasury portfolios. Money that sits waiting for a school fee, an advance-tax instalment or the next equity dip earns a deregulated savings rate that many banks have parked near 2.5% to 3% since the Reserve Bank of India freed savings-deposit pricing on 25 October 2011. An overnight mutual fund is the competing home for that same cash, and a Securities and Exchange Board of India (SEBI) circular that took effect on 1 June 2025 has made it materially more usable for same-day liquidity. This piece compares an overnight fund against a savings account for parking idle cash, on a strictly post-tax basis, using only figures traceable to SEBI, the Income-tax Department, the RBI and AMFI.

How SEBI's 1 June 2025 Cut-Off Change Actually Works

The relevant instrument is SEBI circular SEBI/HO/IMD/PoD2/P/CIR/2025/56, dated 22 April 2025, which modified paragraph 8.4.5.4 of the Master Circular for Mutual Funds dated 27 June 2024. The circular came into force on 1 June 2025 and was issued under Section 11(1) of the SEBI Act 1992 read with Regulation 49 of the SEBI (Mutual Funds) Regulations 1996.

Before the change, a redemption request in a liquid or overnight scheme followed a single 3:00 pm cut-off. Under the revised paragraph 8.4.5.4, that structure remains for offline requests: an application received up to 3:00 pm gets the closing net asset value (NAV) of the day immediately preceding the next business day, and one received after 3:00 pm gets the closing NAV of the next business day. The operative addition is a proviso that, for overnight fund schemes only, a request placed through online mode is honoured against a 7:00 pm cut-off. In practice that pushes the deadline for capturing the relevant NAV back by four hours for online investors in overnight funds.

SEBI did not design this for retail convenience alone. Paragraph 1 of the circular ties the change to the "upstreaming" framework of 12 December 2023, which requires stock brokers and clearing members to place clients' clear credit balances with clearing corporations on an end-of-day basis, in the form of cash, a lien on fixed-deposit receipts, or a pledge of units of Mutual Fund Overnight Schemes. A working group of industry participants, the Association of Mutual Funds in India (AMFI) and the Mutual Funds Advisory Committee recommended the later cut-off so that brokers could operationalise the pledge route; SEBI put the proposal through public consultation before finalising it in the 22 April 2025 circular. For an ordinary investor, the useful by-product is that idle money placed online in an overnight fund now has a longer same-day window before it rolls to the next business day's NAV.

Side-by-Side Comparison

An overnight fund is a debt scheme that invests in securities maturing in a single business day, such as tri-party repo (TREPS), reverse repo and one-day money-market instruments. Its return therefore tracks the overnight money-market rate, which sits inside the RBI's liquidity corridor: after the Monetary Policy Committee's unanimous hold on 5 August 2026, the repo rate is 5.25%, the Standing Deposit Facility (SDF) rate 5.00% and the Marginal Standing Facility (MSF) rate 5.50%. A savings account, by contrast, pays a bank-set deregulated rate and carries deposit insurance from the Deposit Insurance and Credit Guarantee Corporation (DICGC) up to Rs 5,00,000 per depositor per bank, a cover raised from Rs 1,00,000 with effect from 4 February 2020.

The table below sets out the practical differences relevant to parking idle cash, current as of the 1 June 2025 rule change.

The redemption mechanics matter more than the headline yield gap. A savings account offers instant, round-the-clock withdrawal; an overnight fund, even after 1 June 2025, still settles on a business-day cycle, so money is not available on a Sunday or a money-market holiday. The circular's own explanation clarifies that a "business day" excludes any day on which the money markets are closed or otherwise inaccessible.

Tax Treatment

This is where the comparison is most often misunderstood. Since the Finance Act 2023 inserted Section 50AA of the Income-tax Act 1961, gains on units of a specified mutual fund acquired on or after 1 April 2023 are deemed short-term capital gains and taxed at the investor's applicable slab rate, irrespective of holding period. Overnight funds, being debt-oriented, fall squarely within this treatment: there is no concessional long-term rate, no 12.5% option and no indexation benefit. The gain is recognised only on redemption, which is the single genuine tax edge over a savings account.

Savings-account interest is taxed differently in timing rather than in rate. It is added to total income and taxed at the slab rate every financial year on accrual, whether or not it is withdrawn. Individuals under the old regime may claim a deduction of up to Rs 10,000 under Section 80TTA (Rs 50,000 under Section 80TTB for resident senior citizens on deposit interest), but neither deduction is available under the new regime governed by Section 115BAC. Under the new-regime slabs for FY 2025-26, income up to Rs 4,00,000 is nil-rated, the Rs 4,00,000 to Rs 8,00,000 band is taxed at 5%, and the top 30% rate begins above Rs 24,00,000, with a Section 87A rebate of up to Rs 60,000 fully sheltering total income up to Rs 12,00,000. A 4% health and education cess applies on the tax in every case.

The contrast with equity is worth stating so investors do not misapply the wrong rate. For comparison, equity mutual funds attract long-term capital gains at 12.5% above a Rs 1,25,000 annual exemption and short-term gains at 20%, both set by Budget 2024 with effect from 23 July 2024. None of those equity rates apply to an overnight fund.

The deferral is the point. Because an overnight fund is taxed only when you sell, a large balance kept for several months can compound gross and settle the tax bill once, whereas savings interest is taxed each year even if left untouched. For a taxpayer in the 30% slab, the effective rate on both is 31.2% after the 4% cess, so the timing of recognition, not the rate, is what separates them.

Who Should Pick Which

The right home for idle cash depends on the horizon, the balance and the marginal tax slab. A useful way to see it is to model an illustrative overnight-fund yield equal to the 5.00% SDF corridor floor as of 5 August 2026 (used only as a proxy, since actual scheme returns vary and must be read from AMFI-published data) and compare post-tax outcomes across slabs.

Set against a savings account paying an illustrative 3.00%, the same 30%-slab investor nets about 2.06% after tax, before applying the Section 80TTA shelter of up to Rs 10,000 on savings interest in the old regime. The gap narrows sharply for very small balances, where the 80TTA deduction can leave savings interest effectively untaxed, and widens for six- and seven-figure treasury floats.

A saver keeping only a modest buffer of a few weeks, or one who needs money on weekends and holidays, is generally better served by a savings account: the instant 24x7 access and DICGC cover up to Rs 5,00,000 outweigh a fractional yield pick-up. A business or high-net-worth individual parking a large float for two to eight weeks, comfortable with a business-day settlement and online redemption by the new 7:00 pm cut-off, is the natural user of an overnight fund, especially in the 20% or 30% slab where tax deferral compounds. Anyone whose horizon stretches beyond a few months should instead compare a fixed deposit using the FD calculator or a longer-dated plan such as PPF via the PPF calculator, rather than leaving the money in either an overnight fund or a savings account.

Before committing a lump sum, model the outcome on the lumpsum calculator and cross-check realised returns against benchmarks on the mutual-fund returns calculator. It helps to be precise about the vocabulary too: the NAV is the price at which units are bought and redeemed, an overnight scheme is a debt fund for tax purposes, the tax head in play is STCG rather than LTCG, and settlement speed is a question of liquidity rather than of guaranteed return.

FAQ

What changed for overnight funds on 1 June 2025?

SEBI circular SEBI/HO/IMD/PoD2/P/CIR/2025/56 of 22 April 2025 modified paragraph 8.4.5.4 of the 27 June 2024 Master Circular for Mutual Funds and, from 1 June 2025, allowed a 7:00 pm cut-off for online redemption requests in overnight fund schemes, alongside the existing 3:00 pm offline cut-off.

Do I get same-day money if I redeem an overnight fund online at 6:30 pm?

You capture the NAV determined by the 7:00 pm online cut-off for overnight schemes under the revised paragraph 8.4.5.4, but actual credit still follows the business-day settlement cycle. The circular's explanation states that a "business day" excludes any day on which the money markets are closed, so weekend and holiday redemptions do not settle same-day.

How are overnight fund gains taxed in 2026?

As a debt-oriented scheme, an overnight fund bought on or after 1 April 2023 is a specified mutual fund under Section 50AA of the Income-tax Act 1961, so its gains are taxed at your slab rate as short-term capital gains regardless of holding period, with no indexation and no 12.5% long-term rate. The 4% cess applies on the tax.

Is a savings account safer than an overnight fund?

A savings account carries DICGC deposit insurance up to Rs 5,00,000 per depositor per bank, a limit in force since 4 February 2020, whereas an overnight fund is market-linked and not guaranteed. Overnight funds carry very low but non-zero risk because they hold one-business-day paper priced near the RBI corridor (SDF 5.00% as of 5 August 2026).

Can I claim any deduction on savings-account interest?

Under the old regime, Section 80TTA allows a deduction of up to Rs 10,000 on savings-account interest for individuals and HUFs, and Section 80TTB allows up to Rs 50,000 for resident senior citizens on deposit interest. Neither deduction is available under the new regime under Section 115BAC.

Does the new 7:00 pm cut-off apply to liquid funds too?

No. The revised paragraph 8.4.5.4 retains the 3:00 pm cut-off framework for liquid and overnight funds generally, and the extended 7:00 pm online cut-off is expressly a proviso for overnight fund schemes only, effective 1 June 2025.

Where does the overnight fund's yield come from?

It reflects returns on one-business-day instruments such as TREPS and reverse repo, which trade near the RBI's overnight corridor. After the 5 August 2026 Monetary Policy Committee decision, the repo rate is 5.25%, the SDF 5.00% and the MSF 5.50%; scheme-level returns must be read from AMFI-published data rather than assumed.
