Debt Mutual Funds Taxation in India — LTCG, STCG and the New Rules Explained

Last Updated: August 2026

Quick answer: If you bought your debt mutual fund on or after 1st April 2023, every rupee of gain is taxed at your income tax slab rate — no matter how long you hold it. If you bought it before 1st April 2023 and sell it after 23rd July 2024, your long-term gains are taxed at a flat 12.5%, but without indexation. So there are two different rules, depending purely on your purchase date. Most investors can get this wrong, so I’ve highlighted it. Let’s read more about it.

Introduction

Debt Mutual Funds Taxation is one of those topics that keeps changing just when you think you’ve understood it.

This article was first written when the Finance Bill 2023 was passed in the Lok Sabha. At that time, the bill was aimed at bringing debt mutual funds at par with bank fixed deposits.

That was a big change. But it wasn’t the last one. In July 2024, the government made a second, equally important change.

If you’re still calculating your tax based on the 2023 rule alone, you’re either overpaying or underpaying, depending on when you bought your units.

Broadly speaking, there are two types of mutual funds:

• Equity funds: Equity mutual funds primarily invest in company shares.
• Debt funds: These funds invest in fixed-return instruments such as government bonds or corporate bonds.

This article is only about how the debt returns are taxed.

Here’s the one line that decides which rule applies to you: as of date, your purchase date, not your sale date, decides your tax treatment.

How Debt Funds Were Taxed Before 2023

Previously, if an investor held debt fund units for more than three years, the gains qualified as LTCG (long-term capital gains) and were taxed at a rate of 20% with indexation benefit.

Indexation allowed investors to inflate the purchase price of their units in line with inflation, using the Cost Inflation Index (CII).

A higher adjusted purchase price meant a lower booked profit, and hence a lower tax.

In a country like India, where inflation isn’t exactly low, this benefit meaningfully reduced the effective tax rate. It can sometimes go down to single digits over a long holding period.

The Problem With The Old Tax Regime

Debt mutual funds are one form of debt instrument. Bank fixed deposits are another.

There was a disparity between the two:

• Gains from FDs are taxed every year at the investor’s slab rate, with no LTCG treatment and no indexation.
• But a debt mutual fund holding the same kind of paper (mainly bonds) was being taxed at a much lower effective rate after three years. And how was this happening? Purely because of the indexation benefit.

Suppose a person is in the 30% tax slab.

If he liquidates a bank FD, the interest is taxed at 30%.

But if he holds a debt mutual fund for five years, his effective tax after indexation could work out to something like 8%.

So you can see, for this investor, there was the same underlying risk if he held an FD or a debt fund, but he used to get a wildly different tax outcome.

That’s the disparity the government set out to fix.

Change #1: What Happened From 1st April 2023

The Finance Act 2023 introduced Section 50AA of the Income Tax Act.

Under this section, gains on debt mutual fund units purchased on or after 1st April 2023 are deemed to be short-term capital gains. This would be regardless of how long you actually hold them.

Indexation is gone completely for these units.

You pay tax at your income tax slab rate, exactly like FD interest.

This new rule applies only to what the Act calls a “Specified Mutual Fund.” This means any mutual fund that invests 35% or less in direct equity (shares).

What if you bought your units before 1st April 2023?

Then you were not affected by this rule. You kept the old benefit. LTCG at 20% with indexation benefits will be applicable for you.

But this protection did not last forever. It changed again in July 2024, which we cover next.

Change #2: What Happened From 23rd July 2024

The Union Budget presented on 23rd July 2024 rationalised capital gains tax across nearly every asset class.

For debt mutual funds bought before 1st April 2023, the ones that had been grandfathered under the old rule, here’s what changed:

If you sell these units on or after 23rd July 2024, and you’ve held them for more than 24 months, your LTCG is now taxed at a flat 12.5% without indexation (down from 20% with indexation).

Notice the changes:

• The indexation benefit that made debt funds attractive over FDs in the first place is now gone for everyone. Whether you bought before or after April 2023, the indexation benefit will not be accounted.
• The only benefit that investors who bought debt funds before April 2023 got was a lower tax rate of 12.5% instead of 20%.

Let’s see the full picture, laid out for you by the purchase date of the units

Purchase Date	Sale Date	Holding Period	Tax Treatment
Before 1 Apr 2023	Before 23 Jul 2024	Over 3 years	LTCG at 20% with indexation
Before 1 Apr 2023	Before 23 Jul 2024	Under 3 years	STCG at slab rate
Before 1 Apr 2023	On/after 23 Jul 2024	Over 24 months	LTCG at 12.5%, no indexation
Before 1 Apr 2023	On/after 23 Jul 2024	Under 24 months	STCG at slab rate
On/after 1 Apr 2023	Any date	Any holding period	Deemed STCG at slab rate, always

It will be worth asking CA if he is aware of this finer detail. If not, you can forward this post to him. 🙂

Change #3: The Definition Itself Got Narrower (FY 2025-26 Onward)

This is the detail that can get ignored very easily.

It matters if you hold Gold ETFs or international/overseas fund-of-funds.

When Section 50AA was first introduced, “Specified Mutual Fund” was defined loosely. It was any fund with 35% or less in domestic equity, right?

That accidentally swept in Gold ETFs, international equity FoFs, and similar funds that aren’t really “debt” funds in the way most of us think about them.

But the Finance (No. 2) Act 2024 fixed this.

Effective from FY 2025-26 (AY 2026-27). The definition now requires the “Specified Mutual Fund” to invest more than 65% of its proceeds in debt and money market instruments to be classified as one.

So what happened as a consequence:

• Gold ETFs and international funds are now outside Section 50AA entirely and go back to being taxed under the normal long-term/short-term asset rules.
• If you hold a Gold ETF or an international fund and were taxing it like a debt fund, that’s no longer correct from FY 2025-26 onward.

Two Things People Confuse With Capital Gains Tax

TDS on IDCW payouts. Why?

[IDCW = Income Distribution cum Capital Withdrawal, what used to be called “dividend”]

• If your debt fund pays out income (IDCW) that is a separate matter from capital gains tax.
• You get IDCW payouts while you hold the fund. Capital gains tax applies only when you sell it.

These are two different events, taxed in two different ways.

• IDCW from Debt Fund: Under Section 194K, the fund house deducts 10% TDS if your total IDCW payout from that one AMC crosses Rs. 5,000 in a financial year. This TDS happens automatically, whether or not you ever sell your units.

Can you set off a long-term loss against this “short-term” gain? This one is trickier, so let’s use an example.

Suppose you sold some shares last year and booked a long-term capital loss of Rs. 50,000. This year, you redeem a debt fund you bought in 2022 (before April 2023) and held for over 24 months.

As we explained above, this gain is taxed at a flat 12.5%. It is treated as “long-term” for the tax rate.

Now suppose instead you bought that same debt fund after April 2023. Section 50AA says this gain is taxed as short-term, at your slab rate — even though you held it for the same 24+ months.

Here is the question this raises: can you use your Rs. 50,000 long-term loss to reduce this gain?

Normally, a long-term loss can only be set off against long-term gains (not short-term ones). But the unit itself, held over 24 months, is still technically a long-term asset.

Only its gain is being taxed as short-term, not the asset’s actual character.

So is this set-off allowed or not? Most tax experts treat it as not allowed. I’ll also play it safe for myself. I’ll assume we cannot set off a long-term loss against this gain.

What Type Of Investors Are Most Affected?

Let’s look at the current income tax slabs under the new tax regime (FY 2025-26 / AY 2026-27), since debt fund gains under Section 50AA are taxed exactly like any other slab-rate income:

Income Slab	Tax Rate
Up to Rs. 4 lakh	Nil
Rs. 4 lakh – Rs. 8 lakh	5%
Rs. 8 lakh – Rs. 12 lakh	10%
Rs. 12 lakh – Rs. 16 lakh	15%
Rs. 16 lakh – Rs. 20 lakh	20%
Rs. 20 lakh – Rs. 24 lakh	25%
Above Rs. 24 lakh	30%

Under Section 87A, a resident individual with taxable income up to Rs. 12 lakh gets a rebate of up to Rs. 60,000. This effectively makes tax nil up to that point. Salaried individuals get a further Rs. 75,000 standard deduction on top, pushing the effective zero-tax threshold to about Rs. 12.75 lakh.

Worth knowing: this rebate applies to your slab-rate income, including deemed-STCG gains from debt funds under Section 50AA, but it does not apply to the flat 12.5% LTCG on pre-2023 units — that’s taxed as “special rate” income and sits outside the rebate calculation.

Example: Same Investment, Three Different Outcomes

Let’s use real purchase and sale years.

In every case, assume Rs. 1,00,000 invested in a debt fund compounding at a 10% CAGR.

Scenario 1 — Bought Feb 2018 (FY 2018-19), sold March 2023 (FY 2022-23).

This is a pre-2023 unit sold entirely under the old regime. Realistic for someone reviewing a debt fund they exited a couple of years ago.

• Holding period: 5 years → maturity value = ₹1,00,000 × 1.10⁵ = ₹1,61,051 → gain = ₹61,051
• CII for FY 2018-19 = 280, CII for FY 2022-23 = 331
• Indexed cost = Rs. 1,00,000 × (331 ÷ 280) = Rs. 1,18,214
• Indexed gain = Rs. 1,61,051 − Rs. 1,18,214 = Rs. 42,837
• Tax @ 20% = Rs. 8,567
• Effective tax rate on the actual Rs. 61,051 gain: ~14.0%

Scenario 2 — Bought Feb 2019 (FY 2019-20), sold now in August 2026 (FY 2026-27).

This is the one most relevant to you if you’re holding an old debt fund purchased before April 2023 and are deciding whether to redeem it today.

• Holding period: ~7.5 years → maturity value = Rs. 1,00,000 × 1.10^7.5 ≈ Rs. 2,04,400 → gain ≈ Rs. 1,04,400
• Sold after 23 July 2024 and held over 24 months, so: flat 12.5%, no indexation, regardless of CII
• Tax @ 12.5% = Rs. 13,050
• Effective tax rate on the gain: exactly 12.5%, by definition

Scenario 3 — Bought April 2023 (FY 2023-24), sold now in August 2026 (FY 2026-27).

This is the maximum holding period currently possible for any unit bought under the post-2023 rule. Nobody has held a Section 50AA unit for more than about 3.3 years yet, because the rule itself is only that old.

• Holding period: ~3.3 years → maturity value = Rs. 1,00,000 × 1.10^3.3 ≈ Rs. 1,37,350 → gain ≈ Rs. 37,350
• Deemed STCG at slab rate — taking a 30% bracket investor: tax = Rs. 11,205
• Effective tax rate on the gain: exactly 30%, by definition

The counterintuitive part: look closely at Scenario 1 versus Scenario 2.

• The old 20%-with-indexation regime worked out to an effective ~14% here.
• The current flat 12.5% rate — the one everyone assumes is a worse deal because indexation is gone, is actually lower. That’s not a coincidence specific to these numbers; it happens whenever your fund’s nominal growth comfortably outpaces inflation, because indexation only ever shelters you from the inflation component of your gain, not the whole gain.
• In a period of strong fund returns and moderate inflation (roughly what India has seen through 2018–2023), losing indexation but getting a lower flat rate can be close to a wash — sometimes even better.
• It’s Scenario 3, the post-2023 slab-rate treatment, that’s the genuinely expensive outcome for anyone above the 20% bracket — not the pre-2023-units-sold-today case people usually worry about most.

Scenario 3 isn’t a single number — it depends entirely on your slab. Unlike Scenarios 1 and 2, where the rate is fixed regardless of who you are, a post-2023 debt fund gain just gets added to your income and taxed at whatever slab it falls into. Here’s the same ₹37,350 gain from Scenario 3, taxed across the current FY 2025-26 slabs:

Your Slab Rate	Tax on ₹37,350 Gain	Effective Rate
5%	₹1,868	5%
10%	₹3,735	10%
15%	₹5,603	15%
20%	₹7,470	20%
25%	₹9,338	25%
30%	₹11,205	30%

If your total taxable income (including this gain) stays under Rs. 12 lakh, the Section 87A rebate can wipe this out to nil regardless of which row you’re in. Since deemed-STCG on debt funds is slab-rate income, not special-rate income, it qualifies for the rebate.

That’s genuinely good news for smaller investors: someone in the 5% or 10% bracket, comfortably under the Rs. 12 lakh threshold, may end up paying close to nothing on this gain even with indexation gone.

It’s really the investor sitting in the 20-30% brackets, above the rebate threshold, who feels the post-2023 change most.

Has Anything Changed In Budget 2025 or Budget 2026?

No, it has remained the same.

AMFI has been asking for it.

In its Budget 2025 submission, AMFI requested that debt fund LTCG be aligned with listed bonds at a flat 12.5% after just one year of holding, regardless of purchase date. That request wasn’t accepted.

Budget 2026 retained the existing structure without further change to debt fund taxation.

Frequently Asked Questions

Q: Are indexation benefits removed for debt mutual funds?

A: Yes, completely, for both categories now. Units bought on or after 1 April 2023 never had indexation. Units bought before that date lost indexation too, if sold on or after 23 July 2024.

Q: How are debt mutual funds taxed in India right now?

A: It depends entirely on your purchase date. Post-April 2023 purchases: slab rate, always. Pre-April 2023 purchases: 12.5% flat if held over 24 months and sold after July 2024, otherwise slab rate.

Q: Is LTCG on debt mutual funds still a thing?

A: Only for units bought before 1 April 2023 and held over 24 months. For anything bought after, there’s no LTCG category left — everything is deemed short-term.

Q: What is STCG on debt mutual funds?

A: Short-term capital gains on debt funds are taxed at your income tax slab rate — same as it’s always been, and now the default treatment for most debt fund holdings going forward.

Conclusion

Check your debt fund’s purchase date before you check anything else. This is the main takeaway of this article.

The old advice of “hold for three years to get LTCG benefit” no longer applies uniformly. It depends on when you bought in, and even then, the benefit today is a flat 12.5% without indexation.

Debt mutual funds today sit almost exactly where bank FDs do, tax-wise, for anything bought after April 2023.

The case for holding them still exists:

• Better liquidity,
• Loss set-off flexibility,
• No TDS on redemption, the way FDs get taxed on accrued interest

But the tax-arbitrage argument that used to be the headline reason to prefer them is largely gone.

Have a happy investing.
