Debt vs Equity Funds After Tax: How SEBI's 16 Debt Categories Meet the Post-2023 Slab Rule

When an investor compares a debt mutual fund with an equity mutual fund today, the decision is no longer just about risk appetite. Since 1 April 2023, the tax code has quietly redrawn the map. Specified debt funds bought on or after that date lost the long-term capital gains concession they enjoyed for decades, while equity-oriented funds held beyond 12 months still pay a headline 12.5% under the Budget 2024 regime. This piece works through the post-tax arithmetic using SEBI's own 16-category debt framework and the current slab rules, so the number you keep — not the number the fund advertises — drives the choice.

The reference framework is SEBI circular SEBI/HO/IMD/DF3/CIR/P/2017/114 dated 6 October 2017, which standardised debt schemes into 16 distinct categories. Understanding those categories matters, because a liquid fund and a gilt fund carry very different interest-rate risk even though both are now taxed identically at your slab.

Side-by-Side Comparison

At the product level, a debt fund lends money (to governments, banks, PSUs or companies) while an equity fund buys shares. SEBI defines an equity-oriented fund as one holding at least 65% in domestic equities. The table below sets the two side by side on the features that decide post-tax return.

The 16 debt categories from the 2017 circular are: overnight, liquid, ultra short duration, low duration, money market, short duration, medium duration, medium-to-long duration, long duration, dynamic bond, corporate bond, credit risk, banking and PSU, gilt, gilt with 10-year constant duration, and floater. Each caps a different slice of the yield curve, but as of the Finance Act 2023 every one of them is taxed the same way for units bought on or after 1 April 2023: at the investor's slab rate.

Consider a worked example. An investor in the 30% slab (new regime, taxable income above Rs 24 lakh, per the FY 2025-26 slabs) puts Rs 10 lakh into a corporate bond fund returning 7.5% and holds it for three years. The fund grows to roughly Rs 12.42 lakh, a gain of about Rs 2.42 lakh. Because the units were bought after 1 April 2023, the entire gain is added to income and taxed at 30% plus 4% cess, an effective 31.2%, leaving a post-tax gain near Rs 1.66 lakh. The same Rs 10 lakh in an equity fund compounding at 11% over three years grows to about Rs 13.68 lakh, a gain of roughly Rs 3.68 lakh; after the Rs 1.25 lakh annual exemption and 12.5% LTCG on the balance, the tax is close to Rs 30,375, leaving a post-tax gain above Rs 3.37 lakh. You can model your own figures with the SIP calculator or the lump-sum calculator.

Tax Treatment

The heart of the debt-versus-equity question now sits in three rules that changed within 18 months of each other. First, the Finance Act 2023 inserted the specified-mutual-fund treatment: units of debt funds (funds with 35% or less in domestic equity) purchased on or after 1 April 2023 are deemed short-term regardless of holding period and taxed at slab rates, with no indexation. Second, Budget 2024, effective 23 July 2024, reset equity capital-gains rates. Third, the annual LTCG exemption for equity rose to Rs 1.25 lakh from the earlier Rs 1 lakh.

The table below captures the current position as published on incometax.gov.in and in the Budget 2024 memorandum.

Two nuances protect against costly mistakes. Debt-fund gains carry no indexation for units bought on or after 1 April 2023, so the old trick of inflating cost basis to shrink the taxable gain is gone. And the 4% health and education cess applies on top of every rate above; a 30%-slab investor therefore pays an effective 31.2% on debt-fund gains. For the equity investor, the 12.5% rate also attracts the 4% cess, taking the effective long-term rate to 13% on gains above the Rs 1.25 lakh threshold.

Surcharge is the final layer and here the regime choice matters. The maximum surcharge in the new tax regime is capped at 25%, even for income above Rs 5 crore, whereas the old regime still runs to 37% on ordinary income. For capital gains specifically, surcharge on both equity LTCG and STCG is capped at 15%. High earners drawing large slab-taxed debt gains should note that those gains feed the surcharge calculation on total income. Terms such as long-term capital gains and indexation are worth revisiting before filing.

For tax-planning within Section 80C, an equity-linked savings scheme sits in a different bracket again: it is taxed like any equity fund at exit but earns an upfront deduction. Our ELSS calculator shows the interaction, and the PPF calculator covers the exempt-exempt-exempt alternative for the debt-like portion of a portfolio.

Who Should Pick Which

Tax is one input; the goal and time horizon remain the primary drivers. The framework below maps investor profiles to the sensible default after the 2023 and 2024 changes.

The short-horizon saver (under 3 years). Someone parking an emergency fund or a house down-payment due in 18 months should still favour a liquid or ultra-short-duration debt fund from the SEBI list. Yes, the gain is taxed at slab, but a liquid fund's ~6.5% to 7% return with minimal volatility beats risking capital in equity over so short a window. The repo rate stood at 5.25% after the RBI MPC held it unchanged on 5 August 2026, its fourth consecutive pause, so short-tenor debt yields are steady rather than falling.

The tax-sensitive long-term compounder (7 years or more). For a retirement or child-education goal a decade away, equity's structural post-tax edge is now decisive. A 12.5% long-term rate with a Rs 1.25 lakh annual shield comfortably undercuts slab-rate taxation of debt for anyone in the 20% or 30% bracket. Systematic investment smooths entry; the earlier worked example showed roughly Rs 3.37 lakh kept on equity versus Rs 1.66 lakh on debt over three years for a 30%-slab investor.

The retiree seeking stability. Capital preservation outranks tax efficiency here. A retiree in the 5% or nil slab loses little to slab taxation on a debt fund, so the low volatility of a banking and PSU or short-duration fund is worth more than equity's headline post-tax advantage. Someone with taxable income up to Rs 12 lakh in the new regime pays zero tax after the Section 87A rebate, now Rs 60,000 for FY 2025-26, which can neutralise modest debt-fund gains entirely.

The high earner above Rs 5 crore. The new regime's 25% surcharge cap (versus 37% in the old regime) plus slab-rate debt taxation makes large debt allocations expensive; such investors typically tilt toward equity funds and arbitrage funds, the latter taxed as equity despite behaving like debt.

The Arbitrage Fund Wrinkle

One category deserves separate mention because it exploits the very rules above. An arbitrage fund holds 65%-plus in equity (satisfying the equity-oriented test) but hedges every position, so it behaves like a low-risk debt substitute while being taxed at 12.5% long-term and 20% short-term rather than at slab. For a 30%-slab investor needing a one-to-three-year parking place, an arbitrage fund returning even 6.5% can beat a debt fund returning 7.5% once tax is applied. This is legal category arbitrage sanctioned by SEBI's 65% equity threshold, and it has drawn large inflows since April 2023.

Reading Your Own Numbers

The single most useful habit after these changes is to compute post-tax, not pre-tax, return before committing. The formula is simple: post-tax return equals pre-tax return multiplied by one minus your effective tax rate on that gain. For a 30%-slab debt investor the effective rate is 31.2%; for the same investor in equity long-term it is 13% only on the slice above Rs 1.25 lakh. Run both through the SIP calculator with your own horizon before deciding.

FAQ

Are all debt mutual funds taxed at slab rate now?

Only units bought on or after 1 April 2023 in funds holding 35% or less in domestic equity. Units purchased before that date retain their earlier long-term treatment for gains, though Budget 2024 removed indexation for transfers on or after 23 July 2024. Always check your purchase date against incometax.gov.in guidance.

What is the LTCG exemption on equity funds for FY 2025-26?

The first Rs 1.25 lakh of long-term capital gains from equity-oriented funds is exempt each financial year, up from Rs 1 lakh earlier. Gains above that are taxed at 12.5% plus 4% cess, per the Budget 2024 memorandum.

Do debt funds still get indexation benefit?

No. For units bought on or after 1 April 2023 there is no indexation and no long-term concession; the gain is added to income and taxed at your slab. Indexation was also withdrawn for most other assets from 23 July 2024 under Budget 2024.

How many debt fund categories does SEBI recognise?

SEBI's 6 October 2017 circular (SEBI/HO/IMD/DF3/CIR/P/2017/114) defines 16 debt scheme categories, from overnight and liquid at the short end to long duration and gilt with 10-year constant duration at the long end. Each has defined duration or credit-quality limits.

Is an arbitrage fund taxed as debt or equity?

As equity. Because it maintains 65% or more in equity exposure (fully hedged), it qualifies as an equity-oriented fund and is taxed at 12.5% long-term and 20% short-term, not at slab rate, per amfiindia.com category definitions.

Which is better after tax for a 30% slab investor over 10 years?

For a decade-long horizon, an equity fund's 12.5% long-term rate with the Rs 1.25 lakh annual exemption almost always beats slab-rate debt taxation. Debt makes sense mainly for short horizons or for investors in the 5% or nil slab.

Does the Section 87A rebate cover mutual fund gains?

The rebate, now Rs 60,000 in the new regime for FY 2025-26, applies to total income up to Rs 12 lakh and can offset slab-rate debt-fund gains, but it does not apply to the special 12.5% or 20% equity capital-gains rates, which are charged separately.
