Marginal Slab Rate
Also written MSR · Marginal Slab Rate (MSR)
The investor's own applicable income-tax slab rate. It taxes IDCW, short-term gains on most non-equity schemes, and all gains on debt-oriented funds and debt ETFs.
In plain language
Some mutual fund income is taxed at a fixed rate written into the law — the same for everyone. The rest is simply added to the investor's income and taxed at whatever rate that investor pays.
The workbook's Chapter 8 tax table calls that second rate the Marginal Slab Rate (MSR): the rate of tax applicable to the investor based on their total income for the year.
The practical consequence is that the same gain can cost two investors very different amounts of tax — one in a low slab, one in a high slab.
How it works
Where MSR applies — the Chapter 8 table.
| Investment | STCG | LTCG | Long-term after |
|---|---|---|---|
| Equity-oriented funds (incl. hybrids with more than 65% equity) | 20% | 12.50%, first Rs 1.25 lakh a year exempt | 12 months |
| Debt-oriented funds (incl. hybrids with more than 65% debt) | MSR | MSR | — |
| Hybrid funds with 35%–65% domestic equity | MSR | 12.50% | 24 months |
| Other MFs (Fund of Funds, International Funds / FoFs) | MSR | 12.50% | 24 months |
| Equity ETFs | MSR | 12.50% | 12 months |
| Gold ETFs | MSR | 12.50% | 12 months |
| Debt ETFs | MSR | MSR | — |
IDCW too. Since the February 2020 Budget, a distribution is added to the taxable income of the investor and taxed at the applicable rate — the tax rate goes up for those with higher income, and investors in tax-exempt categories pay nothing.
Dates that decide the table. Investments made before 1 April 2023 keep the old structure, and units redeemed before 23 July 2024 are taxed at the old rates.
An inconsistency to note. The table puts Equity ETFs at MSR for short-term gains, while equity-oriented funds get 20 percent. By Chapter 8's own definition — more than 65 percent in equity shares listed in India — an equity ETF would ordinarily be equity-oriented. Answer table-based questions from the table, but be aware the two statements do not sit comfortably together.
A worked example
Priya is in a 30 percent slab (illustrative; cess and surcharge ignored). She makes a gain of Rs 80,000 in each of four situations.
| Scheme and holding period | Rate that applies | Tax |
|---|---|---|
| Debt fund, held 30 months | MSR (no long-term rate for debt-oriented funds) | Rs 24,000 |
| International FoF, held 14 months | MSR — short-term, because this category needs 24 months | Rs 24,000 |
| Hybrid fund with 50% equity, held 30 months | Long-term, 12.50% | Rs 10,000 |
| Equity-oriented fund, held 8 months | Short-term, 20% | Rs 16,000 |
Now give the debt fund gain to her father, whose income falls in a 5 percent slab (illustrative): Rs 4,000. Same scheme, same gain, same holding period — the MSR is what differs.
And an IDCW of Rs 10,000 from any of these schemes is taxed at Rs 3,000 for Priya but Rs 500 for her father.
Why NISM asks about it
Chapter 8.2 (Capital Gains) presents the tax table in which MSR appears, and 8.3 applies the slab rate to IDCW. Expect a table question — debt-oriented funds are taxed at MSR on both short- and long-term gains, and FoFs and international funds need 24 months to become long-term — and the conceptual question on why the 2020 change made IDCW costlier for high-income investors.
Common exam traps
- Debt-oriented funds and debt ETFs: MSR for all gains, with no long-term concessional rate.
- Equity-oriented funds are the exception to MSR on short-term gains — 20 percent.
- Fund of Funds and international funds need 24 months, not 12, to be long-term.
- A FoF investing in equity funds is non-equity-oriented for income tax, so MSR applies to its short-term gains.
- IDCW is taxed at MSR since the 2020 Budget; dividend distribution tax no longer applies.
- The Rs 1.25 lakh LTCG exemption is only for equity shares and equity-oriented funds.

Related terms
- Fund of fundsAn AIF that invests in the units of other AIFs rather than directly in investee companies — buying diversification across managers and strategies, and paying two layers of fees for it.
- IDCWThe renamed dividend option of a mutual fund scheme — a payout that is part income and part return of your own capital, which is why the NAV falls by exactly the amount distributed.
- Deferment of taxesThe advantage of the growth option: scheme income is tax-exempt and capital gains are taxed only when units are sold, so returns compound for years before any tax is paid.
- Equity-oriented fundA fund that puts at least 65% of its proceeds into listed domestic equity shares — the tax definition that unlocks the 12.5% long-term rate and the Rs 1,25,000 annual exemption.
- Long Term Capital GainThe gain on mutual fund units sold after the long-term holding period — 12 months for equity-oriented funds, 24 months for most others — taxed at 12.5% on equity funds above a Rs 1.25 lakh yearly exemption.
- Short Term Capital GainThe gain on mutual fund units sold within the holding period — 12 months or less for equity-oriented funds, 24 months or less for most others — taxed at 20% for equity funds and at slab rate otherwise.
- TDS on IDCWTax deducted at source at 10 percent on an IDCW from a mutual fund scheme above Rs 5,000 — applicable even to resident investors, unlike redemption proceeds, which carry no TDS for residents.
- Dividend Distribution TaxThe tax a mutual fund scheme itself deducted before paying a dividend, abolished from April 2020 — since when the payout has instead been taxed in the investor's own hands at their slab rate.
- Corporate Bond FundAn open-ended debt scheme that must invest at least 80 percent of total assets in corporate bonds rated AA+ and above — the higher-quality counterpart to the credit risk fund.
