Debt Funds vs Fixed Deposits After the 2023 Tax Change: Which Wins Now?
The old tax edge of debt funds over fixed deposits is gone. A smaller advantage remains, tax deferral and flexibility, and so do some extra risks. Here is how they compare now, with numbers.

Key takeaways
- Debt mutual fund units bought on or after 1 April 2023 are taxed at your slab rate whenever you sell, the same rate as FD interest.
- The remaining tax advantage is timing: FD interest is taxed every year as it accrues, while fund gains are taxed only when you redeem. Over 5 years at 7%, this is worth about ₹10,000 to ₹15,000 per ₹10 lakh for a 30% taxpayer, before fund expenses.
- Bank FDs are insured by DICGC up to ₹5 lakh per depositor per bank. Debt funds have no insurance and carry interest-rate and credit risk.
- Liquid and overnight funds remain useful for emergency funds and parking money; target-maturity index funds suit known future dates.
- For people in low tax slabs, and for amounts within the insurance limit, simple FDs are often the cleaner choice.
For years, debt mutual funds had a clear tax advantage over fixed deposits. Held for more than three years, their gains were taxed at 20% after indexation, often an effective rate in single digits, while FD interest was taxed at the full slab rate. That advantage ended for new investments on 1 April 2023. Gains on debt fund units bought since then are taxed at your slab rate, exactly like interest.
So is there any reason to choose a debt fund over an FD now? There is, but the case is narrower than it was, and it comes with risks that FDs do not have.
How each is taxed now
| Bank fixed deposit | Debt mutual fund (bought after 31 March 2023) | |
|---|---|---|
| Tax rate | Your slab rate | Your slab rate |
| When tax is due | Every year, on interest accrued (even in a cumulative FD) | Only when you redeem |
| TDS | Above ₹50,000 interest a year per bank (₹1 lakh for seniors) | None for resident individuals |
| Costs | None (premature withdrawal penalty may apply) | Expense ratio, typically 0.1% to 0.5% a year in direct plans |
| Safety | DICGC insurance up to ₹5 lakh per depositor per bank | No insurance; interest-rate and credit risk |
| Liquidity | Locked for the term unless broken with a penalty | Redeem any business day; liquid funds pay in one day |
The deferral advantage, in numbers
Even with the same tax rate, a debt fund lets your full return compound until you sell, while an FD loses a slice to tax every year. Here is ₹10 lakh for five years, with both earning 7% before tax and a 30% taxpayer:
- Cumulative FD, tax paid yearly on accrued interest: grows to ₹12,65,138.
- Debt fund, earning 7% and taxed once at the end: ₹14,02,552 before tax, ₹12,76,956 after tax.
The deferral is worth ₹11,818 over five years, about 0.24% of the amount a year. It is real but modest, and the fund's expense ratio eats into it. With a realistic 0.25% expense ratio, the comparison across tax slabs looks like this:
| Tax slab | FD after 5 years | Debt fund after 5 years | Fund minus FD |
|---|---|---|---|
| Nil (income below taxable limit) | ₹14,02,552 | ₹13,86,243 | −₹16,309 |
| 5% | ₹13,78,857 | ₹13,66,159 | −₹12,698 |
| 20% | ₹13,09,688 | ₹13,05,905 | −₹3,783 |
| 30% | ₹12,65,138 | ₹12,65,735 | +₹597 |
For people in the 30% slab, the fund's deferral can more than offset its expense ratio. For people in low slabs, the FD usually comes out ahead, because there is little tax to defer and the expense ratio becomes the main difference.
Risks a fixed deposit does not have
Interest-rate risk
Bond prices move opposite to interest rates. A fund holding bonds with an average remaining life (duration) of 5 years would lose roughly 5% in value if market interest rates rose by 1 percentage point, and gain if they fell. Overnight and liquid funds have durations of days or weeks, so this risk is tiny; gilt and long-duration funds can swing several percent in a year.
Credit risk
If a company whose bonds the fund holds defaults, the fund can lose part of that money. Between 2018 and 2020 several defaults hit Indian debt funds, and some schemes were wound up. SEBI's risk-o-meter and the Potential Risk Class (PRC) matrix printed on each scheme show its interest-rate and credit risk; for core savings, prefer funds that hold government securities and highly rated public-sector bonds.
Where debt funds still make sense
- Liquid and overnight funds for parking money, including part of an emergency fund. They are redeemable in one business day, with very low risk. See our emergency fund guide.
- Target-maturity index funds, which hold government or PSU bonds maturing in a specific year. Held to maturity, their return is fairly predictable, much like a tax-deferred FD with daily liquidity.
- Large amounts beyond insurance limits, for people in high tax slabs who want flexibility and deferral, using low-risk categories.
- Rebalancing between equity and debt within the mutual fund system is convenient, though every switch is a taxable redemption.
Where fixed deposits are the better choice
- Low or nil tax slab, including many retirees and young earners: there is little or no tax to defer.
- Amounts within ₹5 lakh per bank, where deposit insurance gives near-certainty.
- Senior citizens, who receive higher FD rates and can use the Senior Citizens Savings Scheme (8.2% for October to December 2026).
- Anyone who wants zero price fluctuation and a fixed, known maturity amount.
For long-term safe money, PPF (7.1%, tax-free) and EPF and VPF contributions often beat both FDs and debt funds after tax. See ELSS vs PPF.
The bottom line
After 2023, the choice between a debt fund and an FD is no longer about tax rates. It is about timing of tax, flexibility and risk. High-slab investors with large balances can still benefit from low-risk debt funds; most others will do just as well with FDs, small savings schemes and PPF, which are simpler and safer.
Frequently asked questions
Is TDS deducted on debt fund redemptions?
For resident individuals, mutual funds do not deduct TDS on redemption gains; you pay the tax yourself through your return or advance tax. Banks deduct TDS on FD interest above the yearly threshold (₹50,000 per bank, ₹1 lakh for senior citizens) unless you submit Form 15G/15H where eligible.
What happened to debt funds bought before April 2023?
Units bought before 1 April 2023 and held for more than 24 months are taxed as long-term gains at 12.5% without indexation (since 23 July 2024). Held for 24 months or less, they are taxed at your slab rate.
Can a debt fund lose money?
Yes. If interest rates rise, the prices of the bonds a fund holds fall, especially in longer-duration funds. If a borrower defaults, the fund can lose part of that investment, as happened in several funds between 2018 and 2020. Overnight and liquid funds have very low risk of this kind, but not zero.
Which is better for senior citizens?
Senior citizens often get 0.25% to 0.5% more on bank FDs and can use the Senior Citizens Savings Scheme (8.2% for October-December 2026). With a higher TDS threshold and often lower tax slabs, FDs and SCSS are usually the simpler choice.
