Fixed Deposit vs Debt Mutual Fund: Which Wins After Tax?
Post-Budget 2024 reality: when an FD actually beats a debt fund — and when it doesn't.
Before April 2023, debt mutual funds beat FDs handily because of indexation. That edge is gone. Today the comparison depends almost entirely on your tax slab and time horizon.
Tax Treatment Side-by-Side
| Feature | FD | Debt MF (post Apr-2023) |
|---|---|---|
| Return type | Fixed | Market-linked |
| Tax | Slab rate (interest) | Slab rate (gains) |
| When taxed | Every year (accrual) | Only on redemption |
| TDS | 10% above ₹40k | Nil for residents |
| Liquidity | Premature: 0.5-1% penalty | 1-3 days, no penalty |
When FD Wins

Frequently Asked Questions
Did Budget 2024 reintroduce indexation on debt funds?
No. Debt fund indexation is gone for units bought on or after 1 April 2023. Only units bought before that date retain LTCG with indexation if held > 36 months.
Are arbitrage funds debt or equity?
Arbitrage funds are taxed as equity (12.5% LTCG above ₹1.25 lakh). For 30% slab investors needing 1-3 year horizon, they often beat both FDs and debt funds after tax.
Is FD interest fully taxable?
Yes. FD interest is added to your income and taxed at slab rate. Senior citizens get ₹50,000 deduction under 80TTB; others get ₹10,000 under 80TTA only on savings account interest.
