FD vs Debt Fund vs Liquid Fund After Tax: Which Wins in 2026?
For years, debt mutual funds had one big advantage over fixed deposits: indexation. Hold for three years and you paid much less tax. That ended on 1 April 2023. Debt fund gains are now taxed at your slab rate, just like FD interest. So is there still any reason to choose a debt fund?
I compared FD vs debt fund vs liquid fund after tax in two ways: a clean model with the same return for each, and real numbers using current FD rates and the actual returns of every liquid, money market, short duration, corporate bond and arbitrage fund in India.
Quick answer
- Debt and liquid funds bought since April 2023 are taxed at your slab rate, like FDs. The old indexation benefit is gone.
- At the same 7% return, a debt fund still edges out an FD because you pay tax only when you sell, not every year: ₹12.77 lakh vs ₹12.65 lakh on ₹10 lakh over 5 years in the 30% slab. The gap is small.
- For the 30% slab, arbitrage funds were the clear winner on tax: ₹13.66 lakh after 5 years, because they're taxed like equity at 12.5%.
- Real returns to August 2026: liquid funds 6.4% over 1 year, short duration 7.3% a year over 3 years, arbitrage 6.4%. Big-bank FDs pay about 6.3–6.6% for 1–2 years.
- If you pay no tax or are in a low slab, FDs (and small-finance-bank or post office deposits paying 7–7.5%) are often the simplest good choice.

FD vs debt fund vs liquid fund: the tax rules in 2026
Here are the current rules for each option, FY 2026-27. They apply to debt and liquid fund units bought on or after 1 April 2023.
| Bank FD | Debt or liquid fund | Arbitrage fund | |
|---|---|---|---|
| How returns are taxed | Interest added to income, taxed at your slab | Gains taxed at your slab | Equity rules: 20% if sold within 12 months; 12.5% after that |
| When you pay | Every year, as interest accrues, even if you don't withdraw | Only when you sell | Only when you sell |
| Tax-free allowance | None (basic exemption only) | None (basic exemption only) | First ₹1.25 lakh of long-term equity gains a year |
| TDS | 10% if interest from one bank exceeds ₹50,000 a year (₹1 lakh for seniors) | None for residents | None for residents |
| Safety | Insured up to ₹5 lakh per bank per depositor (DICGC) | Not insured; small credit and interest-rate risk | Not insured; low risk but returns vary month to month |
| Getting money out | Penalty of about 0.5–1% for breaking early | Liquid: next day, tiny exit load in first 7 days | Usually 2–3 days; exit load if sold within a month |
The key difference is timing. FD interest is taxed every year, even if it stays in the FD. Debt fund gains are taxed only when you sell. Arbitrage funds are the odd one out: they hold shares and futures in a hedged way, so the law treats them as equity funds.
After-tax returns at the same 7%
To see the pure tax effect, assume every option earns exactly 7% a year before tax. Here's what ₹10 lakh becomes after five years and after tax.
| Your tax slab | Bank FD | Debt or liquid fund | Arbitrage fund | Best option |
|---|---|---|---|---|
| No tax / 0% slab | ₹14.03 lakh | ₹14.03 lakh | ₹13.66 lakh | Debt fund |
| 10% slab | ₹13.55 lakh | ₹13.61 lakh | ₹13.66 lakh | Arbitrage |
| 20% slab | ₹13.10 lakh | ₹13.19 lakh | ₹13.66 lakh | Arbitrage |
| 30% slab | ₹12.65 lakh | ₹12.77 lakh | ₹13.66 lakh | Arbitrage |
₹10 lakh for 5 years at 7% a year before tax, 30% slab plus 4% cess. FD tax paid yearly; fund tax paid on redemption. Arbitrage LTCG assumes the ₹1.25 lakh exemption isn't used elsewhere.
In the 30% slab, deferral gives the debt fund only a small edge over the FD, about ₹11,818 on ₹10 lakh over five years. In lower slabs the gap is smaller still. Real FDs also compound quarterly, which adds about 0.1–0.2% a year and can cancel the debt fund's edge entirely.
The arbitrage fund is the real outlier. At 12.5% tax with the first ₹1.25 lakh of gains tax-free, it kept ₹1.01 lakh more than the FD for someone in the 30% slab.
What debt and liquid funds actually returned
Models assume equal returns. Here is what each type of fund actually delivered, using the median direct plan in each category.
| Category (direct plans) | Funds | 1 year | 3 years | 5 years | Tax |
|---|---|---|---|---|---|
| Overnight funds | 21 | 5.20% | 6.06% | 5.69% | Slab rate |
| Liquid funds | 24 | 6.35% | 6.91% | 6.30% | Slab rate |
| Money market funds | 15 | 6.42% | 7.28% | 6.58% | Slab rate |
| Arbitrage funds | 21 | 6.38% | 7.28% | 6.69% | Equity rates |
| Short duration funds | 43 | 6.27% | 7.30% | 6.49% | Slab rate |
| Corporate bond funds | 12 | 5.24% | 7.26% | 6.18% | Slab rate |

Liquid and money market funds returned about 6.4%–6.4% over the last year, close to what large banks pay on one-year FDs. Short duration and corporate bond funds did better over three years, about 7.3% a year, as interest rates fell in 2025 and bond prices rose. That reversed recently: the RBI raised the repo rate to 5.50% in October 2026, which pushes bond prices down. Corporate bond funds' one-year return fell to 5.2%.
₹10 lakh for 3 years in the 30% slab. FD at 6.45% compounded quarterly; funds at their category's median 3-year return to August 2026.
With real numbers, the 30% slab investor did best in arbitrage and short duration funds. But those past returns aren't guaranteed, while the FD rate is.
Which one to choose for each goal
- Emergency fund (need it any day): a liquid fund or a sweep-in FD. Liquid funds pay out the next working day and have no penalty after 7 days.
- Money for 1–3 years, low or no tax slab: a bank FD is simple and insured up to ₹5 lakh per bank. Small finance banks and the post office pay more (about 7–7.5%), with the same insurance on bank deposits.
- Money for 1–3 years, 30% slab: consider an arbitrage fund. Its tax rate is 20% even under a year, and 12.5% after that.
- Money for 3+ years: a short duration or corporate bond fund can add a little return, with some ups and downs when rates move. Stick to high-quality, low-cost funds in direct plans.
- Money for 7+ years: look at equity instead. See how often the Nifty lost money by holding period.
Risks and fine print
- Debt funds aren't risk-free. In 2020, six Franklin Templeton debt schemes were wound up after credit troubles; investors waited years for full payment. Prefer funds that hold government and top-rated bonds.
- Rates change. FD rates are fixed for the term; fund returns move with interest rates. After the October 2026 rate hike, new FDs may pay more.
- The 2023 rule has a cut-off. Debt fund units bought before 1 April 2023 still follow older rules: 12.5% without indexation if held over 24 months.
- Always use direct plans. In low-return categories, a 0.5% commission is a large share of what you earn. See Direct vs regular mutual funds.
Frequently asked questions
Is a debt fund better than an FD after the 2023 tax change?
Only slightly, for most people. Both are taxed at your slab rate. Debt funds defer the tax until you sell, which was worth about ₹11,818 on ₹10 lakh over 5 years in the 30% slab at a 7% return.
How are liquid funds taxed in India?
Liquid fund units bought on or after 1 April 2023 are taxed at your income tax slab rate when you sell, regardless of how long you hold them.
Are arbitrage funds better than FDs for high-tax investors?
On tax, yes. They're taxed like equity: 20% within 12 months and 12.5% above ₹1.25 lakh after that. At a 7% return, ₹10 lakh grew to ₹13.66 lakh over 5 years versus ₹12.65 lakh in an FD for a 30% slab investor.
Is FD interest taxable every year even if I don't withdraw it?
Yes. FD interest is taxable as it accrues each year, and banks deduct 10% TDS if your interest from one bank exceeds ₹50,000 a year (₹1 lakh for senior citizens).
What is the return of liquid funds in 2026?
The median liquid fund (direct plan) returned 6.35% in the year to August 2026 and 6.91% a year over three years.
