Bonds vs Debt Funds After the Tax Change: The 2026 Decision Framework
Until 2023, this debate had a lazy answer: “debt funds, for the indexation.” Then the Finance Act 2023 removed indexation from debt funds — all gains on units bought since April 2023 are taxed at your slab, regardless of holding period — and the lazy answer died. What’s left is a genuine decision with real trade-offs.
The tax scoreboard, post-change
| Return type | Direct listed bond | Debt fund |
|---|---|---|
| Interest/accrual | Slab, taxed yearly as received | Slab, but deferred until you redeem |
| Capital gain | 12.5% + cess if listed & held >12m | Slab, always |
Two asymmetries now drive everything:
- Direct bonds kept an LTCG rate; funds lost theirs. A listed bond bought below par converts part of its return into 12.5% capital gains — a high-slab investor’s best remaining fixed-income tax break. Funds can never do this.
- Funds kept deferral; bonds never had it. A growth-option fund compounds pre-tax until redemption — over 10+ years, deferral claws back real value, and SWP withdrawals are taxed only on their gain portion.
Rule of thumb: short-to-medium horizons and high slabs favour direct bonds; very long horizons and “I’ll never look at this” money favour funds. Anyone in between should run their actual numbers through the FD vs bond calculator (works for fund YTMs too — enter the portfolio YTM minus expense ratio as a par bond).
The non-tax scoreboard
Direct bonds win on:
- A known rupee amount on a known date. No NAV between you and maturity — the entire case for goal-dated money.
- Zero fees for sovereigns via RBI Retail Direct.
- Choice of exact credit. You hold precisely the risks you chose — nothing the fund manager bought last quarter.
Funds win on:
- Diversification per rupee. ₹5,000 in a corporate bond fund holds 50+ issuers; ₹5,000 in direct bonds holds a fraction of one. For sub-AAA credit, this is decisive — retail-sized direct portfolios can’t diversify credit properly, which is why the checklist caps issuers at 5%.
- Liquidity. T+1 redemption at NAV beats thin exchange volumes every time.
- Zero admin. No auctions, no coupon sweeping, no accrued-interest reconciliation.
And one fund-specific risk bonds don’t have: other investors. Franklin 2020 proved a debt fund’s liquidity promise depends on unit-holders not all asking at once. Rare, structural, worth knowing.
The decision grid
| Your situation | Better vehicle |
|---|---|
| Goal with a date (fees 2029, house 2031) | Direct sovereign bonds/ladder |
| 30% slab, 2–5 yr horizon | Direct discount bonds (LTCG edge) |
| Want corporate yield without underwriting credit | Corporate bond fund / Bharat Bond TMF |
| 10+ year compounding, no income needs | Growth-option fund (deferral) |
| Monthly liquidity uncertainty | Fund (or T-bill ladder) |
| Below-AA yield hunting | Fund, if at all — diversification is survival |
| Maximum simplicity | Fund, honestly |
The hybrid most people should run
The debate presents a false binary. The clean architecture:
- Sovereign core, held direct: G-secs/SDLs/T-bills via Retail Direct — free, exact, tax-smart when bought at discounts.
- Credit sleeve, held via funds/TMFs: if you want corporate spread, let a diversified vehicle carry the default risk.
- Cash layer: liquid fund + T-bill ladder.
That uses each structure precisely where its advantages bind — and it’s simpler to run than either purist version.
FAQ
Do target-maturity funds change this? They’re the middle path — fund diversification with an approximate maturity date. Full treatment here.
What about the old pre-2023 fund units? Units bought before April 2023 retain grandfathered treatment on past rules for gains — check with a CA; this guide addresses money invested today.
Is TDS different? Funds deduct no TDS on growth (nothing is paid out); listed bond interest has the ₹10,000 TDS threshold. A cashflow difference, not a tax difference.
