What it is

Floating Rate Savings Bonds, 2020 (Taxable) are Government of India bonds available to eligible investors. RBI states that the bonds are interest-bearing, non-tradeable and repayable after seven years. The coupon resets half-yearly and is linked to the prevailing NSC rate plus a spread.

What can go wrong

  • The main practical risk is liquidity: the bond is non-tradeable and the money is locked for a long period, subject to specified premature-redemption rules.
  • Because the coupon floats, future income can move up or down when the reference rate changes.
  • Inflation can reduce the real purchasing power of fixed-income cash flows.

Tax in India

  • Interest is explicitly taxable and is generally included in normal taxable income at the investor’s applicable rate.
  • TDS can apply under the prevailing rules; final tax depends on the investor’s total income.
  • Because the bond is generally redeemed at par and not traded, the primary tax issue for most retail investors is taxation of periodic interest.

What the example below measures

The example below focuses on the tax increase caused by this instrument’s return for people starting with ₹6 lakh, ₹12 lakh or ₹50 lakh of normal taxable income. It does not treat TDS as final tax.

FRSB tax: what happens to a ₹6L, ₹12L or ₹50L income person?

This is an instrument-specific illustration, not the same generic tax chart repeated on every page.

FY 2026-27 · Default new regime
Example used on this page: Assume ₹5,00,000 in Floating Rate Savings Bonds and use 8.0% only as an illustration → ₹40,000 annual interest. The actual coupon resets and must be checked for the relevant half-year. Existing income below means normal taxable income before this investment return is added. Assumes a resident individual, no special-rate income, and includes 4% Health & Education Cess.
Existing taxable income before FRSB return

₹6,00,000

After adding return: ₹6,40,000
Increase in annual tax: ≈ ₹0

Income becomes ₹6,40,000. Because normal-rate total income is still within ₹12 lakh, the available resident-individual rebate can keep final tax at nil in this simplified example.

Existing taxable income before FRSB return

₹12,00,000

After adding return: ₹12,40,000
Increase in annual tax: ≈ ₹41,600

Income becomes ₹12,40,000. ₹12 lakh is exactly the rebate cut-off. Marginal relief limits the sudden tax jump; 4% cess is then added. This is a threshold effect, not a normal 104% tax rate.

Existing taxable income before FRSB return

₹50,00,000

After adding return: ₹50,40,000
Increase in annual tax: ≈ ₹41,600

Income becomes ₹50,40,000. ₹50 lakh is exactly the surcharge threshold. Marginal relief reduces the surcharge jump just above ₹50 lakh; 4% cess is then added.

Why the ₹12L and ₹50L examples can look surprising: both people start exactly on a tax boundary before the FRSB return is added. At ₹12 lakh, the 87A rebate boundary is crossed; at ₹50 lakh, the surcharge boundary is crossed. Marginal relief softens each jump, but 4% cess still applies. A person whose total income is comfortably inside a slab will normally see a much more familiar marginal tax effect. These cards are designed around your exact “₹6L / ₹12L / ₹50L income person then invests” question.
FRSB 2020 is explicitly a taxable Government of India savings bond. The coupon resets periodically; use the actual notified coupon for a real investment decision rather than the illustrative 8.0% used here.

Tax & bond words — explained simply

No jargon without meaning. These are the terms used on this FRSB page.

Floating rateAn interest rate that resets periodically instead of staying fixed for the entire tenure.
ResetThe date/period when the coupon is recalculated using the scheme’s reference formula.
CouponThe interest paid by the bond. FRSB interest is taxable.
Non-tradeableThese bonds are not normally bought and sold on an exchange; liquidity is mainly governed by the scheme’s redemption rules.
TDSTax Deducted at Source. Interest on taxable securities can be subject to TDS under the applicable rule; the deducted amount is a tax credit.
CessA 4% Health & Education Cess charged on income tax plus surcharge, if any.
