What this calculator answers

A ₹1,00,000 gain on a listed corporate bond held 18 months is LTCG at 12.5% — about ₹12,500 of tax; the same gain on an unlisted bond is deemed short-term at your slab, about ₹30,000 at 30%. Enter the amounts, holding and listing to see the split.

How it is calculated

Listed paper held over 12 months is taxed at 12.5% without indexation; listed short-term and all unlisted gains (deemed short-term under section 50AA for transfers on/after 23 Jul 2024) are taxed at the slab rate you set.

Simplified: this estimator covers post-23-Jul-2024 listed and unlisted corporate-bond/debenture gains; government securities can have different treatment. It excludes surcharge and cess, and coupons (always slab-taxed) are not included. Verify with a CA — tax rules change.

Common questions

Why is my unlisted bond always short-term?

Section 50AA deems gains on unlisted bonds and debentures transferred, redeemed or matured on or after 23 Jul 2024 as short-term, whatever the holding period.

What happened to indexation?

Gone for bonds under the Finance (No. 2) Act 2024 regime: listed LTCG is 12.5% flat with no indexation from 23 Jul 2024.

Is the interest included?

No — coupons are taxed at slab every year regardless of listing. This estimator covers only the transfer/redemption gain.
