LTCG · 12.5%
- Gain₹1,00,000
- Tax₹12,500
- + Cess (4%)₹500
- Net in hand₹5,87,000
Listed debt uses the 12-month test: 12.5% without indexation long-term, slab short-term. Interest is taxed at slab separately, every year.. The 4% health & education cess is included; surcharge is not modelled because it depends on your total income. Coupons are taxed at slab separately, every year. Confirm with a CA.
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.
