How Sovereign Gold Bonds (SGB) Work: 2.5% Coupon Formula, Gold Appreciation & Section 47(viic) Exemption
Sovereign Gold Bonds (SGB) are government securities denominated in grams of fine gold issued by the Reserve Bank of India on behalf of the Government of India. SGB eliminates the risks and expenses of holding physical gold, paying a guaranteed 2.50% annual coupon interest while granting complete 100% capital gains tax exemption upon maturity under Section 47(viic) of the Income Tax Act.
Mathematical Derivation & Variable Explanations: Sovereign Gold Bonds (SGB) are government securities denominated in grams of gold issued by the Reserve Bank of India, providing capital appreciation alongside a guaranteed coupon yield.
- Dual Cashflow Generation Architecture: Total financial realization combines gold spot appreciation with semi-annual interest coupon:
$$\text{Total Return} = \left( P_{\text{redemption}} - P_{\text{issue}} \right) + \sum_{t=1}^{16} \left( P_{\text{issue}} \times \frac{0.025}{2} \right)$$The 2.50% annual coupon paid semi-annually delivers a guaranteed 20% cash distribution over the 8-year holding tenure ($16 \text{ payments} \times 1.25\%$).
- Section 47(viic) 100% Tax-Free Capital Gains: Under Section 47(viic) of the Income Tax Act 1961, redemption of SGBs at maturity (8 years) or during official RBI redemption windows (years 5, 6, 7) by an individual is 100% exempt from capital gains tax. Physical gold and Gold ETFs do not enjoy this exemption.
- Friction Elimination Advantage: Physical jewelry incurs 10%–25% unrecoverable making charges, 3% GST, and 5%–10% melting loss upon resale. SGBs eliminate all storage, making, and insurance costs, tracking pure 999 purity gold prices.
- Tax on Coupon: Semi-annual interest payments are taxable under 'Income from Other Sources' at individual slab rates without TDS.
- Secondary Market Trading & Demat Liquidity: SGB tranches trade on the National Stock Exchange (NSE) and Bombay Stock Exchange (BSE) in the secondary market under cash segments. Investors can buy existing tranches often trading at a 1%–4% discount to current spot gold prices. However, while capital gains upon sovereign redemption through RBI at maturity (8 years) or early redemption windows (years 5, 6, 7) are 100% tax-free under Section 47(viic), secondary market transfers before redemption are subject to LTCG tax at 12.5% if held for more than 12 months.
- Inheritance & Estate Planning Dynamics: Sovereign Gold Bonds can be held in single, joint, or minor names with parents as guardians. In the event of inheritance or succession, transfer of SGBs to legal heirs does not attract any capital gains tax or gift tax under Section 56(2)(x), maintaining full sovereign gold value and future tax-free redemption eligibility.
