If I am holding SGB purchased from secondary market which has already passed 5 years from the issue date, how can I surrender it directly to the government?
If I am holding SGB purchased from secondary market within a year and it is surrendered to the government after 5/8 years from the issue date, how the tax will be calculated?
Gains from these cases are not taxable, as noted in the quicko link which @TheGouda posted. These two cases fall under “redemption” and hence the gains are not taxable.
To understand the taxability of SGB, the source from where you bought the SGB is not relevant. So the taxability of gains from SGB will depend on where you sell/redeem these bonds.
Once an SGB completes 5 years from its issue date, the RBI opens a buy-back window (pre-mature redemption) where you can redeem it.
If you hold it till 8 years, RBI automatically redeems it on maturity.
In both cases—whether you redeem after 5 years or 8 years—the gains are completely tax-free (exempt from income tax).
Lastly, it will be taxed as capital gains only if you sell it in the secondary market.
