Deeply discount bond

When a corporate was issued, the issue price was close to par and, hence, the bond is not a deeply discount bond. A year later, because of interest rate change, the bond market price is below par. If I buy this bond at the market price and hold to maturity, I will make a profit. Will this profit be subject to capital gain tax or income tax? As far as I understand, if the bond is not a deeply discount bond, the gain will be under CGT and not income tax. Will the bond status change from not being a deeply discount bond to a deeply discount bond simply because of the secondary market price?

Hi Eack,
Please have a look at the guidance at SAIM3020, to determine if your bonds are still considered deep discount securities.
