Deeply discounted security (DDS) meaning

In practice, a deeply discounted security is a bond or similar security issued at a large discount so that the amount received on redemption substantially exceeds the amount paid on issue. For UK tax purposes (see HMRC SAIM3020), a security is a “deeply discounted security” (DDS) if the amount payable on maturity, or any other redemption, will or may exceed the issue price by more than 0.5% for each complete year in the redemption period, capped at 30 years. Key features and significance: - Typical examples include zero‑coupon bonds, payment‑in‑kind (PIK) notes and other low‑coupon or discount bonds. - The return represented by the discount/redemption premium is generally charged to income (rather than as a capital gain), with potential charges on redemption or earlier disposal. - Specific statutory computation rules and exemptions may apply; practitioners should verify the applicable regime for the instrument’s terms. The UK statutory definition applies consistently in England & Wales, Scotland and Northern Ireland. In Ireland, “deeply discounted security” is not used as a defined legislative term in the same way; similar instruments are taxed under Irish rules on interest and discounts, so usage is descriptive and the precise treatment depends on the Taxes Consolidation Act provisions and instrument terms.
