Paying Tax on Uk Treasury Bills

Hello, I've recently purchased some UK treasury bills and I understand that the income from this is taxed as it is a Deeply Discounted Security. I'm wondering how I declare this income and if tax is due on this amount. I'm a basic rate tax payer and the income from the bills will be under £25 this tax year. Do I declare this as missing income on my PAYE tax account or is there another way this needs to be declared? Thanks

Hi C,
If you invest in deeply discounted securities, put the difference between what you paid for the bond and what you redeem or sell it for in box 3 of SA101 (page Ai1).

Thank you.
