US treasury tax treatment

Hi Admin, Thank you very much for your help in advance. As I am a UK resident but nor UK domicile, do NOT use remittance basis. Could I confirm the tax arrangement in US treasury bond in my OFFSHORE account please ? a) buy and hold till maturity, the difference between what i paid for the bond and what you redeem it is FOREIGN income tax? should be reported in SA106 or SA101? b) buy and sell before maturity, the difference between what i paid for the bond and what you sell it is capital gain tax in SA108? c) coupon/interest from treasury is treated as income tax in SA106 or SA101? d) when preparing accrual interest income, should I put as a accrual interest gain and loss or should I make it as the net amount of income ? Thanks and regards ,
