A one year bond matures in Oct 08 are all the profit set against the tax year 08-09 or can it be split 50/50 with the tax year 07/08 as the bond gained interest for 6months in each tax year.
As a general tax is payable according to when you receive the money, not when it was accrued.
Sometimes the taxman will make an exception - but the only example I can think of is when interest is payable on 6 April because the day it was due (5th) was a Sunday or holiday
