Then yes i am a higher rate tax payer
I will have to find a calculator out there that calculates the tax
As you're a high rate tax payer it'd probably be better to invest in an ISA then as, or only invest enough in the fixed savings account so you accrue no more than £500 interest.
1year fixed ISA is up at 5.2% now so it's not too shabby. As mentioned by others with both of these the amount invested must remain in the account until the end of the fixed year. If you need access to any money leave that in bonds.
