thanks for the reply...
I note that on the Form 12 a taxpayer is allowed to have 2 seperate trades. I didn;t understand why, but after reading Tax books online, mostly from England and Wales I'm thinking....
If I submit 2 sperate Form TR1s and divide my sole trader business into two, for example 1=Gardening 2=Handyman (these are just examples) then I could keep my income in each under 3174
However, the question is that 3174 figure per trade, or per taxpayer?
