Its all so wrong. If it brings in a taxable income, then you should be able to claim it
Its a strange one, I was thinking maybe its down to the fact that the money earned is not guaranteed, but at the end of the
day you have still paid out which will mean you have less taxable income at the end of the tax year.
Maybe it falls under gambling, but then you could say the same about advertising/marketing which guarantees nothing for the
cost.
