If you make £100 on futures trading then hedge your trade using a spreadbet. The futures trades goes to zero and the spreadbet goes to 100. Do you pay taxes at the end of the year?
Isn't the above method an easy way to offset tax liability at the end of the year? Saves having to setup a limited company and paying dividends. You could in affect offset all futures trading "losses" by taking a spreadbet "hedge" which happens to reduce your tax liability to zero?
