CFDs and Spread bets are different products and are treated differently for tax purposes. While they are both geared products CFDs attract commission charges, financing charges for long positions, are opened ended and gains are taxable. Whether or not CFD profits are liable to CGT or income tax will depend on individual circumstances - someone investing for the medium to longterm using CFDs could reasonably expect those gains / losses to come under the CGT umbrella whereas a short term trader, and frequent trader, using CFDs, could expect his gains to be subject to income tax.
