For tax year 2011-12 18% applies to the capital gain element which falls between the individual's taxable income and £35,000. Above £35,000 the 28% applies.
If you earn £40,000 your taxable income is 40,000 less 7,475 ie 32,525.
Thus any capital gain will be taxed at 18% on the first 2,475 and 28% on the balance.
