Hello and welcome to the site. Thank you for your question.
Based on information provided, you will be taxed on £23,274 at 20% and your income tax payable will be £4,654.
As you are self employed you would also pay National insurance contributions, both Class 2 and Class 4, as follows:
Class 2 rate for 2013/14 is £2.70 pw i.e £140.40 for full tax year
Class 4 rate for 2013/14 is - first £7,755 per year at 0%
(32,714-7,755) £24,959 at 9% £2,246
So maximum NI payable is (140.40+2,246) £2,386.40
Income tax payable £4,654.
