you should only pay that if u r drawing that as a wage, the only way u cant pay that amount in tax is not to draw 38 grand, (its 40 on anything over 38 grand 22 up to 38 grand)
it all depends on how u r running ur business, and i take it from the size of urs ur are not a sole trade but a ltd proper business and drawing a wage, u coudl split ur wage between u and ur wife if she int working, to help cut down on the tax
