Is it taxable?
Yup, I’m afraid so. Whether you are being paid for your time and companionship, to give a massage, for sexual services, or simply to tie a naked businessman to your coal bunker with the clothes line and thrash his buttocks with wet stinging nettles, the income is taxable. There is absolutely no doubt about that, I’m afraid.
If you go onto the HM Revenue & Customs web site and type the word “prostitution” into the search box you will quickly find this:
If the activities of a prostitute or any other person deriving income from prostitution are organised in such a way as to constitute a trade or profession, the profits are liable to income tax. This was confirmed by the ‘Miss Whiplash’ case, CIR v Aken [1990] 63TC395.
