Hi, I was wondering, is anyone legally registered as self employed and gives receipts to their customers? I am thinking about trying and get legal and offer receipts as for any other service and pay tax. thank you

Thank you Dani.
Right, here comes the stupid bit...how do I do it, what do I declare myself as to the authorities?

Thank you DianaMurphy,

the thing is, I am a foreginer and I haven't got a national insurance number and have tried to get one for my day job, which is self employment as well, but unrelated to adult entertainment,  and they rejected my application. I am only wondering, let's say I schedule an interview with them again for escorting .. what do I say to them that I work as? I would feel uncomfortable to say I am an escort and let's say that this is what I will successfully get registered as, would it show on all my life's records that I am an escort? thank you

You could just tell them about your other self employed position without stating you are an escort, the only problems may arise if you start claiming on your tax return for things which are for escorting but not relevant to your other self employed position. You'd be best seeking help from an accountant really.

Edited to add: This page has information on how to obtain a national insurance number http://www.hmrc.gov.uk/migrantworkers/uk-tax.htm

I've been self employed for over ten years as a freelance PA and administrator as I that is what I have been doing in this time. There are quite a few threads with ideas of what to tell the tax man which you'll be able to find through the search function 

you dont have to physically give receipts but I right one for every booking. This helps with my paperwork as I have several income streams.

Think about what you want to put your work as otherwise there are things you cannot claim for.  I claim for condoms, certain items of clothing that I would not wear in normal life, all my toys as well as the rent and bills on my work apartment.  I claim as an escort but you could just put adult entertainment or webcammer etc as then at least you can still claim for certian things.
For instance a PA cannot claim for a seprerate work flat, A masseusse cannot claim for condoms and toys or PVC outfits

I cannot understand why they refused to give you a national insurance number though as everyone who is entitled to live and work here is entitled to one and is infact expected to have one otherwise it is impossible to get employed by any company

Danielle, all sex workers are self-employed - you need to be registered as soon as you start and certainly within three months. It doesn't matter what you put on the registration form within reason; my accountant recommends therapist (since it's a meaningless term that could and does cover all sorts of things) and as others have suggested you can use adult entertainer (or just entertainer), or masseuse or whatever. You can claim for anything that is used exclusively in the process of going about your normal business and that includes condoms, lube, advertising, transport and all the rest - there is a lot of helpful information in a lot of threads on the forum already if you use the Search box and type 'tax', 'HMRC', 'self employed' and so on.

You could also have a read through 'Tax Relief 4 Escorts' here which is good, but far and away the best thing to do is ring the tax office. They'll be able to advise on not only the general stuff but also help with any special circumstances and they're always very helpful.

In answer to your question, what goes on your tax return is between you, HMRC and your accountant if you decide to use one. It is nobody else's business but your own.
