My advice to you is to come off benefits right now and register with Inland revenue for damage limitation.

In fairness depending on what sort of sex work the OP offers she could have a illness/ health issues and would be able to still claim universal credit and work a bit

If she mainly did camming  / phone chat & online stuff  and the occasional escort job she would be able to get help via universal credit depending on what her health issues are

Hi so I am a  sex worker and I am on viva and aw and I dont pay my taxes and I do get Public funds I wanted to know what's the safest bank account to deposit escort money if anyone who deposits money which bank do they recommend

So far Lloyd's and Halifax closed my accounts down without reason

As it’s been said here by others. Aw are sending our details to hmrc next year, Universal credit have put in place to catch out people working while claiming by banks and reviews.
But even before this Adultwork always had your ID and at any given time hmrc could have requested it.

Let me get this right .
The op called over £40k without paying tax and is claiming benifits

Wow !

Totally foolish and so morally wrong in actually angry

OP:
Someone may "get away" with earning some small amount of cash and not declaring it for tax - and when i say small I am thinking of like £1,000 or less in a year -- so its a hobby income!
But if you are living on benefits, then it isn't worth taking risks.

And if you are earning a substantial sum - that is enough to pay your bills, you have to register as self-employed, keep records.
There is no way to keep this income secret from the Inland Revenue over the long term.

Really - the easiest way to manage it is to speak to an accountant.

* End the benefits ASAP
* Contact the inland revenue and tell them you will be self-employed as --- some kind of therapist - or have the account ant do that for you.
* When you contact the Inland Revenue they will ask you to estimate what your income will be and when you are starting this business so think about your answers - although you should be honest and go back to whenever you started... perhaps you might decide to say you have just started it now- ty and get yourself straight going forward and hope no one looks into the past -- IDK if that will work but it is better than carry on hoping to get away with it - you could face prison.

I would suggest you underestimate your income because they ask you to pay Income Tax in advance, so that's a big tax bill straight away - eventually, the tax will even itself out.
