New to camming - is income taxable?

[Polet]

Hey! Hope you're all doing well

I've started camming a while ago and made a little chunk of money from it but I'm getting a bit concerned about tax - I work part time so make just under the first tax band here in the UK, and eventually any extra money I make will end up being taxable. I have been putting my numbers into this tax calculator (here: https://www.income-tax.co.uk/) and it says I am extremely close to the next tax band. How do I go about paying tax on this income? Hoping someone here can explain it a little better to me

Thanks, and hope to see you around soon!
