PAYE Employed + Uber Eats

Hello, I am looking for some advice on my situation. I am currently Employed under PAYE and as an additional form of income I delivery using the Uber Eats platform. I have a few questions; 1: Do I need to register as self employed? If so - Will this affect my PAYE role? 2: Can I pay the tax on a monthly basis to ensure it's paid? Thanks,

Hi ,
 

Yes you will need to register : Set up as a sole trader: step by step   . If paying your tax on a regular basis, it wont affect your PAYE tax code .

Thank you .
