How to register and pay for your taxes » Part-time job while self employed » Go to message
I registered for self assessment tax in July and will be applying for a part-time job soon.

What do I need to tell HMRC if I get the job and how do I deal with the income for my tax return?

Would I simply declare it in January 2018 with my self assessment?

Is there anything else that needs to be done if I become employed while also doing self assessment?

Thanks for your help.
