Hello, I am looking to start tutoring in the coming months. At the moment I only want to take on a couple of students as I will be doing this alongside my full time job. I will of course be declaring my earnings and doing a tax return - if I only take on a couple of students, am I going to be stung tax wise? - I hope I will earn an extra £200 a month - but will this then effect the tax I pay on my full time job earnings. I hope this makes sense! I just know from taking a 'second' job in the past, sometimes it has hardly been worth it once tax has been adjusted for both jobs.
