How do I find out how much tax I would have to pay if I got another jobs that was part time? I currently work full time and I am looking for another job as part time. How much in % would I be taxed for it?
You would be taxed at basic rate which is 22% (so for every �100 you earn, you will pay �22 in tax)
You probably won't pay any additional NI as its likely you will be under the minimum NI earning threshold.
