My 18yo is on their 2nd part time job, the first was only a few weeks as it was horrendous all round. They are being taxed quite a bit although they are earning under the threshold. From what I can gather it's due to the first job not giving her a P45, there's no way she get them to give her one but I'm not sure how to help. Does anyone know what we should be doing to get it sorted without waiting till April?
