Hello! I started to supply this September with two agencies, one which pays me a lot more generously than the other. I've just been contacted by a school who would like to employ me as a supply as and when they need me, fitting around my commitments with my agency work. The school said this: We would employ you as a casual employee rather than take you on via an agency and you would be paid via payroll for any work that you do. So my question is how would this effect my tax with essentially three employers, two of those being agencies and one being via payroll? Am I going to get a higher tax rate on the direct with school work? I am just not really sure how any of this works so could do with a financially savvy person to guide me! Hope that makes sense?! Thank you!
