Tax class for short-term employment in addition to mini-jobs

Hi. I am a student and actually work in a mini-job relationship. I occasionally take on shifts through Zenjob (a temporary employment company with short-term employment). Since mini-jobs are tax-free, I'm not sure if I should specify tax class 1 or 6 for Zenjob. I would be very grateful for your input. submitted by /u/ma_ri14 [link] [comments]
