Hi, I have been on the NHS Staff Bank (zero hour contract) for a number of years but they outsourced all of us to NHS Professionals (NHSP). I now work 100% for NHSP but I haven't officially resigned from the NHS who still hold my P45. NHSP are my Primary Employer. Does the fact that the NHS still hold my P45 affect how much tax I pay? I know it seem like a daft question but I technically have two employers. I got paid my first full month from NHSP and I got clobbered for over 30% tax. I'm being told it will even out over the next month or so. Any thoughts?
