tax on second job

Hello I would like to ask a question, so in my current main job Im earning 47K but thinking about getting second part time job which would take me above 50k. Obviously then I'm hitting on anything above 50K another tax code. So my question is would my correct employer be notified of my tax code change if I decide to take second job? Or my tax code would remain the same for main job, and be different only for the new part time job? Thank you

Hi,

If you are starting a new job, you would complete a starter declaration form. You would select option C which is that this would be your second job. You would perhaps be better calling HMRC after the fact to ensure that we have your estimated income correct. The tax code for your primary source may change depending on how much of your income is taxable at the higher rate. See link below:
