Hello, I am currently working one job as part-time and earn £446.25 per week before tax and tax code is 688L. I am about to start a second job and will earn £343 per week before tax (this is a hospitality job so there is a plus tronc agreement, I have not included this in the weekly salary) Will I have to pay 40% tax on the second job? Or will it stay at 20% as my first job? Thank you
