My son is 18yrs old ,he has been at college for the last 2 yrs , so no income earned,
He has been working through a agency for the last five weeks consisting of 5 days a week,
He hasn't had any tax stopped from his last 5 weeks wages , is this right as he is worried he will have to pay it all back.
He is employed not self employed , he has had national insurance deducted
Please help
