My son worked started a new job last year and was on emergency tax for a few months as it was a small company and they had just lost their bookkeeper.When the new bookkeeper started he got his tax back.He should have received 2200 back but I just found out he received 6200 back.He says he asked his employer if this was a mistake and they said no so he spent the money.He is a student and only told me today.How will they make him pay this back?
