Our apprentice came back to us after spending 20 weeks in FAS. How do I handle his tax? If I continue as normal then he'll pay no tax having had a break of 20 weeks in employment. I'm inclined to tax him on a week one basis so he won't end up having to repay tax at year-end. FAS made no deductions from his basic allowance and we didn't get a P45 at the end of his stint. It's coming to the end of the tax year and I'd like to do things properly. Any advice?
