Hi, Can you claim tax relief for mileage and home office on self assessment? I have found where to enter charitable donations but not job expenses I am an employee but claim high income child benefit so have to do a self assessment (not knowingly I been PAYE incorrectly for past 2 tax years) I have drafted my SA but it is estimating I need to pay for all the child benefit, which is fair enough. However a lot of this will be offset by my job expenses and charitable donations.
