I have had my application for tax relief on PE kit approved by the Inland revenue. They have increased my tax code for this tax year and the next and I'm to get a rebate of tax for past tax years. For all tax years from 2008/09 you can offset £60 against tax (paying £12 less in tax if a 20% taxpayer) and for 2006/07 and 2007/08 you can offset £45 against tax (rebated £9 each year if a 20% taxpayer). You msut be able to say that you provide, repair, replace and launder your own kit, needed for work only, and the employer does not provide laundry facilities. I work on supply and teach PE sporadically, sometimes a full day and odd lessons at other times on general supply in the Secondary sector. I keep T shirt, jogging trousers, sweatshirt and trainers in the car in case required.
