I'm hoping someone with Tax experience can advise. I'm sure the answer is no, but... I'm an engineer working as a sole trader. There is bugger all I can claim off the tax man. I'm wondering, If I get stickers with my company name made up and put them on my bike, then ride on Trackdays, can I then claim the cost of the trackday as an advertising expense? I see a lot of the fast guys on the track have advertising on there bikes - so assume there being sponsored (and someone is claiming something on tax). I guess I'm effectively sponsoring myself? My guess is you might be able to do this if your actually "racing" but probably not just for a track day? Thanks in advance.
