Sponsorship

Dear Sir/Madam,

A while ago, a friend of mine asked me if I would sponsor him in his sport in exchange for printing my logo on his kit. I read in an article from Dexter that I can simply enter this.

However, I also run marathons and such. I was wondering if I could sponsor myself by submitting invoices for my running shoes, for example, and in exchange have a running outfit made with my logo on it.

Does anyone know if the tax authorities will accept this?

Thanks in advance!
