> The relevant ruling on this subject came in 1994 in a case known as Hess v. Commissioner. The plaintiff, a self-employed exotic dancer, had implants that expanded her bust size to the size 56FF. For tax purposes, she treated these as a deductible business expense on her schedule C. The IRS contested her deduction.
But that aside, it seems to make sense to make the business and person the same when the business is you. No one else can truly replace that exotic FF dancer. Her clients die with her, and won't truly be replicated no matter what.
Odds are someone can be trained to do your paperwork and run your business. That may be the distinctive factor.
There is nothing I can do to engrave my body in a way that benefits by business. It’s an interesting case, but it seems to make sense. Buying a car for myself to use for my business doesn’t make sense at all; it’s actually bad for my business and creates a significant liability.
More applicable might be training, courses, certification etc (where you can clearly demonstrate a business purpose related to your current line of work).
For certain types of businesses the individual is almost indistinguishable from the business.
