Thanks Mark, thats a very helpful view.
I imagine there would need to be a certain level of professionalism and quality in the short film – perhaps if it were to be accepted into a festival or two that would make it a quantifiable advertising expense (in advertising me as a filmmaker)?
Perhaps a large enough budget would also be needed, to separate it from home movies.
Thanks again Mark, it’s good to be able to narrow down the questions to ask a tax expert rather than the vague idea of filmmaking as a tax loss.
