I've seen previous commentary that medical certificates are not tax deductible because they are private. But is that correct?
If my employer says I don't get paid sick leave unless I produce a medical certificate, how is that not "incurred in gaining or producing [my] assessable income?"
Surely it's not of a "private or domestic nature" - who gets a medical certificate for the fun of it? Literally, the only reason I get one is to send it to my employer, and without it, it's unpaid leave. You can't get a more direct nexus between an expense and income than that.
So if I pay for the doctor's appointment, why shouldn't I claim it?
