What kinds of things are "written off" , and what kind of money are we talkin' about here Really? I've heard you can do this too, but I've also heard Republicans are for smaller government so... *shrugs*...
Direct business expenses. So having to get professional level insurance, having to get gear you would not normally have other than required to teach classes. Fuel to get to dive sites that is not otherwise reimbursed. Stuff like that. There is a bit of wiggle room here, but if you claim every piece of gear you buy, you will possibly trigger an audit. Don't get greedy and you can claim quite a bit, but just remember if you get an audit, you need to be able to justify it as a legitimate business expense
