I searched this out and read a lot of IRS tax bulletins. Have you read them?
Write-off is a term that I see misused. I now think of it as expenses in the business counting against the proifts of the business, not the expenses of the business counting against my income as a registered nurse.
Descriptions of beekeepers as farmers when they have little land ownership is not well understood by me. USDA folks (or similar US agencies) that run the honey loan program wanted to turn me away as I did not "farm a crop" when I asked about these programs.
I would develop an ongoing relationship with an accountant and let him help you out.
