I doubt that it is an attempt to fish for taxes. But there is no good reason to let yet another bureaucratic entity know what you do at your homestead. Like I found out trying to get USDA grants; the risks, intrusion, paperwork and red tape are not worth the effort you put in.So I applied to get scrapie tags for my sheep/goats, and now I got a survey from the usda who's doing a search on farming operations. Call me paranoid, but I would be concerned if they would use the information to fish for taxes. I am not sure how to answer this thing.
