Most buyers pay cash. I do.
But, there have been a few times when I've had to use a check because the lots of ginseng on the table were bigger than the cash in my pocket.
The thing to remember is that ginseng buying is a business. Just like the fur industry, the IRS is getting wind of the money moving around the country attached to ginseng. Any ginseng dealer who approaches his business as anything more than a hobby stands to lose too much to cheat on his or her taxes. That means we have to pay taxes on our business. That means we have to keep records. We are also required to keep records of our purchases and sales. So, it is only a matter of following the paperwork if some IRS guy wanted to track you down associated with not paying taxes on a good digging year's ginseng profits.
Just as with everything else, following the rules is normally the best way to stay out of trouble.
