Affiliate Marketing Secrets

I have been accepted into some basic networks and 2 privately owned networks, as well as forming a good relationship with a product owner who says I have permission to directly advertise her product. I have been trained for the past few weeks but nobody in the industry has ever mentioned anything about LEGAL stuff. I’ve never had a job or career before, fresh out of school. Don’t know a thing about taxes, where can I learn how to do things legally?>
I know some big “gurus” who’ve been jailed, mostly for fraud and OBVIOUS trickery. I’m not planning to be deceitful, but like everyone else in the industry it’s in my best interest to avoid paying taxes (legally) and for that I need to be educated on laws… A thing I wish they would teach in schools.
