Hello,

I just started my online business a few days ago under Shopify, mostly selling products for “self care” jewelry, Crystals, handbags, oil diffusers , lights etc. I am in New York and very new to all of this should I be taxing my items? Do I need a LLC or a business  license. When comes down to tax time I want to make sure i have all my ducks in a row. Please help! Thank you’
