I live in California. I am starting my new business on Shopify where I will be selling digital products. Customers will purchase the digital products on my website and I have an app that will email them the download.

My question is, do I need to apply for a California Seller’s Permit? I have read mixed things about the requirements. The www.cdtfa.ca.gov website states that you need a Seller’s Permit only if you are selling “tangible” items, but on the other hand it also sounds like a Seller’s Permit is required if you want to charge your customers sales tax(which I do). Anybody that sells Digital Products have any advice on this? Thanks
