Is the tax rate calculated against the zip code of the shipper or the end purchaser?

What is the effective date? For states that tax sales and services, is that from today forward or back to some statute of limitation date?

Even if we talk about today, if I make an online sale today that is subject to some state's existing tax code, am I liable now?

Maybe I charge a 10% tax on all transactions to cover potential tax liabilities?

Any business and tax lawyers out there, any accountants, with an idea on how this changes things for today, tomorrow, and for the past?
