Delaware, Montana, New Hampshire and Oregon have no state sales tax. $100,000 in sales to California is close to nothing; I can't imagine there are many retailers online who don't reach this threshold. In my experience, (almost) all online retailers now automatically add my local sales tax once they know the shipping address. I assume they have software that performs this function automatically.Sales tax collection is only required by retailers after a certain threshold of sales is made to each state and that varies by state. I'm not familiar with any state that has no sales tax these days. In the case of Georgia where I live, it's $100,000 in sales or 200 transactions for the state. That means small out of state retailers are not unduly burdened. Most retailers have to use a service to keep up with the astounding number of sales taxes and jurisdictions. In my case I have state, city, county, and transportation taxing authorities each with their own rates.
