answer:You might not need to charge any tax. The old rule was to tax only if the business had a store in the state being shipped to. The tax charged would be the ship to state’s tax. So for instance if I buy something from Bloomingdale’s and have it shipped to my home in TN, no tax, because there is no Bloomies here. But, if I ship it to my MIL it is taxed at her county’s tax rate in FL, because there are Bloomies in that state. I think the laws might still work that way, because I order exercise clothing from a website, and I am never charged tax. An accountant should know. The accountant can also help you set up your books for the business and inform you what to keep track of, how to pay any required quarterly taxes, etc.
