I have been trying to find the answer to this for weeks and nobody seems to know. I can't even find the answer by googling my question. So I'm hoping someone in here can answer it. I am confused about the sales tax. I don't understand why it's up to us to type in what the tax rate is for each state. Are we supposed to research what the tax rate is in each state and go down the list and type each number in? If it's the same for everyone, why do these sites make us do this? What if somebody typed in the wrong number? I basically don't understand this at all and need someone to explain it to me in detail using laymans terms. I am starting to feel like I am not smart enough to do this and I am very discouraged at the moment.
