Bitcoin doesn't fix it please don't be like that. If the tax is included in the charge btc doesn't change anything the only difference you will see is on a btc receipt everything isn't itemized. On a nornal sales reciept tax is seperated from sub-total then total at bottom. So if someone on btc is charging you $35.74 you have to decide yourself did that person just include their states sales tax in the price? People will use btc like a creditcard they will enter the total in the invoice which will include sales & if this passes digital tax & then they will go how do you like to pay? Btc okay put ur phone here like the bypass chip in debt cards.
