What a pleasant surprise as much as I love South Carolina and it is a low tax state. Only lived now in North Carolina for less than two weeks I have found out the sales tax is 2.25% less than 4 miles over the border in South Carolina my personal vehicle rate here in North Carolina is tremendously lower than what it was in South Carolina, but with that said, I believe that’s mostly dependent on County and I happen to live in the highest taxed county in South Carolina before we moved which was still boatloads and boatloads and boatloads cheaper than Long Island, New YorkMany of those articles about low-tax states tout Virginia's "low" property tax rates (they aren't really that low in any part of the state with employment more substantial than "Wal-Mart Greeter") but somehow overlook the personal property tax (aka the "car tax") which is pretty high.
One nice benefit in South Carolina is the maximum sales tax on any vehicle is $500 no matter what price you pay including boats.
