South Carolina is quite favorable to retirees.
Property tax rate is among the lowest in the nation. But sales tax is relatively high.
However, income tax is VERY favorable for retirees. A $30k exemption on retirement income for married couples. Plus Social Security is not taxed.
So, a married couple with $100k will pay little to NO income tax in South Carolina.
Low income tax, low property tax and a moderately high sales tax, makes South Carolina VERY favorable for retirees.
