State tax filing

Depending on your income, SC tax may be higher or lower than NC

 

NC is a flat 4.75% in 2023 (4.5% in 2024) on your taxable income (very close to but not the same as Federal Form 1040 Line 15)

 

SC tax is graduated from 0% to 6.3% of your taxable income (and is based on Federal Form 1040 Line 15)

 

at the lower income levels, there could be some due to NC; at the higher income levels it should all be due to SC.
