South Carolina boat tax appeals
South Carolina taxes your vessel every year. If the assessed value is too high, we appeal it — $0 upfront, and a fee only if the value drops.
How South Carolina taxes your boat
South Carolina assesses boats at 10.5% of fair market value and applies local millage, though some counties reduce the ratio to 6% or exempt 42.75% of value by ordinance.
