Tax Overview
This state uses a progressive income tax system with multiple brackets, similar to the federal system. Only the income within each bracket is taxed at that rate, so your effective state rate is lower than the top bracket. Tax planning strategies include maximizing pre-tax retirement contributions to reduce state-taxable income.
Tax Planning Tip
In a progressive-bracket state, pre-tax 401(k) and HSA contributions reduce your state tax bill along with federal tax. If you are near a bracket boundary, an additional contribution can drop you into a lower state bracket.
South Carolina's progressive tax system means each portion of your income is taxed at the rate for that bracket. The first $3,460 of taxable income is taxed at 0%, giving every filer a tax-free threshold. South Carolina does not tax Social Security benefits and offers a retirement income deduction for residents age 65 and older.
