South Carolina Tax Brackets Explained

South Carolina uses a progressive state income tax system with multiple tax brackets based on taxable income.

Higher-income taxpayers may pay higher marginal tax rates, while lower-income earners are taxed at lower rates.

South Carolina taxpayers should also understand how state taxes connect to federal tax brackets, federal tax tables, and federal taxable income when preparing a federal tax return.

South Carolina Tax Brackets

South Carolina has simplified its income tax structure in recent years and may continue adjusting rates through future tax reform efforts.

How South Carolina Tax Brackets Work

South Carolina applies increasing tax rates as taxable income rises through bracket thresholds. Taxpayers only pay higher rates on the portion of income that falls within higher brackets.

Common filing statuses include:

• Single
• Married filing jointly
• Married filing separately
• Head of household

Because South Carolina taxable income calculations often begin with information from a federal tax return, federal tax brackets and IRS tax brackets remain important during tax planning.

Example: A taxpayer earning $85,000 does not pay South Carolina’s top tax rate on the full amount. Lower portions of income are taxed first at lower rates.

Who Must File a South Carolina Tax Return
