Understanding the intricacies of South Carolina’s tax system, including corporate income tax, individual income tax, deduction opportunities, and tax return procedures, is essential for residents and businesses aiming to remain compliant and optimize their financial planning. This comprehensive guide delves into the state’s tax structure for 2025, highlighting recent changes, retail sales taxes, the gas tax, current tax brackets, and available extensions.
South Carolina employs a progressive income tax system, which means that tax rates increase as income levels rise. As of 2025, the tax brackets are structured as follows:
These rates apply uniformly, regardless of filing status. It’s noteworthy that South Carolina’s top marginal rate of 6.4% is among the higher state income tax rates in the U.S. This progressive system ensures that those with higher incomes contribute more, reflecting a commitment to equity and fairness.
In late 2024, the South Carolina Legislature proposed a bill (Bill 3498) aiming to amend individual income tax rates. The proposed tax code structure would tax the first $1,000,000 of taxable income at %, with the top marginal rate applying to amounts exceeding $1,000,000, reflecting changes that taxpayers might notice in their tax return, while corporate income tax rates remain unchanged. As of now, this bill is under consideration and has not been enacted into law. This potential change could significantly impact high-income earners, offering substantial tax relief, while also affecting tax revenue generated by the state.
The state imposes a base sales tax rate of 6% on most goods and services. Local jurisdictions have the authority to levy additional sales taxes, which can add up to 3%, bringing the maximum possible combined sales tax rate to 9%. For instance, in cities like Charleston and Greenville, the total sales tax rate reaches 8%. Understanding these variations is crucial for businesses and consumers alike, as they navigate daily transactions.
South Carolina boasts relatively low property tax rates compared to the national average. The average effective property tax rate is approximately .57%. Additionally, the state offers a homestead exemption for homeowners aged 65 and older, exempting the first $50,000 of a property’s fair market value from local property taxes. This exemption provides significant relief for seniors, allowing them to enjoy their golden years with reduced financial burdens.
For the 2025 tax year, South Carolina income tax returns are due on April 15, 2025. However, taxpayers have been granted relief until May 1, 2025, providing additional time to file. If more time is needed, taxpayers can request an extension, which typically aligns with federal extension procedures, and may choose to e-file to ensure a timely submission. It’s crucial to note that while an extension grants extra time to file, it does not extend the time to pay any taxes owed.

No, South Carolina exempts Social Security benefits from state income tax, providing peace of mind to retirees who rely on these benefits.
Taxpayers can request an extension by filing Form SC4868 by the original due date of the return. This extension grants an additional six months to e-file the return. Remember, this is an extension to file, not to pay. For detailed guidance, explore Personal Tax Extensions.
No, South Carolina does not impose an estate or inheritance tax, allowing families to pass on their wealth without additional state tax burdens.
