||How to File
If you need more time to file a South Carolina state tax return and you have filed an extension to file your federal return,you are allowed the same extension of time to file your state return as as the one offered by the IRS. To receive a state return extension, attach a copy of your federal return extension request to your state tax return when you file it.
If you did not receive an extension to file your federal return but only need an extension to file your SC tax return, use Form SC4868 to request a state return extension. File the request on or before April 18th, 2018, or before the original tax return deadline. The extension will give you an additional 6 months to file your SC state return. If no income tax is anticipated to be due and you have been given a federal extension of time to file a federal tax return, the SC state tax department will accept a copy of the federal extension. In this case, you do not need to send a copy of the federal form by the tax return deadline. File your extension and pay your balance due on-line at www.sctax.org or file Form SC4868. Mail the original with payment if any. Be sure to check the appropriate box when filing your SC1040 to indicate if you have filed a state or federal extension. Keep two copies: one copy should be attached to the back of your return when it is filed, and the other should be retained for your records.
A failure-to-file penalty is imposed for failing to file a SC tax return on or before its due date, determined with regard to any extension of time for filing. The penalty is 5% of the tax amount if the failure is for not more than 1 month, with an additional 5% for each additional month or fraction of the month during which the failure continues, not to exceed 25%.
The extension of time to file your SC return doesn't extend the time for paying any tax owed. A failure-to-pay penalty is imposed for failing to pay the amount shown as tax on any SC return on or before its deadline, determined with regard to any extension of time for paying. The penalty is 1/2% of the amount of tax if the failure is for not more than 1 month, with an additional 1/2% for each additional month or fraction of the month during which the failure continues, not to exceed 25%.
Complete and submit Form SC4868 (if you did not file federal extension)

SC Personal Property Tax:
Personal and real property tax is administered and collected by local governments with assistance from the South Carolina Department of Revenue.
Approximately two-thirds of county-levied property taxes are used to support public education.
Municipalities levy a tax on property situated within the municipality's limits for services provided by the municipality. The tax is paid by individuals, corporations, and partnerships owning property within South Carolina.
Each class of property is assessed at a ratio unique to that type of property.
- Primary residences at 4% of fair market value.
- Privately-owned agricultural property at 4% of use value.
- Personal property at 10.5% of income tax depreciated value.
Each municipality and county then applies its mileage rate to the assessed value to determine the tax due. The mileage rate is equivalent to the tax per $1,000 of assessed value. Homeowners should contact their local county assessors for specific mill rates, since the mileage rates vary among districts.
The first $100,000 in the fair market value of a primary residence is exempt from school operating costs.
South Carolina provides numerous property tax exemptions. One of the exemptions is a homestead exemption of $50,000 from the property's assessed valuation. It is available to residents who are 65 years of age or older, who are totally disabled and/or who are totally blind. The exemption is granted by the county auditor; taxpayers are required to file an application with the county auditor in order to claim the exemption.
Odd Tax Fact:
