South Carolina Income Taxes and SC State Tax Forms

efile South Carolina tax return
South Carolina
"The Palmetto State"

South Carolina State Income Tax Return forms for Tax Year 2018 (Jan. 1 - Dec. 31, 2018) can be e-Filed in conjunction with an IRS Income Tax Return until October 15, 2019. In January 2020, you can e-File Tax Year 2019.

eFile.com makes it easy for you to e-file your IRS and South Carolina State Tax Return (e.g resident, nonresident, or part-year resident returns). However, the IRS and the respective State Tax Agencies require you to e-file a Federal Income Tax Return at the same time you e-file a State Tax Return. This is not an eFile.com policy but an IRS and State Agency policy. Thus, technically you cannot e-File anywhere - not just eFile.com - a South Carolina Tax Return without also e-filing the associated IRS Tax Return. But there is good news, please read on.

Detailed instructions on how you can only prepare and mail in - not eFile - a South Carolina 2018 Tax Return - here via eFile.com. However, you must download/print and sign the forms and mail them to the Tax Agency.

South Carolina, IRS Late Filing, Tax Payment Penalties

1. Late Filing Penalty: This penalty is 5% of your total taxes owed if the failure to file your return is not more than one month after your SC tax return is due. You will be charged an additional 5% for each additional month or fraction of the month you file your return late, not exceeding 25%. 
2. Late Payment Penalty: This penalty is 0.5% of your total taxes owed if the failure to pay your tax is not more than one month after your tax is due. You will be charged an additional 0.5% for each additional month or fraction of the month you pay your tax late, not exceeding 25%. To waiver your penalties, complete and mail Form C-530, Penalty Waiver Request. Explain your reason for the waiver in Section II of the form. The South Carolina tax agency will then evaluate the request and decide whether to grant it or not. Be aware that interest is also computed on unpaid taxes that are owed from the deadline to the date when the entire tax is paid.

Automatic South Carolina Tax Extension

For Tax Year 2018 you can e-File an IRS Tax Extension by April 15, 2019 for free on eFile.com (instructions on whether you should consider a Tax Extension or not). 

If you are certain that you cannot file your South Carolina return by the deadline, you do not need to file for an extension. You will automatically receive a 6-month extension of time to file your return (not to pay). The extended tax return due date is October 15, 2019. Please be aware that South Carolina will not accept the federal extension form as an extension for your South Carolina tax return. However, if you expect to owe income taxes, you should submit your payment with extension payment voucher Form SC4868. If you efiled your return and are making a payment by check or money order, you must complete a Form SC4868 on efile.com. If you are making a payment by credit card, a Form SC4868 is not needed. If you are making an automatic extension payment, you also must use Form SC4868 unless it is made electronically. Use eFile.com and prepare a South Carolina tax return to find out what your South Carolina state income tax payment will be.
