If yes, attach a copy of the federal audit or adjustment. Yes No FILING AMENDED RETURNS For tax years 2018 and before, use the SC1040X to correct or change the SC1040 that you have previously filed. For tax year 2019 and later, amend your return using the SC1040, marking the amended return check box and attaching the Schedule AMD. An amended return can be filed only after you have filed an original return. By filing an amended return you are correcting our tax records. An amended return is necessary if you omitted income, claimed deductions or credits you were not entitled to, failed to claim deductions or credits you were entitled to, or changed your filing status. You should also file an amended return if you were audited by the IRS (unless the IRS audit had no impact on your state return). Your amended return may result in either a refund or additional tax. You must pay any additional tax with the amended return. Furnish all information requested. When items are in question, refer to the instructions for preparing the SC1040, SC1040TC, I-385, or I-319 when applicable. Be sure to include a copy of your federal 1040X if you were required to amend your federal return. Round all amounts to the nearest dollar. Any overpayments will be refunded. Overpayments cannot be transferred to another tax year. NOTE: South Carolina law does not allow a net operating loss carryback. If you filed your original return by the original due date or by an extended due date, if applicable, you must file any claim for refund within either: • three years from the date of filing, or • three years from the original due date, or • two years from the date of payment If you filed your original return after the original due date and any extended due date, if applicable, you must file any claim for refund within either: • three years from the original due date, or • two years from the date of payment When amending a return for tax year 2018 and before, use the most current revision of the SC1040X regardless of tax year.

South Carolina usually releases forms for the current tax year between January and April. We last updated South Carolina Form SC1040X from the Department of Revenue in January 2024.
Form SC1040X is a South Carolina Individual Income Tax form. An amended tax return is used to correct errors or omissions in a previously-filed tax return. While taxpayers will not generally be punished simply for correcting an error in a previous return, errors that resulted in an underpayment of owed tax can sometimes result in penalties or interest owed.
About the Individual Income Tax
The IRS and most states collect a personal income tax, which is paid throughout the year via tax withholding or estimated income tax payments.
Most taxpayers are required to file a yearly income tax return in April to both the Internal Revenue Service and their state's revenue department, which will result in either a tax refund of excess withheld income or a tax payment if the withholding does not cover the taxpayer's entire liability. Every taxpayer's situation is different - please consult a CPA or licensed tax preparer to ensure that you are filing the correct tax forms!
We have a total of twelve past-year versions of Form SC1040X in the TaxFormFinder archives, including for the previous tax year. Download past year versions of this tax form as PDFs here:
