The South Carolina Department of Revenue is changing the process for amending South Carolina Individual Income Tax Returns in 2020.
Beginning with tax year 2019, you will use the SC1040 to amend South Carolina Individual Income Tax Returns (SC1040),
A new Amended Return checkbox will be included on the 2019 SC1040. Simply check the Amended Return checkbox and complete the return as it should have been filed. Submit all schedules and necessary attachments, including the new Schedule AMD, with your amended SC1040.
The new Schedule AMD and the 2019 SC1040 will be available on dor.sc.gov in early January. Please continue to use the SC1040X to amend returns for 2018 and earlier tax years.
