   Consistent with the IRS, we extended the 2018 tax filing deadline from April 17 to April 18.
Following system outages, the IRS allowed taxpayers an additional day (until April 18) to file federal income tax returns. The SCDOR also allowed taxpayers this additional day to file state income tax returns. As in the past, South Carolina’s electronic filing incentive gives individual taxpayers until May 1 to file state income tax returns electronically and pay any balance due without penalty.

  What is South Carolina Individual Income Tax?

South Carolina has a simplified income tax structure which follows the federal income tax laws. South Carolina accepts the adjustments, exemptions and deductions allowed on your federal tax return with few modifications. Your federal taxable income is the starting point in determining your state income tax liability. Individual income tax rates range from 0% to a top rate of 7% on taxable income. Tax brackets are adjusted annually for inflation.

  Identity Verification & Individual Code Verification

The SCDOR has implemented new security measures to ensure that fraudsters are not using your information to file a false return and steal your refund. You may receive a letter from the SCDOR asking you to visit MyDORWAY to complete either the Identity Verification Quiz or Individual Code Verification after filing your return. This is just another step we are taking to keep your information private.
