Due dates

Individual Income Tax returns for a calendar year tax period are due April 15 of the following year.

A return for a fiscal year tax period is due by the 15th day of the fourth month following the close of your tax year. On the front of the return, complete the dates covered by the fiscal year.

South Carolina offers an electronic incentive until May 1, without being charged penalties and interest, if you:

  1. File your return electronically by the due date (April 15), and
  2. Pay your balance due electronically by May 1. 

If you don’t meet both requirements, penalties and interest will be charged from the tax due date (April 15) until you file and pay.

The May 1 electronic incentive doesn’t apply to federal returns or returns submitted by paper.
