Residency & Filing Requirements

Residents: You are a South Carolina resident, even if you live outside South Carolina, when:
  • ​Your intention is to maintain South Carolina as your permanent home; AND
  • South Carolina is the center of your financial, social, and family life; AND
  • When you are away, South Carolina is the place to which you intend to return.

Nonresidents: You are a nonresident if your permanent home is outside South Carolina all
 year and none of the above apply.​

Nonresidents or part-year residents are required to file a South Carolina return if they work
 in South Carolina or are receiving income from rental property, businesses, or other
 investments in South Carolina.

Due Dates

Individual Income Tax returns on 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. 

Got questions on how to file?


​Did you receive an Identity Verification Notice?

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