Staff reports
The South Carolina Department of Revenue (SCDOR) is extending the tax filing due date for all 2025 South Carolina Individual Income Tax returns to October 15, 2026.
This extension applies only to the deadline to file areturn, not to pay what isowed. S.C. taxpayers will owe penalties if they do not pay at least 90% of their 2025 tax liability by April 15, 2026.
According to a media release by the SCDOR, the South Carolina Legislature is working on House Bill 3368 to conform with the current Internal Revenue Code, including the One Big Beautiful Bill Act (OBBBA). If passed, the SCDOR will provide additional information as soon as possible, including guidance for taxpayers who have already filed their 2025 Individual Income Tax returns.
No action is required to take advantage of the filing extension. MyDORWAY is the fastest, easiest way to pay a balance. Visit and select Individual Income Tax Payment to get started.
If expecting a refund, taxpayers do not need to do anything except file their return by Oct. 15.
The SCDOR will publish additional guidance and updates through our website and social media channels.
