With major tax cuts applicable to this year’s returns still under debate in the S.C. House and Senate, the S.C. Department of Revenue has extended the filing deadline for state income taxes until October 15.
Important to note: The extension only applies to those filing for a refund — not those who owe money.
“This extension applies only to the deadline to file your return, not to pay what you owe,” the department said in a statement. “You will owe penalties if you do not pay at least 90% of your 2025 tax liability by April 15, 2026.”
At issue in the legislature is a bill passed by the House earlier this month that would give state income taxpayers the same breaks included in President Donald Trump federal tax cuts bill last year. The S.C. Senate Finance Committee approved the bill Tuesday, but it hasn’t yet reached the floor for a vote.
If passed, the bill would cost the state treasury about $300 million this year, a number that would have to be reconciled during the budget process between now and May 14.
