South Carolinians can officially start checking “file taxes” off their to-do lists later this month.
The South Carolina Department of Revenue announced it will begin accepting 2025 state income tax returns on January 26, 2026, with the filing deadline set for April 15. That gives taxpayers just under three months to file, but state officials say preparing early can help avoid unnecessary stress — and potential problems.
What to Expect This Tax Season
For many households, tax season brings a mix of anticipation and anxiety. Some families are counting on refunds to help offset rising costs, while others are carefully budgeting to pay what they owe.
The Department of Revenue encourages residents to file electronically and choose direct deposit, which can significantly speed up refunds and reduce processing delays.
USPS Changes Could Impact Mailed Payments
Taxpayers who still mail their returns or payments are being urged to take extra precautions this year.
State Treasurer Curtis Loftis warns that recent changes by the U.S. Postal Service could affect when mailed tax payments receive an official postmark, potentially causing payments to be considered late — even if they are dropped off on time. Under the updated USPS process, mail may not always be postmarked the same day it is received at a post office.
“If you’re mailing a tax payment, don’t wait until the last minute. A delayed postmark could mean penalties or interest, even if you did everything you thought was right.”

How Taxpayers Can Protect Themselves
To avoid penalties or interest, officials strongly recommend:
- Filing and paying electronically whenever possible
- Mailing payments several days before the deadline
- Using a staffed post office counter rather than collection boxes
- Keeping proof of mailing in case of disputes
- Avoiding last-day drop-offs altogether
Free Filing Help Available
Taxpayers looking to save money on preparation costs should know that free, trusted filing options are available through the IRS. Individuals who qualify can use IRS Free File, which offers guided tax preparation through participating partner companies at no cost.
More information, eligibility details, and links to approved free filing partners are available at IRS.gov, the official website of the Internal Revenue Service.
Helpful Resources and Reminders
Taxpayers with questions about deductions, credits, or filing options can also find guidance on the South Carolina Department of Revenue’s website or consult a trusted tax professional. Residents are urged to remain vigilant against tax-related scams, which tend to increase during filing season.
With tax season officially opening January 26, state leaders say early action is the best way for South Carolina families to protect both their finances and their peace of mind.
