Important: If you owe income taxes to North Carolina or the IRS and fail to file a tax return or extension by the due date, you will incur late filing penalties from both agencies. Additionally, if you do not pay your taxes by the deadline, you will face
late payment penalties. Filing an extension on time will only waive the late filing penalties, not the late payment penalties. Since late filing penalties are usually higher than late payment penalties, it’s crucial to file your return or extension on time, even if you can't pay the taxes owed immediately.
