CD-419 | Application for Extension for Franchise and Corporate Income Tax  ·  S-Corporations  ·  Business Filing Guide

Overview

North Carolina S Corporations are subject to state business tax filing requirements, administered by the North Carolina Department of Revenue. North Carolina grants an automatic extension tied to an approved IRS extension, making the process simple for businesses that have already filed IRS Form 7004.

Original Filing Deadline

• The original due date for the North Carolina S-Corporations return is April 15, 2026. File or remit full payment by this date to remain in good standing.
• Extension Period & Extended Deadline
• North Carolina automatically grants an extension to file, provided you have obtained an approved federal extension from the IRS by filing IRS Form 7004. With a valid IRS extension, the North Carolina extended deadline becomes October 15, 2026. No separate state extension form is required—the federal extension serves as your North Carolina extension.

Payment Is Still Due by Original Deadline

The extension applies to filing only—it is not an extension to pay taxes owed. Any outstanding tax liability must be paid by the original due date of April 15, 2026 to avoid penalties and interest. Use the North Carolina | Online Tax Extension Payment to pay electronically. For mail-in payments, use CD-419 | Application for Extension for Franchise and Corporate Income Tax and send to: North Carolina Department of Revenue P.O. Box 25000 Raleigh, NC 27640-0520
