An automatic six-month extension is granted upon the proper filing of this form. An extension for a period longer than six-months may be granted if good cause exists; it requires the written approval of the Commissioner before it becomes effective. The Commissioner may terminate this extension at any time by mailing a notice of termination to the corporation or to the person who requested the extension for the corporation. The notice will be mailed at least 10 days prior to the termination date designated in the notice.

This application must be filed on or before the 15th day of the third month after the close of the taxable year, calendar or fiscal.

An extension of time to file a corporation tax return does not extend the due date for payment of the tax. Interest will be charged on any tax not paid on or before the original due date. Any tax not paid within the extended period is subject to a penalty of 1% per month, up to a maximum of 25%, from the extended due date.

The full payment of tax reasonably estimated to be due must accompany this form. If at least 50% of the tax due or the minimum tax (whichever is greater) for the taxable year is not paid, the extension is null and void.

Note: Under certain circumstances, if a payment is not required to be submitted with the extension request, the requirement to file the extension may be waived.

Corporations with $100,000 or more in receipts or sales must submit their extension request, as well as any accompanying payment, electronically. Also, any corporation making an extension payment of $5,000 or more must make the payment using electronic means.
