State of Georgia Business Income Tax Extensions

E-file an IRS business tax extension with

General Instructions

Georgia corporation tax returns are due by the 15th day of the 3rd month after the end of the tax year (March 15 for calendar year taxpayers). If you need more time to file, you can obtain an automatic state tax extension. A Georgia business extension will give you 6 extra months to file, which moves the filing deadline from March 15 to September 15 (for calendar year filers).

If you have a valid Federal business tax extension (IRS Form 7004), you will automatically receive a corresponding Georgia tax extension. Just make sure to attach a copy of Form 7004 to your Georgia tax return when it’s filed.

If you do not have a Federal extension, you can apply for a Georgia business extension using Form IT-303 (Application for Extension of Time for Filing State Income Tax Returns). Note that you will have to provide a reason for requesting an extension on Form IT-303.

Your Georgia extension request must be filed by the original deadline of your return (March 15 for most businesses).

Keep in mind, a tax extension only gives you extra time to file, not to pay. Any state tax balance you owe must still be paid by the original due date (March 15). You can use Georgia Form IT-360C (Corporation Income/Net Worth Payment Voucher) to make a state tax payment when an extension is being requested. Or, you can make an extension payment online at the Georgia Tax Center (GTC):
