You do not need to request an extension to file your Georgia return if you receive a Federal extension. The due date for filing your Georgia return will be automatically extended with an approved Federal extension. Attach a copy of Federal Form 4868 or the IRS confirmation letter (if you request a Federal extension electronically) to the Georgia return when filed. Contact the IRS at 1-800-829-1040 or visit their website at www.irs.gov to obtain Form 4868 and additional extension information.
