The Commissioner has authorized the Internal Revenue Service Center, Philadelphia, Pennsylvania (for all purposes except venue), to receive Form 1120. Except for that authorization, A, a corporation with its principal place of business in Greensboro, North Carolina, is required to file its Form 1120 for Year X with the Internal Revenue Service Center, Atlanta, Georgia. In addition, A may file an election to defer development expenditures paid or incurred in Year X. Under § 1.616-2(e)(2) and applicable published guidance (in this case Notice 2003-19 (2003-1 C.B. 703)) that statement of election must be filed with the service center that serves A's principal place of business where A filed its income tax return. A may make that election on its income tax return or by filing it separately. Under paragraph (a)(2) of this section, A may send its Form 1120 to either the Internal Revenue Service Center, Philadelphia, Pennsylvania, or to the Internal Revenue Service Center, Atlanta, Georgia. If A files its statement of election separately from its income tax return for Year X, then the statement of election is not a proper attachment to A's income tax return and A should send the statement of election to the Internal Revenue Service Center, Atlanta, Georgia (with which A must, without regard to paragraph (a)(2) of this section, file its income tax return), no later than the time prescribed for filing Form 1120 for Year X (including extensions).
