 Under penalty of perjury, I declare that I am an officer of the corporation authorized to act on behalf of the above-named corporation, and that I have examined 
 the information on its 2020 New York City electronically filed corporation tax return, including any accompanying schedules, attachments, and statements or 
 other report checked above, and to the best of my knowledge and belief, the electronically filed corporation tax return or other report is true, correct, and com-
 plete. The ERO has my consent to send the 2020 New York City electronically filed corporation tax return or other report checked above to New York City De-
 partment of Finance through the Internal Revenue Service. I authorize the ERO to enter my PIN as my signature on the 2020 New York City electronically filed

 port. If I am paying the New York City corporation tax owed by electronic funds withdrawal, I authorize the New York City Department of Finance and its des-
 ignated financial agents to initiate an electronic funds withdrawal from the financial institution account indicated on the corporation’s 2020 New York City 
 electronically filed corporation tax return or other report, and I authorize the financial institution to debit the amount from that account.

 Under penalty of perjury, I declare that the information contained in the above-named corporation’s 2020 New York City electronically filed corporation tax return or other report 
 checked above is the information furnished to me by the corporation’s authorized officer.  If the corporate officer furnished me with a completed 2020 New York City paper cor-

 return or report is identical to that contained in the paper return or report. If I am the paid preparer, under penalty of perjury I declare that I have examined this 2020 New York

PURPOSE - A completed Form NYC-579-COR provides documentation that an ERO has been authorized to electronically file the Business Corporation Tax return or other 
report. The officer of the corporation who is authorized to sign the corporationʼs returns may designate the ERO to electronically sign the return or other report by entering 
the officerʼs personal identification number (PIN). The form also authorizes payment of tax due on an electronically submitted return or report by an automatic clearing house 
(ACH) debit from a designated checking or savings account of the corporation. You cannot revoke this authorization. 
 
GENERAL INSTRUCTIONS - Part A must be completed by an officer of the corporation who is authorized to sign the corporation’s return or report before the ERO trans-
mits the electronically filed Form NYC-2A (Combined Business Corporation Tax Return); NYC-2 (Business Corporation Tax Return); NYC-2S (Business Corporation Tax 
Return); NYC-EXT (Application for 6-month Extension to File Business Income Tax Return); NYC-EXT.1 (Application for Additional Extension); NYC-300 (Mandatory First 
Installment (MFI) by Business C Corporations) or NYC-400 (Declaration of Estimated Tax by Business Corporations and Subchapter S General Corporations).  
 
EROs/paid preparers must complete Part B prior to transmitting electronically filed corporation tax returns or reports (Forms NYC-2, NYC-2A, NYC-2S, NYC-EXT, 
NYC-EXT.1, NYC-300 or NYC-400).  Both the paid preparer and the ERO are required to sign Part B.  However, if an individual performs as both the paid preparer and 
the ERO, he or she is only required to sign as the paid preparer.  It is not necessary to include the ERO signature in this case. 
 
Do not mail Form NYC-579-COR to the Department of Finance. The EROs/paid preparers must keep the completed Form NYC-579-COR for three years from the due 
date of the return or report or the date the return or report was filed, whichever is later, and must present it to the Department of Finance upon request.
                                                                                                                                                           NYC-579-COR   2020
