 nature on the New York City electronically filed Application for an Extension to File a Return and/or 2021 Declaration of Estimated Tax. If I am paying the New York 
 City banking corporation tax owed by electronic funds withdrawal, I authorize the New York City Department of Finance and its designated financial agents to ini-
 tiate an electronic funds withdrawal from the financial institution account indicated on the banking corporation’s 2020 New York City electronically filed Application 
 for an Extension to File a Return and/or 2021 Declaration of Estimated Tax, and I authorize the financial institution to debit the amount from that account.

 PURPOSE - A completed Form NYC-579-BCT provides documentation that an ERO has been authorized to electronically file Form(s) NYC-EXT, NYC-EXT.1 and/or NYC-
 400B. The officer of the corporation who is authorized to sign the corporationʼs returns may designate the ERO to electronically sign the Form(s) NYC-EXT, NYC-EXT.1 
 and/or NYC-400B, by entering the officerʼs personal identification number (PIN). The form also authorizes payment of tax due on an electronically submitted return or re-
 port 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 NYC-EXT (Application for 6-month Extension to File Business Income Tax Return); or NYC-EXT.1 (Application for Additional Extension); or 
 NYC-400B  (Declaration of Estimated Tax) 
 EROs/paid preparers must complete Part B prior to transmitting an electronically filed Application for an Extension to File a Return (Forms NYC-EXT or NYC-EXT.1) or Dec-
 laration of Estimated Tax (NYC-400B).  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-BCT to the Department of TheFinance.EROs/paid preparers must keep the completed Form NYC-579-BCT 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.
