Part II     Declaration of Officer (see instructions) Be sure to keep a copy of the corporation’s tax return. 

6 a       I consent that the corporation’s refund be directly deposited as designated on the Form 8050, Direct Deposit of 
          Corporate Tax Refund, that will be electronically transmitted with the corporation’s 2020 federal income tax return. 
b         I do not want direct deposit of the corporation’s refund or the corporation is not receiving a refund. 
c         I authorize the U.S. Treasury and its designated Financial Agent to initiate an electronic funds withdrawal (direct debit)  
          entry to the financial institution account indicated in the tax preparation software for payment of the corporation’s federal 
          taxes owed on this return, and the financial institution to debit the entry to this account. To revoke a payment, I must 
          contact the U.S. Treasury Financial Agent at 1-888-353-4537 no later than 2 business days prior to the payment  
          (settlement) date. I also authorize the financial institutions involved in the processing of the electronic payment of taxes 
          to receive confidential information necessary to answer inquiries and resolve issues related to the payment. 
If the corporation is filing a balance due return, I understand that if the IRS does not receive full and timely payment of its tax  
liability, the corporation will remain liable for the tax liability and all applicable interest and penalties. 

Under penalties of perjury, I declare that I am an officer of the above corporation and that the information I have given my electronic return originator (ERO), transmitter,  
and/or intermediate service provider (ISP) and the amounts in Part I above agree with the amounts on the corresponding lines of the corporation’s 2020 federal income tax 
return. To the best of my knowledge and belief, the corporation’s return is true, correct, and complete. I consent to my ERO, transmitter, and/or ISP sending the  
corporation’s return, this declaration, and accompanying schedules and statements to the IRS. I also consent to the IRS sending my ERO, transmitter, and/or ISP an  
acknowledgment of receipt of transmission and an indication of whether or not the corporation’s return is accepted, and, if rejected,  the reason(s) for the rejection. If the 
processing of the corporation’s return or refund is delayed, I authorize the IRS to disclose to my ERO, transmitter, and/or ISP the  reason(s) for the delay, or when the refund 
was sent.
