Part II  Declaration and Signature Authorization of Officer (Be sure to get a copy of the corporation’s return)

Under penalties of perjury, I declare that I am an officer of the above corporation and that I have examined a copy of the corporation’s 
2020 electronic income tax return and accompanying schedules and statements and to the best of my knowledge and belief, it is true, 
correct, and complete. I further declare that the amounts in Part I above are the amounts shown on the copy of the corporation’s

send the corporation’s return to the IRS and to receive from the IRS (a) an acknowledgement of receipt or reason for rejection of the 
transmission, (b) the reason for any delay in processing the return or refund, and (c) the date of any refund. If applicable, 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. I have selected a personal identification number (PIN) as my signature for the corporation’s electronic
