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
2018 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
electronic income tax return. I consent to allow my electronic return originator (ERO), transmitter, or intermediate service provider to
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
income tax return and, if applicable, the corporation’s consent to electronic funds withdrawal.
