of the transmission, (b) an indication of any refund offset, (c) the reason for any delay in processing the return or refund, and

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
