Part II  Taxpayer Declaration and Signature Authorization (Be sure you get and keep a copy of your return)
Under penalties of perjury, I declare that I have examined a copy of the income tax return (original or amended) I am now authorizing, 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 from the income tax 
return (original or amended) I am now authorizing. I consent to allow my intermediate service provider, transmitter, or electronic return originator (ERO) 
to send my 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 ACH electronic funds withdrawal (direct debit) entry to the financial institution account indicated in the tax preparation software for 
payment of my federal taxes owed on this return and/or a payment of estimated tax, and the financial institution to debit the entry to this account. This 
authorization is to remain in full force and effect until I notify the U.S. Treasury Financial Agent to terminate the authorization. To revoke (cancel) a 
payment, I must contact the U.S. Treasury Financial Agent at    1-888-353-4537. Payment cancellation requests must be received 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 further acknowledge that the 
personal identification number (PIN) below is my signature for the income tax return (original or amended) I am now authorizing and, if applicable, my 
Electronic Funds Withdrawal Consent.
