Under penalties of perjury, I declare that I have examined a copy of my electronic application for extension of time to file for the tax year ending December 

31, 2006, and to the best of my knowledge and belief, it is true, correct, and complete. I further declare that the information listed above is the information

(ERO) to send this form to the IRS and to receive from the IRS (a) an acknowledgement of receipt or reason for rejection of the transmission and (b) the

reason for any delay in processing the form. 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, 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 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

Revenue Code requires taxpayers to sign

their tax returns or other documents.

Section 6061(b) permits the IRS to accept

your electronic signature for your application

for an extension of time to file, and for you

to authorize an electronic return originator

(ERO) to enter or generate the PIN on your

behalf. You are not required to authorize

your ERO to enter your PIN as your

signature on your behalf; you may personally

enter your PIN at the time of transmission or

include giving it to the Department of

Justice for use in civil and criminal litigation,

and to cities, states, and the District of

Columbia for use in administering their tax

laws. We may also disclose this information

to other countries under a tax treaty, to

federal and state agencies to enforce federal

nontax criminal laws, or to federal law

enforcement and intelligence agencies to

combat terrorism. Providing false or

fraudulent information may subject you to

penalties.

You are not required to provide the

information requested on a form that is

subject to the Paperwork Reduction Act

unless the form displays a valid OMB

control number. Books or records relating

to a form or its instructions must be

become material in the administration of

any Internal Revenue law. Generally, tax

returns and return information are

confidential, as required by Internal

Revenue Code section 6103.

The average time and expenses required

to complete and file this form will vary

depending on individual circumstances. For

the estimated averages, see the
