Under penalties of perjury, I declare that I am a general partner or limited liability company member manager of the above partnership 

and that I have examined a copy of the partnership’s 2012 electronic income tax return and accompanying schedules and statements 

and to the best of my knowledge and belief, they are true, correct, and complete. I further declare that the amounts in Part I above are

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 

partnership’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 before 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 partnership’s electronic income tax return and, if applicable, the partnership’s consent to electronic
