Sec. 2-11. Direct return and payment by self-assessing purchaser. When  electricity is used or consumed by a self-assessing purchaser subject to the  tax imposed by this Law who did not pay the tax to a delivering supplier  maintaining a place of business within this State and required or authorized  to collect the tax, that self-assessing purchaser shall, on or before the 15th  day of each month, make a return to the Department for the preceding calendar  month, stating all of the following:(1) The self-assessing purchaser's name and principal     address.(2) The aggregate purchase price paid by the     self-assessing purchaser for the distribution, supply, furnishing, sale, transmission and delivery of such electricity to or for the purchaser during the preceding calendar month, including budget plan and other purchaser-owned amounts applied during such month in payment of charges includible in the purchase price, and upon the basis of which the tax is imposed.(3) Amount of tax, computed upon item (2) at the rate     stated in Section 2-4.(4) Such other information as the Department     reasonably may require.In making such return the self-assessing purchaser may  use any reasonable method to derive reportable "purchase price"  from the self-assessing purchaser's  records.If the average monthly tax liability of the self-assessing  purchaser to the Department does not exceed $2,500,  the Department may authorize the self-assessing purchaser's  returns to be filed on a quarter-annual basis, with the return  for January, February and March of a given year being due by  April 30 of such year; with the return for April, May and June  of a given year being due by July 31 of such year; with the  return for July, August, and September of a given year being  due by October 31 of such year; and with the return for  October, November and December of a given year being due by  January 31 of the following year.If the average monthly tax liability of the self-assessing  purchaser to the Department does not exceed $1,000, the  Department may authorize the self-assessing purchaser's  returns to be filed on an annual basis, with the return for a  given year being due by January 31 of the following year.Such quarter-annual and annual returns, as to form and  substance, shall be subject to the same requirements as  monthly returns.Notwithstanding any other provision in this Law  concerning the time within which a self-assessing purchaser  may file a return, any such self-assessing purchaser who  ceases to be responsible for filing returns under this Law  shall file a final return under this Law with the Department  not more than one month thereafter.Each self-assessing purchaser whose average monthly  liability to the Department pursuant to this Section was  $10,000 or more during the preceding calendar year, excluding  the month of highest liability and the month of lowest  liability during such calendar year, and which is not operated  by a unit of local government, shall make estimated payments  to the Department on or before the 7th, 15th, 22nd and last  day of the month during which tax liability to the Department  is incurred in an amount not less than the lower of either  22.5% of such self-assessing purchaser's actual tax liability  for the month or 25% of such self-assessing purchaser's actual  tax liability for the same calendar month of the preceding  year.  The amount of such quarter-monthly payments shall be  credited against the final tax liability of the self-assessing  purchaser's return for that month.  An outstanding credit  approved by the Department or a credit memorandum  issued by the Department arising from the self-assessing  purchaser's overpayment of the self-assessing purchaser's  final tax liability for any month may be applied to reduce the  amount of any subsequent quarter-monthly payment or credited  against the final tax liability of such self-assessing  purchaser's return for any subsequent month.  If any  quarter-monthly payment is not paid at the time or in the amount  required by this Section, such person shall be liable for  penalty and interest on the difference between the minimum  amount due as a payment and the amount of such payment  actually and timely paid, except insofar as such person has  previously made payments for that month to the Department in  excess of the minimum payments previously due.If the Director finds that the information required for  the making of an accurate return cannot reasonably be compiled  by a self-assessing purchaser within 15 days after the close  of the calendar month for which a return is to be made, the  Director may grant an extension of time for the filing of such  return for a period of not to exceed 31 calendar days.  The  granting of such an extension may be conditioned upon the  deposit by such self-assessing purchaser with the Department  of an amount of money not exceeding the amount estimated by  the Director to be due with the return so extended.  All such  deposits shall be credited against such self-assessing  purchaser's liabilities under this Law.  If the deposit  exceeds such self-assessing purchaser's present and probable  future liabilities under this Law, the Department shall issue  to such self-assessing purchaser a credit memorandum, which  may be assigned by such self-assessing purchaser to a similar  person under this Law, in accordance with reasonable rules and  regulations to be prescribed by the Department.The self-assessing purchaser making the return provided  for in this Section shall, at the time of making such return,  pay to the Department the amount of tax imposed by this Law.Until October 1, 2002, a self-assessing purchaser who has an average  monthly tax  liability of $10,000 or more shall make all payments  required by rules of the Department by electronic funds  transfer.  The term "average monthly tax liability" shall be  the sum of the self-assessing purchaser's liabilities under  this Law for the immediately preceding calendar year divided  by 12.  Beginning on October 1, 2002, a taxpayer who has a tax liability in the  amount set forth in subsection (b) of Section 2505-210 of the Department of  Revenue Law shall make all payments required by rules of the Department by  electronic funds transfer.  Any self-assessing purchaser not required to make  payments by electronic funds transfer may make payments by  electronic funds transfer with the permission of the  Department.  All self-assessing purchasers required to make  payments by electronic funds transfer and any self-assessing  purchasers authorized to voluntarily make payments by  electronic funds transfer shall make those payments in the  manner authorized by the Department.If any payment provided for in this Section exceeds the self-assessing purchaser's liabilities under this Act, as shown on an original return, the Department may authorize the self-assessing purchaser to credit such excess payment against liability subsequently to be remitted to the Department under this Act, in accordance with reasonable rules adopted by the Department.Through June 30, 2004, each month the Department shall pay into the Public  Utility Fund in the State treasury an amount determined by the  Director to be equal to 3.0% of the funds received by  the Department pursuant to this Section.  Through June 30, 2004, the remainder of all  moneys received by the Department under this Section shall be  paid into the General Revenue Fund in the State treasury. Beginning on July 1, 2004, of the 3% of the funds received pursuant to this Section, each month the Department shall pay $416,667 into the General Revenue Fund and the balance shall be paid into the Public Utility Fund in the State treasury.
