§ 1.6152-1 Installment payments.

(a) Privilege of corporation to elect to make installment payments--(1) Amount to be paid.  In the case of any taxable year ending on or after December 31, 1954, a corporation subject to the taxes imposed by chapter 1 of the Code may elect, as provided in subparagraph (2) of this paragraph, to pay the unpaid amount of such tax for the taxable year in two equal installments instead of making a single payment.  If such an election is made, the installments shall be paid as follows:

(i) Fifty percent on or before the date prescribed for the payment of the tax as a single payment, and

(ii) The remaining 50 percent on or before three months after the date prescribed for the payment of the first installment.

For provisions relating to installment payments of estimated income tax by corporations, see section 6154 and §§ 1.6154-1 to 1.6154-3, inclusive.

(2) Method of election.  A corporation shall be considered to have made an election to pay its tax in installments if:

(i) It files its income tax return on or before the date prescribed therefor  (determined without regard to any extension of time) and pays 50 percent of the unpaid amount of the tax at such time, or

(ii) It files an application on Form 7004 for an automatic extension of time to file its income tax return, as provided in § 1.6081-3, and pays 50 percent of the unpaid amount of the tax at such time.  Except as provided in paragraph (c) of this section, the installment privilege is limited to the unpaid amount of tax as shown on the income tax return filed in accordance with the provisions of subdivision (i) of this subparagraph, or as shown on the Form 7004 filed in accordance with the provisions of this subdivision.

(3) Use of Government depositaries.  For provisions relating to the use of Federal Reserve banks and authorized financial institutions in depositing the taxes see § 1.6302-1.

(b) Privilege of estates of decedents to make installment payments.  With respect to the income tax imposed by chapter 1 of the Code upon estates of decedents, the fiduciary may elect to pay the tax in four equal installments instead of in a single payment.  If the election is made, the tax shall be paid as follows:

(1) Twenty-five percent on or before the date prescribed for the payment of the tax as a single payment,

(2) Twenty-five percent on or before three months after the date prescribed for payment of the first installment,

(3) Twenty-five percent on or before six months after the date prescribed for payment of the first installment, and

(4) Twenty-five percent on or before nine months after the date prescribed for payment of the first installment.

(c) Proration of deficiency to installments.  If an election has been made to pay the tax imposed by chapter 1 of the Code in installments, and a deficiency has been assessed, the deficiency shall be prorated equally to all the installments, whether paid or unpaid.  Except as provided in section 6861, relating to jeopardy assessment, the part of the deficiency so prorated to any installment which is not yet due shall be collected at the same time as and as part of such installment.  The part of the deficiency so prorated to any installment the date for payment of which has arrived shall be paid upon notice and demand from the district director.

(d) Acceleration of payment.  If a taxpayer elects under the provisions of this section to pay the tax in installments, any installment may be paid prior to the date prescribed for its payment.  If an installment is not paid in full on or before the date fixed for its payment the whole amount of the unpaid tax shall be paid upon notice and demand from the district director.
