Sec.  1.6154-5  Definition of estimated tax.

    For taxable years beginning after December 31, 1976, the term 
estimated tax means the excess of--
    (a) The amount which the corporation estimates as its income tax 
liability for the taxable year under section 11 or 1201(a), or 
subchapter L of chapter 1 of the Code, whichever is applicable, over
    (b) The sum of--
    (1) Any estimated credits against tax provided by part IV of 
subchapter A of chapter 1 of the Code, plus
    (2) For taxable years ending after February 29, 1980, the amount 
which the corporation estimates will be the amount of such corporation's 
overpayment of windfall profit tax imposed by section 4986 of the Code 
for the taxable year. For this purpose, the amount of such overpayment 
is the amount by which such corporation's aggregate windfall profit tax 
liability for the taxable year as a producer of crude oil is reasonably 
expected to be exceeded by withholding of windfall profit tax for the 
taxable year.
