Treasury Regulations, Subchapter A, Sec. 1.6015(e)-1

From TaxAlmanac

In the making of a declaration of estimated tax, the taxpayer is required to take into account the then existing facts and circumstances as well as those reasonably to be anticipated relating to prospective gross income, allowable deductions, and estimated credits for the taxable year. Amended or revised declarations may be made in any case in which the taxpayer estimates that his gross income, deductions, or credits will differ from the gross income, deductions, or credits reflected in the previous declaration. An amended declaration may also be made based upon a change in the number of exemptions to which the taxpayer may be entitled for the then current taxable year. However, only one amended declaration may be filed during any interval between installment dates. See paragraph (d) of §1.6073–1. An amended declaration may be filed jointly by husband and wife even though separate declarations have previously been filed. An amended declaration may be made on either Form 1040–ES (marked “Amended”). See, however, paragraph (c) of §1.6015(d)–1 for procedure to be followed if the prescribed form is not available.
