Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter Q — Readjustment of Tax Between Years and Special Limitations › PART II — MITIGATION OF EFFECT OF LIMITATIONS AND OTHER PROVISIONS › § 1312
An adjustment is allowed when a later tax finding shows income, a deduction, or a credit was counted or missed in the wrong year or for a related taxpayer. This covers seven kinds of mistakes: the same income being included twice; the same deduction or credit being allowed twice; the same income being left out twice (whether it was on a return or not); a deduction or credit that should have been allowed but was denied twice; matching mistakes between estates or trusts and their beneficiaries; matching mistakes between related corporations; and errors in a property's tax basis because of a prior wrong treatment (for example, wrong income reporting, wrong gain or loss recognition, or treating an item as a capital item instead of a deductible expense, or vice versa).
