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 › § 1311
If an error listed in section 1312 cannot be fixed right away because another law or legal rule stops it, the IRS must fix the effect of that error later by making an adjustment in the amount and way described in section 1314. The IRS can only make that adjustment if certain conditions are met. Except for the special cases in section 1312(3)(B) and 1312(4), an adjustment is allowed only when there is an inconsistent position adopted in the determination: if the adjustment would give a refund or credit, the IRS must have taken the opposite position; if the adjustment would lead to extra tax being assessed and collected, the taxpayer must have taken the opposite position. For a case under section 1312(3)(B) (certain income exclusions), the adjustment is allowed only if a deficiency assessment for that year was not barred when the IRS first argued inclusion in a notice of deficiency or before the Tax Court. For a case under section 1312(4) (disallowed deductions or credits), the adjustment is allowed only if a refund or credit was not barred when the taxpayer first wrote to the IRS or the Tax Court claiming the deduction or credit. When the adjustment would be collected like a deficiency (except for 1312(3)(B) cases), it cannot be applied to a related taxpayer unless that relationship existed when the original inconsistent position was first taken in a return, refund claim, or Tax Court petition, or if there was none, at the time of the determination.
