Title 26 › Subtitle 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
Sometimes a court decision or other final determination reveals a tax error in another year, but fixing that year is normally blocked, usually because the deadline has passed. These rules let the error be corrected anyway through an adjustment, in the amount and manner set by section 1314. There is a fairness condition: if the fix would give a refund, the determination must have adopted a position the IRS was arguing for; if the fix would collect more tax, it must have adopted a position the taxpayer was arguing for. Special timing rules apply when the error involves income left out of the right year or a disallowed deduction or credit, and adjustments against a related taxpayer require the relationship to exist at the right time.
