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 › § 1313
Defines three words used in this part: "determination," "taxpayer," and "related taxpayer." A "determination" means a final court decision or order, a closing agreement under section 7121, a final decision by the Secretary about a refund claim (items allowed are final when the refund is allowed or when notice of disallowance is mailed because of offsets; items disallowed are final when the time to sue runs out unless a suit is filed first), or an agreement signed by the Secretary and a person under rules the Secretary makes about that person’s tax liability. A "taxpayer" means any person who must pay a tax under the revenue law. A "related taxpayer" is someone who, in the tax year when the error occurred, had one of these relationships with the taxpayer: husband and wife; grantor and fiduciary; grantor and beneficiary; fiduciary and beneficiary, legatee, or heir; decedent and the decedent’s estate; partner; or member of an affiliated group of corporations (as defined in section 1504).
