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 › § 1313
Defines three key words used in this part: "determination," "taxpayer," and "related taxpayer." Determination means one of four things: a final decision by the Tax Court or any court; a closing agreement under section 7121; the Secretary’s final handling of a refund claim (items allowed are final on the refund date or on the mailing date of a disallowance because of offsets; items denied are final when the time to sue ends unless suit is filed earlier); or an agreement signed by the Secretary and a person under rules the Secretary makes. Even if section 7701(a)(14) says otherwise, taxpayer here means any person subject to a tax under the relevant revenue law. Related taxpayer means someone who, in the same tax year, had one of these ties to the taxpayer: husband or wife; grantor and fiduciary; grantor and beneficiary; fiduciary and beneficiary, legatee, or heir; decedent and the decedent’s estate; partner; or a member of an affiliated group of corporations (see section 1504).
