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
Fixing certain tax mistakes first requires a final "determination." That can be a final court decision, a closing agreement with the IRS, the IRS's final handling of a refund claim, or a special signed agreement between the IRS and a taxpayer. A refund claim counts as finally handled when the refund is allowed, when a disallowance notice is mailed, or when the time to sue over a denied claim runs out. A "taxpayer" here is anyone who owes tax under the law involved. A "related taxpayer" is someone closely connected to the person in the determination, such as a husband and wife, a grantor and a fiduciary or beneficiary, a fiduciary and a beneficiary or heir, a decedent and the decedent's estate, business partners, or companies in the same affiliated group.
