ruling(redirected from Letters of Determination)
Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.
An official opinion by the IRS on how it interprets U.S. tax law. The IRS may make a ruling, for example, after seeing taxpayers apply a deduction or credit to an unusual, but still relevant situation. The IRS determines whether or not it will accept the situation, and, afterward, applies the ruling to all comparable situations. It is also called a revenue ruling, a letter ruling, or a private letter ruling.
