Claim of right doctrine
In the tax law of the United States the claim of right doctrine causes a taxpayer to recognize income if they receive the income even though they do not have a fixed right to the income. For the income to qualify as being received there must be a receipt of cash or property that ordinarily constitutes income rather than loans or gifts or deposits that are returnable, the taxpayer needs unlimited control on the use or disposition of the funds, and the taxpayer must hold and treat the income as its own.
