Period of holding rules for capital assets define conversion, declaration, and capital gains attribution treatment. The rule prescribes how the period of holding of capital assets is to be determined in specified cases, including conversion-related holdings, assets declared under the Income Declaration Scheme, 2016, and assets transferred to an Indian subsidiary on conversion of a foreign branch. It also provides that amounts taxed as income of a specified entity under the capital gains head are to be attributed to short-term capital assets in defined cases, and to long-term capital assets where the underlying asset is long-term and not covered by the short-term category.
