An Association of Persons (AOP) and a Body of Individuals (BOI) convey two different arrangements of people. The fact that both of these expressions at times are used interchangeably doesn’t justify the restrictive interpretation. We need to stop interchanging the usage of these words as they represent two different compositions.

The Indian Income Tax Act, 1961, defines AOP (Association of Persons) as an integration of persons for a mutual benefit or a common purpose. On the other hand, BOI (Body of individuals) is similar to an AOP and is also an accumulation of individuals who have come together with an objective of earning some income. However, there are certain differences between an Association of Persons and Body of Individuals

. A person in AOP could be a company or an individual person. The term person could include any association, body of individuals or company, irrespective of whether it is incorporated or not. However, in a BOI, only individuals can join with the intention of earning some income. Hence we can say, BOI only comprises of individuals, whereas an AOP could include legal entities.

In a nutshell, it could be said that an AOP (association of persons) has a legal meaning and it represents a unit having duties and rights. For instance, if a group of people are travelling in a train, or waiting for a bus at the bus stop, they might be a group of people or in the literal sense a “body of individuals”. However, they’re not an AOP (association of persons) in a legal sense.

Moreover, an AOP implies a combination of persons which doesn’t mean that any combination or group of persons is an AOP. It’s only when these individuals associate themselves with any income-producing activity they can be called an AOP.
