# Assessee and Assessment
## Assessee [Sec 2(7)]
An Assessee means a person by whom any tax or any other sum of money is payable under the Income-tax Act, 1961.
The term also includes:
1. Every person in respect of whom any proceeding under the Act has been initiated for the assessment of:
- his income; OR
- the income of any other person for which he is assessable; OR
- the loss sustained by him or by such other person; OR
- the amount of refund due to him or to such other person.
2. Every person who is deemed to be an assessee under any provision of the Act.
3. Every person who is deemed to be an assessee in default under any provision of the Act (e.g., a deductor who fails to deduct/deposit TDS).
## Assessment
The procedure by which the income of an assessee is determined and tax liability is computed.
## Key Concept
> Every Assessee is a Person, but every Person is not an Assessee.
A person becomes an assessee only when there is a tax/sum payable, a proceeding initiated, or a deeming provision invoked.
