Bills introduced in the Parliament are of two kinds:

1. Public bills (or government bills)
2. Private bills (also called private members’ bills)

Though both are governed by the same general procedure and pass through the same stages in the House but differ in few aspects. 

The bills introduced in the Parliament can also be classified into four categories as mentioned below:

1. Ordinary bills – These bills are concerned with any matter other than financial subjects.
2. Money bills –  These bills are concerned with financial matters like taxation, public expenditure, etc.,
3. Financial bills – These bills are also concerned with financial matters (but are different from money bills).
4. Constitutional amendment bills – These bills are concerned with the amendment of the provisions of the Constitution.
