Article 243X of the Constitution of India empowers State Legislatures to authorize Municipalities to levy, collect, and utilize taxes, duties, tolls, and fees. Hence, Article 243X is the correct provision.
This Article also allows State Governments to assign certain revenues—such as taxes and duties collected by the State—to Municipalities for strengthening their financial resources. Additionally, it provides for grants-in-aid from the State’s Consolidated Fund to support municipal functions.
Further, Article 243X requires the creation of dedicated Municipal Funds where all receipts are credited and from which expenditures are made.
In contrast, Article 243P only defines key terms used in Part IX-A, such as Municipality, District, and Metropolitan area, and does not deal with financial powers. Hence, it is not relevant here.
Similarly, Article 243U deals with the tenure of Municipalities, fixing it at five years unless dissolved earlier, and does not address financial authority.
Lastly, Article 243ZB concerns the application of Part IX-A to Union Territories, allowing modifications by the President, and is unrelated to municipal financial powers.
