MCA stands for Ministry of Corporate Affairs. It is the central government ministry responsible for administering the laws relating to companies, Limited Liability Partnerships (LLPs), and other related matters in India. The MCA is the apex regulatory body for corporate law — overseeing company incorporation, compliance, governance, insolvency, and the protection of investors and stakeholders.
Every company, LLP, or corporate entity doing business in India ultimately comes under the regulatory oversight of the MCA. From the moment a company is incorporated to the day it is wound up, the MCA’s framework governs its legal existence.

Key Legislation Administered by MCA
