Corporate Social Responsibility (CSR) has become a major source of funding for Non-Governmental Organizations (NGOs) in India. Many companies allocate a portion of their profits to social welfare activities such as education, healthcare, environmental protection, rural development, and poverty alleviation. However, NGOs cannot directly receive CSR funds unless they complete CSR-1 registration with the Government of India. CSR-1 registration allows NGOs to officially act as implementing agencies for corporate CSR projects. This guide explains the complete CSR-1 registration process, eligibility criteria, required documents, benefits, and compliance requirements for NGOs seeking CSR funding.
