NGOs are independent voluntary organizations that are distinct from government. They can be defined in various ways based on their orientation and level of operation, such as advocacy, development work, or capacity building at the local, national, or international level. In Pakistan, NGOs have the fundamental right to form associations under the constitution. They are typically registered as societies, trusts, or companies and are exempt from taxes as nonprofit organizations. Common types of NGOs include advocacy groups, research organizations, training providers, networking groups, large organizations that fund smaller partners, and community-based organizations.
