The Constitution exempts educational and social assistance NPOs from taxes on their revenues, assets, and services. In order to be eligible, the NPO cannot distribute profits and must demonstrate, through valid accounting records, that all of its expenditures were related to its statutory aims. These requirements mean that such organizations are closer in status to  organizations in the US.
Organizations that do not qualify for constitutional tax exemptions may still be eligible for tax exemptions granted by law at the federal, state, and municipal levels.
Further, NPOs may receive tax deductible grants from corporate donors. Individuals cannot make tax-deductible donations directly to NPOs, but may donate to projects developed by NPOs to benefit specific groups, such as children and the elderly, or in specific fields, such as culture and sports.
