The OECD promotes better policies for better lives in countries of all income levels. It works with public and private partners around the world to improve sustainable development outcomes, and encourage more effective, transparent development co-operation and financing.

Taxation is central to building strong, prosperous and inclusive societies by helping to raise the revenues needed to deliver much needed public goods and services. The OECD produces internationally comparable tax data, analysis and policy advice with the aim of helping governments around the world to design and implement effective, fair and efficient tax systems to foster resilient, inclusive and sustainable growth over the long term.
