The leakage that the Government sector provides is through the collection of revenue through taxes (T) that is provided by households and firms to the government. This is a leakage because it is a leakage out of the current income thus reducing the expenditure on current goods and services. The injection provided by the government sector is government spending (G) that provides collective services and welfare payments to the community. An example of a tax collected by the government as a leakage is income tax and an injection into the economy can be when the government redistributes this income in the form of welfare payments, that is a form of government spending back into the economy.
