Sources of non-tax revenue
- Aid from another level of government (intragovernmental aid) - for example, in the United States, federal grants may be considered non-tax revenue to the receiving states, and equalization payments
- Aid from abroad (foreign aid)
- Tribute or indemnities paid by a weaker state to a stronger one, often as a condition of peace after suffering military defeat. The war reparations paid by the defeated Central Powers after the First World War offer a well-known example.
- Revenue (including interest or profit) from investment funds (collective investment schemes), sovereign wealth funds, or endowments
- Revenues from sales of state assets
- Rents, concessions, and royalties collected by the state when it contracts out the right to profit from some good or service to a private corporation. An example are contracts for resource extraction (for such natural resources as minerals, timber, petroleum and natural gas, or marine resources) collected privately under license from state-owned lands
- Fines collected and assets forfeitured as a penalty. Examples include parking fines, court costs levied on criminal offenders
- Fees for the granting or issuance of permits or licenses. Examples include vehicle registration plate permits, vehicle registration fees, watercraft registration fees, building fees, driver's licenses, hunting and fishing licenses, fees for professional licensing, fees for visas or passports, fees for demolition, rezoning, and land grading (which causes silt), and sometimes for increasing stormwater runoff, destroying native vegetation, and cutting-down healthy trees.
- User fees collected in exchange for the use of many public services and facilities. Tolls charged for the use of toll roads are an example
- Donations and voluntary contributions to the state
