Government revenue
Government revenue comes mainly from royalties on non-renewable natural resources (30.4%), personal income taxes (22.3%), corporate and other taxes (19.6%), and grants from the federal government primarily for infrastructure projects (9.8%). Albertans are the lowest-taxed people in Canada, and Alberta is the only province in Canada without a provincial sales tax (but residents are still subject to the federal sales tax, the Goods and Services Tax of 5%). It is also the only Canadian province to have a flat tax for personal income taxes, which is 10% of taxable income.
