Corporate tax is imposed in the United States at the Federal, most state, and some local levels on the income of entities treated for tax purposes as corporations. Federal tax rates on corporate taxable income vary from 15% to 35%. State and local taxes and rules vary by jurisdiction, though many are based on Federal concepts and definitions. Taxable income may differ from book income both as to timing of income and tax deductions and as to what is taxable. Corporations are also subject to a Federal Alternative Minimum Tax and alternative state taxes. Like individuals, corporations must file tax returns every year.
