As a separate legal entity, a corporation must submit a tax return each year with
the IRS. For corporations with a fiscal year ending December 31, tax returns are
due on March 15. A corporation must file a tax return even if it does not have income
or no tax is due. C corporations file tax returns on Form 1120 or 1120A.
Although S corporations do not pay federal taxes at the corporate level, they still
must prepare a separate tax return (Form 1120S).
For 2008, the federal income tax rate for a C corporation is as follows:
Income

Up to $50,000

From $50,000 to $75,000

Some states, including California, also have a state corporate income tax. Corporations
that anticipate a tax liability of $500 or more must estimate their taxes and make
quarterly estimated tax payments. Corporations with employees are required to pay
federal (and sometimes state) payroll and unemployment taxes.
