How much federal taxes due on 2500.00 in Illinois?

If the 2500 is income from an employer and you are an employee and will receive a W-2 form for the 2500 amount and you do not have any other worldwide income to be reported on your federal 1040 tax return then you would not have any federal income tax liability for the tax year 2009 when you file the 2009 income tax return in the year 2010.
