 Many Non-Profit organizations need to have an audit for the Illinois Attorney General along with the IL AG990 tax form.  Effective 2009 the IRS has changed the 990 and 990T tax forms.  501(c) 3 charities of any size must now file an annual tax return, even if they had little or no activity. John Pezzullo has attended the IRS and Illinois CPA society training sessions on these new forms and requirements which are effective for the current tax year.  Jonlyn & Associates can provide the necessary compliant financial statements, reports and tax returns.  The audit, if required for your Illinois AG 990, is usually done separately from your corporate audit, so we can work with your current CPA firm.
