In today’s economy, your stockholders, private investors and creditors often need verification that your corporate financial statements represent an accurate snapshot of the financial position of your company.  An independent audit provides the highest level of assurance a CPA can offer through an objective examination of financial reports. By submitting to an independent audit, you will confirm to interested parties that your financial position is fairly stated. Additionally, audits facilitate the purchase and sale of a business as well as comply with any banking covenants. 

If your business is a not-for-profit agency or a government organization you are most likely required by Illinois law to undergo an annual audit. Please contact us to schedule your audit and to keep you compliant with this fiduciary responsibility.
