Global Interest

Global Interest Netting can save substantial amounts of interest for your company by determining if there is an under/over payment interest from corporate income, excise tax, or employment tax that can be claimed from the IRS.

Account Analysis

Retaining CIS to conduct an Account Analysis could allow your company to recover interest from years you had no idea was available to claim by giving you an updated interest calculation of the interest that may be due.

Interest Recovery Review

An Interest Recovery Review will help to ensure that your company is getting the most interest owed to you from the IRS, and our methodology will result in the most favorable outcome for your company in income tax recovery.


We will retrieve transcripts with detailed account information from the IRS for the taxpayer that may go back 20 years or more. We use our combined knowledge to perform a comprehensive account analysis that determines the proper amount of interest your company should have paid or should receive back from the IRS. Once the analysis is completed, we will present our findings in a claim for a refund that is acceptable to the IRS and then we will defend it, should the IRS disagree with the findings.
