CPA CLINICS' Tax Resolution Services can assist in determining eligibility of an OIC and preparing and submitting the documentation. The eligibility factors include ability to pay, income, expenses, and asset equity. We will calculate the reasonable collection potential, complete Form 656, mail your completed Form 656, and negotiate with the tax authority. This is a lengthy process and may from several months to over a year to complete; therefore, our Tax Resolution Services Team stays in regular communication with the tax authority to help expedite the process.
