Generally if the IRS does not identify a substantial error, then the IRS can audit tax returns filed in the last three years and the States can typically audit four years. Audits can be complex, time-consuming, and stressful. Having a professional and expert team is highly recommended, even if you feel confident in your ability to handle the process. CPA CLINICS’ Tax Audit Representation services alleviate the burden by providing expert guidance and support during the Federal, State, or Local audit.
