For most cases, employing the assistance of an Enrolled Agent will help you resolve your tax related issues. Make sure you meet with your EA and disclose everything so that they can choose the right method of resolution.
However, if an acceptable resolution cannot be found, you may contact the Taxpayer Advocate Service (TAS). Be aware that your EA can reach out to this agency on your behalf, if needed. This service allows you to speak with an advocate to assist you with the tax issue you may be having. Please note that every state has a local TAS office. There’s also a TAS office in Washington, D.C. and Puerto Rico.
To address any tax dispute with a Taxpayer Advocate, it must fall into one of the following categories:
1) You must have already tried repeatedly to contact the IRS to resolve the problem.
2) The agency did not get back to you as promised.
3) The regular IRS channels of communication did not work.
4) You are experiencing substantial tax-related hardship and financial problems.
