IRS Audits or Examinations


If you are facing an audit by the IRS (Internal Revenue Service), you have the right to attorney representation. You have the right to work with a legal professional who will provide you with answers to your questions, actively protect your rights, and provide documentation to the IRS. You may be unsure of why you are being audited in the first place or may be certain that you have done nothing wrong. Hiring an experienced Oklahoma City IRS audit lawyer is an important step to take regardless of the circumstances of your audit if you would like the greatest opportunity of closing your audit as quickly and to the best result possible. Our team is familiar with the IRS audit process and can review your unique case to determine exactly what the IRS may be after. We can then protect your interests to the fullest extent of the law.


Representation for IRS Tax Audits in Oklahoma City and Tulsa


Your first and only line of defense against an IRS audit is a tax law attorney at Th Trevillion Law Firm, PC. Our firm handles IRS tax audits for taxpayers in Oklahoma City, Tulsa and throughout all of Oklahoma City. In handling an audit for a client, we will first ensure we have the Information Document Request from the IRS. The IRS files this document to inform you of exactly what information they need to see. We will work with you to assemble the necessary documentation requested. From here, we will handle all communication with the IRS. Investigators and auditors would like nothing more than unlimited access to a taxpayer who is not represented by an attorney. We know what to do and what to say in order to ensure that your rights are not violated in the audit process.


With our skilled counsel, we can limit the consequences that an IRS audit may have on you from a financial and legal standpoint.
