IRS & Taxes

The Internal Revenue Service (IRS) is the branch of the Department of the Treasury that collects federal taxes. The IRS website is an informative resource if you have questions regarding tax matters. 

If you have already contacted the IRS and still not resolved your concern, please fill out the online form at the bottom of this page. Once you have submitted the form,  you will be prompted to print, sign, and return a privacy release form to the Dallas office. Constituent caseworkers will initiate a congressional inquiry on your behalf with the IRS in an effort to resolve your problem. A thorough review of your case will be conducted and responded to in accordance with federal law.

If you are writing on behalf of a company or organization, please include your Federal Tax Employer Identification Number in lieu of your Social Security number.

If your issue is time-sensitive, please call the Dallas office at 972-239-1310.

Internal Revenue Service provides comprehensive information for individuals, businesses, nonprofits, tax professionals, and others. It also offers several online services such as finding a Free File provider, finding an authorized IRS e-file provider, and checking on your refund. You can also download any IRS form or publication from their website.

Taxpayer Advocate Service (TAS)

The Taxpayer Advocate Service (TAS) is an independent organization within the IRS and is responsible for representing the taxpayers’ voice within the IRS. The agency’s mission is to provide assistance to taxpayers whose problems are not resolved through normal IRS channels. The TAS website offers a comprehensive toolkit to help taxpayers, including interactive tax assistance, tax videos, frequently asked questions, and links to other resources.

If you are experiencing a problem dealing with the IRS or would suffer a significant hardship as a result of the administration of tax law, you can contact the Taxpayer Advocate Service for assistance.

Please contact the TAS office that is geographically closest to your permanent residence.

A significant hardship is a situation where an action by the IRS, if taken, would prevent a taxpayer from providing for basic necessities such as housing, food, utilities and transportation, or for a business taxpayer to meet basic expenses such as payroll.

If you are suffering significant hardship as a result of the administration of tax law, you may file a Form 911, Application for Taxpayer Assistance Order, with the Taxpayer Advocate Service. Taxpayer Assistance Orders allow the Taxpayer Advocate to intervene, review the facts and circumstances of the case, and take the appropriate steps allowed by law to relieve the taxpayer’s hardship.

You may also call or visit a local IRS office for assistance with your concern. The IRS has offices throughout Texas where you can meet with an agency representative. If you would like to visit an office, call the nearest IRS office to schedule an appointment. 

If you are still seeking further information or assistance, please contact Senator Cornyn’s Dallas office at 972-239-1310.
