Virtual Help
Need help but don’t have a local Taxpayer Advocate Service office near you? We have a new option! TAS now offers virtual help through video conferencing.  

How does this work?
You can go to the location listed below and use high-definition two-way video conferencing to get face-to-face help from a taxpayer advocate in another city.  Similar to talking to a case advocate in person, this allows you to discuss your tax matters in a private setting.

The Taxpayer Advocate Service is your voice at the IRS. Our job is to ensure that every taxpayer is treated fairly, and that you know and understand your rights. We offer free help to guide you through the often-confusing process of resolving tax problems that you haven’t been able to solve on your own. Remember, the worst thing you can do is nothing at all.

TAS can help if you can’t resolve your problem with the IRS and:

  • Your problem is causing financial difficulties for you, your family, or your business.
  • You face (or your business is facing) an immediate threat of adverse action.
  • You’ve tried repeatedly to contact the IRS but no one has responded to you, or the IRS hasn’t responded by the date promised.

If you qualify for our help, we’ll do everything we can to get your problem resolved. You'll be assigned to one advocate who will be with you at every turn. Although TAS is independent within the IRS, our advocates know how to work with the IRS to get your problems resolved.

As a taxpayer, you have rights that the IRS must abide by in its dealings with you. Our tax toolkit can help you understand these rights.
