How do I contact the IRS?

Jim Buttonow, CPA, CITP

SVP Post-Filing Tax Services

Published on: July 08, 2021

You can contact the IRS by phone, mail, or walking in/making an appointment at a local Taxpayer Assistance Center. The IRS typically does not email taxpayers.

Most taxpayers contact the IRS by phone. The most common number to contact the IRS for individual taxpayers is (800) 829-1040. However, the IRS has specific hotlines dedicated to taxpayer issues. For example, if a taxpayer needs to contact IRS Collection, the phone numbers are (800) 829-3903 for individuals with small business/business entities and (800) 829-7650 for wage earners. 

It is sometimes very difficult to connect with the IRS by phone. In some cases, taxpayers can wait hours before talking to an IRS representative. Taxpayers may want to consider engaging and authorizing a Tax Pro who can use a special hotline (The Practitioner Priority Service) to get through to the IRS.

The IRS has over 150 hotlines to help taxpayers reach them.  Here are the most common hotlines and their hours of operation:
