As of July 2015, the IRS contact number for individuals is 800-829-1040. The IRS website lists additional telephone numbers for businesses, exempt organizations, retirement plan administrators, identity theft victims and hearing impaired individuals.
Phone call wait times can be lengthy as call volumes increase dramatically during tax season. Additionally, the range of topics covered over the phone is limited. For assisting with more difficult questions, the IRS operates local offices at which individuals can take advantage of face-to-face consultations. A listing of those offices and in-depth information on a host of tax topics also can be found on the IRS website.
