As of November 2015, the contact phone number for individuals to receive tax assistance is 800-829-1040, and the contact phone number for businesses is 800-829-4933, reports the Internal Revenue Service. On the IRS.gov website, the IRS also lists contact phone numbers for individuals with hearing impairments, victims of identity theft, retirement plan administrators, government entities and exempt organizations. Telephone assistance is available Monday through Friday from 7 a.m. to 7 p.m. local time.
When individuals call the IRS for tax assistance, they first encounter recorded messages that help them navigate through menus in English or Spanish, explains About.com. If they are persistent, they obtain a connection with live IRS personnel. During tax season, taxpayers sometimes must wait a long time to talk to a tax agent. If the call volume is high, they can opt for a callback option that allows them to hang up and await a call when their turn comes.
IRS personnel can handle only a limited amount of topics by phone, and once taxpayers hang up, they cannot get back in touch with the original agent who answered their call, according to the IRS. Online at IRS.gov, taxpayers can find answers to many tax questions, set up payment plans, make payments and track their refunds. The IRS communicates with taxpayers via paper mail and does not usually phone them, warns About.com. Phone calls purportedly from the IRS demanding personal or financial information are probably scams.
