An Internal Revenue Service (IRS) customer service number is a telephone number that taxpayers can call to speak with an IRS representative about their tax questions or issues.
The IRS customer service number is a valuable resource for taxpayers who need assistance with their taxes. Representatives can help taxpayers with a variety of tasks, such as filing their taxes, making payments, and understanding their tax obligations. The IRS has a long history of providing customer service to taxpayers. The first IRS customer service number was established in 1913.
