An IRS demand letter is a letter sent by the Internal Revenue Service (IRS) to inform a taxpayer of an outstanding tax debt that needs to be paid.

The IRS demand to furnish information letter will typically outline the amount owed, the reasons for the debt, and the steps the taxpayer needs to take to resolve the issue.
