An IRS tax lien is a legal claim against a taxpayer's property that arises when they fail to pay their tax debts owed to the IRS. When a taxpayer owes back taxes, the IRS can place a lien on their assets, which serves as a public declaration that the IRS has a right to the taxpayer's property as security for the tax debt. This lien can encompass real estate, personal property, and financial accounts, thereby affecting the taxpayer's credit score and ability to sell or refinance assets until the tax debt is settled.

The description of a tax lien captures its essential function as a tool for the IRS to ensure compliance with tax obligations and to recover owed funds. Other options provided, such as a notice of financial tax obligation, a penalty for late tax filing, or a deduction for business expenses, do not accurately represent the nature of a tax lien. A lien represents the government's claim against an individual's property rather than merely indicating that taxes are due or related to other tax concepts like penalties or deductions.
