Notice of federal tax lien

A notice of federal tax lien is the public filing that establishes the government's claim against a taxpayer's property for an unpaid assessed tax, filed after a demand for payment goes unpaid.

How it works

The lien itself arises automatically when tax is assessed and unpaid after demand. The notice of federal tax lien is the public filing that makes it visible to lenders, buyers, and credit reports, and it can be appealed within 30 days. The lien attaches to all property, including property acquired later. It is released when the debt is paid or the collection statute expires, and it can be withdrawn after a direct debit installment agreement on balances of 25,000 dollars or less, subordinated, or discharged from specific property.

Why it matters

Withdrawal and discharge are available in more cases than most taxpayers realize, and a filed lien is often the obstacle to refinancing or selling.
