For a copy of the recorded certificate, you must contact the recording office where the Certificate of Release of Federal Tax Lien was filed. If the federal tax lien has not been released within 30 days of satisfying your tax liability, you can request a Certificate of Release of Federal Tax Lien.
Proper handling of the notice of lien is extremely important. Generally the IRS can pursue collection of a tax liability up to 10 years from the date it was assessed. A Notice of Federal Tax Lien may be filed any time within that 10-year period.
