Six months If you file for an extension on your individual tax return, the IRS will give you six more months to complete the return. The IRS changed the extensions in 2006. There is now only the option for 6-month extensions (it used to be that you would file one extension, and could then file a second one for a total of 6 months).
Generally an IRS tax lien will automatically release 10 years (from the date of assessment) after it was filed. However, the IRS may re-file liens under certain circumstances. So the key date is ten years from the date of the final notice and assessment of tax due for the tax year in question. If subsequently, you have not been notified that the tax lien was re-filed you should request a Certificate of Release of Federal Tax Lien. IRS Publication 1450 can give you specific instructions on how to do this. See it at http://www.irs.gov/pub/irs-pdf/p1450.pdf.
