8.1.1. General Rule. IRS’ ability to collect any federal tax expires 10 years after it assesses the tax, unless it commences a lawsuit to collect, obtains a favorable court judgment and periodically renews the judgment. IRC § 6502.
The 10 year statute of limitations also applies to tax liens. A federal tax lien will expire 10 years after the tax is assessed, unless IRS begins a lawsuit to collect, obtains a favorable court judgment, and periodically renews the judgment.
Facts. Taxpayer owes unpaid employment taxes (both the employer and employee portions) for the 2004 tax year. The unpaid tax was assessed on September 15, 2005. IRS files a tax lien five years later on September 15, 2010.
Result. Taxpayer can never discharge the employee portion of the tax in bankruptcy. However, the tax will become uncollectible, and the lien will expire, unless IRS files suit to collect the tax on or before September 15, 2015, 10 years after the tax was assessed.
(a) Court Proceedings. IRC § 6503(a)(1) suspends the limitations period for any time period during which IRS is prohibited from collecting a tax by levy or a proceeding in court, and for 60 days thereafter.
(b) Bankruptcy Filings. IRC § 6503(h) suspends the limitations period during any time which the IRS is prohibited from collecting due to a bankruptcy proceeding, and for 6 months thereafter.

● No Return Filed. The Taxpayer never filed a required tax return for the tax in question.
