"[A 20%] excise tax is imposed on employer reversions [of assets] from a 'qualified plan,' defined ... as a plan that is qualified under Code Sec. 401(a) or Code Sec. 403(a), 'other than ... a plan maintained by an employer if such employer has, at all times, been exempt from tax under subtitle A[.]' ... The IRS maintained that the plan was a 'qualified plan' [and hence subject to the excise tax despite the aforesaid exemption for tax-exempt employers] because the taxpayer had paid unrelated business income tax, which is a tax under Subtitle A, for certain years.... The court held that the employer was an organization that had, at all times, been exempt from tax under Subtitle A. Thus, the employer's pension plan was not ... liable for the Code Sec. 4980 excise tax."  MORE >>
