Amends the Employee Retirement Income Security Act of 1974 to prohibit the decrease of any employee welfare benefits (currently, only pension benefits) of a participant by reason of any increase in the levels of Social Security or railroad retirement benefits.

Amends the Internal Revenue Code to deny an employer any income tax deduction for amounts paid to or under a disability compensation plan if the benefits payable to an individual under such plan are reduced, or any scheduled increase in such benefits is omitted, on account of any increase in monthly insurance benefits to which such an individual is entitled under title II of the Social Security Act (Old Age, Survivors, and Disability Insurance).
