Adjusted Limits

The Internal Revenue Service has announced the 2006 adjusted limits that affect the operation of tax-qualified retirement plans, including 401(k) plans, and certain other types of employee benefit plans. Please see the accompanying table for these new adjusted limits, effective January 1, 2006.

Social Security

The Social Security (OASDI) taxable wage base, which governs the amount of pay subject to Social Security tax withholding and affects plans that are "integrated" with Social Security, also is adjusted annually. For 2006, the wage base has been increased to $94,200. The Medicare tax, however, applies to all wages without limit.
