Social Security Wage Base Set to Increase for 2005; New Law Regarding Employees Not Covered by Social Security

As the designated liaison between the Social Security Administration and employers with Social Security Section 218 Agreements, the Department of Employee Trust Funds provides the following updated information including Social Security and Medicare wage bases for 2005. This information applies to all Wisconsin Retirement System employers and all other public employers subject to a Social Security Section 218 agreement.

  • Social Security and Medicare Wage Bases and Rates for 2005

    Effective for all wages paid on or after January 1, 2005, the Social Security (full FICA) wage base will increase from $87,900 to $90,000. The Medicare wage base will not have a dollar limit for 2005.

    Although the wage base will increase, the employer and employee tax rates will remain the same in 2005. The Social Security (full FICA) rate remains at 7.65% (6.20% Social Security plus 1.45% Medicare) for wages up to $90,000. All wages over $90,000 are subject only to the 1.45% Medicare rate. The rate remains at 1.45% for others who are subject only to Medicare.

  • Earnings Exemptions for 2005

    The maximum amount a Social Security beneficiary between the ages of 62 through 64 may earn without any reduction in benefits will increase to $12,000 per year ($1,000 a month). An increased earnings limit will then apply beginning January 1 following the calendar year during which the individual turned 64 and will remain in effect through the end of the month in which the individual turns 65 years and 4 months. The maximum earnings amount prior to turning 65 years and 4 months, without any reduction, is $31,800 per year or $2,650 a month. There is no limit on earnings beginning the month after the individual attains age 65 years and 4 months.

New Law Regarding Employees Not Covered by Social Security

Section 419(c) of Public Law 108-203, the Social Security Protection Act of 2004, requires State and local government employers to disclose the effect of the Windfall Elimination Provision and the Government Pension Offset to employees hired on or after January 1, 2005, in jobs not covered by Social Security. The law requires newly hired public employees to sign a statement that they are aware of a possible reduction in their future Social Security benefit entitlement.
