IPERS and Social Security

IPERS (the Iowa Public Employees' Retirement System) is built to add to Social Security, not replace it. You pay Social Security tax on your IPERS wages.

Iowa specificsShort answer: yes, Iowa teachers in IPERS pay Social Security tax, and IPERS is built to add to Social Security. The two meet in two places: Regular disability benefits require a Social Security disability award, and the return-to-work limit before 65 is $50,000 or Social Security's limit, if higher (see working after retirement). Estimate your IPERS benefit in the calculator and check taxes.

What IPERS says

IPERS contributions are subject to FICA (the Social Security tax). IPERS is designed to supplement Social Security and personal savings. Member Handbook (2025), p. 12, Pretax Contributions; p. 3, Introduction; p. 9, IPERS' Role in Your Retirement Planning

Member contributions are tax-deferred for federal income tax (since Jan. 1, 1995) and Iowa income tax (since Jan. 1, 1999), but are subject to FICA. Member Handbook (2025), p. 12, Pretax Contributions

Working after retirement

IPERS's return-to-work earnings limit before 65 is $50,000 a calendar year or the Social Security annual earnings limit, whichever is higher. Member Handbook (2025), pp. 52-53, Earnings Restrictions

The Social Security earnings limit Check with IPERS

The return-to-work limit is $50,000 or the Social Security earnings limit, whichever is higher. Our sources don't give this year's Social Security figure.

We use $50,000. If the Social Security limit is higher this year, the higher figure applies.

What would settle it: SSA's current annual exempt amount for people under full retirement age.

Your Social Security benefit

IPERS's publications don't estimate Social Security. Get your own estimate from the Social Security Administration (ssa.gov), and add it to your IPERS estimate from the calculator.
