Title 5 › PART III — EMPLOYEES › Subpart G — Insurance and Annuities › CHAPTER 84 — FEDERAL EMPLOYEES’ RETIREMENT SYSTEM › SUBCHAPTER II — BASIC ANNUITY › § 8421a
If you get an annuity supplement and you earned extra money from work, your monthly supplement must be cut to account for those extra earnings. The cut is based on the previous year’s excess earnings, which are 50% of your pay that is above the exempt amount, but not more than the total supplement you received that prior year. That excess is spread evenly across your supplement months for the year (normally 12 months, but fewer if you stop getting the supplement because you reach age 62). No month’s reduction can be bigger than the supplement for that month. The reductions start in the 12‑month period that begins on the first day of the seventh month after the end of the calendar year when the extra earnings happened. “Earnings” and the “exempt amount” are figured like the Social Security rules. Only pay earned while you actually had the supplement counts. Pay earned before reaching your applicable retirement age is not counted for certain retirees. People working as FAA air traffic control instructors or as air traffic controllers under the specified contract rules are not covered by these reductions. The Office must make rules for reemployed annuitants.
