This notice is necessary to conform the present value factors to changes in the economic and demographic assumptions adopted by the Board of Actuaries of the Civil Service Retirement System. ## Effects PRIA read - New Present Value Tables Published: mixed, medium. OPM published updated present value factor tables that will be used when converting lump sums into lifetime annuity reductions. The new tables (for example: age 40 = 388.8; age 65 = 214.7; age 100 = 26.2; ages 17–39 are listed separately) take effect for annuities or computations on or after Octobe… - Alternative Form of Annuity Recalculations: mixed, medium. If you are a CSRS retiree who elects an alternative form of annuity under 5 U.S.C. 8343a, OPM will use the revised present value factors to compute the actuarial reduction for annuities that commence on or after October 1, 2026. The revised computation method is required by 5 CFR 831.2205(a). - Redeposit Calculations for Pre-1991 Service: mixed, medium. If you owe a redeposit for refunded service that ended before March 1, 1991 under 5 U.S.C. 8334(d)(2), OPM will use the revised present value factors to compute the reduction to complete payment for annuities that commence on or after October 1, 2026. This follows 5 CFR 831.303(c). - Post-Retirement Marriage Survivor Reductions: mixed, medium. If you are a CSRS retiree who elects to provide a survivor annuity based on a post-retirement marriage under 5 U.S.C. 8339(j) or (k), OPM will apply the revised present value factors to establish the permanent actuarial reduction starting for survivor reductions that commence on or after October 1,… - Nonappropriated Fund Service Credit Costs: mixed, medium. If you elect to credit service with nonappropriated fund instrumentalities under 5 U.S.C. 8347(q) to qualify for immediate CSRS retirement, OPM will use the revised present value factors to compute the deficiency you must pay when the date of computation under 5 CFR 847.603 or 847.809 is on or afte… - FERCCA Coverage-Error Reductions Updated: mixed, medium. For retirees and survivors affected by erroneous retirement coverage corrections under FERCCA, OPM will use the revised present value factors to compute actuarial reductions for unpaid service credit deposits, Government Thrift Savings Plan contributions, or prior payment of the FERS Basic Employee… ## Related documents - [2026-19222](https://policyrisk.com/federal-register/2026-19222): Employment in the Excepted Service, 2026-09-18 - [2026-18828](https://policyrisk.com/federal-register/2026-18828): Shared Certificates and Pooled Hiring Actions, 2026-09-15 - [2026-18800](https://policyrisk.com/federal-register/2026-18800): Reduction in Force; Correction, 2026-09-15 - [2026-16687](https://policyrisk.com/federal-register/2026-16687): Differential Pay for Prescribed Wildland Fire Activities, 2026-08-14 - [2026-15650](https://policyrisk.com/federal-register/2026-15650): Suitability Action Appeals, 2026-08-03 - [2026-15666](https://policyrisk.com/federal-register/2026-15666): Reduction in Force Appeals, 2026-08-03 ## Sources - [2026-12584 on federalregister.gov](https://www.federalregister.gov/documents/2026/06/23/2026-12584/civil-service-retirement-system-present-value-factors) - [2026-12584 as published (PDF)](https://www.govinfo.gov/content/pkg/FR-2026-06-23/pdf/2026-12584.pdf) ## Related - [Previous: 2026-12583, Federal Employees' Retirement System; Normal Cost Percentages](https://policyrisk.com/federal-register/2026-12583) - [Next: 2026-12585, Submission for OMB Review; 30-Day Comment Request; Chimpanzee Research Use Form…](https://policyrisk.com/federal-register/2026-12585) - [All Federal Register documents](https://policyrisk.com/federal-register) Source: PRIA, https://policyrisk.com/federal-register/2026-12584 (as of 2026-06-30).
