Phased Retirement
What is phased retirement and how does it work for employees and employers?
Phased retirement is an arrangement that allows employees approaching retirement age to gradually reduce their work hours while drawing partial retirement benefits, usually keeping some employment relationship and benefits eligibility. The federal government offers a formal Phased Retirement Program for federal employees. Private employers structure phased retirement informally through reduced schedules, part-time arrangements, or consulting roles. The arrangement helps both employees who want to ease into retirement and employers who want to retain institutional knowledge during transition.

Phased retirement addresses a real workforce reality: many late-career employees want to slow down rather than stop entirely, and many employers want to retain their expertise through the transition. The federal Phased Retirement Program formalizes the arrangement for federal civilian employees. In the private sector, phased retirement is more informal: reduced schedules, part-time arrangements, consulting agreements, or some combination. With the U.S. workforce aging (BLS projects 25% of workers age 55+ by 2030), interest in formal phased retirement options is growing.
Federal Phased Retirement Program
Federal civilian employees can elect phased retirement at age 55+ with at least 30 years of service (or age 60 with 20 years). They work 50% time and receive 50% retirement annuity plus 50% salary, with full benefits maintained. Mentorship of replacement employees is required.
Private Sector Phased Retirement Structures
Reduced full-time to part-time. Job sharing with another late-career employee. Consultant or contractor arrangement. Project-based work. Each has different benefits, tax, and ERISA implications.
Benefits and ERISA Considerations
Reducing hours can trigger benefits eligibility loss if the employee falls below full-time threshold. ERISA pension plans may have specific rules about partial benefit drawdowns. Health insurance and Medicare coordination becomes complex at age 65. See employee benefits for the eligibility framework.
Designing Phased Retirement That Works for Both Parties
Document the arrangement clearly. Maintain benefits eligibility where possible. Build in mentorship of successors. Coordinate with payroll for prorated pay and compensation structure. See exit interview for the eventual full transition.
