FRS Tier 1 vs Tier 2: Retirement Age, Vesting, and AFC Differences

The July 1, 2011 Dividing Line

Your FRS tier depends entirely on when you were first enrolled in the Florida Retirement System. If your initial enrollment was before July 1, 2011, you're Tier I. If it was on or after that date, you're Tier II. Breaks in employment don't change your tier — what matters is the original enrollment date.

This single date controls five things about your retirement: when you can retire without penalty, how long you must work to vest, how many salary years count in your benefit calculation, whether you receive a cost-of-living adjustment, and how much your early retirement penalty subtracts from each year you retire early.

Normal Retirement Age

Regular Class Tier I: Age 62 when vested (6 years; if you vest later, normal retirement begins when you vest), or 30 years of service at any age.

Regular Class Tier II: Age 65 when vested (8 years; if you vest later, normal retirement begins when you vest), or 33 years of service at any age.

Special Risk Tier I: Age 55 once vested in Special Risk service (6 years; if you vest after age 55, normal retirement begins when you vest); 25 years of Special Risk service regardless of age; or age 52 with 25 years of creditable service, including up to 4 years of eligible military service credit not claimed under another system, with the remaining years in the Special Risk Class.

Special Risk Tier II: Age 55 once vested in Special Risk service (8 years; if you vest after age 55, normal retirement begins when you vest); 25 years of Special Risk service regardless of age; or age 52 with 25 years of creditable service, including up to 4 years of eligible military service credit not claimed under another system, with the remaining years in the Special Risk Class. Tier II members who terminated employment before July 1, 2023 remain subject to the prior rules: age 60 once vested (8 years), 30 years of Special Risk service regardless of age, or age 57 with 30 years of creditable service, including up to 4 years of military credit not claimed under another system and the remaining years in the Special Risk Class.

Vesting

Tier I members vest after 6 years of creditable service. Tier II members vest after 8 years. Until you vest, you have no right to a defined benefit pension from employer contributions — only a refund of your personal 3% employee contributions.

Average Final Compensation

This is where the tier difference hits hardest financially. AFC is the average of your highest-earning fiscal years (July 1 through June 30):

• Tier I: Highest 5 fiscal years
• Tier II: Highest 8 fiscal years

Because Tier II averages over more years, it dilutes the impact of late-career raises. A Tier I member who gets a significant promotion in their last five years captures it fully in their AFC. A Tier II member's AFC includes three additional lower-earning years that pull the average down.

Includable earnings for both tiers: base salary, shift differentials, compulsory overtime, and annual leave payouts up to 500 hours. Excluded for both: sick leave payouts, terminal bonuses, and payments made after termination.

Cost-of-Living Adjustment

Tier I: A prorated COLA calculated as (pre-July 2011 years ÷ total years) × 3.0%. If all your service was before July 2011, you get the full 3% annual adjustment. If you have 20 years pre-2011 and 5 years post-2011, your COLA is (20 ÷ 25) × 3.0% = 2.4%.

Tier II: 0% COLA for service earned after July 2011. Special Risk Tier II members receive a minimum 1.50% COLA under post-2026 legislation, but Regular Class Tier II members get nothing.

Over a 25-year retirement, the cumulative effect of a 3% COLA versus 0% is substantial. A $2,500 monthly benefit grows to over $5,200 with 3% annual adjustments. Without COLA, it stays at $2,500 while inflation erodes its purchasing power every year.

Early Retirement Penalty

Both tiers apply the same 5% benefit reduction per year you retire before normal retirement age. A Tier I Regular Class member retiring at 59 (three years before age 62) takes a permanent 15% cut. A Tier II member retiring at 62 (three years before age 65) takes the same 15% reduction.

The penalty is calculated on your full benefit amount and applies for life — there's no catch-up once you reach the normal retirement age.
