Updated October 30, 2026. Quick answer: Tennessee TCRS Hybrid Plan members (state employees, certain higher education employees and teachers hired after June 30, 2014 who have not kept Legacy Plan membership from earlier service) are eligible for unreduced service retirement at age 65 with five years of creditable service or at the Rule of 90, and for reduced early retirement at age 60 with five years or the Rule of 80. Legacy Plan members hired before July 1, 2014 (unless they lost Legacy membership) are eligible for unreduced retirement at age 60 or with 30 years, and for early retirement at age 55 or with 25 years; for a member age 55 or older with 10 or more years, the reduction is 0.4% for each month. The Hybrid Plan has a five-year vesting requirement.
Hybrid Plan: unreduced retirement
“Full-time state employees, certain higher education employees, and public school teachers hired after June 30, 2014 are members of the Hybrid Retirement Plan for State Employees and Teachers (“Hybrid Plan”) as a condition of employment if they have not maintained membership in the TCRS Legacy Pension Plan based on previous service as a state employee, higher education employee or teacher prior to July 1, 2014.” “A member becomes eligible for unreduced service retirement benefits upon attainment of age 65 and completion of five years of creditable service or reaching the Rule of 90.” “The Rule of 90 means the attainment of a combination of age and years of creditable service as to equal 90.”
Hybrid Plan: early retirement
The July 2014 TCRS Hybrid FAQ says: “A member must now attain age 60 and 5 years of creditable service or meet the Rule of 80 (where age and years of service total 80).” A summary sheet from the University of Tennessee’s Municipal Technical Advisory Service adds: “Earlier retirement permitted at age 60 or Rule of 80, at a reduced benefit using the full, unsubsidized actuarial discount factors.”
Hybrid Plan: vesting
“After meeting the five-year vesting requirement, a member becomes eligible to receive a monthly retirement benefit upon reaching the age and/or service requirement to begin benefits.”
Legacy Plan
“Full-time state employees and certain higher education employees hired prior to July 1, 2014 are members of the TCRS Defined Benefit Legacy Plan (“Legacy Plan”) as a condition of employment unless the employee lost membership in the Legacy Plan.” “A vested member who has 30 years of creditable service or is at least age 60, is eligible for an unreduced service retirement benefit.” “A vested member who is at least age 55 or has 25 years of creditable service is eligible to start receiving Early Retirement benefits before reaching Service Retirement eligibility.” “For Members age 55 or older with 10 or More Years of Service: The Early Retirement benefit is calculated the same way as the Service Retirement benefit, but with a permanent reduction of 0.4% for each month that the retirement date precedes the date the member would qualify for Service Retirement.”
What the pension is based on
Hybrid, per the TCRS FAQ: “The benefit accrual factor is 1% under the Hybrid Pension Plan versus 1.5% under the Legacy Pension Plan.” The Hybrid guide defines the average: “The AFC is the average of the member’s five highest consecutive years (60 consecutive months) of earnable compensation.” Legacy: “Tennessee state law provides a benefit accrual factor for the Legacy Plan equal to 1.5% of AFC for each year of creditable service.”
A worked example with invented numbers
Take an invented Hybrid Plan member with 30 years of creditable service. That is 30 years at 1%, or 30% (computed) of a final average salary of $60,000 (invented, for the computation), which comes to $18,000 a year (computed).
Now take an invented Legacy Plan member with 30 years of creditable service. That is 30 years at 1.5%, or 45% (computed) of a final average salary of $60,000 (invented, for the computation), which comes to $27,000 a year (computed).
What the documents do not say
The Hybrid early retirement reduction is described only as a reduced benefit using actuarial discount factors, with no per-month rate in the documents read; the early-retirement and accrual-factor sentences come from a July 2014 TCRS FAQ and a University of Tennessee summary sheet because the 2024 Hybrid guide could not be read in order by every text extractor. The Legacy guide scopes the 0.4% monthly reduction to members age 55 or older with 10 or more years of service; the reduction for early retirement before age 55 with 25 years is not quoted in full. Local-government TCRS employers, public safety officers, judges and General Assembly members are not covered, and the Legacy guide read is for state and higher education employees, not teachers.
Common mistakes
- Reading 90 as an age. The Rule of 90 means age and years of creditable service add up to 90.
- Applying the Legacy Plan’s 30-year route to a Hybrid member. The Hybrid Plan uses age 65 with five years or the Rule of 90.
- Assuming this page covers local-government members. Their plans were not read for this page.
