Four account types, set by entry date
TRS sorts members by the date they entered the system. The account type sets your multiplier, your retirement ages and your early retirement penalty. The rules here come from KRS 161.600 and 161.620 and the TRS Service Retirement bulletins. They cover nonuniversity members: teachers and staff of school districts and state agencies. University members have lower multipliers because they also pay into Social Security.
- TRS 1: entered before July 1, 2002
- TRS 2: entered July 1, 2002 to June 30, 2008
- TRS 3: entered July 1, 2008 to Dec. 31, 2021
- TRS 4: entered on or after Jan. 1, 2022
Annual Benefit = Service Credit x Multiplier x Final Average Salary
TRS 1 and TRS 2: 2.5% a year
If you entered before July 1, 2008, every year up to 30 earns 2.5% of FAS. Years above 30 earn 3%. Two exceptions: service before July 1, 1983 stays at 2%, and a TRS 2 member who retires with fewer than 10 years gets 2% on all of it. At 10.0 years, TRS 2 moves to 2.5% on every year.
A TRS 1 member with 20 years and a $60,000 FAS gets 2.5% x 20 x $60,000 = $30,000 a year, $2,500 a month. With 33 years: 2.5% x 30 x $60,000 plus 3% x 3 x $60,000 = $50,400. The annuity can't exceed your FAS or your last year's salary, whichever is greater.
TRS 3: the stepped multiplier
Members who entered from July 2008 through 2021 earn a multiplier that rises with total service. Once you cross a line, every year converts to the higher rate, up to 30 years.
10 years or less: 1.7% | 10.01 to 20: 2.0% | 20.01 to 26: 2.3% | 26.01 to 30: 2.5% | each year above 30: 3%
The same 20 years and $60,000 FAS gives a TRS 3 member 2% x 20 x $60,000 = $24,000, which is $6,000 a year less than TRS 1. At 27 years the gap closes: 2.5% x 27 x $60,000 = $40,500 for both.
TRS 4: age factor plus career factor
Members who entered on or after Jan. 1, 2022 get a foundational annuity and a supplemental account. The foundational multiplier adds two pieces. The age factor is 1.7% through age 60 and climbs monthly to 1.9% at 65. The career factor is 0.25% once you have 20 years and 0.5% at 30. The result applies to every year, so the range is 1.7% to 2.4%. FAS is your 5 highest salaries. A TRS 4 member retiring at 57 with 30 years and a $60,000 FAS gets 2.2% x 30 x $60,000 = $39,600. The supplemental account is paid on top and isn't in this estimate.
KRS 161.633 lets the TRS board change the TRS 4 factors, ages and COLA if the foundational plan falls below its funding target. Check the current TRS 4 bulletin before you rely on these numbers.
When you can retire
TRS 1, 2 and 3 retire unreduced with 27 years at any age, or at 60 with 5 years. Earlier retirement starts at 55, with 5 years for TRS 1 and 2 and 10 years for TRS 3. The cut is 5% a year (TRS 1-2) or 6% a year (TRS 3) for each year you're under 60 or under 27 years of service, whichever number is smaller. A TRS 1 member at 57 with 25 years is 3 years under 60 and 2 years short of 27, so the cut is 2 x 5% = 10%.
TRS 4 retires unreduced at 65 with 5 years, at 60 with 10, or at 57 with 30. From 57 with 10 years you can go early, losing 6% a year for each year under 60 or under 30 years, whichever is smaller. The most you can lose is 18%.
Age eligibility starts on the first of the month after your birthday, and all TRS retirements start on the first of a month.
The 1.5% COLA
Every July 1, KRS 161.620(2) raises each retiree's allowance by 1.5%. The raise builds on the prior year's amount, and it's prorated if you retired less than 12 months earlier. A $30,000 annuity grows to about $34,820 after 10 COLAs and $40,410 after 20. For TRS 4, the board can adjust the COLA on the foundational benefit.
Social Security and taxes
Kentucky school district teachers don't pay into Social Security for TRS-covered work. The TRS annuity is meant to replace it. If you earned Social Security elsewhere, the WEP and GPO repeal in January 2025 means it's no longer cut because of your TRS pension.
Kentucky taxes only the part of the annuity earned by service after Jan. 1, 1998, and only above the $31,110 pension exclusion.

Frequently asked questions
How is a Kentucky TRS pension calculated?
Service credit x multiplier x final average salary. The multiplier depends on your account type. TRS 1 (entered before July 1, 2002) gets 2.5% a year, with service before July 1, 1983 at 2%. TRS 2 (July 1, 2002 to June 30, 2008) gets 2% with fewer than 10 years and 2.5% on everything from 10 years on. TRS 3 (July 1, 2008 to Dec. 31, 2021) steps from 1.7% to 2.5% as service grows, and the rate you reach applies to all years up to 30. TRS 1-3 earn 3% for each year above 30. A TRS 1 member with 20 years and a $60,000 FAS gets $30,000 a year. A TRS 3 member with the same numbers gets $24,000.
What are the TRS 3 multipliers?
1.7% with 10 or fewer years, 2% above 10 through 20, 2.3% above 20 through 26, and 2.5% above 26 through 30. When you cross into a higher band, every year converts to it. Years above 30 earn 3%.
How does TRS 4 work?
Members who entered on or after Jan. 1, 2022 get a foundational annuity plus a supplemental savings account. The foundational multiplier is an age factor (1.7% up to 60, rising monthly to 1.9% at 65) plus a career factor (0.25% at 20 to 29.99 years, 0.5% at 30 or more), so it runs from 1.7% to 2.4%. FAS is the 5 highest salaries. The board can adjust these factors and the COLA if funding falls below target.
What is the 27-year rule?
TRS 1, 2 and 3 members can retire unreduced at any age with 27 years of Kentucky service. They can also retire unreduced at 60 with 5 years. TRS 4 members don't have the 27-year rule: they need 65 with 5 years, 60 with 10, or 57 with 30.
Can I retire early from Kentucky TRS?
TRS 1 and 2 can retire at 55 with 5 years, reduced 5% for each year under 60 or under 27 years of service, whichever is less. TRS 3 can retire at 55 with 10 years, reduced 6% a year on the same test. TRS 4 can retire at 57 with 10 years, reduced 6% for each year under 60 or under 30 years, whichever is less, so the cut is at most 18%.
Does Kentucky TRS have a COLA?
Yes. KRS 161.620(2) adds 1.5% to every retiree's allowance each July 1. It compounds, and the first one is prorated if you've been retired less than a full year. For TRS 4 the board can adjust the COLA on the foundational benefit to keep the plan funded.
What final average salary does TRS use?
The average of your 5 highest annual salaries. TRS 1-3 members who retire at 55 or older with 27 years get the 3 highest instead. Raises in the last 3 years (last 5 for TRS 4) are limited to the increase generally available to your district's employees.
Do Kentucky teachers get Social Security?
Kentucky school district teachers in TRS don't pay into Social Security for that work, so the TRS annuity is their main retirement income from teaching. The federal WEP and GPO, which used to cut Social Security earned elsewhere, were repealed in January 2025. University members do pay into Social Security, which is why their multipliers are lower.
Is a Kentucky TRS pension taxed in Kentucky?
Only the part earned by service after Jan. 1, 1998 is taxable in Kentucky, and only after the pension exclusion of $31,110. Federal tax applies to the whole annuity.
