Updated October 21, 2026. Quick answer: The MainePERS State Member Handbook says the cost-of-living adjustment (COLA) starts in September after a retiree has been paid for at least 12 months if the Normal Retirement Age is 60, or the first September at least 12 months after reaching Normal Retirement Age if it is 62 or 65. It matches the Consumer Price Index for all Urban Consumers, there is no COLA when the CPI is negative, and it applies to the first $20,000 of the retirement benefit (indexed).
What this covers
The handbook’s heading is “Cost-of-Living Adjustment (COLA)”. It sits in the part on other service retirement provisions and gives the timing rule by Normal Retirement Age, the index it follows and the part of the benefit it applies to. This page follows that paragraph and quotes it.
For the wider set of MainePERS choices, see MainePERS retirement decisions and public pension retirement decisions.
Who it applies to
It applies to a retired state employee member, and the starting date turns on the member’s Normal Retirement Age (NRA), which the handbook sets by plan. The table below follows the handbook’s order.
The rules, one by one
Each right-hand cell is language from the handbook paragraph.
| Question | What the handbook says |
|---|---|
| Normal Retirement Age 60 | “If your Normal Retirement Age (NRA) is 60, you are eligible to receive any COLA after you have received retirement benefit payments for at least 12 months.” |
| When it begins at NRA 60 | “Your COLA begins the September after you meet this requirement.” |
| The handbook’s example | “if your retirement date is on or before September 1 of any year, you will receive any COLA effective in September of the following year.” |
| Normal Retirement Age 62 or 65 | “you will receive any COLA effective the first September that is at least 12 months after you reach your normal retirement age.” |
| What it tracks | “The Cost of Living adjustment matches the Consumer Price Index for all Urban Consumers (CPI-U)” |
| When prices fall | “When the CPI is negative, there will be no COLA.” |
| How much of the benefit | “COLA is applicable to the first $20,000 of your retirement benefit (indexed).” |
What the handbook does not say
The paragraph prints no yearly percentage, because the adjustment follows the index. It also does not say what the base is indexed to or how it is rounded, and the handbook marks the base with the word “(indexed)”. Ask MainePERS for the current figures before planning around a COLA.
Edition
This page reads the MainePERS State Member Handbook as the Maine Public Employees Retirement System served it on 2026-10-21. It speaks to state employee members; teachers, legislators, judges and local-district employees can have different provisions, and the plan documents control over this summary. The state tax treatment of the pension itself is on whether Maine taxes pensions.
Common mistakes
- Expecting a COLA in the first year of retirement. At age 60 the handbook requires “at least 12 months” of payments first.
- Assuming the COLA applies to the whole benefit. The handbook says “COLA is applicable to the first $20,000 of your retirement benefit (indexed).”
- Assuming prices only go up. The handbook says “When the CPI is negative, there will be no COLA.”
