Working after a CalSTRS retirement

You can go back to work in California public schools. Two rules decide how much it costs your pension: the first 180 days, and the yearly earnings limit.

California specificsShort answer: for the first 180 days after you retire, what you earn in California public schools cuts your benefit dollar for dollar; after that you can earn up to $80,245 in 2025-26 before benefits are withheld. If you'd rather keep earning service, compare one more year. Health coverage after you leave is on retiree health. Check the benefit at stake in the calculator.
Rule 1

The first 180 days

During the first 180 calendar days after your most recent retirement date, your monthly retirement and Defined Benefit Supplement benefits are reduced dollar for dollar by what you earn performing retired member activities in the California public school system (including employer contributions to tax-sheltered annuities), up to the benefit payable in that period. Those earnings also count against the annual limit.

Handbook p. 91, Separation-from-service requirement
Rule 2

$80,245 a year (2025-26)

Earnings above the limit are collected by withholding all gross monthly benefits until the excess is collected, up to the annual retirement benefit minus any separation-from-service reduction. 2026-27 limit: Working After Retirement fact sheet / CalSTRS.com/limits.

Handbook p. 92, Postretirement earnings limit
Worked example (handbook)A retiree earns $90,000 in 2025-26. That's $9,755 over the $80,245 limit, so $9,755 is withheld from benefits.Handbook p. 92, Postretirement earnings limit

The handbook gives the 2025-26 pay caps and earnings limit only. Newer figures are posted by CalSTRS.

We use the 2025-26 figures.

p. 122, Compensation cap under IRC and California Education Code

The exemption to the 180 days

Narrow exemption: you are at normal retirement age (60 for 2% at 60, 62 for 2% at 62) when the pay is earned, the appointment fills a critically needed position, you got no financial inducement to retire, your termination did not cause the need, and (from July 1, 2024) the employer had no reduction-in-force layoff in the prior 18 months. The employer must submit documentation before you start. Handbook p. 91, Separation-from-service requirement

Other limits

Going back to work for real: reinstating

You may terminate retirement and reinstate at any time. Re-retiring within one year: you must keep the same option and beneficiaries. You must earn at least one year of service credit after reinstating before you qualify for disability or survivor benefits. You lose retirement incentive service credit. Handbook p. 94, Reinstating to active member status

Under two years back: RicardoFewer than two years of new service: new benefit = the monthly benefit you were eligible for before reinstatement, increased by the 2% annual adjustments that would have applied, plus an amount based on service since reinstatement, age at the new retirement and final compensation. Ricardo's $2,500 benefit grows to $2,650 with the yearly 2% adjustments. His new year at a 2% age factor on $6,000 adds $120. Total: $2,770 a month.Handbook p. 95, How your benefit will be calculated if you reinstate
Two years or more back: MichelleTwo or more years of new service: the amount based on service before your last retirement, an adjusted age factor and your highest final compensation, plus an amount for the new service; compared with the fewer-than-two-years method, and you receive the higher. Michelle: 20 earlier years at a 1.76% adjusted age factor ($2,112) plus 3 new years at 2.4% ($432) = $2,544 a month.Handbook p. 96, Reinstate for two years or more
Not explained in the handbook Check with CalSTRS

For members who return to work for two years or more, the handbook uses an 'adjusted age factor' but doesn't explain how it's worked out.

We don't estimate this case.

Questions

Can I substitute teach after retiring from CalSTRS?

Yes, with limits. In the first 180 days after you retire, any pay for retired-member work in California public schools, including substitute teaching, reduces your benefit dollar for dollar, with a narrow exemption. After that, an annual earnings limit applies ($80,245 for 2025-26).

What happens if I earn more than the limit?

CalSTRS takes back the amount over the limit by withholding your monthly benefit until it's collected, up to your annual benefit.
