Back in the classroom, still drawing a TFFR pension

The rules for retirees of the North Dakota Teachers' Fund for Retirement (TFFR) who return to TFFR-covered work.

The general rule, the critical shortage exception and what happens if you go over are below; the glossary defines the terms. TFFR has no automatic COLA, so your pension stays flat while you work. Related: taxes and retiree health.

The general rule

After 30 days from the retirement date you may return to TFFR-covered work up to an annual hour limit (July 1-June 30) set by contract length, and keep your benefit. Member and employer contributions are paid on the salary; they add to your account value but do not change the benefit. Handbook pp. 26-28, Employment after retirement, General Rule; NDCC 15-39.1-19.1(1)

Not counted toward the limit: non-contracted substitute teaching, in-staff subbing, extracurricular duties, professional development. Handbook pp. 26-28, Employment after retirement, General Rule; NDCC 15-39.1-19.1(1)

The handbook's example: JaneJane retires July 1, 2025 and has a 9-month contract, so the limit is 700 hours a year. The handbook has Jane returning August 1, 2025. On our count, the 30 days end July 31, 2025. Handbook p. 28, Example (Jane)

Critical shortage areas

Exception A: in a critical shortage area or subject set each year by the Education Standards and Practices Board, you may exceed the hour limit and keep your benefit after a one-year wait (non-contracted subbing, extracurricular duties and professional development allowed during the wait). Re-apply each year. Handbook pp. 28-29, Exception A; NDCC 15-39.1-19.2

The handbook's example: JohnJohn retires July 1, 2024 and can return in a critical shortage area without an hour limit from July 1, 2025, one year later. Our engine gives July 1, 2025. Handbook pp. 28-29, Example (John)

Going over the limit

Exception B: after 30 days you may exceed the limit; the benefit stops the first of the month after you reach the limit. At re-retirement your benefit is the original benefit plus a benefit for the return-to-work period, with the same option. Handbook p. 29, Exception B; p. 30, At-A-Glance; NDCC 15-39.1-19.1(1)(g), (2)

Work the limits don't cover

Telling RIO

The employer must notify RIO within 30 days of the retiree's return, each year. Failure to notify and pay contributions costs the retiree one month's benefit and the employer a $250 penalty. No written pre-arranged re-employment agreement may exist at retirement. Handbook p. 27; NDCC 15-39.1-19.1(1)(c), (g); NDAC 82-05-06-01

Questions

How soon can I go back to teaching after I retire from TFFR?

After 30 days, under an annual hour limit, and you keep your benefit.

What are the hour limits?

700 hours for a 9-month contract, 800 hours for a 10-month contract, 900 hours for a 11-month contract, 1000 hours for a 12-month contract, for each July 1-June 30 year.

What if I teach in a critical shortage area?

After a 1-year wait from your retirement date, you can work past the hour limit and keep your benefit.

What if I go over the limit?

Under the general rule you can exceed it after 30 days, but your benefit stops the first of the month after you reach the limit.

Does substitute teaching count?

Non-contracted substitute teaching isn't limited. Contracted work for a TFFR employer is.
