How Illinois Teachers Can Build Retirement Security Around TRS
Illinois educators face a complicated retirement landscape. The Teachers' Retirement System of the State of Illinois (TRS) is one of the most underfunded major state pensions, with funded ratios around 40–45%. While benefits remain legally protected, this makes a 403(b) supplement especially important.
The Funding Reality: Illinois TRS benefits are constitutionally protected, but decades of underfunding have created persistent fiscal stress. Prudent IL teachers should never rely solely on TRS.
Frequently Asked Questions5 questions
Is TRS alone enough for retirement in Illinois?
For most Illinois teachers, TRS replaces about 50–65% of final salary. Comfortable retirement typically requires 70–90%, so a 403(b) supplement closes that gap.
Are Illinois teachers covered by Social Security?
Generally NOT covered. This affects how much you should contribute to a 403(b) — uncovered teachers should generally save more.
Can I contribute to a 403(b) and an IRA?
Yes — they have separate limits ($23,000 for 403(b) and $7,000 for IRA in 2026, with catch-up amounts at 50+). Many teachers use both.
What happens to my 403(b) if I move out of state?
Your 403(b) is portable and yours regardless of where you live. You can roll it into an IRA when you separate from your district.
How does Illinois's 4.95% state tax affect my withdrawals?
Traditional 403(b) withdrawals are taxed as ordinary income in Illinois. Some states offer partial exemptions for retirement income — check current Illinois rules.
