Retirement plans in Connecticut
Form 5500 filings for plan years 2009 to 2025; medians for plan year 2024.
Form 5500 information is as filed by the plan administrator with the Department of Labor and may be amended. Figures reflect the plan year shown, not current balances. A plan is counted in the state of its sponsor's address, not where its participants live.
For plan year 2024, 1,121 retirement plans based in Connecticut with 100 or more participants filed Form 5500: 992 defined contribution and 129 defined benefit. They reported 2,533,457 participant records and $320.3B in net assets, counting every plan on the form.
The median defined contribution plan held $71,392 per participant, well above the national median of $53,031, and its employer put in $2,529 per active participant (national: $2,174). Among plans reporting Schedule C compensation the median was $109 per participant against $123 nationally.
Employers contributed $5.75B and participants $8.23B during the year, and the plans paid out $27.9B in benefits.
In 2009 the same group numbered 1,439 plans with $194.6B; by 2024 it was 1,121 plans (down 22%) and $320.3B (up 65%). From plan year 2023 the 100-participant line counts participants with account balances, which moved many plans to the short form.
Beyond the full-form filers, 12,281 small plans based in Connecticut filed the short Form 5500-SF for 2024, with 288,707 participants and $23.1B in net assets. Small plans are counted here and nowhere else on this site.

Plan year is the year in which the plan year began. The drop in large plans from 2023 follows a rule change: the 100-participant line now counts participants with account balances, so many plans moved to the short form.

Questions and answers
How many retirement plans are there in Connecticut?
1,121 plans with 100 or more participants filed Form 5500 for plan year 2024, out of 1,846 pension plans on the full form. Smaller plans file Form 5500-SF and are counted separately where shown.
What is the typical 401(k) balance in Connecticut?
The median defined contribution plan reported $71,392 in net assets per participant (middle half of plans: $34,864 to $130,301); nationally it was $53,031. This is a plan-level average that includes former employees, not a typical person's balance.
What do employers contribute in Connecticut?
The median defined contribution plan received $2,529 in employer contributions per active participant, against $2,174 nationally. Plans with no employer contribution are included at zero.
What are average 401(k) fees in Connecticut?
Among defined contribution plans that report any Schedule C compensation, the median was $109 per participant and 0.18% of net assets (nationally $123 and 0.26%). Schedule C leaves out fund expense ratios and fees the employer pays, so it understates total cost.
Where does this come from?
Form 5500 annual reports in the EBSA research files, with filings received through 24 Aug 2026. Medians are computed by this site across plans with 100 or more participants.
