Illinois Retirement Mandate: What Employers Must Do

Illinois employers keep telling me the same story. They search for Illinois Secure Choice, land on a site called My Illinois Savings, and assume they have the wrong page. They do not. The program was renamed in June 2026 when it moved to a new recordkeeping platform. Same statute, same obligation, new sign over the door.

The rule underneath has not moved. If you operate in Illinois, cleared the headcount test in every quarter of the previous calendar year, have been in business at least two years, and sponsor no retirement plan of your own, the state gives you two compliant options. Facilitate its program, or sponsor a qualified plan. Doing neither carries a penalty assessed per employee.

What follows is who is covered, the deadline and why it returns every year, what noncompliance costs, how the auto-IRA works, and the decision that matters most: state program or your own 401(k). I build FirstHR for companies without a dedicated HR person. General information, not tax or legal advice.

The Rule Illinois Imposes

Illinois does not require you to offer a retirement plan. It requires you to offer retirement access, which is a narrower obligation, and the state supplies the vehicle if you decline to.

That distinction is the entire design. A covered employer either sponsors a qualified plan or connects its payroll to a state-run Roth IRA. Illinois was among the earliest of the states with mandatory retirement programs, so its enforcement machinery is more developed than most.

What Illinois Secure Choice Actually Is

Illinois Secure Choice is a state-facilitated automatic enrollment IRA overseen by the Illinois Secure Choice Savings Board, with administrative support from the Office of the Illinois State Treasurer. Since the platform migration it operates publicly as My Illinois Savings.

Employees of covered employers are enrolled into a Roth IRA funded by payroll deduction. The account is the employee's personal property rather than a company plan, so it travels with them when they leave. A private administrator handles recordkeeping under contract with the board, and the program charges participating employers nothing (Illinois State Treasurer). The rename matters for one practical reason: correspondence now arrives under an unfamiliar name, and unfamiliar mail gets filed as junk.

Which Illinois Employers Have to Register

You have to register if all three of these are true: you had at least five Illinois employees in every quarter of the previous calendar year, you have been in business two or more years, and you do not already offer or contribute to a qualified retirement plan. Fail any one and the mandate does not reach you this cycle.

The first test surprises people because it is measured quarter by quarter across the prior year rather than as an average. A business that ran lean for one quarter and staffed up for the other three does not meet it. One that held steady all four does, even at a size the owner thinks of as tiny.

The second test is useful for founders. A company hiring its first employees in Illinois has two years before this becomes a question, which is more room than several other state programs allow.

The Deadline, and Why It Returns Every Year

Illinois ran its original rollout in staged waves by employer size, all of which have closed. What replaced them is an annual cycle: the state identifies newly eligible employers from payroll filings, sends an access code, and attaches a November 1 deadline.

Two things follow. If your business was covered during an earlier wave and never registered, you are not waiting for a deadline, you are past one. And growth creates the obligation quietly: clear the headcount test for four consecutive quarters and the state sees it in the wage data you already file. That makes it a date for the compliance calendar.

What Missing It Costs

State law sets $250 per employee for the first calendar year of noncompliance and $500 per employee for each subsequent calendar year. Those years do not have to be consecutive to reach the higher tier.

Enforcement sits with the Illinois Department of Revenue rather than with the program. The program notifies the department of noncompliant employers, the department determines the total employee count from employer-reported data, then notifies the employer and demands payment, with an administrative hearing route for protests (Illinois Department of Revenue). Penalties became operable in February 2023. Because the department uses data you already submit, not registering does not make you invisible.

How the Auto-IRA Actually Works

Once you upload an employee, the program takes over. They receive program information and a thirty-day window to customize the account, change the savings rate, or opt out. Anyone who does nothing is automatically enrolled at the default rate.

The escalation detail is worth knowing before an employee asks. The default adds one percentage point each January once someone has been enrolled at least six months, continuing until the rate reaches ten percent. Employees can decline the increase in any year and set their own rate within federal limits.

The Roth default has a payroll consequence. Contributions come out after tax rather than reducing taxable wages, putting them on the opposite side of the pre-tax versus post-tax line from a traditional 401(k) deferral. Because the account is an IRA, the ceiling is the IRA limit rather than the far higher plan limit: per the IRS, $7,500 for 2026, with an additional $1,100 catch-up from age 50.

Where Your Responsibility Stops

You never contribute a dollar and you are never a plan fiduciary. That is not a footnote to the design, it is the reason the program exists in this shape.

By keeping employers out of contributions, investment selection, and plan sponsorship, the state keeps the arrangement outside the federal framework governing employer plans. The duties that come with sponsoring a plan yourself, fiduciary responsibility included, do not attach here. What remains is a payroll routine.

All of it slots into an existing process. If you already run payroll deductions, this is one more line item with a tighter remittance clock. You are not responsible for opening accounts, managing fund options, answering investment questions, or processing distributions.

Registering, or Certifying an Exemption

Both paths start the same way: your federal employer identification number and the access code the program sent to your business. Without the code you cannot do either, and the program will resend it to the email on file with the state revenue department.

Sponsoring Your Own 401(k) Instead

The second compliant path is to sponsor a qualified plan, which exempts you from the mandate and gives you a materially different product. The contribution ceiling is the headline difference.

The 2026 employee deferral limit for a 401(k) is $24,500 against $7,500 for an IRA, so an owner who wants to shelter meaningful income cannot do it through the state program. You can also match, which the state program prohibits outright, and a match is the feature most likely to move a candidate comparing two offers.

Cost is the usual objection and it is worth pricing rather than assuming. Per the IRS, an eligible small employer may claim a credit of up to $5,000 per year for three years toward setting up and administering a plan and educating employees about it, plus $500 per year for three years when the plan adds automatic enrollment. Several of those provisions were expanded by SECURE Act 2.0.

The trade is real. Sponsoring a plan brings plan documents, provider selection, annual filings, fiduciary duty, and depending on design, nondiscrimination testing, which is why a safe harbor structure is common at owner-led companies. The mechanics of a first plan are covered in our guide to a startup 401(k).

How to Choose Between Them

Both satisfy Illinois. They are not competing versions of the same product, and the choice usually resolves on the ceiling, the match, and your geography rather than on cost alone.

The last row decides it for distributed teams: one qualified plan resolves every state mandate at once, while the state route means separate registrations and deadlines layered onto the multi-state payroll work you already do. For a single-state employer with no matching budget, though, the state program is a reasonable answer rather than a consolation prize. One caveat on the plan route: part-time 401(k) eligibility follows its own federal rules.

Where Illinois Employers Get Caught

Four patterns, and the first costs the most. Assuming the mandate does not apply because the business feels small is the expensive one: the threshold is low, it is measured against every quarter of the prior year, and the state checks it against data you already file.

Having a plan and never certifying the exemption is second, and it produces the strange outcome of a fully compliant employer accumulating noncompliance notices.

Treating registration as the finish line is third. The roster upload, the seven-day remittance rule, and ongoing maintenance are the recurring obligations, and a registered employer can still drift out of compliance.

Assuming employees will all opt out anyway is last. Opt-out rates change nothing about the obligation, and the penalty is calculated on your employee count rather than on participation. Broader state obligations sit alongside this one on the Illinois compliance hub, worth one review pass for a business with no HR person.
