Michigan Restored IMLC Participation in March 2026: What Physicians Need to Know

For most of March 2026, Michigan was on track to exit the Interstate Medical Licensure Compact. PA 38 of 2022 — the law that brought Michigan into the compact in the first place — included a sunset provision that would have ended the state's participation on March 28, 2026. With days to spare, House Bill 5455 cleared the legislature on March 24, and Governor Gretchen Whitmer signed it into law as Public Act 6 of 2026 on March 26, 2026 — two days before the deadline. Michigan stayed in the compact without interruption. If you held a Michigan compact-issued license, used Michigan as your State of Principal Licensure (SPL), or had a pending IMLC file with Michigan in the chain, here is what changed and what to do next.

What Almost Happened

The 2022 enabling legislation contained a four-year sunset. Without affirmative legislative action, Michigan would have automatically withdrawn from the compact on March 28, 2026, with several practical consequences:

Michigan-issued Expedited Medical Compact licenses would no longer have been valid after the withdrawal date.
Physicians using Michigan as their State of Principal Licensure would have had to redesignate to another compact state to keep accessing the IMLC fast-track.
Pending IMLC applications routed through Michigan would have stalled, and any expedited licenses Michigan was preparing to issue would have been blocked.
Michigan would have reverted to single-state filings only, with the longer Michigan Department of Licensing and Regulatory Affairs (LARA) Bureau of Professional Licensing application as the sole path in.

The deadline created real anxiety. The Michigan State Medical Society and the Michigan Health & Hospital Association both pushed for a renewal vote. The Federation of State Medical Boards published a March 26, 2026 statement noting the legislative action. The Senate passed HB 5455 on March 24; Governor Whitmer signed two days later.

What PA 6 of 2026 Actually Does

PA 6 of 2026 amends the 2022 act to remove the sunset provision and continue Michigan's participation in the IMLC indefinitely, subject to standard compact rules and any future legislative changes. The structural pieces of Michigan's compact participation that were already in place stay in place:

Michigan continues as a compact member state, eligible to be selected as a State of Principal Licensure or as a state of expedited licensure.
The Michigan Bureau of Professional Licensing (BPL) inside LARA continues to administer the Michigan-side compact functions, including SPL verifications and the issuance of Michigan expedited licenses.
Existing Michigan compact-issued licenses remain valid. Renewals and redesignations continue through the normal IMLC channels.
The 25%-of-practice / residence / employer-location SPL eligibility test applies to Michigan as it does in every compact state.

If You Use Michigan as Your SPL

Nothing changes operationally. Your SPL designation is still valid. New LOQ requests will continue to flow through Michigan as before. If you redesignated to another compact state during the uncertainty (we saw a wave of physicians do exactly this in early March), you have two options:

Stay where you redesignated. If your residence, practice percentage, and employer make another compact state a clean SPL fit, there is no requirement to come back to Michigan.
Redesignate back to Michigan. If Michigan was your natural SPL fit and you only moved because of the sunset, you can redesignate back through the IMLC's standard redesignation process at imlcc.com.

If You Hold a Michigan Compact-Issued License

Your license is valid. The brief window in which it might have been invalidated has closed. Continue with normal renewal cycles through the IMLC. If you let it lapse during the uncertainty — for example, you decided not to renew because you expected the license to become invalid anyway — work with the IMLC and BPL on a reinstatement, since the underlying authority for the license is now restored.

If You Had a Pending IMLC File With Michigan

Files that were paused during the uncertainty are moving again. The most common pattern we are seeing:

Applications submitted before March 24 with Michigan as SPL or as a selected state are processing normally.
New applications opened after March 26 are unaffected.
A small subset of files that were administratively paused during the deadline window need a manual nudge through the IMLC support channel — these are usually files where the verification step happened to fall on March 25 or 26.

What Did Not Change

It is worth being concrete about what PA 6 of 2026 does not do:

It does not change Michigan's underlying medical practice act, which is administered by LARA. The Bureau of Professional Licensing still issues licenses, manages renewals, and handles disciplinary matters under Public Health Code Article 15.
It does not change Michigan CME requirements (currently 150 hours per three-year cycle, with subject-matter components for pain and symptom management, opioids, human trafficking identification, and implicit bias).
It does not affect single-state Michigan applications filed directly with LARA outside the compact — that pathway has always been available and continues to be.
It does not modify the IMLC bylaws or eligibility criteria. Eligibility is the same nationally as it was in February 2026.

Why This Matters Beyond Michigan

The Michigan story is a reminder that compact membership is a function of state legislation, and state legislation has sunsets, amendments, and political weather. The fix in Michigan was clean — a bipartisan sponsor, a unified medical-association push, and a governor signing two days before the deadline — but the next state to face a sunset may not have the same trajectory. If you are a multi-state physician relying on the IMLC, watch your SPL state's legislative calendar, and have a redesignation plan in your back pocket.

Practical Next Steps

If Michigan is in your licensure picture, here is the short list:

Confirm SPL status at imlcc.com. If you redesignated during the uncertainty, decide whether to come back or stay put based on your real practice profile, not the legislative news.
Verify that any Michigan compact-issued license is current. If a renewal fell during the uncertainty window, run the renewal through.
Check pending applications. Any IMLC file with Michigan in the chain that has not moved since March 22-26 may need a manual ping to the IMLC support team.
Review your CME calendar for the Michigan-specific subject components. The deadline drama did not change the CME requirements — but it is a good moment to look at them.

How White Glove Helped Through the Uncertainty

We spent the first three weeks of March 2026 fielding two calls a day from physicians asking whether to redesignate, whether to abandon Michigan files, and whether to convert pending compact applications to single-state LARA filings. The right answer in nearly every case was to wait, watch the legislative calendar, and move only if the bill stalled. Now that PA 6 is law, we are unwinding the precautionary redesignations for clients whose natural SPL was always Michigan, restarting paused files, and helping clients who did move to another SPL evaluate whether to stay there. Pricing for our concierge service is on our pricing page.

The short version: Michigan is in the IMLC. Your file is fine. If you made a precautionary move during the uncertainty, decide on its merits — not on a deadline that no longer applies.
