A federal work requirement for Medicaid is no longer a proposal moving through Washington; it is a rule with a countdown attached, and the countdown does not start on the day the requirement itself takes effect. Anyone applying for coverage in Medicaid’s expansion group after January 1, 2027 will need to show a state proof of qualifying activity from months earlier, reaching back into the fall of 2026. The federal government’s own worked example lands that starting point in November 2026, though the exact month is a choice each state makes inside a range Congress set. For a household that expects to need Medicaid coverage at the start of next year, the paperwork period effectively opens before the calendar turns.
A 2025 tax law forces a 2027 Medicaid deadline
The requirement traces back to Section 71119 of the “Working Families Tax Cut” legislation, Public Law 119-21, which President Trump signed on July 4, 2025. That law added a new community-engagement condition to Medicaid eligibility for certain adults and directed the Centers for Medicare & Medicaid Services to write the rules for carrying it out. CMS did that on June 1, 2026, issuing an interim final rule known as CMS-2454-IFC.
The fact sheet CMS published alongside the rule states plainly that states must generally implement the requirement no later than January 1, 2027, though a state can move earlier through a Medicaid state plan amendment or a Section 1115 demonstration. Forty-three states and the District of Columbia currently cover the population the rule targets and will have to build the systems to run it.

Why the countable months can start in November, not January
The statute itself sets only a floor: an applicant must show at least one month of qualifying activity immediately before the month they apply. States, though, can require more. A CMS policy bulletin issued in December 2025 gives states the option of requiring one, two, or three consecutive months of demonstrated engagement before an application is approved, and it walks through exactly what that means on a calendar. For an application filed in January 2027, CMS’s own illustration works like this: a state requiring one month would look only at December 2026; a state requiring two months would look at November and December 2026; a state requiring three months would reach back to October, November, and December 2026.
That is where “the countable months begin in November” comes from — it is the middle of CMS’s own three options, not a single fixed number written into the statute. A state that keeps the shorter one-month floor would not need anything from a resident before December 2026. The number of months is a state-level decision, made as each Medicaid agency builds its verification system, and it is one of the first concrete choices a state has to publish before the requirement takes hold locally.
Who has to prove it, and who’s carved out
The requirement applies to what CMS calls “applicable individuals”: non-pregnant adults age 19 through 64 who are not enrolled in Medicare and who qualify for Medicaid through the Affordable Care Act’s expansion adult group, or through certain Section 1115 demonstrations offering equivalent coverage. To satisfy it for a given month, a person has to work, volunteer, or take part in a qualifying work program for 80 hours; enroll in school at least half-time; combine those activities to reach 80 hours; or already earn at least as much as 80 hours at the federal minimum wage, which comes to $580 a month in 2026. A long list of people are excluded from the requirement entirely rather than having to claim an exception: former foster youth, American Indians and Alaska Natives, parents and caregivers of a child 13 or younger or of a disabled family member, veterans with a total disability rating, people who are medically frail or have a serious medical condition, participants in addiction treatment, people who already meet SNAP or TANF work rules, and people who are pregnant or in the postpartum period. States can also choose to layer on short-term hardship exceptions for people in the hospital, in a federally declared disaster area, in a high-unemployment county, or traveling for specialized medical care.
A federal judge left the rule standing, but not all of it
Massachusetts and two dozen other states and the District of Columbia sued over the rule at the end of June 2026, in a case captioned Commonwealth of Massachusetts et al. v. Oz et al. in federal court in Boston. Their complaint does not challenge the January 2027 start date itself. It challenges three narrower pieces of the rule: folding a work-requirement element into the definition of who counts as “medically frail” and therefore exempt, a 12-month look-back period CMS uses when someone claims that exemption, and a version of the work requirement embedded in the short-term hardship exception for people in a federally declared disaster area.
On July 29, 2026, U.S. District Judge Richard G. Stearns denied the states’ request to block those three provisions while the case proceeds. He found the states had not shown harm that could not later be undone, partly because the federal government had committed to covering 90% of what states spend building the required eligibility systems, and partly because he attributed the tight schedule to Congress rather than to CMS, writing that “this timeline was set by Congress in H.R. 1, not by CMS in the challenged IFR.” The denial was without prejudice, meaning the states can ask again if the case’s merits briefing, due to wrap up before the rule’s implementation deadline, runs into trouble. As of this writing, the rule — including the January 1, 2027 date and the look-back period states are already choosing between — remains in effect nationwide.
What happens if the fall paperwork doesn’t clear
States are required to check payroll records, Medicaid provider data, and other information they already hold before asking an applicant or beneficiary for anything new. If a state still cannot confirm someone met the requirement, it has to send a notice of noncompliance and give the person 30 calendar days to demonstrate compliance or show that an exemption applies, and a beneficiary keeps coverage during that 30-day window. If nothing checks out by the end of it, the state has to look for any other basis for Medicaid eligibility before it can deny an application or end someone’s coverage, and anyone disenrolled can reapply at any time. The check does not happen only once: under a related provision of the same law, most of the same population moves to Medicaid renewals every six months instead of every twelve starting on that same January 1, 2027 date, so the fall look-back period that opens the door in fact recurs roughly twice a year for as long as someone stays enrolled.
