Key Takeaways
- Medicaid eligibility is based on current monthly income, so a raise or new job can disqualify you quickly.
- You must report income changes to your state Medicaid agency, usually within 10 to 30 days.
- Losing Medicaid counts as a qualifying life event, triggering a Special Enrollment Period on the ACA marketplace.
- Premium tax credits on the marketplace are available to most people earning between 100% and 400% of the federal poverty level.
- Some states offer a Medicaid spend-down program if your income is only slightly over the limit.
- Coverage gaps during the transition are avoidable if you act promptly and understand your timeline.
Why Income Changes Matter for Medicaid
Medicaid is an income-based program, which means your eligibility is directly tied to how much money you earn. Unlike employer-sponsored insurance or Medicare, there is no set enrollment window each year — your eligibility can change any month your financial situation shifts. A new job, a pay raise, a promotion, or even a change in household size can push your income above the threshold your state uses to determine who qualifies.
Under the ACA, most states expanded Medicaid to cover adults earning up to 138% of the federal poverty level (FPL). As of 2024, that translates to roughly $20,120 per year for a single adult. But these thresholds differ by state and by household size, and not all states have expanded Medicaid. Understanding exactly where your income falls relative to your state's threshold is the first step in managing this transition wisely.
This article walks you through what actually happens when your income goes up — what you're required to report, how your coverage changes, and what to do next so you don't end up uninsured between programs. See also our guide on where the Medicaid and marketplace income boundary falls for a side-by-side comparison.
What you will need
Understanding the Income Thresholds
Medicaid eligibility thresholds are expressed as a percentage of the federal poverty level (FPL), which the federal government updates each year. Your state then sets its own cutoff — typically 133% or 138% of FPL in expansion states — and applies it to your modified adjusted gross income (MAGI), which is the income standard used for most ACA-related programs.
Key income thresholds to know
| Household Size | 138% FPL (2024) | 100% FPL (2024) | 400% FPL (2024) |
|---|---|---|---|
| 1 person | ~$20,120 | ~$14,580 | ~$58,320 |
| 2 people | ~$27,214 | ~$19,720 | ~$78,880 |
| 4 people | ~$41,400 | ~$30,000 | ~$120,000 |
Why does the 400% FPL number matter? Because that used to be the upper ceiling for premium tax credits on the ACA marketplace. Through the end of 2025, the American Rescue Plan and Inflation Reduction Act extended enhanced subsidies beyond that cap — but this could change again depending on future legislation. Always verify current subsidy rules when you're making enrollment decisions.
In non-expansion states (currently about 10 states, mostly in the South), the Medicaid income limit for adults without dependent children can be extremely low — sometimes below 50% FPL. If you live in one of these states and your income increases past a modest threshold, you may find yourself in a coverage gap where you earn too much for Medicaid but too little for marketplace subsidies. This is a known policy issue, and it disproportionately affects low-income adults in those states.
If your income is only slightly above the Medicaid cutoff in your state, you may still have options. Some states allow a process called Medicaid spend-down, which lets you qualify even with higher income by subtracting medical expenses.

Step-by-Step: How to Transition from Medicaid to Marketplace Coverage
The transition from Medicaid to a marketplace plan has several moving parts, but it follows a predictable sequence. Follow these steps to avoid a gap in coverage and ensure you're enrolled in the right plan at the right time.
Calculate your new projected annual income
Start by determining your new gross monthly income from all sources — wages, self-employment, alimony, investment income, and any other income counted under MAGI rules. Multiply your monthly gross income by 12 to get your projected annual income. Then compare this number to your state's Medicaid income limit for your household size.
Use the federal poverty level tables (updated each January) to express your income as a percentage of FPL. If your projected income exceeds your state's Medicaid threshold — typically 138% FPL in expansion states — you are likely no longer eligible for Medicaid.
Report the income change to your state Medicaid agency
You are legally required to report significant income changes to your state Medicaid agency. The reporting window varies by state, but it is typically 10 to 30 days from the date the change occurs. You can usually report the change through one or more of the following channels:
- Your state's Medicaid online portal or beneficiary account
- Calling your state's Medicaid helpline directly
- Visiting your local Medicaid or social services office in person
- Mailing or faxing a change report form (check your state agency's website for the correct form)
When you report the change, your state will reassess your eligibility. If your income now exceeds the limit, they will send you a notice of termination, which will include your coverage end date.
Confirm your Medicaid termination date
Once your state processes the income change, they will send a formal notice stating the exact date your Medicaid coverage will end. This date is critical because it starts your 60-day Special Enrollment Period (SEP) clock for marketplace enrollment. Save this notice — you may need to upload it as documentation when applying for a marketplace plan.
In most states, coverage ends at the end of the month in which your eligibility was determined to have lapsed. So if the state processes your change in mid-October, your Medicaid typically runs through October 31.
Apply for marketplace coverage using your Special Enrollment Period
Losing Medicaid due to an income increase is a qualifying life event, which means you can enroll in a marketplace plan outside of the standard Open Enrollment Period. You have 60 days from your Medicaid end date to select and enroll in a marketplace plan.
To apply, go to HealthCare.gov (or your state's own marketplace if you live in a state that runs its own exchange). When asked for a reason for your Special Enrollment Period, select "Loss of qualifying health coverage" or the equivalent option. You'll be asked to enter your estimated annual income for the current year, which determines your eligibility for premium tax credits and cost-sharing reductions.
Compare plans and select the right metal tier
Marketplace plans come in four metal tiers — Bronze, Silver, Gold, and Platinum — each with different premium and cost-sharing structures. Here's a quick guide:
- Bronze: Lowest premiums, highest deductibles. Best if you're generally healthy and want catastrophic protection.
- Silver: Mid-range premiums. Critically, this is the only tier that qualifies for cost-sharing reductions if your income is below 250% FPL.
- Gold: Higher premiums, lower deductibles. Better if you use healthcare frequently.
- Platinum: Highest premiums, lowest out-of-pocket costs. Rarely cost-effective for most consumers.
For most people coming off Medicaid — who are accustomed to low or no cost-sharing — a Silver plan with cost-sharing reductions is often the best fit if income qualifies. Compare the Summary of Benefits and Coverage (SBC) for each plan you're considering, and pay attention to whether your current doctors and prescriptions are covered.
Confirm your enrollment and set up premium payments
After selecting a plan, complete your enrollment by paying your first month's premium before your coverage start date. Most insurers require the first payment within 30 days of enrollment, but check your plan's specific deadline — failure to pay on time will void your enrollment. Set up autopay if possible to avoid accidental lapses in future months.
You should receive a member ID card from your new insurer within 1–2 weeks of enrolling. Keep this handy, and notify your doctors and pharmacy of your new insurance as soon as possible.
What to Expect After You Enroll in a Marketplace Plan
Once you've selected a marketplace plan, your new coverage will typically begin on the first day of the month following your plan selection, as long as you enroll before the 15th of that month. If you enroll between the 16th and the last day of the month, coverage usually starts the first of the second following month. This timing is critical — you want to coordinate it so that your Medicaid ends and your marketplace plan begins without a gap.
What changes when you move to a marketplace plan
- Premiums: Unlike Medicaid, which is free or very low-cost for most enrollees, marketplace plans charge monthly premiums. However, premium tax credits can significantly reduce this cost. See the Premiums and Deductibles hub for a full explanation of how these costs work.
- Deductibles and cost-sharing: Marketplace plans have deductibles, copays, and out-of-pocket maximums that Medicaid typically does not. If you qualify for a Silver plan with cost-sharing reductions (CSR), your out-of-pocket costs will be lower.
- Provider networks: Your current doctors may or may not be in your new plan's network. Always verify network status before finalizing a plan.
- Drug formularies: Prescription drug coverage varies between plans. Check that your medications are covered before you enroll.
Cost-Sharing Reductions: A Hidden Marketplace Benefit
If your income is between 100% and 250% of the federal poverty level and you enroll in a Silver-tier marketplace plan, you automatically qualify for cost-sharing reductions (CSRs). These reductions lower your deductibles, copays, and out-of-pocket maximums — sometimes dramatically. A Silver plan with CSRs can provide coverage that feels closer to Medicaid in terms of what you actually pay at the doctor's office.

Check CHIP Eligibility for Your Children Separately
Even if your income increase makes you ineligible for Medicaid as an adult, your children may still qualify for Medicaid or CHIP at a higher income threshold. In most states, children are eligible up to at least 200% FPL, and in many states up to 300% or higher. Always check your children's eligibility independently whenever your household income changes.

Special Situations: Pregnancy, Part-Year Income, and Household Changes
Not every income increase follows a clean, predictable path. Several common life situations can complicate the transition from Medicaid.
Pregnant enrollees
Pregnant women often qualify for Medicaid at higher income thresholds — in some states, up to 200% or 215% FPL during pregnancy. If you're pregnant and your income increases, your eligibility rules are different from those that apply to non-pregnant adults. Many states will keep a pregnant enrollee on Medicaid for the duration of the pregnancy and for a defined postpartum period (now extended to 12 months in most states under federal option). See our detailed guide on Medicaid for pregnant women, income limits, and coverage for more detail.
Variable or part-year income
Freelancers, seasonal workers, and gig economy workers often experience income that fluctuates month to month. Medicaid eligibility is generally assessed on current monthly income projected annually, not on last year's tax return. This means a good month can push you out of Medicaid, but a slow month can bring you back in. In practice, states vary widely on how they handle fluctuating income — some will average it, others assess it monthly. Contact your state Medicaid office to clarify how they handle variable income in your specific case.
Variable Income and Medicaid Churning
If your income fluctuates — as it often does for gig workers, freelancers, or seasonal employees — you may find yourself cycling in and out of Medicaid eligibility repeatedly. This is sometimes called Medicaid churning, and it creates administrative burden and coverage gaps. If your income varies widely, ask your state Medicaid office how they assess variable income, and consider whether a marketplace plan with predictable costs might offer more stability.
Avoid Overlapping Coverage Issues
Do not enroll in a marketplace plan while your Medicaid coverage is still technically active. Overlapping coverage between Medicaid and a marketplace plan can cause billing complications and may affect your subsidy eligibility. Wait until you have a confirmed Medicaid end date before selecting your marketplace plan start date.
Household size changes
If your household composition changes — a spouse moves in, a child leaves your household, or you gain or lose a dependent — your Medicaid eligibility may shift even without an income change. This is because both income thresholds and MAGI calculations are based on household size. Report these changes to your state agency promptly, just as you would an income change.
You Have 60 Days — Don't Miss It
Your Special Enrollment Period for marketplace coverage lasts only 60 days from the date your Medicaid coverage ends. If you miss this window, you will need to wait until the next Open Enrollment Period — typically November 1 through January 15 — to enroll. This could leave you uninsured for several months. Mark your Medicaid termination date on your calendar and begin comparing marketplace plans as early as possible.
Household Composition Affects Eligibility Too
Medicaid eligibility is calculated based on both income and household size. A change in who lives in your home — a new partner, a child turning 19 and aging off, or a dependent moving out — can affect your eligibility even without a change in income. Report both income changes and household composition changes to your state Medicaid agency promptly, as failing to do so can result in coverage you're not entitled to, which the state may seek to recover.
Retroactive Medicaid
One benefit many people don't know about: if you recently had medical bills before your Medicaid application was processed, you may be eligible for retroactive coverage going back up to three months. This can help cover costs you incurred while you were transitioning between coverage. Read our article on retroactive Medicaid and how coverage before your application date works.
Common Mistakes to Avoid During the Transition
Even well-informed consumers make avoidable mistakes during the Medicaid-to-marketplace transition. Here are the most common ones and how to sidestep them.
Waiting too long to report income changes
Most states require you to report income changes within 10 to 30 days. Waiting until your annual renewal can result in overpayments, which the state may try to recover. It can also leave you ineligible but still enrolled — creating legal exposure.
Missing the Special Enrollment Period window
You have 60 days from the date you lose Medicaid to enroll in a marketplace plan under a Special Enrollment Period. Missing this window means waiting until Open Enrollment (typically November 1 through January 15 in most states), which could leave you uninsured for months.
Assuming your income estimate is final
When you apply for marketplace subsidies, you estimate your annual income for the coming year. If your actual income turns out higher than estimated, you may owe some or all of the premium tax credits back at tax time. If it turns out lower, you may get additional credits. Update your income estimate on the marketplace whenever your situation changes to avoid large tax-time surprises.
Not checking for CHIP eligibility for children
Even if you lose Medicaid eligibility as an adult, your children may still qualify for Medicaid or the CHIP program at a higher income threshold. Don't assume that because you no longer qualify, your children don't either. Check their eligibility separately.
The transition from Medicaid to marketplace coverage is manageable when you understand the rules and act within the required timeframes. The key is to report changes promptly, know your Special Enrollment Period window, and compare marketplace plans carefully before selecting one. State rules vary, so when in doubt, call your state Medicaid office or use the HealthCare.gov chat tool for guidance specific to your situation.
