People experiencing homelessness are eligible for the same health coverage programs as everyone else, and in most cases the path is more direct: Medicaid eligibility runs on income, not on having a lease or a mortgage. An unhoused individual with no income in a Medicaid expansion state usually qualifies immediately, without a permanent address or a photo ID, because federal rules require state Medicaid agencies to accept alternative documentation. Shelter residents, unsheltered individuals sleeping outside, and anyone transitioning between housing situations use the identical Medicaid application others fill out; the barriers are procedural, not eligibility-based.
Homeless adults face one real structural gap: the 10 states that have not expanded Medicaid to childless adults, where someone earning below 100% of the Federal Poverty Level can be too poor for a Marketplace subsidy and ineligible for Medicaid at once. The sections below cover Medicaid and presumptive eligibility, the Premium Tax Credit (PTC), the limited fit of a Health Savings Account (HSA), California's CalAIM housing benefits, catastrophic plan rules, and Marketplace Special Enrollment Period (SEP) triggers relevant to individuals without a permanent address.
Your 4 Real Options
Available options| Option | Best for | Typical cost |
|---|
| Medicaid (expansion states) | Income at or below 138% FPL in one of the 41 Medicaid expansion states plus D.C. | $0 to $50/month, most enrollees pay $0 |
| ACA Marketplace with full subsidies | Income between 100% and 150% FPL, especially in the 10 non-expansion states | $0 to $10/month for a Silver CSR plan |
| Hospital presumptive eligibility (temporary Medicaid) | Immediate care needed while a full Medicaid application is pending | $0 during the presumptive-eligibility period |
| HRSA Health Care for the Homeless Programs (FQHC) | Primary and behavioral health care regardless of insurance status | $0 to $50 per visit on a sliding-fee scale |
Homelessness is never a disqualifying factor for Medicaid, presumptive eligibility, or FQHC care. The subsidy cliff returned January 1, 2026; above 400% FPL, Marketplace plans are full price with no Premium Tax Credit.

Option 1: Medicaid in Expansion States
People experiencing homelessness qualify for Medicaid the same way anyone else does: household income measured against the Federal Poverty Level (FPL), not housing status. In the 41 states plus Washington, D.C. that have expanded Medicaid, adults at or below 138% of the 2026 FPL, $22,025 for a single adult, qualify regardless of a fixed address. Under 42 CFR 435.403, state Medicaid agencies must accept a shelter, friend, relative, or P.O. box as a mailing address. Unhoused individuals with $0 reported income are typically among the easiest applicants to approve.
Most Medicaid managed care plans cover primary care, mental health treatment, substance use disorder treatment, emergency care, and prescriptions at $0 copay for very-low-income enrollees. States must also allow a signed affidavit from a shelter staffer or case manager to attest to identity when standard documents are unavailable, so homeless adults who lack a photo ID or Social Security card can still apply. Coverage typically starts the first day of the application month, with 12 months of continuous eligibility in most states.
Option 2: ACA Marketplace Plans With Full Subsidies
Individuals without a permanent address living in one of the 10 states that have not expanded Medicaid, Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, and Wyoming, face a different calculation, since Marketplace premium tax credits only apply starting at 100% of the 2026 FPL ($15,960 for a single adult). Below that line, without a qualifying disability, pregnancy, or dependent child, single adults in non-expansion states fall into the Medicaid coverage gap: too little income for a subsidized plan, and no Medicaid pathway for childless adults.
Homeless population members who report income between 100% and 150% FPL in a non-expansion state, from part-time work, day labor, or disability benefits, can enroll in a Silver-tier Marketplace plan with cost-sharing reductions that often brings the premium and deductible to $0. The Premium Tax Credit (PTC) phases down as income rises and stops at 400% FPL, but the 100% to 150% band typically covers the entire premium. Applying through HealthCare.gov, using a shelter or outreach-program address, is the standard path.
Option 3: Hospital Presumptive Eligibility (Temporary Medicaid)
Hospital presumptive eligibility (HPE) lets a hospital or Medicaid-enrolled provider make a temporary eligibility determination on the spot, often the same day, based on a quick screening. Shelter residents and unsheltered individuals showing up in an emergency room without documentation can be enrolled under HPE and get bills covered through the presumptive period, usually the end of the following month, while a full application is submitted.
HPE exists to remove paperwork barriers for populations that struggle to produce income verification or identity documents on demand, exactly the barriers people experiencing homelessness face most. If the full Medicaid application that follows is denied, the temporary coverage already provided is not clawed back. Community Health Centers under HRSA's Health Care for the Homeless Program frequently run onsite HPE screenings during outreach visits.
Option 4: HRSA Health Care for the Homeless Programs (FQHCs)
HRSA's Health Care for the Homeless Program funds roughly 300 Federally Qualified Health Centers (FQHCs) and mobile outreach teams that treat patients regardless of insurance status or ability to pay. Every FQHC must operate a sliding-fee discount schedule based only on household income and size, per HRSA's Bureau of Primary Health Care rules. Patients at or below 100% FPL pay a nominal fee, often $0 to $50 per visit, whether or not they carry Medicaid or a Marketplace plan.
FQHCs also permit self-declared income when documentation is unavailable, a specific accommodation for shelter residents, unsheltered individuals, and anyone without pay stubs. FQHCs are not a substitute for Medicaid or Marketplace coverage for hospitalizations, but they are the most reliable first stop for primary care and behavioral health, and often help patients complete a Medicaid application onsite.
Traps That Cost Homelessness Thousands
People experiencing homelessness are underserved, not undeserving, but a few misconceptions and predatory products cause real harm:
Common traps for Homelessness| Trap | Why to avoid |
|---|
| Assuming $0 income disqualifies you from Medicaid | In the 41 Medicaid expansion states, $0 reported income places an applicant far below the 138% FPL threshold ($22,025 for a single adult in 2026) and is one of the most common reasons for approval, not denial. Skipping the application because there is no income to report leaves free coverage on the table. |
| The Medicaid coverage gap in non-expansion states | Ten states, Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, and Wyoming, have not expanded Medicaid to childless adults (Wisconsin covers adults up to 100% FPL through a state waiver, so it does not produce a full gap). Someone with $0 income in Houston or Atlanta can be ineligible for both Medicaid and Marketplace subsidies, which start at 100% FPL, a gap FQHCs and hospital presumptive eligibility exist to fill. |
| Losing coverage over undeliverable renewal mail | Medicaid redetermination notices sent to a shelter or outreach address that has changed, or a shelter stay that ended, are a leading cause of procedural disenrollment among unsheltered individuals. Update the address on file every time a shelter placement changes, and ask a case manager or FQHC to serve as an authorized representative for mail. |
| Discount cards and health share plans marketed as insurance | Medical discount cards and health share ministries are not insurance, do not have to pay claims, and typically exclude pre-existing conditions. They are sometimes marketed aggressively to uninsured, housing-insecure individuals, and homeless adults as a cheap alternative to Medicaid; a real Medicaid or Marketplace plan almost always costs less and covers more. |
Verify any plan is Medicaid, a Marketplace plan sold on healthcare.gov or a state exchange, or a HRSA-funded health center. If someone off the street or off social media pitches something else with a lower cost, ask why.

Medicaid eligibility for people experiencing homelessness in 2026
Medicaid eligibility for people experiencing homelessness runs on income compared against the Federal Poverty Level (FPL), not housing status. In the 41 states plus Washington, D.C. that have expanded Medicaid, an adult qualifies at or below 138% of the 2026 FPL. In the 10 states that have not expanded Medicaid, childless adults generally have no Medicaid pathway regardless of how low their income is, which is why the Marketplace and FQHCs matter so much for the homeless population there.
Federal Medicaid rules under 42 CFR 435.403 require state agencies to accept a shelter, case manager, friend, relative, or P.O. box address for mail, and a signed affidavit from a shelter or outreach worker when standard identity documents are unavailable. Coverage begins as soon as the application is approved, retroactive to the first day of the application month in most states, with 12 months of continuous eligibility regardless of income changes mid-year.
- A homeless shelter's address
- A case manager's, social worker's, or outreach worker's address
- A friend's or relative's address within the state
- A P.O. box
- General delivery at a local post office, permitted in some states
2026 Federal Poverty Level thresholds for Medicaid expansion and Marketplace subsidy eligibility| Household size | 100% FPL (2026) | 138% FPL Medicaid threshold (2026) | 400% FPL subsidy cliff (2026) |
|---|
| 1 | $15,960 | $22,025 | $63,840 |
| 2 | $21,640 | $29,863 | $86,560 |
| 3 | $27,320 | $37,702 | $109,280 |
| 4 | $33,000 | $45,540 | $132,000 |
| 5 | $38,680 | $53,378 | $154,720 |
| 6 | $44,360 | $61,237 | $177,440 |
| 7 | $50,040 | $69,055 | $200,160 |
| 8 | $55,720 | $76,894 | $222,880 |
| Each additional person | +$5,680 | +$7,838 | +$22,720 |
Figures apply to the 48 contiguous states and Washington, D.C.; Alaska and Hawaii use higher 2026 FPL figures. The 138% FPL column applies only in the 41 states plus D.C. that have expanded Medicaid; the 10 non-expansion states use 100% FPL as the floor for Marketplace subsidies instead.

Premium Tax Credit (PTC) eligibility for people experiencing homelessness in 2026
The Premium Tax Credit (PTC) matters most for people experiencing homelessness in one of the 10 non-expansion states, or whose income shifts during the year. Subsidies phase down as income climbs toward 400% of the 2026 Federal Poverty Level and stop at that line; at the low end, 100% to 150% FPL, the credit is large enough to bring a Silver-tier plan's premium and deductible close to $0 through cost-sharing reductions (CSRs).
Income projection is harder for people without a fixed address or steady pay stubs, since day labor, disability backpay, or a first paycheck after leaving homelessness can change PTC eligibility mid-year. Anyone who held a subsidized Marketplace plan for part of the year, then moved onto Medicaid or vice versa, receives Form 1095-A and must reconcile the advance PTC on their federal tax return; a free Volunteer Income Tax Assistance (VITA) site, many partnered with Health Care for the Homeless Programs, can complete this reconciliation.
HSA and HDHP fit for people experiencing homelessness in 2026
A Health Savings Account (HSA) pairs only with a High-Deductible Health Plan (HDHP), defined for 2026 as a minimum deductible of $1,700 self-only or $3,400 family, with a contribution limit of $4,400 self-only or $8,750 family, plus a $1,000 catch-up at age 55 or older. The HSA's triple tax advantage (deductible contributions, tax-free growth, tax-free qualified withdrawals) is real, but it depends on earned income to contribute and an HDHP to pair it with.
For most people experiencing homelessness, an HSA is not a practical tool. IRS Publication 969 disqualifies anyone enrolled in Medicaid from opening or contributing to an HSA, since Medicaid is not itself a qualifying HDHP. Flexible Spending Accounts (FSAs) are employer-payroll benefits, not available without formal W-2 employment, and should not be confused with HSAs. If someone later secures W-2 work with an HSA-qualified HDHP, the HSA becomes genuinely useful, but while Medicaid or a subsidized Marketplace Bronze plan is the coverage source, neither typically applies.
California's CalAIM Community Supports for Medi-Cal members experiencing homelessness
California's CalAIM initiative (2022 through 2026) added 14 optional Medi-Cal benefits called Community Supports, delivered through managed care plans rather than traditional billing. The 'housing trio,' housing transition navigation, housing deposits, and housing tenancy and sustaining services, exists specifically for Medi-Cal members experiencing homelessness and serves housing-insecure individuals across dozens of counties. More than 40% of members who used any Community Support used housing transition navigation, per the California Department of Health Care Services (DHCS).
Accessing Community Supports starts with a Medi-Cal managed care plan, not a separate application; a member asks their plan, a case manager, an FQHC, or a hospital discharge planner for a referral. Availability varies by county, since not every plan offers all 14 Community Supports. Outside California, comparable Medicaid housing-related benefits exist under Section 1115 demonstration waivers in states including Massachusetts, New York, and Arizona.
Marketplace Special Enrollment Period (SEP) triggers for people experiencing homelessness
A Marketplace Special Enrollment Period (SEP) opens a 60-day window to enroll in or change a plan outside the annual Open Enrollment Period, triggered by a qualifying life event. People experiencing homelessness encounter several of these triggers more often than the general population, since housing and income instability themselves generate qualifying events.
Losing Medicaid through a procedural termination, often an undeliverable redetermination notice after a shelter placement changed, triggers a 60-day SEP. Moving states, an income change crossing the Medicaid or 100% FPL threshold, release from incarceration, turning 26, and gaining a dependent round out the most common triggers for the homeless population. The state Medicaid expansion status guide explains what happens when a move crosses an expansion-state line.
- Loss of Medicaid coverage, including procedural termination: 60 days before or after
- Moving to a new state, county, or ZIP code with different plan options: 60 days after the move
- Income change crossing the Medicaid or 100% FPL threshold: 60 days after the change is reported
- Release from incarceration: 60 days after release
- Turning 26 and losing dependent coverage: 60 days around the birthday
- Gaining a dependent through birth, adoption, or foster placement: 60 days after the event
How to apply for Medicaid without a permanent address
Applying for Medicaid without a permanent address follows the same HealthCare.gov and state Medicaid portal process as everyone else, with federal rules built in to remove the address and documentation barriers people experiencing homelessness face most.
Documents that help but are not required: proof of income or a signed self-declaration of $0 income, a Social Security card or number, any photo identification, and immigration documentation for qualifying non-citizens. Common reasons applications get denied or delayed: leaving the mailing address blank instead of listing a shelter or case manager, a state incorrectly requiring a permanent residence (barred by federal law), missing the 90-day window to submit citizenship or immigration verification, and reporting income inaccurately instead of stating $0.
- Gather what is available: a Social Security number if known, any expired or current photo ID, and proof of income if any exists; none of these are required to start an application.
- Provide a mailing address that will actually be checked: a shelter, an outreach worker or case manager, a Federally Qualified Health Center, a friend or relative in the state, or a P.O. box.
- Apply online at HealthCare.gov or the state Medicaid agency's portal, by phone, in person at a Medicaid or Department of Social Services office, or through a Certified Application Counselor at a shelter or FQHC.
- Ask about hospital or FQHC presumptive eligibility for same-day temporary Medicaid if care is needed before the full application is processed.
- If identity or income cannot be verified with standard documents, request that a shelter staffer, case manager, or outreach worker sign a federally required affidavit attesting to the applicant's circumstances.
Frequently Asked Questions
What's the cheapest health insurance option for people experiencing homelessness in 2026?
Medicaid is almost always cheapest: in the 41 states plus Washington, D.C. that have expanded Medicaid, an adult at or below 138% of the 2026 Federal Poverty Level ($22,025 single) typically pays $0 in premiums. Zero reported income usually guarantees approval rather than disqualifying an applicant. In the 10 non-expansion states, a Marketplace Silver plan with cost-sharing reductions, available once income reaches 100% FPL ($15,960), is the next cheapest path. Federally Qualified Health Centers (FQHCs) offer $0 to $50 sliding-fee visits regardless of insurance status while an application is pending.
Do people experiencing homelessness qualify for the Premium Tax Credit?
Yes, if income falls between 100% and 400% of the 2026 Federal Poverty Level and Medicaid is not otherwise available. The Premium Tax Credit (PTC) phases down as income rises and stops entirely at 400% FPL ($63,840 for a single person in 2026); it does not apply below 100% FPL, which is where the Medicaid coverage gap in the 10 non-expansion states causes problems. Most people experiencing homelessness with very low or $0 income qualify for Medicaid instead of the PTC, since Medicaid is free and does not require a tax-return reconciliation. Anyone who used a subsidized Marketplace plan receives Form 1095-A and must reconcile the credit at tax time.
Can people experiencing homelessness deduct health insurance premiums on taxes?
For nearly everyone in this persona, no deduction applies. Form 7206, the self-employed health insurance deduction, only benefits people with net self-employment income, and most people experiencing homelessness have no such income, while Medicaid, the primary coverage source, has no premium to deduct in the first place. If someone earns occasional 1099 income and buys a Marketplace plan, Form 7206 could apply that year, but this is uncommon.
Can people experiencing homelessness use an HSA?
Rarely, and not while enrolled in Medicaid. A Health Savings Account (HSA) requires enrollment in a qualifying High-Deductible Health Plan (HDHP), and IRS rules disqualify anyone covered by Medicaid from contributing to an HSA at all, regardless of income. An HSA also requires earned income to contribute, which many people experiencing homelessness do not have. If someone later secures steady W-2 employment with an HSA-qualified HDHP (2026 contribution limits: $4,400 self-only, $8,750 family), the HSA becomes available at that point. Flexible Spending Accounts (FSAs) are employer-only and face the same practical barrier.
What happens if someone experiencing homelessness starts earning too much for subsidies?
Rising income above the subsidy cliff is uncommon for this persona but does happen as people find steady work and exit homelessness. The Premium Tax Credit phases down approaching 400% of the 2026 Federal Poverty Level and stops entirely at that line ($63,840 single, $132,000 for a family of four); above it, full sticker price applies. Update the Marketplace application within 30 days of any income change, since the advance credit is reconciled at tax time using Form 1095-A. Rising income can also mean losing Medicaid, which triggers a 60-day Special Enrollment Period.
When can people experiencing homelessness enroll in a Marketplace plan outside open enrollment?
A Marketplace Special Enrollment Period (SEP) opens a 60-day window after a qualifying life event. For this persona, the most common triggers are losing Medicaid through a procedural termination (often caused by undeliverable renewal mail after a shelter placement changed), moving to a new state or county, an income change crossing the Medicaid or 100% FPL threshold, release from incarceration, turning 26, and gaining a dependent. Anyone facing an unusual circumstance can also apply for a hardship exemption or a complex-case SEP through HealthCare.gov.
Does Medicaid require a permanent address for people experiencing homelessness?
No. Federal Medicaid rules (42 CFR 435.403) define state residency as where someone lives and intends to remain, explicitly including without a fixed address. Medicaid applications accept a homeless shelter's address, a case manager's or outreach worker's address, a friend's or relative's address, or a P.O. box for mail. Unhoused individuals without standard identification or income documentation can also submit a signed affidavit from a shelter worker or case manager attesting to their circumstances, which federal rules require states to accept.
Can people experiencing homelessness enroll in a catastrophic plan?
Technically yes, through the hardship exemption pathway, since Marketplace catastrophic plans are otherwise restricted to enrollees under 30. Homelessness itself typically qualifies for a hardship exemption. In practice, a catastrophic plan is rarely the best choice for this persona: catastrophic plans do not qualify for the Premium Tax Credit, so someone eligible for Medicaid or a subsidized Silver plan with cost-sharing reductions almost always gets better coverage at a lower cost than the catastrophic plan's 2026 deductible of $10,600.
