Medicaid income limits define the amount of income a person or family can have to qualify for Medicaid in a given eligibility group and state. These limits are generally set as a percentage of the federal poverty level (FPL) and can vary by age, household size, disability status, and whether coverage is sought through expansion or traditional Medicaid. Income rules also differ for groups such as children, pregnant people, parents, and adults without dependents, with many states using Modified Adjusted Gross Income (MAGI) as the main eligibility measure. Below is a detailed, evergreen explanation of how Medicaid income limits work and how to interpret them in practice.
How Medicaid Income Limits Work
Medicaid is a joint federal and state program, and while federal guidelines establish a framework, each state determines specific eligibility criteria within those parameters. As a result, income limits are not uniform nationwide but are adjusted at the state level and updated annually. The primary goal of these limits is to ensure that coverage is targeted toward individuals and families with limited financial resources. For many groups, especially children and parents in expansion states, limits are set close to or above the federal poverty level, while non-expansion states often set limits well below it.
Modified Adjusted Gross Income (MAGI) and Medicaid
Modified Adjusted Gross Income (MAGI) is the method most states use to determine Medicaid eligibility for certain populations. MAGI generally includes wages, self-employment income, Social Security benefits, unemployment compensation, and other forms of taxable income, while excluding certain adjustments and non-taxable income sources. Because MAGI is based on federal tax information, it can make the application process more consistent and predictable. States may still apply additional rules, such as disregarding some income sources or allowing deductions, so applicants should verify specifics with their state agency.
Federal Poverty Level (FPL) as a Baseline
The federal poverty level serves as the baseline for many Medicaid income limits. In most expansion states, Medicaid coverage for adults is available up to 138% of the FPL, though some states set limits slightly below or above that threshold. For children, income limits are often set several times higher than the FPL, particularly for younger children. Pregnant individuals may qualify at higher income levels through separate programs or Medicaid expansions. Parents in non-expansion states may face much lower limits, sometimes in the low single digits of the FPL, which can result in coverage gaps.
Countable Income vs Excluded Income
Not all income is counted when determining Medicaid eligibility. Programs and benefits typically excluded from countable income include Supplemental Security Income (SSI), many temporary assistance programs, and certain low-income housing benefits. Some states also exclude small savings accounts, disability-related work expenses, or child support received. However, programs such as cash assistance, unemployment insurance, and self-employment income are generally counted. Understanding which income sources are included can help applicants more accurately assess their eligibility.
State Variation and Annual Updates
Because states have flexibility in setting eligibility criteria, the same applicant may qualify in one state but not another. For example, an adult without dependents might qualify for Medicaid in an expansion state with an income limit at or near 138% FPL but find no coverage option in a non-expansion state. States also update their income limits annually to reflect changes in the FPL and economic conditions, meaning eligibility can change from one year to the next. These shifts can cause people to gain or lose coverage if their income remains stable but limits move.
Household Size and Composition
Household size plays a critical role in determining income limits. Larger households are allowed higher income thresholds because total living costs increase with more residents. Medicaid rules typically define household members broadly, including tax dependents and others who live and share expenses. When applicants report income, they must include the gross income of all household members unless specific exclusions apply. This means that a higher earner in the household can affect eligibility for others, even if they are not applying for Medicaid themselves.
Practical Steps to Check Eligibility
Because income limits and rules differ so widely, the most reliable way to check eligibility is to contact your state Medicaid agency or use its online screening tool. Applicants can prepare by gathering recent pay stubs, tax returns, Social Security statements, and information about any public assistance programs. Many states allow online applications, and some offer options to renew coverage or report changes in circumstances throughout the year. Reapplying or reporting changes promptly can help prevent interruptions in coverage and ensure continued eligibility.
Special Circumstances and Programs
Certain groups, such as individuals with disabilities, may qualify for Medicaid through pathways unrelated to income limits, including programs like the Institutional Care Program or Katie Beckett waivers. States also have options to extend postpartum coverage and implement continuous eligibility policies during public health emergencies. While these programs and policies do not change baseline income limits, they can provide coverage to people who might otherwise fall outside standard eligibility criteria.

| Attribute | Verified Detail | Source Type |
|---|---|---|
| Eligibility Basis | Most states use MAGI, a tax-based income measure | Federal guidance and state practices |
| Adults in Expansion States | Often eligible up to 138% of the Federal Poverty Level | State Medicaid plans |
| Children | Income limits frequently set several times the FPL | State children’s Medicaid policies |
| Non-Expansion States | adultsLimits for parents may be far below the FPL, sometimes single digits | State policy analyses and CMS data |
| Household Definition | Broad, often includes dependents and shared household members | Medicaid household rules |
Common Income Types Counted and Not Counted
When determining Medicaid eligibility, not all income is treated the same. Knowing which sources count and which are excluded can help applicants understand their situation more clearly. Below is a comparison of common income types.
Countable Income
- Wages and salaries from employment
- Self-employment net earnings
- Unemployment insurance and workers’ compensation
- Social Security retirement and disability benefits (usually counted)
- Pensions and annuities
Typically Excluded or Not Counted Income
- Supplemental Security Income (SSI)
- Low-income housing benefits and certain rental assistance
- Childcare assistance and foster care payments
- Some disability-related work expenses or impairment-related work expenses
- Small life insurance policies and savings in some states
State Plan Amendments and Policy Changes
States can adjust Medicaid eligibility through State Plan Amendments, which may change income limits, household rules, or the populations served. These amendments are reviewed by the Centers for Medicare & Medicaid Services (CMS) and can be tied to federal options or requirements. Policy changes can expand coverage in some years or tighten rules in others, so it is important to rely on current state-specific guidance when assessing eligibility.
Bottom Line
Medicaid income limits are set by each state within federal parameters and determine who can enroll in the program. Modified Adjusted Gross Income (MAGI) is the standard method used in many states, though rules for counting income vary. Limits differ by household size, age, and whether the state has expanded Medicaid under the Affordable Care Act. Because policies update regularly and differ by location, applicants should check their state’s current rules using official resources to understand their specific eligibility.
