As healthcare costs continue to rise, understanding Medicaid eligibility is critical for millions of low-income single adults across the United States. The year 2025 brings updated income thresholds, which vary significantly by state due to the Affordable Care Act (ACA) Medicaid expansion. This article provides a professional overview of the federal baseline, state-by-state variations, and key considerations for single adult applicants.

Federal Baseline: The 138% FPL Rule

Under the ACA, states that expanded Medicaid must cover adults under age 65 with incomes up to 138% of the Federal Poverty Level (FPL). For a single adult in 2025, the FPL is projected to be approximately ,060 for the 48 contiguous states and D.C. Therefore, the standard income limit in expansion states is roughly ,783 per year (or about ,732 per month).

It is important to note that 138% FPL includes a standard 5% income disregard, meaning the effective threshold is 133% FPL for calculation purposes, but the final eligibility is based on 138%.

State-by-State Variations: Expansion vs. Non-Expansion

As of 2025, 40 states and Washington D.C. have adopted Medicaid expansion. In these states, single adults under 65 qualify with incomes at or below 138% FPL, regardless of whether they have children or a disability.

However, 10 states have not expanded Medicaid. In these states, eligibility for single adults is extremely limited. Generally, non-expansion states only cover parents (with dependent children) and individuals who are elderly, blind, or disabled. Childless, non-disabled adults often remain ineligible, regardless of how low their income is.

Non-Expansion States (2025)

• Alabama
• Florida
• Georgia
• Kansas
• Mississippi
• South Carolina
• Tennessee
• Texas
• Wisconsin (limited coverage)
• Wyoming

Important: In non-expansion states, even if a single adult has an income of ,000 per year, they may not qualify for traditional Medicaid unless they meet specific categorical requirements (e.g., disability).

Income Counting Rules

Medicaid uses Modified Adjusted Gross Income (MAGI) to determine eligibility for most adults. MAGI includes wages, salaries, tips, net self-employment income, unemployment compensation, Social Security benefits (excluding SSI), and certain other income. It does not include child support, veteran’s disability benefits, or Supplemental Security Income (SSI).

For single adults, the calculation is straightforward: the monthly gross income (before taxes) is compared to the state’s income limit. Some states apply a small disregard for earned income, but the 138% FPL limit is the primary benchmark.

Asset and Resource Tests

For most single adults under 65 applying through the ACA expansion, there is no asset test. This is a significant change from traditional Medicaid. Savings accounts, retirement funds, vehicles, and homes are generally not counted. However, non-expansion states and coverage for the elderly/disabled (e.g., nursing home Medicaid) still impose strict asset limits, typically ,000 for a single adult.

Special Considerations for 2025

1. Redetermination and Unwinding: States are continuing to redetermine eligibility after the COVID-19 Public Health Emergency unwinding. Single adults who were previously enrolled may lose coverage if their income has changed or if they fail to return renewal forms.
2. State Waivers: Some states have Section 1115 waivers that impose work requirements or premium payments. For example, Georgia’s partial expansion (Pathways to Coverage) has different limits. Always check state-specific rules.
3. Income Fluctuations: Medicaid eligibility is generally based on current monthly income. If you lose a job or have a seasonal income drop, you may qualify even if your annual income is above the limit.

How to Apply

Single adults can apply for Medicaid through the Health Insurance Marketplace (HealthCare.gov) or directly through their state Medicaid agency. Applications are free, and eligibility is usually determined within 45 days. If you are in a non-expansion state, you may be directed to a state-specific program or to the Marketplace for subsidized private insurance.

Conclusion

For single adults in 2025, Medicaid eligibility hinges primarily on state expansion status. In expansion states, the income limit is approximately ,783 per year with no asset test. In non-expansion states, most childless adults remain ineligible. As healthcare policy continues to evolve, it is essential to verify your state’s current rules and apply promptly if your income qualifies. Professional assistance from a certified enrollment counselor or Medicaid planner can help navigate complex situations.
