Medicaid Eligibility 2026 — Income Limits, MAGI Gap, Tips, Overtime & State Tax Decoupling

Tier A — Medicaid expansion, Modified Adjusted Gross Income (MAGI), and the tax decoupling gap

Under the Affordable Care Act (ACA), many states expanded Medicaid for adults with income up to 138% of the Federal Poverty Level (FPL), often using Modified Adjusted Gross Income (MAGI) rules. When federal tax policy allows extra deductions for tips or overtime, your federal MAGI can fall. If your state tax code decouples and does not allow the same subtractions, the state may still count your full gross wages — so your state MAGI stays higher. This calculator calls that mismatch a tax decoupling gap: you might owe less federal tax but still appear over the income limit for Medicaid on the state figure.

We flag a decoupling gap when federal MAGI is under the 138% FPL annual cap but state MAGI is above it. This is a teaching model; real Medicaid uses more categories than one screen can show.

Tier B — Optional Aged, Blind, and Disabled (ABD), institutional, and Home and Community-Based Services (HCBS) caps

Expansion adults are not the same as Aged, Blind, and Disabled (ABD) applicants or people seeking institutional (nursing home) Medicaid or Home and Community-Based Services (HCBS) waivers. Those programs often use monthly income standards, spousal rules, and asset tests that this tool does not fully model.

Tier B adds illustrative monthly thresholds for a few documented states so you can compare monthly state MAGI (annual state MAGI divided by 12) to a reference cap. Always confirm figures in your state Medicaid or human services manual.

Tier C — Supplemental Security Income (SSI), Section 1634, and Achieving a Better Life Experience (ABLE) accounts

In many states, approval for federal Supplemental Security Income (SSI) means you are automatically enrolled in Medicaid without a separate state income test — a pattern often discussed with Section 1634 of the Social Security Act. A minority of states require a separate Medicaid application even when you get SSI.

Achieving a Better Life Experience (ABLE) accounts let many people with disabilities save without losing benefits up to certain limits. We only warn when a balance you enter exceeds a modeled $102,000 caution point for Supplemental Security Income — we do not compute your actual SSI payment.

Tier D — Six-month renewals, monthly activity rules, and retroactive coverage (planning only)

Policy discussions have raised six-month (biannual) eligibility reviews for many expansion adults, with transitions often discussed around January 2027 and after — states implement on different timelines. Separately, some proposals target Able-Bodied Adults Without Dependents (ABAWDs) ages 19 through 64 for documenting roughly 80 hours per month of qualifying work, training, education, or community service, with broad exemptions (pregnancy, disability, caregiving, and more).

Retroactive Medicaid pays claims before the application date. Where retro periods shorten (for example from three months toward one month for some groups), waiting to apply can mean unpaid bills. This tier is for risk awareness, not a prediction of your letter date or work letter.

Formula notes (simplified educational model)

• Tips and overtime: We cap tips at $25,000 and overtime at $12,500 per year, then subtract them from gross income for federal Modified Adjusted Gross Income (MAGI). Above $150,000 (single or head of household) or $300,000 (married filing jointly), the combined deduction phases down by $100 for each $1,000 over that threshold.
• Married filing separately: This model applies no federal tip or overtime subtraction (aligned with the policy brief you supplied).
• State MAGI: If your state is coupled, state MAGI equals federal MAGI. If decoupled, state MAGI equals gross annual income with no tip or overtime subtraction here.

Non-expansion states (static dataset)

If your state did not adopt Medicaid expansion under the Affordable Care Act (ACA), the 138% Federal Poverty Level (FPL) adult expansion pathway in Tier A may not apply to you. You may still qualify under other rules, parents and children categories, or the Marketplace. Our list is a snapshot — verify with the Kaiser Family Foundation (KFF) or your state.

Authoritative sources to double-check

Centers for Medicare and Medicaid Services (CMS) publishes Medicaid and CHIP policy; KFF (Kaiser Family Foundation) tracks expansion and income rules; ASPE publishes the Federal Poverty Level; state Department of Health and Human Services (DHHS) or Medicaid portals publish eligibility manuals. State tax conformity for tips and overtime belongs to your state revenue or tax department.
