Idaho Medicaid Income Limits
Updated August 2026
Idaho expanded Medicaid through Proposition 2, which voters passed in November 2018. Expansion took effect January 1, 2020. The expansion category — adults ages 19–64 — added a significant new group to Idaho Medicaid eligibility. Before Proposition 2, Idaho was one of the last states without adult expansion. Figures below reflect the Idaho Department of Health and Welfare's official income limits, effective January 2026.

No asset test for MAGI-based Idaho Medicaid
Idaho Medicaid for adults under the expansion, children, and pregnant women uses MAGI-based rules with no asset test. Savings, vehicles, and home equity are not counted. This is standard for all ACA expansion states.
Idaho Medicaid for elderly and disabled individuals requiring long-term care uses separate income and asset rules. Per DHW's 2026 program income limits, Long-Term Facility Care and Home and Community Based Services (HCBS) both use a $3,002/month individual income limit with a $2,000 individual resource limit. The Aid to the Aged, Blind, and Disabled (AABD) program uses a $1,047/month individual income limit ($1,511/month for a couple), also with a $2,000 individual resource limit. The state enforces a 60-month look-back period for asset transfers before a long-term care application.
Idaho operates a Medicaid estate recovery program. The state may seek reimbursement from the estate of a member who received long-term care services at age 55 or older. Consult an Idaho-licensed elder law attorney before making asset transfers if a family member may need long-term care Medicaid.
Idaho does have a separate CHIP program for children above the Medicaid limit
Idaho covers children through Medicaid up to 138% FPL — the same MAGI standard used for expansion adults. Children whose family income falls between 138% and 190% FPL qualify for Idaho's Children's Health Insurance Plan (CHIP), a separate, state-administered program with its own monthly premiums (partially offset by the Children's Wellness Benefit for members current on checkups and immunizations). Children above 190% FPL who are not eligible for other programs may be able to access coverage through the federal health insurance marketplace at healthcare.gov.
