Idaho Medicaid Eligibility Calculator (2026)
Idaho voters forced the expansion through a November 2018 ballot initiative; adults now qualify up to $1,836 a month. Idaho has the lowest children’s and pregnancy limits in the country, though — $4,326 and $3,142 for a family of three.

An expansion lawmakers keep reshaping
Coverage began January 1, 2020 after enrollment opened November 1, 2019.[KFF] In March 2025 the governor signed H0345, which directs the Department of Health and Welfare to seek work requirements and to let expansion adults between 100% and 138% of the poverty line take Marketplace tax credits instead of Medicaid; it also strengthened Idaho’s trigger law, requiring cuts to offset any drop in the federal match while the legislature is out of session.[KFF]
| Group | FPL | 1 | 2 | 3 | 4 | 6 |
|---|---|---|---|---|---|---|
| Adults 19–64 | 138% | $1,836 | $2,489 | $3,142 | $3,795 | $5,102 |
| Pregnancy | 138% | $1,836 | $2,489 | $3,142 | $3,795 | $5,102 |
| Children | 190% | $2,527 | $3,427 | $4,326 | $5,225 | $7,024 |
Children and pregnancy at the bottom of the range
Idaho’s separate CHIP stops at 185% of the poverty line (190% with the disregard), and pregnancy coverage at 133% (138%) — the lowest of any state on both counts.[MACPAC] A pregnant woman in a household of three earning $3,529 a month qualifies in most states but not in Idaho.
Postpartum, approved in 2025
Idaho was one of the later states to extend postpartum Medicaid to a year; CMS approved its state plan amendment on January 17, 2025.[KFF] Given Idaho’s 138% pregnancy limit, the extension mainly helps mothers who qualified at low incomes stay covered while their earnings recover.[MACPAC]
Applying
Apply through idalink. Idaho is an “SSI criteria” state, so SSI recipients file a separate Medicaid application; its poverty-level group for older adults sits at about 77% of the poverty line.[MACPAC]
Worked example
A Boise couple expecting a baby (a household of three for Medicaid) earns $3,500 a month. That is 153.7% of the poverty line for 3.
| Pregnant | over by $358 | $3,142 |
