Idaho Medicaid Income Limits 2026: Eligibility & Asset Rules

Idaho Medicaid income limits depend entirely on which coverage you need. For most adults, the limit is 138% of the Federal Poverty Level, about $1,835 a month for one person in 2026. For long-term care, the gross monthly income cap is $3,002 for a single applicant, and a single dollar over it shuts the door unless you set up a Qualified Income Trust.1,2

This guide walks through the 2026 income and asset limits for Idaho Medicaid: the expansion-adult and aged, blind, and disabled pathways, then the long-term-care income-cap track in depth, including why that cap forces a Miller Trust instead of a spend-down, what a nursing-home resident keeps, and how the at-home spouse is protected.

Which Idaho Medicaid are you asking about?

Idaho Medicaid is run by the Idaho Department of Health and Welfare (DHW), and "the income limit" is not one number. It depends on the pathway you qualify under. There are three that matter to most families.

Expansion adults (the largest group). Idaho adopted the Affordable Care Act Medicaid expansion, enacted by voters as Proposition 2 in 2018. Adults age 19 to 64 with household income under 138% of the Federal Poverty Level qualify for full coverage, which is about $1,835 a month for a single-person household in 2026 (138% of the 2026 one-person poverty guideline of $15,960 a year). This pathway uses Modified Adjusted Gross Income (MAGI) rules and applies no asset test.1

Aged, blind, and disabled (ABD), not in long-term care. A senior or person with a disability who needs regular Medicaid but not nursing-facility care qualifies under the SSI-related Aid to the Aged, Blind, and Disabled (AABD) rules. For 2026 the AABD income limit is $1,047/month for an individual and $1,511/month for a couple, with a $2,000 individual ($3,000 couple) asset limit.2 A senior who is over that limit but still needs help with Medicare premiums and cost-sharing may instead qualify for the Medicare Savings Programs, which use higher income thresholds.

Long-term care (nursing facility and HCBS waivers). This is the track most people researching "Idaho Medicaid income limits" actually need, and it works differently from the other two. It carries a higher income ceiling ($3,002/month) but a hard cliff and a trust requirement that the rest of this guide covers in depth.2

The remainder of this guide focuses on that long-term-care track, because it is where the rules trip families up.

Idaho's long-term-care Medicaid income limit

For nursing-facility care and home- and community-based waiver services, Idaho uses a single gross-income test called the special income standard, set at three times the federal SSI benefit. For 2026 the Idaho Department of Health and Welfare publishes that limit as $3,002 a month for an individual and $5,984 for a couple.2

Here is what makes Idaho different from a state like Illinois or California. Idaho is an income-cap state. It does not run a medically needy spend-down for long-term care. In a spend-down state, income above the limit just becomes a monthly amount you have to incur in medical bills before coverage kicks in, so being over the line is an inconvenience, not a disqualification. In Idaho, gross income above $3,002 is a hard cliff. One dollar over and you are ineligible, full stop, unless you do something about the excess.2

That "something" is the Qualified Income Trust.

Over the limit? The Qualified Income Trust (Miller Trust)

A Qualified Income Trust (QIT), also called a Miller Trust, is the legal mechanism income-cap states use to let over-income applicants qualify. It is not a loophole and it is not optional in Idaho, it is the mechanism the program is built around.2

Here is how it works. You set up an irrevocable trust, and each month the applicant's income that exceeds the $3,002 limit is deposited into it. Money inside the trust does not count against the income test, so the applicant qualifies. The trust funds then get spent on the applicant's care under strict rules: the personal needs allowance, a spousal allowance if there is an at-home spouse, then the cost of care. Whatever remains at death goes to the state up to the amount Medicaid paid.2

Two things families get wrong about the Miller Trust. First, it only fixes an income problem, not an asset problem. The $2,000 asset limit still applies separately.2 Second, it has to be set up correctly and funded every single month; a trust that exists on paper but is not funded does not help. Because the rules are unforgiving, this is one of the clearer cases for an elder-law attorney. For the broader toolkit, see our guide to Medicaid planning strategies.

The asset limit: $2,000

Income is only half the test. To qualify for long-term-care Medicaid in Idaho, a single applicant may hold no more than $2,000 in countable assets; when both spouses are applying, the couple resource limit is $3,000.2

"Countable" is the word doing the work. Idaho, like every state, exempts a long list of assets from the count: the home (subject to an equity cap of $752,000 in 2026), one vehicle, household goods and personal effects, and prepaid burial arrangements. So the $2,000 ceiling applies to things like bank balances, investments, and a second car, not the roof over your head.2

The five-year look-back

Idaho reviews asset transfers made in the 60 months before a long-term-care application.2,4 Giving away money or property for less than fair market value during that window, signing a house over to a child for a dollar, or gifting a grandchild a down payment can trigger a penalty period during which Medicaid will not pay for long-term-care services, even though you otherwise qualify.

There are legitimate exceptions (transfers between spouses, transfers to a disabled child, certain caregiver-child home transfers) and legitimate planning approaches, but anything done inside the five-year window deserves an elder-law attorney's review first. If long-term care is on the horizon for someone in your family, talk to a professional before moving assets.

What a nursing-home resident keeps

When Idaho Medicaid pays for nursing-facility care, the resident contributes almost all of their monthly income toward the cost of that care. What they keep is the Personal Needs Allowance (PNA), a small sum reserved for personal expenses like clothing, a haircut, or a phone. Federal law sets a floor of at least $30/month for an aged, blind, or disabled resident, and states may set it higher; Idaho's institutional PNA is commonly reported at $40/month, though no primary Idaho .gov source publishes that exact figure.5,2

Either way, the allowance is on the low end nationally, and it is a number worth knowing before placement, because for a resident with no other resources it really is the entire monthly discretionary budget. For how the allowance is set and what it can and cannot be used for, see our explainer on the Medicaid personal needs allowance.

Protecting the spouse who stays home

When one spouse needs long-term care and the other stays in the community, federal spousal-impoverishment rules keep the at-home spouse from being left with nothing. Idaho applies the federal maximums for 2026:3

So a married couple sits in a very different position from a single applicant. The community spouse can hold up to $162,660 in countable assets and keep up to $4,066.50 a month in income while the other spouse receives Medicaid-funded care.3 When the applicant's income is shifted to the at-home spouse to reach the MMMNA, that shift happens through the Miller Trust's payout rules, another reason the trust has to be drafted with care.

After death: estate recovery

Like every state, Idaho runs a Medicaid estate-recovery program. After a recipient who was 55 or older and received long-term-care services dies, the state may seek repayment from the estate, unless the recipient is survived by a spouse or a minor, blind, or disabled child. Federal exceptions apply and an undue-hardship waiver exists.6,2 Because any leftover Miller Trust funds also flow to the state at death, estate recovery and the Qualified Income Trust are linked in Idaho in a way families should understand up front. For how recovery works and where there is room to plan, see our Medicaid estate recovery explainer.

How to apply for long-term-care Medicaid in Idaho

Idaho takes Medicaid applications through idalink, the state's online benefits portal. For a long-term-care case, the order of operations matters, because the trust has to be in place before the application can succeed.
