In a lot of states, earning a little too much for Medicaid just means you spend down the difference. Idaho doesn't work that way. Idaho is an income-cap state: for long-term-care Medicaid the gross monthly income limit is $2,982 in 2026, and a single dollar over it shuts the door unless you set up a Qualified Income Trust. That one rule changes how every over-income family in Idaho has to plan.
This guide walks through the 2026 income and asset limits for Idaho Medicaid for seniors and people with disabilities who need long-term care, why the income cap forces a Miller Trust instead of a spend-down, what a nursing-home resident keeps, and how the at-home spouse is protected.
The $2,982 income cap is the Idaho story
Idaho Medicaid is run by the Idaho Department of Health and Welfare (DHW). For nursing-facility care and home- and community-based waiver services, the state uses a single gross-income test called the special income standard, set at 300% of the SSI Federal Benefit Rate. For 2026 that works out to $2,982 a month (three times the $994 SSI benefit rate).
Here's 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 $2,982 is a hard cliff. One dollar over and you're ineligible, full stop, unless you do something about the excess.
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 workaround income-cap states use to let over-income applicants qualify. It's not a loophole and it's not optional in Idaho, it's the mechanism the program is built around.
Here's how it works. You set up an irrevocable trust, and each month the applicant's income that exceeds the $2,982 limit is deposited into it. Money inside the trust doesn't 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's an at-home spouse, then the cost of care), and whatever remains at death goes to the state up to the amount Medicaid paid.
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. Second, it has to be set up correctly and funded every single month; a trust that exists on paper but isn't funded doesn't 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 limit is $3,000.
"Countable" is the word doing the work. Idaho, like every state, exempts a long list of assets from the count: your 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.
The five-year look-back
Idaho reviews asset transfers made in the 60 months before a long-term-care application. Giving away money or property for less than fair market value during that window, signing a house over to a child for a dollar, gifting a grandchild a down payment, can trigger a penalty period during which Medicaid won't 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.
Long-term care: 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. Idaho sets its PNA at $40/month.
That $40 is on the lower end nationally, and it's 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 can't 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:
| Protection | 2026 Amount | What it does |
|---|---|---|
| Community Spouse Resource Allowance (CSRA) | Up to $162,660 (federal maximum); minimum $32,532 | The most in countable assets the at-home spouse may keep, on top of the applicant's own $2,000 limit. |
| Minimum Monthly Maintenance Needs Allowance (MMMNA) | Up to $4,066.50/month | The most monthly income the at-home spouse may keep; income can be shifted from the applicant to reach it. |
| Home-equity limit | $752,000 | Equity in the primary residence above this amount is countable for long-term-care eligibility. |
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 over $4,000 a month in income while the other spouse receives Medicaid-funded care. 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. Because any leftover Miller Trust funds also flow to the state at death, estate recovery and the QIT are linked in Idaho in a way families should understand up front. For how recovery works and where there's room to plan, see our Medicaid estate recovery explainer.
How to apply in Idaho
Idaho takes Medicaid applications through idalink, the state's online benefits portal at idalink.idaho.gov, or by phone at 1-877-456-1233. Long-term-care applicants also go through a level-of-care assessment to confirm they need nursing-facility-level services.
A practical note: if the applicant is over the income limit, set up and fund the Qualified Income Trust as part of the application process, not after. Because Idaho has no spend-down fallback, an over-income application without a funded trust is simply denied, and the timing of when the trust starts being funded matters for which months you can be covered. This is the single most common point where Idaho applications stall.
Frequently Asked Questions
For long-term care (nursing facility and HCBS waivers), the 2026 income limit is $2,982 a month in gross income, set at 300% of the SSI Federal Benefit Rate. Idaho is an income-cap state, so income above that figure makes you ineligible unless the excess is routed through a Qualified Income Trust.
Yes, if your income is over the limit. Idaho does not offer a medically needy spend-down for long-term care, so an over-income applicant must establish a Qualified Income Trust (also called a Miller Trust) and deposit the excess income into it each month to qualify. A trust that exists but isn't funded every month doesn't work.
$2,000 in countable assets for a single applicant, or $3,000 when both spouses are applying. The home (up to $752,000 in equity), one vehicle, household goods, and prepaid burial arrangements are exempt and don't count toward that limit.
For 2026, the community spouse can keep up to $162,660 in countable assets (the Community Spouse Resource Allowance, minimum $32,532) and up to $4,066.50/month in income (the Minimum Monthly Maintenance Needs Allowance). The home is generally protected up to $752,000 of equity.
A Personal Needs Allowance of $40/month. The rest of the resident's monthly income goes toward the cost of care, after any allowance shifted to a community spouse.
Apply online through idalink at idalink.idaho.gov or by phone at 1-877-456-1233. If you're over the income limit, set up and fund a Qualified Income Trust as part of the application rather than after, since there's no spend-down fallback and an unfunded over-income application is denied.
