USDA income limits in Idaho for 2026
The 2026 USDA income limit in Idaho is $122,800 for a household of one to four people and $162,100 for five to eight, effective July 13, 2026 under USDA Procedure Notice 657. Here is something worth stating plainly, because a lot of pages get it wrong: Idaho uses that national floor in every county, with no high-cost exceptions. Even Ada County around Boise and the resort counties of Blaine and Teton run at the standard limit, not a higher one.
The limit counts your whole household's income, and it is your adjusted income after USDA's deductions, not your gross pay. From USDA Handbook HB-1-3555:
"Income from all adult household members, not just parties to the note, must be considered."
Idaho's median household income is about $81,166 (Census, 2024), roughly $41,000 under the cap, so the large majority of Idaho households qualify on income. Confirm your county on the USDA income eligibility tool.
How much of Idaho is USDA-eligible? Almost all of it
Idaho is one of the strongest USDA states in the country. Nearly the entire state is eligible by geography. The only ineligible zones are the incorporated urban cores: the Treasure Valley cities of Boise, Meridian, Nampa, and Caldwell, plus the cores of Coeur d'Alene, Idaho Falls, and Pocatello. Everything outside those footprints, the ring towns, the small cities, and the rural counties, is eligible. Combine that near-universal eligibility with incomes under the cap, and most of Idaho can actually use USDA, which is not true in most states.
Eligible towns in the Treasure Valley ring
The farm towns around the Boise metro are the sweet spot, with verified median household income and median home value (Census, 2024):
- Middleton (10,649, income $89,013, value $403,100)
- Emmett (8,275, $58,750, $342,000)
- Weiser (5,935, $45,292, $223,400), the most affordable of the group
- Homedale (3,069, $62,117, $238,000), Parma (1,928, $49,231, $274,300), Marsing (1,306), and New Plymouth (1,794)
Two to watch: Star and Kuna have grown fast, to about 14,745 and 27,158 people with median home values of $564,300 and $423,900. Their growth is pushing them toward ineligibility on both the map and, for some buyers, income. Verify any address in those two before you count on it.
Affordability: eligible and within reach
Idaho's median home value is about $446,400 (Census, 2024), but the eligible ring towns run well below that: Weiser at $223,400, Homedale at $238,000, Parma at $274,300. Those are comfortably covered by USDA's 100% financing, and the state's incomes sit under the cap, so the two constraints that stop USDA buyers elsewhere, income and geography, rarely bind in Idaho. USDA sets no maximum loan amount, so your ceiling is what your income supports plus the appraisal.
Idaho down-payment assistance that pairs with USDA
The Idaho Housing and Finance Association offers home loans across USDA Rural Development, FHA, VA, and conventional, so USDA pairing is explicit. Its programs allow a purchase with as little as $500 out of your own pocket, and a 620 credit score is beneficial. One useful detail: IHFA's own income eligibility runs up to about $170,000, higher than the USDA cap, so when you pair the two, USDA's limit is the binding one. Confirm current down-payment-assistance terms on the Idaho Housing site.
Idaho USDA requirements at a glance
- Down payment: $0. USDA finances 100% of the price.
- Credit: no hard USDA minimum; 620 to 640 is the practical range, and IHFA looks for 620.
- Income: adjusted household income within $122,800 (1-4) or $162,100 (5-8), statewide, which most Idaho households clear.
- Location: the home must sit outside the Boise, Coeur d'Alene, Idaho Falls, and Pocatello cores; nearly everything else qualifies.
- No first-time-buyer requirement, though it must be your primary residence.
Common questions
What is the 2026 USDA income limit in Idaho?
The 2026 USDA income limit in Idaho is $122,800 for a household of one to four people and $162,100 for five to eight, effective July 13, 2026. Idaho uses this national floor in every county, with no high-cost exceptions, so even Ada County around Boise and the resort counties of Blaine and Teton run at the standard limit.
Do any Idaho counties have a higher USDA income limit than the floor?
No. Idaho is at the national floor of $122,800 for a household of one to four in every county, including Ada, Blaine, and Teton. Some pages assume Boise or the resort counties get higher caps, but they do not. That means the same $122,800 limit applies statewide, which is simpler than in states with metro adjustments.
How much of Idaho is USDA-eligible?
Almost all of it. Idaho is one of the most USDA-friendly states in the country. The only ineligible zones are the urban cores of Boise, Meridian, Nampa, Caldwell, Coeur d'Alene, Idaho Falls, and Pocatello. Everything else, the ring towns and rural counties, is eligible. Combined with incomes under the cap, most of the state can actually use USDA.
Can I use a USDA loan in the Treasure Valley?
Yes, in the ring towns, not the Boise, Meridian, Nampa, or Caldwell cores. Middleton, Emmett, Weiser, Homedale, Parma, Marsing, and New Plymouth are broadly eligible and sit within commuting distance. Star and Kuna have grown fast and are trending toward ineligibility, so verify any address in those two on the USDA map.
Is USDA income based on my gross pay in Idaho?
No. USDA uses your adjusted household income, which is your total household income minus specific deductions such as $480 per dependent, before comparing it to the $122,800 limit. That is different from gross pay, and it is why a household that looks close to the line on paper can still qualify once the deductions are applied.
What credit score do you need for a USDA loan in Idaho?
USDA publishes no hard minimum credit score. In practice, the range is 620 to 640, and the Idaho Housing and Finance Association looks for 620 on its programs. A 640 score clears USDA's automated system most reliably. Below that, a loan can still work through manual underwriting, and individual lenders may add their own overlays.
Can I pair a USDA loan with Idaho Housing assistance?
Yes. The Idaho Housing and Finance Association offers USDA Rural Development loans with down-payment assistance, and its programs can make a purchase possible with as little as $500 out of your own pocket. IHFA's income limit runs higher than USDA's, so USDA's cap is the binding one when you combine them. Confirm current terms with an IHFA lender.
How do you check if an Idaho address is USDA-eligible?
Enter the exact street address into the USDA property eligibility map at eligibility.sc.egov.usda.gov, or use the checker at the top of this page. In Idaho, most addresses outside the Boise, Coeur d'Alene, Idaho Falls, and Pocatello cores qualify, but the fast-growing Treasure Valley towns of Star and Kuna are the exception to check carefully.
