Basis boost areas: 2027 QCTs and DDAs
HUD's 2027 lists, which apply from January 1, 2027, put 34 Idaho census tracts in qualified census tracts, spread across 11 counties. 4 nonmetropolitan counties are difficult development areas. In metro areas, 7 ZIP code areas (ZCTAs) are Small Area DDAs. A building in either can take 130% of eligible basis. Check an address with the QCT and DDA lookup.
| County | 2027 QCT tracts |
|---|---|
| Canyon County | 9 |
| Ada County | 6 |
| Bannock County | 6 |

Nonmetro DDA counties: Blaine County, Bonner County, Elmore County, Shoshone County.
Metro areas with Small Area DDAs: Boise City, ID HUD Metro FMR Area; Gem County, ID HUD Metro FMR Area; Idaho Falls, ID HUD Metro FMR Area.
Every Idaho qualified census tract, with its population, poverty rate and median income, is on the Idaho QCT list by county.

Financing a LIHTC deal in Idaho
A 9% deal in Idaho competes for IHFA's 2026 ceiling of $6,933,568 (population amount) under the Low-Income Housing Tax Credit Program Qualified Allocation Plan for the State of Idaho (2026 Final QAP). A 4% deal needs an award from the state's $397,625,000 private activity bond cap: tax-exempt bonds must finance 50% of the aggregate basis of the building and land, or at least 25% if one or more of those bonds, from an issue dated after December 31, 2025, together finance at least 5% of that basis (the 25% bond test, for buildings placed in service in taxable years beginning after December 31, 2025). Sites in Idaho's 34 qualified census tracts for 2027 can take the 130% basis boost.
On HUD's records for the 160 Idaho properties on this site's city pages, 5% of those reporting the field were financed with tax-exempt bonds and 88% took 9% (70% present value) credits; 29 received allocations in 2015 or later.
