Financing a LIHTC deal in Illinois
A 9% deal in Illinois competes for IHDA's 2026 ceiling of $43,448,586 (population amount) under the 2026 Low-Income Housing Tax Credit Qualified Allocation Plan. A 4% deal needs an award from the state's $1,717,084,035 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 Illinois's 617 qualified census tracts for 2027 can take the 130% basis boost.
On HUD's records for the 705 Illinois properties on this site's city pages, 12% of those reporting the field were financed with tax-exempt bonds and 78% took 9% (70% present value) credits; 53 received allocations in 2015 or later.
