County Business Patterns counts private establishments with paid employees in March 2023, while the Quarterly Census of Employment and Wages above counts every unemployment-insured employer, public ones included, as a 2024 annual average, so the two establishment and employment counts differ.

The average approval of $376,739 sits well above the median of $140,000, pulled up by a few larger deals, so the median is the better guide to what a typical borrower here gets. Only 10.1 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.

- Charge-off rate on resolved loans3.3 percent
- Status: Paid in full29

Compare against the national and state SBA charge-off rates, computed the same way over resolved loans only.

The county's own community in the status book, unincorporated Twin Falls County (community 160231), participates in the National Flood Insurance Program and carries no Community Rating System class, so no CRS premium discount applies there. The EPA places Twin Falls County in radon zone 2, a predicted average indoor radon screening level from 2 to 4 pCi/L. The zone is a screening prediction for the county and does not substitute for a test at an address. The best Community Rating System class among the county's communities is 10, which carries a flood insurance premium discount for policies written in that community. 100.0 percent of the county's listed communities participate in the National Flood Insurance Program, per Federal Emergency Management Agency, NFIP Community Status Book (OpenFEMA), as of 2026-09-26.
