Idaho Governor Butch Otter signed the Hire One Act into law Wednesdayin a public ceremony.  KTVB.com carried the story with a short video.
The Spokesman-Review also carried an article yesterday that included a short summary of the program:

Under the bill, for-profit Idaho employers who make new hires on or after April 15 – this Friday – would be eligible for a tax credit if the jobs include health benefits and pay at least $12 an hour in counties where employment is above 10 percent, or $15 an hour in counties where it’s below 10 percent. The amount of the credit would vary from 2 to 6 percent of the new worker’s gross wages, based on the employer’s rating in the state unemployment insurance program; that’s to ensure that employers who laid off workers during the recession and are just now hiring them back aren’t rewarded as much as those who kept their workers on, and now are expanding.

The refundable tax credit expires on Jan. 1, 2014.
