Participants in the Supplemental Nutrition Assistance Program will see a reduction in benefits due to the expiration of the temporary increase put in place by the federal American Recovery and Reinvestment Act of 2009.  This Friday, most families will see their benefits decrease.  The IDHS informed SNAP recipients of the changes by distributing flyers at local offices and placing notices on its automated helpline, website and social media pages.  Recipients can get the amount of their benefits by calling the number on the back of their Illinois Link card or the IDHS automated helpline at 800-843-6154.  The amount of SNAP benefits each eligible household receives depends on several factors, such as income, household size and expenses.  For households of 1, there will be an $11 difference.  It will be $20 for households of 2, while for households of 3, the difference will be $29 and for those households of 4, it will be $36.
