(c) When must the State agency revise the CSFP income guidelines to reflect the annual adjustments of the U.S. Federal Poverty Guidelines? Each year, FNS will notify State agencies, by memorandum, of adjusted income guidelines by household size at 150 percent and 100 percent of the U.S. Federal Poverty Guidelines published annually by HHS. The memorandum will reflect the annual adjustments to the U.S. Federal Poverty Guidelines issued by HHS. The State agency must implement the adjusted guidelines immediately upon receipt of the memorandum.
