7 C.F.R. § 273.27
(a) When a household leaves TANF, MOE, or a SFCA program, a State agency that has elected this option shall freeze the household's benefit allotment for up to 5 months after making an adjustment for the loss of TANF, MOE, or the SFCA. This is the household's transitional period. To provide the full transitional period, the State agency may extend the certification period for up to 5 months and may extend the household's certification period beyond the maximum periods specified in § 273.10(f). Before initiating the transitional period, the State agency, without requiring additional information or verification from the household, must recalculate the household's SNAP benefit amount by removing the TANF payment, MOE payment, or the SFCA payment from the household's SNAP income. At its option, the State agency may also adjust the benefit to account for:
(1) Changes in household income that it learns about from another State or
Federal means-tested assistance program in which the household participates; or
(b) The State agency must include in its State plan of operation whether it has elected to make these changes:
