The household's monthly allotment shall equal the thrifty food plan for the household's size reduced by 30 percent of the household's net monthly income as calculated in Regulation .43 of this chapter. Calculation. The local department shall: Round up the product of 30 percent times the household's net income to the next whole dollar if it ends in 1 through 99 cents; and Round up to $2, $4, or $6, respectively, if an allotment of $1, $3, or $5 results. Prorating Benefits. The local department shall prorate benefits for an initial month from the day the calculation is required to begin according to Regulation .14I or .18B and C of this chapter, to the end of the month. A household applying on the 31st of a month shall be treated as though it applied on the 30th of the month. The following formula may be used to calculate the initial monthly allotment: If the calculation of the initial monthly allotment yields an allotment of less than $10 for the household, a benefit may not be issued for the initial month. Except during an initial month, all eligible one and two member households shall receive a minimum monthly allotment of $16, and all eligible households with three or more members that are entitled to $1, $3, or $5 allotments shall receive allotments of $2, $4, or $6, respectively. Other than households described in §F of this regulation, an eligible household with three or more members, which is not entitled to benefits except for the proration requirements of §C of this regulation and the provision precluding issuance of less than $10 in an initial month in accordance with §D of this regulation, the local department shall deny the household's application because its net income exceeds the level at which benefits are issued. A household that files a joint public assistance-FSP application and is categorically eligible in accordance with Regulation .12 of this chapter after being denied non-PA benefits shall have its benefits for the initial month prorated from the date from which the public assistance is payable or the date of the original FSP application, whichever is later.
