Under the FairTax, family households of lawful U.S. residents would be eligible to receive a "Family Consumption Allowance" (FCA) based on family size (regardless of income) that is equal to the estimated total FairTax paid on poverty level spending according to the poverty guidelines published by the U.S. Department of Health and Human Services. The FCA is a tax rebate (known as a "prebate" as it would be an advance) paid in twelve monthly installments, adjusted for inflation. The rebate is meant to eliminate the taxation of household necessities and make the plan progressive. Households would register once a year with their sales tax administering authority, providing the names and social security numbers of each household member. The Social Security Administration would disburse the monthly rebate payments in the form of a paper check via U.S. Mail, an electronic funds transfer to a bank account, or a "smartcard" that can be used like a debit card.
