Who counts in a SNAP household

The short answer

SNAP is built around the idea of a household that shares food, not a family relationship or a lease. Under 273.1(a) there are three kinds of household: a person living alone; a person living with others who customarily buys food and prepares meals for home consumption separately from them; and a group who live together and customarily buy food and prepare meals together. The words that matter are customarily and together. Splitting a grocery bill occasionally or sharing a pizza does not merge two households, but a shared grocery budget and shared cooking does.

Who must be combined whether or not they eat together

Section 273.1(b)(1) lists three groups that must be treated as buying and preparing food with the others they live with, even if they do not. First, spouses. Second, a person under 22 who lives with a natural or adoptive parent or a step-parent. Third, a child under 18, other than a foster child, who lives with and is under the parental control of a household member who is not a parent. The regulation says a child is under parental control if financially or otherwise dependent on a household member, unless state law defines the child as an adult. The age-22 rule catches many young adults who think of themselves as separate: a 21-year-old who lives at home and buys their own groceries is still in their parent’s SNAP household.

The exception for older people who cannot prepare meals

An otherwise eligible person who is 60 or older and cannot purchase and prepare meals because of a permanent disability under the Social Security Act, or a severe, permanent, non-disease-related disability, may be treated, together with a spouse, as a separate household from the people they live with. This is allowed only when the income of the others, not counting the elderly person and spouse, is no more than 165 percent of the poverty line. The 165 percent test is the reason a grandparent living with a higher-earning family may not get separate status.

Boarders, roomers, attendants and foster care

Residents of a commercial boarding house cannot participate. Other people paying a reasonable amount for meals, or for meals and lodging, are boarders and cannot participate independently of the household providing the board; they may join that household only at its request. Reasonable compensation for a boarder arrangement of more than two meals a day is an amount that equals or exceeds the maximum SNAP allotment for the boarder household’s size, and for two meals or fewer, at least two-thirds of that maximum. Someone who pays less than a reasonable amount is treated as a member of the host household. People placed in a home through a government foster care program are treated as boarders. A roomer, who pays for lodging only, and a live-in attendant may each participate as separate households, unless they fall into one of the mandatory combination groups.

People who cannot be members at all

Paragraph (b)(7) lists people who cannot take part as a separate household or as a member of any household, including ineligible noncitizens, ineligible students, people disqualified for work-requirement violations, for failing to provide a Social Security number, or for an intentional program violation, residents of institutions that provide most meals with listed exceptions (such as shelters, federally subsidized elderly housing and certain treatment centers), and people ineligible under the able-bodied adult time limit.

Worked example

Three adults share an apartment. Two are spouses, and the third is a roommate who keeps his own food and cooks separately. The spouses must be one household. The roommate is a separate household because he customarily buys and prepares food apart from them. Now change one fact: the roommate regularly shares meals and groceries with the spouses. The three become a single household, and their combined income and resources are tested together. Change a different fact: the third person is the spouses’ 20-year-old daughter, who buys her own food. She is still part of her parents’ household because she is under 22 and living with them.

Why it matters, and head of household

Household size drives the income limit and the benefit amount, and combining a higher earner into a household can end eligibility. Section 273.1(d) also lets a household choose an adult parent of children, or an adult with parental control, as head of household, and bars the state from using that label to impose special requirements. Strikers are generally not eligible unless the household qualified the day before the strike. For situations the rules do not clearly address, the state may apply its own consistent policy.

Next, compare your numbers with the income limits by household size, and see the student rule and the resource limit.
