The federal poverty level is a key consideration in assessing anyone’s eligibility to receive government benefits. Your access to many state and federal safety net programs is often based on where you or your household falls on the
federal poverty guidelines. For example, premiums on the federal health insurance exchange are defined against this metric, as are many forms of tax relief.
Federal Poverty Level Defined
Government programs typically measure households on a sliding scale of incomes against the federal poverty level. For example, a household with an income that earns 100% of the poverty level or less may receive full benefits, while one that earns 300% of the poverty level may receive fewer. Most state and federal programs cap eligibility at 400% of the federal poverty level.
When the federal government refers to “income,” it is referring to
modified adjusted gross income, which is not a number on your tax return. For most people, it’s the same or similar to
adjusted gross income.
A “household” is typically defined based on tax status. Two spouses filing their taxes jointly, for example, would be considered a household of two people. A parent who claims two children as her dependents would be considered a household of three. While there are some exceptions to this rule of thumb, in most cases, household size is defined by the number of people listed on a single tax form.
How and Why Poverty Levels Vary

Both state and federal governments rely on the federal poverty level, which is published by the Department of Health and Human Services (HHS). The agency defines the poverty level based on household size, increasing the cap by $5,140 for each member of the household past the first and adjusting it every year
based on inflation and other factors. Poverty levels, according to the government, vary by location.
In
2024 HHS has set the federal poverty level for all contiguous 48 states, Puerto Rico, the District of Columbia and all U.S. territories, the poverty level is defined as:
Lower 48 States
- Household Size of 1: $15,060
- Household Size of 2: $20,440
- Household Size of 3: $25,820
- Household Size of 4: $31,200
- Household Size of 5: $36,580
- Household Size of 6: $41,960
- Household Size of 7: $47,340
- Household Size of 8: $52,720
For households with more than eight people, add $5,380 per additional member of the household.
