USDA Rural Development income limits vary by household size in a specific way: everyone in a one-to-four-person household shares the same income ceiling for their county, and everyone in a five-to-eight-person household shares a higher ceiling. Beyond eight people, you add 8 percent of the four-person figure for each additional member.1Rural Development. Single Family Housing Direct Loan Program Income Limits The actual dollar amount depends on your county and on which of the two USDA home loan programs you’re applying for.
How Household Size Changes the Limit
The two-tier structure catches people off guard. A single person living alone is held to the same income ceiling as a family of four in the same county. Add a fifth household member and the ceiling jumps to a higher tier that then covers households of five, six, seven, and eight.
That jump between tiers is meaningful. In some counties it’s several thousand dollars, and it can be the line between qualifying and falling just over. If your household is on the boundary — say, four adults with a baby on the way, or five people with one about to move out — the size you can document at application matters.
Anyone the household considers a resident counts toward the size, including household members who are temporarily absent for work, school, or military service.2Rural Development. HB-1-3555 Chapter 9 – Income Analysis
Direct and Guaranteed Loans Use Different Ceilings
Your county actually has two USDA income limits, and which one applies depends on the program.
The Section 502 Direct Loan, funded and serviced by USDA itself, uses the county’s “low-income limit.” For a four-person household this figure ranges from around $59,000 in lower-cost counties to over $90,000 in higher-cost ones.1Rural Development. Single Family Housing Direct Loan Program Income Limits Direct also uses a “very low income” tier that determines how much payment assistance you receive: the lower your income, the more USDA reduces your effective interest rate.3Rural Development. Single Family Housing Direct Home Loans
The Section 502 Guaranteed Loan, issued by a private lender with a USDA backing, uses the higher “moderate-income limit,” set at 115 percent of the area median family income.4Rural Development. Single Family Housing Guaranteed Loan Program For the 2025 fiscal year, the Guaranteed ceiling for a family of four is $132,850 in the Huntsville, Alabama, metro area and $119,850 in the Anniston-Oxford, Alabama, area.5Rural Development. Single Family Housing Guaranteed Loan Program Income Limits The Guaranteed limit in a given county is almost always higher than the Direct limit for that same county.
Both sets of limits are published for every county and reset each year.
Whose Income Counts
USDA totals income from every adult who lives in the home, not just the people whose names will be on the loan.6eCFR. 7 CFR 3555.152 – Calculation of Income and Assets A spouse who isn’t a co-borrower, a parent living with you, an adult sibling sharing the house — all of their income feeds the household total that gets measured against the limit.
The starting figure is gross wages, salaries, overtime, commissions, tips, and bonuses for all adult household members.7Rural Development. USDA Rural Development HB-1-3555 – Income Analysis On top of that, recurring benefits count: Social Security, disability payments, retirement distributions, alimony, and child support received by anyone in the household. Interest on savings and dividends from investments are added as well.
If a household member is temporarily away, their income still counts. If an adult member is unemployed but actively looking for work, USDA may base their contribution on prior earnings.2Rural Development. HB-1-3555 Chapter 9 – Income Analysis
One useful distinction: this whole-household calculation is called eligibility income and decides whether you qualify. A separate figure called repayment income, which uses only the borrowers’ income, decides how large a loan you can afford.8Rural Development. Determining Repayment Income A non-borrower relative’s paycheck can push you over the eligibility ceiling without helping the size of the loan you can get.
Income That Does Not Count
Federal regulations exclude a meaningful list of income sources from the household total.6eCFR. 7 CFR 3555.152 – Calculation of Income and Assets Applicants who don’t know about the exclusions sometimes count themselves out when they’d actually qualify.
- Foster care and adoption payments, and the income of foster children in the household
- Lump-sum additions such as inheritances, capital gains, insurance settlements, and lump-sum Social Security back payments
- Gifts and temporary, nonrecurring, or sporadic income
- The full amount of any student financial aid
- Earned income tax credits
- Amounts granted for or reimbursing medical expenses
- Income earned by a live-in aide, regardless of who pays them
- SNAP benefits
- Earned income of household members under 18, unless they are an applicant or spouse of one
Full-time students age 18 or older who are not the head of household or their spouse get a partial exclusion: only the first $480 of their earned income counts, and everything above that is excluded.9eCFR. 7 CFR 3550.54 – Calculation of Income and Assets Those students generally don’t have to provide income documentation at all.10Rural Development. HB-1-3555 Attachment 9-A – Income and Documentation Matrix
Deductions That Lower Your Number Before the Comparison
USDA compares your adjusted income against the county limit, not your raw household income. Adjusted income is what remains after specific deductions are subtracted from the annual figure. For a household near the ceiling, these deductions can be decisive.
Dependent Deduction
You subtract $480 for each household member who is under 18, a full-time student age 18 or older, or a disabled adult, as long as that person is not the head of household or their spouse.9eCFR. 7 CFR 3550.54 – Calculation of Income and Assets Three children under 18 means $1,440 comes off the top.
Elderly Household Deduction
If the head of household or their spouse is 62 or older, or is disabled and a party to the loan, the household gets a flat annual deduction. As of August 2025, that deduction is $525, up from $400.11USDA Rural Development. Elderly Family Deduction Increase
Childcare Expenses
Reasonable, unreimbursed childcare costs for children age 12 and under can be deducted when the care lets a household member work or attend school.12Rural Development. Determining Adjusted Income There’s no set cap per child, but the deduction can’t exceed the income earned by the household member whose job the childcare makes possible, and no other adult in the home can be available to provide the care. Save daycare invoices; a lender will want them.
Medical and Disability Expenses
Elderly and disabled households can deduct unreimbursed medical expenses that exceed 3 percent of annual income.13Rural Development. Worksheet for Documenting Eligible Household and Repayment Income Disability-related costs like specialized equipment or attendant care use the same 3-percent floor. Only the portion above the threshold is deductible. On a $40,000 annual income with $3,000 in unreimbursed medical bills, the threshold is $1,200 and the deductible amount is $1,800.
How to Look Up Your County’s Limit
USDA publishes a free lookup tool at eligibility.sc.egov.usda.gov.14USDA Rural Development. Eligibility Pick the program (Direct or Guaranteed), then your state and county. The tool displays the limits broken out by household size and by income tier — very low, low, and moderate.
The tool shows raw limits, not adjusted income. To find out where you actually stand, run your household total through the deductions above. USDA publishes a formal worksheet (Attachment 9-B in the Guaranteed loan handbook) that walks through each deduction line by line.13Rural Development. Worksheet for Documenting Eligible Household and Repayment Income Working through it before you contact a lender gives you a realistic picture.
The Property Also Has to Qualify
Meeting the income limit isn’t enough on its own. The home you want to buy has to sit in an area USDA classifies as rural, a definition tied to population thresholds in the Housing Act of 1949.15Office of the Law Revision Counsel. 42 USC 1490 – Definition of Terms More suburbs qualify than most people expect. The same USDA eligibility site lets you type in a specific address and see whether it’s in an eligible zone,14USDA Rural Development. Eligibility and it’s worth checking the address before you go deep on income paperwork.
