The full income-limit grid
The numbers below are the maximum annual gross household income at each AMI tier in South Dakota. Read across to see how the ceiling rises with household size; read down to compare the three tiers most federal programs use. The 50% AMI column is the operative ceiling for Section 8 Housing Choice Vouchers and most project-based Section 8 buildings. The 30% AMI column is what most priority programs use — Emergency Housing Vouchers, Continuum of Care permanent supportive housing, Section 811 disability housing, and the 75% set-aside HUD requires for new Section 8 admissions. The 80% AMI column is the broadest ceiling, used by Public Housing, HOME-funded programs, and most state-funded down-payment assistance.

Limits shown are statewide approximations derived from HUD's published state-level Area Median Income and HUD's standard family-size adjustment factors (70/80/90/100/108/116/124/132% for 1- through 8-person households). Actual HUD income limits are published per metro / non-metro county and can be 10–25% higher in high-cost coastal areas. The source is HUD User's Income Limits dataset.
How South Dakota compares
South Dakota's 4-person Area Median Income — the anchor figure HUD uses for every other family-size calculation — is $89,500. That puts South Dakota in the middle of the national distribution. Income ceilings are average, but how those ceilings translate to housing affordability depends heavily on the metro: a renter at 50% AMI in a low-cost city can usually find market-rate housing they can afford, while the same renter in the largest metro will not.
HUD adjusts the 4-person figure for other household sizes using fixed factors. A 1-person household qualifies at 70% of the 4-person limit; a 2-person at 80%; a 3-person at 90%; a 5-person at 108%; a 6-person at 116%; a 7-person at 124%; an 8-person at 132%. For households larger than 8, HUD adds 8 percentage points per additional person.
What counts as "income" in South Dakota
HUD's definition of "annual income" is broad. It counts wages and salaries, self-employment net income, Social Security benefits (including SSI and SSDI), pensions, regular gifts received, child support and alimony actually received, and asset income (interest, dividends, rental income, the imputed return on assets above $50,000). It does not count one-time payments like tax refunds or insurance settlements, the income of household members under 18, the earnings of a live-in aide, food stamps (SNAP), or the first $480 of any earned income from a household member who is a full-time student over 18.
HUD then deducts a standard $480 per dependent and a $525 elderly/disabled household deduction (plus actual childcare and medical expenses above 3% of income for elderly/disabled households) to arrive at "adjusted income" — the figure used to calculate your monthly tenant share of rent (typically 30% of adjusted income).
