Here are examples of how SSI is calculated: https://www.ssa.gov/ssi/text-income-ussi.htm

CBPP says that it cost $60 billion in 2020.

SSI is calculated at the person level, or couple if married.

First pass at the computation tree:

• SSI
  • Maximum SSI benefit
  • Marital status
  • Disability status
  • Age
  • State
  • Blindness
  • Number of people in the household
  • Whether the person/couple lives in a non-medical out-of-home facility
  • Whether the person/couple lives in a Medicaid facility
  • Whether home has cooking facilities
  • Total Countable Income
  • Countable unearned income
    • General exclusion (parameter, currently $20/mo)
    • Phase-out rate (parameter, currently 100%)
  • Countable earned income
    • Unused general exclusion (after subtracting from unearned income)
    • Earned income exclusion (parameter, currently $65/mo)
    • Impairment Related Work Expenses (IRWE)
    • Blind Work Expenses
    • Federal, state, and local income taxes
    • Social Security taxes
    • Visual and sensory aids
    • Translation of materials into Braille
    • Professional association fees
    • Union fees
    • Student Earned Income Exclusion (SEIE)
    • Age
    • Regular school attendance
    • Maximum SEIE (parameter, currently $1,930/mo)
    • Phase-out rate (parameter, currently 50%)
  • Plan to Achieve Self-Support (PASS) contribution
  • Asset eligibility
  • Assets
  • Marital status
  • Asset limits (parameter: currently $2,000 for singles, $3,000 for couples)

Do we need a new entity type for this? e.g. named couple which is either an individual or them and their spouse.
