Adult child providing financial and/or physical care for aging parent, sandwich generation, career impact.
S-04 models the sandwich-generation household: a peak-earner couple in their late 40s to early 50s, often with kids in late high school or college, who have added an aging parent's financial and care logistics to their own balance sheet. It is the archetype where Form 2441, Medicaid asset look-back, and 529 funding compete for the same dollars.
S-04 exists because the sandwich-generation profile concentrates several specific tax and benefit rules that no other archetype meaningfully exercises together. The aging parent may qualify as a §152(d) qualifying relative dependent (gross-income test under the §151(d)(2) phased exemption, support test, household-membership test), which unlocks dependent-care FSA usage for adult day care, the Credit for Other Dependents, and medical-expense aggregation under §213(a). Simultaneously the household is making the 60-month Medicaid asset look-back decision for the parent's nursing-home eligibility and weighing irrevocable trust transfers against the parent's residual estate. Career interruption — the caregiving daughter's reduced hours, the missed promotion, the early retirement — is the cash-flow shadow that this archetype surfaces and most planning software ignores.
The financial signature is high: median gross income of $176,081, net-worth median of $1.21M, and an 87% homeownership rate (13 of 15) — the latter reflecting both the caregiver household's stability and, often, an inherited or co-owned parental property that the household is maintaining. Liabilities are heavy ($580k median where present): a primary mortgage, frequently a HELOC drawn down against care costs, and student-loan balances that haven't yet been paid off. The 9-of-15 active Education Funding goal plus 9-of-15 Debt Payoff goal is the unique signature — neither S-01 nor S-03 carries that competing-priorities pattern at this wealth tier.
What distinguishes S-04 from neighbouring archetypes is the multi-generational scope of the testing surface. P-03 (dual high-income professionals) and A-03 (early-career dual professionals) share the income band, but the financial software stress test in S-04 is fundamentally different: the household is filing for itself, claiming a parent as a dependent, possibly serving as the parent's Power of Attorney on parent-owned brokerage and bank accounts, and may be a beneficiary on a soon-to-pass-through inherited IRA. The cash-flow drag of paid in-home care or memory-care facility costs ($60k–$120k/year nationally) is structurally similar to childcare in cash-flow shape but tax-treated differently — and the planning horizon is open-ended, unlike a college-graduation date.

Anthony and Lauren are the median S-04 case on income ($176,081) and net worth ($1.26M), with their $580k liability stack essentially a single $577k 2021-vintage 3.4% San Diego mortgage plus a $1,997 credit-card balance and a residual $1,164 student loan (the $1,164 debt-payoff goal is the student loan, on-track). Their one dependent is 4-year-old Amelia — the seed encodes the dependent-child side of the sandwich, while the aging-parent caregiving cost flow is archetype-implied as an overlay rather than itemized on the seed balance sheet, in line with the calibration notes. Retirement ($3.09M target) and education funding ($495k target) are both materially off-track against the income, which is exactly the diagnostic: a working-age peak-earner household stretched between dependent childcare today and the implied aging-parent care costs the archetype models, with no slack to fund either goal on schedule.

Three buyer profiles drive S-04 demand. Wealth-platform engineering teams use it to validate multi-generational planning UX — Power-of-Attorney account linkages, parent-account-overlay views, and pre-inheritance projection scenarios. Tax-software teams test the §152(d) qualifying-relative branch, Form 2441 with adult-care expenses, and the Credit for Other Dependents (Schedule 8812 alternate path). Elder-law and Medicaid-planning fintech teams use the corpus for 60-month asset-transfer look-back simulations, irrevocable-trust funding decisions, and DRA-compliant annuity testing. Employee-benefits platforms covering caregiver-leave policies and elder-care concierge services also test against S-04 to validate eligibility and reimbursement workflows.
S-04 explicitly covers the active-caregiving phase, not the post-loss phase. Once the parent passes and assets transfer, the household moves to E-01 (millennial inheritor) or P-06 (sudden wealth) depending on the magnitude and the household's age. UHNW caregiving — where the parent's estate is the dominant financial event, not the cash-flow drag of care — belongs in H-02 with an overlay rather than here. Caregiving for a disabled child or spouse is X-04 (neurodiverse/disability household), not S-04; the qualifying-relative rules are similar but the planning horizon, ABLE-account eligibility, and special-needs-trust patterns differ. Households where the parent lives in the home but is financially independent (boomerang-parent rather than dependent) are not modeled.
Income and homeownership rates were anchored during v3 synthesis to the AARP Caregiving in the U.S. survey segment matching peak-earner dual-income households, with the eldercare-cost drag informed by Genworth's Cost of Care annual data. The corpus does not encode the specific care setting (in-home aide, adult day care, assisted living, memory care) — buyers needing setting-specific testing should treat that as an overlay. Per CLAUDE.md §9, the v3 corpus is frozen and not regenerable; calibration descriptions reflect synthesis intent rather than auditable quantile fits.
E-01 is the post-loss successor profile: the parent has passed, the inherited IRA's 10-year rule is now active, and the household has transitioned from caregiver to beneficiary.
P-03 (dual high-income professionals) shares the income band but without the multi-generational scope. Reach for P-03 when the planning question is the household's own backdoor Roth, NIIT, and DAF strategies absent eldercare.
X-04 (neurodiverse / disability household) covers caregiving for a member with a disability — ABLE accounts, SNTs, and Medicaid planning around a younger dependent, not an aging parent.
BL-01 (blended family) covers remarriage and step-children planning. Use BL-01 when the diagnostic question is QTIP trusts and beneficiary-conflict; use S-04 when it is the eldercare drag on a peak-earner balance sheet.
S-04 — Caregiver for Aging Parent represents the sandwich-generation household: a peak-earning couple in their late 40s to early 50s simultaneously supporting children and an aging parent. The corpus models the active-caregiving phase with eldercare cost flows, possible §152(d) dependent claims, dependent-care FSA usage for adult care, and career-interruption signals.
Yes, where the §152(d) qualifying-relative tests are met (gross-income, support, relationship). The corpus is calibrated so that a meaningful fraction of households would qualify, exposing tax-software handling of the Credit for Other Dependents and the medical-expense aggregation under §213.
The corpus is shaped to be useful for that testing: the parent's assets are not explicitly enumerated, but the caregiver household's role as Power-of-Attorney holder and the asset-transfer signals are present. Elder-law fintech teams typically layer a parent-asset overlay on top of S-04 households.
S-04 is the pre-inheritance, active-caregiving phase; E-01 is the post-loss successor phase with the 10-year inherited-IRA rule now running and a step-up basis on inherited assets. The same family timeline often passes through S-04 and into E-01 — different testing surfaces, sequenced.
S-04 is tagged for six bundles — B04, B10, B12, B14, B18, and B27 — covering cash-flow stress, family-coverage edge cases, estate planning, behavioral finance, insurance transitions, and life-event coverage.
No. The shipped v3 corpus is frozen and not regenerable from current code (CLAUDE.md §9). Sampler improvements land in a future v4 release with per-archetype golden fixtures in CI to prevent silent drift.
