Income Eligibility Tests

Test	Threshold	Source
Initial application	Annual income <= 200% FPIG	55 Pa. Code 3042.31(a)
Between redeterminations	Annual income <= 85% SMI	55 Pa. Code 3042.31(b)
Redetermination	Annual income <= min(235% FPIG, 85% SMI)	55 Pa. Code 3042.31(c)
Asset limit	Family assets < $1,000,000	55 Pa. Code 3042.31(e)
TANF exclusion	Not receiving TANF cash assistance	55 Pa. Code 3042.15(a)
Child age	Under 13 (under 19 if incapable of self-care)	55 Pa. Code 3042.11(b),(d)
Child citizenship	US citizen or lawful permanent resident	55 Pa. Code 3042.36
Residency	Pennsylvania resident	55 Pa. Code 3042.32(a)

New applicants use the 200% FPIG threshold. Currently enrolled families (pa_ccw_enrolled = True) use min(235% FPIG, 85% SMI) at redetermination and 85% SMI between redeterminations.

Income Deductions & Exemptions

Income counted (55 Pa. Code 3042.42): Parent/caretaker, spouse, and children's unearned income. Appendix A Part I lists 21 income types (wages, self-employment, Social Security, pensions, unemployment, workers comp, veterans benefits, child support received, alimony, dividends, interest, rental income, etc.). Implemented via sources.yaml with 16 mapped PolicyEngine variables.

Deductions (55 Pa. Code Appendix A Part II):

Deduction	Rule	Source
Spousal support paid	Court-ordered or voluntary, to person not in household	Appendix A Part II, item A
Child support paid	Court-ordered or voluntary, to person not in household	Appendix A Part II, item B
Medical expenses	Unreimbursed amount exceeding 10% of gross monthly income	Appendix A Part II, item C
Stepparent deduction	Fixed amount by county group (4 groups) and family size (Appendix C)	55 Pa. Code Appendix C

Stepparent Deduction (Appendix C):

County Group	Size 2	Size 3	Size 4	Size 5	Size 6	Each add'l
Group 1 (30 counties incl. Philadelphia, Allegheny, Delaware)	$461	$587	$724	$859	$976	$121
Group 2 (15 counties incl. Cambria, Fayette, Greene)	$406	$532	$662	$791	$894	$121
Group 3 (17 counties incl. Beaver, Washington, Lawrence)	$444	$573	$698	$829	$943	$121
Group 4 (5 counties: Bucks, Chester, Lancaster, Montgomery, Pike)	$481	$614	$749	$885	$1,001	$121

Income exclusions (55 Pa. Code Appendix A Part III): Teen earnings, tax refunds/EITC, SNAP, WIC, foster care payments, student aid, LIHEAP, and ~15 other categories. These are excluded by not including them in the sources.yaml income list.

Income adjustment procedure (55 Pa. Code 3042.43): 8-step process — determine gross income per Appendix A Part I, estimate monthly per conversion table (55 Pa. Code Appendix A), apply stepparent deduction and other deductions, multiply result by 12 for annual adjusted family income.

Copayment

The copayment is weekly, per family (not per child) — 55 Pa. Code 3042.91(c)-(d); CCDF State Plan 3.2.1.

Formula (implemented as rate-based calculation per 55 Pa. Code 3042.98):

weekly_copay = max($5, annual_income * rate / 52)

where:

• rate = 5% if annual income <= 100% FPIG, otherwise 7%
• Minimum copay: $5/week — 3042.98(a)(2)
• Maximum copay: 7% of annual income — 3042.98(a)(3)
• Lower cap for poverty: 5% of annual income if income <= 100% FPIG — 3042.98(a)(4)
• Copay waived for homelessness — 3042.146

Note: Appendix B contains a detailed sliding-fee copayment chart by family size and income bracket. The implementation uses the formula-based 5%/7% rate approach (which closely approximates the chart) rather than encoding all ~1,000 bracket rows. The unused bracket parameter files (copay/chart/) were created but are not referenced by any variable.

Benefit Calculation

Formula (55 Pa. Code 3042.14(b), 3042.92, 3042.118(c)):

monthly_copay = weekly_copay * WEEKS_IN_YEAR / MONTHS_IN_YEAR

max_monthly_payment = sum over eligible children:
    MCCA_daily_rate(region, provider_type, age_group, time_category) * attending_days_per_month

pa_ccw = max(0, min(childcare_expenses - monthly_copay, max_monthly_payment))

• Minimum department payment: $5/week — if department's weekly payment < $5, family is not eligible with that provider (3042.92(c))
• Provider may charge difference above MCCA to family (3042.14(d))

MCCA Rates

Structure: 19 regions x 4 provider types (CENTER, GROUP, FAMILY, R/N) x 5 age groups (Infant, Young Toddler, Old Toddler, Pre-School, School-Age) x 2 time categories (Full-Time, Part-Time).

Rate eras:

• 2025 rates (eff. 2025-01-01): 760 values across 19 region YAML files
• 2023 rates (eff. 2023-03-01): 760 values (2023 chart had 6 age groups including Old School-Age; School-Age and Old School-Age had identical rates, so only 5 age groups are parameterized)

Region mapping: Each PA county maps to one of 19 MCCA regions, encoded via pa_ccw_region using county FIPS codes.

Age group thresholds: Defined in age_group/months.yaml — Infant, Young Toddler, Old Toddler, Pre-School, School-Age based on child's age in months.

Not Modeled

Requirement	Reason
Work requirement >= 20 hrs/week (3042.33(a))	Activity requirements not simulatable in static microsimulation; modeled as pa_ccw_activity_eligible bare input
Teen parent education exemption (3042.33(c)(1))	Not simulatable
Training + work combo (3042.33(c)(2))	Not simulatable
Single parent disability exemption (3042.37(a)-(b))	Not simulatable
Two-parent disability exemption (3042.37(e))	Not simulatable
Provider charges above MCCA (3042.14(d))	Informational — no code needed
Copayment chart bracket lookup (Appendix B)	Approximated by formula-based 5%/7% rate; unused bracket files exist but are not wired to variables
