Pennsylvania Child Support Guidelines

Pennsylvania operates under the Income Shares model, one of 42 U.S. states using this framework. For a parent supporting one child, the base guideline applies roughly 18% of income, scaling to 26% for two children and 32% for three. That places Pennsylvania at rank #18 of 51 states by single-child base percentage. The state caps countable income at $30,000 per month, meaning earnings above that threshold fall to judicial discretion rather than the formula. Median household income across Pennsylvania is $68,957 annually, which shapes the real-world dollar obligations families face under these percentages.

On the enforcement side, the Pennsylvania child support program manages 569,000 active cases and collected approximately $1,200 million in the most recent OCSE reporting year. The state's collection rate of 61.9% compares to a national average of 60.6% across reporting states — placing Pennsylvania at rank #23 of 51 on collection efficiency, and rank #7 by caseload volume (national average: 285,686 cases per state). Paternity is established in 95.8% of Pennsylvania cases, compared to 94.9% nationally — a critical step because child support orders cannot be enforced without legal parentage on record. Orders are in place for 76.5% of the caseload.

Context matters when interpreting these numbers. A higher percentage-of-income figure does not automatically mean higher dollar obligations — the underlying income brackets, deductions, parenting-time adjustments, and self-support reserves vary meaningfully between states. Pennsylvania allows a parenting time adjustment, which can materially reduce the base obligation when the non-custodial parent exercises substantial overnight time.
