Pennsylvania child support amounts are determined by the Income Shares Model under Pa.R.C.P. 1910.16-3, which calculates support based on both parents' combined monthly net income and the number of children. Under the 2026 guidelines effective January 1, 2026, a family with combined monthly net income of $5,000 and two children owes $1,629 per month in basic support, representing a 10% increase from the prior $1,484 figure. The guidelines schedule covers combined incomes from $1,100 to $30,000 per month, with higher earners subject to additional percentage calculations.

How Pennsylvania Calculates Child Support Amounts
Pennsylvania determines how much is child support using a schedule-driven formula rather than a simple percentage of income. Under 23 Pa.C.S. § 4322, the Supreme Court establishes statewide guidelines ensuring similarly situated parents receive consistent treatment. The 2026 guidelines increased basic support obligations by 3% to 10% across all income levels, reflecting updated economic data on child-rearing costs from the U.S. Department of Agriculture.
The calculation follows five distinct steps that produce the final child support amount. First, the court determines each parent's monthly net income by subtracting allowable deductions from gross income. Second, the court combines both parents' net incomes to find a single figure. Third, this combined income is matched against the number of children on the Rule 1910.16-3 schedule to identify the basic support obligation. Fourth, each parent's proportional share is calculated based on their percentage of combined income. Fifth, the court adjusts for additional expenses including childcare, health insurance premiums, and unreimbursed medical costs.
Monthly Net Income Determination
Pennsylvania uses net income, not gross income, as the foundation for child support calculations. Under Pa.R.C.P. 1910.16-2, gross income includes wages, salaries, commissions, bonuses, self-employment earnings, rental income, pension benefits, Social Security payments, and investment returns. The court then subtracts mandatory deductions: federal income taxes, state and local taxes, FICA contributions, mandatory union dues, non-voluntary retirement contributions, and any existing support obligations paid to other households.
For a parent earning $6,500 gross monthly with $1,500 in allowable deductions, the monthly net income equals $5,000. If the other parent has monthly net income of $3,000, the combined monthly net income totals $8,000, which the court uses to reference the support schedule.
2026 Pennsylvania Child Support Schedule Examples
The basic child support schedule under Pa.R.C.P. 1910.16-3 provides specific dollar amounts based on combined monthly net income and number of children. These figures represent the total support obligation before allocation between parents.
| Combined Monthly Net Income | 1 Child | 2 Children | 3 Children | 4 Children |
|---|---|---|---|---|
| $3,000 | $652 | $977 | $1,153 | $1,282 |
| $5,000 | $1,010 | $1,629 | $1,922 | $2,137 |
| $7,500 | $1,390 | $2,163 | $2,553 | $2,839 |
| $10,000 | $1,701 | $2,587 | $3,054 | $3,396 |
| $15,000 | $2,195 | $3,293 | $3,887 | $4,322 |
| $20,000 | $2,584 | $3,876 | $4,575 | $5,087 |
| $30,000 | $2,839 | $4,258 | $5,026 | $5,588 |
For incomes exceeding $30,000 combined monthly net, Pennsylvania applies the $30,000 schedule amount plus a percentage of income above that threshold. For one child, courts add 8.6% of income exceeding $30,000 to the base obligation of $2,839.
Proportional Allocation Between Parents
After identifying the basic support obligation from the schedule, Pennsylvania allocates the amount proportionally based on each parent's share of combined income. The non-custodial parent typically pays their proportional share directly, while the custodial parent fulfills their share through direct expenditures on the child.
Consider parents with combined monthly net income of $8,000, where Parent A earns $5,000 (62.5%) and Parent B earns $3,000 (37.5%). For two children, the schedule obligation is approximately $2,300. Parent A's proportional share equals $1,437.50 (62.5% of $2,300), while Parent B's share equals $862.50. If Parent B has primary custody, Parent A pays $1,437.50 monthly as the child support order amount.
Shared Custody Adjustments Under Pennsylvania Guidelines
When both parents have substantial parenting time, Pennsylvania applies a shared custody formula under Pa.R.C.P. 1910.16-4(c). The 40% overnight threshold triggers this adjustment, recognizing that both households incur duplicated fixed costs for housing, utilities, and furnishings when the child spends significant time in each home.
The shared custody calculation multiplies the basic obligation by 1.5 to account for duplicated expenses, then calculates each parent's proportional share of this adjusted amount. The parent with fewer overnights pays the difference between the two shares. This formula reduces the payment amount compared to a sole custody arrangement because the paying parent already covers substantial direct costs during their parenting time.
For example, if the basic obligation is $1,629 for two children and Parent A has 45% overnights while Parent B has 55%, the adjusted obligation becomes $2,443.50 (1.5 x $1,629). After calculating proportional shares and offsetting, the payment amount decreases significantly compared to the sole custody calculation.
Additional Child Support Expenses in Pennsylvania
Beyond the basic support obligation, Pennsylvania courts allocate additional child-related expenses proportionally between parents. Under Pa.R.C.P. 1910.16-6, these expenses include childcare costs necessary for employment or education, health insurance premiums attributable to the child, unreimbursed medical expenses exceeding $250 annually, private school tuition when agreed upon, and extracurricular activity costs deemed reasonable.
Childcare expenses are added directly to the basic support obligation and divided proportionally. If monthly daycare costs $1,200 and Parent A earns 60% of combined income, Parent A contributes $720 toward childcare in addition to their basic support share. Health insurance premiums for the child follow the same proportional allocation, with the parent carrying coverage receiving credit or reimbursement from the other parent.
Pennsylvania Self-Support Reserve Protection
Pennsylvania protects low-income obligors through the self-support reserve, which increased to $1,255 per month under the 2026 guidelines from the previous $1,063 threshold. This 18% increase provides additional protection ensuring paying parents retain sufficient income for basic subsistence needs including housing, food, and transportation.
If paying the full guideline amount would reduce the obligor's net income below $1,255 monthly, the court reduces the support obligation accordingly. For an obligor with $2,000 monthly net income and a calculated obligation of $900, the court may reduce the order to preserve the $1,255 minimum. The self-support reserve does not eliminate the obligation entirely but caps it at a level allowing the obligor to maintain basic living standards.
How to Calculate Your Pennsylvania Child Support Amount
Pennsylvania provides free official tools for calculating child support amounts. The Department of Human Services maintains a Child Support Estimator at humanservices.dhs.pa.gov that applies current guidelines automatically. Parents enter their monthly net incomes, number of children, custody arrangement, and additional expenses to receive an estimated support amount.
To calculate manually using the 2026 schedule:
- Determine each parent's monthly gross income from all sources recognized under Pa.R.C.P. 1910.16-2
- Subtract allowable deductions (taxes, FICA, mandatory retirement, existing support orders) to find net income
- Add both parents' net incomes for combined monthly net income
- Locate the combined income row and number of children column on the Rule 1910.16-3 schedule
- Calculate each parent's percentage of combined income
- Multiply the basic obligation by the non-custodial parent's income percentage
- Add proportional shares of childcare, health insurance, and other additional expenses
The resulting figure represents the monthly child support order before any shared custody adjustments or deviation factors.
Modifying Child Support Orders in Pennsylvania
Either parent may petition for modification when a material and substantial change in circumstances occurs. Under Pa.R.C.P. 1910.19, qualifying changes include job loss, significant income increase or decrease, change in custody arrangement, new childcare needs, or changes in the child's medical requirements. Notably, the 2026 guidelines update itself qualifies as a material change, allowing either parent to request recalculation under the new schedule without proving any other circumstance change.
Pennsylvania charges no filing fee for support modifications, distinguishing it from many other states that impose $50-$150 modification fees. Parents can file online through the E-Services portal at childsupport.pa.gov or submit paper petitions to the county Domestic Relations Section. After filing, the Domestic Relations office schedules a modification conference where both parents provide updated income documentation and a conference officer applies current guidelines to recommend a new amount.
The modification process typically takes 30-60 days from filing to new order entry. Courts can modify support retroactively to the petition filing date, meaning delays in processing do not prejudice either party. However, modifications cannot be applied retroactively beyond the filing date, emphasizing the importance of filing promptly when circumstances change.
Pennsylvania Child Support Enforcement Mechanisms
Pennsylvania maintains robust enforcement mechanisms through the Child Support Enforcement System (PACSES), which collected nearly $1.1 billion in child support during federal fiscal year 2023 and achieved an 82% collection rate on current support due, substantially exceeding the 65% national average.
All Pennsylvania support orders include immediate wage withholding provisions requiring employers to deduct support amounts plus any arrears payments and forward funds directly to the State Collection and Disbursement Unit. This automatic mechanism prevents accumulation of missed payments and ensures consistent support delivery.
When obligors fall behind, Pennsylvania employs escalating enforcement tools:
- Income tax refund interception (state and federal)
- Lottery prize offset for winnings exceeding $600
- Driver's license suspension through PennDOT
- Professional license suspension (medical, law, real estate, and other regulated professions)
- Passport denial for arrears exceeding $2,500
- Bank account seizure and property liens
- Credit bureau reporting affecting credit scores
- Contempt proceedings with potential incarceration
Contempt Penalties for Non-Payment
Willful failure to pay child support constitutes contempt of court under Pennsylvania law. Civil contempt can result in incarceration for up to six months, fines up to $1,000, and probation periods up to one year. Courts impose a 10% surcharge on payments outstanding for 30 or more days, adding financial penalties to the arrears balance.
A parent demonstrating inability to pay due to genuine circumstances such as job loss, disability, or incarceration will not be held in contempt. However, the obligation continues accruing during periods of non-payment, and courts expect obligors to seek modification promptly rather than simply failing to pay. Criminal contempt charges may apply in egregious cases, potentially resulting in misdemeanor or felony prosecution and state prison sentences.
The Bureau of State Child Support Enforcement provides assistance at 1-800-932-0211, and each county's Domestic Relations Section handles local enforcement actions. Parents owed support can request enforcement assistance without attorney representation, though complex cases may benefit from legal counsel.
When Child Support Ends in Pennsylvania
Pennsylvania child support obligations terminate when the child reaches age 18 or graduates from high school, whichever occurs later, with a maximum age of 19 under 23 Pa.C.S. § 4321. Support orders do not terminate automatically. The paying parent must file a petition to terminate or request closure through the Domestic Relations Section after the qualifying event.
Six months before a child turns 18, the Domestic Relations Section issues an emancipation inquiry to the custodial parent. If the inquiry is not returned within 30 days or the parties reach no agreement regarding continued support, the office may administratively terminate the charging order. Arrears accrued through the termination date remain enforceable regardless of the child's subsequent emancipation.
Exceptions to Standard Termination
Children may become emancipated before age 18 through marriage, military enlistment, or establishing genuine financial independence and a separate household. Courts evaluate emancipation claims carefully, and the paying parent bears the burden of demonstrating the child has severed financial dependence on both parents.
Adult children with physical or mental disabilities preventing self-support may remain eligible for continued support under 23 Pa.C.S. § 4321(3). The disability must have existed before the child turned 18 or originated during that period. Support for disabled adult children continues indefinitely based on ongoing need and parental ability to pay.
College Expenses and Post-Secondary Support
Pennsylvania courts cannot order parents to contribute to college expenses absent a prior written agreement. The Pennsylvania Supreme Court declared 23 Pa.C.S. § 4327, which had authorized court-ordered post-secondary support, unconstitutional as violating equal protection in Curtis v. Kline. Parents may voluntarily agree to post-secondary support provisions in separation agreements or consent orders, and those contractual obligations remain enforceable. Without such an agreement, the statutory support obligation ends at high school graduation or age 18/19, regardless of college enrollment.
Pennsylvania Divorce Filing Fees and Court Costs
While child support cases can proceed independently of divorce, many families address support during divorce proceedings. Pennsylvania divorce filing fees range from $135 to $388 depending on county, with Philadelphia County charging $333.73, Bucks County at $388, and Franklin County at $168.50 as of March 2026. Additional costs include service of process ($50-$125), certified copies ($10-$25 per document), and hearing fees ($25-$75).
Fee waivers are available through the Petition to Proceed In Forma Pauperis for households with income at or below 125% of federal poverty guidelines. For 2026, a single-person household earning approximately $19,563 or less may qualify for waiver of all court costs.

Frequently Asked Questions About Pennsylvania Child Support
How much is child support in Pennsylvania for one child?
Pennsylvania child support for one child typically ranges from $652 to $2,839 per month depending on the parents' combined monthly net income under the 2026 guidelines. At $5,000 combined income, the basic obligation is $1,010. At $10,000 combined income, it increases to $1,701. The non-custodial parent pays their proportional share based on income percentage.
What percentage of income goes to child support in Pennsylvania?
Pennsylvania does not use a flat percentage formula. However, the guidelines generally allocate approximately 17% of combined net income for one child, 25% for two children, 29% for three children, and 31% for four children. Individual obligations depend on each parent's income share and custody arrangement.
Can child support be modified if I lose my job in Pennsylvania?
Yes, job loss constitutes a material and substantial change in circumstances under Pa.R.C.P. 1910.19, entitling either parent to petition for modification. Pennsylvania charges no filing fee for modifications. File promptly because courts cannot reduce support retroactively before the petition date. Interim employment documentation and job search efforts may be required.
Does Pennsylvania consider the new spouse's income for child support?
No, a new spouse's income is not included in child support calculations under Pennsylvania guidelines. Only the biological or adoptive parents' incomes determine support obligations. However, if a new spouse's income allows the obligor to reduce personal living expenses, courts may consider household circumstances when evaluating ability to pay.
How long does child support last in Pennsylvania?
Child support in Pennsylvania continues until the child turns 18 or graduates from high school, whichever occurs later, with a maximum age of 19. Support may continue indefinitely for children with disabilities preventing self-sufficiency. College expenses are not included unless parents contractually agreed to post-secondary support.
What happens if child support is not paid in Pennsylvania?
Pennsylvania enforces unpaid child support through wage garnishment, tax refund interception, driver's and professional license suspension, passport denial, bank account seizure, and contempt proceedings. Civil contempt can result in up to six months' incarceration, $1,000 in fines, and a 10% surcharge on overdue amounts.
Can I get child support without a custody order in Pennsylvania?
Yes, Pennsylvania allows parents to establish child support orders independently of custody proceedings. Either parent can file a support complaint with the county Domestic Relations Section regardless of marital status or formal custody arrangement. The support order will reflect the existing informal custody arrangement or assume the filing parent has primary physical custody.
How does shared custody affect child support in Pennsylvania?
When each parent has at least 40% overnight parenting time, Pennsylvania applies a shared custody formula that reduces the payment amount. The basic obligation is multiplied by 1.5 to account for duplicated household costs, and each parent's share is calculated proportionally. The parent with fewer overnights pays the difference between shares.
Does child support cover health insurance in Pennsylvania?
Health insurance premiums for the child are allocated proportionally between parents in addition to the basic support obligation. The parent providing coverage receives credit or reimbursement from the other parent based on income percentages. Unreimbursed medical expenses exceeding $250 annually are also divided proportionally.
Can child support be waived in Pennsylvania?
Parents cannot permanently waive child support in Pennsylvania because support is a right belonging to the child, not the parents. Courts will not approve agreements eliminating support obligations. However, parents with relatively equal incomes and shared custody may calculate to minimal or zero transfer amounts under the guidelines formula.
