How Is Child Support Calculated in Pennsylvania?
How Is Child Support Calculated in Pennsylvania?
When parents separate or divorce, one of the most important financial issues to resolve is child support. In Pennsylvania, child support is calculated using specific statewide guidelines designed to ensure children receive consistent financial support from both parents. Understanding how these calculations work can help you better prepare for what to expect.
At Tullio DeLuca Attorney, we provide legal assistance to the Pennsylvania public in navigating child support matters and protecting parental rights.
Pennsylvania’s Child Support Guidelines
Pennsylvania uses a formula-based system outlined in the Pennsylvania Rules of Civil Procedure. Courts rely on statewide child support guidelines to determine the appropriate amount of support.
The guidelines are based primarily on:
- Each parent’s monthly net income
- The number of children requiring support
- The custody arrangement
- Additional expenses such as healthcare and childcare
The goal is to ensure that children maintain a standard of living similar to what they would have experienced if the parents had remained together.
Determining Each Parent’s Net Income
Child support calculations begin with determining each parent’s monthly net income. This includes:
- Wages and salary
- Bonuses and commissions
- Self-employment income
- Rental income
- Certain benefits, such as workers’ compensation or unemployment
Allowable deductions are then subtracted, including federal, state, and local taxes, Social Security, mandatory retirement contributions, and union dues.
If a parent is unemployed or underemployed without a valid reason, the court may assign an earning capacity instead of using actual income.
Basic Support Obligation
After both parents’ net incomes are determined, the combined income is matched against Pennsylvania’s child support guideline chart. The chart establishes a basic support obligation based on the number of children.
Each parent is responsible for a proportionate share of that amount based on their percentage of the combined income. Typically, the parent with less physical custody pays support to the parent with primary custody.
Custody and Parenting Time Adjustments
Custody arrangements can affect the final support amount. If parents share physical custody and each has the child for a significant amount of time, the court may adjust the support amount accordingly.
Pennsylvania law recognizes that increased parenting time can reduce certain expenses for the primary custodial parent, which may result in a modified support obligation.
Additional Expenses
In addition to the basic support obligation, courts may include additional costs such as:
- Health insurance premiums for the child
- Uninsured medical expenses
- Work-related childcare expenses
- Private school tuition in certain circumstances
These expenses are generally divided between the parents in proportion to their incomes.
Deviations from the Guidelines
While courts usually follow the guidelines, they may deviate in certain cases. Factors that may justify a deviation include:
- Unusual needs or extraordinary expenses of the child
- A parent’s other support obligations
- Significant assets
- Special circumstances affecting fairness
The court must explain the reason for any deviation from the standard formula.
Modifying Child Support Orders
Child support orders are not permanent. If there is a significant change in circumstances—such as a job loss, substantial increase in income, or change in custody—a parent may request a modification.
However, modifications are not automatic. A formal petition must be filed, and the court will review updated financial information before making any changes.
Legal Guidance for Pennsylvania Parents
Child support calculations can become complex, especially when income fluctuates, self-employment is involved, or custody is shared. Ensuring that income is properly calculated and all relevant expenses are considered is critical.
