1. Pennsylvania Child Support Overview

Pennsylvania's child support system follows the Income Shares Model, which is designed to ensure that children receive the same proportion of parental income that they would have received if their parents lived together.

Key 2025 Updates

  • ✓ Income Shares Model aligned with most U.S. states
  • ✓ Self-Support Reserve protects obligor's basic living expenses
  • ✓ Shared custody threshold at 40% or more custody time
  • ✓ Updated basic support schedules reflecting economic data
  • ✓ Comprehensive healthcare cost integration

Legal Foundation

Pennsylvania child support is governed by:

  • PA Rule 1910.16-2: Calculation of support obligations (Income Shares Model)
  • PA Rule 1910.16-3: Self-Support Reserve
  • PA Rule 1910.16-4: Support guidelines, calculation of net income
  • PA Rule 1910.16-5: Adjustments for shared custody
  • 23 Pa.C.S. § 4322: Pennsylvania Domestic Relations Code

Core Principles

  • Income Shares Model: Both parents' incomes are combined, and support is apportioned based on each parent's proportionate share
  • Self-Support Reserve: Ensures obligor retains minimum income to meet basic needs
  • Net Income Calculation: Deductions for taxes, mandatory retirement, union dues, and certain other expenses
  • Shared Custody Adjustments: When custody time exceeds 40%, support is adjusted proportionally
  • Healthcare and Childcare Costs: Additional expenses are allocated proportionally between parents

2. Quick Reference Data

Parameter2025 Value
Model TypeIncome Shares
Self-Support Reserve (SSR)$1,158/month (2025)
Shared Custody Threshold≥ 40% custody time (146+ overnights/year)
Maximum Combined Income$30,000/month (guideline schedule)
High-Income AdjustmentCourt discretion for combined income > $30,000/month
Low-Income Minimum$50/month (if net income < SSR)
Healthcare AllocationProportional to income share
Childcare AllocationProportional to income share

Note: The Self-Support Reserve (SSR) is adjusted annually based on federal poverty guidelines. For 2025, the SSR is $1,158/month. If the obligor's net income is below this amount, the minimum support obligation is $50/month.

3. Calculation Framework

Pennsylvania's calculation process follows a systematic approach:

Step 1: Determine Gross Income

Gross income includes all income from all sources, including but not limited to:

  • Wages, salaries, bonuses, commissions
  • Self-employment income (gross receipts minus ordinary business expenses)
  • Investment income, rental income
  • Unemployment compensation, workers' compensation
  • Social Security benefits, pensions, retirement income
  • Alimony received from other relationships

Step 2: Calculate Net Income

Net income is determined by deducting from gross income:

  • Federal, state, and local income taxes
  • FICA taxes (Social Security and Medicare)
  • Mandatory retirement contributions
  • Union dues
  • Alimony paid to other relationships (court-ordered)
Net Income = Gross Income − Allowable Deductions

Step 3: Combine Monthly Net Incomes

Add both parents' monthly net incomes:

Combined Net Income = Parent A Net Income + Parent B Net Income

Step 4: Determine Basic Support Obligation

Use the Pennsylvania Child Support Schedule (PA Rule 1910.16-3, Appendix) to find the basic monthly support obligation based on:

  • Combined monthly net income of both parents
  • Number of children

The schedule provides support amounts for combined incomes up to $30,000/month. For higher incomes, the court uses discretion based on the children's needs.

Step 5: Add Additional Expenses

Add additional expenses to the basic obligation:

  • Healthcare expenses: Unreimbursed medical, dental, vision costs
  • Childcare expenses: Work-related childcare costs
  • Private school tuition: If agreed or court-ordered
Total Support = Basic Obligation + Healthcare + Childcare + Other

Step 6: Apportion Support by Income Share

Each parent's share is proportional to their net income:

Parent A Share = (Parent A Net Income ÷ Combined Net Income) × 100%
Parent B Share = (Parent B Net Income ÷ Combined Net Income) × 100%

Each parent's obligation is their proportional share of the total support.

Step 7: Apply Self-Support Reserve (if applicable)

If the obligor's net income is below the Self-Support Reserve ($1,158/month in 2025):

  • The minimum support obligation is $50/month
  • This protects the obligor's ability to meet basic needs

Step 8: Adjust for Shared Custody (if applicable)

If a parent has 40% or more custody time (146+ overnights/year):

  • Calculate each parent's support obligation as if the other parent has primary custody
  • Offset the amounts to determine net support payment

4. Self-Support Reserve Rules

Pennsylvania's Self-Support Reserve (SSR) is a critical protection mechanism that ensures the obligor parent retains sufficient income to meet basic living expenses.

2025 Self-Support Reserve

$1,158 per month

Updated annually based on 125% of the federal poverty guideline for one person

How SSR Works

If Obligor's Net Income ≤ SSR ($1,158/month)

  • Minimum support obligation: $50/month
  • This protects the obligor's ability to meet basic needs
  • Court may consider obligor's ability to pay even this minimum amount

If Obligor's Net Income > SSR but Low

  • Support calculated using income shares model
  • However, support is reduced if payment would bring obligor's income below SSR
  • Obligor must retain at least SSR amount after paying support
Maximum Support = Net Income − SSR

If Obligor's Net Income Significantly Exceeds SSR

  • Full income shares calculation applies
  • No SSR adjustment needed

Important: The Self-Support Reserve does NOT apply to the obligee (custodial parent). It only protects the obligor's (paying parent's) minimum income.

5. Shared Custody Adjustments

Pennsylvania recognizes shared physical custody when a parent has 40% or more custody time (at least 146 overnights per year).

Shared Custody Threshold

40% or more custody time = 146 or more overnights per year

Calculation Method for Shared Custody

Step 1: Calculate Each Parent's Obligation

Calculate support twice — once with each parent as the "obligor":

  • Calculation A: Parent A as obligor (as if Parent B has primary custody)
  • Calculation B: Parent B as obligor (as if Parent A has primary custody)

Step 2: Offset the Obligations

The parent with the higher calculated obligation pays the difference:

Net Support Payment = |Parent A Obligation − Parent B Obligation|

Step 3: Determine Payment Direction

The parent with the higher obligation pays the net amount to the other parent.

Key Points

  • Custody time is measured in overnights, not hours or days
  • Both parents' incomes are considered in shared custody calculations
  • The higher-earning parent typically pays support, even in shared custody
  • Healthcare and childcare costs are still allocated proportionally by income share

Pro Tip: Accurately tracking custody time is critical. Use parenting calendars and detailed custody schedules to document overnights.

6. Calculation Examples

Example 1: Standard Sole Custody Case

Scenario:

  • Parent A (obligor) monthly net income: $4,000
  • Parent B (obligee) monthly net income: $2,500
  • Number of children: 2
  • Custody: Parent B has primary custody
  • Healthcare costs: $200/month
  • Childcare costs: $400/month

Step-by-Step Calculation:

1. Combined Monthly Net Income:

$4,000 + $2,500 = $6,500

2. Basic Support Obligation (from PA schedule):

For $6,500 combined income, 2 children: $1,300/month

3. Total Support (Basic + Healthcare + Childcare):

$1,300 + $200 + $400 = $1,900

4. Parent A's Income Share:

($4,000 ÷ $6,500) × 100% = 61.54%

5. Parent A's Support Obligation:

$1,900 × 61.54% = $1,169

✓ Monthly Support Payment: $1,169

Parent A pays $1,169/month to Parent B

Example 2: Low-Income Case with Self-Support Reserve

Scenario:

  • Parent A (obligor) monthly net income: $1,000
  • Parent B (obligee) monthly net income: $1,800
  • Number of children: 1
  • Custody: Parent B has primary custody
  • Self-Support Reserve (SSR): $1,158

Step-by-Step Calculation:

1. Check SSR:

Parent A net income ($1,000) < SSR ($1,158)

2. Apply Low-Income Rule:

When net income < SSR, minimum support = $50/month

✓ Monthly Support Payment: $50

Parent A pays minimum $50/month due to SSR protection

Note: Without SSR protection, Parent A would be obligated to pay a much higher amount, leaving them below subsistence level. The SSR ensures Parent A retains enough income for basic needs.

Example 3: Shared Custody Case

Scenario:

  • Parent A monthly net income: $5,000
  • Parent B monthly net income: $3,500
  • Number of children: 2
  • Custody: Parent A has 160 overnights/year (43.8%), Parent B has 205 overnights/year (56.2%)
  • Healthcare costs: $250/month

Step-by-Step Calculation:

1. Determine Shared Custody Applies:

Parent A: 160 overnights ≥ 146 → Yes, shared custody

2. Combined Monthly Net Income:

$5,000 + $3,500 = $8,500

3. Basic Support Obligation (from PA schedule):

For $8,500 combined income, 2 children: $1,650/month

4. Total Support (Basic + Healthcare):

$1,650 + $250 = $1,900

5. Calculate Parent A's Obligation (if Parent B had primary custody):

Parent A share: ($5,000 ÷ $8,500) = 58.82%

Parent A obligation: $1,900 × 58.82% = $1,118

6. Calculate Parent B's Obligation (if Parent A had primary custody):

Parent B share: ($3,500 ÷ $8,500) = 41.18%

Parent B obligation: $1,900 × 41.18% = $782

7. Offset Obligations:

$1,118 − $782 = $336

✓ Monthly Support Payment: $336

Parent A (higher income) pays $336/month to Parent B

Key Insight: Even though custody is nearly equal, Parent A still pays support because their income is significantly higher. The shared custody adjustment reduces the payment compared to a sole custody scenario.

7. Frequently Asked Questions

Q1: How often are Pennsylvania child support guidelines updated?

Pennsylvania reviews and updates the child support guidelines every four years. The Self-Support Reserve is adjusted annually based on federal poverty guidelines.

Q2: What if my income changes significantly?

Either parent can petition the court for a modification of child support if there is a significant change in circumstances, such as:

  • Job loss or significant income reduction
  • Substantial income increase
  • Change in custody arrangement
  • Change in healthcare or childcare costs

Q3: Are bonuses and overtime included in income?

Yes. Pennsylvania includes all forms of income, including bonuses, overtime, commissions, and other irregular income. Courts typically average these amounts over a reasonable period (e.g., 12-24 months) to determine a fair monthly income figure.

Q4: Can child support be modified retroactively?

Generally, child support modifications are effective from the date of filing the petition, not retroactively. However, there are exceptions, such as:

  • If the obligor concealed income
  • If there was fraud or misrepresentation

It's critical to file a modification petition as soon as circumstances change.

Q5: What happens if I don't pay child support?

Failure to pay court-ordered child support can result in serious consequences:

  • Wage garnishment
  • Seizure of tax refunds
  • Driver's license suspension
  • Professional license suspension
  • Credit reporting
  • Contempt of court charges (fines or jail time)

Q6: How is self-employment income calculated?

For self-employed parents, income is calculated as:

Self-Employment Income = Gross Receipts − Ordinary and Necessary Business Expenses

Personal expenses are NOT deductible. The court may also impute income if it believes the parent is underreporting income or operating the business inefficiently to avoid support obligations.

Q7: Does remarriage affect child support?

Remarriage alone does not automatically change child support obligations. However:

  • A new spouse's income is generally NOT considered in calculating support
  • If remarriage results in a change in expenses (e.g., shared housing costs), it may indirectly affect support through income calculations
  • If the obligor has additional children with a new spouse, this may be considered in modification proceedings

Q8: When does child support end in Pennsylvania?

Child support typically ends when the child:

  • Turns 18 years old
  • Graduates from high school (if they turn 18 before graduation, support continues until graduation)
  • Gets married
  • Enters military service
  • Is emancipated by court order

Note: Support may continue beyond age 18 if the child has special needs or disabilities.
