Pennsylvania Child Support Guide 2026: How the Guidelines Calculate Your Amount
Parents facing a support case in Pennsylvania usually want one number: how much will the court order? A statewide guideline formula turns both parents’ incomes and the number of children into a presumptive monthly amount. This guide explains how it works. Run your own figures in the free Pennsylvania child support calculator.
How is child support calculated in Pennsylvania?
Pennsylvania adds both parents’ monthly net incomes together, looks up the basic support obligation for that combined income and number of children on the official schedule, then charges the paying parent their percentage share of the total. Child care and health insurance costs are added and split by the same income percentages.
The steps come from Rules 1910.16-2 through 1910.16-6. The “income shares” model estimates what parents in one household would spend on their children, then divides that cost when they live apart — the custodial parent’s share is presumed spent directly on the children.
What is the Pennsylvania child support schedule for 2026?
The Basic Child Support Schedule in Rule 1910.16-3, updated effective January 1, 2026, lists a monthly basic obligation for combined net incomes from $1,300 to $30,000 and one to six children. For example, at $5,000 combined net income the obligation is $1,080 for one child, $1,629 for two, and $1,949 for three.
Above $30,000 combined monthly net income, a formula takes over: the $30,000 amount plus a percentage of the excess — 4.0% for one or two children, up to 6.3% for six.
Does Pennsylvania use gross or net income for child support?
Pennsylvania uses monthly net income. Under Rule 1910.16-2, each parent starts with gross income from all sources — wages, overtime, bonuses, commissions, self-employment, rental income and more — then subtracts items such as federal, state and local taxes, FICA, mandatory union dues and mandatory retirement contributions to reach the net figure the schedule uses.
So two parents on the same salary can owe different amounts — their deductions differ. Bonuses and overtime count too, and an underemployed parent can be assigned an earning capacity.
How much is child support in Pennsylvania for two children?
Take parents earning $5,000 and $3,000 gross per month with two children, $600 of work-related child care and a $250 children’s health premium. Their estimated net incomes are about $3,996 and $2,470, a combined $6,466. The schedule obligation is $1,852, and the higher earner, with 61.8% of the income, pays about $1,670 a month.
Your number moves with each input — higher child care raises it; more overnights with the paying parent can lower it. Courts use actual net figures, not estimates.
Does shared custody reduce child support in Pennsylvania?
Yes, once the paying parent reaches 40% of the annual overnights — 146 nights or more. Rule 1910.16-4(c) then presumes a reduction: the paying parent’s income-share percentage is reduced by the number of points their overnight share exceeds 30%. At 40% of overnights the cut is 10 points; at 50/50 custody it is 20 points.
In an exactly equal arrangement, the higher-income parent is always the payer, and no order may leave the other parent with more than half of the combined net income.
Are child care and health insurance added to Pennsylvania child support?
Yes. Rule 1910.16-6 requires the court to allocate reasonable child care expenses that let a parent work or attend school, and the children’s health insurance premium, between the parents in proportion to their net incomes. These amounts sit on top of the basic obligation, so in higher-cost cases they can add hundreds of dollars a month to the order.
Two details catch parents out: child care totals are reduced by the federal child care tax credit available to the eligible parent, claimed or not; and if the paying parent carries the health coverage, the other parent’s premium share comes off the order instead of being added.
What happens at very low or very high incomes?
At the low end, the guidelines protect a Self-Support Reserve of $1,255 per month for the paying parent. In the schedule’s low-income shaded area, courts compare a calculation using the payer’s income alone with the combined-income calculation and generally award the lower result, so a low-wage parent is not ordered to pay support they cannot survive on.
Above $30,000 combined net, the Rule 1910.16-3.1 formula sets a presumptive minimum, subject to a reasonable-needs review.
Can a Pennsylvania court order more or less than the guideline amount?
Yes. The guideline amount is presumed to be correct, but Rule 1910.16-5 allows deviation when the facts justify it — unusual needs or assets, a child’s extraordinary medical or educational expenses, other support obligations, or the parents’ own written agreement. When a court deviates, it must explain its reasons on the record.
Deviations are the exception — most orders land on the guideline figure, so a careful estimate is a realistic preview of the outcome.
How can you estimate your own Pennsylvania child support?
Start with both parents’ gross monthly incomes, the number of children, your monthly child care cost and the children’s health premium, and enter them in the Pennsylvania child support calculator. It estimates each parent’s net income, applies the 2026 schedule and income shares, and adds the extra costs the way the guidelines do.

Frequently Asked Questions
When does child support end in Pennsylvania?
Generally at age 18 or high school graduation, whichever comes later. It can continue for a child with disabilities, or longer by written agreement.
Can Pennsylvania child support be modified?
Yes. Either parent can petition after a material and substantial change in circumstances — a job loss, a raise, a custody change, or an update to the guideline schedule itself.
Is child support taxable in Pennsylvania?
No. It is not taxable income for the parent who receives it, and the parent who pays it cannot deduct it.
Who pays child support if both parents earn the same?
With primary custody and equal incomes, the non-custodial parent still pays their 50% share — the custodial parent’s share counts as spent directly on the children. With true 50/50 custody and equal incomes, it can fall to almost nothing.
