Extraordinary Expenses in Child Support: What Counts Beyond Basic Support

Extraordinary Expenses vs. Basic Support

Child support calculations in the United States generally start with a base support obligation that covers the child's fundamental needs: food, shelter, clothing, and basic daily care. This base amount is determined by state child support guidelines and is calculated using each parent's income and the number of children.

However, raising a child involves many costs that go beyond basic necessities. These additional costs are known as extraordinary expenses (also called "add-on expenses," "special expenses," or "work-related childcare expenses" depending on the state). Extraordinary expenses are costs directly related to the child's well-being that are significant enough to warrant separate treatment in the child support calculation.

The distinction matters because basic support is typically paid as a single monthly amount from one parent to the other, while extraordinary expenses are calculated separately and divided between the parents based on their respective incomes. This ensures that both parents contribute to significant child-related costs in a manner that reflects their earning capacity.

The 6 Categories of Extraordinary Expenses

While the specific categories vary by state, most jurisdictions recognize six primary types of extraordinary expenses in child support calculations:

1. Childcare Costs

Work-related childcare is the most commonly awarded extraordinary expense. This includes daycare, after-school care, and summer programs that allow the custodial parent (or both parents) to work or attend school. Courts routinely include these costs because they are a direct consequence of the parent's employment and are necessary for the child's care.

Eligible childcare expenses typically include:

• Full-time daycare for children who are not yet school age
• Before-school and after-school care programs
• Summer day camps and programs when school is not in session
• Babysitting or nanny services during work hours
• Latchkey programs at the child's school

Some states also allow childcare expenses for a parent who is attending school or a job training program, not just for parents who are employed. The childcare provider must generally be licensed or otherwise qualified, and the costs must be reasonable for the area.

2. Health Insurance Premiums

The cost of health insurance premiums for the child is treated as an extraordinary expense in virtually every state. When one parent provides health insurance coverage for the child through their employer or a private plan, the cost of that coverage is factored into the support calculation.

The calculation works as follows: the parent who pays the insurance premium receives a credit equal to the other parent's proportional share of the premium cost. This credit reduces (or increases) the base support payment accordingly. For example, if the noncustodial parent pays $300 per month for the child's health insurance and the custodial parent earns 40% of the combined income, the custodial parent's 40% share ($120) would be deducted from the base support amount.

If both parents have access to employer-provided insurance, the court typically orders the parent with the more affordable or comprehensive coverage to provide it. Under the Affordable Care Act, children can remain on a parent's health insurance plan until age 26, which may extend beyond the child support obligation period in some states.

3. Uninsured Medical Expenses

Uninsured (or unreimbursed) medical expenses are healthcare costs not covered by insurance, including copayments, deductibles, and treatments that insurance does not cover. These expenses are routinely divided between parents as an extraordinary expense.

Common uninsured medical expenses include:

• Orthodontia (braces): Often the single largest uninsured medical expense for children, costing $3,000 to $7,000 or more
• Mental health services: Therapy, counseling, and psychological evaluations not fully covered by insurance
• Prescription medications: Copays and medications not covered by the insurance formulary
• Vision and dental care: Eye exams, glasses, contact lenses, and dental work beyond routine cleanings
• Physical, occupational, or speech therapy: Rehabilitation services, especially for children with special needs
• Emergency room visits: Copays and deductibles from urgent or emergency medical care

Most states require parents to share uninsured medical expenses in proportion to their incomes. Some states set a threshold (such as the first $100 per year) that the custodial parent pays before the sharing arrangement kicks in. Others require the custodial parent to notify the other parent of any non-emergency medical expense above a certain amount before incurring it.

4. Educational Expenses

Educational expenses may be considered extraordinary when they go beyond standard public school costs. Courts are more likely to include these expenses when they address a specific educational need or when the parents agreed to private education during their relationship.

Educational expenses that may be treated as extraordinary include:

• Tutoring: Academic tutoring for children who are struggling in school or need test preparation
• Special education services: Costs for evaluations, accommodations, and specialized instruction for children with learning disabilities, ADHD, or other educational challenges
• Private school tuition: In some states and circumstances, particularly if the child attended private school before the parents separated or if the public schools cannot meet the child's needs
• Testing and assessments: Educational psychological testing, standardized test fees, and similar assessments

Courts are generally cautious about ordering parents to pay for private school tuition. The parent requesting it usually must demonstrate that private education is necessary (not merely preferred) or that the family's lifestyle prior to separation included private schooling.

5. Transportation Costs

Transportation costs between parents' homes can be significant, especially when parents live far apart. Many states allow courts to include travel expenses as an extraordinary expense, particularly when the distance between homes makes regular visitation costly.

Transportation expenses may include:

• Airfare for long-distance visitation
• Gas, tolls, and vehicle wear for extended driving
• Bus, train, or other public transportation costs
• Supervised visitation transportation costs

When parents live in different states, transportation costs can be a major ongoing expense. For guidance on interstate cases, see our article on interstate child support. Courts typically divide transportation costs proportionally to income, though some states assign a greater share to the parent who moved away from the other.

6. Other Expenses That Diminish Basic Support

Some states include a catch-all category for other expenses that significantly reduce the resources available for the child's basic support. This category is applied on a case-by-case basis and may include:

• Life insurance premiums: When a parent is required to maintain life insurance with the child as beneficiary
• Special needs expenses: Costs related to a child's disability that are not covered by insurance or government programs
• Extracurricular activities: In limited circumstances where the activity is unusually expensive or is essential to the child's development

The key criterion is that the expense must be reasonable, necessary, and directly related to the child's well-being. Courts have wide discretion in this category and consider the family's standard of living and each parent's financial resources.

How Extraordinary Expenses Are Divided

The most common method for dividing extraordinary expenses is the proportional income method. Under this approach, each parent pays a share of the extraordinary expense that is proportional to their share of the combined parental income.

Here is how the calculation works:

1. Determine each parent's monthly income: For example, Parent A earns $5,000 per month and Parent B earns $3,000 per month.
2. Calculate each parent's income share: The combined income is $8,000. Parent A's share is 62.5% ($5,000 / $8,000), and Parent B's share is 37.5% ($3,000 / $8,000).
3. Apply the percentages to each extraordinary expense: If childcare costs $800 per month, Parent A's share is $500 (62.5%) and Parent B's share is $300 (37.5%).
4. Adjust the base support: Parent B's $300 share is typically added to the base support amount that Parent A pays, so Parent A effectively pays the childcare provider directly or reimburses Parent B for their share.

Some states use a slightly different approach where extraordinary expenses are included in the child support worksheet itself rather than calculated separately. In these states, the expenses are factored into the overall support formula, and the resulting support amount already accounts for the extraordinary expenses.

In the Worksheet vs. Outside the Worksheet

How extraordinary expenses are handled depends on the state's approach to child support calculations:

• Included in the worksheet: Many states have dedicated lines on the child support worksheet for extraordinary expenses. These expenses are entered directly into the calculation, and the worksheet automatically adjusts the support amount. This is the approach used by states following the Income Shares model, which is the most common model nationwide.
• Outside the worksheet: Some states calculate basic support using the worksheet and then address extraordinary expenses as a separate obligation. Under this approach, the basic support order specifies a monthly amount, and a separate provision requires the parents to share specified extraordinary expenses according to their income ratios.
• By agreement: Parents can agree to handle certain expenses outside of the court-ordered support calculation. For example, parents might agree that one parent will pay for all childcare while the other pays for all medical expenses, as long as the overall arrangement is fair and meets the child's needs.

Courts generally prefer to include as many expenses as possible in the support order to minimize future disputes. However, variable expenses that are difficult to predict (such as uninsured medical costs) are often handled through a separate reimbursement arrangement.

Fixed vs. Variable Expenses

Understanding the difference between fixed and variable extraordinary expenses is important for managing your child support obligation:

• Fixed expenses are predictable and recurring, such as monthly childcare costs, health insurance premiums, and private school tuition. These expenses are easily incorporated into the support calculation because the amount is known in advance.
• Variable expenses fluctuate from month to month, such as uninsured medical costs, tutoring that may be temporary, or transportation costs that vary with visitation schedules. Courts handle variable expenses differently: some order a fixed monthly amount based on estimated costs, while others require periodic accounting and reimbursement.

For variable expenses, the support order should specify how and when reimbursement occurs. Common arrangements include monthly reconciliation, quarterly accounting, or reimbursement within 30 days of receiving a bill or receipt. The order should also specify a threshold for when the sharing obligation begins (for example, expenses exceeding $50 per occurrence).

What Is NOT Considered Extraordinary

Not every child-related expense qualifies as an extraordinary expense in the eyes of the court. The following expenses are generally not treated as extraordinary for child support purposes:

• Cell phones and electronic devices: A child's phone, tablet, or computer is typically considered part of basic support or a gift, not an extraordinary expense
• Designer or brand-name clothing: While children need clothing, expensive or designer brands are considered a lifestyle choice, not a necessity
• Entertainment and recreation: Movie tickets, video games, vacations, and similar entertainment expenses are part of basic parental support
• Pets and pet expenses: Costs associated with a child's pet are not extraordinary expenses
• Routine school supplies: Basic school supplies like notebooks and pencils are part of everyday support
• Allowances: Money given directly to the child is not an extraordinary expense
• Gifts for birthdays and holidays: Gift purchases are considered discretionary parental spending

The guiding principle is that extraordinary expenses must be necessary and directly related to the child's health, education, or welfare. Expenses that reflect parental preference rather than the child's needs are unlikely to be classified as extraordinary.

How Courts Decide Disputes

When parents disagree about whether an expense qualifies as extraordinary, or about the amount of the expense, the court will make a determination based on several factors:

1. Necessity: Is the expense necessary for the child's well-being, or is it discretionary? A child's braces to correct a dental alignment problem are more likely to be deemed necessary than purely cosmetic orthodontia.
2. Reasonableness: Is the cost reasonable given the family's financial circumstances and the local cost of living? Courts compare the expense to average costs in the area.
3. Prior agreement or practice: Did the parents previously agree to share the expense, or did they share similar expenses during their relationship?
4. Ability to pay: Can both parents afford their share of the expense without undue financial hardship?
5. Benefit to the child: Does the expense provide a clear benefit to the child's health, education, or development?

Courts have broad discretion in classifying expenses and determining each parent's share. If you are facing a dispute over extraordinary expenses, documentation is critical. Keep receipts, invoices, and records of all child-related expenses, and maintain written communication with the other parent about significant costs before incurring them.

State-Specific Examples

The treatment of extraordinary expenses varies significantly across states. Here are a few examples:

• California: Uses "add-on" expenses divided proportionally. Mandatory add-ons include childcare costs related to employment and uninsured health expenses. Discretionary add-ons include educational needs and travel for visitation.
• Texas: The guidelines specifically address health insurance and cash medical support. Additional expenses beyond the guideline amount may be ordered based on the proven needs of the child and the parents' ability to pay.
• Florida: Includes childcare costs, health insurance, and uncovered medical/dental expenses as components of the support calculation. The court may also allocate other expenses such as education and transportation.
• New York: The Child Support Standards Act caps basic support as a percentage of parental income. Add-on expenses for childcare, health insurance, and educational expenses are added on top of the basic amount and shared proportionally.
• Illinois: Uses the Income Shares model with specific provisions for childcare, health insurance, extracurricular activities, and school expenses. All "extraordinary" child-related expenses are allocated between parents based on their respective net incomes.
