Frequently Asked Questions About Child Support in SC
How is child support calculated in South Carolina?
South Carolina uses the Income Shares Model, which combines both parents’ gross incomes and applies the SC Child Support Guidelines to determine each parent’s proportional obligation based on their share of combined income. Adjustments are made for health insurance, childcare, and other qualifying expenses.
How long does child support last in South Carolina?
Child support generally continues until the child turns 18 or graduates from high school, whichever occurs later, but not beyond age 19. The court may also order support for college expenses under certain circumstances pursuant to SC Code § 63-3-530(A)(17).
Can child support be modified in SC?
Yes. Either parent can petition the family court to modify child support if there has been a substantial change in circumstances, such as a significant change in income, job loss, or a change in the child’s needs. The order can also be reviewed if it deviates by more than 15% from the current Guidelines calculation.
What happens if a parent doesn’t pay child support in South Carolina?
A parent who fails to pay court-ordered child support can face contempt of court, wage garnishment, tax refund interception, driver’s license suspension, passport denial, and even jail time in serious cases. The court takes non-payment very seriously.
Does child support cover college expenses in South Carolina?
South Carolina is one of the few states where courts can order a parent to contribute to college expenses. The court considers the child’s academic abilities, the parents’ financial resources, the cost of the college, and the child’s own ability to contribute.
Can a self-employed parent hide income to reduce child support?
Courts closely scrutinize self-employed parents’ finances. The court can examine business records, tax returns, and personal expenses paid through the business to determine true income. If a parent is found to be hiding income, the court may impute income based on earning capacity.
What is imputed income in child support cases?
Imputed income is income that the court assigns to a parent who is voluntarily unemployed or underemployed. If a parent deliberately reduces their income to avoid child support, the court can calculate support based on what that parent could reasonably earn given their education, skills, and experience.
Do I need a lawyer for child support issues in South Carolina?
While not legally required, having an experienced family law attorney can make a significant difference. An attorney can ensure accurate income calculations, advocate for your rights, and help navigate complex issues like self-employment income, imputed income, or modification requests.
If you’re going through a divorce, separation, or custody dispute in South Carolina, one of the most important issues you’ll face is child support.

How South Carolina Approaches Child Support
South Carolina’s child support system is governed by SC Code § 63-17-310 and related statutes. The guiding principle is straightforward: both parents have a legal obligation to financially support their children, regardless of marital status or custody arrangements.
The state uses a formula-based approach known as the Income Shares Model to determine how much each parent should contribute. This model is based on the idea that children should receive the same proportion of parental income they would have received if the family were still intact.
Child support in South Carolina covers:
- Basic necessities — food, clothing, and shelter
- Health insurance and out-of-pocket medical expenses
- Childcare costs related to employment or education
- Educational expenses
- Extracurricular activities (in some cases)
Where Child Support Cases Are Handled
Child support matters in South Carolina are handled by the Family Court. If you live in the Columbia area, your case will likely be heard in Richland County Family Court or Lexington County Family Court, depending on where you reside.
How Child Support Is Calculated in SC
Understanding how child support is calculated in South Carolina is critical for any parent involved in a support case. South Carolina uses the SC Child Support Guidelines, which establish a structured method for determining support amounts.
The Income Shares Model
Here’s a simplified overview of how the calculation works:
- Determine each parent’s gross monthly income — This includes wages, salaries, commissions, bonuses, self-employment income, rental income, retirement benefits, and more.
- Calculate combined gross income — Both parents’ incomes are added together.
- Look up the basic child support obligation — Using the SC Guidelines table, the total obligation is determined based on combined income and the number of children.
- Divide proportionally — Each parent’s share is calculated based on their percentage of the combined income.
- Apply adjustments — Credits are given for health insurance premiums, childcare costs, and other qualifying expenses paid by each parent.
What Counts as “Gross Income”?
South Carolina defines gross income broadly. It includes but is not limited to:
- Salaries and wages
- Commissions and bonuses
- Self-employment income (after legitimate business expenses)
- Rental and investment income
- Social Security benefits
- Workers’ compensation
- Unemployment benefits
- Alimony received from a prior relationship
- Trust income and annuities
What’s excluded: Means-tested public benefits like TANF, SSI, and food stamps are generally not counted as income.
Important: If you’re dealing with a parent who is self-employed or appears to be hiding income, the calculation becomes significantly more complex. Learn more about child support for self-employed parents and how courts handle imputed income in child support cases.
Factors That Affect Your Child Support Amount
While the Guidelines provide a formula, several factors can influence the final amount the court orders:
Custody Arrangement and Parenting Time
The amount of time each parent spends with the child matters. In South Carolina:
- Sole custody arrangements typically result in the non-custodial parent paying support to the custodial parent.
- Shared custody (split parenting) may reduce the non-custodial parent’s obligation if they have the children for a significant number of overnights (generally 109+ overnights per year triggers a shared custody adjustment).
The relationship between child custody in South Carolina and child support is significant — changes in custody often lead to changes in support.
Number of Children
The Guidelines table increases the base obligation as the number of children increases. Support is calculated for all children of the relationship, not per child.
Health Insurance and Medical Costs
The cost of health insurance for the children is factored into the calculation. Typically, the parent who carries the insurance receives a credit. Extraordinary uninsured medical expenses are divided between parents proportionally.
Childcare Costs
Work-related or education-related childcare expenses are added to the basic obligation and divided between the parents based on their income shares.
Extraordinary Expenses
In some cases, the court may consider additional factors such as:
- A child’s special needs or disabilities
- Gifted education programs
- Travel costs for visitation
- Pre-existing support obligations to other children
Establishing a Child Support Order
Child support can be established in several ways in South Carolina:
1. Through a Divorce Proceeding
If you’re going through a divorce in South Carolina, child support is typically addressed as part of the divorce process. The family court will issue a support order along with custody and property division decisions.
2. Through a Custody Action
Unmarried parents can establish child support through a custody and visitation action filed in family court. Paternity may need to be established first if the parents were never married.
3. Through the SC Department of Social Services (DSS)
The SC Department of Social Services Child Support Division can help establish and collect child support, particularly when a parent is receiving public assistance. DSS can locate absent parents, establish paternity, and set up support orders.
4. Through a Consent Agreement
Parents can negotiate a child support amount and submit it to the court for approval. However, the court must verify that the agreed-upon amount meets or exceeds the Guidelines amount, or that there are valid reasons for a deviation.
When Child Support Begins and Ends
When Does Child Support Start?
Child support obligations typically begin on the date the court order is issued. However, in some cases, the court can order retroactive support back to the date the action was filed.
When Does Child Support End?
Under South Carolina law, child support generally ends when the child:
- Turns 18 years old, or
- Graduates from high school, whichever occurs later— but support does not extend beyond age 19 under standard rules
Can Support Continue for College?
South Carolina is one of the few states where the court can order parents to contribute to a child’s college expenses. Under SC Code § 63-3-530(A)(17), the court considers factors like academic performance, the college’s cost, the parents’ finances, and the child’s ability to contribute.
This is a nuanced area of SC law with significant financial implications. Read our detailed guide on child support and college expenses to understand your rights and obligations.
Modifying Child Support in South Carolina
Life changes. And when it does, your child support order may need to change with it. Either parent can petition the court to modify child support if there has been a substantial change in circumstances.
Common reasons for modification include:
- Job loss or significant income reduction (involuntary)
- Substantial increase in income for either parent
- Changes in custody or parenting time
- Changes in the child’s needs (medical, educational, etc.)
- Remarriage (while remarriage alone doesn’t change support, new household income can be a factor in some cases)
- Emancipation of one of multiple children covered by the order
South Carolina also allows for modification review if the current order deviates from the Guidelines by more than 15% when recalculated with current incomes.
Don’t Modify on Your Own: Never simply stop paying or reduce payments without a court order. Even if both parents agree, only a court-approved modification is legally enforceable. Learn the full process in our guide on modifying a child support order.
Income Determination: Complex Cases
Not every child support case involves two W-2 employees with straightforward incomes. Some of the most contested child support disputes in Richland County and Lexington County family courts involve complex income situations.
Self-Employed Parents
When a parent owns a business or works as an independent contractor, determining true income can be challenging. The court examines:
- Business tax returns and profit/loss statements
- Personal expenses run through the business
- Depreciation and other non-cash deductions that reduce taxable income but don’t affect lifestyle
- Lifestyle analysis when reported income seems inconsistent with standard of living
Our detailed guide on child support for self-employed parents explains how the court untangles these financial situations.
Imputed Income
What happens when a parent is voluntarily unemployed or underemployed — perhaps to avoid paying support? South Carolina courts can impute income, meaning they assign an earning capacity to that parent based on:
- Education and training
- Work history and skills
- Job opportunities in the local labor market
- Age and health
Learn more about how courts handle imputed income in child support cases and what evidence you may need.
Child Support and Taxes
Understanding the tax implications of child support is important for both parents:
- Child support payments are not tax-deductible for the paying parent
- Child support received is not taxable income for the receiving parent
- The dependency exemption — Parents can agree on or the court can allocate who claims the child as a dependent for federal tax purposes. This can have significant financial implications.
Tip: Discuss the tax dependency exemption during your child support or divorce negotiations. It can be a valuable bargaining tool.
Deviation from the Guidelines
While the SC Child Support Guidelines create a presumptive amount, the court has discretion to deviate from the guidelines if applying them would be unjust or inappropriate. The court must state its reasons for any deviation on the record.
Factors that may justify deviation include:
- Educational expenses for the child(ren)
- Equitable distribution of property (e.g., one parent received the family home)
- Consumer debts incurred during the marriage
- Alimony obligations
- Significant income disparity
- Agreements between the parents (subject to court approval)
- Child’s own income or assets
- Extraordinary travel expenses for visitation
- The overall best interests of the child
