Understanding Tennessee Child Support Calculations

Understanding Tennessee Child Support Calculations

Child support is one of the most important financial issues in any Tennessee divorce or custody case. Whether you are the parent who will be paying support or the parent who will be receiving it, understanding how Tennessee calculates child support can help you plan for the future and ensure your children's needs are met. At Montpelier & Associates in Knoxville, we help parents throughout Knox County and East Tennessee navigate child support matters with confidence.

Tennessee's Income Shares Model

Tennessee uses the Income Shares Model to calculate child support. This model is based on the principle that children should receive the same proportion of parental income that they would have received if the parents lived together. The Tennessee Child Support Guidelines are set forth in TCA § 36-5-101 and the Rules of the Tennessee Department of Human Services, Chapter 1240-2-4.

Under the Income Shares Model, the court first determines each parent's gross income. Gross income includes wages, salaries, commissions, bonuses, overtime pay, self-employment income, rental income, investment income, retirement benefits, and most other sources of recurring income. The court then combines both parents' gross incomes to determine the total combined income.

Using the combined income and the number of children, the court consults the Child Support Schedule — a table published by the state that provides the basic child support obligation (BCSO) for various income levels and numbers of children. Each parent's share of the BCSO is proportional to their share of the combined income.

How Parenting Time Affects Support

The number of overnights each parent has with the child significantly affects the child support calculation. Tennessee's guidelines recognize three parenting time categories:

• Standard parenting time: The alternate residential parent (ARP) has fewer than 93 overnights per year. This results in the highest support obligation for the ARP.
• Extended parenting time: The ARP has between 93 and 182 overnights per year. The support obligation is reduced to reflect the ARP's increased direct spending on the child.
• Equal parenting time: Each parent has between 183 and 365 overnights per year. Support is calculated differently to account for both parents' direct expenditures.

In Knox County custody cases, the parenting time arrangement is often negotiated as part of the permanent parenting plan. Because parenting time directly impacts child support, these two issues are closely related and should be considered together.

Additional Expenses Factored Into Support

Beyond the basic child support obligation, Tennessee's guidelines require the court to consider several additional expenses:

• Health insurance premiums: The cost of adding the child to a parent's health insurance plan is factored into the calculation. The parent who provides insurance receives a credit.
• Uninsured medical expenses: Medical, dental, and vision expenses not covered by insurance are typically divided between the parents in proportion to their incomes.
• Childcare costs: Work-related childcare expenses, such as daycare or after-school care, are added to the basic support obligation and divided between the parents.
• Extraordinary educational expenses: Private school tuition or special education costs may be included if the court finds them appropriate.

Each of these adjustments can significantly impact the final child support amount. An experienced Knoxville family law attorney can help you ensure all relevant expenses are properly accounted for in the calculation.

Deviations from the Guidelines

While the Child Support Guidelines establish a presumptive amount of support, the court has discretion to deviate from the guidelines in certain circumstances. Under the Tennessee guidelines, a deviation may be appropriate when strict application of the guidelines would be unjust or inappropriate. Common reasons for deviation include:

• A child's extraordinary medical or educational needs
• A parent's significant assets or unusually high income
• A parent's legal obligation to support other children from a different relationship
• Travel expenses associated with long-distance parenting time
• The child's own income or assets

If either parent requests a deviation, they must demonstrate that the deviation is in the child's best interest and explain why the standard calculation is inappropriate. The court must make specific written findings to justify any deviation from the guidelines.

Modifying Child Support in Tennessee

Life circumstances change, and Tennessee law allows parents to request a modification of child support when there is a significant variance between the current order and what the guidelines would produce. Under TCA § 36-5-101(g), a modification may be sought if there has been a significant variance — defined as at least a 15 percent change — between the existing support amount and the amount that would result from applying the current guidelines.

Common reasons for seeking a modification include a substantial change in either parent's income (such as a job loss, promotion, or career change), a change in the parenting time schedule, a change in the child's needs, or a change in childcare or health insurance costs. To request a modification in Knox County, you must file a petition with the court and demonstrate the significant variance.

Enforcing Child Support Orders

When a parent fails to pay court-ordered child support, Tennessee law provides several enforcement mechanisms. The Tennessee Department of Human Services, through its child support enforcement division, can take actions such as wage garnishment, intercepting tax refunds, suspending driver's licenses or professional licenses, and reporting the delinquency to credit bureaus.

Additionally, a parent who willfully fails to pay child support can be held in contempt of court under TCA § 36-5-104, which can result in fines and even jail time. If your co-parent is not paying child support as ordered, a Knoxville family law attorney can help you pursue enforcement through the courts.
