Tennessee Child Support: Complete Calculation & Enforcement Guide (2024)

Last Updated: January 2024 | Tennessee Code Annotated Title 36, Chapter 5

Child support is one of the most important financial obligations parents face after separation or divorce. In Tennessee, child support is calculated using the Income Shares Model, which considers both parents' incomes to determine their proportional responsibility for their children's financial needs.

This comprehensive guide explains how Tennessee child support is calculated, when and how to modify orders, what enforcement options exist, how income withholding works, and what happens when payments fall into arrears.

Quick Answer: Tennessee uses an Income Shares Model for child support calculations, meaning both parents' incomes are combined to determine the total child support obligation, which is then divided between parents based on their respective incomes. The Tennessee Department of Human Services (DHS) oversees child support services and provides official calculators and guidelines.

Understanding Child Support in Tennessee

Child support is a financial obligation that parents owe to their children, regardless of marital status. In Tennessee, both parents have a legal duty to support their children financially. The child support system is designed to ensure that children receive adequate financial support from both parents, maintaining their standard of living as much as possible after separation or divorce.

The Purpose of Child Support

Tennessee child support serves several important purposes:

Basic needs: Food, clothing, and shelter
Medical expenses: Health insurance premiums and uninsured medical costs
Educational expenses: School fees, supplies, and extracurricular activities
Childcare costs: Work-related daycare and babysitting expenses
Standard of living: Maintaining consistency between households when possible

Who Pays Child Support in Tennessee?

In Tennessee, the parent who spends less time with the child (typically the non-custodial parent) generally pays child support to the parent who has primary residential parenting time. However, in shared parenting arrangements (approximately equal time), child support calculations become more complex and may result in either parent paying support, depending on income disparities.

Legal Framework

Tennessee child support is governed by:

Tennessee Code Annotated Title 36, Chapter 5 (Domestic Relations)
Tennessee Department of Human Services (DHS) Child Support Services
Tennessee Supreme Court Child Support Guidelines
Local court rules and practices

The Tennessee Income Shares Model

Tennessee uses the Income Shares Model for calculating child support obligations. This model is based on the principle that children should receive the same proportion of parental income they would have received if the parents lived together.

How the Income Shares Model Works

The Income Shares Model follows these steps:

Determine both parents' gross incomes
Combine the incomes to find the total household income
Consult the Tennessee Child Support Schedule to find the total support obligation for the combined income level and number of children
Calculate each parent's percentage of the combined income
Allocate the total obligation between parents based on their income percentages
Adjust for parenting time (residential time with each parent)
Add expenses such as health insurance premiums, work-related childcare, and extraordinary medical expenses

Why Tennessee Uses Income Shares

The Income Shares Model reflects several policy goals:

Shared responsibility: Both parents contribute proportionally to their children's financial needs
Continuity of lifestyle: Children maintain a standard of living similar to what they would have experienced in an intact household
Fairness: Support obligations are based on actual ability to pay
Transparency: The calculation method is consistent and predictable

How Tennessee Child Support Is Calculated

Understanding the calculation process is essential for both parents anticipating child support obligations. The Tennessee Department of Human Services provides an official Child Support Calculator that automates this process.

Step 1: Determine Gross Income

Tennessee law defines "gross income" broadly under T.C.A. § 36-5-101. Gross income includes:

Included Income Sources:

Salaries and wages (before deductions)
Self-employment income
Bonuses and commissions
Overtime pay (when consistent)
Tips
Disability benefits
Workers' compensation
Unemployment benefits
Social Security benefits (except SSI)
Veterans' benefits
Pension and retirement distributions
Annuities
Trust income
Interest and dividends
Rental income
Capital gains
Gifts (especially regular or substantial gifts)

Potential Income (Imputed Income):

Tennessee courts may "impute" income to a parent who is:

Voluntarily unemployed or underemployed
Capable of working but choosing not to
Intentionally reducing income to avoid support obligations
Hiding income sources

When imputing income, courts consider:

Recent employment history
Education and training
Job opportunities in the area
Prevailing wages for available positions
Physical and mental capabilities

Step 2: Combined Adjusted Income

Once both parents' gross incomes are determined, they are combined to reach the Total Adjusted Gross Income. This figure is used to consult the Tennessee Child Support Schedule.

Step 3: Consult the Tennessee Child Support Schedule

The Tennessee Child Support Schedule is a statutory table that establishes the basic child support obligation based on:

Combined parental income
Number of children requiring support

The schedule reflects studies of actual household spending on children at various income levels in intact families.

Example from Tennessee Child Support Schedule:

Combined Monthly Income	1 Child	2 Children	3 Children
$2,000	$449	$576	$636
$4,000	$713	$981	$1,137
$6,000	$946	$1,321	$1,561
$8,000	$1,147	$1,625	$1,945
$10,000	$1,335	$1,905	$2,299

Note: These figures are illustrative. Consult the official Tennessee Child Support Schedule for accurate amounts.

Each parent's percentage share of the combined income determines their share of the total child support obligation.

Example:

Parent A's monthly income: $4,000
Parent B's monthly income: $2,000
Combined income: $6,000
Parent A's share: 67% ($4,000 / $6,000)
Parent B's share: 33% ($2,000 / $6,000)

Step 5: Adjust for Parenting Time

The residential schedule (parenting time) affects the final calculation:

Primary Residential Parent (PRP) Scenario:

One parent has the child more than 50% of the time
Child support is calculated and typically paid by the non-residential parent
Minor adjustments may apply for extended visitation time

Shared Parenting Scenario (Approximately Equal Time):

Both parents have 92-182 nights per year with the child
The "obligor" (parent who would pay under the basic calculation) receives a credit for parenting time
A residential parenting time adjustment is applied using the Tennessee worksheet

Step 6: Add Additional Expenses

Several additional expenses are added to or considered in the basic child support obligation:

Health Insurance Premiums:

The parent paying for the child's health insurance receives a credit
This credit is typically added to the basic support obligation
Only the child's portion of the premium is considered

Work-Related Childcare:

Reasonable childcare expenses necessary for a parent to work or attend school
Typically divided between parents based on income proportions
May be capped at reasonable market rates

Extraordinary Medical Expenses:

Uninsured medical expenses over a specified threshold (typically $250 per child per year)
Usually prorated between parents based on income percentages
Includes orthodontics, prescriptions, co-pays, and other healthcare costs

Educational Expenses:

Private school tuition (if agreed upon or court-ordered)
Special education expenses
Extracurricular activity fees

Tennessee Child Support Guidelines

The Tennessee Department of Human Services (DHS) provides comprehensive child support guidelines that govern how child support is established, modified, and enforced.

The Tennessee Child Support Schedule

The Child Support Schedule is reviewed and updated periodically by the Tennessee Department of Human Services. The schedule is based on:

Economic studies of family spending patterns
Cost of living data specific to Tennessee
Federal child support guidelines requirements
Public policy considerations

Parenting Time Adjustments

Tennessee recognizes different parenting time arrangements:

Table 1: Primary Residential Parent Adjustments

Used when one parent has fewer than 92 nights per year with the child
Standard calculation with minimal adjustments

Table 2: Shared Parenting Adjustments

Used when both parents have 92-182 nights per year
More complex calculation involving parenting time credit
Designed to account for the additional direct expenses of the parent spending more time with the child

Self-Employment and Business Income

Calculating child support for self-employed parents involves additional considerations:

Reasonable business expenses are deducted from gross business income
Personal expenses disguised as business expenses may be added back
Depreciation may be added back to income
Prior years' income may be considered to account for fluctuations
Business seasonality is considered when appropriate

Overtime and Bonus Income

Tennessee courts generally handle irregular income as follows:

Consistent overtime: Included as regular income
Occasional overtime: May be averaged over time
Bonuses: Prorated or added to base income
Commission income: May be averaged based on history
Decline in income: Requires proof that reduction is involuntary

Deviation from Child Support Guidelines

While Tennessee courts generally follow the Child Support Guidelines, deviations are permitted under certain circumstances specified in T.C.A. § 36-5-101.

Mandatory Deviation Factors

The court must deviate from the guidelines when application would be unjust or inappropriate. Factors include:

Special needs children: Extraordinary medical, psychological, or educational needs
High income families: The guidelines may not accurately reflect needs at very high income levels
Low income families: The obligor's ability to pay may be limited
Extended visitation: Significant parenting time that reduces the residential parent's expenses
Children from multiple relationships: Fair allocation of support responsibility
Geographical considerations: Long-distance parenting arrangements
Age of children: Older children may have different financial needs
Historical spending patterns: Established spending on children before separation

Percentage of Income Method

In cases where the Income Shares Model is impractical (typically very high or very low income cases), Tennessee courts may use the Percentage of Income Method as an alternative:

Approximate Guidelines:

1 child: 21% of obligor's income
2 children: 29% of obligor's income
3 children: 34% of obligor's income
4+ children: 38% of obligor's income

Documenting Deviations

When deviating from guidelines, Tennessee courts must:

Make written findings explaining the deviation
Specify how the deviation serves the child's best interests
Document the specific factors justifying the deviation
State the guideline amount and the deviated amount

Modifying Child Support in Tennessee

Child support orders are not permanent. They can and should be modified when circumstances change significantly. The Tennessee Department of Human Services provides review and adjustment services for both parents.

When Can Child Support Be Modified?

Under Tennessee law, a child support order may be modified when there has been a significant variance from the guidelines resulting from a substantial and material change in circumstances.

Common qualifying circumstances include:

Income changes:

Job loss or reduction in hours
Significant increase in income
Promotion or demotion
Retirement
Disability

Changes in parenting time:

Custody or visitation modifications
Child primarily living with the other parent
Substantially increased or decreased parenting time

Changes in child's needs:

Increased medical expenses
Special education needs
Age-related changes (e.g., starting college, though support typically ends at 18 or 19)

Changes in expenses:

Significant increase in health insurance costs
Substantial childcare expense changes
Loss of employment-related childcare need

Changes in family composition:

Birth of additional children to either parent
Other dependents in the household

The Modification Process

Option 1: Through DHS (Administrative Process)

Either parent requests a review through Tennessee DHS
DHS conducts a financial review
If a modification is warranted, DHS issues a modified order
Either parent may request a hearing to contest the modification
The administrative law judge issues a final decision

Option 2: Through Court (Judicial Process)

File a Petition to Modify Child Support in the court that issued the original order
Serve the other parent with the petition
Provide current financial documentation
Attend mediation (if required)
Attend the hearing
Receive the modified court order

Required Documentation

When seeking modification, be prepared to provide:

Recent pay stubs (typically 3-6 months)
Tax returns for the past 2-3 years
W-2 forms or 1099 forms
Proof of health insurance costs
Documentation of childcare expenses
Proof of extraordinary medical expenses
Documentation of any income changes (termination letters, new employment contracts, etc.)

Retroactive Modification

Tennessee courts typically limit retroactive modifications to:

The date the petition was filed (not the date circumstances changed)
Exceptions may apply in cases of voluntary unemployment or underemployment

Child Support Enforcement in Tennessee

Tennessee has multiple enforcement mechanisms to ensure child support orders are followed. When a parent fails to pay child support, various enforcement actions can be taken.

Tennessee Department of Human Services (DHS) Enforcement

The Tennessee DHS Child Support Services division provides enforcement assistance including:

Location services: Finding non-custodial parents
Paternity establishment: Legal determination of fatherhood
Order establishment: Creating formal support orders
Enforcement services: Collecting past-due support
Review and adjustment: Modifying orders when appropriate

Income Withholding (Wage Garnishment)

Income withholding is the most common enforcement method in Tennessee. See the detailed Income Withholding section below for complete information.

License Suspension

Tennessee law allows for the suspension of various licenses for non-payment of child support:

Driver's License Suspension:

Driver's licenses may be suspended for past-due child support
A 60-day notice must be provided before suspension
Suspension can be avoided by:
Paying the arrears in full
Entering into a payment plan with DHS
Requesting a hearing to contest the suspension

Professional License Suspension:

Professional licenses (medical, legal, contracting, etc.) may be suspended
Occupational licenses (hunting, fishing, etc.) may be suspended
Same 60-day notice requirement applies

Tax Refund Interception

Tennessee and federal tax refunds may be intercepted for past-due child support:

Federal tax refund interception through the Federal Tax Refund Offset Program
State tax refund interception through Tennessee DHS
Past-due support must meet minimum thresholds (typically $150 for federal, $500 for state)

Financial Institution Data Match (FIDM)

Tennessee participates in the Financial Institution Data Match program:

Banks are required to identify accounts belonging to child support obligors
Funds may be seized from bank accounts to satisfy arrears
Notice is typically provided before seizure

Credit Bureau Reporting

Past-due child support may be reported to credit bureaus:

Negative impact on credit scores
Can affect ability to obtain loans, credit cards, housing
Reported arrears must meet minimum thresholds

Liens and Property Seizures

Tennessee can place liens on property for unpaid child support:

Real estate liens: Prevent sale or refinancing until arrears are paid
Personal property liens: May affect vehicles and other valuable property
Property seizure: In extreme cases, property may be seized and sold

Contempt of Court Proceedings

Willful failure to pay court-ordered child support may result in contempt of court:

Civil Contempt:

Purpose is to compel payment
May result in jail time until payment is made (coercive incarceration)
"Purge amount" (payment required for release) is set by the court

Criminal Contempt:

Purpose is to punish willful violations
Less common than civil contempt
May result in fines and jail time as punishment

Passport Denial or Revocation

The U.S. Department of State may deny or revoke passports for individuals with:

Child support arrears exceeding $2,500
Certified past-due support reported by state agencies

Income Withholding in Tennessee

Income withholding, also known as wage garnishment, is the primary method for collecting and enforcing child support in Tennessee.

How Income Withholding Works

When an income withholding order is issued:

The order is sent to the obligor's employer
The employer is legally required to withhold the specified amount from each paycheck
The withheld amount is sent to the Tennessee State Disbursement Unit (SDU)
The SDU processes the payment and distributes it to the custodial parent
Payments are typically recorded in the Tennessee child support payment system

Types of Income Subject to Withholding

Tennessee law defines income broadly for withholding purposes:

Traditional Employment Income:

Wages and salaries
Commissions
Bonuses
Overtime pay
Tips (when reported)

Non-Traditional Income:

Self-employment income (through alternative arrangements)
Unemployment benefits
Workers' compensation benefits
Disability benefits
Pension and retirement payments
Annuity payments
Social Security benefits (except SSI)
Veterans' benefits

Withholding Limits

Under federal law (Consumer Credit Protection Act):

Maximum withholding: Up to 50% of disposable earnings for child support
Higher percentage (up to 60%) if the obligor is not supporting another family
Additional 5% may be withheld for arrears over 12 weeks

New Hire Reporting

Tennessee employers must:

Report all newly hired employees to the state within 20 days
Report independent contractors in some cases
This information is matched against child support orders
Income withholding orders are automatically issued when matches are found

Employer Responsibilities and Penalties

Employers who fail to comply with income withholding orders may face:

Financial penalties
Liability for support amounts that should have been withheld
Legal action by the state

Employers are protected from liability when they properly comply with income withholding orders.

Immediate Income Withholding

Tennessee law requires immediate income withholding in most cases:

New child support orders typically include immediate withholding
Exceptions are rare and require specific findings by the court
Even when arrearages are not owed, withholding may begin immediately

Child Support Arrears and Interest

When child support payments are not made in full and on time, arrears (past-due support) accumulate. Understanding how arrears work is crucial for both parents.

What Are Arrears?

Arrears are unpaid child support obligations that have accrued under a court order. In Tennessee:

Arrears accumulate from the date payment was due
Payment is typically due monthly or according to the court order
Arrears cannot be reduced or eliminated without court approval
Arrears create a legal debt that survives the child's majority

Interest on Arrears

Tennessee law allows for the accrual of interest on past-due child support:

Interest rates are set by statute
Interest compounds on the unpaid balance
Interest continues to accrue until the arrears are paid in full
Interest payments are in addition to the current child support obligation

Accounting for Arrears

Tennessee maintains detailed records of child support payments:

Payments are applied according to state law and court order
Payments typically apply first to current support, then to arrears
Parents can request payment records and accountings
Disputes about payment records may require court intervention

Reducing or Eliminating Arrears

Arrears generally cannot be reduced or eliminated retroactively, but exceptions exist:

Retroactive Modification:

Generally not permitted (modification applies from filing date)
Exceptions for voluntary unemployment or underemployment
Requires court approval and specific findings

Compromise Agreements:

Parties may agree to compromise arrears in some circumstances
Must be approved by the court or DHS
Court must find the compromise is in the child's best interests

Statute of Limitations:

Arrears generally remain enforceable until paid in full
No statute of limitations on child support arrears in Tennessee
Arrears can be collected even after the child turns 18

Bankruptcy and Child Support Arrears

Child support arrears are not dischargeable in bankruptcy:

Support obligations survive bankruptcy proceedings
Bankruptcy does not stop income withholding or enforcement
Chapter 13 bankruptcy may provide time to catch up on payments

Termination of Child Support

Child support does not continue indefinitely. Understanding when child support ends is important for both parents.

Standard Termination Events

Tennessee child support typically ends when:

Child reaches age 18 OR
Child graduates from high school, whichever is later, but not beyond age 19

Extended Support Exceptions

Child support may continue past age 19 in limited circumstances:

Disability: If the child is physically or mentally disabled and unable to support themselves
Agreement: Parents may agree to extend support (e.g., through college)
Court order: A court may order support beyond age 19 in rare circumstances

Post-Majority Educational Support

While Tennessee law does not generally require parents to pay for college expenses, exceptions exist:

Separation agreements or divorce decrees that specify college support
Mediated agreements that include educational support
Court-ordered support in unusual circumstances

Emancipation

A child may be emancipated before age 18, terminating child support:

Marriage typically emancipates a child
Joining the military may emancipate a child
Court order of emancipation
Financial independence (in rare circumstances)

College Expenses

Tennessee law generally does not require parents to pay college expenses. However:

Parents may voluntarily agree to contribute
Courts may consider college expenses in modification proceedings
Some counties have different practices regarding college support

Health Insurance After Support Ends

Even when child support payments terminate, parents may remain obligated to:

Provide health insurance if available at reasonable cost
Continue health insurance coverage until the child is no longer eligible
This obligation may extend past age 19 under some circumstances

Frequently Asked Questions

How is child support calculated in Tennessee?

Tennessee uses the Income Shares Model for child support calculations. Both parents' incomes are combined, and the Tennessee Child Support Schedule determines the total support obligation based on the combined income and number of children. Each parent pays their proportionate share based on their percentage of the combined income, adjusted for parenting time and additional expenses like health insurance and childcare.

What is the Tennessee child support calculator?

The Tennessee Department of Human Services provides an official child support calculator that automates the Income Shares calculation. This tool considers both parents' incomes, parenting time arrangements, health insurance costs, childcare expenses, and other relevant factors to calculate the appropriate support amount.

At what age does child support end in Tennessee?

Child support in Tennessee typically ends when the child turns 18, or when they graduate from high school, whichever is later, but not beyond age 19. Exceptions exist for disabled children who cannot support themselves, or when parents have agreed to extend support (such as for college expenses).

Can child support be modified in Tennessee?

Yes. Child support can be modified when there has been a substantial and material change in circumstances. Common qualifying changes include significant income changes, changes in parenting time, changes in the child's needs, or changes in expenses like health insurance or childcare. Either parent can request a modification through DHS or by filing a petition in court.

What happens if I don't pay child support in Tennessee?

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

Income withholding (wage garnishment)
Suspension of driver's license and professional licenses
Seizure of tax refunds
Liens on property
Contempt of court proceedings (including possible jail time)
Credit bureau reporting
Passport denial or revocation

Can child support arrears be forgiven in Tennessee?

Generally, no. Child support arrears create a legal debt that cannot be retroactively modified or forgiven except in very limited circumstances. Even if the parties agree to compromise arrears, court approval is required, and the court must find the compromise is in the child's best interests.

Does overtime income count toward child support in Tennessee?

It depends on whether the overtime is consistent. Regular, predictable overtime is typically included as income. Occasional or voluntary overtime may be treated differently—courts may average it over time or exclude it if it's truly discretionary. Each case is fact-specific.

How is self-employment income calculated for Tennessee child support?

For self-employed parents, Tennessee typically uses gross business income minus reasonable business expenses. Courts may add back personal expenses disguised as business expenses, depreciation, and other deductions that don't reflect actual economic resources. Business income may be averaged over multiple years to account for fluctuations.

What if I lose my job and can't pay child support?

If you lose your job, you should immediately file a petition to modify child support. The modification will typically take effect from the filing date, not the date of job loss. You remain responsible for the ordered amount until a modification is granted. Document your job search efforts and any unemployment benefits received.

Not necessarily, but it depends on income disparities. In 50/50 parenting arrangements, Tennessee uses the shared parenting worksheet, which calculates each parent's obligation based on income and provides a credit for parenting time. If incomes are equal, support may be minimal. If one parent earns significantly more, they may still owe support even with equal parenting time.

Can I stop paying child support if my ex won't let me see the kids?

No. Child support and parenting time are separate legal issues in Tennessee. You must continue paying court-ordered child support regardless of visitation problems. If you're being denied parenting time, the proper remedy is to file a petition for contempt or to modify the parenting plan—not to withhold support.

How is health insurance handled in Tennessee child support?

The parent who provides health insurance for the child typically receives a credit against their child support obligation. The child's portion of the health insurance premium is added to the basic support amount, and the paying parent receives credit for this amount. Uninsured medical expenses over a certain threshold (usually $250/year) are typically prorated between parents based on their income percentages.

What is the minimum child support in Tennessee?

Tennessee does not have a statutory minimum child support amount. However, the Child Support Guidelines produce minimum amounts based on the parents' combined income. Even very low-income parents are expected to pay some amount of child support, unless they are truly destitute.

Does Tennessee child support consider new spouses' income?

Generally, no. A new spouse's income is not typically included in child support calculations. However, new spouses' financial contributions to the household may be considered in certain circumstances, such as when determining whether a parent is voluntarily underemployed or when evaluating the household's overall financial circumstances.

How long does it take to establish child support in Tennessee?

If both parents cooperate and financial information is readily available, child support can often be established within 30-60 days through the Tennessee DHS process. If court action is required, or if there are disputes about income or paternity, the process may take 3-6 months or longer.

Can Tennessee child support be enforced across state lines?

Yes. Tennessee participates in various interstate child support enforcement programs, including the Uniform Interstate Family Support Act (UIFSA). Child support orders can be enforced across state lines through income withholding, tax refund interception, license suspension, and other enforcement mechanisms.
