What is the minimum child support in Tennessee, and are you required to pay even if your income is limited? If you’re going through separation or divorce, child support is likely one of your main concerns.
No matter if you’ll pay or depend on support to care for your child, understanding Tennessee’s calculation method can greatly affect your financial future.
Tennessee uses an income-based formula. This ensures that children receive steady financial support from both parents, regardless of the custody arrangement. But trying to navigate legal guidelines on your own can be overwhelming.
This article explains each part of the Tennessee child support process- from how child support works in the state and what the minimum payment is, to the step-by-step calculation of payments and what to expect if challenges arise. As you read, you’ll find clear, plain-English guidance to navigate Tennessee’s child support system.
What Is Child Support And Who Is Required To Pay It In Tennessee?
Child support is a court-ordered financial obligation that ensures both parents contribute to their child’s basic living expenses- things like food, housing, clothing, education, and healthcare.
In Tennessee, the parent who spends less time with the child- the Alternative Residential Parent (ARP)- usually pays child support to the parent with primary custody, the Primary Residential Parent (PRP). Both parents are legally responsible for financially supporting their child.
The Tennessee Department of Human Services (DHS) enforces child support statewide. They also ensure compliance with court orders. Even if parents reach a private agreement, the court must approve any arrangement to make it enforceable.

What Is The Minimum Child Support In Tennessee?
Tennessee does not leave child support amounts to guesswork. The state sets a minimum order of $100 per month, even for parents with very low income. This ‘floor’ ensures a financial contribution from every parent, regardless of employment status. The ‘floor’ is the lowest legal amount ordered by the court.
Courts may calculate support based on a parent’s earning capacity rather than current income, even if the parent is unemployed or between jobs.
Ignoring a child support order leads to accumulating debt. Tennessee enforces payment with wage garnishment, license suspension, or jail time.

What Is The New Child Support Law In Tennessee?
Tennessee updates its child support guidelines to reflect economic changes and ensure fairness. The most recent updates took effect on October 1, 2021.
According to the Tennessee Department of Human Services, these changes may impact both new child support orders and modifications to existing ones. If you established your order several years ago, it may no longer reflect current guidelines — a valid basis for requesting a modification.
Parents should review the Tennessee Child Support Guidelines PDF directly from the DHS website to stay current on any legislative changes affecting their case.
How Does Tennessee Calculate Child Support Payments?
Tennessee uses the Income Shares Model to calculate child support. This approach considers both parents’ incomes. Its goal is to provide the child with the same support they would receive if the family were to stay together.
Here’s how the calculation works:
Step 1. Determining Each Parent’s Gross Monthly Income
Gross income includes wages, salaries, self-employment income, rental income, bonuses, commissions, and other regular sources of income. Tennessee courts consider your full financial picture, not just a W-2.
Step 2. Calculating The Combined Adjusted Gross Income
Add both parents’ gross incomes together. This gives the combined adjusted gross income (AGI), which determines the base support amount on the BCSO schedule.
Step 3. Applying The Basic Child Support Obligation Table
Find the BCSO table in the TN child support worksheet instructions. This table assigns a base dollar amount based on income and the number of children. For example, one child has a different support amount than two or three.
Step 4. Calculating Each Parent’s Proportional Share
Each parent’s share is based on their percent of the combined income. For example, if one parent earns 60% of the income, they cover 60% of the support.
Step 5. Adjusting For Parenting Time
The time each parent spends with the child affects the amount of support. More parenting time usually lowers payments, since that parent covers day-to-day costs during their time with the child.
Parents can use a calculator for an estimate, but the state’s worksheet is the official calculation tool.
What Additional Expenses Are Factored Into Tennessee Child Support Orders?
Base child support does not cover all expenses. Tennessee courts also order parents to split extra costs proportionally.
- Health insurance premiums– The cost of covering the child on a parent’s health plan is factored into the final order.
- Work-related childcare costs– Daycare or after-school care required because a parent is working is included.
- Extraordinary expenses: These include special education needs, ongoing medical treatment, or other unusual costs related to the child’s well-being.
- Other children– Other in-home children are taken into consideration, as well as other children for whom the paying parent is paying support.
These extra expenses are not optional. Courts include them to cover the child’s full needs, not just basic living costs.

How Much Is Child Support In Tennessee For One Child, Two Children, Or Three Children?
The amount depends on both parents’ combined income and the amount of parenting time. Here’s how the numbers change as you add more children.
For one child, a parent earning $5,000/month and the other earning $4,000/month might see a base obligation of $200-$700/month, depending on parenting time. The exact amount depends largely on your income and custody setup.
For two children, the BCSO table assigns a higher base amount- typically 35–45% more than the single-child obligation for comparable income levels. Parents asking how much child support is in TN for 2 kids should factor in that health insurance and childcare costs will increase proportionally.
For three children, the obligation increases again. How much child support in TN for 3 kids depends on the same income-based formula, but the BCSO percentage increases with each additional child, reflecting the higher cost of raising a larger family.
Use the state’s official simple child support calculator to run a preliminary estimate, but always verify with an attorney before relying on those figures in court.
Can Tennessee Child Support Orders Be Modified Or Deviated From?
Yes, but it is not automatic. Tennessee courts can change the guidelines or an existing order if there’s a legal reason.
Valid Grounds For Deviation
Courts may allow deviation when the standard calculation produces an unjust result. Common reasons include a child’s extraordinary medical needs, a parent’s significant financial hardship, or a mutually agreed-upon arrangement that continues to serve the child’s best interests.
What Qualifies As A Substantial Change In Circumstances
To request a modification, a parent must show a substantial change since the last order, meaning at least a 15% variance on the child support obligation. This includes a major change in income, a change in the child’s needs, or a significant shift in parenting time.
How To Request A Child Support Modification In Tennessee
A parent files a petition (a formal written request) with the court that issued the original order. The court then reviews both parents’ current financial situations and the child’s needs before issuing a new order. Under Tennessee’s child support laws, back child support payments still accumulate as debt, so acting quickly matters. The date that the petition is filed matters.

What Happens If A Parent Fails To Pay Child Support In Tennessee?
Non-payment has serious consequences in Tennessee. The state uses several enforcement tools:
- Wage garnishment– Support is withheld directly from the paying parent’s paycheck.
- License suspension– Both driver’s and professional licenses can be suspended.
- Tax refund interception– State and federal refunds can be seized and applied to the balance owed.
- Contempt of court: A judge can hold a non-paying parent in contempt if the parent has willfully disobeyed a court order. This can result in fines or jail time.
Back child support in Tennessee does not disappear. It accrues interest and follows the obligor until paid in full, even across state lines and after the child turns 18.
How Can A Family Law Attorney Help With Child Support In Tennessee?
Child support cases are rarely straightforward. Self-employed parents with variable income, parents disputing custody arrangements, and those seeking modifications all face unique legal challenges that a generic calculator simply can’t solve.
An experienced family law attorney accurately represents your income, properly credits your parenting time, and argues any deviation requests before the court.
Going into a child support hearing without legal representation is a risk that can cost you significantly more in the long run.

Tennessee courts set a minimum of $100 per month, even for parents with little to no income. Courts may impute income if a parent voluntarily underemploys themselves
2. Whether You Have To Pay Child Support With 50/50 Custody In Tennessee

Parents can agree to a different arrangement, but a judge must approve it. Courts will reject any agreement that doesn’t adequately serve the child’s financial needs.
4. How Long Child Support Lasts In Tennessee
Child support generally ends when the child turns 18 or graduates from high school, whichever comes later. Children with certain disabilities may qualify for extended support.
