Kansas Child Support Calculator And Guidelines Explained

Child support in Kansas follows a structured **income shares model** designed to approximate the financial support children would receive if parents remained together. Courts use official **Child Support Guidelines** to calculate obligations based on both parents’ incomes, number of children, and their ages. This ensures fairness while prioritizing children’s needs.

The process involves completing a **Domestic Relations Affidavit** and **Child Support Worksheet**, which detail incomes, expenses, and adjustments. Judges rarely deviate from worksheet results unless justified in the child’s best interest.

The Income Shares Model

Kansas employs the **income shares model**, where support reflects the combined parental income proportional to each parent’s contribution. Basic child support obligations are derived from schedules in the guidelines, categorized by children’s ages: 0-5, 6-11, and 12-18 years.

For combined monthly incomes exceeding schedule maximums (typically around $16,000), an **extended formula** applies: Combined monthly income raised to the power of 0.61209, multiplied by 5.749332, then adjusted for age categories. For example, for $16,000 income and one child aged 12-18: $16,000^0.61209 × 5.749332 ≈ $2,152 monthly obligation.

• One child (12-18): Base $2,152; adjust down 6% for 6-11 ($2,023), 16% for 0-5 ($1,807).
• Multiple children: Sum individual obligations from age-specific calculations.

Each parent’s share is their proportion of combined income applied to the total obligation.

Child Support Schedules

Guidelines include **Child Support Schedules** (tables) listing monthly obligations by combined income and child count/age. For one child:

Similar tables exist for 2+ children. Parents lookup values, sum for multiple ages, and proceed to proportionate shares.

Determining Parental Income

**Gross income** includes wages, bonuses, self-employment earnings, investments, and imputed income for voluntary unemployment/underemployment. Courts impute based on work history, skills, job market, health, and age.

**Deductions** yield monthly child support income: federal/state taxes, FICA, mandatory retirement, health insurance, prior child support. Self-employed deduct business expenses.

• Verify via pay stubs, tax returns; non-disclosure risks court-imputed income.
• Imputed income example: Unemployed skilled worker imputed at median wage for their field.

Basic Child Support Obligation

After income determination, locate **basic obligation** from schedules or extended formula on Worksheet Line D.3. For mixed ages, sum age-specific amounts (e.g., 4-year-old $552 + 7-year-old $618 = $1,170).

Adjustments to the Obligation

Parenting Time Adjustment

Non-primary parent receives credits for substantial parenting time:

• 35-39%: 10% reduction
• 40-44%: 20% reduction
• 45-49%: 30% reduction
• 50%+ shared: Special equal/shared expense formulas

Apply after basic obligation (Line D.5), then recalculate proportionate shares (Line D.6).

Child Care and Health Insurance

**Child care costs** added after federal tax credit adjustment (max 34% credit, capped per table). Example: $525/month × 34% = $179 (capped $85), net $440 added.

**Health insurance** premiums for children added to obligation, split proportionately.

Multiple Family Adjustments

Adjust for other children: Sequential (prior-born) or simultaneous (same-time born). Reduces current obligation via specified percentages.

Ability to Pay Calculation

For low-income parents, subtract federal poverty guideline (one-person household, e.g., ~$1,255/month in recent years) from support income. If result < obligation, court sets amount in child's best interest.

Formula: Child support income (Line D.1) – poverty level = ability to pay (Line F.5a). Cap support at this if lower.

Final Child Support Order

Worksheet culminates in:

1. Basic obligation (F.1)
2. Adjustments (F.2: +child care/insurance, -credits)
3. Ability to pay cap (F.5)
4. Enforcement fee (e.g., 4% of obligation, split)

Non-custodial pays custodial their share. Agreements deviating from worksheet require justification.

Deviations from Guidelines

Courts deviate only for extraordinary reasons, documented in findings: child’s extraordinary needs, parental resources, standard of living.

Child Support Calculators

Online tools like eFamilyTools, Bradley Software, or CustodyXChange estimate obligations. Official: Kansas Courts worksheets. Always verify with worksheet for court.

Modifying Child Support

Modify for 10%+ change in circumstances (income, custody) lasting 12+ months. File motion; use updated worksheet.

Frequently Asked Questions

What is the Kansas child support formula?

Kansas uses income shares: combined income → schedule/extended formula → proportionate shares with adjustments.

How does parenting time affect child support?

Credits: 10-30% for 35-49% time; shared formulas for 50%+.

Can child support be imputed?

Yes, for voluntary unemployment based on earning capacity.

What if income exceeds schedules?

Use extended exponential formula; check ‘extended formula used’ box.

How to calculate enforcement fees?

Typically 4% of obligation, split equally (e.g., $2,000 × 4% × 0.5 = $40/parent).
