When parents separate or divorce in Hawaii, child support becomes a critical financial obligation designed to ensure children receive consistent care and resources from both parents. Understanding how Hawaii calculates child support can help you anticipate what you might owe or receive, prepare for court proceedings, and make informed decisions about your family's financial future.

Hawaii's Child Support Model

Hawaii follows the income shares model for calculating child support, a method used by most U.S. states. Under this approach, both parents' incomes are combined to determine a total child support obligation, which is then divided between parents based on their proportional income shares. The philosophy behind this model is that children should benefit from both parents' income in proportion to how much each parent earns.

Unlike older models that placed the entire support burden on one parent, Hawaii's income shares approach recognizes that both parents have a financial responsibility for their children. This creates a more balanced and equitable system that reflects the actual earning capacity of both parents.

Understanding Combined Parental Income

The foundation of Hawaii's child support calculation is determining the combined parental income. This includes:

  • Wages and salaries from employment
  • Self-employment income
  • Income from investments, rental properties, and dividends
  • Retirement and pension income
  • Social Security benefits
  • Spousal support or maintenance received from others
  • Unemployment insurance benefits
  • Worker's compensation benefits

However, certain income sources are excluded from the calculation, including Supplemental Security Income (SSI), Temporary Assistance for Needy Families (TANF), and food stamps. Additionally, if combined parental income exceeds $10,000 per month, the court has discretion in how to apply the guidelines to income above that threshold.

For example, if one parent earns $60,000 annually and the other earns $40,000 annually, their combined parental income would be $100,000. This combined figure then determines the baseline child support obligation before adjustments.

The Basic Child Support Obligation

Hawaii uses standardized child support tables (schedules) based on combined parental income and the number of children. Once the combined income is calculated, the court references these tables to find the basic child support obligation. The amount increases with each additional child, as the family's total needs grow.

For instance, the basic obligation for one child might be $1,500 monthly at a $100,000 combined income level, while two children might result in a $2,200 obligation for the same combined income. These figures are then allocated between parents based on their proportional income.

Allocating Support Between Parents

After determining the basic obligation, Hawaii divides this amount between parents based on their percentage of combined income. If Parent A earns 60% of the combined income and Parent B earns 40%, then Parent A would be responsible for 60% of the basic obligation, and Parent B would be responsible for 40%.

The parent with primary physical custody typically receives support payments from the other parent. However, in shared custody arrangements, the parent with the higher income obligation pays the difference to the other parent.

Adjustments and Additional Factors

The basic obligation is just the starting point. Hawaii courts consider numerous factors that may adjust support amounts up or down:

  • Childcare expenses: Costs for daycare or after-school care necessary for a parent to work
  • Health insurance: Premiums for children's medical, dental, and vision insurance
  • Educational expenses: Private school tuition or special educational needs
  • Custody arrangement: Whether custody is shared equally, joint, or primarily with one parent
  • Standard of living: The lifestyle the child would have enjoyed if parents remained together
  • Financial resources: Each parent's assets and financial situation
  • Child's special needs: Medical conditions or disabilities requiring additional care
  • Tax benefits: How child tax credits and dependency exemptions are allocated

Courts have discretion to adjust the guideline amount if they find the calculation would be unjust or inappropriate under specific circumstances. This flexibility ensures that support orders reflect each family's unique situation.

Self-Employment and Variable Income

Calculating support for self-employed individuals or those with highly variable income requires special attention. Hawaii courts typically average income over a multi-year period to account for business fluctuations. Documentation such as tax returns, profit and loss statements, and business records become critical in these cases.

Parents cannot artificially reduce their income by leaving employment or reducing hours to minimize support obligations. Courts will impute income based on earning potential and work history if they believe someone is intentionally underemployed.

The Importance of Accurate Financial Disclosure

Both parents are required to provide complete and accurate financial disclosure through Affidavits of Financial Status (Form 1). Misrepresenting or hiding income is illegal and can result in serious consequences, including contempt of court charges. The court relies on honest disclosure to calculate fair support amounts.

Modifying Child Support Orders

Child support orders are not permanent and unchangeable. Significant changes in circumstances—such as job loss, income increase, substantial changes in custody, or the child's needs—may warrant modification. Either parent can request a review, and Hawaii law provides specific grounds and procedures for adjusting support amounts.
