The Presumptive Tables and the Self-Support Reserve in Wyoming

By the FigureMyTax Editorial Team · How we calculate

Wyoming’s presumptive tables, effective July 1, 2023, give a joint obligation as base support plus a marginal percentage of combined net income from $1,000, divided by net income, and the support cannot exceed the obligor’s net income above the poverty-line self-support reserve.

The tables

The statute gives a table for one, two, three, four and five or more children (Wyo. Stat. 20-2-304(a); the 2023 amendment is House Bill 12). Each line lists combined net monthly income of both parents, the percentage of income allocated and a base support plus a marginal percentage on income over the line: for one child, $230 + 23.0% over $1,000, $461 + 23.0% over $2,000, $737 + 20.1% over $3,200, $898 + 13.4% over $4,000, $965 + 11.8% over $4,500, $1,379 + 11.1% over $8,000 and $2,157 + 10.3% over $15,000.

Other family sizes

For two children the lines run from $351 + 35.1% over $1,000 to $3,171 + 15.3% over $15,000; for three, $424 + 42.4% to $3,698 + 18.1%; for four, $474 + 47.4% to $4,130 + 20.2%; and for five or more, $521 + 52.1% to $4,543 + 22.2%. At combined net income of $5,000 the joint obligation is $1,024 for one child and $1,539 for two; at $8,000 and two children it is $2,048; at $30,000 and two children it is $5,466.

Dividing the obligation

The joint obligation is divided between the parents in proportion to their net incomes and the noncustodial parent’s share is paid to the custodial parent through the clerk. With net incomes of $3,000 and $5,000, the noncustodial parent pays 62.5% of $2,048, or $1,280.

The self-support reserve

If the difference between the obligor’s net income and the self-support reserve is less than the support from the tables, the support is that difference. The reserve is the current federal poverty line for one person, which for 2026 is $15,960 a year, or $1,330 a month (Federal Register). A noncustodial parent with $1,500 of net income owes $170 rather than $485; with $1,800, $470 rather than $564.

Below $1,000

The statute’s tables begin at $1,000 of combined net monthly income. For lower incomes this calculator applies the percentage on the first line, and the self-support reserve still limits the result; a combined net income of $500 with one parent at $200 gives $0 because that parent has nothing above the reserve.

A presumptive amount

The statute calls the tables presumptive child support; Wyoming courts may deviate on their findings, which this calculator does not model.
