Wyoming Child Support Guidelines in 2026
Looking for Wyoming child support guidelines for 2026? The presumptive tables are in W.S. 20-2-304(a). The old subsection (b) was repealed by Laws 2018, ch. 42, and the net income definition was last changed by Laws 2019, ch. 186. We found no newer change to the tables for 2026.
The self-support reserve follows the federal poverty line for one person, which changes every year: $15,960 a year ($1,330 a month) in 2026 (HHS poverty guidelines).
The Wyoming Presumptive Child Support Tables
Each row gives the total obligation as a base amount plus a percentage of combined net income above that row:
| Combined net monthly income | 1 child | 2 children | 3 children |
|---|
| $1,000 | $230 + 23.0% | $351 + 35.1% | $424 + 42.4% |
| $2,000 | $461 + 23.0% | $702 + 33.9% | $848 + 40.4% |
| $3,200 | $737 + 20.1% | $1,108 + 31.0% | $1,334 + 36.5% |
| $4,000 | $898 + 13.4% | $1,356 + 19.6% | $1,626 + 22.8% |
| $4,500 | $965 + 11.8% | $1,454 + 17.0% | $1,740 + 19.2% |
| $8,000 | $1,379 + 11.1% | $2,048 + 16.0% | $2,412 + 18.4% |
| $15,000 | $2,157 + 10.3% | $3,171 + 15.3% | $3,698 + 18.1% |
Wyoming has tables for one, two, three, four and five or more children. Above $15,000 the last percentage applies to all income over $15,000. The tables start at $1,000; below that this calculator applies the $1,000 row percentage.
Self-Support Reserve
Under W.S. 20-2-304(f), if the paying parent's net income minus the self-support reserve is less than the table amount, support is set at that difference. The self-support reserve is the current federal poverty line for one person: $1,330 a month in 2026. The statute sets no fixed minimum order.
Shared Responsibility and Split Custody
When each parent keeps the children overnight more than 25% of the year and both contribute substantially to their expenses (W.S. 20-2-304(c)):
- Multiply the total obligation by 150%.
- Split it between the parents by net income.
- Multiply each parent's share by the percentage of time the children spend with the other parent.
- The parent owing more pays the difference.
When each parent has physical custody of at least one child, the two obligations are offset (split custody, 20-2-304(d)).
Wyoming Child Support Examples
In each example Parent B has the children most of the time. Amounts are monthly and come from this calculator.
Example 1: One child
A earns $5,000 and B earns $3,000 gross. Net incomes are $4,199.17 and $2,592.17 ($6,791.34 combined). The table gives $965 + 11.8% over $4,500 = $1,235.38, and A's 61.8% share is $763.85 a month.
Example 2: Two children, A pays health coverage
A earns $6,000 and pays $200 for the children's coverage; B earns $4,000. Combined net income is $8,152.50, the total is $2,072.40, and A pays 58.3%: $1,209.21 a month.
Example 3: Equal time
A earns $7,000 and B earns $5,000, two children. The $2,345.52 total x 150% is $3,518.28. A's half-time part is $1,009.92 and B's is $749.22, so A pays $260.70 a month.
Example 4: Self-support reserve
A earns $1,800 (net $1,616.47) and B earns $5,000, one child. A's share is $311.38, but only $286.47 is above the $1,330 reserve: $286.47 a month.

Frequently Asked Questions About Wyoming Child Support
Is this the official Wyoming child support calculator?
No. ChildSupportCalculator.xyz is an independent tool and is not affiliated with the State of Wyoming, its courts or the Department of Family Services. It applies W.S. 20-2-304. A court sets the actual amount.
Does Wyoming use gross or net income for child support?
Net income. Each parent's income is reduced by income taxes, Social Security, children's health coverage and certain other payments, and the two net incomes are added.
How is child support calculated in Wyoming?
Find the total obligation in the table for combined net income (a base amount plus a percentage of income above the row), then multiply by the paying parent's share of combined net income.
What is the minimum child support in Wyoming?
The statute sets no fixed minimum. Support may be reduced so the paying parent keeps the self-support reserve, the federal poverty line for one person ($1,330 a month in 2026).
How does 50/50 custody work for child support in Wyoming?
When each parent has the children overnight more than 25% of the year, the total obligation is multiplied by 150%, split by income, multiplied by the time with the other parent, and the parent owing more pays the difference.
Is child care included in Wyoming child support?
Not in the tables. Necessary child day care is a reason the court may deviate from the presumptive amount.
Is there an income cap for child support in Wyoming?
No. Above $15,000 of combined net monthly income, the last percentage in the table applies to all income over $15,000.
Does the Wyoming calculator need my personal details or a login?
No. This site needs no login and does not store your numbers.
