What Is the Minimum Child Support Payment in Washington?

If money is tight, you may be wondering whether a court can order child support you genuinely cannot afford. Washington law sets a floor on support, but it also protects a paying parent from being pushed below a basic standard of living. This topic is part of Washington divorce, custody, and support law.

The $50 Per Child Presumptive Minimum

Washington calculates child support using a statewide economic table that matches a support amount to the parents' combined monthly net income and the number of children. Built into that table is a floor: minimum support may not be less than $50 per child per month, except in the limited circumstances the statute allows. That rule appears directly in the economic table set out in RCW 26.19.020, which as amended effective January 1, 2026, carries the same $50 per child per month language it has long included.

So if you have two children, the starting point for a presumptive minimum is $100 per month, and for three children it is $150 per month. The word "presumptive" matters. It means the court starts from that number, but the number can move up or down when the facts justify it. The $50 figure is not a target most orders land on. It is the low end of the scale, reserved for parents whose income sits at the bottom of the table.

What Happens When Income Falls Below the Table

The economic table does not begin at zero. As amended effective January 1, 2026, the table's lowest income tier starts at a combined monthly net income of $2,200. For income below that figure, RCW 26.19.020 provides that the support obligation is based on the resources and living expenses of each household rather than a fixed table amount. In plain terms, when a parent earns very little, the court looks at what each household actually has and what it actually needs instead of simply reading a number off a chart.

Even in those low-income situations, the $50 per child per month presumptive minimum still applies, unless the paying parent shows that it would be unjust to order even that much in the particular case. This is where the companion statute comes in.

The Self-Support Reserve: Protecting a Paying Parent's Basic Needs

Washington does not want a support order to leave a parent unable to survive. To that end, RCW 26.19.065 sets standards for the lower and upper limits on support. As amended effective January 1, 2026, it establishes a self-support reserve set at 180 percent of the federal poverty level for a one-person family. The basic support obligation of the parent making the transfer payment, not counting health care, day care, and special child-rearing expenses, generally may not reduce that parent's net income below the self-support reserve.

There is an important exception written into the same section. The self-support reserve does not shield a parent from the $50 per child per month presumptive minimum. In other words, the reserve can lower a support amount, but it does not erase the floor. The statute also allows a court to depart from the reserve when applying it would be unjust after weighing the best interests of the child and the circumstances of each parent, including whether the custodial household would be left without enough to meet the child's basic needs.

RCW 26.19.065 also addresses parents whose monthly net income falls below 180 percent of the federal poverty guideline for a one-person family. In those cases, a support order of not less than $50 per child per month is entered unless the parent who owes support establishes that it would be unjust to do so in that particular case. The court weighs the child's best interests and each parent's circumstances, including comparative hardship, assets, liabilities, and earning capacity.

Why the Minimum Rarely Tells the Whole Story

Because these rules interact, two parents with similar incomes can end up with different orders. One parent may qualify for the presumptive minimum while another, with slightly higher income or different household expenses, lands above it. The court is not simply plugging numbers into a formula. It is applying the table, the self-support reserve, and the fairness standards together, then documenting the result.

It is also worth remembering that the $50 minimum is a presumption, not a guarantee. A parent who wants to pay less than $50 per child per month carries the burden of convincing the court that even that amount would be unjust given the specific facts. Courts do not lower support below the presumptive minimum casually.

What This Means for Snohomish County Families

For parents filing in Snohomish County Superior Court, these rules are applied the same way they are statewide, but local circumstances shape the outcome. Housing costs in Everett, Marysville, Lynnwood, and the surrounding communities affect what each household reasonably needs to meet a child's basic living expenses, and those real-world numbers feed directly into the resources-and-living-expenses analysis the statute calls for when income is low. A support figure that looks right on a worksheet still has to make sense against the cost of raising a child here.

If you are worried that a proposed support amount is either too high to survive or too low to meet your child's needs, the details of your income, your household, and the other parent's situation all matter. A careful review of the worksheet, the self-support reserve calculation, and any grounds for departing from the presumptive minimum can make a real difference in the final order.
