Is your child getting the financial support they deserve? Washington’s child support system might seem complex, but we’re here to break it down into clear, actionable information you can use today.
As parents, we all want what’s best for our children. When relationships end, ensuring your child’s financial well-being becomes even more crucial. Whether you’re paying or receiving child support, understanding Washington State’s guidelines helps you make informed decisions and advocate for your child’s needs.
What is Child Support in Washington State?
Child support is a financial contribution that helps cover a child’s basic needs including housing, food, clothing, education, and healthcare. In Washington State, both parents are legally responsible for financially supporting their children, regardless of their relationship status.
The Washington State Legislature established a child support schedule to ensure children receive consistent, fair support based on their parents’ financial situations. This schedule helps courts determine appropriate support amounts in divorce cases, parentage actions, and other family law matters.
How Washington Calculates Child Support
Washington uses what’s called the “Income Shares Model” to calculate child support. This approach is based on the principle that children should receive the same proportion of parental income they would have received if their parents lived together.
The Basic Calculation Process
- Determine each parent’s net income
- Calculate the combined monthly net income
- Find the basic support obligation from the economic table
- Allocate the support obligation between parents
- Calculate additional expenses like healthcare and childcare
- Apply any appropriate adjustments or deviations
Let’s break down each step:
1. Determining Net Income
The court first determines each parent’s monthly gross income from all sources, including:
- Wages and salary
- Bonuses and commissions
- Interest and dividend income
- Business income
- Unemployment benefits
- Workers’ compensation
- Social Security benefits
- Spousal maintenance (alimony)
From this gross income, certain deductions are allowed:
- Federal income taxes
- State income taxes (if applicable)
- FICA (Social Security and Medicare taxes)
- Mandatory pension contributions
- Mandatory union dues
- State industrial insurance premiums
The result is the parent’s net income for child support purposes.
2. The Economic Table
After determining the parents’ combined net monthly income, the court refers to the Washington State Child Support Schedule Economic Table (RCW 26.19.020) to find the basic support obligation based on the number and ages of children.
The Washington economic table is presumptive for combined monthly net incomes up to $12,000. For incomes exceeding this amount, the court may use its discretion to set higher support amounts with proper written findings.
3. Proportional Allocation
Each parent’s share of the basic support obligation is calculated based on their proportional share of the combined net income. For example, if one parent earns 60% of the combined income, they’re responsible for 60% of the basic support obligation.
4. Additional Expenses
Beyond the basic support obligation, parents share other expenses proportionally:
Healthcare Costs: Health insurance premiums and uninsured medical expenses are typically allocated between parents in proportion to their incomes. Health-related expenses include medical, dental, orthodontic, vision, pharmaceutical, and other healthcare costs.
Childcare Expenses: Work-related childcare costs are shared proportionally between parents.
Educational Expenses: Costs for educational needs, including special private education or tutoring when appropriate.
Long-Distance Transportation: Expenses for transportation between parents’ homes for visitation.
Extracurricular Activities: Costs for the child’s activities may be shared.
Support Limits and Special Situations
Low-Income Provisions
Washington law provides some protection for low-income parents. If a parent’s net income is below 125% of the federal poverty level, the court generally won’t order them to pay more than what they can reasonably afford while still meeting their own basic needs.
The minimum support obligation is typically $50 per month per child unless the court finds even this amount would be unjust.
Maximum Support
Child support typically won’t exceed 45% of a parent’s net income unless there’s good reason, such as:
- The child has special needs
- The family is particularly large
- Other compelling circumstances exist
Imputed Income
If a parent is voluntarily unemployed or underemployed, the court may “impute” income based on what they could earn if fully employed. This prevents parents from deliberately reducing income to lower support obligations.
The court considers factors like:
- Work history
- Education and skills
- Available employment opportunities
- Health and disabilities
- Age
Residential Schedule Credit
When a child spends significant time with the paying parent (typically more than 90 overnights per year), the court may consider a deviation from the standard calculation to account for increased expenses during this time.
Unlike many states, Washington doesn’t have a formal formula for shared custody adjustments in its standard calculation. Instead, parents with substantial residential time must specifically request a deviation.
Modifying Child Support
Child support orders aren’t set in stone. They can be modified when circumstances change significantly:
When You Can Request Modification
- Substantial Change in Circumstances: A significant change in finances, healthcare needs, residential schedule, or other factors that wasn’t anticipated when the order was established.
- Periodic Adjustment: If at least two years have passed since the order was established or last modified, it can be adjusted based on changes in parents’ incomes or in the state’s guidelines.
Modification Process Options
- Through the Division of Child Support (DCS): If you have an open case with DCS, you can request a review. If they find a significant difference (generally 15% or more) between your current order and what would be ordered under current circumstances, they may initiate modification proceedings.
- Court Petition: You can file a Petition to Modify Child Support directly with the superior court in your county.
- Motion for Adjustment: In some cases, a simpler Motion for Adjustment can be used, which typically requires less paperwork and a shorter process.
Support Enforcement
Washington takes child support obligations seriously. When parents fall behind, enforcement measures include:
- Income withholding (wage garnishment)
- Interception of tax refunds
- Suspension of driver’s, recreational, and professional licenses
- Liens against property
- Seizure of bank accounts
- Reporting to credit bureaus
- Passport denial
- Contempt of court proceedings (which may lead to fines or jail time)
The Division of Child Support (DCS) handles enforcement actions for both administrative and court-ordered support obligations.
Common Questions About Washington Child Support
How long does child support continue?
In Washington, child support typically continues until the child turns 18 or graduates from high school, whichever occurs later (but generally not beyond age 19). In some cases, support for post-secondary education may be ordered.
Can support cover college expenses?
Yes, but it’s not automatic. Courts may order post-secondary educational support when appropriate, considering factors like the child’s aptitude for higher education, parents’ expectations, and financial resources.
Does remarriage affect child support?
A parent’s remarriage alone doesn’t justify modifying child support. However, if remarriage significantly changes economic circumstances, it might be considered along with other factors.
What if the paying parent moves out of state?
Washington can enforce support orders across state lines through the Uniform Interstate Family Support Act (UIFSA). DCS works with other states to locate parents and enforce orders.
Can parents agree to a different amount than the guidelines suggest?
Yes, parents can agree to deviate from the standard calculation if the court finds it’s in the child’s best interest and adequately provides for their needs.
Does visitation affect child support?
Child support and visitation are legally separate issues. A parent cannot withhold visitation because of unpaid support, nor stop paying support because visitation is denied. Each requires its own legal remedies.

Frequently Asked Questions
How do I apply for child support services in Washington?
You can apply for services through the Division of Child Support (DCS) by completing an application online or submitting a paper form. Even if you weren’t married to your child’s other parent, DCS can help establish parentage and obtain a support order.
How is child support paid in Washington?
Most support payments are processed through the Washington State Support Registry. Common payment methods include:
- Income withholding (directly from wages)
- Electronic payments through the state’s payment portal
- Automatic bank withdrawals
- Mail-in payments
- Mobile payment apps
What if I can’t afford my child support payments?
If your financial situation changes, don’t wait until you fall behind. Contact DCS or consider filing for a modification as soon as possible. You may qualify for a reduction based on your current circumstances.
How does joint custody affect child support in Washington?
Washington doesn’t automatically reduce support for 50/50 custody arrangements. However, parents with significant residential time can request a deviation from the standard calculation, which the court may grant if it’s in the child’s best interest.
Can child support include childcare costs?
Yes, work-related childcare expenses are typically shared between parents in proportion to their incomes and are in addition to the basic support obligation.
Will DCS help enforce my court order?
Yes, DCS provides enforcement services for all support orders. Their tools include wage garnishment, license suspension, tax refund interception, and more.
Can I modify child support without going to court?
If you have an administrative order through DCS, you can often modify it without court involvement. For court orders, DCS can sometimes help with the modification process, or you can file the necessary paperwork with the court yourself.
