WA Child Support Schedule 2026: Reading the Economic Table

Disclaimer: This guide explains the 2026 Washington Child Support Schedule for educational purposes. It is not legal advice. Consult a licensed WA family law attorney for advice specific to your case.

Every child support order in Washington State begins with the same document: the Washington State Child Support Schedule (WSCSS) economic table. It is a published table that shows how much Washington believes it costs to raise children at different combined income levels, and it is legally mandated as the starting point for every calculation under RCW 26.19. Understanding how to read it, and what it actually tells you, demystifies a large portion of the child support process.

What Is the WSCSS Economic Table?

The economic table is a grid. The rows represent combined monthly net income levels in $100 increments. The columns represent the number of children, 1, 2, 3, 4, 5, or 6 or more. Each cell in the table contains the Basic Support Obligation (BSO), the total amount Washington estimates it costs to raise that number of children at that combined income level per month.

The table is based on economic research into what intact families actually spend on children at different income levels. The legislature updates it periodically, the 2026 table reflects cost-of-living changes and revised expenditure data, producing an increase of approximately 4.2% across most income brackets from the prior schedule.

The Critical Distinction: BSO vs. Transfer Payment

This is where many people get confused. The number in the economic table, the Basic Support Obligation, is not what either parent pays. It is the total combined obligation before it is split between the parents.

Each parent is responsible for their proportional share of the BSO based on their share of combined income. If Parent A earns 65% of combined income, Parent A is responsible for 65% of the BSO. The transfer payment (what actually changes hands) is the share owed by the parent with fewer residential days.

How to Read the Table Step by Step

1. Calculate both parents' monthly net income after all permitted deductions under RCW 26.19.071
2. Add both net incomes together to get combined monthly net income
3. Find the income row in the table that matches your combined income. Round to the nearest $100 increment
4. Find the column for your number of children
5. The number in that cell is your BSO. The starting point for the calculation
6. Calculate each parent's share by multiplying the BSO by each parent's income percentage
7. Add extraordinary expenses, childcare, health insurance, uninsured medical, split proportionally on top

What Happens Above $50,000 Combined Income?

The 2026 economic table covers combined monthly net income up to $50,000. Above that threshold, the table ends and courts use judicial discretion. They apply the table's top-tier amount as a starting point and may add a percentage of income above the cap based on the child's actual needs, the family's established lifestyle, and the parents' specific financial circumstances. High-income cases above $50,000 combined typically involve attorney representation and more detailed litigation.

What Changed from the Prior Schedule

The 2026 table increased by approximately 4.2% across most combined income brackets compared to the prior schedule. This means if your order was set under an earlier schedule and your incomes have not changed, recalculating under the 2026 table will likely produce a higher BSO. If 3 years have passed since your order was set, you may have grounds to request modification using the updated 2026 table, use the Modification Calculator to check your numbers.

Why You Should Use a Calculator Rather Than the Raw Table

The published table uses $100 income increments, but your actual combined income almost certainly falls between two rows. Courts interpolate between rows to find the precise BSO for your exact income. A calculation that is easy to get wrong manually. Our calculator handles this interpolation automatically along with the proportional share split and extraordinary expense addition, giving you the complete picture in seconds rather than requiring manual table lookup and arithmetic.

Bottom Line

The 2026 WSCSS economic table is the foundation of every Washington child support order, but it is the starting point, not the final number. The BSO from the table gets split by income share, then adjusted for extraordinary expenses, the Self-Support Reserve, and the 45% cap before producing the actual transfer payment. Use our calculator to handle all of this automatically with your specific numbers.
