What Happens If Child Support Is Not Paid in Washington State?

Disclaimer: This guide explains Washington State enforcement mechanisms for educational purposes. It is not legal advice. If you are facing enforcement actions, consult a licensed Washington family law attorney immediately.

If you're behind on child support in Washington State, whether intentionally or because life threw something unexpected at you, you need to understand exactly what enforcement mechanisms are coming your way and how fast they move. Washington is one of the more aggressive states when it comes to child support enforcement, largely because DSHS's Division of Child Support (DCS) is staffed specifically to pursue non-payers.

The goal of this guide isn't to scare you, it's to help you understand the full picture so you can make the smartest possible decisions. Sometimes that's fighting the order. Sometimes it's getting back on track. Either way, knowledge is your most valuable tool right now.

1. The First Response: Income Withholding Orders (IWOs)

In Washington, virtually every child support order automatically comes with an Income Withholding Order (IWO), also called an earnings withholding order. This is a legal mandate sent directly to your employer requiring them to deduct support payments from your paycheck and send the money to DCS before you ever see it.

Most parents on standard payroll never even miss a payment because the IWO handles it automatically. The problem comes when you change jobs, which is why DCS maintains a New Hire Registry. Every employer in Washington is required to report new hires, and when your name comes up, DCS matches it to any open support orders and sends a new IWO to your new employer, usually within 2 weeks.

If you're self-employed, DCS can issue an IWO to your clients or to financial institutions where you maintain business accounts. The enforcement net is wide, and there are very few employment situations that successfully evade it long-term.

2. The Financial Trap: 12% Annual Interest on Arrears

This is the part that catches parents completely off guard. Washington charges 12% simple annual interest on unpaid child support. Let's put that in real numbers.

Suppose you miss $600/month in payments for 12 months. After one year, you owe $7,200 in principal. But Washington's 12% interest rate means that $7,200 is accruing $864 in interest per year, about $72 per month just in interest. Miss two years of payments, and your principal is $14,400, with growing interest on top of that. After five years, a parent who stopped paying $600/month can easily owe $25,000–$30,000 when interest is calculated.

These debts have no statute of limitations in Washington. DCS can pursue arrears 20 years after your youngest child turns 18. There is no escape route except paying what's owed.

3. License Suspensions: Driver's and Professional

Under Washington law, DCS has the authority to suspend your driver's license if you're more than 6 months behind on child support payments or owe more than $1,000 in arrears. The process is administrative, you receive a notice, and if you don't respond within 20 days, the license is suspended without a court hearing.

But driver's licenses are just the beginning. DCS can also certify you to the relevant licensing boards for suspension of:

• Professional licenses (attorneys, doctors, nurses, realtors, contractors)
• Business licenses
• Commercial Driver's Licenses (CDL)
• Hunting and fishing licenses

For many professions, license suspension is functionally a career-ending event that makes it literally impossible to earn the income to pay the support obligation. Courts recognize this paradox, which is why many enforcement actions include a "payment plan to maintain license" option. But you must proactively contact DCS and set that up, it won't happen automatically.

4. Passport Denial and Revocation

Once you owe more than $2,500 in child support arrears, DCS can certify you to the federal government for passport denial or revocation. The U.S. State Department will not issue or renew your passport until the arrearage is resolved.

This is purely administrative, no court hearing, no appeal process before it happens. If you have international travel for work, are planning a vacation, or need to visit family abroad, discovering your passport is denied at the border is both humiliating and logistically catastrophic. Don't let it get to this point.

5. Federal Tax Intercept Program

If your federal tax refund is coming, and you owe more than $150 in child support arrears (or $500 if the custodial parent is not on public assistance), the Federal Tax Refund Offset Program will automatically redirect your entire refund, up to the full amount owed, to DCS. You'll receive a notice afterward.

The interception happens before you see a dime. If your new spouse's income contributed to the refund, they can file an "Injured Spouse" claim with the IRS to recover their portion, but it takes months and requires documentation.

6. Contempt of Court: The Nuclear Option

When administrative tools aren't working, usually because a parent is hiding income, working under the table, or actively avoiding payments, DCS or the custodial parent can file a Contempt of Court motion. The non-paying parent is brought before a judge to explain why they haven't complied with the court order.

If you can't show the court that (a) you didn't have the ability to pay, or (b) you've made a good-faith effort to pay as much as you could, the consequences can include:

• Fines of up to $1,000 per violation
• Payment of the other party's attorney's fees
• Community service hours
• Jail time of up to 6 months

Courts generally don't want to jail parents, jailed parents can't earn money to pay support. But for deliberate and sustained non-payment by parents who clearly have income, judges do impose incarceration. Washington courts consider this a tool of last resort, not a punishment, but that distinction matters a lot less when you're sitting in a cell.

7. What You Can Actually Do If You Fall Behind

If your income has genuinely changed and you're struggling, the single most important step is to file a Petition to Modify your support order immediately. Don't wait. Don't hope it'll work itself out. Every day you wait is another day of arrears accruing at 12% interest that you can never claw back.

Use our Worksheet Wizard to calculate what your support should be at your new income level. Then file the modification petition and ask for a temporary order modification at the first available hearing. If your income drop is documented and legitimate, courts move reasonably quickly on temporary orders.

You can also contact DCS directly to set up a payment plan on existing arrears. DCS would rather receive something consistently each month than go through the expense of license suspension and court proceedings.

Final Thoughts

Washington's child support enforcement system is designed to make avoidance expensive and difficult. The 12% interest rate and no statute of limitations mean unpaid support just keeps growing. The most expensive thing you can do is nothing. Run your current numbers through our calculator, determine whether you're overpaying or underpaying, and if there's a problem, file a modification today, not next month.
