Child support garnishment in California is automatic: every support order comes with an earnings assignment that tells your employer to withhold the payment directly from your paycheck. Federal law caps the withholding at somewhere between 50% and 65% of your disposable earnings, depending on whether you support another family and whether you’re behind on payments.1Office of the Law Revision Counsel. United States Code Title 15 Section 1673 – Restriction on Garnishment California’s Family Code fills in the mechanics — what income counts, when withholding starts, and how you can push back.
How Much of Your Paycheck Can Be Taken
The ceiling is set by the federal Consumer Credit Protection Act and applies as a percentage of your disposable earnings, meaning what’s left after mandatory deductions like federal and state income tax, Social Security, Medicare, and State Disability Insurance.2U.S. Department of Labor. Fact Sheet 30 – Wage Garnishment Protections of the Consumer Credit Protection Act There are four tiers:
- 50% if you currently support another spouse or dependent child not covered by the order.
- 60% if you do not support another spouse or dependent child.
- 55% if you support another family and are more than 12 weeks in arrears.
- 65% if you don’t support another family and are more than 12 weeks in arrears.
These are ceilings, not target amounts. Your actual withholding is whatever the court ordered for current support plus any arrearage payment, up to those limits. The 5% bump for arrears older than 12 weeks catches many people off guard. If you’ve been paying short or missing payments for several months, the withholding can jump from 50% to 55%, or from 60% to 65%, with no new court hearing.
How the Withholding Reaches Your Paycheck
California requires courts to attach an earnings assignment order to every new or modified child support order.3California Legislative Information. California Code FAM 5230 – Earnings Assignment Order for Support The local child support agency or the custodial parent serves your employer with a standardized federal Income Withholding Order (form FL-195), which carries the same legal force as the court’s earnings assignment.4California Courts. Income Withholding for Support FL-195
Once served, your employer must begin withholding no later than the first pay period that falls 10 days after service.5California Legislative Information. California Code FAM 5233 – Commencement of Withholding Withheld amounts go to the State Disbursement Unit, which then routes payment to the custodial parent.6California Child Support Services. Income Withholding Order Employer Guide The withholding continues automatically until the employer is served with a termination notice; your employer cannot stop just because you ask.
A child support earnings assignment takes priority over almost any other garnishment on the same paycheck.7California Legislative Information. California Code FAM 5243 – Priority of Assignment Order If a credit card company already has a wage garnishment in place and a support order arrives, the support order jumps to the front. The one exception is a federal tax levy served before the support order, which can keep its priority.
One more protection worth knowing: federal law bars any employer from firing you because your wages are being garnished for a single debt, and a child support withholding order counts as one debt no matter how many payments it covers over time.8Office of the Law Revision Counsel. United States Code Title 15 Section 1674 – Restriction on Discharge From Employment by Reason of Garnishment
What Income Is Reachable
California defines income for child support very broadly. It covers commissions, salaries, bonuses, royalties, rents, dividends, pensions, trust income, annuities, severance pay, and spousal support received from someone outside the case.9California Legislative Information. California Code FAM 4058 – Annual Gross Income Government benefits not based on financial need also count, including Social Security, State Disability Insurance, unemployment, workers’ compensation, veterans benefits not based on need, and military housing and food allowances.
Two categories are excluded: child support you receive for children from another relationship, and public assistance where eligibility depends on financial need.
Bonuses and Lump-Sum Payments
One-time payments don’t escape withholding. Bonuses, severance, commissions, retroactive pay increases, sign-on bonuses, and vacation payouts are all subject to child support collection.10Administration for Children and Families. Bonus/Lump Sum Reporting Employers are asked to report upcoming lump sums through the federal Child Support Portal so agencies can intercept the correct amount before the money reaches you.
Self-Employment and Contract Income
If you work for yourself, there’s no employer to receive the withholding order, but your income is not out of reach. California courts can issue orders directly to your clients requiring them to send payments to the child support agency instead of to you. Courts can also levy bank accounts and intercept other assets for past-due amounts.
For calculation purposes, self-employment income is gross business receipts reduced by expenses necessary to run the business. If a court believes you’re underreporting or voluntarily reducing your earnings, it can impute income based on your earning capacity, taking into account your work history, skills, education, health, and the local job market.
If You Think the Order Is Wrong: Motion to Quash
You can file a motion to quash the earnings assignment, but California limits the grounds to three specific situations: the order states the wrong support amount, you are not the person who owes the support, or the amount being withheld exceeds the federal maximum limits.11California Legislative Information. California Code FAM 5270 – Motion to Quash Assignment Order
The deadline is tight. You must file within 10 days of receiving your copy of the assignment from your employer, and the motion must be made under oath.12Judicial Council of California. Request for Hearing Regarding Earnings Assignment FL-450 If the same order later gets served on a new employer after you change jobs, you generally cannot re-raise objections you already had a chance to bring the first time around.
If the Amount Is Legal but You Can’t Survive It: Claim of Exemption
A motion to quash addresses legal errors. A claim of exemption addresses financial hardship. Even when the withholding amount is within the legal limits, you can ask the court to reduce the garnishment percentage on the ground that it prevents you from covering basic necessities for yourself and any other dependents you support. The court weighs whether to reduce the withholding while still meeting as much of the support obligation as possible. Waiting weeks after your employer begins withholding weakens your position, so file promptly.
If Your Circumstances Changed: Modify the Underlying Order
If the garnishment is crushing you financially, contesting the withholding only addresses the mechanics of collection. The real lever is modifying the underlying support amount. California allows either parent to request a modification at any time by showing a material change in circumstances, such as a job loss, a significant pay cut, a disability, or a new dependent.13California Legislative Information. California Code FAM 3651 – Modification of Support Orders
The critical detail: a modification can only reduce amounts going forward from the date you file the motion. It cannot erase arrears that piled up before you filed. This is where people get into serious trouble. They lose a job, assume the court will understand, and wait months before filing anything. Every month you delay is another month of the full support amount accruing as debt you’ll never be able to modify away. If your income drops, file immediately.
What Falling Behind Adds on Top
Unpaid child support in California accrues interest at 10% per year, beginning on the first day of the month after a payment was due and compounding on the entire unpaid balance. That rate applies automatically without any court action.
California also imposes a separate penalty on delinquent payments. Once a notice of delinquency is filed and served, any amount that remains unpaid for more than 30 days triggers a penalty of 6% per month, capped at 72% of the outstanding balance. These accumulate quickly and can turn a manageable debt into an overwhelming one within a year.
Enforcement reaches beyond your paycheck. Your driver’s license can be suspended if you fall behind and your income exceeds 70% of the median income for your county. A 2025 law shields lower-income parents from driver’s license suspension, but the protection does not extend to professional, occupational, or recreational licenses, which remain at risk.14California Child Support Services. Driver’s License The federal government can deny or revoke your passport if you owe more than $2,500 in back support, and unpaid support gets reported to credit bureaus.
What the Garnishment Doesn’t Change
Child support payments are not tax-deductible for the paying parent and are not taxable income for the receiving parent.15Internal Revenue Service. Tax Information for Non-Custodial Parents Whether you pay voluntarily or through wage withholding, neither side reports child support on their tax return.
Filing for bankruptcy won’t stop the garnishment either. The Bankruptcy Code explicitly exempts child support collection from the automatic stay that normally freezes creditor actions. Wage withholding for support continues during bankruptcy, as does license suspension, tax refund interception, and credit reporting of overdue support.16Office of the Law Revision Counsel. United States Code Title 11 Section 362 – Automatic Stay Child support debt is also non-dischargeable, so it survives bankruptcy entirely. You’ll still owe every dollar when your case closes.
