CALIFORNIA SUPPORT GUIDELINES

How California Child Support Is Calculated

Family Code 4055 sets one statewide formula: CS = K[HN − (H%)(TN)]. HN is the high earner's net monthly disposable income, TN is both parents' combined net, H% is the share of time the children spend with the high earner, and K is the portion of income allocated to support. The current version took effect on September 1, 2024.

Net disposable income is not gross pay. Family Code 4059 subtracts state and federal income tax actually payable, FICA, state disability insurance premiums, health insurance premiums, and mandatory union dues or retirement contributions. Because the result depends on both parents and on time-share, this calculator starts from the amount in your order. The Department of Child Support Services publishes the official guideline calculator.

THE FORMULA IN ONE EXAMPLE

How Time-Share Moves a California Support Amount

Suppose the high earner has $5,000 a month in net disposable income and the other parent $3,000, with one child. Combined net of $8,000 puts the income fraction at 0.250, and the only thing that changes below is parenting time.

Illustration of Family Code 4055 for one child, before any add-ons or low-income adjustment. A court order or the DCSS calculator sets the real figure.
Time with high earner (H%)Income fractionKMonthly support
0%0.2500.250$1,250
20%0.2500.300$1,020
30%0.2500.325$845
50%0.2500.375$375

Moving from 20% to 50% of parenting time cuts this example by nearly two-thirds, which is why time-share comes up so often in California support cases.

PAYROLL WITHHOLDING

How Child Support Comes Out of Your California Paycheck

Support is withheld after taxes. Federal income tax, Social Security, Medicare, and any state and local income tax are figured on your full gross pay; the support deduction comes out of what is left.

The order reaches your employer as an Income Withholding for Support, also called a wage assignment. Your employer deducts the amount from each paycheck and sends it to the California State Disbursement Unit, and California businesses must pay electronically. When a check cannot cover everything, current support is paid first.

Family Code 5235 lets the employer take a further $1.50 from your earnings for each payment it makes under the order. On 26 bi-weekly paychecks that comes to $39.00 a year.

California's cap is simpler than the federal one. The Department of Child Support Services tells employers to withhold no more than 50% of net disposable earnings, without the federal 60% and 65% tiers. Code of Civil Procedure 706.052 uses the same one-half measure for support withholding orders, and lets a court order a different division on motion, within the federal limit.

STEP BY STEP

How Payroll Figures a California Child Support Deduction

The same steps the California paycheck calculator with child support follows, using a $75,000 salary paid bi-weekly and an $800 monthly order:

  1. Gross pay per check: $2,884.62.
  2. Subtract taxes required by law — federal $295.00, Social Security and Medicare $220.67, California $117.39, SDI $37.50 — to get disposable earnings of $2,214.06.
  3. Apply the California limit: 50% of disposable earnings is $1,107.03.
  4. Convert the order to this pay schedule: $800 × 12 ÷ 26 = $369.23, plus $1.50 for the California employer fee ($1.50 per payment).
  5. The order is under the limit, so $370.73 is withheld and $1,843.33 is paid to you.

DISPOSABLE EARNINGS

What Counts as Disposable Earnings in California

Disposable earnings are gross pay minus deductions required by law. Voluntary deductions stay in the base, so a large 401(k) contribution does not lower the California limit.

Disposable earnings follow the federal definition in 15 U.S.C. 1672, the one cited by California Code of Civil Procedure 706.052.

BONUSES AND JOB CHANGES

CHANGES

Changing Jobs or Pay With a California Support Order

Employers report new hires to the state, and the California Department of Child Support Services (DCSS) uses those reports to send the withholding notice to your new employer. Until the first deduction appears on a new pay stub, you remain responsible for paying the State Disbursement Unit directly, so a job change does not pause the order.

COMMON QUESTIONS

California child support Paycheck Questions

How much can be taken from a California paycheck for child support?+

California DCSS tells employers to withhold up to 50% of net disposable earnings. That is pay after federal and California income tax, Social Security, Medicare and SDI. If the order is larger, the employer sends what the limit allows and the rest becomes past-due support.

What is the $1.50 fee next to child support on my California pay stub?+

Family Code 5235 allows your employer to deduct $1.50 from your earnings for each support payment it makes. It is an employer processing charge, so it does not count toward your support balance. If you are paid bi-weekly and one payment goes out per check, that is $39.00 a year.

Does California SDI lower the amount that can be withheld for child support?+

A little. SDI is a required deduction, so it comes out before the 50% limit is applied. On $75,000, SDI is $37.50 per bi-weekly check, which lowers the limit by half of that. The order itself stays the same unless a court changes it.

How is child support calculated in California?+

With the Family Code 4055 formula, CS = K[HN − (H%)(TN)], using both parents' net disposable income and the time the children spend with the higher earner. The calculator on this page does not estimate that amount; it shows what your check looks like once the ordered amount is withheld.

Can a California bonus be taken for child support?+

Yes. DCSS says bonus and lump sum payments are considered income and may be garnished, and it lists commissions among the examples. Employers can report upcoming lump sums to DCSS, which may issue a separate Bonus/Lump Sum withholding order.
