Earnings

Weekly pay left after deductions required by law, such as taxes (15 U.S.C. 1672). Voluntary deductions still count as disposable.

Situation
Does the paying parent support another spouse or dependent child?
Do the arrears cover a period more than 12 weeks ago?

Maximum weekly withholding for support: $480.00

That is 60% of disposable earnings, the federal CCPA ceiling that applies to this situation (15 U.S.C. 1673(b)(2)).

Wisconsin applies the federal CCPA ceilings

The limits are 50 percent with a second family and 60 percent without one. DCF guidance uses 55 or 65 percent when past-due support meets the notice condition.

Disposable income is earnings left after federal, state, and local withholding taxes and Social Security and Medicare taxes.

If ordered deductions exceed the cap, employers follow Wisconsin priority: current support first, then spousal support, medical support, past-due amounts, and fees.
