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)).

Missouri points to the federal CCPA ceiling

Section 454.505 prevents administrative withholding from exceeding 15 U.S.C. §1673(b).

The ceiling depends on another supported family and whether arrears exceed twelve weeks.
