HR Fast Facts: What Is Allowable Disposable Income for Child Support Garnishments?
The following is a guide for calculating the amount of allowable disposable that may be garnished during a worker's pay period. Allowable disposable income is calculated by multiplying a worker's disposable income by the CCPA percentage limit. (Allowable Disposable Income = Disposable Income x CCPA % Limit) Allowable disposable income is the most a worker’s wages may be garnished. The amount that can be garnished is dependent on disposable income and the Consumer Credit Protection Act (CCPA) percentage limit. This in effect sets a maximum limit on the percentage that may be garnished in a pay period. CCPA % limit is an amount determined at a federal level and sets the maximum percentage that may be garnished. Disposable income is the portion of an worker’s paycheck that is subject to garnishments. Taxes and legally-required deductions don’t count towards disposable earnings. Voluntary deductions such as 401(k) contributions and health and life insurance are generally considered part of disposable income. These restrictions may vary by state; each court order for child support should cite any applicable state regulations. (Disposable Income = Gross Pay - Allowable Deductions) Wages that are eligible for garnishments include any normal pay, as well as any commissions or bonuses a worker may receive.
