Federal Garnishment Caps & Payroll Garnishment Limits Overview

Federal law sets maximum withholding amounts for wage garnishments, protecting a portion of every paycheck while allowing creditors, child support agencies, and tax authorities to collect what they're owed. Understanding payroll garnishment limits is essential for HR teams managing withholdings across different garnishment types and jurisdictions.

Three garnishment types carry different federal limits

Federal law sets different maximum withholding percentages for each major garnishment category. Child support orders allow the highest withholding — 50% of disposable earnings when the employee supports a second family, or 60% when they don't; either cap rises measurably if the employee is 12 or more weeks in arrears. Federal tax levies use a standard floor: the IRS may take everything above a base amount that equals your filing status exemption plus standard deduction, divided by pay periods (often leaving around 15% after subtractions). Creditor garnishments for debts like student loans, credit cards, or medical bills are capped at 25% of disposable earnings or the amount by which weekly disposable earnings exceed 30 times the federal minimum wage, whichever is less.

These federal limits exist to protect employees from having their entire paycheck seized while still honoring the obligations owed to dependents, tax authorities, and creditors.

When you process a garnishment, apply the type-specific cap before any other voluntary deductions, and always calculate disposable earnings (gross minus mandatory withholdings like FICA and income tax) as your starting figure.

State laws often impose stricter caps than federal limits

When state law sets a lower garnishment ceiling than federal limits, the employee receives the benefit of the stricter protection. An employer in California facing a consumer debt garnishment cannot withhold the full 25% federal maximum because state law caps it at 25% or the amount by which weekly disposable earnings exceed 40 times the state minimum wage, whichever is less.

The hierarchy is simple: federal law establishes the floor, and state law may raise the bar further to protect workers.

Payroll teams that misapply the looser standard expose the company to penalties, back-payment claims, and employee trust issues. Always compare both limits and apply whichever leaves the employee with more take-home pay.

Child Support Garnishment Payroll Setup

Setting up child support garnishments begins the moment you receive a court-issued wage garnishment notice. This document authorizes the withholding—verbal requests from an ex-spouse or a caseworker do not. Before you touch payroll, verify that the order includes:

The court seal
The employee's name and Social Security number
The monthly support amount
The remittance address for the state disbursement unit

Next, calculate disposable income. Gross pay minus federal and state income tax withholding, Social Security, Medicare, and any health insurance premiums the employee pays. Do not subtract voluntary deductions like 401(k) contributions or parking fees. The garnishment cap is 50 percent of disposable income for employees supporting a second family, or 60 percent if they are not. If the employee is twelve weeks or more in arrears, add five percentage points to either cap.

Cross-reference your state's threshold. Some jurisdictions impose lower caps or additional withholding conditions that override the federal percentages. Document the order in payroll records with the case number, effective date, and remittance details, then set up the recurring deduction for each pay period. Run a test calculation before the first live paycheck to confirm the withholding respects both the court amount and the disposable-income cap—whichever is lower protects the employee and keeps you compliant.

Federal Tax Levy Limits & Payroll Implementation

Tax levies arrive from the IRS or state revenue departments, not courts, and they carry their own procedural rules. When the IRS issues Form 668-W (Notice of Levy on Wages, Salary, and Other Income), it directs you to withhold a fixed percentage of each paycheck until the debt is satisfied or the levy is released. The federal standard is 15 percent of gross pay. But exemption tables can adjust that figure based on the employee's filing status and number of dependents. State tax levies follow similar logic but may use different percentages and priority rankings, so you'll verify each notice carefully.

Tax levies are continuous. Once you receive a valid Form 668-W or state equivalent, you process the withholding in every subsequent pay period until the issuing authority tells you to stop. That means tracking levy start dates, verifying receipt of release notices, and documenting each deduction in your payroll records. In the garnishment priority queue, tax levies outrank most creditor claims but usually sit behind child support orders, so if both arrive for the same employee, child support is withheld first and the tax levy applies to any remaining disposable earnings.

Creditor Garnishment Wage Garnishment Rules & Caps

Creditor garnishments arrive only after a court judgment. A collection agency's demand letter or notice of debt does not authorize payroll withholding — HR must see a signed court order naming your employee, the creditor, and the garnishment amount or percentage. Verify the issuing court, the case number, and the effective date before you touch payroll. If the paperwork lists only a settlement agreement or a payment plan offer, it is not a garnishment order and no deduction is permitted.

Federal law caps creditor garnishments at 25 percent of disposable income or the amount by which weekly disposable income exceeds 30 times the federal minimum wage. Whichever leaves the employee more money. Disposable income is gross pay minus required withholdings — income tax, Social Security, Medicare — but not voluntary deductions like 401(k) contributions or health premiums. Run both calculations every pay period and withhold the smaller result.

When an employee carries multiple garnishments simultaneously, sequence matters. The order is:

Child support withholding processes first
Federal or state tax levies follow
Creditor garnishments last

If disposable income is exhausted by higher-priority orders, the creditor garnishment waits until those obligations clear or income rises. Many states impose lower percentage caps or extend the notice period before withholding begins, so cross-reference your state's threshold before you process the first deduction. The most protective rule wins.

State Garnishment Caps & Compliance

Payroll professionals managing employees across multiple states face a compliance challenge: every state adds its own layer of garnishment law on top of the federal baseline. State law frequently provides additional employee protections, and in some cases eliminates entire garnishment categories. Knowing which state garnishment caps apply — and when they override federal limits — is the only way to withhold the correct amount and avoid both employee disputes and legal exposure.

Eight states prohibit or severely restrict creditor garnishments altogether. Texas, Pennsylvania, South Carolina, and North Carolina bar wage garnishment for consumer debts entirely. Florida limits creditor garnishment to heads of household earning below a threshold, while South Dakota and North Dakota impose strict procedural barriers. Louisiana caps creditor claims at the lesser of 25 percent or a dollar amount tied to minimum wage. HR teams processing creditor orders in these states must verify exemptions before any withholding begins.

Child support garnishment caps also vary by state. Many states impose caps below the federal 60 percent ceiling, apply income thresholds that phase out higher withholding, or require additional prior notice periods before the order takes effect. California, for example, uses a different disposable-income formula and imposes stricter arrearage caps. State tax levies operate independently of federal levies, meaning an employee may face both an IRS levy and a state revenue department levy simultaneously, each calculated under separate exemption tables.

Multi-state employers must maintain a state-by-state cap matrix and apply the most protective rule for each employee's work location.

When federal and state caps conflict, the lower withholding amount always governs.

This matrix becomes part of every garnishment setup checklist. Cross-referenced before the first payroll run touches the employee's net pay.

How to Process Garnishments Payroll & Error Avoidance

Once you understand the caps, the next challenge is executing garnishments correctly every pay period. A solid process starts when the order arrives: record the date received, garnishment type, issuing authority, and calculation basis in your payroll documentation. Validate that the order comes from a legitimate court or agency — this single check prevents paying unauthorized claims.

Calculate disposable income using the formula covered earlier, then apply the correct federal and state caps. Child support and tax levies often take priority, so if multiple garnishments arrive, flag them for priority sequencing and consult legal counsel or a third-party processor when stacking creates conflicts. Recalculate disposable income quarterly or whenever pay structure changes — a raise, a shift from hourly to salary, or a benefits adjustment all affect the cap.

Three common mistakes trip up even experienced payroll teams:

Failing to verify court authority before withholding leaves you exposed to liability if the order is invalid
Miscalculating disposable income by starting with gross instead of after-tax earnings leads to over-garnishment and employee disputes
Ignoring state caps that fall below federal thresholds violates the rule that the lower limit always applies

Document expiration dates for each order and update your payroll system when they lapse — continuing to withhold after an order expires is a costly error that requires refunds and paperwork.
