Wage Garnishment Manager: Withhold the Right Amount, in the Right Order, Every Time

Log every garnishment order, compute the per-period deduction within CCPA disposable-income limits, prioritize and cap when an employee has multiple orders, and route it for payroll approval before it ever hits a paycheck.

What you'll build

A web tool where you log each garnishment order with its terms, the tool computes the per-period deduction respecting CCPA caps and order priority, payroll reviews and approves the math, and you export a garnishment-deduction CSV plus a remittance summary per agency.

Before you start

  • A Supabase account (free)
  • A Vercel account (free)
  • A Resend account (free)
  • Your garnishment orders (type, amount/percentage, agency, priority)
  • Each employee's disposable earnings per pay period
  • Claude Code or any AI coding agent

The problem this kills

A garnishment order lands on your desk — a child-support withholding order, a state tax levy, a creditor judgment — and now you own a small minefield. You have to read the order's terms, figure out the employee's disposable earnings for the period, compute the deduction, and check it against the federal CCPA cap so you don't over-withhold. Then a second order arrives for the same employee and the real fun starts: child support has priority, the total can't blow past the disposable-income ceiling, and a creditor garnishment may have to be reduced or skipped entirely this period.

Get it wrong in either direction and it costs you. Under-withhold and the agency comes after the employer. Over-withhold and you've shorted an employee's paycheck — and you're the one who has to fix it. Most teams run this in a spreadsheet that nobody fully trusts, re-keying numbers under a payroll deadline. You don't need to live like this, and you don't need to be a developer to fix it.

What you'll build

A simple internal web tool. You log each garnishment order with its terms — type, the agency, the amount or percentage, the priority, and any balance to pay off. Each period you enter (or import) the employee's disposable earnings, and the tool computes the deduction the right way: it applies the correct CCPA cap for that order type, stacks multiple orders in priority order (child support first), and reduces or stops lower-priority orders so the combined withholding never exceeds the limit. It tracks balances so an order automatically terminates when it's paid off. Payroll opens a review screen that shows the computed deduction and exactly how it was prioritized and capped, fixes anything that looks off, and clicks Approve. Only then does the tool produce a garnishment-deduction CSV for payroll and a remittance summary per agency so you know who to pay and how much.

What's inside the Implementation Plan

The downloadable plan is a step-by-step file you paste into an AI coding agent. It opens by interviewing you about your business — which payroll system you run, your pay frequency, how you define disposable earnings, what kinds of orders you actually receive, your state's rules where they're stricter than federal, your typical and peak order volumes, and your messy edge cases — and then it tailors the data model, the cap math, the priority rules, and every later step to your answers. This is not a generic template; the agent reflects a short spec back to you and waits for your thumbs-up before it builds anything. From there it walks the agent through logging orders, the disposable-earnings import, the CCPA cap and multi-order priority engine, balance payoff and termination, the payroll review-and-approve screen, and the deduction-CSV and per-agency remittance exports — each step with a ready-to-copy prompt. There's also a fallback so you can build the whole thing today even with no API to your payroll system.

The governance it includes (this is the point)

This is real payroll-compliance tooling, so it ships with the controls a payroll team needs: login so only your team can use it, row-level security so you only ever see your own organization's employees and orders, a complete audit trail of who computed, reviewed, and approved which deductions and when, a hard human-approval gate so no deduction is finalized until payroll signs off on the priority and cap math, and duplicate guards keyed on employee + order so the same order can't be logged or deducted twice. Caps are enforced by the engine, not by memory — so a combined withholding can never silently exceed the CCPA limit.

Who it's for

Payroll specialists, payroll managers, and HR/payroll teams who receive garnishment orders and have to withhold exactly the right amount, in the right priority, without over-deducting. If you can describe how your shop reads an order and computes a deduction today, you can build this.

You've got this — start with the plan, paste the first prompt, answer the interview, and you'll see your first capped, prioritized deduction computed the same afternoon.
