Getting a garnishment notice feels like losing control of your own paycheck entirely — like whoever's owed money can simply take whatever they decide to take. That's not how garnishment actually works, and the gap between the fear and the rule matters a great deal.

Federal law limits how much of your income can be garnished, generally capping it at a percentage of your disposable earnings — what's left after legally required deductions, not your full gross pay. For most debts, that limit sits at 25 percent of disposable income, or the amount above a certain threshold tied to minimum wage, whichever is lower. Certain debts, like child support, have different limits, but even those aren't unlimited.

This means garnishment can't simply strip an entire paycheck down to nothing, regardless of how aggressive the creditor sounds. There's a real, legally protected floor of income that has to remain untouched, specifically so someone facing debt collection isn't left with literally nothing to live on.

Most people never check what the actual legal cap is before assuming the worst. Knowing the real limit — and confirming any garnishment order actually follows it — is the difference between panicking over an imagined worst case and understanding exactly what's actually allowed to happen to your paycheck.
