Iowa does something most states do not: in addition to the federal weekly limit on wage garnishment, Iowa places a hard annual cap on the total amount any one creditor can take from your wages in a calendar year, and that cap slides with your income. Under Iowa Code section 642.21, a single creditor with a money judgment cannot garnish more than a set dollar amount per year regardless of how much you earn each week. The current statutory tiers are: no more than $250 if your expected annual earnings are $12,000 or less; $400 if you earn $12,000 to under $16,000; $800 if you earn $16,000 to under $24,000; $1,500 if you earn $24,000 to under $35,000; $2,000 if you earn $35,000 to under $50,000; and 10% of your expected annual earnings if you earn $50,000 or more. So a worker making $30,000 a year can have at most $1,500 garnished by one judgment creditor for the whole year, even if the weekly math would otherwise allow more.
How Iowa's wage garnishment limits work
Iowa garnishment runs on two limits at once, and a creditor can only take the smaller result.
The first limit is the weekly cap, which mirrors the federal ceiling set by Title III of the federal Consumer Credit Protection Act (CCPA). For an ordinary debt, a creditor may take the lesser of (1) 25% of your disposable earnings for that week, or (2) the amount by which your disposable earnings exceed 30 times the federal minimum wage. "Disposable earnings" means what is left after legally required deductions such as federal and state taxes, Social Security, and Medicare. With the federal minimum wage at $7.25 per hour as of 2026, the 30-times figure works out to about $217.50 per week that is fully protected. Iowa's own minimum wage is also $7.25, so the federal floor controls. Because minimum-wage figures can change, confirm the current federal and Iowa rates before relying on a specific dollar amount.
The second limit is Iowa's annual aggregate cap under section 642.21, described above. This is the part that sets Iowa apart from states that rely only on the federal 25% rule. Once a creditor has collected up to your yearly tier amount, garnishment on that judgment must stop for the rest of the calendar year, even if you keep earning wages that the weekly formula would otherwise reach. The debtor is entitled to a written explanation of how the garnishment was calculated, and the law requires the garnishment to be applied so that the annual maximum is respected.
The two-limit example
Suppose you earn about $45,000 a year. The weekly formula might let a creditor take 25% of your disposable pay each pay period. But your annual tier caps the total at $2,000 for the year from that one judgment. The creditor takes the weekly amount only until the running total hits $2,000, then collection on that judgment pauses until the next calendar year. This annual ceiling is why Iowa is considered more debtor-protective than the bare federal standard for many wage earners.
Debts that are NOT limited the same way
The 25% weekly cap and the section 642.21 annual cap apply to ordinary consumer and commercial judgment debts. Several categories follow different, often higher, federal rules:
- Child support and spousal support. Under federal law, support orders can reach up to 50% to 65% of disposable earnings, depending on whether you support another family and how far behind you are. Iowa support enforcement uses these federal percentages, not the lower consumer cap.
- Unpaid federal taxes. The IRS does not use the 25% rule. It garnishes based on a table tied to your filing status and dependents, and can take a large share of wages.
- Federal student loans. The U.S. Department of Education and its guaranty agencies can use administrative wage garnishment of up to 15% of disposable pay without first suing you.
For these, do not assume Iowa's annual cap protects you, because they operate under separate federal authority.
What income is exempt in Iowa
Some money is protected before any garnishment math even applies, because it is exempt from creditors under Iowa Code chapter 627 and federal law. Commonly protected income and funds include:
- Social Security benefits, including retirement, disability (SSDI), and SSI
- Veterans' benefits and certain military pay
- Unemployment compensation
- Workers' compensation benefits
- Public assistance, including FIP and similar welfare benefits
- Most pension, retirement, and disability payments, including many private retirement plans
- Life insurance and certain support payments you receive
These exemptions matter even after the money lands in your bank account, but the protection is easiest to enforce when the funds are clearly traceable to an exempt source. Federal rules also require banks to automatically protect a baseline of directly deposited Social Security and certain federal benefits from garnishment. If exempt funds are mixed with non-exempt money in one account, you may have to prove which dollars are protected.
How to claim an exemption and stop or reduce garnishment
Garnishment in Iowa generally cannot happen until a creditor sues you, wins a money judgment, and then files for garnishment through the court. (Child support, tax, and student-loan garnishments are exceptions that can skip the lawsuit.) Once garnishment is sought, you have rights to challenge it:
- Read the notice carefully. Iowa requires that you be served with a notice telling you about garnishment, the exemptions available, and how to contest it. The notice states the deadline and the steps to respond. Act before that deadline, because missing it can waive your objection.
- File a claim of exemption with the court. If the garnished income or funds are exempt (for example, Social Security or wages already at the annual cap), promptly file the exemption claim described in your notice with the clerk of court. You can ask the court to release protected money.
- Point to the annual cap. If a creditor has already collected your section 642.21 yearly maximum, raise that directly; further garnishment by the same judgment for that year should not continue.
- Verify the disposable-earnings math. Garnishment must be based on disposable earnings, not gross pay. Errors here often mean too much is being taken.
- Consider a hearing. You can request a court hearing to resolve a disputed exemption. Bringing pay stubs, benefit award letters, and bank statements helps you prove the source of protected funds.
If garnishment is causing genuine hardship, you may also be able to negotiate a payment plan with the creditor, or speak with a bankruptcy or consumer attorney, since filing bankruptcy triggers an automatic stay that halts most garnishments immediately.
Federal protections that apply on top of Iowa law
Two federal laws back up your Iowa rights. The federal Fair Debt Collection Practices Act (FDCPA) bars third-party debt collectors from using abusive, deceptive, or unfair tactics, including threatening garnishment that is not legally available. The CCPA sets the nationwide 25% weekly floor of protection and forbids firing an employee because their wages were garnished for a single debt. Iowa builds on these federal baselines, and in the case of the annual cap, goes beyond them.
Where to verify the current rules
Because dollar tiers, minimum-wage figures, and procedures can change, confirm the details before you act. The Iowa Attorney General's Office, Consumer Protection Division publishes consumer guidance on debt collection and garnishment and accepts complaints about unlawful collection practices. The text of the garnishment limits lives in Iowa Code chapter 642 (especially section 642.21) and the exemption list in Iowa Code chapter 627, both available through the Iowa Legislature's official website. For court-specific forms and deadlines, check with the clerk of the Iowa district court in your county, or consult Iowa Legal Aid if you cannot afford a private attorney.

Frequently asked questions
What is the maximum a creditor can garnish from my wages in Iowa each year?
Under Iowa Code section 642.21, one judgment creditor's yearly total is capped on a sliding scale: as little as $250 a year if you earn $12,000 or less, up to $2,000 if you earn $35,000 to under $50,000, and 10% of your annual earnings if you earn $50,000 or more. This annual cap is in addition to the weekly limit.
Does Iowa follow the federal 25% wage garnishment limit?
Yes, for the weekly limit. An ordinary creditor can take no more than 25% of your disposable earnings, or the amount above 30 times the federal minimum wage (about $217.50 per week at the $7.25 rate in 2026), whichever is less. But Iowa also adds a yearly aggregate cap that the federal rule does not have.
Can Social Security or unemployment be garnished in Iowa?
Generally no. Social Security, SSI, SSDI, unemployment, workers' compensation, veterans' benefits, and most pensions and public assistance are exempt from garnishment for ordinary debts under Iowa and federal law. If these funds are garnished, file a claim of exemption with the court to get them released.
Do child support or student loan garnishments follow Iowa's caps?
No. Child and spousal support can reach 50% to 65% of disposable pay under federal rules, federal student loans can take up to 15% through administrative wage garnishment without a lawsuit, and IRS tax levies use their own table. Iowa's consumer caps do not limit these.
How do I stop a wage garnishment in Iowa?
Read the garnishment notice for your deadline, then file a claim of exemption with the clerk of court if the income is protected or the annual cap has been reached. You can request a hearing with proof such as pay stubs and benefit letters. Negotiating with the creditor or filing bankruptcy (which triggers an automatic stay) are other options.
