If your employer hasn't paid your final wages, this page lays out exactly what Iowa law requires, what it costs your employer to ignore it, and how a properly cited demand letter invokes both. Every deadline, penalty, and citation below was verified against the current statute text or official state guidance.

Iowa's final paycheck deadlines at a glance

If you were fired or laid off Next regular payday for the period in which wages were earned
If you quit Same one rule (fired, laid off, quit identical); commissions get a 30-day calculation window
The penalty for nonpayment Liquidated damages of 5% per day (excl. Sundays, holidays, and the first 7 days), capped at 100% — plus fees regardless of intent

When your final paycheck is due in Iowa

One rule for every separation: wages are due by the next regular payday for the period in which they were earned (Iowa Code § 91A.4). Commission calculations get a 30-day window.

What late payment costs your employer

Iowa defines the meter verbatim: "liquidated damages" equal 5% of the unpaid wages for each day unpaid, EXCLUDING Sundays, legal holidays, and the first SEVEN days after the payday — capped at 100% of the wages (§ 91A.2(6)). Under § 91A.8, intentional nonpayment yields wages + liquidated damages + costs + attorney fees; even NON-intentional failures yield wages + costs + fees. The meter halts on a bankruptcy petition.

Why the demand letter matters in Iowa

THE IGNORED DATED DEMAND IS THE INTENTIONALITY EVIDENCE that unlocks the liquidated-damages meter — and because fees flow to the prevailing employee regardless of intent, even a $300 shortfall is economical to chase.

Vacation and PTO in the final check

Vacation counts as wages when policy provides pro-rata payout.

What a strong Iowa demand letter looks like

An effective Iowa letter does the following: run the math in the letter: after the 7-day grace the debt doubles in roughly 20 working days. Add the overdraft clause — if the late check caused bank fees and the employer was on notice, those are recoverable too (§ 91A.3(3)(b)). Iowa Workforce Development is the agency route; 2-year lookback. Here's how the opening of a strong one reads:
