Iowa New Hire Reporting: 15-Day Deadline, What to Report and How to File (2026)

Iowa employers must report each new or rehired employee to the Iowa Centralized Employee Registry within 15 days, five fewer than the federal limit, including the employee’s date of birth and dependent health coverage details. Independent contractors must also be reported, within 15 days of being paid above the 1099-MISC filing amount other than as a lump sum. File online through Iowa’s employer child support website or by mail or fax; a willful failure is punishable as contempt under Iowa Code 252G.3.

Iowa departs from the federal model in four ways. It gives employers 15 days instead of 20, it requires independent contractor reports, it makes the employee’s date of birth mandatory, and it uses a six-week rehire test. The registry behind it is the Iowa Centralized Employee Registry, run by child support services at the Iowa Department of Health and Human Services under Iowa Code chapter 252G. For the federal rules and a comparison with other states, see our new hire reporting requirements by state.

Iowa new hire reporting at a glance

Fifteen days, and what starts them

Iowa Code 252G.3 requires employers to report the hiring or rehiring of an employee within fifteen days, and 252G.1 says days means calendar days. The date of hire is the first day for which the employee is owed compensation. Employers reporting magnetically or electronically may instead report through transmissions not less than twelve nor more than sixteen days apart.

Fifteen days changes the arithmetic for employers that batch paperwork. A company that runs new hire reports with a two-week payroll cycle is already at 14 days before anyone touches the file. A weekly batch, or a report triggered by the first timecard, keeps Iowa hires inside the window even when orientation slips a few days.

The Iowa data list

Iowa’s report is longer than the federal one. The statute requires:

• Employer name, address and federal identification number
• Employee name, address, Social Security number and date of birth
• Whether the employer has dependent health care coverage available, and the approximate date the employee may qualify
• The address where income withholding orders or garnishment notices should be sent

The New Hires FAQ (revised October 2024) adds the employee’s start date and the location where the individual works. On the health question, answer Yes if a family health insurance policy is available to the employee regardless of cost, and Yes if the union rather than the company provides coverage.

Filing a report in Iowa

Online reporting runs through Iowa’s Employer Child Support Website, where registered employers can enter one employee, several at once, or, with advance permission and test files, use the upload process. The same site handles child support payments, electronic income withholding forms and termination reports.

Paper filers mail or fax the Iowa employee’s withholding allowance certificate (the IA W-4, available from the Iowa Department of Revenue), or the Centralized Employee Registry Contractor Reporting form for contractors. Complete one form or the other for each person, never both. Mail to Iowa Centralized Employee Registry, PO Box 10322, Des Moines IA 50306-0322; fax 800-759-5881 or 515-281-3749. A federal W-4 can be sent for the basic items, but the statute requires the remaining Iowa items to be reported by one of the other permitted methods.

Contractors: Iowa’s biggest difference

Iowa Code 252G.4 requires a payor of income that engages a contractor to report that contractor within fifteen days of the date both conditions are met: the payor issues payment above the amount that triggers a 1099-MISC filing, and payment under an agreement is made in a form other than a lump sum within a calendar year. The FAQ puts the second test as paying the contractor twice a year or more under one agreement.

Iowa defines a contractor narrowly: a natural person 18 or older who performs labor in Iowa, receives payments not subject to withholding, and for whom the payor must file a 1099-MISC. Corporations, partnerships and other entities are excluded. A contractor is reported only once, and the date of birth is required only when known. Because the statute ties the threshold to the IRS filing amount rather than a dollar figure, check the current IRS threshold rather than relying on an older number.

Penalty: a court action, not a fine schedule

Iowa does not set a per-report fine. Under 252G.3(5), if an employer fails to report, a state agency that uses or runs the registry, or the attorney general, may bring an action in district court, in the county of the employer’s principal place of business, a county where an employee works, or Polk County. A willful failure to provide the information is punishable as contempt. The same penalty applies to payors that fail to report contractors.

Rehires: six consecutive weeks

Iowa’s rehire definition is written in weeks, not days. Under 252G.1, a rehire is the first day an employee is owed compensation following a termination of employment lasting at least six consecutive weeks. Unpaid medical leave, an unpaid leave of absence and a temporary layoff are not terminations. The FAQ describes a rehire as someone you did not expect to work for you again.

Workers from a temporary agency are the agency’s responsibility to report, not the client’s. For seasonal employers, the test is whether the worker was genuinely terminated for six weeks or more, not merely laid off with an expected return.

Who sees an Iowa report

Iowa Code 252G.5 makes registry records confidential and limits access to child support services, state agencies that use income data to decide benefit eligibility, and the agencies running employment security and workers’ compensation. Under 252G.6, the registry keeps the information for at least six months. The practical effect for employers is the same as everywhere: a report that matches a support order comes back as an income withholding order.

Employers in several states

An employer with employees in two or more states that transmits electronically may report to each state or designate one, after notifying the U.S. Secretary of Health and Human Services in writing (252G.3(4)). The details are on our multistate reporting guide.
