Iowa Payroll Tax Guide (2026)
Iowa’s headline payroll change for 2026 is not the tax rate but the unemployment wage base, which fell from $39,500 to $20,400, while Contribution Rate Table D keeps employer rates between 0.000% and 5.400% and the income tax holds flat at 3.8%.[7]
Iowa payroll at a glance
Iowa employers deal with two state payroll taxes: a flat 3.8% individual income tax withheld from wages and employer paid unemployment insurance contributions. Employees make no state unemployment, disability or paid leave contribution.[7]
What changed for Iowa payroll in 2026
Six items moved for Iowa employers this year. Anything below is what have changed since the 2025 tables, so a rate card carried over from last year will be wrong in at least one place.

Employer pays
Withheld from the employee
State income tax withholding is not included above: it depends on the employee’s Form IA W-4 (44-019) and filing status, so it cannot be estimated from gross pay alone.
Payroll tax rates & the nexus question
Iowa runs two state payroll taxes. The table below is the whole state layer for 2026.[7]
The state payroll taxes
| Tax | Paid by | 2026 rate | Wage base |
|---|---|---|---|
| UI | Employer | 0.00%–5.40%; 1.00% new | $20,400 |
| Income tax withholding | Employee | 3.80% flat | No limit |
Contribution Rate Table D, the lowest rate table allowed by law, applies for 2026. Iowa now uses four tables of nine ranks each, with rates from 0.000% to 5.400%.[7]
Who has to register
A general business or 501(c)(3) becomes liable once it pays wages in any calendar quarter in the current or preceding calendar year. Agricultural employers become liable at $20,000 of gross wages in a quarter or ten workers in 20 separate weeks, and domestic employers at $1,000 paid in a quarter.[7] Income tax withholding is administered separately by Iowa Department of Revenue, so most employers end up with two state account numbers, not one.
Multistate and remote employees
When an employee works in more than one state, the four-part test below decides which state the wages are reported to. The tests run in order: you stop at the first one that gives an answer.
- 1. Localisation of service→
- 2. Base of operations→
- 3. Place of direction & control→
- 4. Employee’s residence
One remote employee is usually enough. A single person working from home in Iowa generally creates an obligation to register and report wages here, even if the business has no office, property or customers in the state.

A general business or 501(c)(3) becomes liable once it pays wages in any calendar quarter in the current or preceding calendar year. Agricultural employers become liable at $20,000 of gross wages in a quarter or ten workers in 20 separate weeks, and domestic employers at $1,000 paid in a quarter.[7]
Deposit schedule
Projected annual Iowa withholding sets the schedule. Under $6,000 a year you file and pay quarterly by the last day of the month following the quarter. From $6,000 to $120,000 you file quarterly and pay monthly by the 15th. Over $120,000 you file quarterly and pay semimonthly on the 10th and 25th.[2]
Returns, reports & due dates
| Form | What it is | Due |
|---|---|---|
| Employer’s Contribution and Payroll report | Quarterly unemployment return | April 30, July 31, October 31, January 31 |
| Quarterly withholding returns and payments are made through GovConnectIowa, and W-2… | Income tax withholding returns | Projected annual Iowa withholding sets the schedule. Under $6,000 |
| Annual reconciliation | Year-end withholding reconciliation | February 15 |
| Form 941 | Federal quarterly return | Last day of the month after quarter end |
| Form 940 | Federal unemployment, annual | January 31 |
| New hire report | Report of newly hired employees | Within 20 days of start date |
Quarterly unemployment returns are due April 30, July 31, October 31, January 31. A return filed one day late is delinquent, and in most states the penalty attaches to the return, not the payment.[7]

Subject wages vs. exempt payments
Not every dollar an employee receives is a taxable wage. The split below governs what goes into the unemployment wage base and what is reported at year end.[7]
Subject wages
- Salaries, hourly pay, overtime and piece rates
- Commissions, bonuses and incentive pay
- Most cash tips reported by the employee
- Vacation, holiday and paid sick leave when taken as wages
- Severance and payments in lieu of notice
- The cash value of meals and lodging provided as compensation
- Employer contributions to a non-qualified deferred compensation plan
Not subject
- Reimbursements of genuine business expenses under an accountable plan
- Employer contributions to a qualified retirement plan
- Employer-paid premiums for accident and health insurance
- Most third-party sick pay after the sixth calendar month
- Payments to a genuine independent contractor
- Workers compensation benefits
The wage base is per employer, per year, not per job. If you hire someone in August who already earned $20,400 elsewhere, your unemployment clock still starts at zero. The one exception is a successor employer taking over an existing payroll, who inherits the wages already paid.
Glossary of key terms
- Taxable wage base
- The slice of each employee’s annual pay that unemployment tax is calculated on. In Iowa that is $20,400 for 2026. Earnings above it are still wages, they are simply no longer taxed for unemployment.
- Experience rating
- The method Iowa Workforce Development uses to set each employer’s own unemployment rate from its history of claims. Employers with fewer charged claims move down the schedule; those with more move up.
- New employer rate
- The rate assigned before an employer has enough history to be experience rated. It normally applies for two to three years, then the account moves onto the experience schedule.
- Form IA W-4 (44-019)
- The state withholding certificate. It sets how much income tax comes out of each cheque and is filed with the employer, not with Iowa Department of Revenue.
- Reserve account
- The running balance of contributions an employer has paid in, less the benefits charged against it. The ratio of that balance to taxable payroll is what drives the assigned rate.
- Successor employer
- A business that acquires another’s payroll may inherit both its experience rate and the wages already paid toward the wage base for the year. Getting this wrong is a common acquisition error.
- Localisation of service
- The first of four tests deciding which state a multistate employee’s wages are reported to. If substantially all the work is in one state, that state wins and the remaining tests are never reached.
- FUTA credit reduction
- A reduction in the 5.4% federal unemployment credit applied to states that have carried an outstanding federal loan for two or more consecutive Januaries. It raises the effective FUTA rate and is settled each November.
- Supplemental wages
- Bonuses, commissions, awards and similar payments made outside the regular payroll cycle. Many states set a separate flat withholding rate for them.
Iowa payroll tax, layer by layer
Federal tax applies everywhere and is the larger number. The state layer is what changes when you cross a border.
Layer 1: Federal
| Tax | Rate | 2026 base |
|---|---|---|
| Social Security | 6.2% each side | $184,500 |
| Medicare | 1.45% each side | No limit |
| Additional Medicare | 0.9% employee only | Over $200,000 |
| FUTA, standard | 0.6% net | $7,000 |
| Federal income tax | Per Form W-4 | No limit |
Iowa has no FUTA credit reduction for 2026, so the standard 0.6% net rate applies, $42 per employee. The final list is not published until 10 November 2026.[14]
Layer 2: State
| Tax | Rate | 2026 base |
|---|---|---|
| UI, new employer | 1.00% | $20,400 |
| UI, experienced | 0.00%–5.40% | $20,400 |
| Income tax, standard | 3.80% flat | No limit |
Layer 3, county & city: no payroll tax, but a wage floor
No county or city in Iowa levies its own payroll or income tax withheld by employers. The local layer shows up as minimum wage, not as tax.[11]
The state minimum wage is $7.25 an hour, which is the federal floor, effective 2026-01-01. The tipped cash wage is $4.35. No local ordinance sets a higher floor. The federal wage and hour tables list a single statewide Iowa rate with no city or county minimum wage rates. Iowa’s tip credit is capped at 40% of the applicable minimum wage.[11]
Overtime exemption is a separate test. A salaried employee is exempt from overtime only above $35,568 a year ($684.00 a week) Federal FLSA standard salary level, and only if the duties test is also met. Paying a salary is not by itself enough.[13]
Iowa payroll FAQs
Iowa applies a single flat rate of 3.8% to all levels of taxable individual income for 2026. The withholding formula annualizes the wage, subtracts a deduction that varies by pay frequency and filing status, applies 3.8%, then subtracts the allowance amount claimed on the IA W-4.
It is $20,400 per employee, down sharply from 2025 because Senate File 607 reduced the base. Contribution Rate Table D is in effect, which is the lowest table allowed by law, with rates running from 0.000% to 5.400% across nine ranks.
A new non-construction employer is assigned the rank 4 rate from the table in effect but not less than 1.000%, which works out to 1.000% for 2026. A new construction employer is assigned the rank 9 rate, which is 5.400% for 2026.
It depends on projected annual withholding. Under $6,000 you file and pay quarterly. Between $6,000 and $120,000 you file quarterly and pay monthly by the 15th of the following month. Over $120,000 you file quarterly and pay semimonthly on the 10th and 25th.
February 15. Iowa does not accept paper W-2 wage and tax statements or 1099 information returns, so the files must be uploaded electronically through GovConnectIowa. Missing that date carries penalties separate from the withholding return itself.
No local income tax is withheld from Iowa wages and no Iowa city or county sets its own minimum wage. Employers withhold the flat 3.8% state tax only. The statewide minimum wage is $7.25, with a $4.35 cash wage for tipped employees and a tip credit capped at $2.90.
$7.25 an hour, which matches the federal floor. No local ordinance sets a higher rate. The tipped cash wage is $4.35.
April 30, July 31, October 31, January 31. A return is delinquent the day after the deadline even if the tax itself was paid on time, so file the return whether or not you can pay.
