Wisconsin Payroll Compliance Guide 2026

Wisconsin's payroll environment sits in the moderate complexity range. A graduated income tax with a top rate of 7.65% requires bracket calculations for withholding. The SUI wage base of $14,000 is above the federal FUTA floor but below the extremes of states like Washington. The one distinctly Wisconsin feature is the state's own Family and Medical Leave Act, which operates alongside the federal FMLA at companies with 50 or more permanent employees and provides leave rights that differ from the federal law in specific ways.

Wisconsin has held its minimum wage at the federal $7.25 floor since 2009, making it one of the longest-standing non-increases of any state that has a workforce. There are no local income taxes, no state paid family leave, and no state disability insurance. Compared to neighboring Illinois or Michigan, Wisconsin's payroll compliance load is lighter.

Wisconsin Payroll Obligations at a Glance

State Unemployment Insurance (SUI)

Wisconsin's SUI program is administered by the Wisconsin Department of Workforce Development (DWD). SUI is an employer-paid tax. Wisconsin employees do not contribute to state unemployment insurance.

SUI Rates for 2026

• New employer rate: 3.05% until an experience rating is established
• Experienced employer range: 0% to 12%, assigned annually by DWD
• Taxable wage base: $14,000 per employee per calendar year
• Maximum annual SUI cost per employee (at 12%): $1,680
• New employer annual cost per employee (at 3.05%): $427

Wisconsin's maximum SUI rate of 12% is one of the highest rate ceilings in the country. Employers with high turnover and significant layoff history face a steep potential liability. The 0% floor for experienced employers with outstanding claims histories means some established employers pay no SUI at all, but most employers fall somewhere between 0.5% and 5%.

DWD uses a reserve ratio experience rating system. The reserve ratio is your account's accumulated balance divided by your average taxable payroll. A strong positive balance earns lower rates over time. Employers receive annual rate notices from DWD before January 1.

FUTA Credit and Wisconsin SUI

Wisconsin employers who pay SUI on time receive the standard 5.4% FUTA credit, reducing the effective FUTA rate to 0.6% on the first $7,000 per employee. Wisconsin has maintained a solvent trust fund, avoiding FUTA credit reductions in recent years. Verify the annual credit status with the IRS FUTA list each November.

State Income Tax: Graduated Brackets

Wisconsin uses a four-bracket graduated income tax. The top rate of 7.65% applies to income over $304,170 (single filers) in 2026. This is a relatively high top rate for a Midwestern state. Wisconsin's brackets are inflation-indexed and adjust annually.

Wisconsin Income Tax Brackets (2026, Single Filers)

The wide middle bracket (3.54% to 5.3% between roughly $27,600 and $304,000) means most Wisconsin middle-income employees have most of their wages taxed at 5.3%. Only very high earners see a material portion of their wages in the 7.65% bracket. Verify current-year bracket thresholds from the Wisconsin Department of Revenue before the first payroll of each calendar year, as thresholds adjust for inflation.

Withholding Mechanics and Form WT-4

Wisconsin's employee withholding form is Form WT-4 (Employee's Wisconsin Withholding Exemption Certificate and New Hire Reporting). New employees complete a WT-4 at hire. Note that Wisconsin's WT-4 doubles as new hire reporting — employers submit the form to DWD as part of their new hire reporting obligation.

• Filing status: Single, married, or head of household
• Exemptions: Reduce the annual taxable income subject to withholding
• Additional withholding: Employees may elect a flat additional dollar amount per period
• Exemption from withholding: Available only when the employee had no WI tax liability in the prior year and expects none in the current year

If an employee does not submit a WT-4, withhold as if single with zero exemptions. The WT-4 can serve as new hire reporting when submitted to DWD by the employer, but electronic new hire reporting through DWD's system is also available and often more efficient.

No Local Income Taxes in Wisconsin

Wisconsin municipalities and counties cannot levy local income taxes. Employers maintain a single state withholding account for all Wisconsin employees regardless of work location. No local withholding registrations are required.

Minimum Wage in Wisconsin 2026

Wisconsin's minimum wage is $7.25 per hour, matching the federal minimum. Wisconsin law ties the state minimum wage to the federal rate, and the state has not enacted any increase above the federal floor since 2009. There is no automatic indexing mechanism, so any Wisconsin minimum wage increase requires a separate legislative act.

Wisconsin's $7.25 rate is among the lowest minimum wages in the country for states with formal minimum wage laws. Neighboring Minnesota has a $10.85+ minimum, Illinois has $15, and Michigan has $10.33. Employers operating in multiple states who expand to Wisconsin will find the labor cost floor dramatically lower.

Tipped Employees

Wisconsin allows a lower cash wage for tipped employees. Under Wisconsin administrative code DWD 272.03, tipped employees may receive as little as $2.33 per hour in direct wages provided tips bring total hourly compensation to at least $7.25. If tips are insufficient, the employer must make up the difference. Employers must notify employees of the tip credit and maintain records of tipped wages and tips received.

Opportunity Wage for Youth

Federal rules allow an opportunity wage of $4.25 per hour for workers under 20 during the first 90 consecutive calendar days of employment. After 90 days, the full $7.25 applies. Wisconsin follows this federal provision.

Overtime Rules

Wisconsin follows federal FLSA overtime standards plus Wisconsin's own overtime provisions. Under Wisconsin's overtime law (Wis. Stat. § 103.02), non-exempt employees must be paid at least 1.5 times the regular rate for hours over 40 in a workweek. This mirrors the FLSA and does not add daily overtime requirements. Wisconsin's exempt salary threshold follows the federal $684/week FLSA minimum.

Pay Frequency and Final Paycheck Rules

Pay Frequency

Wisconsin Statute § 109.03 requires employers to pay wages at least monthly, but most employers pay more frequently. In practice, DWD interprets "regular intervals" to mean at least monthly for salaried employees and more frequently for hourly workers by convention. Most Wisconsin employers pay bi-weekly or semi-monthly without issue.

Final Paycheck Rule

Wisconsin requires that a departing employee's final wages be paid no later than the next regular payday following the last day of employment. This applies to both voluntary resignations and employer-initiated terminations.

Wisconsin Family and Medical Leave Act (WFMLA)

Wisconsin has its own Family and Medical Leave Act (Wis. Stat. § 103.10) that operates alongside the federal FMLA. The Wisconsin FMLA applies to employers with 50 or more permanent employees and provides leave rights that differ from the federal law in important ways.

WFMLA Leave Entitlements

The Wisconsin FMLA provides less total leave than the federal FMLA in most categories. When both laws apply (employer has 50+ employees and employee is eligible), the employer must comply with the more protective standard. Because federal FMLA provides more total leave in most categories, federal FMLA generally governs the maximum leave entitlement. However, the Wisconsin FMLA covers certain circumstances or definitions that differ from federal law, so employers must analyze each leave request under both laws.

WFMLA Eligibility

• Employer coverage: 50 or more permanent employees (not counting temporary workers in the 50-employee threshold, which differs from federal FMLA's 75-mile radius test)
• Employee eligibility: Employed by the employer for at least 52 consecutive weeks and worked at least 1,000 hours during the preceding 52-week period

Both laws require leave to be unpaid unless the employer's policy allows or requires concurrent use of accrued paid leave. Job protection — restoration to the same or equivalent position — is required under both laws.

No State Paid Family Leave

Wisconsin's FMLA provides only unpaid leave. Wisconsin has no state paid family leave program and no state disability insurance fund. There are no Wisconsin payroll deductions for PFL or SDI.

New Hire Reporting

Wisconsin uses a combined system where Form WT-4 can serve as new hire reporting. Employers must report new hires within 20 days of the employee's first day of work. Reports can be submitted by filing WT-4 with DWD, by electronic reporting at dwd.wisconsin.gov, or by mail. Employers submitting 25 or more new hire reports per month must file electronically.

What are Wisconsin's income tax brackets in 2026?

Wisconsin has four brackets: 3.54% (first $13,810) to 7.65% (over $304,170) for single filers. Most employees pay at the 5.3% rate on the bulk of their wages. Bracket thresholds adjust annually for inflation — confirm current thresholds from the Wisconsin DOR before the first payroll of each year.

What is the Wisconsin FMLA?

The Wisconsin Family and Medical Leave Act (Wis. Stat. § 103.10) applies to employers with 50 or more permanent employees. It provides 6 weeks of unpaid parental leave and 2 weeks of medical leave per year. The leave runs concurrently with federal FMLA. Wisconsin FMLA provides less total leave than federal FMLA in most categories, but the eligibility rules and definitions differ in ways that require analysis case by case.

When must Wisconsin employers issue a final paycheck?

By the next regular payday following the last day of work. Willful withholding of wages can trigger a 50% penalty on top of the unpaid amount under Wisconsin wage claim statutes. Document the date of final payment with your payroll records.

Does Wisconsin have paid family leave?

No. The Wisconsin FMLA provides only unpaid leave. Wisconsin has no state PFL or SDI program. No Wisconsin payroll deductions for paid family leave are required.
