State Unemployment Insurance Quarterly Wage Reports
Every employer must file a quarterly wage report with the unemployment insurance agency in each state where it has covered employees, listing every employee by name and Social Security number along with wages paid that quarter.
The requirement is federal - federal law has required states to collect quarterly wage reports from employers since 30 September 1988 - but everything about how you comply is state-specific: the form, the deadline, the taxable wage base, the filing method and the penalties.
What gets reported?
Two layers on most state forms:
Employer level - total wages paid to covered workers, excess wages, taxable wages, and tax due.
Employee level - each employee's name, Social Security number, and total wages paid during the quarter.
When is it due?
Most states use the last day of the month following the end of the quarter, with the deadline rolling to the next business day when that falls on a weekend or holiday:
| Quarter | Typically due |
|---|---|
| Jan-Mar | April 30 |
| Apr-Jun | July 31 |
| Jul-Sep | October 31 |
| Oct-Dec | January 31 |
This is verified for Florida and Texas and is the common pattern - but treat it as "most states" and confirm each one you file in. There is no federal deadline that overrides state law here.
The taxable wage base varies enormously
This is the number that surprises people, and it makes multi-state payroll harder than it looks. Effective January 2026, the wages subject to state unemployment tax range from:
| State | Taxable wage base |
|---|---|
| California, Florida, Tennessee | $7,000 |
| Arizona | $8,000 |
| Texas | $9,000 |
| New York | $17,600 |
| Hawaii | $64,500 |
| Washington | $78,200 |
(Source: U.S. Department of Labor, Significant Provisions of State UI Laws, January 2026.)
An employee earning $80,000 generates unemployment tax on $7,000 of wages in California and on $78,200 in Washington - an eleven-fold difference on the same salary. Several states also index the base annually, so it moves.
Which state does a multi-state employee belong to?
You report each employee to one state, and there's a four-part test applied in order. You don't get to pick, and you don't split.
1. Localisation of service. Service is localised in a state if it's performed entirely within that state, or performed both inside and outside where the outside work is incidental to the work inside. If this resolves it, stop here.
2. Base of operations. The fixed place of a more or less permanent nature from which the employee starts work and to which they customarily return for instructions, communications or supplies.
3. Place of direction or control. Where the basic authority exists and from which general control emanates - not where a supervisor happens to sit, but where the operational authority lives.
4. Residence. Reached only when the service isn't localised anywhere and none of the tests above resolves it.
Where none applies, election provisions and interstate reciprocal coverage arrangements let an employer elect to cover all of an individual's service in one state.
The practical point: remote and travelling employees are the hard cases, and "wherever they live" is the last test, not the first. A remote employee working from home in one state but attached to an operational base in another may well be reportable to the base state.
SUTA dumping
Federal law requires every state to prohibit two schemes designed to obtain a lower unemployment tax rate:
- Transferring payroll to a shell or low-rate entity
- Acquiring a business primarily to obtain its favourable rate
The rules that follow are worth knowing because they're mandatory, not elective:
- Unemployment experience must be transferred whenever there is substantially common ownership, management or control between two employers. This isn't a choice.
- Where a non-employer acquires a business solely or primarily to obtain lower contribution rates, experience is not transferred and a new-employer or standard rate is assigned instead.
- States must impose meaningful civil and criminal penalties. For employers, that's either the state's maximum rate or a penalty of at least 2% of taxable wages for the violation year plus the three following years. Advisors who promote these schemes face their own fines.
Reorganisations, acquisitions and entity consolidations all touch this, and the transfer rule applies whether or not anyone intended a tax outcome.
What are the penalties?
State-specific. Florida illustrates the structure:
- $25 for each 30 days or fraction the report is delinquent
- $50 or 10% of tax due, whichever is greater, up to $300 per report, for erroneous or incomplete reports
- $25 per report plus $1 per employee, up to $300, for failing to file electronically when required
Electronic filing mandates are common and threshold-based - Florida requires it at 10 or more employees in any quarter of the preceding state fiscal year; Texas requires it of all employers, with hardship waivers.
Common data problems
Social Security number validation. States apply hard rules - numbers cannot begin with 9, cannot start with 000 or 666, cannot have 00 in the middle two digits, and cannot end in 0000. A single malformed SSN can reject an entire file.
Employees reported to the wrong state, usually because the system defaults to home address rather than applying the four-factor test.
Wage base tracking across states, particularly for an employee who transfers mid-year.
Reconciling to federal filings. Your quarterly state wage totals and your federal employment tax returns describe the same payroll and should be explicable against each other.
Frequently asked questions
Do we file in every state where we have one employee?
Generally yes - one covered employee in a state creates a filing obligation there.
Can we report an employee to two states?
No. The four-factor test assigns each employee to one state.
What if an employee moves mid-year?
The test is reapplied. Wage base tracking gets complicated, since the new state starts its own count.
Is the deadline the same everywhere?
Most states use the last day of the month after quarter end, but confirm each state - there's no federal override.
Do we have to file electronically?
Increasingly yes, on state-specific thresholds, with penalties for filing on paper when you're required to file electronically.
What is SUTA dumping?
Restructuring to obtain a lower unemployment tax rate. Experience transfer is mandatory between commonly-owned employers, and penalties run to at least 2% of taxable wages for four years.
