To hire seasonal employees legally, you need to classify each worker correctly, complete Form I-9 and Form W-4 on federal deadlines, report the hire to your state within 20 days, pay at least the applicable minimum wage with overtime where required, and meet the same tax, workers’ compensation, and workplace safety obligations you would for permanent staff. A short season does not shrink the compliance list. It just compresses the timeline.
Classify Each Worker Before Anything Else
Every seasonal hire is either an employee or an independent contractor, and the label on your paperwork doesn’t decide it. The IRS looks at who controls how, when, and where the work gets done. If you set the schedule, supply the equipment, and direct the tasks, the worker is your employee.
Misclassifying an employee as an independent contractor is expensive. If you filed the required 1099 forms for the misclassified worker, you owe 1.5% of wages for federal income tax withholding plus 20% of the employee’s share of Social Security and Medicare taxes. Skip the 1099s too, and those rates double to 3% and 40%.1Office of the Law Revision Counsel. 26 U.S. Code 3509 – Determination of Employer’s Liability for Certain Employment Taxes The full employer share of FICA still sits on top, with interest. The Department of Labor can add liability for any unpaid minimum wage or overtime the worker should have received.
Paperwork Before the First Day
Three documents drive early compliance: Form I-9, Form W-4, and your state’s new-hire report. Each has its own deadline, and each triggers penalties when missed.
Form I-9
Every employee must complete Section 1 of Form I-9 no later than their first day of work. You then have three business days after that first day to examine the worker’s original identity and employment authorization documents and complete Section 2. If the job will last fewer than three business days, the entire form has to be finished on day one.2U.S. Citizenship and Immigration Services. Instructions for Form I-9, Employment Eligibility Verification You must physically examine original documents; photocopies aren’t acceptable.
Form W-4
Each seasonal worker fills out a W-4 so you can withhold the correct federal income tax from their pay.3Internal Revenue Service. About Form W-4, Employee’s Withholding Certificate Get it done before the first pay period. If a worker doesn’t submit one, you’re required to withhold as if they claimed single filing status with no adjustments, which produces the highest withholding rate.
New Hire Reporting
Federal law requires you to report every new hire to your state’s Directory of New Hires within 20 days of the start date. The report includes the employee’s name, address, Social Security number, and start date, along with your business name, address, and EIN. The system feeds federal child-support enforcement and unemployment insurance fraud detection. Penalties for failing to report range from $25 per missed report up to $500 if the failure results from a conspiracy between employer and employee.4Office of the Law Revision Counsel. 42 USC 653a – State Directory of New Hires Some states impose shorter deadlines than the federal 20-day window, so check yours.
E-Verify Where It Applies
Federal contractors with covered contracts must use E-Verify to electronically confirm each new hire’s employment eligibility.5E-Verify. Federal Contractors Several states also require E-Verify for all employers or for those above a certain size. Where it’s voluntary, it still adds a layer of protection against unknowing employment of unauthorized workers.
Wages and Overtime
The federal minimum wage of $7.25 per hour applies to seasonal workers the same way it applies to permanent staff. Most states set a higher floor, and you pay whichever rate is greater. Workers under 20 can be paid a reduced rate of $4.25 per hour during their first 90 consecutive calendar days with your business, as long as their employment does not displace other workers. Once the 90 days pass or the worker turns 20, whichever comes first, the full minimum wage applies.6U.S. Department of Labor. Fact Sheet #32: Youth Minimum Wage – Fair Labor Standards Act
Most seasonal employees are entitled to overtime at 1.5 times their regular rate for hours over 40 in a workweek. Two categories of seasonal employers may qualify for exemptions.
Amusement and Recreational Establishments
Amusement parks, recreational establishments, organized camps, and nonprofit educational conference centers are exempt from both minimum wage and overtime requirements if the business either operates no more than seven months in a calendar year, or earns at least two-thirds of its annual revenue in a six-month peak season.7Office of the Law Revision Counsel. 29 USC 213 – Exemptions The exemption does not apply to private businesses operating under contract inside national parks, national forests, or wildlife refuges.
Agricultural Employers
Workers employed in agriculture are exempt from overtime entirely, regardless of hours worked. Farms that used fewer than 500 “man days” of agricultural labor in any quarter of the preceding year are also exempt from minimum wage and overtime for the following year. A man day counts as any day a worker performs at least one hour of farm labor.7Office of the Law Revision Counsel. 29 USC 213 – Exemptions Additional exemptions cover immediate family members, certain hand-harvest laborers paid on a piece-rate basis, and workers engaged primarily in range livestock production.8U.S. Department of Labor. Fact Sheet #12: Agricultural Employment Under the Fair Labor Standards Act
Hiring Minors
Hiring minors triggers a distinct set of federal rules under 29 C.F.R. Part 570. The general minimum age for non-agricultural employment is 16, though 14- and 15-year-olds may work in approved non-hazardous occupations. Workers under 18 are barred from jobs the Department of Labor has declared hazardous, including operating power-driven equipment and most manufacturing work.9eCFR. 29 CFR Part 570 – Child Labor Regulations, Orders and Statements of Interpretation
For 14- and 15-year-olds, hour limits are strict: no more than 3 hours on a school day, no more than 18 hours in a school week, and no more than 8 hours on a non-school day. During summer and other periods when school is out, the weekly cap rises to 40 hours. Violating these standards carries civil penalties of up to $16,035 per affected worker, and the amount climbs significantly when a violation causes serious injury or death.9eCFR. 29 CFR Part 570 – Child Labor Regulations, Orders and Statements of Interpretation
Get documentary proof of age before a minor starts work. A birth certificate is the preferred document, though a signed statement from a registrar of vital statistics also works. Having an age certificate on file protects you from liability if an underage worker misrepresents their age.
Payroll Taxes You Owe on Seasonal Wages
Beyond withholding federal income tax based on the W-4, you owe federal unemployment tax (FUTA) on the first $7,000 of wages paid to each seasonal employee during the calendar year. The statutory FUTA rate is 6.0%, but employers who pay their state unemployment taxes on time receive a credit of up to 5.4%, reducing the effective federal rate to 0.6%.10Internal Revenue Service. Topic No. 759, Form 940 – Employer’s Annual Federal Unemployment (FUTA) Tax Return You also owe the employer share of Social Security tax (6.2% on wages up to the annual cap) and Medicare tax (1.45% on all wages) for every seasonal employee.
State unemployment insurance taxes apply on top of FUTA. Rates vary by industry, claims history, and the state where the work is performed. Because seasonal workers frequently file claims when their positions end, a high volume of short-term hires can push your state unemployment rate up over the following years. Budget for it as a real cost of seasonal staffing.
Health Coverage: When Seasonal Hires Trigger the ACA
The Affordable Care Act’s employer mandate applies to businesses that averaged at least 50 full-time employees (including full-time equivalents) in the prior calendar year. There is a built-in seasonal exception: if your workforce only exceeds 50 employees for 120 days or fewer during the year, and the workers pushing you over that line are seasonal, you are not an applicable large employer.11Internal Revenue Service. Determining if an Employer Is an Applicable Large Employer
If you do qualify as an applicable large employer, determine whether your seasonal workers are full-time for ACA purposes, meaning they average at least 30 hours per week. For workers with unpredictable schedules, the IRS allows a look-back measurement method: track hours over a measurement period of 3 to 12 months, and if the worker averaged 30 or more hours per week, you must offer health coverage during a subsequent stability period of at least six months. Missing these obligations triggers penalties of $3,340 per full-time employee (minus the first 30) if you fail to offer coverage at all, or $5,010 per employee who receives a marketplace subsidy if the coverage you offer is unaffordable or inadequate.12Internal Revenue Service. Types of Employer Payments and How They’re Calculated
Workers’ Compensation and OSHA
Nearly every state requires employers to carry workers’ compensation insurance for all employees, including seasonal and temporary staff. A six-week tenure does not reduce the obligation. Premiums are calculated as a rate per $100 of payroll and vary by job classification, so a seasonal retail cashier costs far less to insure than a seasonal tree trimmer. Agricultural and migrant worker operations face additional state-specific rules, with some states exempting small farms and others requiring coverage for any hired labor.
Federal OSHA requirements apply to seasonal workers with the same force as permanent staff. If you hire through a staffing agency, both you and the agency are considered joint employers and share responsibility for a safe work environment. In practice, the staffing agency typically handles general safety orientation while you, as the host employer, provide training specific to your equipment and workplace hazards.13Occupational Safety and Health Administration. Protecting Temporary Workers OSHA can cite both the agency and the host employer for violations, including inadequate training. Short duration doesn’t reduce your training obligation; workers unfamiliar with your site are more likely to get hurt.
Rehiring the Same Workers Next Season
If you rehire someone within three years of the date their original Form I-9 was completed, you can use Supplement B of the existing form instead of starting over. Confirm the original I-9 still relates to the worker and check whether their employment authorization documents have expired. If the documents remain valid, record the rehire date in Supplement B. If they’ve expired, the worker must present a current List A or List C document for reverification.14U.S. Citizenship and Immigration Services. Completing Supplement B, Reverification and Rehires
USCIS also recognizes seasonal employment as “continuing employment,” which means the worker’s I-9 remains in effect during the off-season even if no work is performed.15U.S. Citizenship and Immigration Services. Handbook for Employers M-274, Section 8.0 – Rules for Continuing Employment and Other Special Rules If you treat the worker as never having been terminated, you don’t need to update the I-9 when they return. If you formally terminated them, the Supplement B process applies.
Foreign Seasonal Labor: H-2A and H-2B
Agricultural employers who cannot find enough domestic workers may petition for foreign seasonal labor through the H-2A visa program. The process requires a Temporary Labor Certification from the Department of Labor, which involves demonstrating that you actively recruited U.S. workers and that hiring foreign workers will not depress wages or working conditions for domestic employees. H-2A employers must pay at least the highest of the adverse effect wage rate, the prevailing wage, or the applicable minimum wage.16U.S. Department of Labor. Fact Sheet #26: Section H-2A of the Immigration and Nationality Act You must also provide free housing that meets federal standards, offer transportation between the worker’s home country and the job site, and guarantee employment for at least 75% of the workdays in the contract period. If you fall short of that guarantee, you owe the worker what they would have earned. You must continue to hire any qualified U.S. worker who applies until at least 50% of the contract period has passed.
Non-agricultural employers in industries like hospitality, landscaping, and seafood processing use the H-2B program. The statutory cap is 66,000 visas per fiscal year, split evenly between the first and second halves. For FY 2026, the Department of Homeland Security authorized an additional 64,716 supplemental visas.17Federal Register. Exercise of Time-Limited Authority To Increase the Fiscal Year 2026 Numerical Limitation for the H-2B Temporary Nonagricultural Worker Program Like H-2A, the H-2B process starts with a Temporary Labor Certification and then a Form I-129 petition filed with USCIS. Supplemental-cap petitioners must submit an attestation under penalty of perjury that the business will suffer irreparable harm without the requested workers, and most supplemental visas are limited to returning workers who held H-2B status in one of the three prior fiscal years.
Final Paychecks and Record Retention
When a seasonal position ends, federal law does not require you to deliver the final paycheck immediately. Timing depends on your state, and many states impose deadlines ranging from the last day of work to the next regular payday.18U.S. Department of Labor. Last Paycheck Missing your state’s final-pay deadline can trigger waiting-time penalties, so look up the rule before your seasonal wind-down.
Keep I-9 forms for three years from the date of hire or one year after employment ends, whichever is later.19U.S. Citizenship and Immigration Services. I-9, Employment Eligibility Verification Preserve payroll records including wage rates, hours worked, and deductions for at least three years, and keep supporting documents like time cards and work schedules for two years.20U.S. Department of Labor. Fact Sheet #21: Recordkeeping Requirements Under the Fair Labor Standards Act Store them where you can produce them quickly if an agency requests an inspection.
