Written by Sheila Welch | Oct 08, 2025

Hiring part-time or seasonal help can keep your business running during busy times. But the payroll process often gets harder, not easier. More workers mean more rules to follow, more pay schedules to manage, and more chances for something to go wrong.

If you have ever searched for last-minute answers about benefits, wage laws, or classification rules, you are not alone. Managing payroll for a changing team can get messy fast but it doesn’t have to. With a few simple strategies, you can stay compliant, pay your people correctly, and keep your focus where it belongs: on running your business.

Seasonal vs Part-Time 

It is easy to confuse these roles, but the distinction matters. 

Seasonal employees work for a limited time during peak business periods. These roles might include holiday rush, summer break, or a special event. 

Part-time employees work fewer hours than full-time staff. Their roles continue beyond one season and meet ongoing business needs. 

The difference between these two affects how you handle payroll, benefits, and legal requirements. Mislabeling an employee can cause tax issues, penalties, and employee complaints. Make sure every role is clearly defined and documented from the beginning. 

Minimum Wage Rules 

Federal law sets a minimum wage, but many states and cities have their own higher rates. You must pay employees the highest wage that applies to the location where they actually work. 

If your staff works in more than one place, you may need to follow more than one rule. These rules can also change during the year. 

Payroll software that tracks minimum wage laws by location can help avoid mistakes. If you handle it yourself, review the current wage rates at least every quarter. 

Benefits and the ACA 

The Affordable Care Act can be confusing, but the basics are clear. 

Most businesses with fewer than 50 full-time equivalent employees are not required to provide health insurance. Seasonal employees who work 120 days or fewer in a year do not count toward your full-time equivalent total. 

To calculate your full-time equivalent count, add all full-time staff and combine total part-time hours for the month, then divide by 120. If the total reaches 50, your benefit obligations may change. 

Set clear policies and communicate them up front. Your employees should know what benefits are offered from the start. 

Payroll Frequency 

You cannot pay employees whenever it is convenient. Most states require that employees be paid on a regular schedule, whether weekly, biweekly, or monthly. Rules may vary depending on where your employees work. Different pay schedules might be required for different team members. 

Missing a scheduled payday or applying the wrong schedule can lead to penalties and employee frustration. Choose a payroll schedule you can maintain and use tools that support flexible pay frequencies. 

Busy Season Tips to Keep Payroll on Track 

During peak seasons, payroll errors become more likely. Some common mistakes include: 

  • Forgetting to add new hires before payroll runs 
  • Losing track of onboarding paperwork 
  • Missing payroll deadlines when things get hectic 

Use digital onboarding to collect tax forms and direct deposit information. If you are hiring a large team, consider a staffing agency that handles payroll. Train key staff members to support onboarding during high-volume periods. 

A reliable payroll system should adjust easily as your team grows or shrinks. 

Track Every Hour 

Accurate time tracking is not just helpful. It is required by law. It ensures compliance with wage laws, overtime pay, and Affordable Care Act calculations. Inaccurate tracking can lead to penalties, missed payments, or employee disputes. 

Use digital systems, time tracking apps, or clock-in tools to record hours worked. Review records regularly and make sure employees understand how to clock in and out correctly. Define what counts as paid time and how breaks are managed. Clear expectations reduce confusion. 

Stay Ahead of Payroll Changes 

Payroll laws change often. Common issues include: 

  • Sudden increases in minimum wage 
  • Confusion caused by new hires and turnover 
  • Missed deadlines or outdated forms 

To stay current, check your state labor department's website regularly. Use payroll tools that track legal changes automatically. If you are unsure, speak with a payroll expert instead of making assumptions. 

The Bottom Line 

Running payroll for seasonal and part-time employees does not need to be overwhelming. With the right approach, you can meet all legal requirements, pay your people accurately, and avoid costly mistakes. 

Use clear job classifications, track hours carefully, and follow a consistent payroll schedule. When in doubt, get help from a professional. 

If your payroll feels chaotic, now is the time to fix it. Solid systems and a clear process make payroll easier for everyone.
