What is payroll compliance?

Payroll compliance means following all the federal, state, and local laws that control how you pay your employees. This includes classifying workers, calculating pay, withholding taxes, and keeping accurate records.

When you stay on top of compliance, you protect your business and make sure your team is paid correctly and on time.

Key payroll compliance laws you need to know

Payroll laws can be complex, but you can start by learning the basics. A few key federal laws form the foundation of payroll compliance in the US.

• Fair Labor Standards Act (FLSA): sets rules for minimum wage, overtime pay, and record-keeping, and defines exempt and non-exempt employees
• Federal Insurance Contributions Act (FICA): requires you to withhold Social Security and Medicare taxes from your employees’ paychecks and pay a matching employer portion
• Federal Unemployment Tax Act (FUTA): funds unemployment benefits for workers who have lost their jobs; you pay this tax based on your employees’ wages

You also need to follow state and local rules. These can include different minimum wage rates, paid sick leave laws, and state income taxes.

Payroll tax compliance essentials

You need to calculate, withhold, and pay the right payroll taxes to the right government agencies on time.

Your main responsibilities include withholding federal income tax, Social Security, and Medicare from each employee’s pay. Social Security tax has a wage base limit ($176,100 for 2025).

This is the maximum wage subject to that tax for the year. You also need to pay your own share of employer taxes, like Federal Insurance Contributions Act (FICA) and Federal Unemployment Tax Act (FUTA). State and local taxes also apply, and these vary depending on where your business operates.

Keeping organized records and meeting deposit deadlines is crucial. If you fall behind on payroll taxes, you could face significant penalties. Unpaid payroll tax debt has reached billions in major industries like construction and healthcare.

Start with the basics

Set up your new employee in your payroll system to prevent compliance issues and payment errors from day one.

Whether you use standalone payroll software or integrated accounting software, these essential steps ensure compliance:

• verify employment status: confirm they’re an employee, not an independent contractor – different rules apply to each
• collect accurate personal information: gather details from their completed W-4 form, including address, marital status, and tax withholding preferences
• enter correct compensation details: input salary, hourly rates, and any contractual bonuses or benefits for accurate tax calculations
• set proper work schedule: specify full-time, part-time, or flexible hours to ensure correct overtime and benefit calculations
• confirm banking information: verify account details in writing to prevent misdirected payments and costly corrections
• align start and pay dates: set their system start date and ensure pay periods match your existing schedule

Enroll your new employee

In some countries, you must enroll new employees in your pension or retirement plan.

In other countries it’s optional, but many employers do it anyway. It can be a tax-efficient way to make your business more appealing to potential job applicants.

Pension or retirement plan contributions can be complex. The amount you and your employee contribute may vary based on age, seniority, and salary. Getting it right helps you avoid issues in the future.

Government websites provide clear guidance. Check them first to understand what you need to do to run your own plan properly.

Common payroll compliance mistakes to avoid

You can make payroll compliance mistakes if you overlook industry-specific requirements or unique business situations. Here are the most frequent issues and how to avoid them:

High employee turnover

Hiring frequently increases the chance of setup errors and missed termination requirements.

• Solution: Create standardized checklists for onboarding and offboarding to ensure consistency

Expense reimbursement errors

Handling travel, meals, or entertainment expenses incorrectly can trigger tax violations.

• Solution: Review IRS guidelines for your industry and establish clear expense policies

Cash payment complications

Paying employees in cash requires extra documentation and security measures.

• Solution: Maintain detailed records and consider transitioning to electronic payments for better tracking

Overtime calculation mistakes

Incorrect overtime rates, especially for weekend or holiday work, lead to wage violations. For example, specific rules for Call-back overtime work require employees to be paid a minimum of 2 hours of overtime, regardless of the actual time worked.

• Solution: Understand your state’s overtime laws and use software that automatically calculates rates

Multi-location compliance gaps

Operating in different states or localities means you must follow different minimum wage, tax, and leave requirements.

• Solution: Research local laws for each location and update your systems accordingly

Consider outsourcing payroll

Payroll outsourcing transfers payroll processing to specialized companies while you retain legal responsibility for compliance. Many businesses with up to 50 employees choose this option to reduce administrative burden.

Benefits of outsourcing payroll

• Time savings: You eliminate weekly payroll processing tasks
• Compliance expertise: Professional providers stay current with changing regulations
• Reduced overhead: You do not need dedicated payroll staff or software
• Error reduction: Specialists handle complex calculations and filings

Important considerations

• Data accuracy responsibility: You must provide correct employee information
• Reduced control: You have less direct oversight of payroll processing
• Legal liability: You remain legally responsible for compliance, even with outsourcing
• Communication delays: Changes may take longer to implement through a third party

Consider your business needs, budget, and how much control you want before you decide.

Use payroll software that helps you

automates compliance tasks, reduces errors, and saves time when you handle payroll in-house. Choose software with these essential features:

• User-friendly interface: You can reduce training time and minimize mistakes with an intuitive design
• Local compliance features: Built-in tax tables and forms help you meet your state and local requirements
• Accounting integration: Seamless connection eliminates duplicate data entry and sync errors
• : Online access gives you real-time updates, automatic backups, and remote capabilities
• Automated calculations: The software handles complex overtime, benefits, and tax calculations accurately
• Reporting capabilities: The software generates required government forms and internal reports automatically

Read customer reviews and ask for demos to make sure the software fits your business needs and technical skills.

Talk to your new employee

When your new hire starts, talk to them about the basics. Introduce them to colleagues, discuss health and safety, and show them around the office.

Also, talk to your new employee about their compliance responsibilities. These include:

• tell you if their personal situation changes (such as address or marital status)
• keep all receipts for allowable business expenses and travel costs
• record any overtime they work
• meet any obligations in their employment contract with you

Simplify payroll compliance and focus on growth

Payroll compliance protects your business while creating efficient processes that save time and money long-term. When you get compliance right from day one, you avoid costly penalties and build systems that scale with your business.
