Running payroll is more than just cutting paychecks. It's about following the rules—a lot of them. In 2024, the IRS assessed over $84.1 billion in civil penalties, including $20.9 billion against businesses. Many of which stem from common business violations, such as late filings, withholding errors, and reporting failures.
That's where payroll compliance comes in. Whether you're expanding globally or managing teams across borders, understanding compliance is essential. In this blog, we'll break down what payroll legal compliance means, why it matters, and walk you through 8 key rules every business must follow.
What Is Payroll Compliance?
Payroll compliance is the process of making sure you follow all the laws and regulations around paying your employees. These include federal, state, and local tax rules, labor laws, employee classifications, and wage requirements. Your company must follow these rules—or risk penalties, audits, and lawsuits.
Compliance with payroll is essential if you work with international teams. Global payroll compliance involves navigating multiple layers of regulations, depending on the country, which can be challenging to manage without expert assistance.
How Global Payroll Compliance Works
International compliance in payroll involves adhering to labor laws, tax rules, and payment regulations in every country where you employ workers. Here are some key differences by country:
UK: Must follow Employment Rights Act for contracts, redundancy, parental leave.
UAE: Businesses must pay via the Wages Protection System (WPS) through approved banks.
China: Labor Law dictates contracts, wages, benefits, and working hours.
Japan: The Labor Standards Act sets strict rules on wages, overtime, and holidays.
If you're not local, you're likely to miss something. That's where international Employer of Record (EOR) providers like Atlas come in. Our team of local experts know the rules, and we take on the legal responsibility for compliance.
8 Payroll Rules Every Business Must Follow
To stay compliant and avoid costly errors, every business should follow these eight essential payroll rules.
1. Classify Workers Correctly
One of the biggest payroll mistakes businesses make is misclassifying workers. Are they employees or independent contractors? Getting this wrong affects taxes, benefits, and legal protections. It could also lead to huge fines and back pay if audited.
Use IRS guidelines, or in international cases, follow local laws. Better yet, lean on international EOR providers like Atlas, who can help classify workers correctly in every country.
2. Follow Local, National, and Regional Tax Laws
Payroll taxes can be complex, no matter where your business operates. Each country has its own rules for tax withholding, employer contributions, and filing deadlines. You are responsible for understanding and following the specific tax laws that apply to every employee's work location.
In the United States, for example, you must:
Withhold federal income tax (based on IRS Form W-4)
Withhold and match FICA taxes (Social Security and Medicare)
Pay FUTA (federal unemployment tax)
Handle state and, in some cases, local income taxes
Internationally, requirements vary:
Canada: Employers must deduct income tax, Canada Pension Plan (CPP), and Employment Insurance (EI) premiums.
United Kingdom: Employers are responsible for PAYE (Pay As You Earn) tax and National Insurance contributions.
Germany: Payroll must include income tax withholding, solidarity surcharge, church tax (if applicable), and social security.
Australia: Employers must handle PAYG (Pay As You Go) withholding and superannuation contributions.
Global payroll compliance services or EOR providers like Atlas can help you meet these requirements accurately and on time.
3. Comply with Minimum Wage and Overtime
Wage and hour laws differ widely across countries. To stay compliant, especially when managing global teams, employers must follow local regulations for minimum wage and overtime.
In the U.S., the Fair Labor Standards Act (FLSA) sets:
A federal minimum wage of $7.25/hour (many states set higher rates)
Overtime pay of 1.5x for hours over 40 per week
Other countries have their own frameworks:
UK: Minimum wage varies by age; overtime terms are set by contract.
Germany: Nationwide minimum wage and regulated work hours.
Australia: Industry-specific pay rates and overtime under the Fair Work Act.
UAE: No official minimum wage, but overtime pay is legally required.
China: Minimum wages vary by region; overtime rates range from 150% to 300%.
When using Atlas' EOR payroll services for global employees, applying the correct local rules is straightforward.
4. Honor Equal Pay Compliance
Equal pay compliance means ensuring employees are paid fairly—without discrimination—for doing comparable work under similar conditions. Equal pay laws are expanding worldwide to address wage gaps. Examples include:
UK: Gender pay gap reporting required for employers with 250+ staff.
Canada: Federally regulated employers must follow the Pay Equity Act.
EU: Enforcing pay transparency and equal pay through new directives.
Australia: Large employers must report gender equality metrics.
To ensure compliance:
Run pay equity audits regularly
Use benchmark data to guide salary decisions
Document all compensation changes
Avoid discriminatory or gender-based pay negotiations
5. Accurately Track Hours and Pay
Poor time tracking is a payroll disaster waiting to happen. Use tools that track:
Regular hours
Overtime
Paid leave
On-call and meal break penalties (in some states)
Atlas keeps you compliant and ensures employees are paid fairly and on time, no matter where they work.
6. Handle Garnishments and Deductions Properly
Employers are required to process wage garnishments for things like:
Child support
Unpaid taxes
Court-ordered debts
If you skip or delay these, your business could be held responsible. Use automated systems to manage deductions accurately. At Atlas HXM, we ensure garnishments and deductions are processed accurately and on time through automated, compliant payroll systems.
7. Stay Compliant with Leave Laws
Leave regulations differ by country, covering maternity, paternity, sick leave, and more. Many regions require continued benefits, statutory pay, or payroll deductions during leave.
For example:
Canada: Paid leave through Employment Insurance
UK: Statutory Maternity, Paternity, and Shared Parental Leave
Germany: Paid sick and parental leave under federal law
Australia: Unpaid parental leave and personal/carer's leave
Brazil: Paid maternity leave and health-related benefits
Atlas ensures you meet local leave laws without overwhelming your internal team.
8. Pay Employees on Time & Keep Accurate Payroll Records
Late paychecks break trust—and the law. Most states have strict rules about payroll frequency (weekly, bi-weekly, etc.) and final pay after termination. A missed or late payment can lead to wage claims or penalties.
Keep payroll records for at least 3 - 4 years, which include:
Employee data (name, address, SSN)
Hours worked
Pay rates
Tax filings
U.S. Payroll Laws You Need to Know
When it comes to payroll regulations adherence, several U.S. federal laws lay the foundation for how employers must operate. These include:
Fair Labor Standards Act (FLSA): Governs minimum wage, overtime pay, and recordkeeping.
Federal Insurance Contributions Act (FICA): Requires Social Security and Medicare tax withholding and matching.
Federal Unemployment Tax Act (FUTA): Employers must pay unemployment taxes to support jobless benefits.
Equal Pay Act (EPA): Requires equal pay for men and women performing similar jobs.
Understanding and applying these laws correctly is essential to remain compliant and avoid penalties.
Why Payroll and Compliance Go Hand-in-Hand
Payroll and compliance are two sides of the same coin. You can't have one without the other. If you're not complying with tax rules or labor laws, your payroll system is broken. When done right, labor law compliance ensures your employees get paid accurately, on time, and in line with legal requirements—no matter where they are in the world.
It's also key to staying audit-ready and avoiding costly fines. That's why many businesses today rely on compliance services and EOR solutions like Atlas HXM to handle the complex aspects of their operations.
Common Payroll Compliance Mistakes to Avoid
Even minor errors can lead to significant fines, back pay, or lawsuits. Here are the most common compliance mistakes businesses make:
Misclassifying workers (employee vs contractor)
Missing tax deadlines or underpaying taxes
Inaccurate payroll records or lost documentation
Failing to apply state-specific wage laws
Forgetting garnishments or withholding errors
Incorrect overtime pay calculations
Workers’ compensation misclassification
These errors can be costly, but most are avoidable with a consistent payroll process and a trusted EOR partner like Atlas.
EOR Payroll Compliance as Risk Mitigation
Compliance isn't just about following rules—it's a strategic layer of risk protection for your business.
When compliance fails, the consequences are severe:
Legal risk: Misclassification, tax errors, or missed filings can trigger audits, lawsuits, and government penalties.
Financial risk: Fines, back pay, and interest charges can add up quickly, mainly when operating in multiple countries.
Reputational risk: Delayed payments, wage disputes, or discrimination claims can damage employee trust and employer brand.
Businesses expanding globally are quickly turning to EOR providers like Atlas, which assumes full compliance liability.
The Role of EOR Payroll in Staying Compliant
Using EOR payroll means outsourcing your employment and compliance responsibilities to an EOR provider. They become the legal employer and handle everything from contracts to benefits to taxes.
Why it matters:
You avoid setting up a legal entity in each country
You minimize the risk of non-compliance
You save money and time on global expansion
If you're growing globally, an international EOR is the fastest and safest way to build a team.
