State Taxes

Tax Type	Applies In	2026 Notes

Federal Income Tax Withholding

International Payroll Rules

A uniform payroll strategy rarely works across international teams. Payroll compliance must be localized because labor laws, tax systems, benefits, and reporting requirements vary significantly by country.

• European Union - Working Time Directive (WTD): Limits working hours and requires minimum rest periods and paid leave across EU member states.
• China - Labor Law: Employers must manage strict overtime rules, social insurance contributions, and mandatory written employment contracts.
• UAE - Wages Protection System (WPS): Salaries must be paid through approved banking systems to remain compliant with labor regulations.
• United Kingdom - PAYE Reporting: Employers must report payroll information to HMRC in real time during each payroll cycle.
• Japan - Labor Standards Act: Payroll timing, overtime calculations, and payslip requirements are tightly regulated.
• Germany - Social Contribution Requirements: Payroll must include mandatory pension, healthcare, unemployment, and insurance contributions.
• France - Labour Code: Employers must follow detailed payslip standards and local collective bargaining agreements.
• Brazil - CLT Regulations: Payroll includes mandatory 13th-month salary payments and severance fund contributions.
• India - Labour Codes: Employers must manage tax withholding, social security requirements, and state-level payroll compliance.

International payroll compliance becomes significantly more complex once companies hire across multiple countries, which is why many global teams rely on payroll providers or employer-of-record (EOR) services to manage local requirements.

Pro Tip

Payroll compliance is no longer just an HR issue—it’s a board-level concern. When your workforce spans 10 or more countries, even a single late remittance or misclassification can trigger audits, fines, or reputational risk. We advise finance leaders to treat payroll compliance as a risk category—one with rising scrutiny and legal implications.—Katherine Loranger, CPO, Sa

Payroll Compliance Mistakes (And How To Avoid Them)

Most payroll compliance mistakes are preventable with the right systems, reviews, and workflows in place. Here are some of the most common issues employers run into, and how to avoid them:

Common Mistake	Why It’s Risky	How To Prevent It
Incorrect W-4 exemptions	Incorrect withholding can trigger IRS reviews or lock-in letters.	Review W-4 forms regularly and verify employee tax updates.
Misclassifying employees vs contractors	Misclassification can lead to back taxes, penalties, and unpaid benefits.	Reassess worker relationships regularly and use Form SS-8 when uncertain. Consider working with professional employer organizations or employer of record services for multi-state or global teams.
Equal pay violations	Unequal pay practices can result in EEOC complaints and lawsuits.	Conduct pay audits and document compensation decisions clearly.
Workers’ comp classification errors	Incorrect payroll classifications can create audit issues and back premiums.	Audit payroll records before annual insurance reviews.
Late payroll tax deposits	Missed filing deadlines can trigger penalties and interest charges.	Automate tax filings and payroll reminders where possible.
Poor payroll recordkeeping	Missing payroll records create problems during audits and employee disputes.	Store payroll records and filings in a centralized system.
Ignoring state and local law updates	Payroll rules vary significantly across jurisdictions and change frequently.	Review updates regularly through sources like the IRS, Department of Labor, and American Payroll Association.
Inconsistent payroll data	Mismatched HR, payroll, and time-tracking data can create reporting errors.	Standardize data entry and integrate payroll systems where possible.
Failing to track remote worker locations	Remote employees may create unexpected state tax and compliance obligations.	Regularly audit employee work locations and tax settings.
Overrelying on automation	Payroll software can still miss edge cases like bonuses or multi-state work.	Manually review high-risk payroll scenarios and consult state-specific HR consultancies when needed.
Waiting until year-end to review compliance	Payroll issues compound over time and become harder to correct later.	Run periodic payroll audits throughout the year.

Pro Tip

Never rush year-end processing. I block out 3x more time than I think I need. December’s always crazy with W-2 prep, bonus calculations, and benefit changes. Plus, there’s always some last-minute drama with employees wanting to adjust their withholdings.—Andrew Lokenauth, Fractional CFO and financial adviseC

Payroll Compliance FAQs

Who is responsible for payroll compliance?

Payroll compliance is typically shared across HR, payroll, finance, and leadership teams. While payroll departments, external providers, or global payroll vendors may handle day-to-day payroll processing, the employer remains ultimately responsible for payroll accuracy and legal compliance.

What are employee payroll classifications?

Payroll classifications determine how workers are paid and which labor laws apply to them. Common classifications include exempt employees, non-exempt employees, independent contractors, temporary workers, and part-time employees.

What’s the difference between exempt and non-exempt employees?

Exempt employees are typically salaried workers who are not eligible for overtime pay under the FLSA. Non-exempt employees must receive minimum wage and overtime pay for hours worked beyond standard thresholds.

What payroll records should employers keep?

Employers should keep payroll records such as timesheets, wage calculations, tax forms, deductions, and payment records. Under the FLSA, most payroll records should generally be retained for at least three years.

How often should payroll audits be conducted?

Most organizations should conduct payroll audits at least annually, though larger or multi-state employers may benefit from quarterly reviews. Regular audits help identify payroll errors, tax issues, and compliance gaps early.

How can employers stay compliant with remote employees across multiple states?

Multi-state payroll compliance requires employers to track employee work locations, apply correct state tax rules, and stay current with local wage and leave laws. Many organizations use global payroll or payroll processing platforms to help manage compliance across distributed teams.
