Taxation (Employment Taxation)

What is employment taxation?

Employment taxation refers to the system of taxes imposed on employment income, including income taxes withheld from employee salaries and payroll taxes paid by employers. This encompasses personal income tax, social security contributions, and other mandatory taxes related to the employer-employee relationship.

For companies operating across the Asia-Pacific region, employment taxation is complex due to varying tax systems, rates, thresholds, and compliance requirements in each country. Proper tax compliance is essential to avoid penalties, legal issues, and reputational damage.
