Setting up and operating a company in Taiwan involves more than simply conducting business activities. Companies must comply with a wide range of accounting, payroll, and tax obligations throughout the year, many of which are subject to strict filing deadlines and detailed documentation requirements.
For example:
- VAT returns are generally filed every two months.
- Withholding tax on payments to non-residents may need to be reported and paid within 10 days of payment.
- Social insurance enrollment must often be completed on an employee's first day of employment.
- Corporate income tax returns are generally due by the end of the fifth month following the fiscal year-end.
Failing to meet these requirements may result in penalties, additional tax assessments, or unnecessary administrative burdens. As a result, many foreign-invested enterprises and growing businesses choose to outsource their accounting, payroll, and tax compliance functions to experienced professionals.
This article outlines the key compliance obligations commonly encountered by businesses operating in Taiwan and the support services available to help them remain compliant and focused on growth.
In brief
- Multiple compliance obligations apply throughout the year.
- Taiwan businesses are generally required to maintain accounting records and file various tax returns on a recurring basis.
- Businesses often outsource payroll administration to improve efficiency and reduce costs.
- Annual corporate income tax return compilation is most effective when supported by accurate bookkeeping records.
- A proactive compliance strategy can help businesses avoid penalties and focus on their core operations.
Accounting & Bookkeeping Services
Accurate bookkeeping serves as the foundation for all tax compliance activities. Accounting records may be reviewed by tax authorities and should generally be retained in accordance with applicable record retention requirements. Proper bookkeeping also facilitates the preparation of annual financial statements and corporate income tax returns.
Payroll Services
Payroll administration involves more than salary calculations. Employers are responsible for:
- Enrolling employees in Labour Insurance, National Health Insurance, and Labor Pension schemes on their first day of employment.
- Calculating monthly payroll and statutory deductions.
- Reporting annual salary income by January 31 of the following year.
- Retaining payroll registers and supporting records for at least five years.
Outsourcing payroll administration can help companies improve operational efficiency, reduce administrative burdens, and ensure timely compliance with payroll-related requirements.
VAT Return Services
Most VAT-registered businesses in Taiwan are required to file VAT returns every two months, resulting in six VAT filings per year.
The VAT filing process generally involves:
- Reviewing the completeness of output VAT reporting
- Reviewing input VAT and assessing its eligibility for deduction
- Reconciling VAT-related accounts and balances
- Preparing and filing VAT returns
- Assisting with VAT payments and related compliance procedures
Timely and accurate filings help minimize compliance risks and avoid penalties.
Withholding Tax Return Services
Taiwan's withholding tax regime applies to a variety of payments, including:
- Professional service fees
- Rent
- Interest
- Commissions
- Payments to overseas entities or individuals
Particular attention should be paid to payments made to non-residents. Depending on the nature of the payment, taxes may need to be withheld and reported within 10 days of payment, and employment income paid to non-residents may be subject to 18% withholding tax currently.
Corporate Income Tax Return Compilation Services
Taiwan companies are generally required to file their annual Corporate Income Tax Return by the end of the fifth month following the fiscal year-end.
Preparing the return typically requires:
- Reviewing accounting records
- Preparing tax adjustments
- Reconciling accounting and tax differences
- Preparing tax computation schedules
Because the corporate income tax return relies heavily on the underlying accounting information, our CITR compilation services are generally provided together with our Accounting & Bookkeeping Services. This integrated approach helps ensure consistency, efficiency, and accuracy.
Why Outsource Accounting, Payroll and Tax Compliance Functions?
Many foreign-invested enterprises, startup businesses, and small-to-medium-sized companies choose to outsource their accounting, payroll and tax compliance functions rather than maintain dedicated internal resources.
The benefits of outsourcing may include:
- Ensuring business operations continuity and reducing key-person dependency
- Access to experienced professionals with up-to-date technical expertise
- Eliminating hidden employment and training costs
- Enhancing compliance with rapidly changed local regulations
- Reducing the risk of filing errors and missed deadlines
- Allowing management to focus on business growth and strategic priorities
An experienced service provider can help businesses navigate Taiwan's regulatory environment while ensuring that compliance obligations are managed accurately and efficiently.
Conclusion
Operating a business in Taiwan involves a variety of accounting, payroll, and tax compliance responsibilities throughout the year. From maintaining proper accounting records and processing payroll to preparing VAT returns, withholding tax filings, and annual corporate income tax returns, companies must establish reliable processes to meet their regulatory obligations.
Whether you are launching a new business in Taiwan or seeking support for ongoing compliance requirements, outsourcing these functions can help reduce administrative burdens, improve compliance, and allow management to focus on growing the business.
By working with experienced professionals, businesses can navigate Taiwan's compliance landscape with confidence and efficiency.
