Taiwan Payroll Outsourcing: What Businesses Should Know Before Getting Started

Introduction

Taiwan payroll touches three separate government bodies: the Bureau of Labor Insurance (BLI), the National Health Insurance Administration (NHIA), and the Bureau of Labor Funds. Each has its own registration process, its own filing schedule, and its own calculation method. None of them share data automatically.

For a company building its first Taiwan entity, that’s the part nobody really prepares for. The rules themselves aren’t the problem. It’s keeping three systems running correctly, in parallel, month after month, while the rest of the business is also scaling.

That operational load is what Taiwan payroll outsourcing is designed to absorb.

What Happens Before the First Payroll Runs

Taiwan payroll compliance starts before the first salary payment. Before a company can run payroll, it needs to complete the required employer registrations and enrol each employee in the relevant insurance and pension schemes. That registration process takes approximately five business days once all required documents are submitted.

The next step happens when an employee starts work. Employers must enroll new employees in:

• Labour Insurance
• National Health Insurance (NHI)
• Labour Pension

The employer needs to complete this enrolment on the employee’s first day of work. Coverage starts from the date the employer submits the enrolment. For example, if the employer waits until the employee’s fifth day to submit the enrolment, the employee has no coverage for the first four days. That gap can lead to employee disputes and potential regulatory penalties.

Taiwan does not provide a grace period for this requirement. Employers need to treat first-day enrolment as a fixed payroll and compliance step. A Taiwan payroll outsourcing provider can build this into its new-hire process, so the employer doesn’t have to rely on a manual reminder for every new employee.

To summarise, Taiwan’s payroll compliance starts before the first salary is paid. Pre-payroll registration and day-1 enrolment are two separate obligations that need to be completed correctly and in the right order.

The Monthly Payroll Obligations in Taiwan

Once the company completes its registrations and enrols its employees, the monthly payroll cycle follows two separate timelines. Income tax has one deadline, while social insurance and pension contributions follow another.

When Is Taiwan Payroll Tax Due?

Employers must withhold income tax from employee salaries and remit it to the tax authority. For most employees, the employer must make the payment by the 10th of the following month. The standard withholding rate is 5%, or the employer can use the applicable withholding table based on salary and the number of dependents.

Non-resident employees follow a different rule. Employees who spend fewer than 183 days in Taiwan during a calendar year generally face an 18% withholding rate. The employer must remit this tax within 10 days of the salary payment date, giving it a shorter deadline than the standard monthly process.

When Are Social Insurance and Pension Contributions Due?

Labour Insurance, National Health Insurance (NHI), and Labour Pension follow a separate payment schedule. Employers must pay these contributions by the 15th of the second month after the contribution month.

For example:

• January contributions → due by 15 March
• February contributions → due by 15 April

The relevant government agencies generally issue their bills around the 20th of the following month. Employers then need to reconcile those bills with their payroll calculations. The final amounts can sometimes differ from the company’s original calculations because the NHIA may make adjustments for factors such as dependent subsidies or changes in employee enrolment.

How Long Should Taiwan Payroll Records Be Kept?

Employers must retain payroll records for five years under Taiwan law. This includes:

• Payroll registers
• Payslips
• Bank remittance records
• Other relevant payroll documentation

Keeping these records accurately gives the employer a clear audit trail if the authorities later request supporting information.

Taiwan payroll runs on two separate monthly timelines: income tax is generally due by the 10th, while social insurance and pension contributions follow the 15th-of-the-second-month schedule. Employers need to track both separately.

Year-End and Annual Obligations

Taiwan’s payroll calendar has a January 31 convergence point. Everything comes due at once.

By January 31, employers must report all employees’ annual income to the tax authority: salary, stock-based payments, and taxable non-cash benefits. The same deadline covers second-generation NHI reporting to the NHIA. For companies with more than 50 employees, an Employee Welfare Committee is required by law as an independent tax reporting entity; any taxable benefits it distributes also fall under the January 31 reporting deadline.

Unused statutory annual leave can be carried over for one year under the Labour Standards Act. Leave not taken within that extended period requires monetary compensation at the employee’s most recent monthly salary. Overtime converted to compensatory leave that expires unused must be paid out at the overtime rate.

For an internal team managing Taiwan as one of several APAC markets, this is a crowded month. January 31 isn’t one deadline. It’s several landing at the same time.

What Changes With Taiwan Payroll Outsourcing?

Taiwan payroll outsourcing moves the day-to-day payroll work from your internal team to a local provider. The provider already understands the registration process, contribution tables and filing deadlines, so your team does not have to build that process from scratch.

• The Provider Handles Payroll Setup and employee enrolment.

A payroll provider can take care of the administrative work that happens before payroll starts.

This includes:

• Managing required registrations with the relevant authorities
• Enrolling new employees in Labour Insurance, NHI and Labour Pension
• Handling day-one enrollment requirements
• Setting up the payroll process and employee records

This removes much of the setup work from your HR or finance team and reduces the risk of missing an early compliance step.

• The Provider Manages the Monthly Payroll Cycle

Once payroll is running, the provider can manage the recurring calculations and filings.

This typically includes:

• Calculating salaries and statutory contributions using current salary brackets
• Reconciling social insurance bills with payroll calculations
• Remitting income tax within the required deadline
• Managing the separate deadlines for social insurance and tax
• Identifying non-resident employees who require the shorter 10-day tax withholding deadline
• Maintaining payroll records and payslips

Instead of your team tracking several deadlines across different government systems, the provider manages the payroll calendar for you.

• Year-End Payroll Becomes a Managed Process

The same applies to Taiwan’s annual payroll requirements.

A provider can coordinate:

• Annual employee income reporting
• Second-generation NHI reporting
• Employee Welfare Committee reporting, where applicable
• Year-end tax and payroll records

This is particularly useful around January 31, when several reporting requirements come together.

Outsourcing Does Not Remove the Employer’s Legal Responsibility

There is one important distinction to understand.

Payroll outsourcing transfers the work, but it does not automatically transfer the legal responsibility. If the provider submits an incorrect or late filing, the employer can still face the resulting penalty.

That makes provider selection important. Before signing, employers should understand exactly what the provider handles, who checks each filing, and how the provider manages changes to Taiwan’s payroll rules.

How to Choose a Taiwan Payroll Outsourcing Provider

Choosing a Taiwan payroll provider is about more than comparing monthly fees. The right provider should have a clear process for employee enrolment, statutory filings, payroll reconciliation and tax deadlines. Before signing a contract, ask how the provider handles the following areas:

• How Does the Provider Handle Day-One Employee Enrolment?

Employee enrolment needs to happen from the employee’s first day of work. The provider should have a clear internal process for collecting employee information, submitting the required registrations and confirming that coverage starts on time.

Ask the provider:

• When does the enrolment process start?
• Who checks the employee’s documents?
• Who confirms that the enrolment has gone through?
• What happens if the employee joins on a holiday or outside normal working hours?

A vague answer about “ensuring compliance” isn’t enough. The provider should be able to explain the actual workflow.

• How Does the Provider Reconcile Social Insurance Payments?

Taiwan’s social insurance bills don’t always match the company’s original payroll calculations. The NHIA can make adjustments based on changes such as dependent status or employee enrolment.

Ask how the provider:

• Compares government bills with payroll calculations
• Identifies differences
• Handles adjustments
• Communicates additional charges or corrections to the client

A provider should have a defined reconciliation process rather than simply passing the government bill to you.

• Who Tracks Taiwan Payroll Deadlines?

Taiwan payroll involves several deadlines throughout the year. Your provider should clearly assign responsibility for each one.

Ask who is responsible for:

• Monthly income tax payments
• Social insurance and Labour Pension payments
• Annual income reporting
• NHI reporting
• Other statutory filings

You should also know who checks that each submission has been completed successfully. Shared responsibility can create gaps if nobody has clear ownership of the final submission.

• How Does the Provider Handle Non-Resident Tax Withholding?

Non-resident employees follow different tax withholding rules from Taiwan tax residents. Employees who spend fewer than 183 days in Taiwan during a calendar year can face an 18% withholding rate, with the tax generally due within 10 days of salary payment.

If you plan to hire foreign employees, ask the provider specifically how it identifies non-resident employees and manages the shorter filing deadline.

What Should You Look for in a Taiwan Payroll Provider?

A good provider should be able to give you clear answers about its processes, not just promise that it will “handle compliance”.

Before choosing a provider, make sure you understand:

• Who handles employee enrollment
• Who calculates and reconciles statutory contributions
• Who owns each filing deadline
• How the provider handles non-resident employees
• Which services are included in the monthly fee
• What happens when payroll errors or government adjustments occur

The goal isn’t simply to find a provider that can process payroll. It’s to find one that can consistently manage the Taiwan payroll compliance process behind it.

Taiwan payroll has a predictable structure once you’ve seen it in full: three bodies, two monthly timelines, one year-end convergence point. Getting it right from the start is easier than fixing it after the first compliance gap appears.
